浅析预处理方法对含胶织物纤维含量分析结果的影响

The Effect of Pretreatment on the Fiber Content Analysis for the Fabric with Adhesive

纤维含量是纺织品的一项重要指标,因此,对于混纺织物,尤其是含有胶或涂层的织物,纤维含量分析的准确性就显得非常重要。以含胶的涤棉混纺织物为例,按照GB/T 2910.11—2009《纺织品定量化学分析第11部分:纤维素纤维与聚酯纤维的混合物(硫酸法)》对其进行纤维含量分析,在此过程中,胶会部分地溶于硫酸当中,从而导致测试出来的纤维含量不准确。所以,在进行纤维含量分析之前对含胶面料进行预处理,也就是去胶,是非常必要的。本课题通过对比实验,分析了不同的预处理方案对含胶的涤棉混纺织物纤维含量分析结果的影响。

Fiber content is an important index of textiles,therefore,the accuracy of fiber content for blended fabric is very significant,especial for coated fabric.As an example,we conduct fiber content analysis on polyester/cotton blended fabric with adhesive according to GB/T 2910—2009 Textiles-Quantitative Chemical Analysis-Part 11：Mixtures of Cellulose and Polyester Fibers（method using sulfuric acid）.However,adhesive will be solved by sulfuric acid solution partly,which result in the inaccuracy of fiber content test result.Hence,it is necessary to do pre-treatment for fabric with adhesive before fiber content analysis.In this article,it analyzes the difference of fiber content test results with different methods of pretreatment.
