Abstract
The embodiment of the invention discloses a red active dye composition and a dye product. The dye composition is prepared from any four or five kinds of materials from a compound A, a compound B, a compound C, a compound D and a compound E. The dye composition and the dye product provided by the embodiment of the invention can be realized for a strong alkali resistant boiling one-bath method or bleaching one-bath method and disperse / active identical pulp printing and basic burn-out printing process. The dye composition and the dye product provided by the embodiment have the advantages that theprepared product has the vivid color and luster and high alkali resistance; the dyeing rate is high; the coloring is uniform; the re-dyeing performance is good; the dyeing flow process is greatly shortened; the energy is saved; the efficiency is improved; the sewage discharging is reduced; the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of dyeing, in particular to a red reactive dye composition and dye products. Background technique [0002] Polyester-cotton blended fabrics are currently the main products of textile printing and dyeing factories. Polyester is generally dyed with disperse dyes with dyes and dye products, while cotton fibers can be dyed with reactive dyes, direct dyes, and vat dyes. The traditional dyeing and finishing process of polyester-cotton blended fabrics is a disperse / active two-bath method, that is, washing first, and then over-dyeing cotton, but this process takes a long time and requires repeated neutralization and washing in the process, which leads to The equipment used in the dispersion / activation bath process occupies a large area, the production is time-consuming and power-consuming, and the sewagedischarge is large. [0003] In summary, the dyes traditionally used in the polyester dyeing process have the di...
