초록
Effects of pH and temperature on shrinkage of grey knits (slip) and effects of scouring renditions on shrinkage, reflectance, handle and reactive dyeing Properties of loon cotton warp knits were studied. The results are as follows. In solution of room temperature and pH 71-13 the maximum area shrinkage was about 20%, pH has no effect on area shrinkage but on linear shrinkage. Three dimensional the loop which caused a knit to shrink was caused by the twist of yarn. Temperature has no effect on area shrinkage of grey knits. In mixed solution of sodium hydroxide and soda ash, the decrease of concentration ratio of soda ash made the reflectance decrease and the softness increase. Equilibrium adsorption was decreased as the pH of dye bath increased but the maximum fixation was obtained at pH 10. Scouring conditions have some effect on the rate of adsorption but a few effect on the rate of fixation.
