Description
Technical Field
The invention relates to the field of printing and dyeing industry, in particular to a printing and dyeing additive and a method for dyeing real silk/viscose composite fabric.
Background
The real silk fabric is named as 'fabric queen', the characteristics of smooth and soft texture, high elasticity, bright and soft luster are favored by consumers, and the real silk fabric has excellent dye performance and can be dyed by acid, neutral, direct, active, cationic, reductive, soluble reductive, insoluble azo dyes and the like. However, it is easily damaged in alkaline media, so that acid dyes are generally used as the main materials, and neutral, direct and reactive dyes are used as auxiliary materials.
The common viscose fiber has good hygroscopicity, easy dyeing, difficult static generation and better spinnability. The short fiber can be spun purely or blended with other textile fibers, and the fabric is soft, smooth, good in air permeability, comfortable to wear, bright in color after being dyed and good in color fastness. It is suitable for making underwear, outerwear and various decorative articles. However, viscose is less alkali and acid resistant due to its chemical composition similar to cotton, and is therefore generally not suitable for acid dyes.
Therefore, the real silk/viscose composite fabric needs to consider the different properties of the real silk fabric and the viscose fabric at the same time in the dyeing process, but the characteristics of the real silk fabric and the viscose fabric cannot be considered in the prior art, so that the dyeing effect of the real silk/viscose composite fabric is poor.
Disclosure of Invention
The invention provides a dyeing additive and a dyeing method of a real silk/viscose composite fabric, aiming at overcoming the defect of poor dyeing effect caused by the fact that the dyeing method of the real silk/viscose composite fabric in the prior art cannot simultaneously take the characteristics of two fabrics into consideration.
In order to achieve the purpose, the invention is realized by the following technical scheme:
the printing and dyeing additive comprises a composition A and a composition B, wherein the composition A and the composition B respectively comprise the following components in parts by weight:
composition A: 20-45 parts of urea, 10-15 parts of sodium acetate, 5-10 parts of sodium metaborate, 1-5 parts of potassium citrate, 1-3 parts of xanthan gum and 1000 parts of water;
composition B: 10-30 parts of aminosilane coupling agent, 20-30 parts of deacetylated chitin, 100-200 parts of methanol and 600-800 parts of water.
Further preferably, the composition A and the composition B respectively comprise the following components in parts by weight:
composition A: 30-40 parts of urea, 10-15 parts of sodium acetate, 6-9 parts of sodium metaborate, 3-5 parts of potassium citrate, 1-2 parts of xanthan gum and 1000 parts of water;
composition B: 15-25 parts of aminosilane coupling agent, 25-30 parts of deacetylated chitin, 150-200 parts of methanol and 650-750 parts of water.
Still further preferably, the composition a and the composition B respectively comprise, in parts by weight:
composition A: 35 parts of urea, 12 parts of sodium acetate, 8 parts of sodium metaborate, 4 parts of potassium citrate, 1.5 parts of xanthan gum and 1000 parts of water;
composition B: 20 parts of aminosilane coupling agent, 28 parts of deacetylated chitin, 180 parts of methanol and 700 parts of water.
Preferably, the silane coupling agent is one of gamma-aminopropyltriethoxysilane, gamma-aminopropyltrimethoxysilane, phenylaminomethyltriethoxysilane or N-beta (aminoethyl) -gamma-aminopropylmethyldimethoxysilane.
A dyeing method of real silk/viscose composite fabric comprises the following steps:
(S.1) preprocessing the fabric: soaking the real silk/viscose composite fabric in the solution containing the composition A, and heating for a certain time;
(S.2) modifying the surface of the fabric: adding a certain amount of the composition B into the solution, continuously soaking for a certain time under the stirring condition, taking out the real silk/viscose composite fabric, and drying;
(S.3) dyeing: and (3) placing the real silk/viscose composite fabric subjected to surface modification into reactive dye liquor for dyeing, soaping after dyeing is finished, and drying to finish dyeing.
Preferably, the amount of composition A added in step (S.1) is 1-3% by volume fraction.
Preferably, the treatment temperature in the step (S.1) is 50-65 ℃, and the treatment time is 20-60 min.
Preferably, the amount of the composition B added in the step (S.2) is 1 to 5% by volume fraction, and the impregnation method is two-dipping and two-rolling.
Preferably, the single stirring and dipping time is 10-45 min, the rolling residual rate is 90%, and the drying temperature is 75-85 ℃.
Preferably, the dyeing temperature is 40-50 ℃, and the dyeing time is 30-40 min.
The invention has the following beneficial effects:
the printing additive of the present invention includes the composition a and the composition B, and the functions of both are different. The composition A has a certain alkalescence effect, can destroy hydrogen bonds in viscose fibers and silk fabrics at a certain temperature, effectively improves the permeability, and can be combined with hydrogen bond fracture positions in cellulose by matching with the addition of xanthan gum, so that hydrogen bonds can not be formed again in cellulose molecules. In addition, the addition of the sodium metaborate can also play a certain role in improving the toughness of the fabric, so that the mechanical strength of the fabric during the printing and dyeing pretreatment can be protected.
The composition B is used for modifying the broken part of the hydrogen bond after the hydrogen bond of the fabric is opened, so that the groups which have binding force to dye molecules in the fabric are increased, and the real silk/viscose composite fabric can be better dyed.
The chitosan contains more hydroxyl and amino which are active groups, and the chitosan has good reaction activity with the active dye, so that the chitosan is added and then is combined with the silane coupling agent containing the amino, so that the dyeing effect of the fabric can be effectively improved.
Therefore, in the actual dyeing process, the hydrogen bonds in the fabric are firstly opened through the composition A, so that the fabric is modified by modified molecules conveniently, and meanwhile, the dyeing properties of the real silk fabric and the viscose fabric are estimated, so that the combination of the reactive dye and the fabric is facilitated, and the dyeing effect is effectively improved.
