Description

Technical Field

[0001] This invention relates to the field of textile hygiene protection technology, specifically to a water-soluble protective layer for intimate apparel with a warning destructive structure, including underwear, boxer shorts, bras, bikinis, etc., which can be used to determine whether there has been a trial fitting and to prevent hygiene contamination and resale risks from online shopping returns. Background Technology

[0002] Currently, the widespread problem of "trying on and then returning" is prevalent in online purchases of intimate apparel. When consumers try on items and then return them, it is difficult for merchants to determine whether the items have been used, posing serious hygiene and safety risks. Traditional methods such as hang tags and labels can be easily bypassed, lacking direct, effective, and irreversible indications of usage.

[0003] Therefore, there is an urgent need for a structural innovation that can identify intimate apparel after it has been tried on or washed, thereby improving the ability to detect items that have been tried on. Summary of the Invention

[0004] The purpose of this invention is to provide a water-soluble insulating layer for intimate apparel with a destructive warning structure. Through the dissolution of the membrane in a liquid medium and the irreversible changes in the structural warning module, it enables visual identification of the wearing or washing behavior, effectively preventing resale.

[0005] This invention provides a water-soluble insulating layer for intimate apparel with a warning-inducing destructive structure. The garment includes a main body and a water-soluble insulating layer disposed in the crotch area or bra cups. Specific features include: the water-soluble insulating layer can be made of controllable soluble polymer materials such as polyvinyl alcohol (PVA), polyethylene oxide (PEO), water-soluble cellulose, polyacrylates, and alginates, possessing cold-water or hot-water solubility. The insulating layer can be processed into a water-soluble film, water-soluble nonwoven fabric, or applied to the surface of the intimate apparel fabric through spraying, coating, hot pressing, or lamination to form a bonded insulating structure, achieving overall insulating function. The film thickness of the insulating layer is 0.01mm to 0.5mm, and it can be fixed to the surface of the intimate apparel main body or in the interlayer structure through sewing, adhesive application, hot melting, hot pressing, screen printing, or adhesive lamination.

[0006] The "coating" method refers to pre-compositing or spraying a water-soluble film onto clothing fabric, which is then cut into finished products to form an integrated bonding structure.

[0007] The water-soluble insulating layer of the suggestive structure has one or more of the following structures on its upper or lower surface for enabling try-on identification: 1. Graphic and text exposure structure: Irreversible warning graphics and text are set on the inner clothing fabric below the water-soluble isolation layer or in contact with it by means of graphic printing, heat transfer, laser engraving, etc., and are exposed after the film dissolves.

[0008] 2. Vanishing Text / Image Structure: Content is printed on the water-soluble isolation layer using water-soluble or thermochromic ink, and the text or image disappears upon contact with water.

[0009] 3. Color-changing indicator structure: A thermosensitive / water-sensitive color-changing material is printed on the surface of the water-soluble isolation layer. The material will change color (such as red) when exposed to liquid or body temperature changes, providing a clear indication.

[0010] 4. Sticker warning structure: Thermal paper, graphic stickers, or transparent warning stickers are adhered to the surface of the water-soluble isolation layer or on it. After dissolving or washing with water, the stickers may fall off, deform, or the warning content may become invalid.

[0011] 5. Drop warning structure: A warning pendant is installed on the water-soluble isolation layer and fixed by sewing hooks or water-soluble adhesive. When it comes into contact with liquid, the connection fails and the pendant will automatically fall off, forming an irreversible warning.

[0012] 6. Embroidery peeling structure: The prompt pattern is directly embroidered on the water-soluble isolation layer, and after washing, it will peel off or become ineffective along with the film layer.

[0013] 7. Embossed Indication Structure: A raised or recessed pattern (such as "ABCD") is formed on the water-soluble isolation layer using high-pressure hot pressing technology. After washing, the film layer disappears, and the indication disappears as well. Alternatively, the content can be pressed onto the garment body under the film layer using high-pressure hot pressing, and the indication image and text will appear after dissolution.

[0014] 8. Laser-engraved prompt structure: Prompt content can be set on the water-soluble isolation layer body by laser engraving or graphic engraving, and the content will disappear after the film dissolves; alternatively, prompt content can be engraved on the clothing fabric body below the film layer, which will appear after the film dissolves, forming an irreversible identification.

[0015] Note: The warning structure can be independently installed on the upper surface, lower surface, or interlayer of the water-soluble barrier membrane, or it can be used in combination. The membrane structure remains unchanged; functional expansion is achieved by adding modular warning components, effectively preventing circumvention of the scope of protection of this invention through structural replacement or functional splitting. Alternatively, this invention can omit the warning structure and use only the water-soluble membrane as an anti-trial-wear barrier layer.

[0016] Scope of application: Applicable to all kinds of intimate apparel, including but not limited to: Women's underwear (including briefs, boxer briefs, and boxer briefs); Men's underwear (including briefs, boxer briefs, and boxer briefs); Children's underwear (including briefs, boxer briefs, and boxer briefs); Women's bras and sports underwear; • Bikini swimwear and other close-fitting clothing.

[0017] The intimate apparel mentioned is not limited to the above categories. Any garment with a structure that fits in close contact with the human body can be identified and prompted using the technical solution of this invention.

[0018] All of the above structures can be designed using a unified principle and implemented by referring to underwear structural drawings, without the need for repeated drawing. Example of an embodiment

[0019] Example 1: The bra cup structure has a water-soluble film covering the inner side of the cup, which is fixed with adhesive and the surface is screen-printed with thermal ink graphics. After washing or wearing, the film dissolves and the text disappears.

[0020] Example 2: The crotch area of ​​the bikini bottom is covered with a film-type PVA water-soluble film with an embossed heart pattern. After washing, the film dissolves, and the pattern disappears, indicating the need for use.

[0021] Example 3: The crotch area of ​​the children's boxer shorts is lined with a water-soluble film, and a hanging tag is sewn on the outside. Even if the tag falls off upon first wear due to contact with bodily fluids, leaving a wear mark, this will prevent the shorts from showing signs of use.

[0022] Example 4: The text "Try it on and it will not come back" is laser-engraved on the bra cup fabric under the lower layer of the graphic display structure membrane. The text appears after the membrane is dissolved.

[0023] Example 5: A heat-sensitive sticker is attached to the water-soluble film of the underwear reminder structure, which falls off upon contact with water. It can also be combined with color-changing graphics and text to achieve a contextual reminder effect.

[0024] Beneficial effects • Tears after one wear, irreversible, includes irreversible fitting warning. • No user intervention is required; the structure changes automatically. • Compatible with different clothing categories, widely applicable • Significantly enhances consumers' confidence in the hygiene of online purchases of intimate apparel; • The cost structure is controllable, making it suitable for large-scale sales scenarios such as e-commerce.
