Description

Fiber having hydrophobic substance, and textile fabric and gauze having the same

This work is about a textile yarn, specifically a hydrophobic fiber and its application in 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 companies 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 cost is high. Another company has developed a polymer water-absorbing body composed of multiple screen wires and sodium polyacrylate coated on the outer layer of each screen wire, which absorbs water when it comes into contact with water. The expansion and anhydrous contraction properties are used to open and close the holes between the screen lines to achieve waterproof and ventilation effects. However, sodium polyacrylate is not resistant to high temperatures and cannot withstand sunlight, which is its disadvantage.

The main purpose of this invention is to provide a fiber with hydrophobic substance and a textile fabric and a gauze with the fiber, which have the functions of blocking dust in the air, blocking water and ventilating at low cost.

The secondary purpose of the present invention is to provide a fiber having a hydrophobic substance and a woven fabric and a gauze having the fiber, which have a better service life.

Another purpose of the present invention is to provide a fiber having hydrophobic substance and a textile fabric and a gauze net having the fiber, which can be applied to the fields of gauze nets and agricultural planting.

Therefore, in order to achieve the above-mentioned purpose, the present invention provides a fiber having a hydrophobic substance and a textile fabric and a yarn net having the fiber, which at least comprises a non-metallic yarn and a water-repellent material; the non-metallic yarn has an appropriate length and weight and comprises a core material and an outer peripheral surface adjacent to and surrounding the core material, and the outer peripheral surface is at least covered with the water-repellent material or each pore of the core material is distributed with the water-repellent material. A fiber is formed, and the weight of the non-metallic yarn or fiber is a monofilament yarn of not more than 300 deniers; the creation further adopts a plurality of fibers arranged at intervals in the left-right direction, each of the fibers is bent with fiber loops and interlaced with each other to form a textile fabric with a suitable 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.

Below, some preferred embodiments of this invention are listed and further described in detail with diagrams:

Please refer to FIG. 1 and FIG. 2 . The hydrophobic fiber 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 deniers and includes a core material 22 and an outer peripheral surface 24 adjacent to and surrounding the core material 22. In this embodiment, the core material 22 is composed of a single core, but it is not limited to this and can also be composed of multiple cores.

The non-metallic yarn 12 can be mixed with a plurality of dyeing powders or masterbatches during the spinning process, so that each dyeing powder is distributed in each pore 221 of the core material 22 of the non-metallic yarn 12 to form a colored monofilament yarn. For example, if the weight of the monofilament yarn is not more than 300 deniers, the color 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 formed by coating and surrounding the outer peripheral surface 24 of the non-metallic yarn 12 (as shown in FIG. 1 and FIG. 2 ) or the core material 22 of the non-metallic yarn 12 can be mixed with the water-repellent material 14 during the drawing process so that each pore 221 of the core material 22 of the non-metallic yarn 12 is distributed with the water-repellent material 14 (as shown in FIG. 3 ) to form a fiber such as a monofilament yarn with a weight of no more than 300 deniers, so that the fiber 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 invention adopts a plurality of fibers arranged at intervals in the left-right direction. Each of the fibers is bent into fiber loops and interlaced with each other to form a woven fabric 10 with a suitable mesh. More specifically, the invention adopts a warp needle feeding of fibers arranged at intervals in the left-right direction from the weft direction, and sequentially bends them into fiber loops and interlaces with each other to form a woven fabric 10. The yarns in the woven fabric 10 are presented in the weft direction of the weft needle or a plurality of fibers are interlaced in the upper and lower directions. The warp knitting needles bend the straight-arranged fibers into a series of fiber loops, and at the same time, the newly generated fiber loops in each row are sheathed and connected with the old fiber loops generated in the adjacent row to form a weaving method of the textile 10. Since the fibers in the textile 10 are warp knitted in the warp direction, the two are used to form a textile 10 formed by winding a plurality of fibers in a loop manner. The mesh of the textile 10 can be set to 2000~3600 meshes.

Due to the durability of the textile 10 and the mesh size of 2000-3600, 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.

It is worth mentioning that, since the textile fabric 10 of the present invention is achieved by a knitting method, that is, the fibers of the present invention are formed into coils using a weaving needle, and the coils are then strung together, the textile fabric 10 of the present invention not only has good wrinkle resistance and air permeability, but also has better elasticity and stretchability. At the same time, it is not easy to pull out the yarn (i.e., fiber) at the edge of the textile fabric 10. In this way, in response to the installation and use of the winding yarn of the window screen, the fibers of the present invention combined with the knitting method can have a firmer edge than the flat-woven sand net cut by a hot knife, and it is not easy to break off the thread, which can increase the service life; and the textile fabric 10 with better elasticity is also easier to use when it is rolled back.

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 fiber 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 water repellent effect of the invention is further enhanced. When it is applied to the screen net and the windows are not closed and it rains, the rain will hardly adhere to the screen net, so there is no need to worry about rainwater seeping into the room. In addition, the 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.

This invention uses a single-filament non-metallic yarn 12 of a high molecular polymer as the base material and a layer of water-repellent coated on the outside to form a fiber that is UV-resistant and weather-resistant and not easy to fade, solving the problem of sodium polyacrylate being not resistant to high temperatures and sunlight and high-cost metal yarns.

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 a structure in which the water-repellent material 14 is coated on the outside of the non-metallic yarn 12.
