Cross dyeing is "a method of dyeing blend or combination fabrics to two or more shades by the use of dyes with different affinities for the different fibers". [10] The cross dyeing process can be used to create heather effects, and plaid, check, or striped fabrics.
During the dyeing process, the dye must become close and even with the material in order to produce a uniform color that is fast to moisture, heat, and light. [5] Due to their superior fastness properties and simple application, reactive dyes are currently the most common type of dye for cotton dyeing. [6] The CPB technique uses less water and ...
The fabric piece is then moved down from the wound roller, through the dye solution and back onto the other roll. The rollers can be reversed so that the process of unwinding and winding can be done multiple times until the dyeing process is complete. Once the process has finished the dye bath is cooled and the fabric is taken out and dried ...
"Lyocell" has become a genericized trademark, used to refer to the Lyocell process for making cellulose fibers. [ 3 ] [ 6 ] The U.S. Federal Trade Commission defines Lyocell as "a fiber composed of cellulose precipitated from an organic solution in which no substitution of the hydroxy groups takes place, and no chemical intermediates are formed".

The direct spinning process avoids the stage of solid polymer pellets. The polymer melt is produced from the raw materials, and then from the polymer finisher directly pumped to the spinning mill. Direct spinning is mainly applied during production of polyester fibers and filaments and is dedicated to high production capacity (>100 ton/day).
Inkodye is a type of vat dye that uses light rather than oxygen to "fix" the dye, with a wide variety of possible effects. These dyes, which are chemically similar to vat dyes, are developed by light instead of being applied in an oxygen-free bath and being developed in the fabric by exposure to oxygen. Inkodyes are true dyes, not fabric paints.
Reactive dye printing is a method of printing fabrics using reactive dye incorporated into a paste or wax including components such as sodium alginate gum, soda ash, urea and kerosin. Typically, the dye is dried at 130 degrees and cured at 180 degrees to permanently bond it, and the fabric later treated with a softener for better hand feel.
