(1) Wrong Yarn
Exterior: In the hairs of knitted fabrics, transversely continuous terry loops are woven from coarser or finer yarns than those of standard yarns. Generally, they are generally single, but even those that are juxtaposed or spaced are more compact and thicker. Normal people are different.
Causes: When weaving knitted fabrics, operators mistakenly use non-specified yarn counts or denier yarns to weave misuse of finer yarns. As a result, fabrics appear thinner and misuse of thicker yarns.
(2) Wrong End
Appearance: The warp of the woven fabric has a single or side-by-side number of non-specific specifications. If it is a fine yarn, it is called Fine End. If it is a thicker yarn, it is called Coarse End.
Contributing factors: The number of bobbin yarns involved in the warping of menstruation during the warping period is wrong, and the use of warp yarns of non-specified specifications is often the case of full-match persons.
(3) Wrong Pick
Appearance: The weft of the woven fabric has one or more non-specified thicknesses. For finer yarns, FinePick is called. If it is a thicker yarn, it is called coarse weft.
Causes: When weaving, the weft yarn of the weft tube, or the number of bobbin yarns fed by the shuttleless weaving machine is wrong. It is not easy for the weaving machine that uses the non-specified weft yarn operator to remove and stop the machine after it is found and then automatically changes the tube. Find.
(4) Wrong Weaving
Appearance: The weave method is wrong. The texture of the fabric is different from the original designer. For example, the left twill weaves into the right twill.
Causes: Most of the errors are due to mistakes in jacquard fabrics, errors in warp yarn arrangement in multi-standard warp fabrics, etc.
(5) Wrong draw
Exterior: The two warp yarns that are adjacent to each other are regarded together as one woven into the cloth by the fabric organization. The root (actually two) yarns appear to be particularly thick. When the initial weaving of the shaft is found, the elimination of one of the roots can be completely avoided.
