Slub Denim Production: How To Design The Denim Style 2

Fabric design points:

2.1.

When 2.1.1 and cloth samples are available, the length of slub can be measured directly from cloth.

Because the slub length of irregular yarn usually has a range, we should take a few more to understand its main length. In addition, we should also consider the influence of shrinkage and pre shrinkage and adjust it.

If 2.1.2, no sample, if slub fabric is designed, the slub length should be less than 5cm. The slub length of long slub fabric should be about 8 - 20cm.

2.2.

2.2.1, when the sample size is large, the yarn removal method is adopted to intercept the coarse section and the detailed number of segments. The slub roughness can be known. At the same time, the analysis of the base yarn should also be accurate, otherwise it will affect the effect after matching.

2.2.2, when the sample is too small to be disassembled or designed by itself, we can refer to the following points.

The 2.2.2.1 and the unwashed bamboo knots obviously raised, and the slub roughness should be 2 times higher than that of the base yarns.

2.2.2.2, without bamboo washing, energy saving can be seen but not obvious, and the length of slub should be designed 1.6 to 1.9 times that of base yarn.

2.2.2.3 can only be seen after washing, and the slub roughness should be 1.4 to 1.5 times the base yarn.

When the roughcast of 2.2.3 and zonal slub should be designed more than 2 times of the zonal base yarn, the slub effect can be seen, so the roughness should be larger than the meridian direction.

2.2.4 and slub roughness are the key points to decide the style of slub fabric. Before design, we must know whether the style of pursuit is rough or hazy. The daily production of slub varieties needs to be accumulated and washed.

2.3.

The length of 2.3.1 and slub yarn should be 25-40%, and the bamboo knot is not easy to be too dense. Otherwise, the slub and pitch spacing are too different, and the production quality can not be guaranteed. In addition, if the original yarn is too dense, the slub will not disperse.

2.3.2,
