摘要
为探究数码转杯纺混色纱中纤维混合比例与喂入位置对纤维混合程度的影响,纺制5种纯棉混色纱,制作纱线横截面切片,计算汉密尔顿指数,并结合纱线的纵横向微观结构及织物的外观效应,多方位分析数码转杯纺成纱中纤维混合特征。结果显示:各组分混合比例和其喂入位置对数码转杯纺纯棉混色纱中的纤维转移分布规律无显著影响,各有色纤维的汉密尔顿指数在-25%~25%范围内呈正态分布;表层纤维在纱线纵向不同位置的实际混纺比并不严格一致,纤维的实际含量在设计含量±10%的范围内变化,这种纤维转移特征使纱线及其织物表面呈现出斑斓的梦幻色彩。
In order to study the influence of blending ratio and feed positions on fiber blending in digital rotor spun yarn,five kinds of cotton color blended yarn were produced and the slices of the yarn crosssections were prepared. The vertical and horizontal microstructures of the yarns were observed. The fiber Hamilton indices were calculated. Considering the surface structure of the cloth,fiber blending effects of digital rotor spun yarn were analyzed in different ways. The results show that the blending ratio and the feeding position have no significant effect on the fiber blending; the Hamiltonian index of each colored fiber is from-25% to 25%,showing a normal distribution trend,and the actual proportion of the surface fibers is different in different positions of the yarns,and the actual content of the fiber varies within the range of ± 10% of the design content,so the yarn and cloth surface show gorgeous colors.
