What are active fabrics and semi active fabrics, please?
Reactive fabrics and semi reactive fabrics mainly refer to the way of dyeing and printing.Reactive printing is also known as reactive dyes. It contains an active gene that reacts with fiber molecules.
Semi active printing is also called semi active dyeing and printing. Semi active dyeing and printing is not adding azo and formaldehyde in the process of dyeing and printing, and it does not contain substances harmful to human body, and it doesn't fade or shrink when washing. The difference between the activity of printing and dyeing and coating printing and dyeing of reactive dyeing of soft feel slippery, the common argument is that the reactive dyeing of mercerized cotton fabric looks like, from the two aspects of positive and negative view of dyeing effect is very good; and the paint dyeing fabrics feel stiff, looks a bit like the ink painting effect.
The active dyeing makes the fabric dustproof, with high cleanness and high color fastness. Of course, the cost is much higher than pigment printing and dyeing. Is the stamp dyes used for reactive dyes, generally used in high viscosity sodium alginate paste do flow (which degeneration small, small amount of slurry infiltration, can better keep the original pattern, mostly used) M type reactive dyes was (the dye has good fixation rate and lifting force, also can reduce the soaping staining prescription / 9 L 'reactive dye x urea 1 2x reservehao S 10 material amount of water amount of alkali 15 - 30). Compared with pigment printing, active printing has many advantages, such as good permeability, excellent color fastness and soft feel, but there are also many problems, such as complicated printing process, long process and difficult processing. General active printing and dyeing can guarantee environmental protection, harmless to people, color and fabric feel is better, there will not be a hard, soft feeling.
In the process of dyeing and printing, the active genes of dyes combine with fiber molecules to form a whole of dyes and fibers. Make fabric dustproof, good performance, high cleanliness, long wash, not fade. The colour is bright and will not fade.
