Many defects on the greige fabric have certain rules, and it is easy to find the cause of the defects according to the rules. The obvious characteristics of vertical and horizontal defects on the greige fabric provide a quick way to find the root cause of the defects.

Many defects on the greige fabric have certain rules, and it is easy to find the cause of the defects according to the rules. The obvious characteristics of vertical and horizontal defects on the greige fabric provide a quick way to find the root cause of the defects.

The vertical defect caused by the gray fabric at the horizontal fixed position, whether the defect is a missing needle, a pattern needle, an oil needle, a thin needle or a hole, is caused by the horizontal fixed point on the machine that synchronously rotates with the gray fabric. Such as knitting needles, needle cylinders, single jerseys and sinkers.

According to the type of defect, check whether the state of these parts is intact at the corresponding position of the defect, mainly including: whether the needle tongue is crooked, whether the needle tongue rotates flexibly; whether the sinker throat is crooked or has burrs, in the sinker groove Whether the movement is free, whether there are flying flowers in the groove; whether there is deformation or hairiness at the mouth of the needle cylinder, whether the movement in the needle groove of the knitting needle is free.

Lateral defect

The horizontal defect caused by the gray fabric at a fixed vertical position, whether the defect is a missing needle, a flower needle or a hole, the cause of the defect is not to move with the loom, and must be related to a certain path of factors.

Solution

First of all, find any yarn to mark and determine the factors that do not follow the movement of the loom. The factors that do not follow the movement of the loom include the yarn guide, the knitting (including sinker) cam, the yarn used for knitting, and whether the guide hole is worn or not; Whether the cam is loose, whether the pressing needle position is correct; whether the yarn tension is jumping, whether it is consistent with other paths, and whether the strength meets the requirements.
