- It is predicted that the demand for polypropylene staple fiber in 2023 will be......! [11/10/2020]
- About 952,000 tons were consumed in 2018, accounting for 11% of global nonwovens consumption. Although the use of polypropylene staple fiber in the disposable market has declined, especially the demand for dry-laid thermal bonding covering materials (only partially compensated by the use of air-laid), this fiber is in the durable nonwoven market Continues to grow. Most of the durable end markets for polypropylene are needlepunch durables. The main markets where needle-punched polypropylene is used include geotextiles, automotive parts, coating substrates, indoor/outdoor carpets, blankets, upholstered furniture and mattresses. The forecast of global demand for polypropylene staple fiber in 2023 is 1.1 million tons.......

- The polypropylene staple fiber industry needs to be "targeted" [11/3/2020]
- Polypropylene is the trade name of polypropylene fiber. It is widely used in the manufacture of industrial fabrics, non-woven fabrics, etc., such as carpets, ropes, industrial filter cloths, fishing nets, building reinforcements, oil-absorbing blankets, and decorative cloths. It was started in 1957. Industrial production.Among the five major chemical fibers, polypropylene is the only chemical fiber product that has been successfully independently developed in my country. The production technologies such as polyester, nylon, acrylic and vinylon are all imported from abroad. However, while my country's polypropylene staple fiber industry has advantages in independent research and development, it also has some shortcomings.First of all, the scale of my country's polypropylene staple fiber enterprises is not large enough, and low-level repeated construction is serious.Secondly, because Chinese enterprises do not pay enough attention to product production technology and quality, the structure of my country's polypropylene staple fiber products is unreasonable. For example, in the conventional product market, there are too many production companies and market competition is fierce; in some high-end product markets, there are only a few companies, and the product prices are relatively high; while in some special fields, almost no companies are involved, and polypropylene products are blank.Therefore, my country’s polypropylene staple fiber industry needs to give play to its own comparative advantages, while accelerating the adjustment of the industry’s structure, intensify the research and development of new products, and actively introduce foreign advanced technology and equipment to improve the competitiveness of the entire industry.From a global perspective, the production capacity of polypropylene fiber is excessive. Therefore, in the future, the development of my country's polypropylene staple fiber industry cannot be limited to the supply and demand relationship in the market, and the focus of development should be placed on product quality and product differentiation.......
- Printing and dyeing factory is too difficult! A notice of dyeing fee increase with a full official seal, the workshop cannot recruit workers [10/26/2020]
- Recently, a price increase notice has been circulated in the printing and dyeing circle of friends. Fifteen textile printing and dyeing companies have stamped the notice and decided to adjust the dyeing and finishing fees from October 28, 2020. Look at the following report Recently, dyeing factories have adjusted their dyeing fees. This is not news. Fifteen textile companies stamped on a notice, which is also a matter of industry shaking. We know that since this period of time, the textile and apparel industry has recovered as a whole, market demand has increased significantly, and the upstream industry chain has been booming. With this, the price of raw materials such as cotton, polyester, dyes, etc. has risen across the board, and due to the surge in orders, employees are in short supply. , Had to recruit high-priced temporary workers for emergency situations, and it was difficult for employees to recruit and find everything.2.pngIn the textile market, it is constantly reported that trucks for loading in grey fabric factories have to line up, and trucks for warehousing in dyeing factories have to line up. There are not enough trucks in the market. Immediately after the warehouses of some weaving factories were emptied, the stocks were gone, and some dyeing factories began to blow up their warehouses. Is it true that only a "cold winter" news can stir up the textile market that has been silent for more than half a year so lively? 1. Finished product market stocking and winter fabric orders "crash" Those who are familiar with the fabric market know that around October and November in the second half of the year, the finished product spot market on the market will usher in a relatively concentrated stocking up before the year. This is also the more common "market order" in the market. This period of time has a large number of orders, limited types, and short duration. This time period is now, and orders are coming more obviously than in any previous year. The main reason for this situation is that the foreign epidemic situation is serious, and a large number of overseas clothing companies have closed down. This has led to a sharp decline in clothing and fabric trade in the past six months. Now their inventory has bottomed and it is time to replenish. 2. End-of-year replenishment in the domestic fabric marketAlso because of the extremely limited number of orders throughout the first half of the epidemic, many textile and apparel companies missed the spring and summer markets and had high inventories. Lack of confidence in the future market has led to insufficient enthusiasm for stocking in the spot market. Today, the backlog of replenishment demand is concentrated, and all kinds of orders are on the battlefield. The current winter clothing fabric orders are encountered. The market will burst the next time, reaching the level of this year. The highest peak of the market.3. Dual factors at home and abroad drive industry development"At present, our orders have been queued to January next year, and we are now in full capacity production. In September, the company's output value increased by about 25% year-on-year." Wugang Knitting Co., Ltd. is the president of the Municipal Knitwear Industry Association, specializing in the production and sales of various The products are mainly supplied to downstream apparel companies. The chairman of the company, Wu Gang, learned from customers in Henan, Shandong, Sichuan and other places that some clothing companies have sold out the inventory of the previous two years. In his analysis, the domestic textile and apparel industry's recovery is mainly due to the superimposed influence of domestic and foreign dual factors.On October 19, the workshop of Wugang Knitting Co., Ltd. in the Huadian functional area of the development zone was busy. In order to catch up with the goods, even office staff joined the production line. Compared with the first half of this year, such a scene looks like a two-fold sky.On the one hand, in the second half of the year, a large number of textile and apparel orders were transferred from abroad to domestic. Affected by the epidemic, many textile and apparel companies in India, Pakistan and other countries cannot guarantee normal delivery. In order to ensure continuous supply, European and American retailers have transferred a large number of orders to China for production. According to public data, in August, national textile exports totaled US$14.72 billion, a year-on-year increase of 47%; clothing exports totaled US$16.21 billion, a year-on-year increase of 3.2%, achieving positive monthly growth for the first time this year.Secondly, the steady recovery of the domestic economy has driven demand growth and the arrival of the traditional "golden nine silver ten" consumption season has also stimulated textile and apparel consumption.However, Wu Gang said that the surge in textile and apparel orders from abroad is mainly from more developed regions such as Europe and the United States, while the growth in regions such as the Middle East and Africa is not obvious.The rapid increase in orders in the short term has also brought new troubles to textile and garment companies-the prices of raw materials such as dyes, cotton, and polyester in the upstream have soared, and it is difficult to find a single product."In the first half of the year, because of the downturn in the market, upstream companies are controlling inventory." Wu Gang said that after the rapid increase in clothing output, raw materials such as yarns are in short supply, prices have risen by about 10%, and delivery is uncertain. In the past, when you buy yarn, you can get it in two or three days after you make a payment. Nowadays, it may not arrive after you make a payment for more than half a month. Wu Gang said frankly that he has been in the textile industry for more than 20 years and has not encountered such a situation in ten years. "In 2010, multiple factors at home and abroad have superimposed and the price of raw materials has skyrocketed, causing many clothing companies to be overwhelmed. At present, the 10% increase in raw materials is still within the normal range, and will not have a great impact on the subsequent development of the industry. "However, not all raw materials in the textile and apparel industry are in short supply and prices are soaring. Zhejiang Feixiang Thread Industry Co., Ltd., located in Changsonggang Functional Zone of the Development Zone, mainly produces gold and silver wires, gold and silver threads and other products. As a niche category of decorative clothing accessories, its sales are mainly subject to fashion trends and are not greatly affected by the general environment. Therefore, prices and sales are relatively stable.2 Recently, some textile fabric enterprises in Quanzhou reported that they have contacted many diverted orders from European and American customers in India, Pakistan, and the Middle East, which was rare in the past. However, since most of them are low-end textile and fabric products, it remains to be seen and follow-up negotiations whether these orders can actually land in Quanzhou. Quanzhou North Textile's Zhang Zishe recently suddenly received a request for negotiation of textile fabric orders diverted from India. He said, “In the past, we could not receive a single order from India.” According to him, this year, affected by the epidemic, some European and American end customers have delivered orders to Indian textile companies. The question is, "These foreign customers are now placing orders for next summer's clothing, which will be confirmed by September in previous years, but this year to now, they are still looking for order-manufacturing companies worldwide." Zhang Zishe is not the only person in Quanzhou who has contacted India to diversify orders. According to a person in charge of the Shishi Fabric Industry Association, many of their member companies have recently received diversion orders from the Middle East, India and Pakistan, but most of them are low- and medium-grade fabrics. Therefore, the textile industry generally judges these so-called "diversion orders" as "emergency orders." "I think that more orders of this kind are an emergency move. The transfer speed is fast, and buyers pay more attention to factors such as price and processing speed. Once India's production capacity is restored, the domestic production cost advantage will decrease, and whether the orders can stay in the country for a long time needs further Observation." said a researcher in the textile industry of the China Securities Futures Agricultural Products Team.Although the negotiations are still ongoing, Zhang Zishe believes that because these orders are generally low-end products, and the current domestic production costs are much higher than those in India and other places, the profit of receiving orders is too low, so it is possible to really land. Little sex. "Recently, the price of domestic cotton yarn and other raw materials has risen by 15%, and chemical fiber has also risen by at least 3%. This is only in terms of raw materials. In terms of labor, the current salary of lathes is 6,000 yuan a month, while in Southeast Asia only 700 yuan. These should originally be South Asia. If the orders made in Southeast Asian countries are transferred to us, the production cost will increase a lot, which is estimated to be unacceptable to many foreign customers."In this regard, Shi Zhengzhi, secretary general of the Quanzhou Textile and Apparel Chamber of Commerce, said: “Recently, we have also noticed reports that Indian orders have been transferred to China, but as far as I know, from the perspective of major textile exporting countries in the world, China, Vietnam, and Bangladesh , Turkey ranks in the top four, and India ranks fifth at most, with an annual export volume of less than US$10 billion. Therefore, even if some of India’s textile orders are transferred to China, the overall situation is relatively limited." According to the introduction, most of the textiles produced in India are middle and low-end products. Many years ago, my country's low-end textile processing has been transferred to Southeast Asia. Indian cotton only produces three seasons a year, and the fiber is relatively short, which can only produce low-end products, while my country's Xinjiang cotton can produce four seasons a year, and the fiber is relatively long. Therefore, the finished products of India's textile industry are far inferior to ours. "So on the whole, the so-called order transfer has a very limited impact on the production of the textile industry in Quanzhou." Shi Zhengzhi said.3"Jordan Times" reported on October 20 that the clothing industry representative of the Jordan Chamber of Commerce stated that imports of winter clothing and footwear fell to 60 million yoy this year, down 14% year-on-year, and 10 million yoy less than last year.......
- Analysis on the status quo of import and export of polypropylene staple fiber [10/26/2020]
- From the perspective of foreign markets, the United States has developed a variety of functional polypropylene staple fibers such as antibacterial, flame retardant, antistatic, and antifouling 10 years ago. Western European countries have also successfully developed conductive, electric heating, bio-absorbable and degradable polypropylene. Especially in Japan, it has increased its investment in the research and development of functional polypropylene staple fiber and high-performance fiber, continuously introduced high-tech new products, and emphasized its use in decoration and industrial use, and broadened the application field of textiles. Japan's polypropylene functional textiles account for about 40% of its total textiles, or even a higher proportion. Mitsubishi Japan launched the environmentally-friendly polypropylene "Mitsubishi Pylen" earlier.With the development of my country's polypropylene staple fiber technology, it has gradually become an important import and export country for polypropylene staple fiber. Data shows that from January to October 2019, my country's polypropylene staple fiber imports reached 248.2 tons, with an import value of 495,000 US dollars.......
- Overview of the staple fiber industry: basic knowledge of staple fiber spot [9/22/2020]
- Polyester staple fiber (hereinafter referred to as staple fiber) is a staple fiber obtained by spinning, drawing, and cutting polyester (PET) produced by polymerizing PTA and ethylene glycol in a molten state. Since entering my country in the 1970s, due to its wide range of uses and low prices, the market scale has developed rapidly, and it has become an important raw material for textile, clothing, home textiles and other industries. Raw materials and technology According to different classification standards, staple fiber can be divided into different categories. According to raw materials, it can be divided into primary staple fiber and regenerated staple fiber. Primary staple fiber is made from PTA and ethylene glycol through polymerization, spinning, and cutting. It is commonly known as "large chemical fiber"; recycled staple fiber is mainly made of recycled PET bottles as raw materials, and is dried, melted, and spun. It is made by cutting silk, commonly known as "small chemical fiber". Primary staple fiber is divided into melt direct spinning and intermittent spinning according to different spinning production processes. Melt direct-spun staple fiber is made of PTA and ethylene glycol as raw materials. After the polyester melt is produced, it is directly spun and cut to produce staple fiber without the process of producing polyester chips. At present, the production of conventional domestic staple fibers basically uses melt direct spinning technology. Intermittent spinning, also known as chip spinning, is a process of producing fibers from PET chips. Compared with the melt direct spinning process, batch spinning reduces the polyester equipment and adds the chip drying and melting equipment, and the subsequent processes are basically the same. Downstream applications Staple fibers are mainly divided into three categories according to different uses: for spinning, filling, and non-woven. Spinning yarn is the main purpose of staple fiber, including cotton spinning and wool spinning. Cotton spinning and wool spinning refer to spinning with cotton and wool fibers respectively. The amount of cotton spinning is relatively large, mainly including pure polyester spinning, polyester-cotton blended spinning, polyester-viscose blended spinning and the production of polyester staple fiber sewing thread. Wool spinning mainly includes polyester/acrylonitrile, polyester/wool blending and making blankets. Filling is mainly staple fiber in the form of fillings, used as home furnishing fillings and clothing warming materials, such as bedding, cotton clothing, sofa furniture, plush toys, etc. Most of these staple fibers are hollow polyester staple fibers. Nonwovens are an extension of staple fiber use and have developed rapidly in recent years. Non-woven fabrics are widely used. For example, spunlace non-woven fabrics are mainly used in wet wipes, medical and other fields, and geotextiles, leather-based fabrics, and linoleum-based fabrics are mainly used in engineering fields. At present, the largest proportion in the market is polyester staple fiber products for primary spinning.......
- What effect does static electricity have on polypropylene staple fiber? [9/22/2020]
- Polypropylene staple fiber is a kind of non-absorbent or very low water absorption, and cannot be dyed and colored like other synthetic fibers such as polyester and eyeglass. Because of its high static electricity, it is difficult to perform processing such as clearing and spinning, which greatly limits Based on its application, the high-efficiency, durable, practical antistatic agent and dyeable components were analyzed and screened.Polypropylene staple fiber is because polypropylene is located at the negative end of the fiber frictional charging sequence, so when it rubs against a fiber, it generates a negative charge. This kind of fiber without modification treatment is prone to static electricity accumulation during use and can cause many troubles in the processing process. Severe static electricity problems will directly affect the cleaning, carding and other processes, and it cannot even be used for processing.......
- Operation of chemical fiber industry from January to July 2020 [9/15/2020]
- From January to July 2020, the domestic and foreign demand markets for textiles and apparel will continue to be repaired. However, due to the accumulation of high inventories in all links of the textile industry chain, the recovery of terminal demand in the chemical fiber industry is weak, and some indicators are improving. There have been repetitions, the export pressure of chemical fiber is still relatively large, and the economic benefits have continued the recovery trend in the first half of the year.Textiles and garments need to gradually pick up inside and outsideAccording to data from the National Bureau of Statistics, from January to July, the national retail sales of clothing, shoes, hats, and knitting textiles above designated size decreased by 17.5% year-on-year, and the decline was 2.1 percentage points smaller than that from January to June; Retail sales of such commodities fell by 0.9% year-on-year, and the rate of decline narrowed by 2.0 percentage points from January to June. However, from the perspective of direct chemical fiber demand, from January to July, the output of cotton blended yarn and cotton blended fabrics decreased by 2.39 and 1.24 percentage points respectively from January to June; the output of chemical fiber yarns and chemical fiber staple fabrics decreased by 1- It continued to narrow in June. The output growth rate of nonwovens still maintained a relatively high growth, with a year-on-year increase of 10.97%, an increase of 4.42 percentage points from January to June. According to China Customs data, my country's textile and apparel exports from January to July were US$156.482 billion, a year-on-year increase of 5.57%, and the growth rate was 2.41 percentage points higher than that from January to June.The trend of narrowing decline in chemical fiber output has repeatedAccording to statistics from the National Bureau of Statistics, the output of chemical fiber from January to July 2020 was 33.098 million tons, a year-on-year decrease of 2.38%, which was 1.4 percentage points deeper than that from January to June. This is the first time since March that the decline in chemical fiber output has continued to narrow. repeatedly. Among them, the output of polyester was 26,342,300 tons, a year-on-year decrease of 1.87%, and the output of nylon was 2,349,400 tons, a year-on-year decrease of 0.16%, both of which turned from positive growth to negative growth from January to June; the output of viscose staple fiber was 2,824,700 tons, a year-on-year decrease of 7.82% , The decline continued to narrow; spandex output was 455,200 tons, an increase of 0.88% year-on-year, and the growth rate remained stable.Chemical fiber outlet pressure is still highAccording to China Customs data, my country imported 439,400 tons of chemical fiber from January to July, a year-on-year decrease of 17.73%, and the decline was 2.53 percentage points deeper than that from January to June. In terms of exports, the chemical fiber exports from January to July were 2.3163 million tons, a year-on-year decrease of 19.02%. Compared with January to June, although there was still a narrowing trend, the decline only narrowed by 0.19 percentage points. Among them, the export of polyester staple fiber was 410,100 tons, a year-on-year decrease of 31.77%, the export of polyester filament was 1,366,600 tons, a decrease of 14.57%, the export of viscose staple fiber was 193,400 tons, a decrease of 20.62%, and the export of viscose filament was 35,300 tons. A year-on-year decrease of 30.50%, and the rate of decrease was less than 1 percentage point from the January-June period, indicating that the export market for chemical fiber products is still under pressure.Economic benefits continue the restoration trend in the first half of the yearAccording to data from the National Bureau of Statistics, from January to July 2020, the main business income of the chemical fiber industry was 431.9 billion yuan, a year-on-year decrease of 17.33%, and the decline was 1.05 percentage points smaller than that from January to June; the total profit realized was 8.510 billion yuan, a year-on-year decrease of 40.36 %, the decline narrowed by 1.50 percentage points from January to June. The loss of the industry was 41.84%, which was 2.41 percentage points less than that from January to June; the loss of loss-making enterprises increased by 64.13% year-on-year, and the growth rate fell by 7.56 percentage points from January to June.Cautious investment, shrinking fixed asset investmentAccording to data from the National Bureau of Statistics, from January to July 2020, the fixed asset investment in the chemical fiber industry fell by 21.2% year-on-year, which was 4.3 percentage points deeper than that in the first half of the year. It failed to continue the trend of slowing down in the first half of the year. It shows that under the circumstance of sluggish market demand, corporate investment remains cautious, and it will take time for investment confidence to recover.(Source: China Chemical Fiber Industry Association)......

- The number of participants in new cotton is gradually increasing, and the output is slightly lower than last year [9/10/2020]
- At present, the domestic new-year cotton is successively listed, especially in the mainland market. Recently, it has gradually entered the stage of concentrated picking, and the supply of seed cotton is increasing day by day. According to Longzhong's understanding, the current purchase price of seed cotton in the Yellow River Basin is 3.10-3.20 yuan/kg, with a moisture content of 15%-16% and a lint content of 37-38. Although the daily acquisition volume is still small, the number of acquired companies continues to increase. The manufacturer said that it is expected that around the 15th, the supply will increase significantly, and the acquisition work will return to normal. In Xinjiang, a small amount of hand-picked cotton flows to the market, but the purchase and sale prices are relatively high. Most of the machine-picked cotton in northern Xinjiang will be mined on September 15-20, and the late-maturing machine-picked cotton in eastern and southern Xinjiang is expected to be mined in mid to early October.Based on the current prices in various places and the estimated prices, the cost price of lint in the Yellow River Basin in the mainland is about 13,000 yuan/ton, which is basically in line with the current market price.......
- The main physical and chemical properties of polypropylene staple fiber! [9/10/2020]
- 1. Form The longitudinal surface of polypropylene is straight and smooth, and the cross section is round.2. Density The biggest advantage of polypropylene fiber is its light texture. Its density is only 0.91g/cm3, which is the lightest variety among common chemical fibers. Therefore, polypropylene fiber of the same weight can obtain a higher coverage area than other fibers.3. Strength and elongation Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene fiber has good abrasion resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables.4. Light moisture absorption and dyeing properties, good warmth retention; almost no moisture absorption, but strong absorption capacity, and obvious moisture absorption and perspiration effect; polypropylene fiber has low moisture absorption and almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero . But it has a wicking effect and can transfer water vapor through the capillary in the fabric, but it does not have any absorption effect. The dyeability of polypropylene is poor and the chromatogram is incomplete, but the original solution coloring method can be used to make up for the deficiency.5. Acid and alkali resistance Polypropylene fiber has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene fiber has good resistance to acids and alkalis, so it is suitable for use as filter materials and packaging materials.6. High strength The strength of polypropylene stretch yarn is second only to nylon, but the price is only 1/3 of that of nylon; the fabric made of it has stable dimensions, good wear resistance and good chemical stability. However, it has poor thermal stability, is not resistant to sunlight, and is prone to aging and brittle damage. Therefore, anti-aging agents are often added to polypropylene......
