국산편직물의 신축성 한계에 대한 연구

Studies were carried out on shrinkage of cotton rib knit fabrics and the following results were obtained: Wale shrinkages increase abruptly in (+) direction and course shrinkages in (-) direction beyond a certain c.p.i. limit. Effects of the immersion time and temperature to shrinkages are random and negligible. Bleaching increases considerably the shrinkages of rib knit fabrics. Area shrinkages increase linearly with c.p.i and the more complex the constructions are, the larger the increasing ratios. Increasing ratios of area shrinkage of bleached are larder than the scoured and immersed.
