Embodiment

[0018] A kind of spinning technology of cotton-polyester siro spinning AB yarn, at first pure polyester is made into A roving, pure cotton is made into B roving, concrete process steps are as follows:

[0019] For A roving: first, carry out the cleaning process on A roving, the process parameters are 920 r / min for the combined beater speed, 1250 rpm for the fan, and 8×18 mm between the beater and the dust bar; then carry out the carding process for the A roving, The process parameters are cylinder speed 340 rpm, cover plate speed 80mm / min, cover plate gauges are 0.23mm, 0.2mm, 0.2mm, 0.2mm, 0.23mm; and finally A roving pre-drawing is obtained.

[0020] For B roving: first, carry out the cleaning process on B roving, the process parameters are 920 r / min for comprehensive beater speed, 1250 rpm for fan, and 8×18 mm between beater and dust bar; then carry out carding process for B roving, The process parameters are cylinder speed 340 rpm, cover plate speed 196mm / min, cover plate ...

Abstract

The invention relates to the field of spinning and weaving and particularly relates to a yarn spinning process of cotton polyester siro-spun AB yarns. The yarn spinning process comprises the following steps of: (1) prefabricating a blended drawing stripe; (2) a drawing procedure: taking 6 threads of A yarn prefabricated drawing stripes and one thread of B yarn prefabricated drawing stripe and preparing into the blended drawing stripe containing 88% of polyester and 12% of cotton; taking 4 threads of the blended drawing stripes and 4 threads of the B yarn prefabricated drawing stripes, and mixing according to a mutual separation manner to prepare AB yarn stripes, wherein in a drawing process, the back zone drafting multiple is set to be 1.75, the roller gauge length is 12mm*15mm and the vehicle speed is controlled to be 200m / min-220m / min; (3) a roving procedure; and (4) a spinning procedure. Compared with the prior art, the prepared siro-spun AB yarns have a relatively strong cloth hazy feeling and the cloth does not easily have color difference cross lines; prepared cotton polyester siro-spun AB gauze has good visual effect and aesthetic feeling.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a spinning process of cotton-polyester siro spinning AB yarn. Background technique [0002] The common cotton polyester siro spinning AB yarn in the market is made by feeding a cotton roving sliver and a polyester roving sliver in parallel from the spun yarn drafting area at the same time, and spinning through drafting and twisting. The single-dyeing process of the high-quality fabric can make the cloth surface present a special visual effect, which is popular among consumers. However, this spinning method is relatively common, and the effect of the spun gauze surface is average, and the siro-spun AB gauze surface is prone to chromatic aberration and cross paths, which seriously affects the aesthetic feeling and visual effect of the gauze. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention designs a cotton-polyester siro spi...
