Title:
ROTOR SPINNING METHOD AND APPARATUS USING THREE-COTTON-SLIVER ASYNCHRONOUS INPUT AND MULTI-STAGE CARDING
Document Type and Number:
WIPO Patent Application WO/2017/031612
Kind Code:
A1
Abstract:
An apparatus for a rotor spinning method using multi-stage carding comprises a spinning system and a computer control system. The spinning system comprises a feeding and carding mechanism, a collecting and twisting mechanism, and a winding formation mechanism. The apparatus is characterized in that the feeding and carding mechanism comprises a combined cotton feeding roller (2-4, 2-5, 2-6) with three degrees of rotational freedom and a multi-stage carding roller (2-8, 2-9, 2-10), the speed ratio of three rollers in the combined cotton feeding roller (2-4, 2-5, 2-6) with three degrees of rotational freedom is adjustable, and therefore the linear density and blending ratio of rotor spun yarn can be regulated and controlled freely. Also disclosed is a rotor spinning method using three-cotton-sliver asynchronous input and multi-stage carding.
