Analysis of quantitative method of fiber content of polyester/spandex fiber blended fabric
Various kinds of polyester/spandexfiber blended fabrics were quantitatively analyzed by the splitting method,75％sul-furic acid method,80％sulfuric acid method,dimethylformamide method and dimethylacetamide method.Through the compari-son and analysis of the results,it can be seen that the splitting method is the most accurate,but some fabrics may not be separated,which has certain limitations.The dimethylformamide method is suitable for light colored fabrics,and dark fabrics may cause the spandex value to be too large.The most commonly used quantitative method is 75％sulfuric acid method,which is efficient and has high data accuracy.
