Description

Technical Field

[0001] This invention relates to the field of silicone product processing, specifically to a silicone underwear body and its processing technology. Background Technology

[0002] With social development and improved living standards, people's pursuit of beauty is also increasing. Wearable silicone underwear, particularly for cosplay (anime character role-playing), cross-dressing performances, and is widely accepted and used by patients with burns and those who have undergone surgery. Currently, most wearable silicone underwear products on the market have a smooth, flat inner surface. Because silicone is a one-piece injection molded material, the product is not breathable. This smooth surface adheres tightly to the wearer's skin, making it difficult for sweat to escape, causing the silicone to stick to the skin and resulting in a sticky, burning, and restrictive feeling. In dry environments, friction between the silicone and the skin can generate static electricity, leading to dry skin and potentially symptoms such as redness, swelling, and itching after prolonged wear. Silicone also has poor thermal conductivity, making it very cold to wear in winter, affecting comfort and overall feel. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, a silicone underwear with flocked inner surface includes, from the outside to the inside, a silicone underwear body 1, a silicone surface treatment layer 2, a silicone adhesive layer 3, and a flocked layer 4.

[0027] In this application, the method for manufacturing silicone underwear with flocked inner surface is carried out according to the following steps:

[0028] (1) Clean the silicone underwear body; first clean the oil stains and dirt on the surface of the silicone underwear, put the inner surface of the silicone underwear on the mold frame, and then use an air gun or oven to blow or dry the moisture on the surface of the silicone underwear.

[0029] (2) Spray silicone surface treatment agent onto the inner surface of the silicone underwear; in an operating environment of 20±5℃ and 65% humidity, use a spray gun to evenly spray the silicone surface treatment agent onto the inner surface of the silicone underwear. The distance between the spray gun and the inner surface of the silicone underwear is 10-15cm, and the spraying movement time is 0.5-1 second; move the spray gun up and down or left and right at a uniform speed, and 1-2 passes will be sufficient to obtain the silicone surface treatment layer 2.

[0030] Silicone surface treatment agent (JH-1706 silicone treatment agent) can effectively improve the surface properties of silicone and enhance the adhesion effect.

[0031] Prepare a silicone adhesive (viscosity value of 30000 cps) and spray it onto the silicone surface treatment layer 2. Mix the silicone adhesive in an environment of 20±5℃ and 65% humidity. The mixing ratio of agent A, agent B (using Kanglibang AB two-component silicone adhesive, or adhesives from other manufacturers), and diluent (xylene or white spirit) is 3.5:3.5:3. Under these conditions, use a high-pressure spray gun with a nozzle diameter of 2.0-3.0mm to evenly spray the silicone adhesive onto the inner surface of the silicone underwear that has been treated. The distance between the spray gun and the inner surface of the silicone underwear should be 10-15cm, and the spraying movement time should be 0.5-1 second. Move the spray gun up and down or left and right at a uniform speed, 1-2 passes are sufficient. The operation time should be controlled within 3-8 minutes to obtain the silicone adhesive layer 3.

[0032] (3) Use an electrostatic flocking machine to flock fibers (super soft short-pile flocking, viscose flocking, or cotton flocking) onto the inner surface of the silicone underwear body with silicone adhesive; in an operating environment of 20±5℃ and 65% air humidity, use an electrostatic spray gun flocking device to flock fibers onto the inner surface of the silicone underwear. The distance between the spray gun and the inner surface of the silicone underwear is 10-15cm, and the spraying movement time is 1-1.5 seconds; move the spray gun up and down or left and right at a uniform speed, and 3-4 passes will obtain the flocked layer 4.

[0033] (4) Place in an oven for high-temperature baking; baking involves vulcanizing at 150℃-160℃ for 10-15 minutes and curing at around 80℃ for 30-40 minutes. Baking allows the adhesive to cure quickly, and it takes about 24 hours to cure at room temperature.

[0034] (1) Clean the silicone underwear body by removing dust and lint. At room temperature, clean the flocked silicone underwear body by removing dust and lint. Use an air gun or a soft brush to clean the flocked surface and remove excess lint and dust.

[0035] In this application, the flocking fibers on the inner surface have a length of 0.2-3 mm and a thickness of 0.8-20D.

[0036] In this application, the silicone underwear body can be shorts, upper body underwear, lower body underwear, or bodysuit. Of course, the silicone inner body can be a men's silicone underwear or a women's silicone underwear, such as... Figure 2 As shown, the chest cavity of the female silicone bra body is filled with silicone dressing 5 and sealed with adhesive strips.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
