Technical Field

The invention relates to a spinning method of a rotor spinning color spinning fabric with a hollow-out effect.

Background

The rotor spinning apparatus produces yarns that differ substantially in structure from ring spun yarns, which in turn results in differences in yarn properties, appearance, etc. The rotor yarn is composed of a yarn core and an outer wrapping fiber, the structure of the yarn core at the inner layer is compact, and the structure of the outer wrapping fiber is loose. However, in the rotor spinning stage, the raw material is subjected to strong opening and cleaning and impurity removal processing, and the feeding fiber is fully carded by the carding roller in the spinning process, so that neps in the yarn are relatively less in impurity, and are generally 20-30% less than ring spun yarn.

The traditional ring spinning colored spun yarn is widely applied to the fields of T XUE, home clothes, home textiles and the like because the fabric of the traditional ring spinning colored spun yarn has a unique gray-grey three-dimensional effect. The rotor spinning equipment is difficult to modify, and only common yarns can be produced, so that the yarns have single structures and low market acceptance. Therefore, the rotor spinning color spinning fabric with the hollow-out effect is developed by adopting the environment-friendly viscose which is prepared by taking the wood of the sustainable development forestry plantation authenticated by FSC as the raw material of the spinning fiber, mixing the dyed environment-friendly viscose with the white viscose to prepare the cotton sliver and refitting the cotton feeding roller component in the rotor spinning device, is popular in the market, overcomes the defect that a rotor spinning machine can only produce yarns with common structures, produces products required by the market, and brings benefits for enterprises.

the environment-friendly viscose is dyed into extra black, blue and peacock blue, and then one, two or three of the materials are mixed with the white environment-friendly viscose according to a certain proportion and respectively subjected to the working procedures of cotton blending, cotton carding and drawing for later use.

Furthermore, the opening and picking process adopts a mode of 'transversely spreading and directly taking' to carry out manual mixing, the uniformly mixed raw materials are directly put into a cotton grabbing machine, and a technological principle of 'fine grabbing, low speed, more loosening and less beating and combing for beating' is adopted. The main process parameters are as follows: the beater speed is 830r/mim, the roller speed of the cotton roll is 15r/mim, and the dry weight of the cotton roll is 400 g/m.

Furthermore, in the cotton carding process, the 100% environment-friendly viscose fiber has less impurities, mainly carding, and mainly adopts the following technical measures: the cylinder to cover gauge is suitably enlarged, i.e. 0.25mm, 0.23mm, 0.22mm, 0.25 mm.

Furthermore, the drawing process adopts three combining processes, properly adjusts the head and back zone draft multiple and spacing distance to be beneficial to eliminating the front hook, and the main process parameters are as follows: the total draft was 6.5 times, the roller gauge was 13.5mm 19mm, and the cooked sliver basis weight was 21.5g/5 m.

Furthermore, the spinning process reduces the production speed and yarn breakage, and the main process parameters are as follows: the rotor spinning speed is 280m/min, the feeding ratio is 0.99, the total drafting multiple is 218 times, the rotor rotating speed is 8000r/min, the yarn leading speed is 230m/min, and the twist coefficient is 380.
