摘要
为解决天然羽毛蛋白在中性条件下水溶性较差而导致其在纺织上浆领域内使用受限的问题,通过将不同质量浓度的亲水性乙烯基单体丙烯酸接枝到天然羽毛蛋白的分子链上,制备出一系列具有不同接枝率且在中性条件下可溶于水或较好地分散于水的羽毛蛋白-丙烯酸接枝共聚物浆料。分别采用天然羽毛蛋白与接枝改性羽毛蛋白对纯棉经纱进行了上浆实验,测试了上浆纱的强伸性、耐磨性及毛羽数量。结果表明,对羽毛蛋白进行接枝改性可显著提高其浆纱性能,与纯棉原纱相比,当选择接枝率为29.72%的羽毛蛋白-丙烯酸接枝共聚物作为上浆材料时,上浆纱的强度提高了24.56%,断裂伸长率仅降低了14.49%,耐磨次数达到原纱的4倍,毛羽数量亦大为降低。
In order to solve the problem of natural feather keratin on limited use in the textile sizing field due to poor water-solubility under neutral condition,various concentrations of hydrophilic vinyl monomeracrylic acid（ AA） were grafted onto the molecular chains of nature feather keratin. A series of feather keratin-g-PAA with different grafting ratios were prepared and the grafted feather keratin sizes were endowed with water-solubility or good water-dispersibility under neutral condition. The sizing experiments on pure cotton yarns were carried out using the natural and grafted feather keratins as sizing agents,respectively. Sizing properties of feather keratin were evaluated in terms of tensile strength,tensile elongation,abrasion resistance,and the hairiness amount of the sized yarns. The results show that graft modification can remarkably improve sizing properties of feather keratin. Compared with the unsized cotton yarns, the yarns sized by modified feather keratin（ grafting ratio 29. 72%） exhibit better properties. The tensile strength of the yarns sized by the grafted keratin is increased by 24. 56% while the tensile elongation is decreased by only 14. 49%. The abrasion number of the sized yarns is almost 4 times as high as that of unsized yarns. In addition,the hairiness amount of the yarns sized by the grafted keratin is decreased to a large extent.
