3 Principle
The sample was washed in a drum type washing machine under specified conditions. After washing, remove excess water and place the sample on the sieve in the oven.
Flat, remove the wrinkles by hand, taking care not to stretch or deform it, the oven temperature is 60 ° C ± 5 ° C, and then let it dry. Separately measured before washing
The distance between the warp and weft marks of the back sample.
The pre-conditioned humidity and test atmosphere are carried out in accordance with the provisions of GB 6529.
4 reagents
Water. Soft water should be used. The hardness of water is expressed in GB/T 7477 and expressed as calcium carbonate. The hardness of the water used in the arbitration test is not exceeded.
