Embodiment 1

[0021] like figure 1 As shown, the preparation method of the high-comfort triangular hollow microporous polyester fiber described in this embodiment, the steps are as follows:

[0022] The first step, preparation of masterbatch and polyester melt: polymerize sodium isophthalic acid sulfonate with terephthalic acid and ethylene glycol, and the resulting product is a microporous masterbatch, in which isophthalic acid sulfonate The sodium content is 25%; purified terephthalic acid (PTA) and ethylene glycol (EG) undergo esterification, precondensation, and final polymerization to obtain a polyester melt, wherein the esterification temperature is 270°C, and the precondensation temperature is 289°C , the final polycondensation temperature is 289°C, and the obtained polyester melt viscosity is 0.625dl / g;

[0023] The second step is the preparation of hollow microporous polyester fibers with triangular cross-section: the masterbatch is dried by the masterbatch dryer 1, extruded and m...

Abstract

The invention discloses a method for preparing a new type of polyester fiber, especially a method for preparing a hollow microporous polyester fiber with a triangular section with high comfort; The preparation method of the high-comfort triangular hollow microporous fiber with the advantages of moisture removal performance, light weight, better warmth retention, easy washing, and quick drying; the preparation method of the high-comfort triangular hollow microporous polyester fiber obtained in the present invention adopts online metering Adding technology and then adopting melt spinning process, using three symmetrical "V"-shaped spinnerets as spinnerets to obtain fibers, and then performing alkali reduction treatment to obtain high-comfort hollow microporous polyester fibers with triangular cross-section; the fiber fabric It has the advantages of dry and cool, sweat-absorbing and moisture-wicking, easy to wash, fast drying, light weight, and warm.

Description

technical field [0001] The invention relates to a novel preparation method of polyester fiber, in particular to a preparation method of hollow microporous polyester fiber with triangular section and high comfort. Background technique [0002] At present, the fibers on the market mainly obtain the performance of moisture absorption and quick drying through three ways. One is to form a hollow microporous structure. Porous can absorb sweat into the hollow part for storage, or use the body temperature to evaporate the sweat stored in the hollow part, and then discharge the fabric through these micropores; the sweat absorption speed of this fiber fabric is 1.3 times that of cotton fabric, far better than ordinary fabrics polyester fabric; the second is to apply a kind of silk protein with high hygroscopicity on the water-absorbing fiber to obtain better hygroscopicity; the third is to use a special spinning process to make the inner and outer walls of the fiber have elongated gr...
