Embodiment 1

[0021] Such as 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 sulfonate isophthalic acid, terephthalic acid and ethylene glycol, the resulting product is microporous masterbatch, and sodium sulfonate isophthalate The content is 25%; purified terephthalic acid (PTA) and ethylene glycol (EG) undergo esterification, precondensation, and final polymerization to obtain polyester melts. The esterification, precondensation, and final polymerization reactions are as follows According to the existing technology in this field, the esterification temperature is 270°C, the precondensation temperature is 289°C, the final polycondensation temperature is 289°C, and the melt viscosity of the obtained polyester is 0.625dl / g;

Abstract

The invention discloses a preparation method of a novel polyester fiber and particularly relates to the preparation method of a high-comfort triangular hollow microporous fiber which is newly developed and has the advantages of being dry, comfortable, cool and refreshing, capable of absorbing sweat and draining moisture, light, good in warm keeping, easy to clean, fast to dry and the like. According to the preparation method of the high-comfort triangular hollow microporous fiber, the online measurement addition technique and a melt spinning process are adopted, three symmetrical V-shaped spinneret plates serve as spinneret assemblies to obtain the fiber, and an alkali reduction process is performed to obtain the high-comfort triangular hollow microporous fiber. The fiber fabric has the advantages of being dry, comfortable, cool and refreshing, capable of absorbing sweat and draining moisture, easy to clean, fast to dry, light, good in warm keeping and the like.

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...
