Description

Technical Field

[0001] The invention relates to a yarn of a textile, in particular to a fiber with multifilament and its application in textile fabrics, curtains and gauze nets. Background Art

[0002] The atmosphere on the earth's surface is the source of oxygen needed for human breathing, 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 transportation will cause air pollution; suspended particles, dust and dust in the air, in addition to polluting the home living environment, will also affect the health of people's respiratory system and the mechanism of plant respiration.

[0003] The commonly used window screens and door screens can mainly block mosquitoes from entering the room and also have a ventilation effect. However, the mesh size of the screens used cannot prevent haze 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.

[0004] In order to have a clean living environment at home, some businesses have developed a method of laying an electrostatic nano film 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 effects of water repellency and ventilation. However, the electrostatic nano film 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 business has developed a polymer water-absorbing body composed of a plurality of screen wires and sodium polyacrylate coated on the outer layer of each screen wire, using its properties of swelling when exposed to water and shrinking without water to open and close the holes between the screen wires to achieve the effects of waterproofing and ventilation. However, the disadvantage of sodium polyacrylate is that it is not resistant to high temperatures and cannot withstand the use of sunlight.

[0005] There is a method developed in the market of coating a woven (plain weave) textile fabric with a coating layer containing a water repellent agent to be used as a screen net, which can effectively prevent the passage of suspended particles, dust or sand in the air, while maintaining the effect of air circulation and water repelling to prevent rainwater from penetrating into the room. However, the spatial structure of the woven (plain weave) method is prone to yarn stripping. When used in building screen nets and assembled in window frames, the coating layer of the water repellent agent can make the textile fabric easily slip out of the window frame, resulting in an uneven screen surface that affects the appearance, and the elasticity and curling of the folding screen cannot be fully utilized. Summary of the invention

[0006] The main purpose of the present invention is to provide a fiber with a multifilament structure and a textile cloth, curtain and gauze having the fiber, which has the functions of blocking dust, suspended particles, dust or sand in the air at a low cost, blocking water, preventing splashing water, preventing rainwater from penetrating into the room and also having the function of ventilation.

[0029] See also Figure 1 , Figure 2 , Figure 3 and Figure 3AThe present invention discloses a composite yarn fiber 12 of a raw filament, which at least includes a plurality of small filaments 22 and a mixed material 14. Each of the small filaments 22, such as a polyester fiber or a polyethylene terephthalate (PET) fiber, has an appropriate length and is arranged in a columnar shape ( Figure 1 ) or arranged adjacently in a spiral manner ( Figure 2 ) to form a yarn of appropriate length, which has approximately 12 to 96 filaments 22 forming a composite yarn with a weight of approximately 20 to 150 deniers or 20 to 600 deniers.

[0030] Please refer to Figure 3 The present invention uses the mixed material 14 to coat the yarn or soak the yarn in the mixed material 14, so that the mixed material 14 is distributed in the gaps between the small filaments 22 and / or coated on the outer peripheral side of the yarn, wherein the mixed material 14 at least includes a nano-fluorine water-repellent material such as a nano-fluorine water-repellent agent of a perfluoroalkylethyl acrylate copolymer and an adhesive material and further includes a flame retardant material, so that the present invention has water-repellent and flame retardant / fireproof effects.

[0031] The water-repellent material can be mixed with water, perfluoroalkylethylacrylate copolymer and dipropylene glycol methyl ether, and the adhesive material such as an adhesive such as ethyl acetate is used to make the mixed material 14 adhere to the yarn; the present invention uses a water-repellent agent of perfluoroalkylethylacrylate copolymer to make the yarn hydrophobic and also to achieve the effects of sun resistance, high temperature resistance, transparency and water washing resistance to increase the service life. Perfluoroalkylethylacrylate copolymer can be obtained through commercial activities. Of course, there are other types of water-repellent agents that can be obtained through commercial activities and also have water-repellent effects, and perfluoroalkylethylacrylate copolymer has a better effect; in addition, the water-repellent agent can use fluorine-free acrylate copolymer to achieve the above-mentioned effects.

[0032] The flame retardant material may be composed of 15 H 31 O9P3 (flame retardant FRC-1) and C9H 20 O6P2 (methylphosphonic acid (5-ethyl-2-methyl-2-oxo-1,3,2-dioxaphosphinane-5-yl) methyl methyl ester) compound.

[0033] Each of the filaments 22 can be mixed with a plurality of dyeing powders or masterbatches during the drawing process, so that the dyeing powders are distributed in the pores of each of the filaments 22 to form a colored monofilament yarn. The color of the dyeing powder or masterbatch can be set to black, purple or green, and the monofilament yarn formed is opaque or not completely translucent. If the filaments 22 of the polyester fiber are not mixed with a plurality of dyeing powders or masterbatches during the drawing process, the monofilament yarn formed is translucent or not completely translucent.

[0034] See also Figure 4 and Figure 5 The present invention uses a plurality of fibers 12 arranged at intervals in the left-right direction or a plurality of fibers 12 arranged at intervals in the up-down direction to form a latitudinal pattern (such as Figure 4 ) or meridional mode (such as Figure 5 ) are knitted in an interwoven manner to form a mesh textile fabric 10, which can be made using a knitting machine, wherein the knitting method adopts hook weaving and the knitted textile fabric in the weft or warp direction has a series of arranged loops, and the knitted textile fabric in the weft or warp direction has the number of loops in the column direction and the row direction, and the mesh is defined as the number of loops in the column direction multiplied by the number of loops in the row direction in an area of ​​1 square inch. The mesh of the knitted mesh textile fabric 10 of the present invention can be set to 500-2000 meshes.

[0035] Due to the durability of the mesh textile fabric 10, the number of loops in the row direction and the mesh size of 500 to 2000, it can effectively prevent the passage of suspended particles, dust or sand particles in the air, while maintaining the effects of air circulation and transparency. Therefore, using the mesh textile fabric 10 as an agricultural plant shield can effectively prevent air pollution on leaves and flowers and fruits while maintaining the effect of air circulation. Using the mesh textile fabric 10 as an anti-haze screen net in the construction industry can effectively prevent air pollution indoors while maintaining the effect of air circulation.

[0036] The knitted mesh textile fabric 10 has better elasticity and is therefore better suited for use as a folded window screen fabric.

[0037] In addition, a knitting method of the mesh textile fabric 10 is that the fibers 12 of 40-60 denier are interwoven in a weft manner on one side of the two corresponding sides of the mesh textile fabric, and the fibers 12 of 130-150 denier are interwoven in a weft manner on the other side. In other words, a circular machine is used to interlock the double-sided weft knitting to form a mesh structure, or a warp knitting machine is used to arrange the two corresponding sides into a mesh structure in a warp knitting manner, so that the two corresponding sides of the mesh textile fabric 10 have a relatively fine side and a rough side, the rough side corresponds to the outdoors and has a better filtering effect, and the fine side corresponds to the indoors and has a light-transmitting effect.

[0038] See also Figure 6 and Figure 7 The mesh textile fabric 10 further comprises a covering layer 16, which comprises at least the aforementioned water-repellent material and adhesive material and further comprises the aforementioned flame-retardant material, so that the present invention further enhances the water-repellent and flame-retardant / fireproof effects. The covering layer 16 is formed by rolling, heating and drying to be coated on one side (such as Figure 6 ), the corresponding two sides of the mesh textile fabric 10 (such as Figure 7 ) or the surface of each of the fibers 12, so that the mesh woven fabric 10 can be stiff and flat without sagging and maintain its interwoven structure, so as to have better freedom in subsequent use, wherein the adhesive of the coating layer 16 can be set to ethyl acetate. Each of the filaments 22 uses polyethylene terephthalate (PET) fiber to have a more stiff and flat effect.

[0039] The present invention further enhances the water-repellent effect through the nano-fluorine water-repellent material of the mixed material 14 and / or the coating layer 16. When applied to the screen net and the window is not closed on a rainy day, rainwater will hardly adhere to the screen net, and there is no need to worry about rainwater seeping into the room. In addition, dust attached to the screen net can be easily washed away with water or carried away by rainwater.

[0040] The flame retardant material of the mixed material 14 and / or the coating layer 16 makes the present invention more flame retardant / fireproof.

[0041] In addition, the mesh woven fabric 10 disclosed in the present invention may not have the mixed material 14, but may have the covering layer 16, so that the fibers 12 can also achieve the effects of water repellency / splash-proof, durability, mildew resistance and flame retardancy / fireproof; in the manufacturing process, the steps of coating the mixed material 14 on the yarn or soaking the yarn in the mixed material 14 can be omitted, and the covering layer 16 is coated on the mesh woven fabric 10 after the yarn is woven to form the mesh woven fabric 10, thereby reducing the production cost.

[0042] The fiber formed by the composite yarn of the raw yarn (Greige) of the polymer as the base material and the composite yarn itself or the outer surface is coated with a resin with bonding effect and a nano-fluorine water-repellent agent. The fiber has the characteristics of anti-ultraviolet and weather resistance that is not easy to fade, and solves the problem that sodium polyacrylate is not resistant to high temperature and cannot withstand sunlight and the high cost of metal yarn.

[0043] The present invention utilizes the surface tension of the water-repellent material of the coating layer 16 to enable the mesh-shaped textile fabric 10 to prevent the passage of haze and thus have a better anti-haze effect.

[0044] The present invention adopts a knitted textile fabric having a loop-hook weaving structure in the row direction, so that the present invention is not prone to yarn stripping. In particular, when the present invention is used in a building window screen and assembled in a window frame, the loop structure of the present invention has a better anti-slip effect and is not easy to slip out of the window frame, thereby having a better assembly freedom.

[0045] The above are preferred embodiments of the present invention and the technical principles used therein. For those skilled in the art, any obvious changes such as equivalent transformations, simple replacements, etc. based on the technical solution of the present invention, without departing from the spirit and scope of the present invention, are within the scope of protection of the present invention.
