Sweat sweats, which are usually worn when exercising, promote the secretion of sweat into the body, helping the body metabolize and lose weight. These sweat glands are designed to block the heat released from the body to the outside during exercise to maximize sweating by increasing or maintaining body temperature.
For the warmth of the fabric, it is well known that a polyurethane-based coating composition is coated on the surface of a fabric to be applied to sweaters or sports apparel. Typically, there is a wet method in which a resin composition containing a polyurethane and an organic solvent is coated on a fabric to a predetermined thickness and then passed through water to form a film layer having fine pores on the surface of the fabric. Alternatively, a resin composition prepared by dissolving a polyurethane in an organic solvent having high volatility such as acetone, toluene, methyl ethyl ketone or the like is coated to a predetermined thickness on a fabric and then the organic solvent is volatilized by heat treatment to form a uniform film There is a dry method in which a layer is formed on the far-end layer.

INDUSTRIAL APPLICABILITY The present invention has the effect of providing a sweat-absorbing coating composition which is excellent in body temperature retention and sweat discharging effect and has a body fat-decomposing effect by containing an Amphora extract.
The coating composition for sweating according to the present invention comprises (A) a polyurethane resin, (B) an organic solvent, (C) a crosslinking agent, (D) microcapsules containing an ammonia extract, (E) a silane- (F) a fatty acid salt. The coating composition comprising these is adhered to the surface of the fabric in the form of a polyurethane film. The basic resin of the coating composition according to the present invention uses a polyurethane resin (A), and the composition ratio of the other components is determined based on 100 parts by weight of the polyurethane resin.
Preferably, the coating compositions according to the invention are coated in film form and apply a dry coating. Since the polyurethane resin has high viscosity, an organic solvent (B) is mixed and used to form a uniform coating film.
The organic solvent (B) used in the present invention is used for the dissolution and viscosity control of the coating composition. Examples of the applicable organic solvent include toluene, methyl ethyl ketone, dimethyl formamide, isopropyl alcohol, xylene, perchlorethylene, acetone, ethyl acetate, etc. These solvents may be used singly or in combination of two or more . The organic solvent (B) is volatile and evaporates during the formation of the coating film.

At this time, if the viscosity of the organic solvent (B) is less than 2,000 cps, a problem that the coating film is not formed uniformly occurs, and therefore, the viscosity is preferably 2,000 cps or more. In the present invention, the organic solvent (B) is used in an amount of 50 to 250 parts by weight based on 100 parts by weight of the polyurethane resin (A).
The crosslinking agent (C) acts to improve the adhesion between the polyurethane coating film and the fabric or the fabric. Applicable crosslinking agents include polyols, polyamines, polymer capsans, and block isocyanate crosslinking agents. After the coating film is prepared using the coating composition according to the present invention, the coating film is attached to the surface of the fabric or fabric by means of a separate adhesive component. The crosslinking agent has an effect of reinforcing the adhesive force of the separate adhesive component, and the crosslinking reaction is reinforced when the polyurethane coating film is aged. In the present invention, the crosslinking agent (C) is used in an amount of 2 to 10 parts by weight based on 100 parts by weight of the polyurethane resin. When the content of the crosslinking agent is too high, the thickness of the coating film is not constant.
The microcapsules (D) containing the Ampallaya extract are microencapsulated with the Ampallaya extract extracted from Ampallaya fruit or leaves. The Ampalaya extract can be extracted by various methods. For example, in order to obtain an Ampalaya extract, an extract solvent may be added to an Amphala fruit or leaf, followed by hot water extraction, cold-pressing or warm-up extraction. In this case, the extract of Amphiprenaceae is mixed with the extraction solvent at a weight ratio of 2 to 10 times, and the mixture is extracted at 50 to 120 ° C for 1 to 24 hours. At least one selected from water, a lower alcohol having 1 to 4 carbon atoms, a polyhydric alcohol, or a mixture thereof may be used as the extraction solvent.

And a mixture of water and a lower alcohol, a mixture of water and a polyhydric alcohol, a mixture of a lower alcohol and a polyhydric alcohol, or a mixture of water and a lower alcohol and a polyhydric alcohol.
In addition, the Ampalaya extract can be obtained by using a reflux cooling extraction method, an ultrasonic extraction method, a supercritical fluid extraction method, or the like. In addition to the above-described extraction method, an extract obtained through a conventional purification process is also included. For example, an active fraction obtained through various purification methods, such as separation using an ultrafiltration membrane having a constant molecular weight cut-off value, separation by various chromatography, etc., can also be applied as an extract. And the encapsulated process of inserting the extracted Ampalaya extract into the microcapsules.
The microcapsules according to the present invention should have no change in physical properties in the temperature range of the dry polyurethane coating process. That is, it should show heat resistance to about 200 ° C. Further, it is preferable to use spherical particles of solvent resistance which satisfy the insolubility in organic solvents such as toluene, methyl ethyl ketone, dimethyl formamide, isopropyl alcohol, xylene, perchlorethylene, acetone, ethyl acetate and the like.

In the present invention, the microcapsules (D) containing the Ampalaya extract have a diameter in the range of 10 to 100 탆 and are used in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the polyurethane resin. When the diameter is less than 10 탆, it is difficult to directly obtain the effect of the ampullaia extract, and when the diameter exceeds 100 탆, the adhesion of the coating film is deteriorated. As the content of the microcapsules contained in the coating polyurethane resin composition increases, the effect of degrading the body fat by the ammonia extract is improved, but the strength of the coating film is lowered or the possibility of causing defects is increased, The smaller the content of the microcapsules contained in the water is, the better the waterproof performance and the moisture permeability are, but it becomes difficult to obtain the effect of the ammonia extract.
The silane-based organic compound (E) forms a microporous structure formed by self-assembly by modifying the surface of the resin by forming a self-assembled thin film layer at the interface of the polyurethane resin coating film. A non-fluid air layer is formed in the pores to reduce convection in the fabric and heat transfer due to conduction. Examples of such silane-based organic compounds include 3-aminotriethoxysilane, octadecyltrichlorosilane, 3-methacryloxypropyltrimethoxy silane, hexa Hexamethyldisilazane, tridecafluoro-1,1,2,2-tetrahydrooctyl-1-trichlorosilane and tridecafluoro-1,1,2,2-tetrahydrooctyl-1-trichlorosilane. , But it is not necessarily limited thereto, and it is expected that any organic material capable of forming a micropore structure capable of providing the above-mentioned characteristics is applicable. In the present invention, the silane-based organic compound (E) is used in an amount of 1 to 10 parts by weight based on 100 parts by weight of the polyurethane resin.
The fatty acid salt (F) to be applied to the resin composition according to the present invention may be a general-purpose fatty acid salt as an additive for foods, cosmetics and pharmaceuticals. These fatty acid salts improve the quality of the coating layer by removing the unreacted cross-linking agent and modifying the surface of the polyurethane coating layer, thereby improving the performance of the fabric such as moisture permeability and warmth.
Examples of such fatty acids include butyrate, valerate, caprate, enantate, caprate, felargonate, caprate, laurate, myristate, pentadecylate, palmitate, palmitoleate (9,12,15) -linolenic acid salts, (6,9,12) -linolenic acid salts, eleostearates, tuberous stearates, stearates, stearates, oleates, , Arachidonic acid salts, behenic acid salts, lignoceric acid salts, nerbonic acid salts, oleic acid salts, montanic acid salts or melissic acid salts. Among them, laurate, myristate, palmitate, stearate and oleate are preferable. These fatty acid salts may be used singly or in the form of a mixture of two or more kinds thereof. Examples of the organic acid salt include a sodium salt and a potassium salt, and a sodium salt is particularly preferable. In the present invention, the fatty acid salt (F) is used in an amount of 15 parts by weight or less based on 100 parts by weight of the polyurethane resin (A).
