Slub Denim Production: How To Design The Denim Style 3

Production emphasis and quality control

3.1, preparation process;

3.1.1, tension;

3.1.2, reasonable elimination of slub yarn defects. After a long period of exploration and practice, summarize the following points for reference only.

The setting of 3.1.2.1 and yarn number is based on the average number of slub.

The threshold setting of 3.1.2.2 and short slub S is very important, and the roughness is generally set as: the average weight is 1.3 100%, the length is determined according to the original yarn condition and the slub length, generally set at 5CM.

3.1.2.3, close the long and thick L and long detail T threshold, so as not to miss too much.

3.1.3, management in place;

The splicing quality of 3.1.3.1 and Air Twister should be qualified. Attention should not be paid to joints at coarse joints during operation.

3.1.3.2, winding, cleaning of the warping process should be timely and reduce the large section caused by flying attachment.

3.1.3.3, the slub yarns with different length and pitch on the same yarns should be distinguished by name, and should be reinforced with standard colors.

3.2, slurry dyeing process;

3.2.1, the position of the warp shaft, when the warp shaft is configured, the slub yarn should be placed centrally, so as to facilitate the tension adjustment. In addition, the slub warp shaft can be added to the middle of the normal yarn as much as possible, so as to reduce winding and broken ends.

3.2.2, the temperature of the cooking tank and the concentration of the auxiliary can be reduced appropriately.

3.2.3, under the premise of ensuring the success of wet separation, we should use small tension as much as possible at all levels.

3.2.4 and sizing should follow the principle of high consistency and low viscosity, so as to minimize the hairiness regeneration during dry separation.

3.2.5, because of the long hairiness of slub yarn, the cleanliness of guide roller and roller should be well done before starting the machine to prevent sticking and breaking.

3.3. Weaving process;

3.3.1, because of the large difference between bamboo and bamboo varieties, it is difficult to pick up the yarn. It is necessary to carefully comb the yarn, select the needle number reasonably, reduce the head, double head and bite head. Before the shaft is driven, check the cloth carefully, prevent double warp defects and ensure the quality of the upper axle.

3.3.2, the tension of each platform and the process of the machine should be standardized and unified, otherwise it will affect the style of bamboo slub, especially the variety of weft bamboo. It is necessary to strengthen the inspection of the machine surface and adjust the process in time according to the situation, so as to ensure the uniform and stable style of the cloth.

3.3.3 and 2/1's slub

When 3.3.4 and weft slub varieties are produced on air jet looms, the weft stops are higher and should be chosen as far as possible.

The 3.3.5 and latitudinal bamboo varieties are easy to produce the regular defects of the excessive concentration and coincidence of the slub. The following points should be paid attention to:

3.3.5.1 and weft slub yarns must be irregular.

3.3.5.2 and slub use two or more than two weft accumulator, so that the slub can be used alternately to reduce the coincidence rate.

3.3.5.3,

3.3.5.4, we should avoid the slub cycle becoming the integral multiple of widths.

3.3.5.5, the same slub yarn is used to make weft yarn with different varieties. The probability of regular defects is different due to the influence of proportion and width. Therefore, the weft slub varieties should be checked promptly when they are on board, and some problems will be adjusted in time.
