Abstract (en)
[origin: EP3327186A1] Disclosed is a device for a rotor spinning method using multi-level carding. The device includes a spinning system and a computer control system. The spinning system includes a feeding and carding mechanism, a collecting and twisting mechanism, and a winding mechanism. The feeding and carding mechanism includes a combined feeding roller (2-1, 2-2) with two rotational freedom degrees and a multi-level carding roller (2-6, 2-7, 2-8), the speed ratio of two rollers of the combined feeding roller (2-1, 2-2) with two rotational freedom degrees is adjustable, and therefore the linear density and blending ratio of rotor spun yarn can be regulated and controlled freely. A rotor spinning method using two-cotton-sliver asynchronous inputting and three-level carding is also disclosed.
