Discussion on quantitative analysis method of acetate fiber/polyester fiber blended fabric
Formic acid/zinc chloride method,N,N-dimethylformamide method and 75％sulfuric acid method were used to quan-titatively analyze the acetate fiber/polyester fiber blended fabric,and compared with the acetone method of the national standard GB/T 2910.3-2009.The results showed that:75％sulfuric acid method,formic acid/zinc chloride method,N,N-dimethylforma-mide method can be accurate quantitative analysis,and 75％sulfuric acid method is more healthy,economic and safe,it is recom-mended to consider the above three methods in the detection test,the priority of 75％sulfuric acid method.
