Polypropylene staple fiber  USES: non-woven fabric for health, needle-punched carpet, needLE-punched non-woven fabric, automotive interior cloth, GEOtextile, filter cloth, garment INTERlining, filter yarn, electric blanket and other fields, can also be mixed with cotton, man-made fiber.

Polypropylene staple fiber features: polypropylene staple fiber density is small, light, can float on the water; Polypropylene colored yarn has high strength and strong tensile resistance. Polypropylene short fiber has a certain acid and alkali corrosion resistance, even if immersed in the sea water do not worry about; Its hygroscopicity is small, almost no hygroscopicity; Polypropylene staple fiber is environmental protection and pollution-free products.

Polypropylene staple fiber  is made of polypropylene through melting, drafting, spinning, cutting and other processes. In THE PROCESS OF MAKING POLYPROPYLENE STAPLE FIBER, WE can add FUNCTIONAL MASTERbatch as required, such as anti-AGING MASTERbatch, flame retardant MASTERbatch, etc., to increase the performance OF POLYPROPYLENE staple fiber. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used for making felt and used as filter material.

Polypropylene staple fiber production equipment introduction:

Most of THE PRODUCTION equipment of polypropylene staple fiber comes from foreign countries, including 7KT/A polypropylene staple fiber equipment introduced from Italy, including a large ring blow spinning head eight-bit spinning machine and a processing line from stretching to packaging.

The inner ring blowing cooling forming process is suitable for high-density porous spinning. The distance between the ring blowing outlet and the spinneret can be adjusted between 5-25mm. Fast wind speed, good cooling effect, suitable for spinning coarse, fine denier country specifications fiber; The production efficiency is high, but the wind speed of the inner and outer layers of the wire is different, and the cooling forming is uneven. General Electric programmable controller is used to monitor, adjust, store and on-line the process parameters. After the device is put into operation, the following technical changes are made :① the bolt pretension is adjusted gradually with the temperature rise, and the leakage problem of melt filter is solved; (2) Change the mixing speed of the oil agent, increase the liquid level of the oil pan, change the silk bundle and the oil roller into reverse motion, adjust the clearance of the crimped rod, and add the oil agent circulation system. The oil content of the fiber reaches 0.7%-1.2%, and the oil consumption is less than 18kg/t. ③ The domestic polypropylene fiber oil PPS-2 is developed, and its performance is better than BK2011 made by Henkel. ④ The cutter head of the cutting machine is improved; ⑤ the pneumatic box transfer system of the baler is improved to ensure that the box transfer is in place once. In addition to the production of 17Dtex carpet yarn, 17-25dtex ×150mm, 5-9dtex×58mm, 8-13dtex ×75mm semi-worded polypropylene yarn, non-woven polypropylene yarn, 1.7-2.8 Dtex ×36.5mm high strength and low extension cotton yarn, and non-woven polypropylene yarn were also developed.
