Abstract
The present invention relates to a dyeing and printing process and device for leather. Transfer printing paper is attached to leather, the transfer printing for the leather and analogues is accomplished within 0.5 to 3 seconds under the conditions of the temperature of 120 DEG C to 220 DEG C and the pressure of 15Kg to 70Kg, and then a layer of protecting agent is coated. The present invention has the characteristics of vivid flower color, simple process and low cost and provides a new way for printing and dyeing the leather, and the international patent classification number of the patent is D06P3/32.
Description
The invention relates to the dyeing of leather, printing method and relevant devices, more particularly about the method for transfer printing and the equipment of leather, international Patent classificating number is D06P3/32.
Leather is a kind of traditional product, one to being used for hatting, clothes, handbag and leather trunk etc., but this series products is monochromatic always, not that black is exactly brown or white, 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 for they.In China, leather pattern-printing is one all the time and treats the big problem with research, a kind of printed leather and manufacture method in Chinese patent application CN-85104486, have been introduced, it uses traditional printing machine, the slurry of stamp is the mixture of a kind of coating, crosslinking agent and adhesive, by printing machine suede and surface leather are carried out stamp, dry again after printing off pattern, bake and obtain printed leather thus, the shortcoming of this technology is that technology is cumbersome, step is too many, and the pattern that obtains is limited, and color is not gorgeous.
Abroad, the development of printed leather also is very slowly, 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, the decorative pattern that prints off is quite dim, the flower type is also more coarse, even can not print off light decorative pattern on dark background color leather.
One of purpose of the present invention provides a kind of improved leather coloring, printing technology and equipment, 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 of seal expand the surface to and bright and clean surface leather and artificial leather simultaneously from suede.
Two of purpose of the present invention provides a kind of simple leather coloring, and printing method overcomes too many, the not gorgeous defective of color of step that prior art exists.
Three of purpose of the present invention provides a kind of printing equipment, and it is simple in structure, is applicable to the transfering printing process of leather.
Purpose of the present invention and task realize by following technological means.
At first, the leather that will use for the present invention, comprise Animal Skin such as pig, sheep, ox, horse skin with the conventional industry general technology preliminary treatment and dyeing, look later institute's stamp look difference, color can be arbitrarily, comprises black, red, yellow, grey, white etc.Dry stand-by then.
The due south of commercially available transfer printing paper is proper with the front configuration of the leather of handling, be 120-220 ℃ in temperature, pressure is 15-70Kg/cm
2, the time is under 0.5-3 condition second, and being preferably temperature is 140-200 ℃, and pressure is 15-60Kg/cm
2, the time is 1-3 second, and best is that temperature is 150-160 ℃, and pressure is 25-50Kg/cm
2, the time is to come leather is implemented transfer printing by printing machine under the 1-1.5 condition of second.
Can be coated with the last layer protective agent on the leather that has printed flower, can be polyurethane at this protective agent, acrylate or formaldehyde fixed agent, and use amount is 2-15wt%, is preferably 4-10wt%, bake out temperature is 90-110 ℃.
Transfer printing paper of the present invention can be buied from the market, and dispersed sublimation dye is arranged on it, and at high temperature it distillation transferance takes place directly to leather.Because the disperse dyes chromatogram is more complete, so the kind of transfer printing paper is also a lot, the pattern after having printed is also bright-coloured, and is various.
Protective agent of the present invention can also be buied from market, because they all are that industry technical staff is known, in this few introduction.
Figure (1) is the sketch of printing machine of the present invention, and here, symbol 1-5 represents driving wheel, follower, driving wheel, rubber layer and nervous screw spring etc. respectively.
Printing equipment of the present invention and the present general basic class of printing machine Seemingly, but done some improvement at key structure, particularly, it comprises driving wheel (1) and follower (2), driving wheel (1) is connected by belt or gear drive by driving wheel (3), is coating the thick rubber layer of one deck 2-30mm (4) on the surface of driving wheel. Driving wheel drives driving wheel, and leather and transfer printing paper close to paste and passes through from the seam of driving wheel and follower, finish the transfer printing operation under the effect of heat and pressure.
Control the pressure of follower by nervous screw spring (5), in follower hollow heating wire is housed, the mode heat temperature raising with electricity makes it prescribed limit according to the invention. Its mode of communicating, internal structure is identical with the common electrical hot-rolling.
Printed leather of the present invention is compared with present similar products at home and abroad has following advantage (1), and its decorative pattern lines are meticulous, and pattern contour is clear, and chromatogram is complete, and pattern is bright bright-coloured. (2) not only can be dark at shallow background color leather seal, can also be at dark background color seal light color, the kind of (3) printed leather has expanded on surperficial leather and the artificial leather from single matte seal. (4) technology is simple, and is easy to operate, and step is few, cost is low.
Further specify the present invention by the following examples, but embodiment only is used for explanation, can not place restrictions on the present invention, those skilled in the art can be made many variations in view of the above, but all should understand within the scope of the invention.
Example one:
A pigskin that has dyed grey background color being pasted mutually with a transfer printing paper front put on the transfer printing machine, is 150-160 ℃ in temperature, and pressure is 20-50Kg/cm
2Condition under, finish transfer printing in 1-1.5 in second, on leather, apply one deck formaldehyde protective agent with common coating machine more afterwards, be to dry under the 90-110 ℃ of situation to get product in temperature, this leather can be done suitcase, chest, leather shoes etc.
With a sheepskin that has dyed white, paste mutually with the transfer printing paper front of the few size of an area difference and to put into transfer printing machine, in temperature was 161-210 ℃ of scope, pressure was 60Kg/cm
2Condition under, leather is carried out transfer printing, apply one deck protective agent afterwards again, the oven dry get final product product.
