Description

Yellow active dye composition and its tint applications and method on fiber
Technical field
Tint applications and method the present invention relates to a kind of reactive dye compound and its on fiber.Specifically, originally Invention is related to a kind of Yellow active dye composition and its tint applications and method on fiber.
Background technology
Blended, union possesses the excellent performance of two kinds of fibers, such as brocade/cotton, brocade/binding textiles both have cellulose fiber Good moisture permeability is tieed up, and with good elastic, the excellent wear resistance of polyamide fibre.Fabric feeling is plentiful, smooth, dress Comfortably, high resilience and gloss.Blended, union is currently a popular garment material.
Traditional blended, union carries out two-bath process using a variety of dyestuffs.But there are technological process for this dyeing It is long, energy consumption is big, dyefastness is poor, be also easy to produce aberration, dyeing defect and the problems such as staining.Therefore, using single bath process carry out it is blended, The Study on dyeing of union becomes one of hot spot of current printing and dyeing circle concern.
Homochromatism refers to blended, crossed fiber dying similar form and aspect or tone, and apparent shade depth or color It is close, it is bright-colored degree also close to.Tone-on-Tone Dyeing is blended, union using a kind of most colouring methods.Blended, intertexture The homochromatism dyeing of fabric is a problem in current staining technique.Product poor reproducibility, colour combination is difficult, and rate of returning something for repairs is high, draws Labor cost is played with contaminating the waste of material, the energy.At present, blended, union dyeing and finishing processing is most to use a variety of dyestuffs Two-bath process.This is not only of high cost, and also difficult symbol requires homochromatism sometimes.
It is contemplated that develop a kind of reactive dye compound, the compound can meet to contaminate on single bath process bright and beautiful cotton blend, Union, and homochromatism well etc. requires.
For the present inventor on the basis of a large number of experiments, the selection for confirming dyestuff is the vital factor of the present invention.
