The results of decreasing dyeing temperature, shortening the dyeing period, reducing the fiber damage and improved quality of the cashmere have been obtained. The percentage of dyeing exhaustion and color fastness of final products were further improved in this regards. A suggested technique, bath ratio, dyeing process curve and dye recipe were raised in the paper. SFR-503’s swelling, wetting, leveling, brightening effect for cashmere during dyeing process were discussed.展开更多

Male and female Raeini cashmere goats （〈1.5 years of age, n=48） were selected from flocks raised at a government breeding station or raised commercially under either rural or nomadic conditions. The staple length, cashmere fiber diameter, coefficient of variation for fiber diameter, percentage of cashmere in a fleece, percentage of guard hair in a fleece and cashmere tenacity averaged 4.6 ±0.1 cm, 18.0 ±0.1 um, 20.9±0.4%, 66.1 ± 1.5%, 33.8± 1.5% and 1.8±0.2 gf/tex, respectively. The sulfur, copper and zinc content of the cashmere averaged 2.8 ± 0.1%, 0.00065 ± 0.00002% and 0.01276 ± 0.00025%, respectively. Rearing method significantly affected staple length, coefficient of variation of fiber diameter, cashmere tenacity and copper content. Males had a higher coefficient of variation of fiber diameter and cashmere tenacity than females （P 〈 0.05）.展开更多
