Description

Be applicable to the covalent bond colorize method of silk
Technical field
The present invention relates to a kind of covalent bond colorize method that is applicable to silk.
Background technology
There is the not good problem of dyefastness in silk fiber, the existing silk fiber colouring method that is applicable to respectively has deficiency.Synthetic dyestuffs for dyeing silk mainly contain ACID DYES, premetallized dye and REACTIVE DYES at present.Although ACID DYES is bright in colour, chromatogram is complete, dye-uptake is high, it is combined with silk fiber by ion bonding force, is vulnerable to the solvation impact of water, and moisture resistant fastness is not good conventionally.Premetallized dye forms complex compound by acting on fiber of metal (chromium, cobalt) ion, has good moisture resistant fastness, but in fiber and dye liquor, a large amount of residual meetings of metal ion cause negative effect to health and environment.In REACTIVE DYES structure with reactive group, during dyeing, can react with the amino of silk fiber macromolecular chain end and the phenolic hydroxyl group in tyrosine residue and generate covalent bond and dying on fiber, yet the covalent bond forming between REACTIVE DYES and protein fibre mostly is ester group and amide groups, hydrolysis scission of link easily occurs in stronger acid, alkaline media, and REACTIVE DYES also cannot thoroughly solve the moisture resistant fastness problem of silk fiber thus; In addition, exist serious hydrolysis problem in reactive dye color fixing process, produce a large amount of colorful wastewaters, sewage disposal difficulty is large.Therefore, designing and a kind ofly can form firm covalent bonds with silk fiber, make it have excellent moisture resistant fastness, and reduce blowdown flow rate, is dyeing and finishing industry problem in the urgent need to address.
Silk fiber dyeing be take water conventionally as medium, and dye molecule enters fiber amorphous region and amino acid forms physics or chemically combined process, and the morphosis of its dyeability and fiber, aggregated structure, amino acid form closely related.Silk consists of fibroin and silk gum two parts, and the fibroin fiber degree of crystallinity after natural silk degumming is high, and it is few that amino dyes seat, and depth is poor.In forming the amino acid of silk fiber, only have tyrosine to contain phenol formula structure, not only content is high, and is mainly distributed in the easy fiber amorphous region of infiltrating of the aqueous solution.For example, the tyrosine residue molar content of Bombyx mori Silk Fibroin, tussah silk peptide is respectively 0.65 and
0.48m mol/1g fiber, the seat demand of dying of dying to dark heavy colour pool fiber that surpasses far away.
The chemical modification of protein side group is a kind of important method of improving Sporal Protein Chemical Properties.Can there are three components with aldehyde material, aryl primary amine and derivative thereof and react in the tyrosine residue in protein or polypeptide, make three kinds of materials by covalent bond strong bonded under gentle condition, and this class reaction is called Mannich reaction.
This seminar once applied for " a kind of colouring method of protein material " (201010039595.3), the method is to utilize tyrosine residue in protein fibre material as coupling component, and the method for using for reference ice dyeing dyeing develops the color different diazols and the tyrosine residue generation coupling reaction in protein fibre.The method is equally also applicable to the painted of silk fiber, and moisture resistant fastness is excellent.But the method is because coupling component is single, obtain dark difficulty, be only applicable to the painted of Huang, orange, the light silk fiber such as red.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly can forms with silk the dye coloring method of firm covalent bonds----a kind of covalent bond colorize method that is applicable to silk.
In order to solve the problems of the technologies described above, the invention provides a kind of covalent bond colorize method that is applicable to silk: the dyestuff containing aryl primary amine group reacts with the tyrosine residue generation Mannich in silk under the effect of aldehyde material, thereby dye molecule is firmly connected in the large molecule of silk;
Described is 0.005~0.03:1 containing the dyestuff of aryl primary amine group and the mass ratio of silk, containing the dyestuff of aryl primary amine group and the mol ratio of aldehyde material, is 1:1~2; Dye bath ratio is 1:20~100; Value in Dyeing Process remains in 4.0~6.5 scopes, dyeing temperature is 30~70 ℃, temperature retention time 0.5~24 hour, after dyeing finishes, then for example, through superheated water and cold water washing (being the deionized water washing through 60 ℃ and 15 ℃), thereby remove the impurity (washes clean from silk by dyestuff loose colour and aldehyde material) being adsorbed on silk, dry (under the room temperature of 10~25 ℃, drying in the air to constant weight).
Remarks explanation:
With the cushioning liquid of acetic acid-sodium acetate, regulate above-mentioned pH value, this is routine techniques.
The above-mentioned dyestuff containing aryl primary amine group, at least needs to exist an aryl primary amine in described dye structure.
As the improvement that is applicable to the covalent bond colorize method of silk of the present invention: aldehyde material is formaldehyde, acetaldehyde, propionic aldehyde, butyraldehyde or benzaldehyde.
As the further improvement that is applicable to the covalent bond colorize method of silk of the present invention: the described dyestuff containing aryl primary amine group is following any one dyestuff:
