| 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 the coating properties of polysulfonamide(PSA)/cotton blend fabric,additives such as carboxymethyl cellulose(CMC) and sodium alginate(ALG) were added into waterborne polyurethane.By comparing the coating properties like moisture permeability,rain drop repellency and bending length,the results showed that CMC was superior to ALG.Addition of polyethylene glycol(PEG) into the CMC-containing waterborne polyurethane could significantly improve the moisture permeability and hand feeling of the coated fabric.It was found that under the conditions of coating agent with CMC 0.25% and PEG 10%,moisture permeability of the coated fabric was up to 6 721.5 g/(m2·24 h),and bending length of the fabric was 5.51 cm,with rain drop repellency rating of 5,indicating it had better waterproof,permeability and hand feeling. |
