A Study on the Change of Physical Properties of Lining Fabric by Washing

세탁에 의한 안감의 물성변화에 관한 연구

This study was to investigated physical properties of lining fabric (Nylon, Acetate, Rayon and Polyester) such as shrinkage, tensile strength, moisture regain and crease resistance. The results were as follows. 1. The number of repeated washing times and the concentration of the detergent almost didn't affect on the change of tensile strength. 2. As washing increase more, the shrinkage of all sample was more increased. In the case of Rayon, it was showed that shrinkage was high by $1{\sim}3$ times washing. In the case of Nylon, it was showed minus shrinkage according to frequency of washing. 3. The moisture regain was very decreased by 1 times washing. But the moisture regain was increased with increase in frequency of washing and resulted in it was showed a similar value with controls. 4. As the frequency of washing and the concentration of detergent increase more, the crease resistance was decreased considerably because the elasticity of fiber decreased by mechanical force such as tension, bending and pressure and alkali.
