Pigment print: dut to the coating is a non-water-soluble coloring substance, no affinity for fibers, its coloring rely on the film-forming polymer compounds coating and adhesion to the fiber to achieve. pigment print can be used for the processing of any fiber textile, in the mixed, interwoven printing is more superior, and the process is simple, the color spectrum is wider, design is clear, but the touch feeling is not good, friction fastness is not very high. pigment printing is a direct printing of paint, a process commonly referred to as dry printing, to distinguish it from wet printing (or dye printing). Their light-resistant and dry-clean fastness are good, even excellent, so they are widely used in decorative fabrics, curtain fabrics, and clothing fabrics that require dry cleaning.
If the fabric base color is the same depth on the front and back (because it is dyed), and the print pattern is much darker than the base color, then this is the cover fabric, otherwise, it is white background printing.
Dispersed dye, a dye that is slightly soluble in water and highly dispersed by means of dispersant in water. Dispersed dyes do not contain water-soluble groups, the molecular weight is low, although the molecule contains polar groups is still a non-ion type dye. These dyes require high post-treatment requirements and usually need to be ground by a grinder under the presence of dispersants to become highly dispersed, crystal-stabilized particles before they can be used. The dye that disperses the dye is a uniform and stable suspension.
1, light-resistant colorfastness: The color of a textile is resistant to artificial light.
2, wash-resistant colorfastness: The resistance of the color of textiles to the washing effect of different conditions.
3, friction-resistant colorfastness: The color of textiles is resistant to friction and can be divided into dry and wet friction fastness.
4, resistant to sublimation colorfastness: The degree to which the color of a textile resists heat and sublimates.
5, sweat-resistant colorfastness: Textile color resistance to human sweat, according to the acidity of the test sweat, can be divided into acid, alkaline sweat stain fastness.
6, smoke-resistant fade fastness: The color of textiles resists the ability of nitrogen oxides in the flue gas. Dispersed dyes, especially quinone structure, encounter nitric oxide, nitrogen dioxide, dyes will produce discoloration phenomenon.
7, heat-resistant pressure colorfastness: The color of the textile resists ironing and roller processing.
8, dry hot colorfastness: The color of the textile resists the ability of dry heat treatment.
