贴衬织物类型对纺织品色牢度评定结果的影响

Effect of adjacent fabrics types on the assessment result of textiles color fastness

中国纺织品色牢度标准规定可任意选择两类贴衬织物中的一类,即单纤维贴衬织物和多纤维贴衬织物.试验证明贴衬织物类型对纺织品色牢度评定结果影响很大,甚至可影响到色牢度合格与否的判定.建议产品标准中标明使用的贴衬类型及其对应的指标.印花织物的取样部位对测试结果影响很大,色牢度较差的某颜色花位与多纤维贴衬中不同纤维条接触,得出的沾色结果亦不同.建议印花织物色牢度测试使用单纤维贴衬织物.

China Standard for textiles color fastness regulated that either of the two adjacent fabrics could be chosen, i.e. single fiber adjacent fabric and multi-fibers adjacent fabric. The tests confirmed that adjacent fabrics types had great effect on the assessment result of textiles color fastness, which even could affect the determinant of color fastness being qualified or not. It was suggested that adjacent fabrics types and corresponding indexes be indicated in the product standard. The sampling position of printed fabric had huge effect on the test result. The pattern with poor color fastness contacted with different fibers in multi-fiber adjacent fabric, which resulted in different staining result. It was proposed that single fiber adjacent fabric be used in color fastness test.
