摘要:

为满足锦纶/棉混纺织物用于户外运动产品的特殊要求,采用无氟拒水剂CWR-9A对混纺织物进行拒水涂层处理,并选取黏合剂来进一步提高拒水剂与织物间的粘接牢度。探讨了拒水剂质量浓度、焙烘时间、焙烘温度、黏合剂种类、黏合剂与拒水剂体积比、洗涤次数等对混纺织物拒水效果的影响,得到锦纶/棉混纺织物拒水整理最佳工艺:CWR-9A质量浓度为120 g/L,焙烘温度为170 ℃,焙烘时间为90 s,黏合剂BD-01与拒水剂CWR-9A的体积比为1∶20。对整理后织物的表面结构和形貌进行了表征,测定了整理后织物的接触角、拒水等级等。结果表明:黏合剂BD-01的引入可显著提高无氟拒水剂与混纺织物的粘接牢度,其接触角最高为138°,拒水等级最高达到5级。

Abstract:

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.

Key words: fluorine-free water-repellent agent, polyamide/cotton blended fabric, adhesive, water repellent finishing, adhesion fastness
