Abstract

The invention relates to a preparation method of a comfortable copolyester fiber, and belongs to the technical field of modified polyester spinning. The preparation method comprises the following steps: 1) mixing an organic conductive mica nano powder, conductive potassium titanate nano whiskers, sodium acrylate, ethylene glycol, butylene glycol, p-hydroxybenzoic acid and sodium germanate to prepare a comfortable compound alcohol solution; 2) mixing organic sodium based bentonite, sodium alginate, diatomite, polyethylene glycol, butylene glycol, an antioxidant 1010, lauroyl diethanolamide, antimony ethylene glycol and a protonation agent phosphoric acid to prepare a comfortable composite accelerant; and 3) carrying out copolycondensation of the comfortable composite multifunctional alcohol solution and the comfortable compound accelerant with purified terephthalic acid and ethylene glycol to prepare comfortable copolyester, spraying a melt with an H-shaped combined spinneret hole, expanding and bonding, and thus obtaining the comfortable copolyester fiber. With the spinneret hole having an H-shaped fiber cross section structure, the fiber surface is provided with an opening guide hole, the fabric is breathable and permeable to moisture, the fiber comfort is further strengthened, and the comfortable copolyester fiber has the moisture-absorption and sweat-releasing functions and good antistatic performance.

Description

technical field [0001] The invention relates to the technical field of modified polyester spinning, in particular to a method for manufacturing comfortable copolyester fibers. Background technique [0002] Polyester fiber is an important variety of synthetic fibers, with good wearability, polyester itself does not have hydrophilic groups, poor hygroscopicity, poor air permeability and moisture permeability, and the static electricity generated by its fabric friction cannot be eliminated in time, so that Polyester fiber is not comfortable to wear. [0003] In order to solve this problem, there are two main research methods for moisture-absorbing and sweat-wicking fibers. One is to use the capillary action of ultra-fine fibers to quickly discharge sweat to the surface of the clothes, and the other is to use special-shaped cross-sections to discharge sweat through capillary phenomena. ; Polyester antistatic fiber has been developed from surface coating antistatic, temporary an...
