AI Technical Summary

Technical Problem

The prior art is difficult to achieve synergistic optimization of moisture absorption and sweating and antistatic properties on polyester fiber fabrics, and traditional methods have problems such as unstable performance or affecting the feel.

Method used

By introducing ether bonds and quaternary ammonium ions into the polyester fibers, PET is modified by transesterification reaction to form a covalent bonded modified hygroscopic antistatic copolyester, combining ether bonds with water molecules to form a hydrogen bond network and quaternary ammonium ion charge conduction, achieving improvements in hygroscopic and antistatic properties.

Benefits of technology

The modified fabric still maintains efficient moisture absorption and sweating and antistatic properties after multiple washings, solving the problem of unstable performance in traditional methods and achieving long-term functional improvement.

Abstract

The invention relates to a fabric with moisture absorption, sweat releasing and antistatic functions and a preparation method thereof, and belongs to the technical field of textiles. According to the invention, terephthalic acid, ethylene glycol, a catalyst and a self-made antistatic monomer are used as raw materials to prepare the fabric with moisture absorption, sweat releasing and antistatic functions, PET is modified through ester exchange, and the synergistic effect of ether bonds and quaternary ammonium salt ions is introduced into a side chain, so that the moisture absorption and antistatic properties are improved; ether bonds and water molecules can form a hydrogen bond network to lock free water molecules, quaternary ammonium salt ions can provide carriers for ionization, qualitative conduction is carried out under the action of an electric field, so that static accumulation is eliminated, a lasting antistatic effect is achieved, and the material has moisture absorption and antistatic properties; in addition, ether bonds and quaternary ammonium salt ions are stably connected to a PET molecular side chain through covalent bonds, and the modified fabric with the moisture absorption, sweat releasing and antistatic functions can still keep efficient activity after being washed for multiple times.
