Spinning process of anti-pilling light wool

Abstract

The invention discloses a spinning process for anti-pilling type light wool, which comprises the following steps: the first step is to dye the wool at low temperature to obtain dyed wool; ; The moisture regain of the dyed wool after blending is controlled at 28±1%; the relative temperature and humidity of the workshop is controlled at 65%-80%; the third step is to use the woollen carding machine to card the blended dyed wool to obtain Roving sliver; the speed of the roving carding machine is 17.5-18.5m / min; the speed of the rubbing board is 365-375 r / min; the fourth step is to use the roving sliver of the spinning frame for drafting and twisting to obtain spun yarn; draft ratio is 1.38-1.42; the fifth step is to use the automatic winding machine to carry out winding, doubling and twisting of the spun yarn in turn to obtain plush yarn; the tension during doubling is 16-18CN, and the tension during twisting is 30 ‑45CN; the tension is 20‑50CN when winding. The invention has the characteristics of good anti-pilling property and can improve the dyeing effect.

Description

technical field [0001] The invention relates to a wool spinning process, in particular to a spinning process of anti-pilling type light wool. Background technique [0002] Wool is a natural wool fiber, which has excellent curl and elasticity, warm and comfortable, and is deeply loved by consumers. The spinning process of processing wool into yarn is called wool spinning. The existing wool spinning process mainly includes the processing of blending, carding, drafting, spinning, winding, doubling and twisting, etc. The wool processing mainly involves washing the washed wool loose fibers in the blending process according to the blending process. After the oil is proportioned, the warehouse is stuffed to prepare for the subsequent carding work; the carding treatment is to use the roving carding machine to make the wool loose fiber into roving, which can meet the requirements of the spinning frame; Appropriate twist is added to increase the strength of the yarn, and finally the ...

Problems solved by technology

The existing wool spinning process mainly includes processing such as blending, carding, drafting, spinning, winding, doubling and twisting. After the oil is mixed, the warehouse is stuffed to prepare for the subsequent carding work; the carding treatment is to use the roving carding machine to make the wool loose fiber into roving, which meets the requirements of the spinning machine; the spun treatment is to further draw the roving Appropriate twist is added to increase yarn strength, and finally wool yarn is obtained after winding, doubling and twisting processes. However, the prepared wool yarn has poor pilling resistance and will appear after a period of use. ball phenomenon

The color of wool fiber is not bright enough. In order to meet the needs of different consumers, manufacturers often need to carry out corresponding high-temperature dyeing treatment on wool yarn according to the needs of customers before weaving to obtain wool yarn of various colors. Dyeing treatment not only It will lead to the loss of wool fiber, and also lead to the deterioration of the anti-pilling performance of wool yarn; at the same time, due to the tight scale layer on the wool surface, the outermost layer of the wool scale layer also contains a thin hydrophobic layer, which is harmful to the wool. The wettability of the wool surface will affect the adsorption and diffusion of dyes. When wool is dyed by traditional high-temperature dyeing methods, uneven dyeing is prone to occur, and the dyeing fastness is also low, which is prone to fading.

Therefore, the existing technology has the problems of poor pilling resistance and unsatisfactory dyeing effect
