How To Prevent And Solve Weft And Skew In Fabric Processing?

How to prevent and solve weft and skew of fabric?

The prevention of weft and skew is mainly controlled in the process of finishing. The weft and skew weft can be solved either by sorting and reworking, or by arranging the boards of garment factories.

　 (1) methods of solving weft and weft arc in dyeing factories. Any gray fabric will have the phenomenon of weft and weft. When the gray cloth is in normal condition, the internal stress will be basically eliminated after singeing, desizing, mercerizing, drawing and shrinking, that is, the weft deviation rate of fabric after washing is very small.

　　 The new type of drawing device adopts two straight pulling rollers to adjust the drawing amount of the fabric at the same time changing its longitudinal and transverse positions. The pulling effect of the device has been obviously improved, and the problem of drawing and wrinkling has been effectively solved. The traditional drawing device is adjusting the amount of fabric's slant by changing its position in a longitudinal direction through a plurality of rollers.

In the production process, first of all, ensure the consistency of the skewness of the whole batch of goods. This is the key to control the skew. The weft deviation of the whole batch fabric should not be too large. In the production process, the technological parameters of the skew size should be adjusted first when the slant consistency is satisfied.

　　 (2) the way to solve the weft arc is: It is not very important whether the cloth head should be aligned when the cloth is turned, but it is necessary not to cause too much pull on the fabric.

The cloth head should be ripped straight and straight. This is the necessary guarantee for reducing the crevice of the seam and preventing the new irregular weft of the cloth head. As far as possible, the cloth can be evenly stressed to prevent and reduce the appearance of new weft. The weft arc can be weft through the bending roller weft straightening device, and the weft can be weft through the drawing device, and the weft can be weft by desizing or rolling the piled heap.

　　 (3) ways to solve weft insertion in garment factories: The fabric can be released and rolled up for about 24h. The internal stress of the fabric can be better released, which can improve the weft slope of the fabric, especially the elastic fabric.

　　 The precondition of adopting the above method is that the weft angle of the fabric is the same, the weft deviation between the coil and the coil is not very different, and the weft of the fabric is smaller. The automatic discharge system of the CAD system now has a skew correction function. Input "offset" and "skew" can get a distorted template at a time.
