密度差에 따른 毛編織物의 收縮率에 관한 硏究

Abstract

This study was carried out on the washing of fabrics knitted from wool and wool/ man-mado fibre blends. Two of them were all wool and the rest were wool/ man-made fibre blends. Each of them had two kinds of knit structure, plain and rib stitch, and all the structures had three level of compactness. The washing was operated by the wash wheel method. In order to find out the dimensional changes of the fabrics during washing, it was measured the area shrinkage of all the specimen which was marked with indiable color thread. Besides, the tests of wear, thickness, strength and air permeability was carried to find out the relation of structure compactness and other properties. There were three significant interaction between the factors for the data. These showed that 1) the shrinkage rates of the fabrics was decreased by increasing cover factor 2) the shrinkage rates between plain and rib stitch were very close together when cover factor was constant, and 3) Thickness and strength of the fabrics were increased by increasing cover factor, on the other hand wear and ?ir permeability of the fabrics were decreased by increasing cover factor.
