Z/(n)模n剩余类环的构造

本文先讨论了Ｚ／（ｐｍ）环的结构，如其幂零元、幂等元、可逆元、零因子和理想的结构和数量．然后，利用同构知识得到了Ｚ／（ｐ１ｍ１ｐ２ｍ２…ｐｔｍｔ）环的结构，即其幂零元、幂等元、可逆元、零因子和理想的结构和数量．     

用多羧酸作整理剂的无甲醛整理

本文综述了利用多羧酸作为整理剂对织物进行无甲醛整理的发展过程,酯化和交联反应的机理以及BTCA作为酯化剂,NaH_2PO_2作为催化剂的整理工艺,评价了应用较廉价的其他多羧酸和催化体系对BTCA和碱金属磷酸盐类整理体系的替代,介绍了无甲醛整理剂在非纤维素纤维织物上的应用前景。     

Cationic Modification of Cellulosic Fibres with Polyepichloro-hydrinamine Resins to Offer a Potential Dyeing Process Producing Cleaner Dyeing Effluent

Cationic modifying agent (PECH-amine) with lower molecular weight and containing less nitrogen was prepared and characterized. The water-soluble cationic modification agent has high reactivity for cotton. Cotton modified by this agent can be dyed under salt-free and neutral conditions with direct and reactive dyes. Dyes in the dyebath could be completely exhausted and a dyeing effluent without residual dyes and salt could be expected.
