Therefore, it can be washed with water, is not easy to wrinkle, has a very small radial shrinkage rate, is not easy to get stained, and has a better antibacterial effect.

[0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to provide a washable suit, including a suit body, wherein the suit body includes a wrinkle-resistant layer, an outer fabric layer is disposed on one side of the wrinkle-resistant layer, and an inner fabric layer is disposed on the other side of the wrinkle-resistant layer; the wrinkle-resistant layer is made by soaking cotton fabric in a polyaspartic acid ester resin solution and then treating it at high temperature, and a plurality of diamond-shaped through holes are evenly distributed on the cotton fabric; a non-woven fabric layer is disposed between the wrinkle-resistant layer and the outer fabric layer, and a non-woven fabric layer is disposed between the wrinkle-resistant layer and the inner fabric layer.

[0005] Furthermore, the general formula of the polyaspartic acid ester resin structural monomer is:

[0006]

[0007] Wherein, R is an alkyl group and X is a straight-chain or alicyclic carbon chain structure.

[0008] Furthermore, the basis weight of the anti-wrinkle layer is 50-80 g / m². 2 The radial shrinkage rate is 1%-1.5%.

[0009] Furthermore, by weight, the polyaspartic acid ester resin solution contains 50-60 parts of polyaspartic acid ester resin and 350-400 parts of water.

[0010] Furthermore, the outer fabric layer comprises a blend of wool and polyester, with 60-70 parts by weight of wool and 30-40 parts by weight of polyester; the inner fabric layer comprises wool and polyester, with 60-70 parts by weight of wool and 30-40 parts by weight of polyester; and micro-hooked protrusions are formed on the outer surfaces of the outer and inner fabric layers that are in contact with the anti-wrinkle layer.

[0011] Furthermore, an inner lining cotton layer is provided on the side of the inner fabric layer away from the outer fabric layer.

[0012] To solve the above-mentioned technical problems, the present invention also provides a method for manufacturing the above-mentioned washable suit, which includes the following steps: S1: cotton fabric with multiple diamond-shaped through holes evenly distributed is treated at high temperature using a polyaspartic acid ester resin solution to obtain a wrinkle-resistant layer; S2: non-woven fabric is bonded to both sides of the wrinkle-resistant layer using an environmentally friendly water-based waterproof adhesive and a laminating machine; S3: on the side where the two non-woven fabrics are far apart, an outer fabric layer and an inner fabric layer are also bonded to each other using an environmentally friendly water-based waterproof adhesive and a laminating machine.

[0022] The present invention is further described below through specific embodiments, but this is not intended to limit the scope of the invention. All components described in the present invention are commercially available.

[0023] Figure 1 This is a schematic diagram of the structure of the washable suit of the present invention; Figure 2 This is a partial cross-sectional view of the washable suit of the present invention. Figure 3 This is a schematic diagram of the anti-wrinkle layer structure of the washable suit of the present invention.

[0024] Please see Figure 1 , Figure 2 and Figure 3 The present invention provides a washable suit, including a suit body, wherein the suit body includes a wrinkle-resistant layer 3, an outer fabric layer 1 is provided on one side of the wrinkle-resistant layer 3, and an inner fabric layer 4 is provided on the other side of the wrinkle-resistant layer 3.

[0025] The anti-wrinkle layer 3 is made by soaking cotton cloth 7 in a polyaspartic acid ester resin solution and then treating it at high temperature. Multiple rhomboid through holes 6 are evenly distributed on the cotton cloth 7.

[0026] A non-woven fabric layer 2 is provided between the wrinkle-resistant layer 3 and the outer fabric layer 1, and a non-woven fabric layer 2 is provided between the wrinkle-resistant layer 3 and the inner fabric layer 4.

[0027] The washable suit provided by this invention uses a polyaspartic acid ester resin monomer with the following general formula:

[0028]

[0029] Wherein, R is an alkyl group and X is a straight-chain or alicyclic carbon chain structure.

[0030] Radial shrinkage refers to the reduction in length (i.e., radial) of a fabric after processing, soaking in water for a certain period, and then naturally drying. It is usually expressed as a percentage. For cotton fabric, its radial shrinkage is affected by various factors such as fiber hygroscopicity, fabric density, yarn count, and manufacturing process. In national standards, the warp (radial) shrinkage rate for first-grade cotton fabric is generally specified as 3%. This means that after washing, the cotton fabric will shorten to a certain extent in the length direction, and obviously cannot be directly used as the main body of the anti-wrinkle skeleton. This invention significantly reduces the radial shrinkage rate by treating cotton fabric 7 with polyaspartic acid ester resin and water at high temperature. The anti-wrinkle layer 3 obtained by this invention can achieve a weight of 50-80 g / m². 2 The radial shrinkage rate is 1%-1.5%.

[0031] The washable suit provided by the present invention comprises, by weight, 50-60 parts of polyaspartic acid ester resin and 350-400 parts of water in the polyaspartic acid ester resin solution.

[0032] The washable suit provided by the present invention includes an outer fabric layer 1 comprising a blend of wool and polyester, wherein, by weight, the wool comprises 60-70 parts and the polyester comprises 30-40 parts.

[0033] The inner fabric layer 4 comprises wool and polyester, with 60-70 parts by weight of wool and 30-40 parts by weight of polyester.

[0034] Micro-hook-shaped protrusions are formed on the outer surfaces of the outer fabric layer 1 and the inner fabric layer 4 that are in contact with the anti-wrinkle layer 3.

[0035] The washable suit provided by the present invention has an inner cotton lining layer 5 on the side of the inner fabric layer 4 away from the outer fabric layer 1, which provides the suit with a certain degree of warmth; the outer fabric layer 1 and the inner fabric layer 4 are skin-friendly, making the wearer comfortable.

[0036] The present invention also provides a method for manufacturing the above-mentioned washable suit, comprising the following steps:

[0037] S1: Cotton fabric 7 with multiple diamond-shaped through holes 6 evenly distributed is treated at high temperature with polyaspartic acid ester resin solution to obtain wrinkle-resistant layer 3.

[0038] S2: Non-woven fabric 2 is bonded to both sides of the anti-wrinkle layer 3 using environmentally friendly water-based waterproof adhesive and a laminating machine;

[0039] S3: On the side where the two non-woven fabrics 2 are far apart from each other, the outer fabric layer 1 and the inner fabric layer 4 are also bonded together by environmentally friendly water-based waterproof adhesive and a laminating machine.

[0040] S4: Install the inner lining cotton layer 5 on the side of the inner fabric layer 4 that is away from the outer fabric layer;

[0041] S5: Cut the fabric obtained in S4 to prepare a washable suit according to the preset size.

[0042] The present invention provides a method for manufacturing a washable suit, wherein step S1 includes the following steps:

[0043] Soaking: Prepare a solution with 50-60 parts of polyaspartic acid ester resin and 350-400 parts of water, and heat it to 120-170℃. Soak the cotton cloth 7 completely in the solution so that the cotton cloth 7 is in full contact with the solution.

[0044] Drying: Remove the soaked cotton cloth 7 and place it in a dryer to dry until dry;

[0045] Bleaching: Soak the dried cotton cloth 7 in bleaching water for 20-30 minutes;

[0046] Washing and dehydration: Wash and dehydrate the bleached cotton fabric 7.

[0047] The present invention provides a method for manufacturing a washable suit, wherein the outer fabric layer 1 and the inner fabric layer 4 are made of wool and polyester blend. During the blending process, the wool and polyester on one side are cut and overfed to form micro-hook-shaped protrusions. Then, the side with the micro-hook-shaped protrusions is bonded to the non-woven fabric 2. In step S3, hot melt adhesive is uniformly applied to the wrinkle-resistant layer 3 and one side of the non-woven fabric 2 to bond the inner fabric layer 4, and dried at 100-120℃ for 2-5 minutes. Then, hot melt adhesive is uniformly applied to the wrinkle-resistant layer 3 and the other side of the non-woven fabric 2 to bond the outer fabric layer 1, and dried at 140-150℃ for 2-5 minutes. In this way, the micro-hooked protrusions on the surfaces of the outer fabric layer 1 and the inner fabric layer 4 can penetrate deep into the diamond-shaped through-holes 6 on the nonwoven fabric 2 and the anti-wrinkle layer 3, forming more bonding points. This not only prevents slippage between fibers but also makes the bonding between the layers tighter, resulting in a more flattering shape. Therefore, it can be washed without wrinkling and has a very low radial shrinkage rate. At the same time, the tensile strength can be improved by double-dry bonding and increasing the heating temperature of the second drying bonding. This is because at high temperatures, the micro-hooked protrusions on the surfaces of the outer fabric layer 1 and the inner fabric layer 4 can better diffuse into the nonwoven fabric 2 and the diamond-shaped through-holes 6, forming a tightly packed, intersecting three-dimensional mesh structure. Therefore, it is not easily stained and has a better antibacterial effect.

[0125] In summary, the polyaspartic acid ester resin, water, and high-temperature combination used in this invention make the cotton fabric less prone to folding, and the resulting wrinkle-resistant layer can return to its original state without easily forming wrinkles. Furthermore, it has a low radial shrinkage rate, is very environmentally friendly, odorless, and harmless to the human body. Its elasticity is 2-3 times stronger than that of ordinary resin formulations. The diamond-shaped through-holes in the cotton fabric not only allow for a very thin and lightweight wrinkle-resistant layer, with a weight as low as 50-80 g / m², but also contribute to its superior performance. 2 This ensures a tighter fit between the layers, a more flattering fit, and does not affect breathability. The non-woven fabric on both sides also helps to inhibit bacterial growth.
