GB/T 5711-2015Textiles -- Tests for colour fastness -- Colour fastness to dry cleaning using perchloroethylene solvent (English PDF)

1 Scope

1.1 This Standard specifies the method for determination of textiles colour fastness to drycleaning using perchloroethylene solvent.

1.2 This Standard is not applicable to assess the durability of textile finishing; neither is it applicable to assess stain-removing operation capability of textile colour to dry- clean shop.

1.3 This test only contains the test for colour fastness to drycleaning; if the assessment of other drycleaning aspects is required, such as water spots, solvent spots, steam press and iron, and etc., then other test methods shall be provided.

1.4 For certain textile materials, if the dry cleaning agent contains washing liquid or water, it may change the performance of colour fastness to drycleaning. This test is required to be conducted in case the fabric is in dry state; use the container without any moisture, only use the dry cleaning agent to test.

1.5 If there is no further instruction, the colour fastness to drycleaning in this Standard indicates that in the perchloroethylene solvent. However, if required, other types of solvent can also be used.

3 Principle

Paste the textile specimen to the adjacent fabric, put them together with stainless steel sheet into the perchloroethylene to stir; then extrude, centrifuge, remove liquid and dry the specimen and adjacent fabric. Take the original sample as the reference sample, use gray scale or instrument to assess the change in colour of specimen and the staining of the adjacent fabric.

4 Safety Warning

Perchloroethylene and other solvents are harmful to the human health, so it is very important to operate according to solvent use safety rules. The test is recommended
