Composite polypropylene fiber spinning device and preparation method thereof

Abstract

The invention relates to the technical field of polypropylene fibers, in particular to a composite polypropylene fiber spinning device and a process thereof.The device comprises a housing, filter chambers, a strainer, a needle tube, a locking ring, a cone curling drum, a motor and a high-voltage electrostatic generator; the interior of the housing is symmetrically provided with two filter chambersand two inclined through holes, the inclined through holes pass through the filter chambers and through the whole housing, the two sides of the housing are provided with feeding holes, and the strainer is located at the bottoms of the filter chambers; and the needle tube perforates in the inclined through holes and both ends of the needle tube extend outside the housing.The invention has the following benefits: the produced composite polypropylene fibers are allowed to have a high compounding degree; the spinning device in the invention may not only prepare composite polypropylene but also prepare single-component polypropylene fibers; the inclination of the needle tube makes the distance of molten polypropylene flowing outside the housing from the housing is short so that the molten polypropylene may be compositely wound better; and the cone curling drum allows composite polypropylene fibers to be wound better without being scattered outside.

Description

technical field [0001] The invention relates to the technical field of polypropylene fibers, in particular to a composite polypropylene fiber spinning equipment and a preparation method thereof. Background technique [0002] Polypropylene fibers can be divided into long fibers, short fibers, spunbond nonwovens, meltblown nonwovens, etc. Most of the production process of polypropylene staple fiber adopts porous, low-speed, continuous process, that is, short spinning process. Polypropylene staple fiber blended with cotton can be made into acrylic cotton muslin and bed sheets, that is, fiber and viscose blended can be used to make blankets, polypropylene pure spinning and blended wool, polypropylene blankets, carpets, polypropylene cotton wool filters for cigarettes. [0003] Composite polypropylene fiber is the polypropylene fiber obtained by co-spinning polypropylene with different components. It can be known from the publication number CN204982164U "a two-component composit...

AI Technical Summary

Problems solved by technology

[0003] Composite polypropylene fiber is the polypropylene fiber obtained by co-spinning polypropylene with different components. It can be known from the publication number CN204982164U "a two-component composite spinning component with controllable flow rate". The two-component spinning assembly is generally formed by filtering, distributing, and combining the melt into a certain shape, and then extruding from the spinneret hole. The two-component spinning obtained by this spinning assembly generally has a low degree of mixing. Or the spun fibers need to undergo secondary processing
