Problems And Countermeasures In Weaving
Jun 09, 2018

The high speed shuttle less webbing machine is a new type of woven shuttle less weaving machine suitable for producing a variety of narrow webs, especially elastic light or medium webbings. The following mainly analyzes the problems that are common in the weaving, storage, transportation, and dyeing of elastic webbings in shuttle less webbing machines, and analyzes the causes of these problems and the process adjustment methods.

Inconsistency in width

The fabric width is based on the requirements of the customer's technical data and is controlled within the allowable upper and lower deviation range. However, in the process of weaving, the width is often inconsistent.

For example: 1) enter the wrong reed at the chain edge or steel wire edge. The function of steel wire edge is to balance the density of the fabric on both sides of the body in the process of weaving. The width of the base steel wire is changed more or less by more or less one grid. 2) there is an obstacle to the weft thread. If the position of the weft is wrong, there is a problem with the weft winding at a certain position or the weft winding itself. 3) the thickness of filling materials is not consistent. Rayon and cotton yarns are easy to be too thick or too thin, directly affecting the width. 4) the thickness of steel wire or fish wire affects the width. Usually the steel wire becomes wider or the fish wire is thicker, the band will be wider, and on the contrary, it will be narrower. 5) weft feeding problem. If send weft feeding machine screw loosening, resulting in weft round big small and weft stop, and when the spring elastic instability, can cause the width change, school to can correctly, if the filling out of conveyor belt, weft too tight or too loose, make the width change, should readjust the position of the weft conveyor belt; 6) the amount of yarn fed by the coil head and the looseness are caused. Generally, the disc head is loose, the band will become wider, the disk head will be tight, the band will become narrow; 7) the reed is not in conformity. The reed and its compliance will directly affect the finished width. 8) the position of the reed is moved. The reed widens against the wire and Narrows against the lock.
