Many clothes and fabrics are prone to fading during cleaning. Why are many clothes easy to fade, but many clothes are not easy to fade? We consulted the researchers of the textile printing and dyeing laboratory, and analyzed the relevant knowledge of textile printing and dyeing in detail.
Cause of discoloration
There are many reasons that affect the fading of clothes, but the key lies in the chemical structure of the dye, the concentration of the dye, the dyeing process and the process conditions. Steam reactive printing is the most popular generic type of textile printing.
reactive dye steam
In the textile printing and dyeing laboratory, the steam generated by the steam generator is widely used in fabric drying, fabric hot water washing, fabric wetting, fabric steaming and other processes. In the reactive printing and dyeing technology, steam is used to combine the active gene of the dye with the fiber molecules, so that the dye and the fiber become a whole, so that the fabric has good dustproof function, high cleanliness and high color fastness.
steam drying
In the weaving process of cotton fabric, it must be dried many times to achieve the effect of color fixation. Considering the low cost and high efficiency of steam, the laboratory puts steam into the research of weaving technology. Experiments show that the fabric after steam drying has good shape and good color effect.
The researchers told us that after the clothes are dried by the steam generated by the steam generator, the color is very stable and usually not easy to fade. Reactive printing and dyeing does not add azo and formaldehyde in the textile printing and dyeing process, has no harmful substances to the human body, and does not fade when washed.
Novus printing and dyeing fixation steam generator is small in size and large in steam output. Steam will be released within 3 seconds of activation. The thermal efficiency is as high as 98%. , Cloth and other solid color options.
