Wuxi Highness Technology Co., Ltd

Pre-treatment is sufficient, the fabric wetting is good, the capillary effect is large, the dye molecules on the dye diffusion capacity is likely to increase, thereby increasing the dyeing rate. So to strengthen the impurity removal, decontamination treatment, can achieve the above objectives.

 

2 mercerized treatment of cotton fabric

After the mercerized cotton fabric, the dye adsorption capacity of the cotton is significantly higher than that of the cotton fabric without the mercerization, and the surface gloss is improved.

 

3 Polyester fabric alkali reduction treatment

Polyester macromolecules high crystallinity, fiber structure, refractive index and surface reflectivity are high, the fiber surface is smooth, the light to reflect the main mirror, with a disperse dye dyed black, because a lot of reflected light from the fabric surface to white Light into the human line of sight, so dark black more difficult to obtain. After the alkali reduction treatment, the original smooth surface of the polyester into a rough surface, the formation of irregular irregular reflection layer, that is, we often say that the etching effect, and produce a certain dark effect, and after the reduction of fabric Increased degree of freedom of movement, the adhesion of the dye has increased.

 

4 low temperature plasma technology

Plasma technology is a method of processing on the surface of the fabric, is a modern dyeing technology of dry cleaning physical processing. For example, after the plasma treatment of polyester fiber by graft polymerization, the formation of low refractive index film on the fiber surface, can significantly improve the dye uptake rate and color depth; and as difficult to dye the linen fabric with plasma treatment, the fabric Capillary effect is untreated 1 ~ 1.5 times, greatly increased the amount of dye adsorption, easy to dye deep dark color, dark effect is obvious.

 

5 Ultrasonic technology processing

Ultrasound is the human ear can not perceive the vibration wave, the normal frequency of 104 ~ 109Hz sound called ultrasound, and the frequency is greater than 109Hz called special ultrasonic or microwave ultrasound. Fabric dyeing before the ultrasonic treatment, the degree of fiber concentration is loose, so that the internal surface area of ​​the fiber increases, thereby increasing the amount of fiber adsorption on the dye to improve the dyeing rate of the fabric, to obtain the dark effect The The study, this technology has a scaly layer of wool fibers and surface structure of the linen fabric effect is obvious.
