Study on qualitative and quantitative analysis methods for diacetate fiber and triacetate fiber
In response to the problems of high reagent toxicity and long testing time in the qualitative and quantitative analysis of diacetate fiber and triacetate fiber at present,this paper designs a comparative experiment on the dissolution effect of different ace-tic acid concentration reagents and the optimal acetic acid concentration with commonly used identification reagents.The results indicate that 75％acetic acid can be applied for qualitative and quantitative analysis of diacetate fibers and triacetate fibers.This reagent has low toxicity and short dissolution time,thereby improving testing efficiency.
