Embodiment 1

[0033] After drying the ethylene terephthalate slices, use e.g. figure 1 The special-shaped spinneret shown in the Japanese ABE Engineering Co twin-screw spinning machine and Barmag 3010 stretching machine, the control screw temperature is 290 ° C, the winding speed is 1000 m / min, the cooling air temperature is 27 ° C, and the draw ratio is 3.5 times , to produce special-shaped hollow fibers. The fineness, breaking strength and elongation at break of the obtained fibers are shown in No. 1 in Table 1. The water retention rate of the obtained fiber and the alkali weight reduction rate and water retention rate obtained after alkali reduction treatment at 95°C for 60 minutes in 10g / l or 20g / l NaOH alkali solution are shown in No. 1 in Table 2 .

Embodiment 2

[0035] After the cationic dye-dyeable copolyester chip whose SIP content of the third monomer is 3 mol% relative to PTA is dried, the special-shaped hollow fiber is obtained by the same method as in Example 1. The fineness, breaking strength and elongation at break of the obtained fibers are shown in No. 2 in Table 1. The water retention rate of the obtained fibers and the alkali weight reduction rate and water retention rate obtained after alkali reduction treatment at 95° C. for 60 minutes in 10 g / l NaOH alkali solution are shown in No. 2 in Table 2.

Embodiment 3

[0037] The content of the third monomer SIP relative to PTA3mol% cationic dye dyeable copolyester chips after drying, using such as figure 2 For the special-shaped spinneret shown, the same method as in Example 1 was used to prepare special-shaped hollow fibers. The fineness, breaking strength and elongation at break of the obtained fibers are shown in No. 3 in Table 1. The water retention rate of the obtained fiber and the alkali weight reduction rate and water retention rate obtained after alkali reduction treatment at 95° C. for 60 minutes in 10 g / l NaOH alkali solution are shown in No. 3 in Table 2.

Abstract

This invention cuts and mixes in different proportion TPA - isophthalic acid 5-sodium sulfonate glycol ester for different triod anode ion. dyes or TPA - isophthalic acid glycol ester for disperse dyes to design modified silk spray plates to spin modified hollow closed cross-section fibers and optimize the alkali process conditions to get high water reserved rate free dyed multifunction copolyester fibers.

Description

technical field [0001] The invention relates to a preparation method of polyester fiber and a used spinneret, in particular to a preparation method of polyester fiber and a used special-shaped spinneret. Background technique [0002] Polyester is a fiber made from polyethylene terephthalate (referred to as polyester or PET, the same below) as raw material after melt spinning. [0003] Polyester has excellent physical and mechanical properties, high elastic modulus, good heat resistance, easy washing and quick drying; physical and mechanical properties have great plasticity, and different processing techniques can be used to produce short fibers that can be blended with cotton, wool, hemp and other natural fibers. A fiber that can also be produced as a filament for weaving or knitting. Therefore, polyester fiber has been developed rapidly all over the world. [0004] However, due to the tight aggregation of polyester molecular chains, high crystallinity and orientation, low...
