Most of wool spinning enterprises sell the short combed wool to wool spinning enterprises or felting factories and the like at a lower price so as to prepare low-grade short combed wool textiles. In order to improve the quality and the grade of a wool spinning product, the combed short wool is subjected to rotor spinning, so that the quality and the wearability of a textile are improved, and meanwhile, the production and manufacturing cost can be reduced.
In the patent of processing method for spinning polyester rotor yarn (application number: 200710044656.3, publication number: 101294323, published as 2008.08.07), polyester fiber is fed into a carding machine for carding, impurity removal and uniform mixing, and is transferred onto doffers to be stripped by a stripping roller and enter a bell mouth to be made into quantitative sliver; making the raw slivers into quantitative cooked slivers by a first drawing frame and a second drawing frame; opening, removing impurities, twisting and winding the drawn sliver by a rotor spinning machine to obtain the Terylene rotor yarn; the process is complicated and tedious, has a plurality of devices, and is not beneficial to actual production. Combed staple fibers have the softness of textile fibers, typically having a fiber length of no greater than 30mm (with the exception of very small amounts of fiber), but combed staple fibers have good elasticity, natural crimp, and large static electricity, which properties make rotor spinning of the fibers difficult. Therefore, in the field of textiles, the method for preparing the combed short-hair rotor yarn has important significance.

Detailed Description
The present invention will be described in detail with reference to the following embodiments.
The invention relates to a preparation method of combed short-hair rotor yarns, which specifically comprises the following steps:
step 1, blending: adding water and antistatic agent into the short combed wool on a wool blending machine, wherein the moisture regain is 23-28%;
step 2, sliver combing: putting the combed short wool in the step 1 into a cover plate carding machine, carding the combed short wool into strips, wherein the mass of the raw strips is 12g-16g/5 m;
step 3, drawing: putting the medium-combed short wool tops obtained in the step (2) into a drawing frame, and drawing twice, wherein the first drawing and drawing ration is 10g-14g/5m, and the second drawing and drawing ration is 10g-14g/5 m;
step 4, stretch breaking: putting the combed short wool slivers subjected to twice drawing in the step 3 into a roller stretch breaker for stretch breaking, and simultaneously stretch-breaking longer combed short wool fibers in the slivers, wherein the length of single fibers in the combed short wool slivers is not more than 35 mm;
step 5, drawing: putting the short combed wool slivers obtained in the step 4 into a drawing frame for drawing, wherein the quantity of drawn slivers is 10-15 g/5 m;
step 6, spinning: putting the combed short wool slivers subjected to drawing in the step 5 into a rotor spinning machine for spinning to prepare combed short wool rotor yarns, wherein the linear density of the combed short wool rotor yarns is 51tex-61 tex; wherein the technological parameters of the rotor spinning machine are as follows: the rotating speed of the rotor is 50000r/min-60000r/min, the yarn leading speed is 60m/min-85m/min, and the carding roller speed is 6000r/min-7000 r/min.
The invention relates to a preparation method of combed short-hair rotor yarns, which has three main innovation points:
firstly, adding a proper amount of water and an antistatic agent into the short combed wool before carding the cover plate, and because the short combed wool contains wool-blending oil, the wool-blending oil is not required to be added, so that the generation of static electricity in the combing of wool fibers can be reduced, and meanwhile, the pollution of the wool-blending oil to a combing roller and a rotor in a rotor spinning machine is also reduced;
secondly, because combed short wool contains a small amount of long wool fibers, and the long fibers can influence the quality of a final product in the rotor spinning process, a roller stretch-breaking process is added before a drawing process, so that the long wool fibers can be broken;
thirdly, because the combing short wool fiber has good elasticity and crimpability, the speed of the combing roller and the rotor is reduced in the rotor spinning process, and the damage to the scales on the surface of the combing short wool can be reduced, so that the scale dust is reduced to be deposited in a rotor condensation groove, and the smooth proceeding of the rotor spinning process can be ensured.
