Organic solvent friction dyeing fastness test method and selection equipment Organic solvents are organic compounds that can dissolve some water-insoluble substances (such as oils, waxes, resins, rubbers, dyes, etc.) and are characterized by being liquid at normal temperature and pressure and having a large volatility. In the dissolution process, the properties of the solute and the solvent did not change. This article focuses on a test method for the fastness to rubbing of organic solvents (usually used for cleaning stains on textiles, etc.). To master a test, the first thing we must know is its principle. The principle of the test is to immerse the sample and the artificially dyed cotton cloth in organic solvents, rub it in a certain way with a friction tester, and then The discoloration of the sample and the stained condition of the unstained cotton cloth were evaluated with a color change gray card and a stained gray card, respectively. This test may be used to achieve a high detection equipment Dongguan Xin GX-5072 friction test machine dyeing fastness, color fastness rubbing tester main specifications are as follows: According to standards: JIS0849-2004, ISO105-X12-2001 and other test standards Test piece: 22×3cm White cotton cloth: 5×5cm Friction speed: 30cpm Friction hammer load: 200,500g Friction distance: 100mm Counter: LED display 0 to 999,999 (six digits) Motor: 1/4HP Volume: 57×55×33cm Weight: 60kg Power Source: 1∮, AC220V, 3A Friction dye fastness tester test steps are as follows 1. Place the specimen and the unstained frictional cotton cloth in advance in a standard condition for not less than 4 hours. 2. The unstained frictional cotton cloth is moistened with an organic solvent content of approximately 100% . After rubbing the sample with it, the sample is dried in a desiccator at a temperature not higher than 60 °C. 3. Put the sample on the test bench, and the unstained friction cotton cloth moistened with organic solvent is placed on the surface of the friction finger and rubbed 100 times along the 100mm track at a rate of 30 times / min . on the sample. The surface applied load is 20N. 4. Evaluation of test results: The discoloration of the sample and the stain level of the unstained rubbing cloth were evaluated. The machine is independently developed by Gaoxin, with a one-year warranty and lifetime maintenance. During the warranty period, services such as free maintenance, periodic inspections, troubleshooting, operation training, etc., will be periodically performed on the equipment used by the customer. Everything is done to solve the worries of customers' customers and help them effectively improve their performance and competitiveness.
