摘要
以直链淀粉质量分数较高的豌豆淀粉为原料,在碱性条件下以一氯乙酸为醚化剂,制备了羧甲基豌豆淀粉(CMPS)浆料,对浆液黏度、浆膜性能和浆纱性能进行了研究。结果表明:随着取代度的增加,羧甲基豌豆淀粉的浆液黏度逐渐降低,黏度热稳定性逐步增加。CMPS浆膜水溶性、耐磨性和吸湿性好,采用CMPS浆纱可显著提高浆纱的力学性能。
Carboxymethylated modified pea starch is synthesized under alkaline conditions from pea starch and etherifying agent(chloroacetic acid).Its sizing viscosity,sizing film properties and yarn sizing performances are studied.The results show that the viscosity of CMPS decrease and its heat stabilization increase with the in⁃crease of degree of substitution(DS).Water-solubility,abrasion resistance and hygroscopic property of sizing film are good.The mechanical properties of CMPS sized yarns are significantly improved.
