The company has passed ISO9001:2015 international quality system certification.The term short fiber can often be seen, so what kind of fiber can be called short fiber, how to distinguish between polypropylene staple fiber and other fibers?In order to facilitate a more in-depth understanding of polypropylene staple fibers, first of all, it should be clear that the lengthened fiber, plus staple fiber and the matrix of long fiber, staple fiber, these four have completely different concepts, sometimes easy to be confused, so it is important to recognize them.Lengthened and added staple fibers and long fibers in the matrix Staple fibers are not a single concept. Extended fiber is a continuous long glass fiber, and short fiber is a short fiber cut several millimeters in length. The concept of long fiber and short fiber in the matrix is generally 1mm length as the limit, greater than or equal to 1mm for long fiber, less than 1mm for short fiber. Therefore, the lengthened fiber can be made into a growth fiber or a short fiber; The addition of staple fiber can also be made of growth fiber or staple fiber.It is not difficult to see from their concept, although the concept is different, but there is a single connection between each other, it can be extended to polypropylene staple fiber and long fiber, the limit length of the fiber is also about 1mm, less than 1mm is polypropylene staple fiber.In recent years, Jiangsu Haibang New Materials Co., Ltd. has developed a large number of polypropylene short fiber varieties, including high-speed iron foundation high strength high modulus polypropylene, lightweight GMT hot melt polypropylene, automotive structural parts strengthened polypropylene, liquid filtration adsorption polypropylene, wear-resistant high strength polypropylene, low odor low VOC polypropylene, dyeing polypropylene, halogen-free flame retardant polypropylene and other cutting-edge fiber products. It replaces many import needs. We have successfully served polypropylene staple fiber products in high-end industries such as high-speed railway, Three Gorges Dam, all kinds of medium and high-end automobiles, direct drinking water, etc., and the product quality has reached a high level, saving a lot of investment for national projects.

- How should textile enterprises cope with the off-season? [7/9/2024]
- With the temperature quietly rising, the textile market seems to have ushered in the usual off-season. However, behind this seemingly calm market, there is quietly brewing a fluctuation in the price of fabrics. How should textile enterprises cope with this challenge?The rising price of fabricsAfter in-depth market research, the fabrics with rising prices are mainly concentrated on 380T-420T specifications of nylon spinning. Mr. Wu, a senior figure in the fabric industry, revealed: "This specification of nylon spinning, the price per meter has risen by 2-3 cents, the increase is quite significant." In addition to nylon spinning, although the price of other specifications of the original cloth has also fluctuated, but on the whole, its increase is far less than that of nylon spinning.Mr. Jiang, the head of another weaving company, also confirmed the trend: "Our T400 and T800 series products have also increased prices recently, but the increase is relatively small." This shows the diversity and complexity of the fabric market prices.Fluctuations in raw material pricesWhen it comes to the reasons for the rise in fabric prices, many people first think of fluctuations in raw material prices. Since late May, polyester factories have increased the price of polyester filament, and the increase has lasted for more than a month. The price fluctuation of different specifications is between 500-700 yuan/ton, which undoubtedly brings cost pressure to fabric enterprises.However, it is important to note that while rising raw material prices are a common phenomenon in the market, not all fabrics are equally affected. For example, the raw material for nylon spinning is nylon, and the price of nylon has not risen significantly recently. In addition, the price of gray fabrics made of large amounts of polyester filament has not fluctuated significantly. This shows that rising raw material prices are only a factor in rising fabric prices, not the only reason.Coping strategies of textile enterprisesIn the face of fluctuations in the fabric market, textile enterprises have shown different coping strategies. Some companies choose to purchase raw materials or fabrics in advance to lock in costs and reduce the impact of market fluctuations; Others maintain stable production and operation by maintaining a high operating rate; There are also enterprises that focus on product differentiation development and pursue higher profit margins.In this ever-changing market, no one strategy is a one-size-fits-all. Only by finding a suitable development path can we be invincible in the fierce market competition.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.......

- How to reduce carbon emissions while maintaining economic development [7/2/2024]
- With the serious challenge of global climate change intensifying. All walks of life are looking for ways to actively reduce emissions. At present, the textile industry is facing multiple pressures of low carbon and sustainable development. How to achieve a significant reduction in carbon emissions while ensuring economic development has become a problem that the textile industry must face and solve.At present, textile fiber raw materials, processing dyes or additives produce a lot of wastewater and pollutants, and the production process is highly dependent on direct energy resources such as coal, electricity, oil and natural gas, including water resources consumption, energy consumption, wastewater discharge, waste treatment and so on. At the same time, the Progress report of the "Fashion Brand 30·60 Carbon Neutral Acceleration Plan" shows that the current annual greenhouse gas emissions of China's textile and garment industry are about 230 million tons, accounting for about 2% of the national emissions, accounting for 2.8% of the national industrial carbon emissions.In order to win the 2% "carbon reduction" war, small and medium-sized enterprises are an indispensable part of China's carbon peak and carbon neutrality. 99.8% of textile enterprises are small, medium and micro enterprises, and 86.8% of textile employees are from small, medium and micro enterprises.Technological innovation is also the key to carbon reduction in the textile industry. It is necessary to increase the research and development of textile machinery, printing and dyeing technology, promote high-efficiency and energy-saving textile equipment and processes, and improve energy efficiency. At the same time, we should actively explore the application of green fibers, degradable dyes and other environmentally friendly materials to reduce the impact on the environment.The government should strengthen policy guidance and formulate policies and measures conducive to the carbon reduction of the textile industry. For example, increase support for green textile enterprises, provide tax incentives, financial support and other policy support; Establish green textile certification system to improve consumers' awareness and acceptance of green textiles; Strengthen industry supervision and promote textile enterprises to implement emission reduction responsibilities.The textile industry to win the 2% carbon reduction war is a difficult and urgent task. Only when we fully recognize the importance of carbon reduction in the textile industry, clear carbon reduction targets and formulate action plans, promote technological innovation to improve energy efficiency, develop circular economy to promote waste resources, strengthen policy guidance to form joint efforts and strengthen international cooperation to cope with climate change can we achieve it.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.......
- How about the performance of polypropylene staple fiber? [6/27/2024]
- Polypropylene staple fiber has its own advantages and characteristics compared with polyamide fiber, polyester fiber light, viscose fiber light, polypropylene staple fiber polypropylene resin as the main raw material, through melt spinning, drafting, crimping, drying, cutting, packaging and other processes to produce colored and colorless, specified denier and length of fluffy fiber.Polypropylene staple fiber light, its density of 0.9 ~ 0.92 grams/cubic centimeter, in all synthetic fibers is the lightest, it is 20% lighter than polyamide fiber, 30% lighter than polyester fiber, 40% lighter than viscose fiber; High strength (dry and wet state of the same), good wear resistance and resilience; Anti-microbial, no mold and no decay; Chemical resistance is also better than the general synthetic fiber. In addition, compared with other synthetic fibers, polypropylene fiber has good electrical insulation and heat retention, its resistivity is very high (7×1019 ohms · cm), and its thermal conductivity is very small.However, the melting point of polypropylene staple fiber is low (165 ~ 173℃), and the stability of light and heat is poor, so the heat resistance and aging resistance of polypropylene staple fiber are poor, and the heat stabilizer and anti-aging agent are usually added to improve its performance. Its hygroscopic and dyeing properties are the worst in synthetic fibers, the moisture recovery rate is less than 0.03%, and ordinary dyes can not make it colored, so a certain amount of coloring masterbatch is added to raw polypropylene in spinning to make the fibers colored.Jiangsu Haibang New Material Co., LTD., formerly known as Taizhou Hailun Chemical Fiber Co., LTD., is a technology-based chemical fiber enterprise specializing in research and development, production and sales of polypropylene staple fiber.

- Limited production enterprises continue to increase through the industry off-season [6/26/2024]
- According to the feedback of some cotton textile enterprises in Henan, Anhui, Shandong and other places, the cotton yarn inquiry/shipment has continued to slow down since mid-May, the yarn accumulation rate has been rising (the inventory of finished products of individual textile enterprises has risen to a near month high), coupled with the downstream textile factory/fabric/clothing enterprises partly or fully on credit, 1-3 month account period and other procurement modes are becoming more and more. Cotton mills can only choose between sales and cash flow, so it is difficult to change the growth of the proportion of cotton mills/cloth mills to limit production and reduce production.From the survey, in recent days, cotton textile factories in some areas have more high-temperature holidays, ranging from 3-5 days to 10-15 days, and pay basic living expenses to employees. Some enterprises although the conversion of differentiated yarn, blended yarn (including CVC) and Lyocell yarn, but because the market production, demand is also in a saturated, supersaturated state, conversion is not easy, shipment is not easy, so the growth of cotton yarn stock slowed down, but other yarn inventory also continued to accumulate, a lot of money.A medium-sized cotton factory in Texas said that in recent years, Xinjiang's production capacity continues to expand, squeezing the mainland's pure cotton production capacity, mainland textile enterprises can only try to avoid the competition with the same count, the same index of Xinjiang cotton yarn, but this year C50S and above high-count yarn market demand not only did not grow but continued to shrink, blended yarn, new fiber yarn, differentiated cotton yarn market expansion space has been very limited. The cotton mill is also competing for customers to a white-hot degree, and the new conversion enterprises want to share a piece of the pie is not easy. The company believes that for cotton mills, it is necessary to maintain the stability of cash flow and skilled workers through a series of measures such as limiting production, reducing production and dumping inventory, survive the off-season in June to August, and meet the arrival of "gold nine silver ten", to ensure that it does not fall before dawn.Since June, cotton prices fell significantly higher than cotton yarn, cotton mill immediate profits continue to recover, most of the textile enterprises think it is of little significance, on the one hand, cotton mill raw material inventory is mostly in about 1 month, the current cost of cotton spinning is still at a high level; On the other hand, textile enterprises currently do not value spinning profit margins, and the focus is on how to speed up yarn destocking and timely recovery of loans, in order to achieve the purpose of maintaining production and scheduling orders during the dry period.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.......

- Understand the physical and chemical properties of polypropylene! [6/19/2024]
- Physical and chemical properties of polypropylene1. The vertical surface of the form polypropylene is flat and smooth, and the cross-section is circular.2. The biggest advantage of density polypropylene is its light texture, and its density is only 0.91g/cm3, which is the lightest variety of common chemical fibers, so the same weight of polypropylene has a higher coverage area than other fibers.3. Strong extensional polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. So polypropylene wear resistance is good. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is the ideal material for making fishing nets and cables.4. Hygroscopic and dyeing polypropylene has very little hygroscopic properties, almost no hygroscopic properties, and the moisture regain rate under general atmospheric conditions is close to zero. However, it has a core suction effect, which can transfer water vapor through the capillary tubes in the fabric, but does not have any absorption effect itself. The dyeing property of polypropylene is poor and the chromatography is incomplete, but the method of stock solution coloring can be used to make up for the deficiency.5. Acid and alkali resistant polypropylene has good chemical resistance, in addition to concentrated nitric acid, concentrated caustic soda, polypropylene has good resistance to acid and alkali, so it is suitable for filter materials and packaging materials.6. Light resistance and other polypropylene light resistance is poor, thermal stability is also poor, easy to age, not resistant to ironing. However, the anti-aging properties can be improved by adding anti-aging agents during spinning. In addition, the electrical insulation of polypropylene is good, but it is easy to produce static electricity during processing.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.......
- The antistatic property of polypropylene staple fiber is also different! [6/11/2024]
- The antistatic property of polypropylene staple fiber is also different!There are many types of polypropylene staple fibers in the use of antistatic agents, simply divided into several types with ionic properties, and these types have their own advantages and disadvantages. Firstly, the antistatic effect of anionic type is poor, and its water solubility is good, easy to be washed off, so the durability is poor; The cationic type has good antistatic effect and good smoothness and absorption. However, toxic and corrosive, most of them are used for surface finishing, although the amphoteric type has the antistatic properties of the above two, it is easy to fade at high temperatures and the price is more expensive.Then there is the non-ionic type: good durability, low toxicity, suitable for fiber blending, but it will affect the dyeing of the fiber. Based on the above points, a compound antistatic agent was prepared. In order to facilitate production and disperse the antistatic agent evenly, the antistatic agent was first processed into masterbatch. The antistatic masterbatch is made by twin-screw extruder granulator. The antistatic agent, dispersant and carrier are mixed and coated in a certain proportion. In this way, the antistatic property of the polypropylene staple fiber produced has been greatly improved.Jiangsu Haibang New Material Co., LTD., formerly known as Taizhou Hailun Chemical Fiber Co., LTD., is a technology-based chemical fiber enterprise specializing in research and development, production and sales of polypropylene staple fiber.

- China's textile enterprises actively explore the road of low-carbon development [6/11/2024]
- In the process of deep integration into the global industrial chain, China's textile enterprises actively explore the road to low-carbon development. According to the data released by the China Textile Industry Federation, as of May 30, 23 brand enterprises and 42 manufacturing enterprises have joined the "China Fashion Brand Climate Innovation Carbon Neutral Acceleration Plan" to jointly promote the textile industry to achieve the "double carbon" goal.Textile industry is an important livelihood industry. As the world's largest textile and garment producer and exporter, China's chemical fiber, yarn, cloth and other output has ranked first in the world. In 2022, the total amount of fiber processing in China's textile industry will exceed 60 million tons, accounting for more than half of the global proportion; Textile and garment exports totaled 340.95 billion US dollars, accounting for more than one third of the world's total. At the same time, the textile industry is also environmentally sensitive. In the process of production and processing, spinning, weaving, printing and dyeing, clothing, and finishing involve equipment energy consumption, material treatment, waste emissions, etc., which will produce carbon emissions.In recent years, the relevant departments have issued a series of policies to promote the green development of the textile industry, and the China Textile Industry Federation has actively promoted the action of industry enterprises and industrial clusters. Many companies are continuing to make green changes, with 83 percent of those participating in the China Fashion Brand Climate Innovation Carbon Neutral Acceleration Program setting climate targets. However, it is also necessary to see that textile enterprises have not completely got rid of the status quo of high energy consumption and high emissions, and the annual emissions of greenhouse gases in China's textile and garment industry are about 230 million tons. Therefore, we should attach great importance to the green development of the industry, and effectively take effective measures to enhance the "green content" of the textile industry from multiple aspects such as technology, supply chain and market.Promoting innovation in green and low-carbon technologies. Science and technology are the primary productive forces, and green technology innovation contains high growth and strong empowerment. It is necessary to promote technological progress in the textile field, increase the research and development and promotion of green and low-carbon technologies, improve relevant systems and mechanisms, pay close attention to the deployment of cutting-edge and key technology research, promote the realization of major breakthroughs, and empower green with digital intelligence.Build a green and low-carbon supply chain. The textile industry covers raw materials manufacturing, textile manufacturing, clothing production and other links, and the green change of the industry is a long-term cause and systematic project. It is necessary to support leading enterprises in the textile industry to play a leading role in key areas such as supply chain integration and innovative low-carbon management, run the green and low-carbon concept through the whole process of product design, raw material procurement, production, transportation, storage, use, and recycling, accelerate the construction of a unified green product certification and identification system, and promote the green and low-carbon development of the whole chain of the supply chain.Give full play to the power of small and medium-sized enterprises. Individual small and medium-sized enterprises energy resource consumption and greenhouse gas emissions are relatively small, but because of the large number of small and medium-sized enterprises in China, the amount of carbon emissions can not be ignored. Small and medium-sized enterprises are an important force for the high-quality development of the textile industry, and they are also the main force for the textile industry to achieve carbon peak and carbon neutrality. Giving full play to the comprehensive advantages of industry specialized special new enterprises and the positive role of small and medium-sized enterprises in innovation is of great significance for the realization of green transformation and low-carbon development of the industry.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.......
- What are the different uses of polypropylene staple fiber? [6/4/2024]
- What are the different uses of polypropylene staple fiber? The different uses of polypropylene staple fiber are mainly divided into three categories: spinning, filling and non-woven fabric. Today, let's talk about the use and production process of polypropylene staple fiber.Polypropylene staple fiber is spun from polyester staple fiber yarn, called pure polyester yarn; The thread spun from polyester staple fiber is called pure polyester sewing thread. In manufacturing, cotton and staple fibers are mixed and spun in different proportions.Polypropylene staple fiber is mainly filled with short fiber in the form of filler, so it can also be used as home filler and clothing warm materials, such as bedding, cotton clothing, sofa furniture, stuffed toys and so on. This staple fiber is mainly hollow polyester staple fiber. As you can see, it has a wide range of uses. It also plays an important role in many places. There are also common nonwovens that are an extension of short fiber applications and have developed rapidly in recent years. And non-woven fabrics are widely used. Such as spunlaced non-woven fabric is mainly used in wet wipes, medical and other fields, geotextile, leather base cloth, linoleum base cloth is mainly used in the engineering field.After understanding the use of polypropylene staple fiber, let's take a look at its process flow. In fact, polypropylene staple fiber is made of PTA and MEG as raw materials. After the polyester melt is formed, it is directly spun and cut to produce short fibers without the need to produce polyester slices. This also needs to be mastered in the production process. It is also because the process is integrated production, the single-line production capacity is large, and the unit processing cost is slightly lower than that of intermittent spinning. Therefore, in fact, the domestic conventional staple fiber production is also basically using melt direct spinning. Technology. Polypropylene staple fiber improves the crack resistance and aging resistance of the external wall putty: the crack resistance of polypropylene staple fiber is much greater than that of wood fiber. Its packaging details are each 20KG woven bag, there are 20 plastic bags, each bag 1KG. In the future, everyone should meet these basic needs when buying. The amount of addition is generally 1 kg, and special requirements are appropriately increased; The addition amount of ready-mixed mortar is 0.9 ~ 1.8kg/m3, and the general addition amount is 1.2kg/m3. At this time, the amount of plastering mortar can be added. 0.6~1.8kg/m3.Jiangsu Haibang New Material Co., LTD., formerly known as Taizhou Hailun Chemical Fiber Co., LTD., is a technology-based chemical fiber enterprise specializing in research and development, production and sales of polypropylene staple fiber. The company has two factories in Taizhou, Jiangsu Province (18 kilometers apart), covering a total area of more than 100,000 square meters, plant 50,000 square meters, office building more than 10,000 square meters.

- Save fabric with the right technology, software and equipment [6/4/2024]
- Fabric consumption has a significant impact on the environmental footprint of fashion manufacturers. For most production modes, the CO2 emissions generated by fabrics account for more than 90% of the entire cutting room life cycle. When it comes to textile waste in the fashion industry, our first reaction may not be the fabric scraps from the clothing production process, but these scraps actually account for 10% to 15% of the total fabric consumption.For manufacturers looking to reduce fabric waste to reduce their environmental footprint, every millimeter of fabric savings is critical. For example, significant fabric savings can be achieved by reducing the gaps between cuts and optimizing the layout (layout) of these cuts on the textile.For mass production, even a slight increase in the proportion of cloth used represents less waste. Therefore, it is critical to use the right technology, software and equipment throughout the workflow to save fabric.In the production preparation stage, artificial intelligence technology can be applied to optimize the cutting and scheduling. Fashion companies using automated scheduling software can not only reduce the amount of fabric used, but also accurately estimate the amount of fabric needed before production, thereby avoiding overstock and fabric shortages. Advances in digital technology have also made it possible to facilitate remote collaboration through 3D prototyping, avoiding unnecessary fabric consumption and transportation.During the cutting process, the same software can be used to reduce or even eliminate the required gaps between cuts.State-of-the-art cutting equipment also plays a key role in saving fabric. Manufacturers can use its various functions to reduce fabric waste. By integrating scanners and advanced image sensors, cutting equipment simplifies the management of patterns on printed fabrics and predicts possible deformations of the fabric, thereby optimizing cutting and reducing waste.Finally, by adapting all ply thicknesses (i.e. layers of pieces to be cut), cutting equipment can more easily adjust production volumes to fluctuations in market demand and order volumes.Declaration: The content of this article is organized from the Internet, and the copyright belongs to the original author; If there is infringement, please inform in time and contact to delete.......
