The principal prupose of this study is on nanosizing the disperse dyestuffs to colourize the fabric made of polyester super-micro fibers and to improve its dyeing properties.

摘要本究主要是以分散性染料染超微细聚酯纤维，以一般粒径染料与细化至奈米粒径染料染较，针对坚牢度测试与上程度来分析。

A novel dust proofing agent for dyestuff was prepared by the addition of industrial fatty acid and glycol epoxide, which could produce a kind of emulsor.

采用工业脂肪酸和环氧乙烷加成法制成乳化剂,进而获得一种新型染料防尘剂。

Extract dyestuffs such as mineral and plant,etc. from the nature, will call as five colors bluely and greenly, yellowly, redly, whitely, blacklily, and then seize other after the five color mixture.

从大自然中萃取矿物与植物等染料，将青、黄、赤、白、黑称为五，再将五混合后攫取其它的颜。
