Women's clothing fabric Slub denim

The yarn used for slub denim has certain special characteristics compared with the yarn of the usual fabric, so the request for the original yarn is also different. The important reveal is:
1. The warp yarn has lower breaking strength and elongation
The warp yarn process is long, and is often subjected to frequent winding and elongation, and the tension on the machine is relatively high during weaving. As a result, warp yarns require lower yarn breaking strength and elongation.
2. The maturity, levelness and permeability of raw cotton are relatively dependent
Indigo dye depends on its dyeability and fastness to abrasion. It is difficult for cotton yarn spun with maturity-dependent cotton to form uneven dyeing, resulting in blemishes, blemishes and white stars. Therefore, the content of dead petals, dead cotton, and neps should be eliminated as far as possible from the cotton yarn.
3. Longer yarn hairiness
The hairiness of the yarn indirectly affects the quality of the subsequent products. It is difficult to divide the yarns with high hairiness and the warping process, and the end breaks increase. At the same time, it will also cause the dyeing solution to become turbid and thick, and even the pipeline is blocked.
4. Longer yarn defects such as wet strips and slubs
Regarding the usual slub denim , the yarn must be wet, slub and other yarn defects are longer, otherwise it will affect the surface and color of the cloth and increase the rate of end breakage in consumption.
5. Large winding capacity
Generally, the denim yarn count is low, and the single-cone yarn winding capacity should be increased to eliminate the knots on the cloth surface, which is more significant when weaving on a shuttleless loom.
6. The yarn fineness is accurate, the component is dependent, and the component unevenness is small
Denim yarn still needs to ensure that the yarn's fineness, weight, and weight unevenness are within a reasonable range, otherwise it will indirectly affect the control of the weight per square meter.
