The present invention relates to a kind of acid amides based polyurethanes suede-like artificial leather manufacture method be easy to and dye, it is to use Amide based solvents type polyurethane resin to configure to cover with paint, lacquer, colour wash, etc. slurry, then slurry will be covered with paint, lacquer, colour wash, etc. to cover with paint, lacquer, colour wash, etc. in suede-like artificial leather scrim surfaces, the polyurethane suede-like artificial leather for being dyeed by dyeing treatment again, covering with paint, lacquer, colour wash, etc. slurry includes the component of following mass parts：100 parts of Amide based solvents type polyurethane resin, 20~120 parts of dimethylformamide, 20~120 parts of acetone.Amide based solvents type polyurethane resin is used as artificial leather top finishing material, dyeing process can be carried out with dyestuff, color effects by that can obtain dyestuff coloring after dyeing treatment, make product have the characteristics of bright-colored, coating permeability is good, surface color fastness is high, color animal migration is small.
Description
Technical field
The invention belongs to polyurethane suede-like artificial leather preparation method technical field, and in particular to a kind of acid amides for being easy to dye
The manufacture method of based polyurethanes suede-like artificial leather.
Background technology
Surface has the artificial leather of dyestuff coloring effect, and its bright in luster, transparency is high, is applied to the fashion such as case and bag women's shoes
It is loved by people on product, but conventional synthesis leather generally uses pigment coloring mode, it is impossible to and reaching dyestuff coloring is had
Effect, although dyestuff coloring effect can be obtained using the manufacture method that the coloring of dyestuff water colouring agent is added in coating material,
But this manufacture method can bring serious colour migration to move, poor color fastness, the problems such as cost price is high, making for product is constrained
With.
In traditional synthetic leather manufacturing process, mill base, toner and organic dyestuff, metal network need to be added in coating paste
The coloring materials such as dyestuff are closed, so that assign finished leather different colors, but coat colorization feel is partially hard, and coloring formula is once
It is determined that after, coating is presented solid color, and gloss and color and luster are dull, without the stereovision such as the depth, light and shade, new and old.Exploitation is just
In dyeing artificial leather be those skilled in the art need thinking problem.
The content of the invention
The technical problems to be solved by the invention are directed to above-mentioned prior art and provide a kind of polyurethane suede be easy to and dye
Dough figurine fabricate-leather, can be dyeed with dyestuff, and product has the characteristics of bright-colored, coating permeability is good, surface color fastness is high.
The present invention the used technical scheme that solves the above problems is：A kind of acid amides based polyurethanes matte people for being easy to dye
Fabricate-leather manufacture method, is to use Amide based solvents type polyurethane resin to configure to cover with paint, lacquer, colour wash, etc. slurry, then will cover with paint, lacquer, colour wash, etc. slurry and covers with paint, lacquer, colour wash, etc. in suede
Dough figurine fabricate-leather scrim surfaces, then the polyurethane suede-like artificial leather dyeed by dyeing treatment；
Covering with paint, lacquer, colour wash, etc. slurry includes the component of following mass parts：
100 parts of Amide based solvents type polyurethane resin
20~120 parts of dimethylformamide
20~120 parts of acetone.
Preferably, described covering with paint is to make surface technology by release liners dry method to fit to Amide based solvents type polyurethane surface layer
In artificial leather wet half-finished product.
Preferably described covering with paint is that Amide based solvents type polyurethane is covered with paint, lacquer, colour wash, etc. into slurry with surface printing method to cover with paint, lacquer, colour wash, etc. in artificial leather
Dry method surface of semi-finished.
Preferably, the covering with paint is that Amide based solvents type polyurethane is applied into finish coat with rolling method to be coated with to artificial leather base fabric
Surface of semi-finished.
Described dyeing
Polyurethane resin artificial leather in the present invention is easy to dyeing, and dyeing processing mode includes pad dyeing, dye gigging, overflow dyeing or gas
Stream dyeing.
Compared with prior art, the advantage of the invention is that：Using Amide based solvents type polyurethane resin as matte people
Fabricate-leather top finishing material, can carry out dyeing process with dyestuff, the color effect by that can obtain dyestuff coloring after dyeing treatment
Really, making product has the characteristics of bright-colored, coating permeability is good, surface color fastness is high, color animal migration is small, with common matte people
Fabricate-leather dyeing is few compared to dyestuff usage amount, and dyeing time is very short, and dyeing can be completed compared with low temperature, and dyeing is simpler
Single, cost is relatively low, energy saving.
