Abstract

The aim of this work is to determine
the effect of draft ratio and twist level on core visibility ratios of dual
core-spun yarns. For this aim, different
types dual-core yarns containing PET/Elastane were produced under controlled
conditions. To objectively evaluate the
visual quality of the dual-core yarns, the frequency of the core filaments
appearing on the yarn surfaces was counted on dyed
knitted fabrics produced with these yarns by using image processing algorithm. The results showed that the draft
ratio and twist coefficient are the important factors influencing the core
visibility ratios of dual core-spun yarns.

Keywords

Dual-core yarn, pre-treated dual-core yarn, core visibility ratio, draft ratio, twist coefficient
