manufacturing method of stretchable blended spun yarn by performing double carding process

摘要

A method for producing a stretchable mixed yarn by double carding according to the present invention is a first carding machine for a first spinning type, carding first stretchable fibers and second non-stretchable fibers, A first carding step of producing a first sliver in which the first and second fibers are blended; Stretching the third sliver with the non-stretchable third fiber to pass through the opening and hitch surface for the second spinning method to produce a second sliver in which the first, second, and third fibers are blended, And horn surface process; And a second carding process for the second spinning system having a carding resolution higher than that of the first carding device and a second carding process for manufacturing the third sliver by carding the second sliver .
