Now most of the textile and garment factories are the use of fabric rolling machine on the garment material pre-shrinkage operation. But it involves how to manipulate the amount of pre-shrinkage, understand this to better grasp the operating principle of the whole device. In this paper, we briefly analyze it.
Now most of the textile and garment factories are the use of fabric rolling machine on the garment material pre-shrinkage operation. But it involves how to manipulate the amount of pre-shrinkage, understand this to better grasp the operating principle of the whole device. In this paper, we briefly analyze it.
Rolling machine fabric in the dyeing and finishing process is often in the warp direction stretching situation, so that the fabric warp direction elongation weft direction shortening, so that the production out of the products after the shrinkage rate is very high, so through this pre-shrinkage treatment can become products. In addition, the shrinking machine generally consists of feeding, wetting, heating, weft stretching, three-roller pre-shrinkage, loose drying, cloth and other units.
And the pre-shrinking processing mainly ends on the three-roller shrinking machine. When the fabric enters the contact surface of the heating roller and the rubber blanket, due to the shortening effect of the inner side of the rubber blanket, the fabric immediately above it is shortened together and ironed by the heating rod, arriving at the pre-shrinkage boarding effect.
Obviously, due to the special processing technology of the fabric rolling machine, the front and rear of the two units between the machine does not allow the installation of the elastic frame and other detection links, and in order to arrive at a predetermined amount of pre-shrinkage, it is necessary to correctly manipulate the pre-shrinkage unit of the fabric into the fabric speed and out of the fabric speed of the difference in speed, and then end the process required by the control of the amount of pre-shrinkage.
