Abstract:

In order to clarify the classification of characteristics of digital yarns based on the digital ring spinning and its influence on the fabric structure and appearance. By analyzing the principle of two-channel two-stage drawing digital spinning, a variety of yarns with varying linear densities or blending ratios were spun. The characteristic parameters of digital yarns were selected to include the base linear density, cycle length, variation range of blending ratio (linear density), number of fragments within a cycle or variation gradient between two adjacent segments. It is concluded that the greater the variation range of blending ratio (linear density), the stronger the segment color (slub) effect, and that the width of the fabric strip is determined by the cycle length and a longer period corresponds to a wider segment effect. The number of segments contained in a cycle has certain influence on the strength of segment color effect, and as the number of segments increases the segment color effect demonstrates a decrease.

Key words: ring digital yarn, yarn, blending ratio, linear density, segment color effect, slub effect
