Structural composition and practical effect of damper pre-shrinking machine

May 17, 2019

Damping pre-shrinking machine is a pre-shrinking machine for thin knits, elastic ribs and other circular knits. It consists of three parts: steaming wet, damping pre-shrinking and cloth. The circular knit fabric enters the steamer steam through the expansion roller, the super-feed roller and the struts to help the final pre-shrinking effect.


The pre-shrinking part of the damper type pre-shrinking machine has two sets of damping pre-shrinking devices to meet the needs of the two-side pre-shrinking of the circular knit fabric, and each group consists of a feeding roller, a damping blade and a retarding roller. The feeding roller has a smooth surface and the roller surface of the retarding roller is rough. The line speed of the retarding roller is lower than that of the feeding roller, so that the fabric is pressed against the feeding surface of the damped blade and then enters the rolling point of the two rolls, and is pre-shrinked by the damping of the retarding roller.


The amount of squeezing between the two rolls of the damper type pre-shrinking machine is controlled by adjusting the line speed of the two rolls, and the two rolls are heated by steam, the damper blade is electrically heated and the pressure applied to the fabric is controlled by a pneumatic device. The damped pre-shrinked fabric is conveyed by the curtain belt to the drape device for folding. Practice has proved that the pre-shrinkage rate of the damper type pre-shrinking machine is 0~25%, which can be adjusted as needed; after pre-shrinking, the cloth surface is flat, the door width is stable, the hand feel is soft, and the shrinkage rate can be less than 1%.


Many manufacturers will buy this kind of equipment, because the benefits of using it are many, and many of the functions are very simple and fast. The safety factor of the damper type pre-shrinking machine is quite high. As long as it is operated correctly, there is no danger. Therefore, the correct operation of the equipment is particularly important, and the operation of the pre-shrinking machine is very simple, as long as it is not in trial operation. In the case of a problem, slowly increase the speed.www.haida-textile.com
