Problems solved by technology

[0003] see Image 6 , the three straight lines in the figure are the graphics printed on the non-woven fabric. When the non-woven fabric is pressed, the relationship between the pressed place and the printed image is random, and there are many situations. Partially coincide with the pattern, the heat-pressed part does not coincide with the pattern at all, and the heat-pressed part completely coincides with the pattern. In each case, the clarity of the pattern is different, which affects the appearance and reduces the composite fastness of the non-woven fabric.
[0004] In the prior art, in order to solve this defect, a method similar to the bronzing process is adopted to transfer the substrate with a film layer, a release layer, an ink layer, and an adhesive layer to the surface of the non-woven fabric by hot pressing, and make it compatible with the printing Composite substrate layer, high cost, relatively expensive material, single color, and its ink must be located on the surface of the lamination, easy to fade, etc.

Embodiment 1

[0031] see figure 1 , a composite non-woven fabric, including a non-woven surface layer 10 and a printing substrate layer 20, the top surface of the printing substrate layer 20 is printed with several ink areas 30, and the several ink areas 30 are distributed at intervals. The non-woven surface layer 10 is compounded on the top surface of the printing substrate layer 20 and forms a pressing area 40 therewith, and the pressing area 40 overlaps with the ink area 30 . In this way, the pattern display of the ink area 30 is consistent with the effect after hot pressing, so as to avoid that some parts of the printed pattern are hot pressed, and some places are not hot pressed, resulting in inconsistent colors and effects.

[0032] In this embodiment, the printing substrate layer is a calendering-treated printing substrate layer. The non-woven surface layer 10 is bonded to the top surface of the printing substrate layer 20 by thermocompression or ultrasonic bonding. The printing s...

Embodiment 2

[0039] see image 3 , a composite non-woven fabric, comprising a non-woven fabric surface layer 10 and a printing substrate layer 20, the top surface of the printing substrate layer 20 is printed with several ink areas 30, and the several ink areas 30 are distributed at intervals; the non-woven fabric surface The layer 10 is thermally pressed on the top surface of the printing substrate layer 20 to form a pressing area 40 thereon, and the pressing area 40 and the ink area 30 do not overlap with each other. The ink layer with the printed pattern is staggered from the pressing area 40, so that the display effect of the ink layer is not affected by the pressing, avoiding that some places of the printed pattern are hot-pressed, and some places are not hot-pressed, resulting in color, The effect is inconsistent.

[0040] In this embodiment, the printing substrate layer is a calendering-treated printing substrate layer. The non-woven surface layer 10 is bonded to the top surface o...

Embodiment 3

[0046] see Figure 4 , a composite non-woven fabric and its printing and lamination method, its main structure and method are the same as those in Embodiment 1, the difference is that an air cushion area 50 with a cavity can also be formed between two adjacent lamination areas 40 .

Abstract

The invention relates to a composite non-woven fabric and a printing pressing method thereof, wherein the composite non-woven fabric comprises a non-woven fabric surface layer and a printing substratelayer, a plurality of ink regions are printed on the top surface of the printing substrate layer, and are arranged at intervals, the non-woven fabric surface layer is compounded on the top surface ofthe printing substrate layer, and forms pressing regions with the top surface of the printing substrate layer, and the pressing regions and the ink regions are overlapped each other. According to thepresent invention, the composite non-woven fabric can ensure the clarity uniformity of the patterns in the ink regions, is beautiful, and has the improved compounding fastness.

Description

technical field [0001] The invention relates to the field of non-woven fabric processing, in particular to a composite non-woven fabric and a printing and pressing method thereof. Background technique [0002] At present, non-woven fabrics and similar materials will change their transparency and texture appearance after being heat-pressed. Therefore, if there is printing and embossing on the product, the printing effect will appear different on the part subjected to heat pressing and the part not subjected to heat pressing. This will reduce the aesthetic feeling and even produce the defect of unclear printing. [0003] see Image 6 , the three straight lines in the figure are the graphics printed on the non-woven fabric. When the non-woven fabric is pressed, the relationship between the pressed place and the printed image is random, and there are many situations. Partially overlap with the pattern, the heat-pressed place does not coincide with the pattern at all, and the h...
