This standard specifies the first test in a series of five tests for color fastness to washing and has been established as a test method for color fastness to washing of colored textiles. This series of tests covers a range of washing operations from mild to severe.

This standard is equivalent to 19O105-C01:1989. This standard is one of the five annual test methods for color flow resistance. This standard has made the following revisions to CB3921-83: 1. According to GB/1.11993, the cover and header format have been changed, the front height (i.e. 15 foreword) has been added, 5 standard items and the recommendation of three foreign test instruments have been added, and the synthetic washing column has been listed in the table B. 2. The length unit has been changed to mm.
3. Steam solid water has been changed to blue super base
4. The four sides of the fabric combination sample have been changed to a short chain. If necessary, + and make regulations. 5. Add the use of multi-fiber stickers and single fiber stickers. From the date of implementation of this standard, the method in GB3921-83 has been replaced. 1. This standard is proposed by the China National Textile and Apparel Council.
This standard is under the jurisdiction of the China National Textile and Apparel Council's Standardization Research Institute. The standard was drafted by the China Textile Industry Association, the Shanghai Textile Science and Technology Research Institute, and the Shanghai Institute of Wool and Linen Technology. The main drafters of this standard are Qi Feimin, Xu Jie, Lu Bao, Shi Ting, and Hu Lingyi. This standard was first issued in 1983 and was commissioned by the China Textile Industry Association's Institute of Chemical Engineering to draft it. GR/T 3921.1—.1997 ISO is an international organization of standards organizations (ISO) that coordinates the preparation of international environmental standards. [Work is completed by the technical committee: Each member has the right to participate in the committee if they are interested in the items established by the technical committee.

technical standard specifies one of the five washing fastness test questions in the series, which has become a convenient test method for studying the washing fastness of colored fabrics. This series of tests covers a wide range of washing operations from relatively strong to relatively strong, and this method does not determine the actual results of the fabric's bleaching resistance. 2 Reference standards

The product sample is placed in an electrolytic solution with one or two standard fabrics, and then washed and dried under the specified time and temperature. The sample is evaluated for color change and adhesion. 4 Equipment and reagents 1. Suitable mechanical equipment (see Appendix A), a water bath consisting of a rotating shaft: the actual rotating shaft is a 50L-50L glass or stainless steel device, with a true diameter of 5m5m. 12m! 10m and a distance from the center of the lifting part of 15nm: 1cm: the rotation speed of the auxiliary device is 40r/min ± 2r/mn, and the water bath temperature is controlled by a thermostat to keep the tube at a constant temperature of 40℃ ± 2C. 4.2 Soap, with a water content not exceeding 5, and meeting the following requirements (maximum): Free alkali (calculated as N) Free sodium (calculated as N) Total fat content Fat-free soap (calculated as N) Total fat content (calculated as N) Fat-free soap (calculated as N) Total fat content (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) Fat-free soap (calculated as N) 3921.1-1997
