In the textile industry, cotton knitting is a small classification. Here are some common cotton knitting problems.
1, color difference (cylinder difference)
The same color difference between different cylinders of cotton fabric.
2, from the horizontal
When weaving, horizontal stripes appear on the surface of the fabric due to uneven yarn tension or poor equipment.
3, broken needle
During the weaving process, small holes are formed in the weaving due to damage to the knitting needle or damage to the hook.
4, missing needle
During the weaving process, one needle or several needles cause a straight or scattered neutral on the fabric due to the needle loop falling off, but the needle loop is not broken.
The cloth surface has similar scratched marks of different colors.
The surface of the cloth is dirty due to dye or other machine causes.
7, the hole
The size of the hole in the fabric due to weaving and processing.
The fabric is hooked up by a machine or other sharp object during weaving or dyeing
9, flying flowers
During the weaving process, as the flying cotton batt falls onto the woven yarn, the cloth surface exhibits a sliver in the dispersed small yarn group.
10, oil road
Adding oil or changing the needle during the weaving process causes the fabric to be vertically yellow and black.
11, oil points
Adding oil or changing the needle during the weaving process causes the fabric surface to have small round dots.
Because the rotation speed between the yarn picking rolls of the loom is lower than the reasonable requirement, the yarn tension of the knitting needles is not uniform, so that the tightness of the cloth loops is inconsistent, and the diagonal stripes appear on the cloth surface after dyeing.
13, yarn knot
When the yarn is connected, the end of the thread stays too long or the knot is too large, and the fabric has small bumps or small ridges on the cloth surface.
14, dead cotton
Since the cotton fiber is not long matured, the fiber inclusion is too tight, the dye is difficult to be colored during dyeing, and the cloth surface exhibits irregular small color spots after dyeing.
15, broken yarn
During the weaving process, the cotton yarn (or the pull frame) breaks, causing the back knitting needle to be unable to eat the yarn (or the pull frame) to form a broken coil.
