Analysis of the Causes of Dense Roads in Fabrics
Jul 21, 2018

Fabric thin roads are one of the most common defects in fabrics. One of the reasons for the dense road of fabrics is that some weaving machine delivery mechanisms use mechanical let-off devices. Due to the long transmission chain of the warp mechanism, the mechanism is complex, the system response characteristics are poor, the warp tension control sensitivity and response are limited, and the dense road is generated when the vehicle is parked, and these defects affect the fabric quality. The needle looms equipped with electronic let-off devices play a very important role in preventing downtime and improving product quality.

For the webbing machine using the mechanical let-off mechanism, the reason why the fabric produces a dense road is that when the fabric breaks down, such as breakage, the automatic weft-seeking device of the loom processes the weft, and at this time the delivery mechanism cannot Inverted, so the boot will inevitably produce a thin file. After the loom is parked, the weaving mouth will swim because the warp tension and fabric tension are not balanced. If the position of the weaving mouth moves toward the back of the machine, a dense road defect will be formed when the vehicle is re-driving, otherwise a thin road defect will be formed.
