Introduction:
This yarn hairiness testing equipment is the special-purpose equipment determines the yarn hairiness index. And this equipment applies to testing various natural fiber and chemical fiber with pure or mixing form hairiness length, hairiness index and distributing for the textile mill and scientific research, teaching, foreign trade, commodity inspection, etc. to instruct producing, improve the craft, control quality, to research new products, and offer the means of appraising to yarn users.

Yarn hairiness is fibrous end or fibrous loop that reaches out yarn’s surface.

There is close relationship between hairiness length, quantity, distribution and fabric inherent quality, appearance quality, feeling. Hairiness length, quantity distribution are also major influence factors of quality and productivity especially in the shuttle less-loom, knitting production, therefore the hairiness index is a important index of appraise yarn quality, is also the important component basis of reflecting good and bad spinning and weaving.
