A superconducting wet-drying yarn, its preparation method and application
High-shrinkage polyester fibers are prepared by using high-shrinkage polyester chips to create a blend with cotton fibers, forming a honeycomb-like water-guiding channel. This solves the problem of the generally poor moisture-wicking and quick-drying performance of traditional yarns, achieving a highly efficient moisture-wicking and quick-drying effect as well as washability.

AI Technical Summary
Technical Problem
Traditional yarns generally have poor moisture-wicking and quick-drying properties, and also suffer from uneven fiber dyeing and reduced spinnability.
Method used
High-shrinkage polyester fibers are prepared by using high-shrinkage polyester chips and blended with cotton fibers to form superconducting wet-drying yarn. Through the molecular forces and structural design between fibers, honeycomb-shaped water-conducting channels are formed to achieve rapid absorption and diffusion of sweat.
Benefits of technology
Superconducting quick-drying yarns and fabrics maintain excellent moisture-wicking properties even after multiple washes, solving the problems of uneven dyeing and spinnability of traditional yarns, and achieving rapid moisture-wicking and quick-drying effects.

Abstract
This invention relates to the field of yarn technology, specifically disclosing a superconducting wet-drying yarn, its preparation method, and its application. The yarn is prepared by blending high-shrinkage polyester fibers and cotton fibers. The preparation of the high-shrinkage polyester fibers includes two parts: raw material synthesis and fiber forming. Terephthalic acid and ethylene glycol are used as raw materials. After the esterification reaction, polyethylene glycol and aromatic dicarboxylic acid ester sulfonate are added, resulting in high-shrinkage polyester chips. These chips are then used as raw materials for spinning to obtain high-shrinkage polyester fibers. Through the two-component design of the yarn, a micro-circulation diffusion system with superconducting moisture absorption and sweat-wicking effect is formed, effectively improving the hygroscopicity of the polyester fibers. Even after multiple washes, it still possesses excellent superconducting wet-drying properties, long-lasting efficacy, and good wash resistance, without causing uneven dyeing or unidirectional moisture wicking problems.
