Description
DN rare-earth additive involved in the present invention is to be many components, the multifunctional dyeing auxiliary agent of Main Ingredients and Appearance with the macromolecule rare-earth complex.
Prior art in the prior art of the present invention field is:
On the current international market in " back to nature " in vogue still, leather and fur products is required to have the natural stype of " thin, light, soft ".Thereby the wherein thin natural graining that is meant thin coating maintenance leather, this just requires will redye dab on the leather processing technology, be coated with and dye combination; Especially suede, water dye to remove from office to redye and are not coated with, and this has just proposed new higher requirement to leather coloring.
The present used proprietary dyestuff rareness of leather industry, and acidity, direct dyeing fastness commonly used are poor, tone is not full, and dye dosage is big during dyeing, the cost height, chroma in waste water is dark.Be difficult to dye dark-toned leather when particularly the crust leather after the retanning of anionic acrylic resin retanning agent is with anionic acidity, direct dyeing, particularly dye the black leather.This has just hindered the extensive use of acrylic resin retanning agent in leather retanning.
Acrylic resin retanning agent is one of important retanning material of leather.It has been subjected to process hides worker's welcome since coming out always.During China's the 8th Five-Year Plan for national economic and social development with acrylic resin retanning agent as key popularized project.But, be difficult to dye dark-toned leather, particularly black leather during direct dyeing because the acrylic resin retan is with acid; And black is because historical reasons is lasting on market.Therefore, this colouring problem is troubling leather worker both at home and abroad always, and to this, the leather worker has done a large amount of work both at home and abroad, also obtains certain achievement, but does not fundamentally solve.Many researchers once used various means to strive capturing the global problem that this leather industry faces jointly both at home and abroad, as the exploitation ampholytic acrylic resins retanning agent; With slaine preliminary treatment acrylic resin retanning crust leathers such as hexamethylenetetramine, ammonium sulfate and alum; Germany Hoechst company has human ACID DYES and basic-dyeable fibre to match to solve the colouring problem of resin retan.All these measures have certain effect, but see all undesirablely from the indexs such as dye-uptake of dyefastness, gorgeous degree and dyestuff, do not get a desired effect; And some method also increases cost suddenly, operates also rather loaded down with trivial details.
Purpose of design of the present invention is:
Dyeing is the important means of beautifying leather.Different crust leather states and kind have nothing in common with each other to the requirement of dyeing, also have many problems.Design of the present invention is primarily aimed at the problem of the following aspect of dyeing process in the curriery:
(1) colouring problem of solution acrylic resin retanning crust leather.
Retanning is called as " Golden Touch " in leather industry, and acrylic resin retanning performance in retanning agent is the best, is described as miracle type retanning agent, is China's " the Seventh Five-Year Plan " scientific achievement.But the existence of a large amount of carboxyls has a strong impact on the combination of crust leather to subsequent handling dyestuff and fatting agent in the big molecule of acrylic resin, and the crust leather surface colour is light, and especially " dying and deceive " becomes distinct issues.
The colouring problem of using DN serial rare-earth auxiliary agent to solve acrylic resin is incomparable with other any materials and method.DN serial rare-earth auxiliary agent can change the electriferous state of crust leather, improve of the absorption of resin retanning crust leather to anionic dyestuff and fatting agent, resin retanning crust leather with the processing of DN series auxiliary agent, the leather color of being dyed is pure, tone is full, bright-coloured, has solved the colouring problem of acrylic resin retanning crust leather, even it is also very good to dye the black effect, reached the degree that chromium retanning crust leather dyes black, some index has also surpassed the chromium retan.
(2) improve dyefastness, reduce dye dosage, simplify production technology.
" thin, light, soft " is one of important trend of leather products, for the various garment grain leathers that needs are covered with paint, lacquer, colour wash, etc., redyes dab and is and improve the quality and the fine way of class; For the suede garment leather of not covering with paint, lacquer, colour wash, etc., then higher to the dyeing requirement, not only require color and luster full, pure, but also need good fastness.
DN serial rare-earth auxiliary agent is used for leather coloring, its level dyeing, the effect that increases dark and fixation are all fairly obvious, can play and prevent the look flower, the leather color even of being dyed, pure, tone is full, bright-coloured, has improved the dye-uptake of dyestuff to leather, can improve dyefastness 0.5-1 level, save dyestuff 10-25%, the secondary dyeing (chromatography) of suede garment leather can be changed into once dyeing, simplified production technology.
Design of the present invention:
The present invention synthesizes the macromolecule complex body earlier, then with itself and rare earth complex, and composite again other material, thus synthesize the rare earth high polymer complex compound.
1, rare-earth additive help that to dye function as follows:
A. the macromolecule complex body is synthetic:
Anionic dye (acid, direct dyestuff) and crust leather fiber are mainly with the electrovalent bond combination, and the electrovalent bond adhesion is not strong; Moreover it is not the sulfonic group isoreactivity base hydrophily of dye molecule is strong, thereby water-fast.Desire improves colorfastness, must improve the bonding state of dyestuff and fiber.
Sulfonic group effect among middle ortho-nitrogen ion and the D-SO3H is played tint retention, simultaneously
Can play the effect of regulating molecular weight.
Have among product B in reaction (2), (3), the C-NH-,-the nitrogenous active group of NH2, under the low situation of pH value, do not show electrically; When under the high situation of pH value, become
,
Thereby can react with anionic dye like this and generate the color lake.
Product B, C and the combination of acrylic resin retan in reaction (2), (3) increase its cation group, help like this dying on the anionic dye.
The HOCH2CH2OH of reaction in (4), can regulate positive charge in the strand, avoid simultaneously that crosslinked to cause into grain excessively by force coarse.
B. graft reaction
In the grafting
After, product C, F more help the chromium in the chrome leather to carry out coordination, are simultaneously and rare earth ion increase complexing power.
C. with the complex reaction of rare earth ion:
More than each product can with rare earth ion generation complex reaction, thereby form rare-earth complex.The hapto that complexing takes place is-NH
2,-OH ,-COOH isoreactivity group.
Like this, delocalization effect takes place with dyestuff, the crosslinked multicomponent system of having formed of fiber in rare-earth complex, so maximum system energy descends, absorbing wavelength moves to long wave, and hyperchromic effect takes place.Moreover increase the dyestuff binding site, and increase the dyestuff dye-uptake, absorption peak is strengthened, make color and luster dense.The rare earth complex ion causes the dyestuff absorption spectrum to narrow down simultaneously, makes the finished leather tone full, pure.
