One, tight
The warp pattern of woven fabrics is relatively straight and the interweaving point is concave into the cloth surface. This phenomenon is called tight warp. This kind of situation is more obvious in twill and Poly Spandex fabric. In severe cases, it can also cause unevenness.
Reason analysis: the tension on one of the warp yarns is too high during weaving or the joint is pulled too tightly after the warp yarn is broken.
Two, tight weft
The phenomenon of a weft yarn in the pattern of woven fabrics is relatively straight and the interweaving point is concave into the cloth surface is called tight weft. But such defects are rare, and even if they are, they are not obvious.
Reason analysis: this kind of situation occurs when the weft thread is not smoothly retreated or the retreat is not smooth, and the tension is too large when weaving.
Three, different classics
When the warp yarn of woven fabric has a single or several non-specified thick and fine yarns in parallel, the phenomenon of different warps will appear.
Reason analysis: When warping, the yarn count of the yarn used for drawing is wrong or the warp yarn of non-specified specification is used.
Four, side support marks
There are about 2-5 cm wide needle punches or traces drawn by needle punches in the edge of the woven fabric, which can cause the weft yarn in this part to bend in a wave shape.
Reason analysis: improper thickness of the needle used in the temple and the stuck ring of the temple cannot be rotated.
