Embodiment Construction

[0025] The PET / PA6 double-component hollow orange segment fiber of the present invention is to use PET monofilament fiber and PA6 monofilament fiber as raw material, and described PET monofilament fiber and PA6 monofilament fiber intertwine to form orange segment fiber, and described orange segment fiber center stays Circular blank, the single fiber fineness of the PET monofilament fiber and PA6 single fiber fiber is 0.1~0.12dtex, the overall fineness of the orange petal fiber is 0.21~0.25dtex, the PET / PA6 double-component hollow orange petal fiber of the present invention passes through Made by the following steps:

[0026] a) Slicing and drying: Slicing and drying PET monofilaments and PA6 monofilaments respectively;

[0027] b) Extrusion: Extrude the sliced ​​and dried PET monofilament fibers and PA6 monofilament fibers by using a screw extruder, the screw speed of which is 30 rpm;

[0028] c) Melting: melting and filtering the extruded PET monofilament fibers and PA6 mono...

Abstract

The invention discloses a PET/PA6 (Polyethylene Terephthalate/Poly Amide 6) double-component hollow orange peel fiber, comprising a PET single-fiber fiber and a PA6 single-fiber fiber, wherein the PET single-fiber fiber and the PA6 single-fiber fiber are mutually wound to form the orange peel fiber; a circular blank is formed at the center of the orange peel fiber; the single-fiber finenesses of the PET single-fiber fiber and the PA6 single-fiber fiber are 0.08-0.13 dtex; and the whole fineness of the orange peel fiber is 0.18-0.28 dtex. The invention further discloses a production process of the PET/PA6 double-component hollow orange peel fiber. A double-component spun-bond composite spinning technology is adopted and the PET single-fiber fiber and the PA6 single-fiber fiber are used as raw materials; a structural design of a multi-layer step spinning plate is adopted and a multi-channel low induced draft controllable uniform net forming technology and a fiber surface splitting and hydroentangle reinforcing integrated technology are adopted, so that the production cost is reduced, the process flow is shortened, the production speed and the formation rate are improved; and a product with small fiber diameter, high strength, good tear resistance and abrasion resistance, and difficulty of dropping chips in a use process is produced.

Description

【Technical field】 [0001] The invention relates to a superfine fiber and a production process thereof, in particular to a PET / PA6 double-component hollow orange segment fiber and a production process thereof. 【Background technique】 [0002] Fiber is the most basic raw material for nonwoven materials. With the continuous improvement of production technology and people's living standards, the consumer market has put forward higher demands on the performance of textiles. In order to meet these demands, the market has developed functional fibers, high Sensitive fibers, smart fibers, degradable fibers, bi-component fibers, etc. Among them, bi-component fibers have the best quality and the largest market for their products. In the current market, the processing methods for bi-component fibers mainly include electrospinning, melt-blowing and the combination of composite fiber / fiber opening. The electrospinning method can make the fiber reach the nanometer level, but the processing ...
