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.
