AATCC 162 16 CFR Part 1610.6

G) method of dry cleaning for fabrics (refer to AATCC 162_2008)(see appendix I)

H) instrument testing standards/methods (see appendix ii)

Appendix I: dry cleaning method for fabrics (refer to AATCC 162_2002)

1, the dry cleaning method here refers to a certain environment (such as a certain temperature, time, pH value and hardness) will be yarn or fabric

Dip into a dilute solution of chlorine and shake at a certain rate.

2. After dry cleaning, wring out the fabric and then blot it with filter paper, and then conduct color fastness evaluation.

3. Preparation of reagents:

Add 5ppm chlorine and 100ppm salt to 5000mL distilled or deionized water, and add sodium carbonate and acetic acid to form a pH of 7.0

A solution of reagents. Solution temperature 21℃.

4. Test samples:

The sample size is about 6x6cm. Total weight 5.0g±0.25g, including control cloth. If the total weight of a single sample is less than 5g, it can be used

Multilayer. Samples of different colors can be mixed together to form a total load of 5.0g.

5. Test steps:

5.1 clean cylinder: add about 5000mL of deionized water and 0.5mL of sodium hypochlorite (5.25%) into the cylinder, cover the cylinder head and run about

10 minutes, then pour out the solution. Cleaning of the cylinder block is only necessary after other tests or if it has not been used for more than two weeks.

5.2 configuration of hardness concentrated reagent

- 8.24g anhydrous calcium chloride (CaCl2) and 5.07g magnesium chloride hexahydrate;

- add 800mL of deionized or distilled water to 1L graduated measuring cup, add the above-mentioned calcium chloride and magnesium chloride, stir while adding, and then make up 1L of water. This is a "hard concentrated reagent" that can be retained for up to 30 days.

5.4 dilute 51mL "hardness concentration reagent" to 5100mL with deionized or distilled water, and then add 0.5ml sodium hypochlorite. Determine the actual PPM value of Cl and adjust it to 5ppm by titration.

5.5 a reagent solution with a pH of 7.0 is prepared by adding sodium carbonate (Na2CO3) and acetic acid (CH3COOH).

5.6 add 5000mL of the solution configured in 5.4 above to the cylinder and adjust the solution temperature to 21℃.

5.7 put the test sample and control cloth into the cylinder and run for 60 minutes.

5.8 take out the sample and control cloth and extrude the solution with the rolling mill. Rinse thoroughly with deionized or distilled water. Then wring it out and letting it dry at room temperature on bleached or absorbent paper towels.

5.9 so far, the whole dry cleaning process is over.

Note: if the sample is prepared for combustion testing, water may be required prior to testing, as in 16 CFR Part 1610.

Please refer to the corresponding test standards for details.
