Description

Description
WATERPROOF CLOTH WITH KEEPING WARM FUNCTION
Technical Field
[1] The present invention relates, generally, to cloth having a heat insulation function, and, more particularly, to waterproof breathable cloth having a heat insulation function, which is advantageous because it has excellent breathability, allowing sweat to escape, and high waterproofness while blocking the infiltration of external heat and cool air, to provide heat insulation. Background Art
[2] In general, waterproof breathable cloth functions to allow water vapor such as sweat to easily escape while effectively preventing the infiltration of water drops, and is thus used as a material (cloth) for clothes worn during extreme exercise in poor weather conditions, such as sports wear, climbing wear and ski wear.
[3] Further, the waterproof breathable cloth requires high water pressure resistance and high breathability, so as to have a fine wearing feel at all times by blocking the in¬ filtration of rain drops during rain and maintaining a uniform temperature in the clothes through dissipation of perspiration from the body in high temperature en¬ vironments due to extreme exercise while the body temperature in the clothes is kept constant in low temperature environments.
[4] Conventional techniques for preparing such waterproof breathable cloth are classified into (a) a wet process, comprising mixing polyurethane with dimethyl- formamide as an organic solvent to prepare a resin composition, which is then applied on cloth to a predetermined thickness and then passed through water, thus forming a polyurethane coating layer having very small pores on the cloth; (b) a dry process, comprising dissolving polyurethane in a highly volatile organic solvent, such as methylethylketone, toluene, acetone or isopropylalcohol to prepare a resin composition, which is then applied on cloth to a predetermined thickness and then heat treated to volatilize the volatile organic solvent, thereby forming a uniform polyurethane film layer on the cloth; and (c) a laminating process, comprising preparing a waterproof breathable film, which is then laminated on cloth using an adhesive.
[5] Each of the conventional waterproof breathable types of cloth prepared using the above processes has the two-layer structured section as shown in FIG. 1. As is apparent from FIG. 1, the conventional waterproof breathable cloth has a two-layer structure formed by applying or laminating a polyurethane resin layer 2 having breathability and waterproofness on synthetic fabric cloth 1. [6] Although the conventional techniques may be suitable for the exhibition of some breathability and waterproofness, they do not realize heat insulation. Therefore, the conventional techniques are disadvantageous because the temperature in the clothes cannot be maintained uniform, and do not impart antibiotic activities and deodorization functions.
Disclosure of Invention Technical Problem
[7] Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide waterproof breathable cloth having a heat insulation function, which is ad¬ vantageous because a waterproof layer and a heat insulation coating layer are laminated on cloth, thus blocking the infiltration of external heat and cool air for heat insulation while having high breathability, allowing sweat to easily escape, with water¬ proofness, antibiotic activity and deodorization functions. Technical Solution
[8] In order to achieve the above object, the present invention provides waterproof breathable cloth having a heat insulation function, comprising release paper; a first coating layer, formed by coating the upper surface of the release paper with a composition composed mainly of a one-component hydrophilic non-porous polyurethane resin; a second coating layer, formed by coating the upper surface of the first coating layer with a mixture composition composed mainly of a two-component hydrophilic non-porous polyurethane resin, a styrene monomer, and dimethy- laminoethyl methacrylate; and cloth, attached to the upper surface of the second coating layer, in which the release paper is removed when the waterproof breathable cloth is used.
[9] The waterproof breathable cloth preferably further comprises an adhesive layer, formed by coating the upper surface of the cloth with an adhesive composition composed mainly of a two-component hydrophilic non-porous polyurethane resin using a mesh-printing laminating process; and lamination cloth, attached to an upper surface of the adhesive layer.
[10] In the waterproof breathable cloth, the first coating layer may comprise 65-80 wt% of the one-component hydrophilic non-porous polyurethane resin, 13-19 wt% of methylethylketone, 2-4 wt% of a one-component polyurethane resin toner, 2-4 wt% of tourmaline, 2-4 wt% of germanium, and 2-4 wt% of ceramic, mixed together, and the second coating layer may comprise 35-42 wt% of the two-component hydrophilic non-porous polyurethane resin, 8-11 wt% of methylethylketone, 0.5-3 wt% of a melamine formaldehyde crosslinking agent, 0.1-2 wt% of an amino accelerator, 20-30 wt% of the styrene monomer, 14-16 wt% of dimethylaminoethyl methacrylate, 2-4 wt% of 2-propionic acid, 2-3 wt% of benzoyl peroxide, 2-3 wt% of alumina, 1-2 wt% of TX oxide, 0.02-0.1 wt% of polyethylene glycol, and 0.05-0.1 wt% of organo- modified polysiloxane, mixed together. In addition, the adhesive layer may comprise 78-88 wt% of the two-component hydrophilic non-porous polyurethane resin, 10-20 wt% of methylethylketone, 0.5-3 wt% of a melamine formaldehyde crosslinking agent, and 0.1-1 wt% of an amino accelerator, mixed together. Advantageous Effects
[11] The present invention provides waterproof breathable cloth having a heat insulation function, which is advantageous because the infiltration of external heat and cool air is blocked for heat insulation, and simultaneously, excellent breathability, allowing sweat to easily escape, is exhibited, resulting from the lamination of a waterproof layer and a heat insulation coating layer on cloth.
[12] In addition, the cloth of the present invention has antibiotic activity and de- odorization functions, and may also emit anions and far infrared rays. Brief Description of the Drawings

As shown in this drawing, the waterproof cloth of the present invention comprises release paper 100, a first coating layer 110, a second coating layer 120, and cloth 130. In the waterproof breathable cloth, the term "two layers" means the total coating layers, each of which represents the first coating layer 110 and the second coating layer 120.
[18] The first coating layer 110 is formed on the release paper 100, using a composition prepared by mixing 65-80 wt% of a one-component hydrophilic non-porous polyurethane resin in which a solid content is 30-35%, 13-19 wt% of methylethylketone, 2-4 wt% of a one-component polyurethane resin toner, 2-4 wt% of tourmaline, 2-4 wt% of germanium, and 2-4 wt% of ceramic. The one-component hy¬ drophilic non-porous polyurethane resin has a viscosity of 600-700 poise. [19] The composition thus prepared is applied on the release paper 100 using a comma knife or by a laminating process.
[20] As such, the composition is applied in an amount of 130-170 g/D. The applied composition is dried at about 140~160°C for 1-2 min. That is, the first coating layer 110 removes the solvent therefrom while passing through a drying line, thereby forming a desired first coating layer 110, which exhibits far infrared emission, antibiotic activity, anion emission, deodorization, breathability and waterproofness.
[21] After the formation of the first coating layer 110, the second coating layer 120 is formed on the first coating layer 110.
[22] The composition for use in the formation of the second coating layer 120 comprises
35-42 wt% of a two-component hydrophilic non-porous polyurethane resin, 8-11 wt% of methylethylketone, 0.5-3 wt% of a melamine formaldehyde crosslinking agent, 0.1-2 wt% of an amino accelerator, 20-30 wt% of a styrene monomer, 14-16 wt% of dimethylaminoethyl methacrylate, 2-4 wt% of 2-propionic acid, 2-3 wt% of benzoyl peroxide, 2-3 wt% of alumina, 1-2 wt% of TX oxide, 0.02-0.1 wt% of polyethylene glycol, and 0.05-0.1 wt% of organo-modified polysiloxane, mixed together.
[23] As the two-component hydrophilic non-porous polyurethane resin, a resin in which a solid content is 50-55% is used, with a viscosity of 300-400 poise.
[24] When the second coating layer 120 is formed using the above composition, the composition is applied in an amount of 150-200 g/D, and the applied composition is dried at about 140~160°C for 1-2 min. The second coating layer 120 removes the residual solvent therefrom while passing through a drying line, thereby forming a desired second coating layer 120, which exhibits breathability, waterproofness and heat insulation.
[25] On the second coating layer 120, the cloth is applied, which includes, for example, natural fabric, or artificial fabric.
[26] The cloth 130 is applied on the second coating layer 120 using a laminating process, after which it is cured at about 50~60°C for 24 hr.
[27] After the completion of the above procedures, when the waterproof breathable cloth thus obtained is used, the release paper 100 is removed .
[28] As mentioned above, although the waterproof breathable cloth having two layers is proposed, waterproof breathable cloth having three layers may also be provided, and the description thereof is as follows.
[29] As shown in FlG. 3, the waterproof breathable cloth having three layers comprises release paper 100, a first coating layer 110, a second coating layer 120, cloth 130, an adhesive layer 140, and lamination cloth 150.
[30] As such, the release paper 100, the first coating layer 110, the second coating layer
120 and the cloth 130 are layered in the same manner as in the waterproof breathable cloth having two layers, and thus the description thereof is omitted.
[31] In the waterproof breathable cloth, the term "three layers" means the total coating layers, each of which represents the first coating layer 110, the second coating layer 120, and the adhesive layer 140.
[32] The waterproof breathable cloth having three layers is formed by sequentially laminating the adhesive layer 140 and the lamination cloth 150 on the waterproof breathable cloth having two layers, which includes the first coating layer 110 formed on the release paper 100, the second coating layer 120 formed on the first coating layer 110, and the cloth 130 formed on the second coating layer 120.
[33] The adhesive layer 140 is formed on the cloth 130, and the composition constituting the adhesive layer 140 is composed of 78-88 wt% of a two-component hydrophilic non-porous polyurethane resin, 10-20 wt% of methylethylketone, 0.5-3 wt% of a melamine formaldehyde crosslinking agent, and 0.1-1 wt% of an amino accelerator, mixed together. The two-component hydrophilic non-porous polyurethane resin has a viscosity of 300-400 poise.
[34] When the adhesive layer 140 is formed using the above composition, the composition is applied in an amount of 100-120 g/D. The applied composition is dried at about 80~140°C for 0.5-1 min. The composition for the adhesive layer 140 is applied on the cloth using a mesh-printing laminating process, thus forming a mesh type adhesive layer 140. In addition, the adhesive layer 140 removes the residual solvent therefrom while passing through a drying line, thereby completing a desired adhesive layer 140 having breathability and waterproofness.
[35] In addition, the lamination cloth 150, which is formed on the adhesive layer 140, includes, for example, natural fabric or artificial fabric.
[36] The lamination cloth 150 is formed on the adhesive layer 140 using a laminating process, and is then cured at about 70~80°C for 24 hr.
[37] After the above procedures are completed, the waterproof breathable cloth having three layers comprises, sequentially moving upwards, the release paper 100, the first coating layer 110, the second coating layer 120, the cloth 130, the adhesive layer 140 and the lamination cloth 150. When the cloth thus obtained is used, the release paper 100 is removed. Mode for the Invention
