Wide width linear plasma cleaning machine plasma treatment of flax fabric dyeing:

 

Flax, ramie and other hemp fabrics with good permeability, cool, comfortable and other properties, by the majority of consumers like. However, because of the high degree of crystallinity and orientation of hemp fabric, the dye is not easy to infiltrate and diffuse, and the poor dyeing performance is not easy to dye into dark color, which limits the application of flax in high-grade fabrics to a certain extent. In the past, the dyeing properties of flax fabrics were improved mainly through cationic chemical modification, chemical grafting, rare earth method, coating method, adding darkening agent, etc. These methods have certain effects on the dyeing properties of flax fabrics. However, there are some disadvantages such as high cost, high water consumption, high energy consumption, environmental pollution and destruction of fiber performance.

Wide width linear plasma cleaning machine Plasma surface treatment:
The surface etching, weight loss and roughness of the fabric can be increased by oxygen plasma treatment with wide-width linear plasma cleaning machine. The surface of the fabric has microholes and cracks. The surface area of the fabric is increased. When oxygen plasma is used to treat flax fabric, oxygen atoms are infiltrated into the fiber surface, generating free radicals and causing oxygen radical reaction in the air. Such hydrophilic groups as hydroxyl group, carbonyl group and peroxy group are introduced to improve the hydrophilicity of fabric. The higher the treatment power, the more high-speed particles, the greater the energy, the more serious the bombardment etching effect on the fiber surface, the lower the crystallinity of the fiber surface, so as to improve the wettability of the fabric, which is conducive to the improvement of the dyeing concentration of the fabric.

 

Improving the etch roughness and wettability of fiber surface can improve the colouring rate and colouring depth of fiber. The increase of the dyeing rate is directly related to the wettability of the fabric. The better the wettability is, the more conducive it is to the penetration and diffusion of the dye into the fiber, thus increasing the dyeing percentage. The bombardment and etching of high energy particles on the surface of ramie fiber increases, which leads to the repeated reflection and absorption of the fiber surface, increases the total absorption of the fiber to the incident light, and produces the apparent dark effect. Wide width linear plasma cleaning machine plasma treatment is beneficial to improve the direct dye dyeing of flax fabric wash and wear resistance, can replace the color fixing agent Y for color treatment, reduce the consumption of chemical agents.

 

For the resin or linen fabric softener finishing, after wide linear plasma cleaning machine, plasma treatment, the fiber surface was etched, can make the fiber and finishing agent, further in the fiber surface to form a layer of a solid coarse layer, greatly reduces the light reflectivity of fiber surface, enhances the deep dyeing of fabrics.
