3. Thin water is changed to continuous water, and
small fabric test piece is changed from the west side to the short side. If necessary, it shall be specified separately. 5. The combination of multi-fiber pasting and single fiber pasting is added. This standard replaces the small and medium method B8921-83 from the date of implementation. 3. This standard is proposed by the China Textile General Association.
This standard is proposed by the China Textile General Association! The Standardization Institute of China National Textile and Apparel Council, Shanghai Textile Standards Institute, Tuhai Textile Science and Technology Research Institute are responsible for drafting, and Shanghai Silk Science and Technology Research Institute is responsible for co-drafting. The main contributors of this standard are Qi Zhimin, Xu Jie, Lu Anbao, Shi Ming, and Hu Minmin. This standard was first issued in 1933. This standard is entrusted to the Standardization Institute of China National Textile and Apparel Council for interpretation. G#/T3921.3—1997 ISO Foreword ISO (International Organization for Standardization) is an international alliance of national standards organizations (ISO members). The preparation of international standards is usually carried out by ISO technical committees. Members have the right to propose committees if they are interested in items for which technical committees have been established. Official and unofficial international organizations have established contacts with ISO and may work with ISO. ISO is closely connected with the International Electrotechnical Commission (IEC) in all matters related to electrotechnical standardization. The draft international standards prepared by the ISO/TC3B Technical Committee are passed on to members, and more than 75% of them are published as international standards. International Standard 190105-C03 was developed by ISO/TC3B Technical Committee. This fourth edition is a technical revision of the second edition and replaces the third edition (1SC105-C.031987). 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 1SC105-C.031987) 105-c03:1989

This standard specifies the third test in a series of five color fastness tests and has been developed to supplement the test method for color fastness to washing of colored fine fabrics. This series of tests includes the following and the test of the washing operation range. Note that this method is only formulated to measure the effect of washing on the color fastness of fabrics and does not reflect the results of all washing operations. 2 Applicable standards
The provisions contained in the following standards will become the provisions of this standard when they are cited in this standard. The version of this standard is valid. All standards will be revised. Parties using this standard should explore the possibility of using the new version of the following standards. GB250-1955 Assessment of color change Use gray sample card (idt150105-402, 1993) GB251-1595 gray sample for evaluating color fastness (i[S]115A31993) GB/T6151-1097 General rules for color fastness test of nano fabrics (eq1S)105-A011594) GB7564~7566--87 Standard test for color fastness of products (ncgIS ()105-F: 1985) CB11404-89 Fabric color test fiber adhesive fabric specification 0g1501C5-F10: 19893 Processing
The nano fabric sample is combined with one or two pieces of specified paper, placed in soap, and stirred under the specified time and temperature conditions, and then washed. Wash and dry. Use the grey scale to evaluate the discoloration of the sample and the staining of the lining: 4 Equipment and reagents
4.1 Suitable mechanical equipment (Appendix A) consists of a water-swimming worm with a rotating shaft, which supports a number of stainless steel containers with a capacity of 550mL±50mL, with a diameter of 75mm±5mm and a height of 125mm±10mm. The distance from the axis to the bottom of the container is 45m±10mm, and the rotation speed of the shaft and container is 40r/min±21/min. The water temperature is automatically controlled. The test solution is maintained at 60±2°C.
