Foreword
This standard is a revision of GB5713-85 based on ISO105-E01:1994 "Textiles - Tests for colour fastness - Part E01: Colour fastness to water". The revised text is equivalent to ISO105-E01:1994. According to the provisions of GB/T1.1-1993, the cover and title writing format are modified, the ISO foreword is adopted, the foreword is added, the additional instructions are cancelled, and their contents are incorporated into the foreword. This standard modifies GB5713-85 as follows: 1. Multi-fiber adjacent fabrics and their combination methods with test specimens are added in the corresponding chapters according to the provisions of ISO105. 2. The test water is changed to Grade 3 water.
3. The unit of length is changed to mm.
4. Add three notes: (1) Instrument description in the original appendix; (2) Explain the maximum loading capacity of the instrument; (3) When the specimen is removed from the instrument, air-dried specimens are not allowed.
5. The test report requirements include the addition of the description of the standard number used, the specification of the specimen, and the description of the use of multi-fiber adjacent fabrics according to ISO.
This standard replaces GB5713--85 from the date of implementation. This standard is proposed by the China National Textile and Apparel Council.
This standard is under the jurisdiction of the Standardization Institute of the China National Textile and Apparel Council. The drafting units of this standard are: Standardization Institute of the China National Textile and Apparel Council, Shanghai Textile Standards and Metrology Institute, and Shanghai Wool and Linen Textile Science and Technology Research Institute.
The main drafters of this standard are: Lu Wenbao, Ximin, Zheng Zhijun, Qi Yamin, and Xu Jieshou. This standard was first issued in 1985.

ISOForeword
ISO (International Organization for Standardization) is an international federation of national standards organizations (ISO members). The preparation of international standards is usually completed by ISO technical committees. Each member has the right to participate in the committee if it is interested in a project established by the technical committee. Official and unofficial international organizations, in contact with ISO, can also participate in the work. ISO has close contact with the International Electrotechnical Commission (IEC) in all matters of electrotechnical standardization.
The draft international standard adopted by the technical committee is circulated to the members for voting, and the one with more than 75% approval is published as an international standard. International Standard ISO105-E01 was prepared by ISO/TC38/SC1 Technical Committee on Textiles, Subcommittee on Testing of Colored Textiles and Dyes.
This fourth edition is a technical revision of the third edition, canceling and replacing the third edition (ISO105-E01:1989). ISO 105 has been issued in 13 "parts", each represented by a letter (such as "Part A"), published between 1978 and 1985. Each part consists of a series of "articles", represented by the corresponding letter and two-digit number (such as "Part A01"). These articles are now called "parts", published in separate volumes, but retain the original letters and numbers. There is a complete table of contents in ISO 105-A01. 46

The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised. Parties using this standard should explore the possibility of using the latest versions of the following standards.

The textile sample is placed together with one or two pieces of specified adjacent fabrics, immersed in water, the water is squeezed out, and placed on the two sides of the test device The middle of the flat plate is subjected to the specified pressure. Dry the sample and the adjacent fabric, and use the gray sample card to evaluate the discoloration of the sample and the staining of the adjacent fabric. 4 Equipment and Reagents
4.1 Test device: It consists of a pair of stainless steel frames, with a 5kg weight inside the frame and a bottom of 60mm×115mm. The 40mm×100mm sample placed between glass or acrylic resin plates of about 60mm×115mm×1.5mm is subjected to a pressure of 12.5kPa. The test device should ensure that when the weight is removed during the test, the sample can still be subjected to a pressure of 12.5 kPa remains unchanged. If the size of the combined sample is less than 40mm×100mm, the pressure applied by the weight to the sample should still be 12.5kPa. Note 1 Other devices that can obtain the same results may also be used. 4.2 Oven: The temperature is maintained at 37℃±2℃. 4.3 Grade 3 water (according to GB/T6151-1997,8.1). 4.4 Adjacent fabric (according to GB/T6151--1997.8.2), select one of 4.4.1 or 4.4.2. 4.4.1 One piece of multi-fiber adjacent fabric that complies with GB11404. 4.4.2 Two pieces of single-fiber adjacent fabric that comply with the corresponding chapters of GB7564~~7568. The first piece is made of the same fiber as the sample, and the second piece is made of the fiber specified in Table 1. If the sample is a blended or interwoven product, the first piece is made of the main content fiber, and the second piece is made of the desired content fiber. Or otherwise specified. Approved by the State Bureau of Technical Supervision on June 9, 1997 and implemented on December 1, 1997
The first piece is:
Acetate or triacetate
Polyamide
Polyacrylonitrile

4.5 The grey scale for assessing discoloration shall comply with GB250; the grey scale for assessing staining shall comply with GB251.5 Test specimen
5.1 If the sample is a fabric, prepare the specimen in one of the following ways:a) Take a 40mm×100mm test specimen, place it in contact with a 40mm×100mm multi-fiber adjacent fabric (4.4.1) on the front side, and sew it along one short side to form a combined test specimen.b) Take a 40mm×100mm test specimen, sandwich it between two 40mm×100mm single-fiber adjacent fabrics (4.4.2), and sew it along one short side to form a combined test specimen. 5.2 If the sample is yarn or loose fiber, take yarn or loose fiber equal to about half of the total mass of the adjacent fabric and prepare the sample by one of the following methods: a) sandwiched between a 40mm×100mm multi-fiber adjacent fabric and a 40mm×100mm undyed fabric (4.4.3), sew along the four sides (according to GB/T6151--1997, 9.3.3.4), to form a combined sample. b) sandwiched between two 40mm×100mm single-fiber adjacent fabrics, sew along the four sides, to form a combined sample. 6 Operation procedure
6.1 The combined sample is placed in grade 3 water (4.3) at room temperature and completely soaked. Pour off the solution, place flat between two glass or acrylic resin plates (4.1), and place in a preheated test device under a pressure of 12.5kPa. Note 2: Each test device can hold up to 10 samples, and each sample is separated by a plate. 6.2 Place the device (4.1) with the combined sample in an oven (4.2) at 37°C ± 2°C for 4 h. 6.3 Unfold the combined sample so that the sample and the backing are connected by only one seam (if necessary, disconnect all seams) and hang to dry in air not exceeding 60°C.
Note 3: If air-dried samples are found, they must be discarded and re-tested. 6.4 Use the gray sample card (45) to evaluate the discoloration of the sample and the staining of the backing fabric. 7 The test reportbZxz.net
should include the following information:
a) The number of this standard.That is, GB/T5713-1997: b) the specific specifications of the sample required;
c) the color change grade of the sample evaluated by the gray scale for color change; d) if a single fiber adjacent fabric is used, the staining grade of each single fiber adjacent fabric used; e) if a multi-fiber adjacent fabric is used, the type of multi-fiber adjacent fabric used and the staining grade of each fiber. 48
