Description
FIELD OF THE INVENTION [0002] The present invention relates to a light exothermic fabric using solar absorption and heat generation.
Recently, there has been a growing demand for apparel products having special value due to changes in consumption patterns that require improvement in living standards, high quality, diversification and differentiation. Especially, when high-performance outdoor clothes are being put to work, Interest is growing.
Also, as denim becomes a fashion product that symbolizes youth, it is worn as clothes to wear throughout the year regardless of the season, but due to its unique cold touch, wearer complaints are caused in autumn and winter seasons. In response to these consumer demands, interest in denim products with warmth and fever functionality has been attracting attention as a complement to the shortcomings of denim products.
The denim products for autumn and winter are mainly used to improve the warmth. They are mainly used to improve the warmth by raising the content of the clothes by brushed on the back side of the skin which touches the skin, and the method of improving the warmth by lowering the air permeability through the windproof coating or film laminating process. Products have been developed and some are sold. Accordingly, it is necessary to develop differentiated denim products with high functionality beyond the general warmth improvement level.
Due to the increase in outdoor activities and the global energy saving movement, there is a growing demand for technologies to add warmth to F / W season and seasonal clothing products. And, as the center of consumption has expanded from the old generation, which was preferring the underwear in the past, to the younger generation, the high functional apparel market is growing rapidly and unlike the previous years where various functionalities were required mainly in synthetic fiber products, The demand is expanding. In addition, due to the warm-feeling functional apparel products that have been developed and sold domestically in developed countries such as Japan, there is a growing interest in products having special heat-generating functions, rather than merely warming-up products in domestic and overseas markets.
The newly developed softness technology for textile products is a technology that uses materials with high energy amount (phase transition material, PCMs) that endotherm or heat up as the material changes from liquid to solid or solid to liquid, Absorption heat generation technology that maximizes the heat generation property while water is adsorbed to the polymer, and body heat reflection technology that reflects radiation heat from the human body have been developed. However, among commercialized products, the content of functional materials (such as PCMs microcapsules and hygroscopic heating fibers) is often small in the actual finished product, and the performance of the product is insufficient depending on the environmental condition and the condition of the wearer, It is a fact that it can not be made. On the other hand, in the production of synthetic fibers such as nylon, polyester and acrylic, there is a method of mixing and radiating light-emitting inorganic particles. These products have excellent durability against washing and abrasion, but they are mainly used in nonwoven fabrics due to technical problems of manufacturing processes such as changing basic physical properties of fibers. Therefore, there is a limitation that the application is limited to clothing products. Due to the nature of the material, it is impossible to respond quickly to the market situation.
The object of the present invention is to develop a processing agent for absorbing sunlight and generating heat (far-infrared ray heat storage) by utilizing sunlight and coating it on a material such as denim suitable for outdoor activities and using it as a light generating material.
It is also aimed to develop a processing agent and associated processing process that gives solar absorption and heat generation functionality to various denim products including jeans for F / W season.
It is also aimed to develop a functional processing agent with color and dispersion stability suitable for denim products.
The present invention relates to the development of a processing agent utilizing inorganic particles having solar absorption and heat generation characteristics and a related processing process. In addition, considering the color and physical properties of denim, materials with excellent solar absorption and heat generation function were selected, and the particle size was adjusted in micro units and nano units to allow for garment processing and printing process application.
The solar light-absorbent exothermic treating agent of the present invention is selected from the group consisting of carbon compounds such as ZrC, SiC and B4C, infrared absorbing composite oxides such as AZO, GZO and AGZO, and Tin compounds such as ATO, ITO, FTO and SnO2 And a dispersion of nanoparticles having an average diameter of 10 to 2000 nm and a fixing agent as one or two or more particles.
The surface of the nanoparticles is coated with 0.1 to 30 wt% SiO 2 of the particles.
The processing agent Characterized in that the light exothermic working dispersion and the coating liquid are mixed in a water-based or non-aqueous system, and the fixing agent is a derivative or a binder and is selected from an aqueous / oil-based acrylic binder and an aqueous polyurethane.
The processing agent of the present invention can be used for coating films, fibers, and fabrics.
The processing agent of the present invention can be applied to fabrics by a method of garment dyeing or printing to process sunlight-exothermic functional fabrics, especially densities.
The amount of the treating agent is preferably 0.1 to 1% by weight of the fabric.
The fabric processed by applying the processing agent of the present invention is characterized in that it has a light heating effect between 1 and 10 ° C. Accordingly, according to the processing method of the present invention, problems that can not be used for fabrics of various colors can be exhibited while maintaining the color of the fibers.
In addition, considering the color and physical properties of denim and other fabrics, materials with excellent solar absorption and heat-generating functions are selected, and micro-units and nano-sized particle-size processing agents are manufactured to enable the application of garments and printing processes .
In the conventional spinning method, since the particles have a particle size of several microns to several tens of microns, the colors that can be processed are limited because they are black. However, according to the processing method of the present invention, the particles have a diameter of 10 to 2000 nm, Since it has stability, it is possible to post-process and it has a merit that the color of fabric does not change because the particle size is small and the mixing ratio is low.

Hereinafter, the present invention will be described in detail.
1. Light absorption And heating functional materials
(UV Spectrophotometer) was measured by irradiating the material having excellent light absorption and exothermic performance.
Solar-absorbing and heat-generating functional fiber products are functional fiber products that absorb sunlight, especially infrared rays, convert them into heat and actively generate heat in response to the external environment. Therefore, when wearing clothing made of these fiber materials during the cold season and absorbing the sunlight during outdoor activities, it can warm up the temperature higher than normal clothes and give a warmth to the wearer.
It is an intelligent processing technology that actively utilizes external environmental conditions. It does not require other energy source such as electric energy and moisture, and exothermic function is manifested only by sunlight naturally received in outdoor activities. And there is an advantage that there is no reaction such as cooling of the fiber material and deterioration of the thermal insulation such as other warm feeling functional processing (phase change material, moisture absorption heat generation, etc.)
Metal is a typical example of a heat generating material, but it is difficult to increase dispersibility of a metal and it is difficult to apply to a fabric because of explosion possibility. The characteristics of inorganic particles, which are known to be related to solar absorption or blocking, are shown in the following table.

Inorganic materials used for such functional processing absorb infrared rays, absorb infrared rays, absorb visible light, emit infrared rays in the form of far infrared rays, and emit infrared rays in the form of far infrared rays, It is known as an ideal material having a high reflectivity in a far infrared ray region having a high absorption rate and a longer wavelength than this.
In the present invention, the solar radiation-absorbing heat generating material is a mixture of a carbon compound such as ZrC, SiC, and B4C, an infrared absorbing complex oxide such as AZO, GZO, AGZO, a Tin compound such as ATO, ITO, FTO, SnO2, Respectively.
2. Light heat Material property evaluation and dispersion test
A dispersion experiment was conducted in a top-down manner using a wet disperser (beads mill) utilizing the light-emitting material of several tens of microns in size from a few microns.
ZrC, SiC and the like were used as the dispersion progressive material. However, it was difficult to secure the self-stability even though it was pulverized to 0.3 μm when dispersed. In order to ensure stability, it was necessary to use a small amount of surfactant.
For the water dispersion type, the particle size was controlled to 30 to 500 nm. For the solvent type, the particle size was adjustable at 3 μm or less. The primary particle size of the dispersing agent was confirmed by FE-SEM (TEM) to check for coarse particles, and the viscosity was controlled to 20 cPs or less for stable application in denim products.
Surfactant (dispersant) to minimize foaming was minimized and dispersed at pH of neutral zone.
In order to ensure dispersion stability of the solvent type and to maximize the light heating effect, the surface of the particles is coated with SiO 2 . The SiO 2 coating is preferably 0.1 to 30 wt% of the light emitting material. ATO coated with silica and ATO coated with silica are 1.5 times or more different in light heat effect when coated on fiber.
The light exothermic processing agent is composed of a finished liquid in which a light-exothermic processing dispersion and a coating liquid are mixed in an aqueous or non-aqueous system, and can be used for manufacturing films, fibers, and clothes.
When coated with a processing agent containing a light-emitting material of the present invention, a light heating effect of 1 to 10 ° C can be obtained.
The coating amount of the photo-thermal processing agent of the present invention is 0.1 to 10 g of light emitting material per 1 kg of film / fiber / clothing.
Fixing agents for fibers (derivatives, binders) used in coating: aqueous / oil-based acrylic binders, aqueous polyurethanes and the like.
3. Process
Up to now, some products have been introduced that produce fibers that incorporate ceramics from a fiber manufacturer, or post-processing (printing, etc.) carbon-based particles on a fabric in post-processing companies.
1) Yarn incorporation: It is a method to mix and emit inorganic particles when manufacturing synthetic fibers such as nylon, polyester, and acrylic. These products have excellent durability against washing and abrasion, but they are used mainly in nonwoven fabrics due to technical problems of manufacturing process, such as changing basic properties of fibers. Therefore, there is a limitation in application to apparel products, and there is a disadvantage in that it is impossible to respond quickly to market conditions due to the nature of the material. That is, coating on existing fabrics is based on the spinning method and has a problem in that the functionality is poor.
2) Post-finishing method: A method of mixing or printing an inorganic particle with a binder such as an acrylic acid-based polymer, a urethane polymer, or a latex and then coating or printing on a yarn, fiber, knitted fabric or nonwoven fabric is mainly used. This method is technically easy but has a disadvantage in that it is not durable against touch, washing and friction.
Generally, in the case of functional clothes, synthetic fibers containing a special functional material are used, or functional processing such as water repellency and antifouling property is performed in the state of a knitted fabric, coating or laminating processing is performed, and such functional fabric is cut and sewn, . However, in the case of denim products, cotton yarn dyed with blue indigo and non-dyed white cotton yarn (or white cotton / polyester blend yarn) are woven with twill fabric using natural fiber cotton fiber It is difficult to use functional synthetic fibers.
In addition, in order to exhibit a unique aesthetic effect of long wearing and discoloration, various physical or chemical methods are used to discolor and embrittle the garment. This process is called washing process, and most of the physical processing methods such as sandblasting and stone washing are combined with chemical processing methods using hypochlorous acid, permanganic acid, and enzymes, which is a method of damaging the fiber itself as well as discoloration. Therefore, it is difficult to use a fabric that has been subjected to functional processing for a denim garment product. In addition, since a garment may be deformed in a garment state, deformed in a button or auxiliary material, or discolored, It is difficult to apply various processes such as physical press bonding and high temperature heat treatment after immersion in a processing agent which has been used as a processing agent.
Therefore, in order to solve these limitations, it is necessary to develop a garment processing technique and a processing agent, and characteristics of the processing agent according to the processing of the present invention are shown in the following table.
Light heat processing agent
- Particle size 200 nm
Appropriate for distribution and storage
Dispersion stability
Light heat processing agent
- Particle size 3 μm or less
In particular, the garment working process in the present invention does not require high temperature heat treatment at 160 DEG C or more like fabric processing, and can be uniformly distributed throughout the product similarly to the dyeing process. Therefore, it is advantageous in that the process is simple, excellent durability is ensured, and there is little influence on the touch and the like, so that it is easy to use as an apparel product.
end. Development of optical absorption and heat processing agent
The heat-generating machining agent of the present invention can be divided into an aqueous dispersion type for garment processing and a solvent dispersion type for printing and coating processes.
In order to stabilize dispersion of particles, water dispersion and solvent type absorption and exothermic processing agent were prepared. Charge control technique using Zeta Potential, minimization of surfactant (dispersant) to reduce foaming and neutralization of pH in neutral region were required .
In the case of using an acidic processing agent in a cotton fiber product, strength degradation is severely caused by cellulose decomposition due to acid during the drying and heat treatment process, and tensile strength and tensile strength of the denim product are frequently deteriorated. The pH standard of KC clothing products (skin-contact clothing products) is 4.0 ~ 7.5.
In order to ensure dispersion stability of the solvent type, the material was surface-treated.
Main particle size needs to be adjusted to improve processing efficiency and touch. The water dispersion type can adjust the particle size from 30nm to 500nm, and the solvent type can control the particle size below 3㎛.
It is necessary to control the particle size and shape to minimize the influence of the denim fabric color, and various materials such as tungsten compound and lanthanum compound which are soft in color are mixed and used.
Suitable fixing agents are anionic, nonionic or cationic compounds, in particular cationic compounds, and also polydiallyldimethylammonium compounds, especially their salts and / or polyacrylates, polyacrylamides and polyvinylpyrrolidones, Copolymers and the like.
I. Processing process technology using development processing agent
One) Garment Dyeing processing
Unlike the conventional method of making clothes by cutting with a dyed fabric, there is also a method of dyeing finished clothes as they are, which is called garment dyeing. In addition, the garment dyeing is not only natural in color, it is also luxurious, and depending on how you manage it under the same conditions, you get different effects, and you can feel more natural and vintage style over time.
The heat generating material nanoparticles of the present invention are mixed with a urethane-based binder such as acrylic urethane resin or polyester urethane resin and dispersed in water to prepare a dispersion.
Such a urethane resin is excellent in cross-linking and rigidity of the urethane bond in the resin, and does not cause damage to the final coating composition without deteriorating the bonding force even when the temperature rises, so that the performance of the coating is not deteriorated even after long- Feature. That is, the heating element material having a constant composition ratio and the binder are mixed well and then subjected to a primary mixing process using a high speed disperser (1,000 rpm for about 20 to 30 minutes for mixing and milling). Thereafter, a 3 roll mill ) Dispersion process, and the dispersion is completed through one pass process.
The hexamethylene diisocyanate was then added and mixed well to adjust the working viscosity. The equipment for dyeing and washing the garment was used to immerse the denim product in the light exothermic processing solution, and then the reaction initiator was put in and heat-treated at a low temperature of 60 ° C. or below.
Since the dispersion contains a small amount of nanoparticles, the washability must be maintained. Therefore, the performance retention ratio was evaluated 20 times after washing according to KS K ISO 6330 (or the care label of the denim product before processing).
2) Printing processing
In the case of zirconium carbide (ZrC), which is known as a known effective material, it is difficult to secure dispersion stability compared with other particles and it is difficult to develop a lightly colored processing agent considering heat generation performance. By using zirconium carbide (ZrC) nanoparticles, it is possible to obtain a heating effect without changing the color of the raw fabric.
Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not to be construed as limiting the scope of the present invention. It will be self-evident.

Further, 3.26 kg of ethyl alcohol was weighed and added, and 392 g of ammonia water was added thereto and mixed. After 5 minutes, 1 kg of TEOS was weighed out and stirred for 12 hours. At this time, 80 wt% of ATO content was used for TEOS. After 12 hours, the silica was evenly coated on the ATO surface and the reaction was terminated. After completion of the reaction, ion species were removed by washing with ultrapure water. The silica - coated ATO was cleaned and dried by removing the silica - coated ATO.
