DESCRIPTION
COLOR AND PATTERN PRINTING TECHNIQUE APPLIED BETWEEN COATING LAYERS FORMING ARTIFICIAL LEATHER
FIELD OF INVENTION
This invention is related to a process and a product manufactured through such process that is firstly used in this sector in the world integrating coating and pattern rotation and paper transfer printing and being different from the artificial leather used in furniture, shoemaking, garment and accessories sectors. The printing technique applied between the coating layers forming the artificial leather in the method developed by this invention ensures the manufacturing of the product with a natural leather appearance, higher color friction and color light fastness by means of an printing technique.
PRIOR ART
In the prior art, patterned artificial leather is manufactured by transferring different colors and patterns on the surface of the artificial leather by means of pattern cylinders or paper transfer printing technique. It is difficult to obtain both high color friction fastness and unavoidable to have changes in the original appearance and permanence of the paper pattern in the productions according to the known technique.
MANUFACTURING OF ARTIFICIAL LEEATHER COATED WITH POLYU REETH AN - POLYVYNYLCHLORIDE
In the known technique of artificial leather production, carrier paper (patterned) in the coating machine is provided with the requested thickness and weight and dried by being coated by polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals by the first blade. The chemical carrier paper being dried reaches at the second blade and its chemical is transferred to the carrier paper similarly by means of coating polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals at requested thickness and weight. Similar to the former application, the chemical carrier paper being dried reaches at the third blade and its chemical is transferred to the carrier paper similarly by means of coating PU and/or PVC, solvent and other auxiliary chemicals at requested thickness and weight. Finally, bottom surface is glued onto paper with chemical, and dried. The product is obtained by the separation of the carrier paper from its bottom surface in its outlet from the machine.
PRINTING PROCESS ACCORDING TO THE PRIOR ART
Artificial leather processed in coating machine reaches at the printing machine, and here desired pattern is applied on the surface of the artificial leather. The printing solution consisting of dye, solvent and other auxiliary chemicals is applied on the surface of artificial leather by patterned rotation printing method, then dried and wrapped. Additionally, the colored pattern on paper is transferred on artificial leather by using pattern paper in the paper transfer machine. However, color abrasion fastness and light fastness of colored printing applied on the surface of artificial leather is very low in comparison to the data of the process developed by this invention.

DESCRIPTION OF INVENTION
The process relating to the colored and patterned printing technique applied between coating layers forming artificial leather developed by this invention and patterned flexo printing, printed printing and transfer paper printing on the product manufactured according to the said process are realized in two phases. In this process, pattern-printing by flexo printing, printing or transfer paper printing system is not applied on the surface of artificial leather.
Phase 1 - Artificial leather is manufactured by applying pattern flexo printing, printing (emprime) or transfer paper printing on the back surface of one or more layers forming the surface of artificial leather and then giving other layers continuously or discontinuously.
Phase 2 - Following the application of pattern flexo printing, printing (emprime) or transfer paper printing on surface of semi-finished artificial leather having been coated or on the surface of coagulated surface to be coated, artificial leather is manufactured by carrying out transparent (without dye) or transparent with dye coating process. Thus, rich color/pattern appearance is achieved with high color, friction and light fastness without changing the original look of the carrier paper.
Alternative processes where the product developed by this invention has natural leather appearance and rich color / pattern appearance with high color friction and light fastness are comprised as follows:
The alternative processes of the Phase 1 are mentioned below:
1.1 - 1 or 2 Blade Transparent Coating + Pattern Flexo or Emprime Printing + 1 or 2 Blade Coating Process (Continuous) on an Artificial Leather Guiding Paper
• 1.2 - 1 or 2 Blade Transparent Coating + Transfer Paper Printing + 1 or 2 Blade
Coating Process (Continuous) on an Artificial Leather Guiding Paper
• 1.3 - 1 or 2 Blade Transparent Coating + Pattern Flexo or Emprime + 1 or 2 Blade
Coating Process (Discontinuous) on an Artificial Leather Guiding Paper
• 1.4 - 1 or 2 Blade Transparent Coating + Transfer Paper Printing + 1 or 2 Blade
Coating Process (Discontinuous) on an Artificial Leather Guiding Paper
The alternative processes of the phase 2 are as follows:
2.1 - Pattern Flexo or Emprime Printing + Transparent Coating Process on a
Coagulated Surface to be coated.
2.2 - Transfer Paper Printing + Transparent Coating Process on a Coagulated Surface to be coated.
2.3 - Pattern Flexo or Emprime Printing + Transparent Coating Process on semifinished artificial leather having final layers coated.
2.4 - Transfer Paper Printing + Transparent Coating Process on semi-finished artificial leather having final layers coated. 1.1 - 1 OR 2 BLADE TRANSPARENT COATING + PATTERN FLEXO OR EMPRIME PRINTING + 1 OR 2 BLADE COATING PROCESS (CONTINUOUS) ON AN ARTIFICIAL LEATHER GUIDING PAPER
Alternative application 1.1 is shown in Figure - 4. In the known technique of artificial leather manufacturing, the carrier paper (24) (with effect of natural leather surface) is provided with the requested thickness and weight in the coating machine and then dried after being coated by 1 or 2 blade (26 then 28) with PU and/or PVC, solvent and other auxiliary material. The carrier paper bearing chemicals received from the drying process in the oven (27 and then 29) reaches at the artificial leather line different from the known method and at the synchronized and/or non-synchronized flexo printing or emprime machine (30).
At this step, patterned rotation printing method is implemented by means of the printing solution comprised by dye, solvent and other auxiliary chemicals; dried in the internal oven in the printing machine; and transferred over the film on the carrier paper. Following this process, the obtained patterned printed carrier paper with chemicals reaches at the coating blade (31) and is transferred over the carrier paper dried at the requested thickness and weight by being coated with PU and/or PVC, solvent and other auxiliary chemicals. Similarly, the carrier paper bearing chemicals and processed in drying unit (32) reaches at the final coating blade (33) and is transferred over the carrier paper being formerly dried by means of PU and/or PVC, solvent and other auxiliary chemicals with the requested thickness and weight. Finally, the paper with the chemicals is attached with a suitable surface (cloth, non-woven, etc.) complying with the requested features and dried in the furnace (35); and the product is obtained by separating the chemical ground (38) from the carrier paper (37) in the outlet of the machine.

Alternative application 1.2 is shown in Figure - 5. In the known technique of artificial leather manufacturing, the carrier paper (24) (with effect of natural leather surface) is provided with the requested thickness and weight in the coating machine and then dried after being coated by 1 or 2 blade (26 then 28) with PU and/or PVC, solvent and other auxiliary material. The carrier paper bearing chemicals received from the drying process in the oven (27 and then 29) reaches at the transfer paper printing machine (45) different from the known method. At this step, the requested pattern and color on the transfer paper are transferred over the film on the carrier paper. Following this process, the obtained patterned printed carrier paper with chemicals reaches at the following coating blade (48) continuously and is transferred over the carrier paper dried at the requested thickness and weight by being coated with PU and/or PVC, solvent and other auxiliary chemicals. Similarly, the carrier paper bearing chemicals and dried in the furnace (49) reaches at the final coating blade and is transferred over the carrier paper being formerly dried by means of PU and/or PVC, solvent and other auxilliary chemicals with the requested thickness and weight. Finally, the paper with the chemicals is attached with a suitable surface (51) complying with the requested features and dried in the furnace (52); and the product is obtained by separating the chemical ground - printed atificial leather (55) from the carrier paper (54) in the outlet of the machine.

In the known technique of artificial leather manufacturing, the carrier paper (with effect of natural leather surface) is provided with the requested thickness and weight in the coating machine and then dried after being coated by 1 or 2 blade with PU and/or PVC, solvent and other auxiliary material. The carrier paper bearing chemicals received from the drying process reaches at the synchronized and/or non-synchronized flexo printing or emprime machine (62), being different from the known technique. At this step, patterned rotation printing method is implemented by means of the printing solution comprised by dye, solvent and other auxiliary chemicals; dried; and transferred over the film on the carrier paper. Thus, patterned carrier paper (63) with a printed film is obtained.
Following this process, the obtained film printed carrier patterned paper (64) is again attached to the coating machine. Coating blade (66) again transfers over the carrier paper having been dried in the furnace (67) initially being coated with chemicals by being coated by PU and/or PVC, solvent and other auxiliary chemicals at the requested thickness and weight. Similarly, the carrier paper bearing chemicals and processed in the furnace (67) reaches at the following coating blade (68) and is transferred over the carrier paper being formerly dried by means of PU and/or PVC, solvent and other auxiliary chemicals with the requested thickness and weight. Finally, the paper with the chemicals is attached with a suitable surface (cloth, non-woven, etc.) complying with the requested features and dried in the furnace (70); and the product is obtained by separating the chemical ground (73) from the carrier paper (72) in the outlet of the machine.

Similarly, the carrier paper with chemicals having been dried (102) reaches at the third blade (103) and PU and/or PVC, solvent and other auxiliary chemicals are transferred either with transparent (without dye) or transparent dye to carrier paper bearing chemical at the requested thickness and weight. Finally, pattern printed coagulated surface (96) formerly obtained through either flexo or emprime printing system (95) is glued (104) to the paper with chemical and dried (105). The product is obtained by the separation of the surface (108) from the carrier paper (107).
The product obtained by being coated with 3 blades (99, 101 and 103) indicated in the Figure 11 may also be manufactured by means of 2 blade coating and/or 1 blade coating method.
2.2 TRANSFER PAPER PRINTING + TRANSPARENT COATING PROCESS ON A COAGULATED SURFACE TO BE COATED

Finally, pattern printed coagulated surface (111) formerly obtained through transfer paper printing system (110) is glued (119) to the paper with chemical and dried (120). The product is obtained by the separation of the surface (123) from the carrier paper (122).
The coating blades (114, 116 and 118) used in the process indicated in the Figure 13 may also be used either with 1 blade and/or 2 blades.
2.3 PATTERN FLEXO OR EMPRIME PRINTING + TRANSPARENT COATING PROCESS ON SEMI-FINISHED ARTIFICIAL LEATHER (PU/PVC) WITH LAST LAYERS COATED
Alternative application 2.3 is shown in Figure - 14, Figure 15 and 16. Semi-finished artificial leather (PU-PVC) is manufactured differently from the known technique, by means of pattern printing through flexo or emprime printing systems (Figure 15) and put into coating process again (Figure 16), thereby preserving the original look of the pattern paper and ensuring a rich color/pattern appearance with high color fastness.
In the known technique of artificial leather manufacturing, the carrier paper (with effect of natural leather surface) (124) is coated by the first blade (126) with polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals at the requested thickness and weight in the coating machine and then dried. The carrier paper with chemicals having been dried (127) reaches at the second blade (128); and polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals are transferred to carrier paper bearing chemical at the requested thickness and weight. Similarly, the carrier paper with chemicals having been dried (129) reaches at the third blade (130) and PU and/or PVC, solvent and other auxiliary chemicals are transferred to the carrier paper bearing chemical at the requested thickness and weight. Finally, surface (cloth, non-woven, etc) (131) is glued (131) to the paper with chemical and dried (132). Semi-finished artificial leather (PU-PVC) (136) is obtained to be used in the following phases by the separation of the chemical surface (135) from the carrier paper (134) at the exit of the machine. In this phase of production, number of coating blades (126, 128 and 130) may be increased or decreased according to the requested semi-finished artificial leather (136).
The produced semi-finished artificial leather obtained (PU-PVC) (136) reaches at Flexo or printing machine (137). At this step, requested pattern and color are transferred over the artificial leather surface and it is dried and wrapped. Thus, semi-finished artificial leather (138) having pattern printed is produced by means of this process.
In the known technique of artificial leather manufacturing, the carrier paper (with effect of natural leather surface) (139) is coated by the first blade (141) with polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals with transparent (without dye) or transparent dye at the requested thickness and weight in the coating machine and then dried (142). The carrier paper with chemicals having been dried (142) reaches at the second blade (143); and polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals are transferred to carrier paper bearing chemical with transparent (without dye) or transparent dye at the requested thickness and weight. Similarly, the carrier paper with chemicals having been dried (144) reaches at the third blade (145) and PU and/or PVC, solvent and other auxiliary chemicals with transparent (without dye) or transparent dye are transferred to the carrier paper bearing chemical at the requested thickness and weight. Finally, semi-finished artificial leather having formerly pattern printed by means of flexo or emprime printing system (Figure - 15) is glued (146) as surface and dried (147). Semi-finished artificial leather (PU-PVC) (136) is obtained by the separation of semi-finished artificial leather with coated with pattern printing (150) from the carrier paper (149) at the exit of the machine. The transparent coating process by 3 blades (141, 143 and 145) used in the process shown in the Figure - 16 may also be performed by 1 or 2 blades.
2.4 PATTERN FLEXO OR EMPRIME PRINTING + TRANSPARENT COATING PROCESS ON SEMI-FINISHED ARTIFICIAL LEATHER (PU/PVC) WITH LAST LAYERS COATED
Alternative application 2.4 is shown in Figure - 17, Figure 18 and 19. Semi-finished artificial leather (PU-PVC) is manufactured differently from the known technique, by means of pattern printing through transfer paper printing system and put into coating process again thereby preserving the original look of the pattern paper and ensuring a rich color/pattern appearance with high color fastness.
In the known technique of artificial leather manufacturing, the carrier paper (with effect of natural leather surface) (151) is coated by the first blade (153) with polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals at the requested thickness and weight in the coating machine and then dried. The carrier paper with chemicals having been dried (154) reaches at the second blade (155); and polyurethane and/or polyvinyl chloride, solvent and other auxiliary chemicals are transferred to carrier paper bearing chemical at the requested thickness and weight. Similarly, the carrier paper with chemicals having been dried (156) reaches at the third blade (157) and PU and/or PVC, solvent and other auxiliary chemicals are transferred to the carrier paper bearing chemical at the requested thickness and weight. Finally, surface (cloth, non-woven, etc) is glued (158) to the paper with chemical and dried (159). Semi-finished artificial leather (PU-PVC) is obtained to be used in the following phases by the separation of chemical surface (162) from the carrier paper (161) at the exit of the machine. In this phase of production, number of coating blades (153, 155 and 157) may be increased or decreased according to the requested semi-finished artificial leather (162).
The produced semi-finished artificial leather obtained (PU-PVC) (163) reaches at transfer paper printing machine (164). At this step, requested pattern and color are transferred over the artificial leather surface and it is dried and wrapped. Thus, semi-finished artificial leather (165) having pattern printed is produced by means of this process.
