Therefore, the moisture-conducting and sweat-releasing functions of the fabric are important to be considered when school students and pupils wear school uniform in production. Natural fibers such as cotton, silk, wool and the like belong to hydrophilic fibers, contain hydrophilic groups and have good moisture absorption performance, but the natural fibers can be stagnated on the surface after absorbing sweat generated by a human body, the moisture release speed is particularly slow, and further, clothes soaked by the sweat can be stuck on the skin, so that a wearer feels uncomfortable; the common polyester fiber fabric can be dried quickly due to the hydrophobic property of the common polyester fiber fabric, so that the effect of quick drying is achieved, but the common polyester fiber fabric is poor in moisture absorption and moisture conductivity, sweat on the surface of the common polyester fiber fabric is not easy to absorb, and the comfort of clothes is further influenced.
In recent years, various single-direction sweat-guiding, comfortable and quick-drying fabric fabrics are developed at home and abroad, and the common characteristics of the fabric fabrics are that the fabric fabrics absorb sweat and quickly transmit and diffuse to the outer layer of the fabric, so that a dry and comfortable microclimate environment inside the clothes is kept, and the clothes do not adhere to the skin and have cool and comfortable feeling in a sweat-showing state.
Chinese patent CN108914444A discloses a dyeing and finishing process of polyester-cover cotton one-way moisture-conducting knitted fabric, which comprises the steps of performing single dyeing of polyester on the polyester-cover cotton knitted fabric in a dyeing machine, then performing dehairing enzyme finishing, and then performing polyester hydrophilic finishing and cotton surface water repellent finishing respectively after the dehairing enzyme finishing. The outer layer of this patent polyester-cover cotton fabric is the dacron, and the nexine is the cotton, through carry out hydrophilic finishing and water repellent finish to the surface fabric, makes it have one-way wet function of leading, but the one-way antibiotic nature of leading wet knitted fabric of polyester-cover cotton of this patent is not good.
Chinese patent CN101949092A discloses a preparation method of a moisture-absorbing sweat-releasing crease-resistant fabric, which comprises the following steps: selecting 60% of combed long stapled cotton and 40% of special-shaped polyester fiber with grooves, and weaving the base fabric on an air jet loom by adopting a twill weave method of warp and weft interweaving; carrying out high-temperature high-pressure dyeing treatment on the prepared base cloth; drying, tentering and shaping at the temperature of 145-150 ℃ at the speed of 30-50 m/min; and soaking the fabric in the mixed finishing liquid, and then drying, tentering and shaping to obtain the moisture-absorbing, sweat-releasing and crease-resistant fabric.
