This Part of GB/T 30159 specifies two test methods, i.e. liquid staining method and solid staining method, for determining the stain resistance of textiles, and provides evaluation indexes of stain resistance.
This Part is applicable to various textile fabrics and their products. According to types and purposes of products, one or two methods may be selected. Test results obtained from different soils and methods are not comparable.
This Part is not applicable to coated fabrics for membrane structures. When the colour of sample is close to the solid soil, solid staining method should not be adopted for the evaluation.
