1. Leakage needle refers to the defect formed by the partial knitting needle in the knitting process due to certain factors, in one or more courses, which can not normally eat yarn into loops.
There are two types of missing needles:
1. Leaking the needle: refers to the missing needle on the opposite side of the cloth. The main reason for the formation: the position of the yarn feeder is too high or too late, the dial code is pressed too deeply, the food position is too minute, the tension of the yarn is loose, the tension of the cloth frame is loose, and the yarn is worn through the wrong yarn. Generally, the food is worn low and the sorghum is worn.
2, the needle is missing: often refers to the leaking needle on the front of the cloth. The main reason for the formation: the position of the yarn nozzle is too high, too far or too open (refers to the position of the needle under the distance of the yarn needle), the tension of the cloth frame is loose, the tension of the yarn is loose, and the food position is too minute. The yarn is worn through the wrong yarn nozzle, and the cloth structure is too sparse.
2, blasting refers to the fabric or yarn in the weaving process, a certain strength is too large, so that a yarn or a few yarns on a needle or a few needles break the yarn to form a defect.
The main reasons for the formation are: the tension of the yarn is too tight, the tension of the cloth frame is too large, the food position is too high, the code of the upper needle is too sparse or too dense (the needle cannot be smoothly uncoiled), and the yarn nozzle is too close or too The yarn is broken by the knitting needle, the barrel of the syringe is too high, the structure of the fabric is unreasonable (the cloth is too sparse or too dense), and the tension of the cloth frame is too loose (so that the fabric cannot be pulled out smoothly in the looped area) The floating cloth exploded.)
Leaking needles and blasting are difficult to distinguish at some time. Usually, the sputum is cut and disassembled for analysis. The broken yarn is broken, and the broken needle is broken.
3, from the horizontal
1. Yarn cross: reject the wrong yarn, coarse yarn, yellow white yarn, misplaced yarn storage device
2, sparse and horizontal: mainly the upper needle code is not uniform, the tension is uneven
3, machine horizontal: the syringe, the needle plate position, the three-fork position, the needle or the gap between the dial and the angle seat is too large or too small, the conveyor has problems, the conveyor plate, the auxiliary wheel has problems.
4, the flower point Mainly refers to the defects caused by the old coil can not be smoothly removed during the knitting process.
The main reasons for the formation: the dial code is too dense, the cloth frame is too loose, the food position is too divided and related to the fabric structure
5, other defects: bite single, over the bottom, fly pull frame, straight drop pull frame, needle path, food pull frame, pinch marks, stop marks and so on.
Method of adjustment: First of all, we must analyze the main reasons for the formation of certain defects. According to the actual situation of the machine, we can check the specific factors that form the defects, and then analyze and adjust, so that the problem can be solved smoothly.
