Abstract:

Aiming at the problem on the bigger difference between cashmere length and wool length and hard determination of draft gruge, the cashmere/wool blend yarn and cashmere/wool/ silk blend yarn were spun, respectively, on the JWF-1516 cotton ring frame using the slipping draft or non-slipping draft, and the spun yarn linear density and yarn quality under the slipping draft or non-slipping draft were analyzed. The spinning results show that using the slipping draft or non-slipping draft,  wool/cashmere (84/16) blend yarn and wool/cashmere (65/35) blend yarn with the yarn linear density of 11.1 tex can be spun, and compared with that spun by the non-slipping draft, yarn spun by the slipping draft has significantly reduced yarn thick value and yarn thin value.Using the slipping draft, wool/cashmere (84/16) blend yarn (the single yarn evenness CV value is 19%) with the single yarn linear density of 10 tex and cashmere/wool/silk (80/10/10)blend yarn (the single yarn evenness CV value is 18.8%) with the single yarn linear density of 8.3 tex can be spun, respectively, but the blend yarns of the two linear densities can not be spun by the non-slipping draft.

Key words: cashmere, blend yarn, slipping draft, non-slipping draft
