A kind of fiber covering layer and roll with it and both manufacturing process

Abstract

The invention relates to the technical field of rolls, more specifically, it relates to a fiber covering layer, a roll with the same and a manufacturing process for both. A roll with a fiber coating layer includes a roll body, and the material of the roll body is iron. The outer layer of the roller is covered with a fiber covering layer, and the fiber covering layer is formed by splicing and pressing several sections. The fiber covering layer is made by mixing nylon fiber, polyester fiber and aramid fiber, and the ratio of the three is 3.5‑4:3.5‑4:2‑3. The fiber covering layer of the present invention can increase pores and store printing and dyeing liquid, and the liquid carrying rate of the cloth after printing and dyeing of the present invention is only 15%-30%. The fiber coating layer of the present invention can increase pores, store printing and dyeing liquid, and when the cloth is pressed by rollers, the dyeing penetration rate of the cloth can be improved, pigment waste can be avoided, environmental protection and resources can be saved. The fiber coating layer and roll of the present invention can bear a heavy ton, which can reach 20kg.

Description

technical field [0001] The invention relates to the technical field of rolls, more specifically, it relates to a fiber covering layer, a roll with the same and a manufacturing process for both. Background technique [0002] With the development of printing and dyeing technology, printing and dyeing equipment and key accessories are also gradually upgraded. At the same time, people have put forward higher requirements for the quality of various printing and dyeing products. As a key accessory of printing and dyeing equipment, printing and dyeing rubber rollers are directly in contact with printing and dyeing products. Its quality reliability directly affects the quality of printing and dyeing products. [0003] The invention patent with the publication number CN105437816A discloses a printing and dyeing rubber roller cover for printing and dyeing machines, including the rubber roller cover body and a reinforcing layer, a dyeing layer, a buffer layer, a hydrophilic layer and a...

AI Technical Summary

Problems solved by technology

[0005] 1. Use rubber material, the retractability of rubber material is not good, and the service life is limited;

[0006] 2. There is another problem with the rubber material. When printing and dyeing, it is necessary to apply pressure to the two rollers to increase the dyeing penetration rate of the cloth. However, when the pressure is slightly higher, once the rubber sleeve is aged, the rubber sleeve is easy to break and break;

[0007] 3. In addition, the friction coefficient between the two rubber rollers is low, which will easily lead to a decrease in the penetration rate of the cloth dyeing, and the thicker cloth will not be dyed through;

[0008] 4. When using rubber rollers for printing and dyeing, the amount of liquid on the surface of the fabric is still high, and more dyes are consumed, which is not energy-saving and environmentally friendly
