Abstract

The invention relates to a preparing method for a unidirectional wet-conduction pure cotton fabric based on nano-zinc oxide. The preparing method includes the steps that (1) nanometer ZnO powder and aphthalic-ester coupling agent are mixed, then Tween-80 is added, dispersion is conducted, and modified nanometer ZnO finishing liquid is obtained; (2) the cotton fabric is soaked into the modified nanometer ZnO finishing liquid, two times of soaking and two times of rolling are conducted, then pre-baking and baking are conducted, and the nanometer-ZnO-finished cotton fabric is obtained; (3) printing net is put on the nanometer-ZnO-finished cotton fabric, slurry is put, slurry is scraped at constant speed, then the fabric is pre-baked, baked, soaped and dried, and the unidirectional wet-conduction pure cotton fabric is obtained. According to the preparing method for the unidirectional wet-conduction pure cotton fabric based on the nano-zinc oxide, through compound function finishing, the fabric has the excellent moisture absorption and nice and cool effect, and the thermal-wet comfort requirement when people are in hot weather and strenuously exercise is met.

Description

technical field [0001] The invention belongs to the technical field of textile functional finishing, in particular to a method for preparing a unidirectional moisture-conducting pure cotton fabric based on nanometer zinc oxide. Background technique [0002] With the continuous improvement of living standards, people are not only satisfied with the simple needs of food, clothing, housing and transportation, but are moving towards higher pursuits such as health and comfort. From the perspective of dressing, we no longer only pursue the good-looking and durable clothing materials, but hope that the clothes have some special functions. Summer is not only the day of sun exposure, but also the season when people sweat profusely. While protecting themselves from ultraviolet rays, people urgently need to wear cool and comfortable clothing. This has just challenged our existing traditional textile fabrics, so fiber fabrics with moisture absorption and coolness have been sought after...
