Preferably, the strippable grain layer 1 is release paper.
Preferably, the leather support layer 2 is made of polyurethane with colors.
Preferably, the first pattern protective layer 3 is made of polyurethane with colors.
Preferably, the print pattern layer 4 is printed with ink.
Preferably, the second pattern protective layer 5 is made of polyurethane with colors.
Preferably, the adhesive layer 6 is made of liquid glue; preferably, the liquid size is a polyurethane.
Preferably, the base layer 7 is cloth or PET plastic.
Preferably, the color of the print pattern layer 4 is different from the colors of the leather support layer 2, the first pattern protection layer 3, and the second pattern protection layer 5.
Specifically, the peelable grain layer 1 is release paper, and first grains are formed on the lower surface of the peelable grain layer, and the form mode can adopt the existing mode, which is not described again; the first grains are formed on the lower surface of the strippable grain layer 1 firstly, so that the second grains matched with the upper surface of the leather supporting layer 2 are formed. After the first texture is formed on the lower surface of the peelable texture layer 1, polyurethane with color is coated on the lower surface of the peelable texture layer 1 in the conventional coating mode, which is not described herein again; after the polyurethane coated on the lower surface of the strippable grain layer 1 is naturally cured, a colored and transparent leather supporting layer 2 can be formed; at this moment, just formed the second line that agrees with first line at the upper surface of leather supporting layer 2, with strippable line layer 1, also be exactly from the back that leather supporting layer 2 was peeled off from the type paper, the second line of leather supporting layer 2 just uses the superiors of synthetic leather as the human body, has increased sense of touch and the third dimension on synthetic leather surface. The peeling operation of the peelable grain layer 1 in this embodiment is performed after the artificial leather is completely manufactured.
After the leather support layer 2 is formed, polyurethane with colors is coated on the lower surface of the leather support layer 2, the coating mode can be the existing one and is not described again; when the polyurethane coated on the lower surface of the leather support layer 2 is naturally cured, the first pattern protection layer 3 having a color and transparency can be formed. The flatness of the lower surface of the first pattern protection layer 3 needs to be ensured during the formation of the first pattern protection layer 3, so as to ensure the forming quality of the subsequent printed pattern layer 4 on the first pattern protection layer 3. In a specific application, the flatness of the lower surface of the first pattern protection layer 3 can be ensured by means of multiple screeding.
After the first pattern protection layer 3 is formed, the printing ink is printed on the flat lower surface of the first pattern protection layer 3 in a preset pattern decoration mode through a digital printer, and the pattern printing layer 4 can be formed after natural drying. It should be noted that, in this embodiment, the pattern is not directly printed on the lower surface of the leather supporting layer 2 after being leveled, so as to avoid the leveling action on the lower surface of the leather supporting layer 2 from affecting the quality of the second texture forming on the upper surface of the leather supporting layer 2. Moreover, the thickness of the leather support layer 2 and the first pattern protection layer 3 is inevitably larger than that of the leather support layer 2, so that the effect of printing patterns on a thicker base material is better.
After the pattern-printing layer 4 is formed, polyurethane with colors is coated on the lower surface of the pattern-printing layer 4 in the conventional manner, which will not be described herein; when the polyurethane coated on the lower surface of the pattern printed layer 4 is naturally cured, the second pattern protection layer 5 having a color and transparency can be formed. So just formed the sandwich structure of first pattern protective layer 3 and second pattern protective layer 5 on pattern printing layer 4 upper and lower two sides, can not touch pattern printing layer 4 during the use, and when external force acted on the synthetic leather from different sides, also can act on first pattern protective layer 3 or second pattern protective layer 5 earlier, can not direct action in pattern printing layer 4 to pattern buffering protection has been formed. The pattern printing layer 4 is ensured not to be essentially invalid or deformed after being used for a long time, thereby ensuring the quality of artificial leather pattern decoration for a long time.
It should be noted that the color of the ink used for printing the pattern printing layer 4 is different from the colors of the polyurethane of the leather support layer 2, the first pattern protection layer 3 and the second pattern protection layer 5, and has a distinct color difference, so that the color of the pattern printing layer 4 can be clearly compared with the colors of the leather support layer 2, the first pattern protection layer 3 and the second pattern protection layer 5. The decorative pattern can be highlighted under the condition of external illumination, so that the visual impact is enhanced, the light aesthetic feeling of the pattern is increased, and a user can feel more pleasurable and can feel comfortable. Preferably, the ink used for printing the pattern printing layer 4 can also be fluorescent ink, so as to further highlight the decorative pattern, and the decorative pattern presented by the fluorescent ink is safe and stable under the protection of the interlayer of the first pattern protection layer 3 and the second pattern protection layer 5.
After the second pattern protection layer 5 is formed, the liquid glue is polyurethane and is coated on the lower surface of the leather support layer 2 to serve as the glue, the coating mode can be the existing one, and details are not repeated here; after the coating is finished, the base layer 7 is covered on the sizing material, and then the baking and heating are carried out, so that the sizing material is solidified and bonded to form the bonding layer 6, and meanwhile, the digital printing light-transmitting artificial leather is also prepared. The base layer 7 in this embodiment may be a chemical microfiber, cotton, hemp, or other cloth. It is worth to be noted that the glue is separated from the pattern printing layer 4 by the second pattern protection component 5, and the influence on the quality of the decorative pattern of the pattern printing layer 4 when the glue is cured and bonded by baking and heating is also avoided.
In conclusion, the texture is formed on the upper surface of the leather supporting layer, so that the touch feeling and the stereoscopic impression of the surface of the artificial leather are increased; meanwhile, the printed pattern layer is positioned in the interlayer separating protection between the flat lower surface of the first pattern protection layer and the second pattern protection layer, so that the patterns on the printed pattern layer can not deform while the breakage and the essential failure of the patterns caused by using friction are avoided, and the quality of artificial leather pattern decoration is ensured for a long time; in addition, the colour of printing the pattern layer forms obvious colour difference contrast with the colour of leather supporting layer, first pattern protective layer and second pattern protective layer, when light from synthetic leather finished product bottom direct irradiation, can print the pattern of layer salient in the synthetic leather with hiding to present the surface at the synthetic leather with decorative pattern, make the surface of synthetic leather bright and beautiful colorful, let the user more pleasing to the eye, the body and mind of releiving.
