1. Working principle and introduction


A) This instrument is used to test the color fastness of dry cleaning and washing with chlorine water, and to prepare samples for flammability test;


B) The instrument has a simple structure and is mainly composed of a main engine and a washing cylinder.


C) The main engine is composed of the fuselage, motor, motor drive part, time controller, etc.;


D) Time and speed can be adjusted;


E) Jog (Jog) function can be used to adjust the cylinder head upward.


F) STM292 dry cleaning and washing cylinders are applicable to the following standards (or methods) :


AATCC 162 16 CFR Part 1610.6


G) About dry cleaning methods for fabrics (refer to AATCC 162_2008)(see Appendix I)


H) Instrument testing Standards/Methods (see Appendix II)


Appendix 1 On dry cleaning methods for fabrics (refer to AATCC 162_2002)


1. The dry cleaning method mentioned here refers to the use of yarn or fabric under certain conditions (such as a certain temperature, time, pH value and hardness)


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


2. After the dry cleaning, the fabric is wrung out, then the filter paper is sucked dry, and then the color fastness is evaluated.


3. Preparation of reagents:


5ppm chlorine and 100ppm salt were added to 5000mL distilled or deionized water, followed by sodium carbonate and acetic acid to form a pH of 7.0


Of the reagent solution.

The solution temperature is 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 for a total load of 5.0g.


5. Test Steps:


5.1 Clean cylinder: Add about 5000mL deionized water and 0.5ml sodium hypochlorite (5.25%) into the cylinder, cover the cylinder head, and run about


10 minutes, then pour away the solution.

Cylinder cleaning is only necessary if other tests have been done or if the cylinder has not been used for more than two weeks.


5.2 Prepare concentrated reagent for hardness


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


- Add 800mL deionized or distilled water to 1L graduated measuring cup, add the above calcium chloride and magnesium chloride, stir while stirring, then make up 1L with water.

This is called a "hardened concentrated reagent" and can be kept for 30 days.


5.4 Dilute 51mL "hardness concentration reagent" to 5100mL with deionized water or distilled water, and then add 0.5ml sodium hypochlorite.

Determine the actual Cl PPM value and adjust to 5ppm by titration.


5.5 A reagent solution with a pH of 7.0 was 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 a mill.

Rinse thoroughly with deionized or distilled water.

They are then wrung out and dried at room temperature on bleached and absorbent paper towels.


5.9 At this point, the whole dry cleaning process is over.


Note: If the sample is prepared for a combustion test, washing may be required prior to the test, as in 16 CFR Part 1610.


Please refer to the corresponding test criteria for details.


Instrument test standard:


Test standard test range test sample test solution test time


AATCC 162-2002 Used to evaluate the colour fastness of various yarns and fabrics dyed, printed or otherwise dyed, 6x6cm after soaking in swimming pool water, with a total weight of 5g ± 0.5g, including control cloth.
