摘要
以直链淀粉为原料,尿素为酯化剂,采用干法制备了尿素直链淀粉。对其浆液及浆纱性能进行了测试,用其做浆料对纯棉和涤棉原纱进行了上浆试验。结果表明,尿素直链淀粉浆液具有良好的冻融稳定性、透光率及黏度热稳定性,与纯棉和涤棉原纱都具有良好的黏附性,其浆膜具有良好的强伸性和耐磨性。尿素直链淀粉对环境无污染,是一种可替代PVA、用于纯棉和涤棉上浆的良好环保纺织浆料。
This expefimem was on preparating amylose carbamate through dry method by using amylose as raw material and carbamide as esterifying agent. Its slurry and sizing capability were tested, and starching process on pure cotton and polyester/cotton was carried on by using this as sizing agent. The result indicates that amylose carbamate has better properties of easier gelatinization, better freeze - thaw stability and higher clarity than amylase. Its size film shows good stretch and wearability. Amylose carbamate that can replace PVA is a good non - polluting sizing agent for pure cotton and polyester/cotton.
