What are the problems in the production process of polypropylene staple fiber?The production process of polypropylene staple fiber seems simple and convenient, but in fact, if the operation is slightly wrong, it will have a great impact on the production of the finished product, such as the problem of excessive elongation of polypropylene staple fiber.Polypropylene staple fiber elongation is too large, will bring a lot of harm. And in blending, the yarn strength will also be affected.In the spinning process, it has been found that the yarn strength difference after blending, such as the qualit......[ Read More ]
Green and sustainable development and carbon emission reduction have become a global consensus. It is the trend of The Times and a systematic project, which requires rational design and systematic layout based on the overall situation. As far as the development of new products is concerned, first of all, it is necessary to get rid of the traditional thinking, implement the concept of sustainable development in the design stage, and strive to achieve the sustainable development of products from the selection of raw materials to the final recycling, and then proceed with the design and productio......[ Read More ]
Polypropylene staple fiber is made of polypropylene as raw material through melting, drafting, spinning and cutting. In the process of making PP staple fiber can be added according to the need of functional masterbatch, such as anti-aging masterbatch, flame retardant masterbatch and so on to increase the performance of PP staple fiber. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used for the manufacture of felt, used for filter materials.Polypropylene staple fiber characteristics: polypropylene staple fiber density is small, light, can float on the water; Poly......[ Read More ]
Polypropylene staple fiber to the specification of natural fiber, pp staple fiber can be divided into cotton, wool, carpet and medium length staple fiber. They can be spun pure or blended with different proportions of natural fibers or other fibers to make strips, fabrics and felts. For example, the general grade asphalt carbon fiber was cut into 150mm length, 15μm diameter, 800MPa strength, 41GPa modulus of carbon fiber, and phenolic carbon fiber (length 70mm, 200MPa strength, 14μm diameter) in a ratio of 8:2, to produce stable and uniform yarn. Woven into a variety of shapes of fabric or cut......[ Read More ]
Prices continue to decline, polyester enterprise stock appreciation dividend since may disappear, and rapid depreciation pressure, and low production and sales, polyester inventory rapidly accumulating, industry inventory back to a month or more high level, the second half will have to increase price promotions, filament prices quickly fell one thousand yuan of above.High inventory of polyester enterprises, especially leading enterprises, increase pressure to reduce production again. Polyester end is under pressure, some polyester factories again to reduce production to solve their own high in......[ Read More ]

Polypropylene staple fiberwith polypropylene resin as the main raw material, after melting spinning, drafting, crimping, drying shaping cut off, packaging and other processes of color and colorless, regulated number and length of the fluffy fiber. So polypropylene staple fiber can be used in what fields?1. Used in paper industryThe application of polypropylene staple fiber in dry papermaking is mainly to produce expanded soft paper. Expanded soft paper, also known as dust-free paper, is a new disposable sanitary material, which can be made into high-density dust-free paper absorption core mate......[ Read More ]
On June 9th, in the main control room of the pilot test base of the National Advanced Functional Fiber Innovation Center, Xu Yonghua, an engineer sitting in front of the screen, reported the operation status of the equipment through the walkie-talkie. The final stage of the joint test is expected to be officially put into use by the end of June.The National Advanced Functional Fiber Innovation Center is the 13th and the first national-level innovation center led by a private enterprise in the country. . At present, a technical innovation supply system supported by key laboratories, pilot bases......[ Read More ]
The spinning process of ultra-fine polypropylene staple fiber should be determined according to the raw material. The length of the raw material used for spinning of ultra-fine polypropylene staple fiber is cotton, so cotton spinning system is used for spinning. When processing polypropylene staple fibers, it is easy to generate static electricity and cause sticking. It can be suitable for wetting and oiling during mixing to reduce the friction factor of the fiber surface. Effective anti-sticking measures should be adopted, and the cleaning process should reduc......[ Read More ]
