Abstract
The present invention relates to a kind of printed leather and leather pattern-printing method that is printed on decorative pattern and pattern on its surface.Slurry as stamp is a kind of mixture of being made up of whiting (or being mixed with look coating) cross linking agent and adhesive, on roller printing machine, suede and surface leather are carried out stamp with this coating compound by printing roller, dry again after printing off decorative pattern and pattern, bake again at last.Printed leather lines of the present invention are meticulous, and pattern contour is clear, and fancy is bright bright-coloured.
Description
The present invention relates to a kind of leather, particularly a kind of printed leather that is printed on decorative pattern and pattern on its surface.The invention still further relates to a kind of printing method, particularly a kind ofly print off decorative pattern and method of patterning at leather surface.
Leather is a kind of traditional product, and one to being used to make shoes and hats, clothes, handbag and leather trunk etc.But this series products is monochromatic always, is not that black is exactly brown or white, and they are only by forming behind the dyeing.Traditional leather products is because its dull coloring is difficult to the enjoyment to a kind of U.S. of people except practicality.In China, leather pattern-printing is a gap all the time, as far back as the fifties, domesticly just begins to develop the leather pattern-printing technology, but because subject matters such as printing coating and process conditions are unresolved, fails to succeed always.Abroad also simultaneously in exploitation leather pattern-printing technology, as the sample of a printed leather is provided on the leather technology exchanging meeting that in October, 1984, Mitsubishi group held in China Tianjin.But these external printed leathers only belong to matte stamp leather, and the decorative pattern that prints off is quite dim, and the flower type is also more coarse, even can't print off light decorative pattern on dark background color leather.Its reason is to fail to use a kind of suitable printing technology.Employed in addition printing equipment and later process also exist some an open questions as oven dry and baking etc.
The objective of the invention is to provide a kind of improved printed leather, make the pattern of printed leather bright-coloured, the flower type is meticulous, not only to obtain the dark decorative pattern on the shallow background color leather, also on dark background color leather, print off light decorative pattern, make the leather that is printed expand the brighter and cleaner surface leather in surface to simultaneously from suede.
Purpose of the present invention also will provide a kind of desirable leather pattern-printing method, makes the printed leather that obtains by this method satisfy above-mentioned requirements.
The present invention constitutes like this, this is a kind of printed leather that is printed on decorative pattern and pattern on its surface, the coating compound that different with prior art is decorative pattern all on the leather surface and pattern is made up of whiting (or being mixed with look coating), cross linking agent and adhesive can also have the coating of one deck polyurethane or acrylate on the surface of this printed leather.
The invention still further relates to and a kind ofly print off decorative pattern and method of patterning at leather surface, this method is: adopt a kind of coating compound of being made up of whiting (or being mixed with look coating), cross linking agent and adhesive by printing roller suede and surface leather to be carried out stamp on roller printing machine, in cylinder drying machine, dry again after printing off decorative pattern and pattern, in baker, finish the coating and the oven dry once more that bake or be coated with again last layer polyurethane or acrylate then.
Printed leather of the present invention is compared with existing external like product and is had the following advantages, and (1) its decorative pattern lines are meticulous, and pattern contour is clear, and pattern is bright bright-coloured.(2) dark decorative pattern on the shallow background color leather not only can be arranged, the light decorative pattern on the dark background color leather also can be arranged.(3) kind of printed leather has also expanded surperficial stamp leather to from single matte stamp leather.(4) its physical quality such as tensile strength and tear-resistant intensity also increase than existing product, generally are respectively 16.5N/mm
2And 35N/mm
2About, improve 3N/mm than existing product respectively
2And 7N/mm
2About.
Leather pattern-printing method of the present invention is implemented easily, and simple to operate, it can make the leather that prints off reach above-mentioned good effect, and can put into production rapidly.
Come printed leather of the present invention and manufacture method thereof are described in further detail below in conjunction with embodiment.
This is a kind of printed leather that is printed on decorative pattern and pattern on its surface, and said leather promptly can be a suede, also can be the surface leather of any surface finish.Coating as stamp is a kind of coating compound of being made up of whiting (or being mixed with look coating), cross linking agent and adhesive.Adding whiting is the vividness of printing off decorative pattern in order to improve, and whiting is many more, and then vividness is good more, and pattern is also bright more, but whiting is also too much unsuitable, must be an amount of.Here said whiting is a titanium dioxide, and fluorescent coating or pigment that said look coating is organic or inorganic, said cross linking agent are hydroxymethyl-2 dihydroxy-ethylene urea, and said adhesive is a polyacrylonitrile.In each kilogram coating compound, whiting contains 20%～25%(weight), cross linking agent contains 4%～8%(weight), adhesive contains 67%～76%(weight).When being mixed with look coating in the coating compound, whiting contains 20%～25%(weight), look coating contains 10%～25%(weight), cross linking agent contains 4%～8%(weight), adhesive contains 42%～66%(weight).The surface of printed leather of the present invention also scribbles one deck polyurethane or acrylate, and purpose is in order further to increase the surperficial smooth degree of stamp leather etc.
Leather pattern-printing method of the present invention realizes by printing machine, the concavo-convex degree of depth of the decorative pattern of printing roller is elected 9～10 as, and the degree of depth should not be too dark, also should not be too shallow, too dark can causing under the coating dragged phenomenon, and the too shallow pattern blurring that then can not print or print off is unclear.
Promptly change in the cylinder drying machine after printed and dry, bake out temperature is controlled at 90 ℃～110 ℃, and drying time is 1～3 minute.And then change in the baker and bake.Baking temperature is controlled at 140 ℃～160 ℃, and the time of baking is 2～3 minutes.In the process of baking, the interlinkage reaction will take place in cross linking agent and adhesive contained in the coating, will be more firm by this reaction cross linking agent and adhesive in conjunction with getting, thus make the wear-resisting rubbing fastness of stamp leather decorative pattern obtain further to improve.
At last, also can be coated with last layer polyurethane or acrylate more later on finishing above-mentioned stamp and oven dry and roasting process, and dry in cylinder drying machine again, bake out temperature still is 90 ℃～110 ℃, and drying time also is 1～3 minute.
