摘要：
In order to meet the special requirements of polyamide/cotton blended fabrics for outdoor sports end-uses, the blended fabrics were coated with fluorine-free water-repellent agent (CWR-9A), and an adhesive was added to further improve the adhesion fastness between the water-repellent and the fabric. The effect of water-repellent mass concentration, baking time, baking temperature, adhesive type, different volume ratios of adhesives and CWR-9A, washing times were studied on water-repellent treated fabrics. For the polyamide/cotton blended fabrics, the optimal water-repellent finishing process is 120 g/L CWR-9A, temperature at 170 ℃, baking time duration 90 s, and the volume ratio of BD-01 to CWR-9A is 1: 20. The surface structure and morphology of the water-repellent agent and treated fabric were characterized, and the contact angle and water-repellent grade of the treated fabric were measured. The results indicate that adhesion fastness between polyamide/cotton blended fabrics treated with adhesive BD-01 and water repellent CWR-9A is significantly improved. The maximum contact angle is 138°, and the water-repellent grade reaches level 5. © 2021, Periodical Agency of Journal of Textile Research. All right reserved.
