Secondly, especially with cotton yarn compared to strong and weak elasticity, the ruler pure cotton overalls (factory clothes) out of the fold after the time will be slightly longer, the most simple distinction: the work clothes (factory clothes) wanton back grab a grasp in the hands, and then let go, if the wrinkle is very sharp, that means cotton, or cotton identity many. If the imprint of the wrinkle is very small, the description is mixed with other identities.
