摘要/Abstract

摘要： 为了改善芳砜纶/棉混纺织物的涂层效果，水性聚氨酯涂层胶中加入添加剂羧甲基纤维（CMC）或海藻酸钠（ALG）；通过对比及分析涂层织物的透湿性、淋雨性和硬挺弯曲长度，添加剂CMC的综合效果优于ALG；在含有CMC涂层胶中加入聚乙二醇（PEG）能显著改善织物的透湿性能以及织物手感；当CMC添加量为0.25%，PEG添加量为10%时，涂层织物的透湿量达到6721.5g/m2.24h，淋雨性为5级，织物弯曲长度为5.51cm，具有较好的防水透湿性能以及织物手感。

Abstract: In order to improve coating properties of Polysulfonamide (PSA)/cotton blend fabric, additives such as carboxymethyl cellulose (CMC) or sodium alginate (ALG) was added into waterborne polyurethane. By comparing and analyzing coating properties such as moisture permeability, water resistance and bending length, CMC was generally superior to ALG in effects. The CMC-containing waterborne polyurethane with adding polyethylene glycol (PEG) could significantly improve moisture permeability and handle of coated fabric. It was found that under the condition of coating agent with 0.25% CMC and 10% PEG, moisture permeability of coated fabrics could be up to 6721.5g/m2.24h, water resistance could be at 5 grade and bending length decreased to be 5.51cm.

Key words: waterborne polyurethane , CMC , ALG , waterproof , moisture permeable
