Wales are stripes that appear on the fabric surface during a machine's operating cycle, characterized by periodic changes in the size of the coils. Generally, the likelihood of raw materials causing wales is low, with the issue more often attributed to the periodic tension irregularities resulting from the timely adjustment of mechanical wear, which then leads to the formation of wales.
The causes are as follows: a. Due to poor installation accuracy or severe wear from equipment aging, the horizontal and concentricity deviation of the circular machine needle tube exceeds the allowable tolerance. Common issues include excessive gaps between the positioning pin of the drive large gear disk and the locating slot of the machine frame, resulting in an unstable operation of the needle tube and severely affecting yarn feeding and circle removal. Additionally, equipment aging, mechanical wear, and increased radial and axial oscillation of the main drive gear disk exacerbate the deviation in the needle tube's concentricity, causing fluctuations in yarn tension, abnormal coil sizes, and, in severe cases, visible horizontal stripes on the grey fabric.
b. During the production process, foreign objects like flyings are inserted into the variable plate slider of the yarn mechanism, affecting its roundness. This results in abnormal speed of the synchronous toothed belt and unstable yarn feeding, leading to the formation of hidden horizontal stripes.
c. The circular loom utilizes a negative-style yarn feeding mechanism, which has the drawback of significant yarn tension variations during the feeding process, easily causing unexpected elongation of the yarn and inconsistencies in yarn feed, leading to hidden horizontal stripes.
d. The round machine with an intermittent winding mechanism experiences significant tension fluctuations during the winding process, leading to potential differences in the length of the coils.
