Balling-up-resisting light wool spinning technology

Abstract

The invention discloses a balling-up-resisting light wool spinning technology. The technology comprises the following steps that firstly, wool is subjected to low-temperature dyeing, and dyed wool isobtained; secondly, a blending willow is used for carrying out blending on the dyed wool, the online moisture regain of the blended dyed wool is controlled to 28+ / -1%, and the workshop relative temperature and humidity can be controlled to 65 to 80%; thirdly, a roving carding machine is used for carrying out carding treatment on the blended dyed wool, a rough sliver is obtained, the speed of the roving carding machine is 17.5 to 18.5 m / min, and the speed of a rubbing plate is 365 to 375 r / min; fourthly, a spinning machine is used for carrying out drafting and twisting on the rough sliver, a fine sliver is obtained, and the drafting ratio is 1.38 to 1.42; and fifthly, an automatic winding machine is used for sequentially carrying out winding, doubling and twisting on the fine sliver, wool yarn is obtained, during doubling, tension is 16 to 18 CN, during twisting, the tension is 30 to 45 CN, and during spooling into a spool, the tension is 20 to 50 CN. The technology has the advantages of being good in balling-up resistance and capable of improving the dyeing effect.

Description

technical field [0001] The invention relates to a wool spinning process, in particular to a pilling-resistant light wool spinning process. Background technique [0002] Wool is a kind of natural wool fiber. It has excellent curl and elasticity, keeps 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 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 ...

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
