A non-deformation molding process for underwear mold cup and inner layer three-dimensional printed dot embossed pattern

Abstract

The present invention discloses an underwear mold cup and a non-deformation molding process for the inner layer three-dimensional printed dot embossed pattern thereof, comprising a cup body, wherein the cup body is compounded in sequence by an inner layer fabric, an inner layer sponge, an outer layer sponge and an outer layer fabric, wherein the thickness of the inner layer sponge is thinner than that of the outer layer sponge, and the exposed surface of the inner layer fabric is printed and embossed with a plurality of negative ion far-infrared coating dots arranged in a dotted pattern. The present invention divides the sandwich sponge of the cup body into two parts, first compounding the thin sponge with the inner layer fabric and then removing the printed dot embossing, because the extrusion deformation of the thin sponge can be weakened, thereby overcoming the defect of deformation of the printed dot embossed pattern, and finally compounding the thick sponge with the outer layer fabric to ensure the elasticity requirement of the mold cup, thereby completing the mold cup production process, and making the inner layer three-dimensional printed dot embossed pattern non-deformed, thereby improving the wearing effect and visual effect.

Description

Technical Field

[0001] The invention relates to the technical field of underwear mold cups, and more particularly to an underwear mold cup and a non-deformation molding process for an inner layer three-dimensional printed dot embossed pattern thereof. Background Art

[0002] At present, the cup body structure of the mold cup on the market is mostly composed of an inner layer of fabric, an interlayer of sponge and an outer layer of fabric, which are compounded in sequence. There are printed dot embossing patterns in the inner layer of fabric, and some of them have health massage functions, targeting the acupuncture points of the human breast. However, there is no direct printed dot embossing pattern on the inner layer of fabric in the prior art. All of them are a layer of printed fabric sewn on the inner layer of the mold cup. After the printed fabric and the interlayer of sponge are compounded, the position of the printed dot embossing pattern will be more or less deviated and deformed, and the wearing effect and visual effect are not ideal. However, if the inner layer of fabric and the interlayer of sponge are directly compounded and then the printed dot embossing is performed, due to the relatively high elasticity of the interlayer of sponge, the interlayer of sponge will be squeezed and deformed when the upper mold and the lower mold are pressed together. After the printed dot embossing is performed, not to mention that it cannot be printed on the corresponding point, after completion, it will be reset due to the elasticity of the interlayer of sponge, and the printed dot embossing pattern will be deformed accordingly. Summary of the invention

[0003] The purpose of the present invention is to overcome the above defects of the prior art and provide a underwear mold cup and a non-deformation molding process for the inner layer three-dimensional printed dot embossed pattern thereof, wherein the interlayer sponge is divided into two parts, and the thin sponge is first compounded with the inner layer fabric and then the printed dots and embossed patterns are removed. Since the thin sponge can be weakened by extrusion deformation, the defect of deformation of the printed dots and embossed patterns is overcome, and finally a thick sponge and an outer layer fabric are compounded to ensure the elasticity requirement of the mold cup, thereby completing the mold cup production process and making the inner layer three-dimensional printed dot embossed pattern non-deformed, thereby improving the wearing effect and visual effect.

[0004] In order to achieve the above purpose, the present invention is implemented through the following technical scheme: an underwear mold cup, including a cup body, characterized in that the cup body is composited in sequence by an inner layer of fabric, an inner layer of sponge, an outer layer of sponge and an outer layer of fabric, wherein the thickness of the inner layer of sponge is thinner than that of the outer layer of sponge, and the exposed surface of the inner layer of fabric is printed and embossed with a number of negative ion far-infrared coating dots with a dot-shaped layout forming a pattern.

[0005] The present invention divides the sandwich sponge of the cup body into two parts, firstly compounding the thin sponge with the inner layer of fabric and then removing the printing dots and embossing. Since the extrusion deformation of the thin sponge can be weakened, the defect of deformation of the printing dots and embossing patterns can be overcome. Finally, the thick sponge and the outer layer of fabric are compounded to ensure the elasticity requirement of the mold cup, thereby completing the mold cup production process and preventing the inner layer of the three-dimensional printing dots and embossing patterns from being deformed, thereby improving the wearing effect and visual effect.

[0006] The negative ion far infrared coating of the present invention is a silica gel coating made of far infrared powder, tourmaline powder and negative ion powder mixed in a certain proportion. The negative ion far infrared coating can improve blood circulation, neutralize acidic substances produced by sweat, inhibit bacteria and deodorize, and reduce inflammation and relieve itching.

[0007] Preferably, the thickness of the inner sponge is in the range of 2mm to 4mm, and the thickness of the outer sponge is in the range of 8mm to 12mm. The thickness of the inner sponge is critical, that is, it should not be too thick, with sufficient elasticity, so that the printed dots and embossing are deformed during molding; nor should it be too thin, so that it will be completely melted and bonded to the inner fabric during high-temperature molding, losing its composite effect with the outer sponge. In addition, the thickness of the outer sponge is mainly selected to meet the elasticity requirements of the mold cup.

[0008] Preferably, an adhesive layer is coated between the inner fabric and the inner sponge, an adhesive layer is also coated between the inner sponge and the outer sponge, and an adhesive layer is also coated between the outer sponge and the outer fabric. The cup body is a multi-layer structure formed by high-temperature molding technology of the inner fabric, adhesive layer, inner sponge, adhesive layer, outer sponge, adhesive layer, and outer fabric. High-temperature molding technology is currently the most widely used process method on the market and has low cost.

[0009] A non-deformation molding process for the inner layer of a bra cup mold with three-dimensional printed dots and embossed patterns, characterized by comprising the following steps:

[0010] (1) Cutting: Cut out the inner layer of fabric, inner layer of sponge, outer layer of sponge and outer layer of fabric of the same size;

[0011] (2) One-time compounding: the inner layer fabric and the inner layer sponge are compounded by high temperature molding to form a composite inner layer, and then the outer layer sponge and the outer layer fabric are compounded by high temperature molding to form a composite outer layer;

[0012] (3) Dot printing and embossing: The composite inner layer is embossed with dots, and a number of dots are arranged to form a pattern of negative ion far-infrared coating dots on the exposed surface of the inner layer of the composite inner layer;

[0013] (4) Secondary compounding: The inner sponge of the composite inner layer and the outer sponge of the composite outer layer are bonded together and then subjected to high-temperature compression molding to form a finished mold cup.

[0014] Preferably, before the above-mentioned high-temperature molding and compounding work, an adhesive layer is first coated between the inner cloth layer and the inner sponge layer, an adhesive layer is also coated between the inner sponge layer and the outer sponge layer, and an adhesive layer is also coated between the outer sponge layer and the outer cloth layer.

[0015] Preferably, during the high temperature molding and compounding operation, the upper mold temperature is controlled at 165°C to 175°C, the lower mold temperature is controlled at 190°C to 200°C, and the molding time is controlled at 175S to 185S. ​​Since negative ions are added to the printing, the molding temperature cannot be too high, otherwise it will affect the printing effect, so the above variable parameters are preferred.

[0016] Preferably, before the above-mentioned high-temperature molding and compounding work, an adhesive layer is first coated between the inner cloth layer and the inner sponge layer, an adhesive layer is also coated between the inner sponge layer and the outer sponge layer, and an adhesive layer is also coated between the outer sponge layer and the outer cloth layer.

[0017] As a preferred method, before the above-mentioned composite work, the upper mold and the lower mold are modified to increase the positioning structure between the two, add a pair of symmetrically arranged positioning pins in the upper mold, and add a pair of symmetrically arranged positioning holes in the lower mold, and the two positioning pins and positioning holes are matched one by one. Since the printing adopts positioning printing, the requirements for the mold are very high during the molding process, and there must be no left-right or up-down misalignment. Once there is a deviation, a pair of cups will be asymmetrical from left to right. A pair of cups that are asymmetrical from left to right is a defective product. We want to reduce the production of defective products, so positioning points are added to the left, right, top and bottom of the mold to fix the cut pieces.

[0018] Preferably, a pair of symmetrically arranged mold cup holes are arranged in the upper mold and the lower mold, that is, a pair of underwear mold cups are molded together on the left and right sides. Using a pair of cups to be pressed simultaneously is also preferred based on the above-mentioned method of reducing defective products.

[0019] Beneficial effect: The present invention divides the sandwich sponge of the cup body into two parts, firstly compounding the thin sponge with the inner layer of fabric and then removing the printing and embossing. Since the extrusion deformation of the thin sponge can be weakened, the defect of deformation of the printing and embossing pattern can be overcome. Finally, the thick sponge and the outer layer of fabric are compounded to ensure the elasticity requirement of the mold cup, thereby completing the mold cup production process and preventing the inner layer of the three-dimensional printing and embossing pattern from being deformed, thereby improving the wearing effect and visual effect.
