Description

Technical Field

[0001] This utility model relates to the field of clothing technology, specifically to a graphic printing tool for denim fabric. Background Technology

[0002] In terms of denim apparel pattern design, due to the manufacturing process and washing characteristics of denim, most jeans designs on the market rarely feature colorful and complex patterns. Furthermore, using patches, woven labels, or even embroidery increases the thickness of denim fabric, making it uncomfortable to wear. Therefore, how to better add patterns to denim apparel to increase its styling diversity is the technical problem this application aims to solve. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model proposes a graphic printing tool for denim fabric, which can easily print on denim fabric and present patterns through the colors of the denim fabric itself.

[0004] The technical solution of this utility model is as follows:

[0005] A graphic printing tool for denim fabric includes a front plate and a back plate for setting on both sides of the denim fabric. A first connecting part is provided on the side of the front plate facing the back plate, and a second connecting part is provided on the side of the back plate facing the front plate. The first connecting part and the second connecting part are detachably connected for initially fixing the front plate and the back plate to both sides of the denim fabric.

[0006] Both the front and back panels have connection holes, and the opposite sides of the front and back panels are equipped with rope hooks. The connection holes are used for ropes to pass through, and the rope hooks are used for wrapping and securing the ropes, thereby fixing the front and back panels to both sides of the denim fabric.

[0007] In summary, the above technical solution has the following beneficial effects: The denim fabric graphic printing tool of this application can make corresponding shapes according to the required printing. When in use, the printing tool is initially fixed to both sides of the jeans through the first connecting part and the second connecting part, and then the printing tool is fixed to the denim fabric by the cooperation of the rope and the winding hook. After spraying potassium permanganate around the printing tool, it is put into a water absorber for washing, thereby washing the denim fabric outside the edge of the printing tool to a lighter color. Finally, the printing tool is removed, and the corresponding printed pattern is formed on the denim fabric. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0014] like Figures 1-4 As shown, a graphic printing tool for denim fabric includes a front plate 10 and a back plate 20 for mounting on both sides of the denim fabric. A first connecting part is provided on the side of the front plate 10 facing the back plate 20, and a second connecting part is provided on the side of the back plate 20 facing the front plate 10. The first connecting part and the second connecting part are detachably connected to initially fix the front plate 10 and the back plate 20 to both sides of the denim fabric. Both the front plate 10 and the back plate 20 are provided with connecting holes 30, and both the opposite sides of the front plate 10 and the back plate 20 are provided with rope hooks 40. The connecting holes 30 are used for ropes 1 to pass through, and the rope hooks 40 are used for the ropes 1 to be wrapped and fixed, thereby fixing the front plate 10 and the back plate 20 to both sides of the denim fabric. The denim fabric graphic printing tool of this application can create corresponding shapes according to the required printing. When in use, the printing tool is initially fixed to both sides of the jeans through the first connecting part and the second connecting part. Then, the printing tool is fixed to the denim fabric by the cooperation of the rope and the winding hook. After spraying potassium permanganate around the printing tool, it is put into a water extractor for washing, thereby washing the denim fabric outside the edge of the printing tool to a lighter color. Finally, the printing tool is removed, and the corresponding printed pattern is formed on the denim fabric.

[0015] The printing tool of this application is used for designing irregular patterns on denim fabrics. Through a wash process, including a base color and washing technique, and the creation of either a front plate 10 or a back plate 20 in the desired shape, a flat, perforated graphic is transferred onto the trousers. This process preserves the white pattern, reducing the risk of staining, and achieves a smooth, skin-friendly print, while also being environmentally friendly. Only one of the front plate 10 or back plate 20 needs to be made into the desired shape. The plate of the desired shape is fixed to the front side of the denim fabric to create the corresponding printed pattern. To save costs, the front plate 10 and back plate 20 can be made into two separate shapes. When using the tool, the desired shape is placed on the front side of the denim fabric, allowing one set of printing tools to print two different patterns.

[0016] The specific process is as follows: wash the base color, use environmentally friendly white dye to dye the garment, dye to a certain depth, then fix the color, soap wash, rinse with water to improve the color fastness and gloss, and then dry after the base color is dyed.

[0017] Overall whitening effect after washing: After the garment with the base color has been dried, salt, potassium permanganate concentration adjusted, and humidity combined with physical and chemical methods are used to stir-fry the fabric to create a reddish snowflake-like appearance on the surface. Then, pyroxene and hydrogen peroxide are used as chemical additives to neutralize the white snowflake-like appearance on the trousers.

[0018] Denim fabric printing: Use pre-made printing tools to fix the denim fabric at the desired pattern position. Depending on the requirements, you can use a rope and a sewing needle to pass through the connection hole 30 multiple times to fix it. Then spray potassium permanganate around the printing tool. After spraying, put it in a washing machine to neutralize it with pyroxene and hydrogen peroxide. Then rinse it thoroughly with water multiple times to remove chemical residues and achieve a clear pattern and environmentally friendly overall color effect.

[0019] The denim fabric has been improved in terms of feel: a small amount of softener and fluffing agent has been added to soften the garment, and it feels even better after being air-dried and cooled.

[0020] The printing tool described in this application can be applied to clothing, pants, and any denim fabric.

[0021] The first connecting part is a needle 11, and the second connecting part is a needle hole 21 for inserting the needle 11. In this embodiment, there are multiple needles 11 and needle holes 21, which correspond one-to-one. After the needle 11 on the front plate 10 passes through the denim fabric, it is inserted into the needle hole 21 of the back plate 20 to complete the initial fixation. After the initial fixation, it is convenient to fix it again with a string. After the string is fixed, the printing tool will not separate when it is washed in the washing machine.

[0022] The first connecting part and the second connecting part are magnets 12 that attract each other.

[0023] Both the front plate 10 and the back plate 20 have magnetic grooves on their facing sides for mounting magnets 12. The thickness of the magnets 12 is the same as the depth of the magnetic grooves. In this embodiment, the front plate 10 and the back plate 20 are initially fixed by magnets 12. Since both the front plate 10 and the back plate 20 have magnetic grooves on their facing sides, the facing surfaces of the front plate 10 and the back plate 20 remain flat after the magnets 12 are installed, while still effectively clamping the denim fabric. The two magnets 12 are positioned correspondingly so that the two connecting holes 30 can be aligned. The attached diagram shows two concentric magnets 12 as an example; however, the magnets 12 can be of any shape.

[0024] The cross-section of the rope hook 40 is L-shaped. The L-shaped structure is simple and can effectively secure the rope.

[0025] Both the front plate 10 and the back plate 20 are provided with two rope hooks 40. The bent parts of the two L-shaped rope hooks 40 face opposite directions, which makes it easier to fix the rope winding.

[0026] The two rope hooks 40 on the front plate 10 and the back plate 20 are symmetrically arranged with the connecting hole 30 as the center. The two rope hooks 40 are symmetrically arranged with the connecting hole 30 as the center, which facilitates the winding and fixing of the rope.

[0027] Both the front panel 10 and the back panel 20 have recessed grooves 50 at the cord hooks 40. The depth of the recessed grooves 50 is greater than or equal to the height of the cord hooks 40, ensuring that the highest point of the cord hooks does not exceed the surface of the front panel 10 and the back panel 20. The cord hooks 40 are positioned within the recessed grooves 50, preventing them from protruding beyond the surface of the front panel 10 and the back panel 20. This prevents the cord hooks 40 from damaging the denim fabric when it is placed in a washing machine.

[0028] The recessed groove 50 is circular and concentric with the connecting hole 30. Two centrally symmetrical rope hooks 40 are installed inside the circular recessed groove 50 to facilitate the passing of the rope and its winding and fixing.

[0029] By using the tools in this application to optimize the design of prints on denim fabrics, denim clothing products with a strong sense of design have been created. Compared with existing patterns sewn with needle and thread, it achieves the beneficial effects of zero thickness, better adhesion, and no dye, meeting customers' fashion needs for summer wear. It effectively improves the thickness and appearance of the product, addressing the pain points of thick summer jeans and lack of fashionable products.

[0030] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
