This standard specifies the method for determining the color fastness of various types of textiles to high temperature carbonization with aluminum chloride. Carbonization in a pool is a process designed to remove vegetable impurities. This method is mainly used for wool and wool-containing textiles, especially those that also contain acetate or polyamide fibers.

This standard is based on 1S0105-X:1993 Anti-color Test for Fabrics Part X, Chemical Resistance: Chemical Resistance 3 to GR/T8480-197. This standard is equivalent to B18451S87 standard. The following contents are modified in this standard: 1. According to the modification notice of G3/T1-11U93 and I9-1.12, the cover and title are changed, the format is changed to "implementation", and the foreword and ISO foreword are added. 2. The procedures for writing are written according to S:5. The second chapter is replaced by the second chapter. 3. The length is changed to mm. 4. The content of the test report is added. 5. Appendix A "Control standard sample preparation method" is changed to the main text, and 4.4 is inserted in it. 6. 4. ~ 4. The same as S, this standard replaces GB/T39--18 with the actual flow gate. The standard was proposed by the China Textile Federation. This standard is jointly drafted by the Standardization Research Institute of the China Textile Federation, the Textile Science and Technology Research Institute of the Central Textile Federation, the Beijing Textile Science Research Institute and the Shanghai Textile Industry Technical Supervision Institute. The drafters of this standard are: Che Jinzhu, Fan Lin, Gong Xinyan, Xu Jieshou and Qi Yamin. This standard was first issued in 1987 and revised for the second time in 1998. GB/T8439—1998 ISO Foreword [ISO (International Organization for Standardization) is an international alliance (IS) member of these standards organizations). The preparation of international standards is carried out by ISC technical committees. Members of the technical committees have the right to participate in the review and approval of the projects they have committed to. They are international organizations, both official and non-official, and can also participate in the review and approval of ISO. IS maintains close contact with the International Commission for Standardization (IEC) in the primary projects of electrotechnical standardization. The draft of the international standard adopted by the technical committee can be sent to the members for consultation. 75 is not published as an international standard in the form of a yellow: International Standard 150105-X01 150)/TC:35/SC1 Textile Technical Committee for Colored Textiles and Materials Testing Committee Developed

This standard specifies the method for determining the color resistance of various textile products by carbonization treatment. This carbonization process is designed to remove physical impurities.
This method is mainly applicable to wool and wool-containing textile products, especially those containing polyester fibers: 2 Reference standards
The following references are included in the text, which is applicable in this standard and constitutes the provisions of this standard. When the dent is removed, the version shown is valid. All standards will be subject to the standard.

4 Equipment and materials
4.1 Oven: Dry the sample in air at (±2℃) and bake in air at 115±2℃. 4.2 Aluminum chloride solution (density 1.37g/ml.) contains 514g of aluminum oxide hexahydrate (Al, =5H,0) per liter. 4.3 Hydrogenated liquid: Each liter contains 2ml .20 NH4H2O2 (NH4H2O2>4.4) control cup sample: use C1MurdanlRed3 (sample index, dyed according to the first version and slightly treated with potassium dilute acid). For the control standard, a piece of soaked village fabric is put into a soft bath with 10% sodium sulfate (NS0, 10% steel compound (NS0, 10% CH0 and 3% acetic acid (300g)). The temperature is 4C and the bath ratio is 40:1 in 3 minutes, and the cotton is continued. If necessary, carefully guide the 300g of water to make it into 2% (relative density 1.84) with an exciting bath and then add 15mL. Use cold water to make the dye clean, and add potassium disulfide dissolved in water. Warm the dye bath again, continue to boil for 3 hours, then take out the sample cloth, rinse it with cold self-watering water, and dry it at 4.5. The color change should meet the requirements of the color card B. State Quality and Technical Supervision 199B1126 approved 70

5 Test specimens
CB/T8439-1998
5.1 For high-quality fabrics, take a 40ranx_mn test specimen: 5.2 For sample fabrics, take a 40m100mm test piece, or make a test piece with end parallelism of 100mm and a diameter of about 5m, and take two test pieces from north to south.
5.3 If the sample is of sufficient fiber content, press it into a 40mmx1U0mm square. 6. Operation procedure
6.1 Place the reduced sample or control standard sample in the test and perform the test as described in 6.2-5.5. 6.2 Place the sample in a sodium hydroxide solution (4.2:5:1) until it is clear and the concentration is 2U:1. Press the sample to make the concentration be 0% of the body mass. www.bzxz.net
6.3 Place the sample in an oven at 61r=2t and bake for 3 min, or longer if necessary. Then raise the temperature and bake at 115°C for 25 min. 6.4 Place the sample in a flowing stream and divide it into two halves. Place one half in a narrow atmosphere. 6.5 Place the other half in ammonium hydroxide (4.3) at room temperature for 30 min (bath ratio 40:1) and then rinse with running cold water for 5 min. Let the lower half dry in air without rapid flow. 6.6 Assess the color change of the mold (4.4) after neutralization according to the gray scale. Precision, the color change of the standard sample is not accurate enough, please follow 6.【~.6-6, and repeat the test with a new test piece and a new standard sample. 6.7 The gray sample card will be half the color of the sample. 7 Test report The test report shall also include the following: a) The serial number of this standard, i.e. GB9439-1918 b) Sample size: tt) The color change frequency of the two washed and neutralized samples
