Description

Fiber composition with hydrophobic substance and its application

The present invention relates to a textile yarn, in particular to a fiber composition having a hydrophobic substance and its application in the field of textile fabrics and gauze nets.

The atmosphere on the earth's surface is the source of oxygen that humans need to breathe, while the exhaust gas and dust discharged by factories, the exhaust gas and dust generated by people's daily lives, and the exhaust gas and dust generated by vehicles will cause air pollution. Suspended particles, dust and dust in the air not only pollute the home living environment, but also affect the health of people's respiratory system and the mechanism of plant respiration.

Generally, the window screen and door screen used can mainly prevent mosquitoes from entering the room and also have ventilation effect. However, the mesh size of the screen used cannot prevent sand and dust from entering the home living environment with the air, and of course it cannot prevent rainwater from entering the room on rainy days.

In order to have a clean living environment at home, some manufacturers have developed a method of laying an electrostatic nanofilm layer on the inner and outer surfaces of a mesh body woven from metal yarns to filter out suspended particles in the environment and have the functions of splashproofing and ventilation. However, the electrostatic nanofilm layer on the surface of the mesh body is not effective for a long time after being exposed to wind and sun, and its production is also difficult. The cost is high. Another industry has developed a polymer water-absorbing body composed of multiple screens and sodium polyacrylate coated on the outer layer of each screen. The high-molecular water-absorbing body uses its property of swelling when exposed to water and shrinking without water to open and close the holes between the screens to achieve waterproof and ventilated effects. However, sodium polyacrylate is not resistant to high temperatures and cannot withstand sunlight, which is its disadvantage.

The main purpose of the present invention is to provide a fiber composition with hydrophobic material and its application, which has the functions of blocking dust in the air, blocking water and ventilating at low cost.

A secondary object of the present invention is to provide a fiber composition having a hydrophobic substance and its application, which has a better service life.

Another object of the present invention is to provide a fiber composition having a hydrophobic substance and its application, which can be applied to the fields of yarn nets and agricultural planting.

Therefore, in order to achieve the above-mentioned purpose, the present invention provides a fiber composition with hydrophobic substances, which at least includes a non-metallic yarn and a water-repellent material; the non-metallic yarn has an appropriate length and weight and its outer side is at least coated with a water-repellent material or mixed with a water-repellent material to form a fiber composition, and the weight of the non-metallic yarn is a single filament yarn of no more than 300 deniers; the present invention further adopts a plurality of fiber compositions arranged at intervals in the left-right direction and a plurality of fiber compositions arranged at intervals in the up-down direction to be interwoven in a warp-weft manner to form a textile fabric with an appropriate mesh, and the textile fabric is further coated with an adhesive and a water-repellent material and applied to the yarn net to achieve the effect of waterproofing and preventing air pollution.

Hereinafter, several preferred embodiments of the present invention are described in detail with reference to the accompanying drawings:

Please refer to FIG. 1 and FIG. 2 , the fiber composition with hydrophobic material disclosed in the present invention at least includes a non-metallic yarn 12 and a water-repellent material 14.

The non-metallic yarn 12, such as a polyester fiber, has a suitable length and weight, and its weight is a monofilament yarn of no more than 300 denier.

The non-metallic yarn 12 can be mixed with a plurality of dyeing powders or masterbatches during the spinning process to form a colored monofilament yarn. The colors of the plurality of dyeing powders or masterbatches can be set to black, purple or green. If the non-metallic yarn 12 of polyester fiber is not mixed with a plurality of dyeing powders or masterbatches during the spinning process, the formed monofilament yarn is light-transmissive.

The water-repellent material 14 is coated on the outer side of the non-metallic yarn 12 (as shown in FIG. 1 and FIG. 2 ) or the non-metallic yarn 12 can be mixed with the water-repellent material 14 during the drawing process (as shown in FIG. 3 ) to form a fiber composition, so that the fiber composition has a water-repellent effect and is also used to achieve the effect of being resistant to sunlight, high temperature and water washing to increase the service life. In the coating process, water, perfluoroalkyl ethyl acrylate copolymer and dipropylene glycol methyl ether are used. ether) is mixed and soaked by the non-metallic yarn 12, so that the water repellent of the perfluoroalkyl ethyl acrylate copolymer is coated on the outside of the non-metallic yarn 12. The perfluoroalkyl ethyl acrylate copolymer can be obtained through commercial activities. Of course, there are other types of water repellents that can be obtained through commercial activities and also have the effect of repelling water, and the perfluoroalkyl ethyl acrylate copolymer has a better effect.

Please refer to FIG. 4 . The present invention uses a plurality of fiber compositions arranged at intervals in the left-right direction and a plurality of fiber compositions arranged at intervals in the up-down direction to weave in a warp-weft manner to form a woven fabric 10 with a suitable mesh. The woven fabric 10 with a mesh can be produced using a weaving machine, wherein the mesh of the woven fabric 10 can be set to 2300-3600 meshes.

Due to the durability of the textile 10 and the mesh size of 2300-3600, it can effectively prevent the passage of suspended particles, dust or sand in the air, while maintaining an air circulation effect of about 50%. Therefore, using the textile 10 as a shield for agricultural plants can effectively prevent air pollution on leaves and flowers and fruits while maintaining an air circulation effect. Using the textile 10 as a gauze net in the construction industry can effectively prevent air pollution indoors while maintaining an air circulation effect.

Please refer to Figures 5 and 6. The mesh woven fabric 10 further includes a first coating layer 16 such as an adhesive. The first coating layer 16 is applied to one side of the mesh woven fabric 10 (as shown in Figure 4), two corresponding sides of the mesh woven fabric 10 (as shown in Figure 5) or the surface of each of the fiber compositions by rolling, heating and drying, so that the mesh woven fabric 10 can be stiff without sagging and maintain its interwoven structure, so as to have better freedom and enhance water repellency in subsequent use. The adhesive of the first coating layer 16 can be ethyl acetate.

Please refer to Figures 7 and 8. The mesh woven fabric 10 further includes a second coating layer 18 such as a water repellent. The second coating layer 18 is applied to the surface of the first coating layer 16 by rolling, heating and drying, so that the present invention can further enhance the water repellent effect. When it is applied to the screen net and the windows are not closed and it rains, rainwater will hardly adhere to the screen net, so there is no need to worry about rainwater seeping into the room. In addition, dust attached to the screen net can be easily washed with water or taken away by rainwater. Among them, the second coating layer 18 has the same components as the basic coating layer 14, so that the perfluoroalkyl ethyl acrylate copolymer is coated on the surface of the first coating layer 16.

The meshed textile fabric 10 disclosed in the present invention may not be provided with the first covering layer 16 and the second covering layer 18 at the same time, and the present invention still has the effect of repelling water.

The fiber composition of the present invention is formed by using a single-filament non-metallic yarn 12 of a high molecular polymer as a base material and coating the outer side with a layer of water repellent. The fiber composition has the characteristics of anti-ultraviolet rays and weather resistance that is not easy to fade, thus solving the problem that sodium polyacrylate is not resistant to high temperatures and cannot withstand sunlight and high cost of metal yarn.

The non-metallic yarn 12 of the present invention is formed by a process of mixing the water-repellent material 14 during yarn drawing, and its effect is better than the structure in which the water-repellent material 14 is coated on the outside of the non-metallic yarn 12.
