Abstract:

In order to compare the performances of line flax/polyester multifilament composite yarns by different composite processing methods, the spinning process parameters were designed by modifying existing spinning equipment, and 5 composite yarns with the same twist were spun. The appearance characteristics, tensile properties and hairiness of composite yarns were compared and analyzed. The results show that the composite yarns by different spinning methods are all of obvious characteristics of uneven distribution of twist; the wrapped composite yarns have better covering effect than the composite yarns of twisted structure; compared with the breaking strength, composite processing has better improve effect on the minimum strength of the line flax yarn, and can significantly reduce the strength unevenness; all the composite yarns can be woven without sizing except the wrapped yarn of same twist direction; and the double-twist and Sirofil composite processed are effective in improving the breaking elongation rate of the yarn, and the effect of wrapping composite to reduce the hairiness of the line flax yarn is the best.

Key words: line flax, polyester multifilament, composite yarn, Sirofil, wrapped spinning, double-twisted spinning
