Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of producing a durable composite fabric for marine leisure,

The present invention relates to a method for producing a high-durability composite fabric for marine leisure, and more particularly, to a method for manufacturing a marine leisure high-durability composite fabric, (Internal) material, and a method for manufacturing a high-durability composite fabric for marine leisure used in protection and storage covers of marine facilities including ships.

In recent years, as people's living standards have improved and income has increased, interest in various marine leisure has been greatly increased. In particular, Korea is surrounded by the sea on three sides and has optimal conditions for marine leisure activities.

The marine leisure industry is another high-value-added industry in the future, and the interest is being amplified. As a result, the number of license holders of the domestic power-powered water and leisure organizations exceeds 100,000, and Korea is also experiencing the maritime leisure age in earnest .

According to statistics of the World Ocean Industries Association (ICOMIA), the global market size of the marine leisure industry is rapidly growing from 23 million to $ 47 billion in 2006 to 27.1 million and $ 75.1 billion in 2010, The number of reserves has increased by 1.03 million per year, making the marine leisure industry one of the "Blue Ocean" industries.

The size of domestic marine leisure equipment (yacht, boat, etc.) doubled from 4,178 in 2005 to 8,232 in 2010, and it is expected to increase to 25,700 in 2019, creating about 700 billion market.

In Korea, however, unlike the leading position in the shipbuilding industry, the technology of the marine leisure industry is far behind that of the advanced countries. Therefore, major parts of marine leisure vessels such as yachts and boats and related auxiliary materials Most depend on overseas imports.

Korean Patent No. 10-1174593 discloses a patent relating to an embroidering fabric.

On the other hand, marine leisure vessels, which are increasing rapidly in recent years, are mostly made of fiber reinforced composites, which are light and high in strength. However, they are most vulnerable to sunlight (ultraviolet rays).

Therefore, as interest in marine leisure is increasing, there is a great demand for marine fabric products for marine leisure used in yacht, boat, cruise, leisure vessel, beach facility, and building.

Awareness is basically a product that creates a shining effect by fabric (fabric). It is usually installed on the entrance of the building and windows to control the solar radiation amount and to block the rain.

Fabrics used for marine leisure are largely used for the protection of marine facilities including marine vessels (bimini, parasol, etc.) and interior (interior) materials as well as marine facilities and marine facilities such as yacht, boat, And a storage cover.

For marine leisure fabrics, more demanding requirements are required than general purpose fabrics, but technology investment and development are difficult due to the small size of related subsidiary materials (textile materials).

In addition, although the prior art embroidering fabric according to the prior art is applied with a PVC coating method, it is replaced with a PU coating and a fluorine-based coating due to the controversy of hazardousness such as generation of an environmental hormone as a raw material used as a plasticizer of a coating resin and use of an organic solvent. It is used only in special fields because of high cost.

The present invention is conceived to overcome the problems of the prior art described above. In marine fabric materials for marine leisure where high strength and shape stability are required, it is generally possible to use acrylic or PET fabrics to produce PVC, PU coating, Coating technology, and we design and apply high tenacity PET fabric and tricot knitted fabric for marine leisure applications.

In addition, by selecting and modifying environment-friendly polymer-coated resin which is free from the conventional PVC coating method and free from the occurrence of no plasticizer and yellow horn hormone, it has developed a high performance, high weatherability marine leisure And to provide a method for producing a high-durability composite fabric.

It is an object of the present invention to provide a method of manufacturing a high strength PET fabric or a warp (tricot) fabric by preparing a material comprising a high strength PET fabric or a warp (tricot) fabric, Coating the surface of the prepared material with a non-yellowing high-durability TPE (thermoplastic elastomer) coating solution; A third step of curing the TPE coating solution by heat-treating the material coated with the TPE coating solution; And a fourth step of designing a pattern and a design according to the purpose and type of the coated material, and then stepping the product by high-durability special sewing to form a product. The method for manufacturing a highly durable composite fabric for marine leisure have.

According to the present invention, a coating resin and a coating technique for realizing the above functions by taking into consideration the fact that water repellency, high durability and high weather resistance are required for storage and protection of ships and other leisure facilities in a long and humid marine environment It is possible to develop a high-functional textile material.

FIG. 1 is a flow chart showing a manufacturing process of a highly durable composite fabric for marine leisure according to the present invention, and FIG. 2 is a view illustrating an example of a manufacturing process of a highly durable composite fabric for marine leisure according to the present invention.

As shown in FIGS. 1 and 2, the process for producing a highly durable composite fabric for marine leisure according to the present invention comprises: preparing a material made of a high strength PET fabric or a warp (tricot) fabric; Step S1 of processing; (S2) of coating a surface of the prepared material with a non-yellowing, highly durable TPE (thermoplastic elastomer) coating solution; (S3) of curing the TPE coating liquid by heat-treating the material coated with the TPE coating liquid; (S4) of designing pattern and design according to the purpose and type of the material in which the coating is completed, and making the product by high-durability special sewing.

Step 1 (S1)

In the case of fabrics for marine leisure which are required to be strong and form stability, generally, acrylic and PET fabrics are used, and PVC, PU coating and water repellent coating techniques are used. In the present invention, Coat knitted fabrics are designed and applied for marine leisure applications.

Tricot structure is able to maintain shape stability similar to fabric unlike other knitted fabrics. It can maximize flexibility and ventilation through tissue change, productivity compared to fabric, It is possible to meet various requirements of the present invention.

The flame retardant may be selected from the group consisting of melamine phosphate, melamine polyphosphate, ammonium phosphate, isopropylphenyl diphenyl phosphate (IPPP), triphenyl phosphate (TPP), triethyl phosphate (TEP), resorcinol diphosphate (RDP), tricresyl phosphate (TCP), magnesium dihydroxide (MDH), antimony trioxide, and mixtures thereof.

Step S2 (S2)

A special developed coating method is applied by selecting and modifying environmentally friendly polymer coating resin which is free from the PVC coating method which is generally used for manufacturing marine fabric for marine leisure and has no plasticizer and environmental hormone generation.

INDUSTRIAL APPLICABILITY According to the present invention, a high-performance, high-weatherability marine leisure fabric material having water repellency, UV barrier property and flame retardancy is produced.

The PVC coating method has been replaced by the PU coating and the fluoric coating due to the controversy such as the generation of the environmental hormone used as the plasticizer of the coating resin and the use of the organic solvent. However, since the fluoric coating is expensive, it is used only in the special field.

Conventional PU coatings have been used for manufacturing breathable and waterproof fabrics of clothes and industrial fabrics using an aromatic type coating, but they have disadvantages such as deterioration of long-term durability such as yellowing and harmful controversy (quinone formation) due to sunlight and heat.

The present invention uses TPE. TPE stands for Thermoplastic Elastomer and is a thermoplastic elastomer.

TPE materials are being recycled and environmentally friendly, and their uses and markets are expanding.

TPE is generally composed of a flexible component (a soft segment) that exhibits rubber elasticity and a molecular restraint component (a hard segment) that bridges the bridge of the rubber to prevent plastic deformation.

TPE is a thermoplastic polyolefin (TPAE), a thermoplastic polyamide (TPAE), a thermoplastic polyester (TPA), a thermoplastic polyolefin (TPO), a thermoplastic olefinic elastomer elastomer, TPEE).

Styrene TPE is the most demanded TPE in the world. Compared to other TPEs, they have a soft, bendable nature. Disadvantages are heat, weather and oil resistance. In the case of hydrogenated SEBS, heat resistance and weather resistance are improved.

Olefin TPE (TPO) is widely used in automobile interior and exterior such as bumper and indian panel in order that PP, EPDM, and EPM are the mainstream in quantity, and they are light in weight, excellent in weatherability and ozone resistance have. However, it exhibits relatively low mechanical properties, and has a disadvantage that soft touch is difficult and abrasion resistance is poor.

Amide-based TPE (TPAE) is a polyamide in which the hard segments are nylon 6, 66, 11 and 12, and polyether or polyester is used as a soft segment.

Urethane TPE exhibits excellent performance in abrasion resistance and bending resistance. It also shows soft characteristics without the use of plasticizers and is most widely used as an alternative to PVC in environmental aspects.

Therefore, in order to apply the marine fabric product of the present invention, Urethane TPE having excellent physical properties and excellent abrasion resistance and bending resistance in actual use is applied, and Diisocyanate (-N═C = O)) was selected to produce an urethane-based TPE-coated resin having yellowing resistance.

Polyol (--OH group), which determines the physical properties of the coating, has been prepared by the optimum ratio of polyether system and PC system which is superior in hydrolysis resistance and low temperature bending property.

The present invention relates to a polyolefin (-OH group) which determines the physical properties of a coating for the preparation of a non-yellowing, highly durable TPE coating liquid, an optimum ratio of diisocyanate (-N = C = O) The optimum TPE coating solution is prepared through selection.

20 to 25 parts by weight of a polyol, 30 to 40 parts by weight of a chain extender and 30 to 50 parts by weight of a diisocyanate based on 100 parts by weight of the TPE coating solution.

In the third step (S3), the material coated with the TPE coating solution is heat-treated at a high temperature of about 100 to 120 ° C to cure the TPE coating solution.

Therefore, it is possible to manufacture eco-friendly composite fabric material for high-durability marine leisure by using high-strength PET to replace marine leisure fabric and tricot fabric with PVC non-yellowing high functional coating technology.

In addition, the composite fabric material is applied to the bimini and boat cover of yachts and boats in operation through the design / design of the yacht specialists of the participating companies. It is also possible to commercialize the technology at the same time as feedback.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
