Description

TECHNICAL FIELD [0001] The present invention relates to a polypropylene-based fabric,

The present invention relates to a polypropylene awning fabric and a method of manufacturing the same, and more particularly, to an awning fabric of a polypropylene material which is manufactured by manufacturing a seamless yarn of only polypropylene, .

The awning fabric has been used for a long time as a fabric for an outdoor car, a curtain, and a parasol which is considering the surrounding atmosphere while shielding light from the United States and Europe. Recently, it has been used in restaurants and restaurants It is installed on the outer front of the building to block the sunlight inside the building and prevent rain and snow. It is designed to display various unique colors and structures, thereby giving a visual differentiation effect to other companies, In order to serve as an advertisement effect to be transmitted to the city.

Since the fabric is installed mainly outside the outer building, it should be free from discoloration or discoloration due to sunlight for a long period of time, for at least 5 years, have excellent quality and weatherability, have a certain hardness for natural bending as desired, .

At first, fuzzy fabric made of tough natural hemp fiber was applied, but in this case, it is heavy and difficult to give various colors, and also has a disadvantage that it is discolored and discolored by daylight, and weatherability and durability are poor Which was replaced by synthetic fibers.

In addition, unlike the prior art which was used for the purpose of simply shielding the sunlight as described above, a function as a trademark indicating the quality of goods or services provided by a shop provided with a curtain or a car which is formed of a corrugated fabric is further required And the acrylic fiber which is mainly made of staple yarn is easily used as a garment fabric in order to create a luxurious image among the synthetic fibers. .

When manufactured from acrylic fiber, the weight is lighter than natural woolen fabric, has excellent strength, is not monotonous in appearance, is excellent in touch and drape, and can produce a luxurious atmosphere. And it has been widely applied until now. However, in the case of the corrugated fiber fabric made of acrylic fiber, the unit price is high and it has been limited to widely spread.

Next, although a problem of the acrylic fiber is solved to some extent, the use of a polyester fiber-based roughness fabric has been used. However, the generation of harmful environmental substances is serious in the manufacturing process, and development of a more environmentally friendly material is required.

Hereinafter, the present invention will be described in detail.

The inventors of the present invention have conducted studies to reduce the generation of environmental risk factors that are problematic in the production of an ear fabric using polyester fiber, and as a result, it is possible to manufacture a yarn using a polypropylene resin, Waterproof and flame retardant, and is environmentally friendly.

Accordingly, the present invention provides a method for producing a polypropylene awning fabric, which is manufactured by impregnating and drying a fabric woven with a polypropylene base yarn into a flame retardant and water repellent resin.

The polypropylene original yarn preferably contains a nano-coated loess powder, and the content of the nano-coated loess powder in the polypropylene raw yarn may be 1 to 5 wt%.

The polypropylene base yarn may be prepared by mixing, extruding and spinning a urethane resin for promoting bonding of the two components in addition to the polypropylene resin and the silver halide powder.

As a preferred embodiment, the process for producing the polypropylene raw material of the present invention is as follows.

First, when alcohol is added to the colloid solution, silver nitrate is consumed when silver is dissolved by adding nitric acid while heating 300 g of silver nitrate in a dissolution tank. Furthermore, 100 g of the first stones were dissolved in 100 ml of hydrochloric acid, and the resultant solution was stirred and stirred in the silver solution. To adjust the pH of the silver solution to neutral, 150 g of zinc oxide was dissolved in 500 g of a caustic soda solution (pH 13), and while the silver solution was synthesized with the silver solution, the solution was brought to pH 7.5 to evaporate water to obtain silver salt of the powder. 150 g of the silver salt was dissolved in 500 ml of ethyl alcohol and 350 ml of isopropyl alcohol and decomposed, and 3 g of bromosoda was added thereto. The silver solution was dissolved in a glass beaker and then exposed to the sun for 3 hours. After 24 hours, To produce an alcohol type silver nano colloid.

Next, 100 g of powder ground with 3,000 mesh of loess is quantitatively mixed, and then 100 g of tourmaline 2,000 mesh powder is mixed to prepare 200 g of loess composition.

Next, 200 g of the loess composition was weighed in 200 g of the silver solution of the first step into a stencil mixer, and the silver loess composition was soaked in water to completely blow off water while heating at about 50 ° C and pulverized again to prepare a nano-coated loess powder .

Finally, 50 g of the silver-coated yellow ocher powder of the third step and 100 g of the urethane resin are mixed with 1,000 g of the polypropylene resin, and the resulting mixture is extruded and spun to produce a polypropylene raw yarn.

The polypropylene original yarn produced as described above is produced by weaving a weft yarn and a warp yarn in a denier of 300 to 3,000.

The manufactured fabric is impregnated with a flame retardant and water repellent resin and dried to improve the flame resistance and water repellency of the fabric.

A preferred flame-retardant and water-repellent resin treatment method is as follows.

First, the prepared corrugated fabric was impregnated with a flame retardant and water-repellent resin mixed with 5 to 25% by weight of a phosphorus-based flame retardant, 5 to 10% by weight of a fluorine-based water repellent-containing copolymer, and 3 to 10% by weight of an acrylic resin, And allowed to pass through a mangle with an air pressure of 3 to 7 kg to allow water to be removed.

The flame-retardant and water-repellent functional resin is in the form of a transparent liquid. In forming the flame-retardant and water-repellent functional resin, the phosphorous flame retardant is responsible for flame retarding function. When the phosphorus flame retardant is less than 5% by weight, the flame retarding effect is poor. When the phosphorus flame retardant is more than 25% by weight, there is no economical efficiency.

If the content of the fluorine-based water-repellent-containing copolymer is less than 5% by weight in the fluorine-based water-repellent-containing copolymer at 5 to 10% by weight, the water repellency becomes poor.

The composition ratio of the acrylic resin (3 to 10% by weight) is for imparting a stiff feeling inherent to the shading film or the tent paper.

The fabric having the flame-repellent and water-repellent function is dried in the dryer at a temperature of 140 to 230 ° C, more preferably 170 to 230 ° C for 30 to 250 seconds, . The drying condition in this dryer is to dry the fabric and to shrink the fabric so that the yarn is densely formed so that the subsequent coating process can be smoothly performed.

After the drying process in the dryer is completed, it is preferable to apply 1 to 10 times of 0.1 to 1.5 mm thickness on one surface of the fabric including flame-retardant and water-repellent function by knife coating method using a waterproof and flame-retardant resin. The waterproof and flame retardant resin of the present invention used in the knife coating is composed of 70 to 90% by weight of polyurethane and 10 to 30% by weight of phosphorus flame retardant as a transparent liquid. Among the components of the waterproof and flame-retardant resin, the polyurethane is a viscous liquid material having a waterproof function, and the phosphorous flame retardant is a transparent liquid phase, and its composition ratio can realize waterproofing and flame retarding effect at the same time. It is.

When a transparent waterproof and flame resistant resin layer is formed on a fabric including a flame-retardant and water-repellent function by a knife coating method, and then dried at a temperature of 120 to 200 ° C for 30 to 250 seconds in a dryer, the fabric of the present invention is completed.

As described above, the present invention can solve the drawbacks of the coating surface that occurs when the flame-retardant and water-proofing functions are limited to the thin and monochrome-oriented fabric using the bromine-based flame retardant added with the pigment as in the prior art, Especially, when the fabric is thick, it improves the difficulties in flame-retarding and waterproofing work. Also, since the flameproofing and water-repellent function is clear due to the use of phosphorous flame retardant agent, and the waterproof and flame-resistant resin layer becomes transparent, The various colors of the fabric can be represented as they are.

Accordingly, the present invention provides a polypropylene awning fabric produced by the manufacturing method of the present invention.

The fabric of the present invention can be fabricated from a polypropylene material to produce a fabric that is environmentally friendly and has excellent flame retardancy and water repellency.
