Yarn Hairiness and the Process of Winding

Abstract

The influence of winding on yam hairiness is examined, and increased hairiness during winding is verified using a Zweiglc hairiness tester. Spccifically, this study concentrates on the increase of wild hairs on the yam surface after winding, and the relationship between winding tension and yarn hairiness. Fiber transfer is proposed to explain the increased wild hairs; experimental results verify that fiber transfer occurs. A theory is proposed to explain the mechanism of fiber transfer during winding, and experimental results are given to support this mechanism.

Compact Spinning Effect on Cotton Yarn Quality: Interactions with Fiber Characteristics

“…Hair length distribution is well documented in the literature [14,16,17,22,23,26]; It has been shown to have an exponential or an almost-exponential pattern. Barella and Manich [17,26] fitted two (in some cases three) exponential segments to the hair length distribution of various yarn types.…”

“…Hairiness of staple yarns is due to the protrusion of fiber ends and loops from the yarn core [13][14][15]. Its critical importance as a measure of yarn surface integrity has been extensively documented in the literature.…”

Changing Yarn Hairiness During Winding— Analyzing the Trailing Fiber Ends

“…Rust and Peykamian [21] revealed that fibers migrate even during the winding process, increasing yam hairiness afterwards, and a higher winding tension and/or higher yam velocity leads to more fiber migration and hence more severe yarn hairiness. Tarafder [23] studied the influence of the winding process on yam hairiness; he observed that the increased hairiness at the bottom of the bobbin was greater than that at the top after winding.…”
