PURPOSE:The over-feed rate in the bind-spinning process and the twist number in the twisting process are kept in a specific relationship to produce the titled spun yarn with improved yarn-collecting properties, touch and apearance. CONSTITUTION:A staple fiber bundle which is drafted in the drafting zone 10 is sent out of the front rollers 11 to the false-twisting nozzle 15 by means of the yarn-conveying means 13. Then, twisting and untwisting are effected under over feed conditions to form a bind-spun yarn. Then, the resultant spun yarn is subjected to real twisting in the same direction as the twisting direction in the false twisting nozzle in a range in twisting number represented by the equation (the unit of overfeed is %; K is metric count) to give the objective real-twisted bind- spun yarn. The overfeed rate is preferably 3-40%. |
