This application claims priority to and the benefit of Korean Patent Application No. 10-2022-0050958 filed on Apr. 25, 2022, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to a breathable fabric, and more particularly, to a breathable fabric in which a weft and a warp of the fabric each include a plurality of strands of yarn, some yarn of the plurality of strands of yarn constituting the weft is convexly woven on one side of the fabric while the rest of the yarn is convexly woven on the other side of the fabric, some yarn of the plurality of strands of yarn constituting the warp is convexly woven on the other side of the fabric while the rest of the yarn is convexly woven on the one side of the fabric, and thus the fabric may be woven to have a three-dimensional effect in a desired shape, the weft and warp are woven in a lattice shape to form a ventilation hole, and thus the fabric can be used as a fabric that requires breathability, and alignment yarn is woven on both outermost sides of the weft and the warp including the plurality of strands of yarn, a state in which the weft and the warp are bundled is maintained, and thus the durability of the fabric increases and the shape of the ventilation hole is maintained.
In general, fabrics are woven by alternating warps and wefts, and fabrics in which ventilation holes are formed according to the purpose and usage are also provided.
A review of the related art related to a breathable fabric shows a “Method of manufacturing highly breathable fabric” disclosed in Korean Patent Registration No. 10-0959509 (Patent Document 1), an “Upper for breathable shoe using jacquard loom and method of manufacturing same” disclosed in Korean Patent Registration No. 10-1582550 (Patent Document 2), and a “Method of manufacturing breathable fabric” disclosed in Korean Patent Registration No. 10-1788692 (Patent Document 3).
Patent Document 1 relates to a method of manufacturing a highly breathable fabric, and more particularly, a method of manufacturing a highly breathable fabric, in which dissolvent yarn is inserted between a weft and a warp while the weft and the warp are spaced apart from each other during weaving, the woven fabric is treated using a scouring solution during scouring and the dissolvent yarn formed between the weft and the warp is thus melted to form a lattice-shaped air hole in the fabric or the woven fabric is treated using water before or after being treated using the scouring solution during the scouring and the dissolvent yarn formed between the weft and the warp is thus melted to form a lattice-shaped air hole in the fabric, and thus air smoothly circulates between an inside and an outside of the fabric, moisture is easily dried, washing power is excellent, and when the fabric is used as an outer skin, the lattice-shaped air hole exhibits a color matching effect that contrasts with a color of a lining.
Patent Document 2 relates to an upper fabric for a breathable shoe and a method of manufacturing the same, in which the upper fabric for the breathable shoe is woven as a warp portion in a longitudinal direction and a weft portion in a width direction cross each other at right angles, a fine longitudinal interval is formed in the longitudinal direction between the warp portions in the longitudinal direction, a fine transverse interval is formed in the width direction between the weft portions in the width direction, a weaving unit is formed at a point at which the warp portion and the weft portion cross each other, and a ventilation hole is formed at a point at which the longitudinal interval in the longitudinal direction and the transverse interval in the width direction cross each other.
In Patent Document 3, during weaving, in a state in which a warp is left empty at regular intervals, a dissolvent yarn is inserted into a weft at regular intervals, and the dissolvent yarn is then removed. Thus, cost can be reduced by reducing the dissolvent yarn and a solvent, operation harmfulness and environmental pollution can be reduced due to the reduction in the solvent, and work efficiency can be improved and cost can be reduced by reducing or simplifying work processes.
The above technical configurations are background art for helping with understanding of the present disclosure, and are not necessarily related art widely known in the technical field to which the present disclosure pertains.
In the case of a fabric having a ventilation hole according to the related art, dissolvent yarn is positioned in the warp and weft at regular intervals, the dissolvent yarn is then dissolved through a post-processing process, and the ventilation hole is formed at an intersection between the warp and the weft at which the dissolvent yarn is positioned. Thus, since a process of removing the dissolvent yarn through a separate post-processing process is required, not only is the processing cumbersome but the environment is also polluted due to use of a solvent in a dissolving process.
Further, in the case of the fabric having a ventilation hole according to the related art, the fabric is woven so that minute gaps are formed at the warp and the weft at regular intervals, and thus the ventilation hole is formed at a point at which the minute gaps intersect each other. However, in the case of the fabric, the tissue density of the minute gaps is sparse, and although an effect of ventilation may thus be expected, the durability of the sparsely woven portion is reduced.
Therefore, this problem needs to be solved.
The present disclosure is directed to providing a breathable fabric in which the weft and warp of the fabric are each provided as a plurality of strands of yarn, some of the plurality of strands of yarn constituting the weft are convexly woven on one side of the fabric and the others are convexly woven on the other side of the fabric, some of the plurality of strands of yarn constituting the warp are convexly woven on other side of the fabric and the others are convexly woven on the one side of the fabric, and thus the fabric is woven to have a three-dimensional effect in a desired shape, thereby implementing excellent aesthetics.

The present disclosure is also directed to providing a breathable fabric in which, as alignment yarn is woven on outermost sides of each of the weft and the warp provided as a plurality of strands of yarn, a state in which each strand of the weft and each strand of the weft are bundled is maintained, and thus the durability of the fabric increases and the shape of the ventilation hole is maintained.

In particular, the ventilation hole 20 has an inner edge formed by the second one side alignment warp 115 and the first other side alignment warp 124 adjacent to each other and the second one side alignment weft 215 and the other side alignment warp 124 adjacent to each other.
Meanwhile, the first one side warp 111, the second one side warp 112, the third one side warp 113, the first one side alignment warp 114, and the second one side alignment warp 115 may have the same thickness or different thicknesses [deniers].
Further, the first other side warp 121, the second other side warp 122, the third other side warp 123, the first other side alignment warp 124, and the second other side alignment warp 125 may have the same thickness or different thicknesses [deniers].
Further, the first one side weft 211, the second one side weft 212, the third one side weft 213, the first one side alignment weft 214, and the second one side alignment weft 215 may have the same thickness or different thicknesses [deniers].
In addition, the first other side weft 221, the second other side weft 222, the third other side weft 223, the first other side alignment weft 224, and the second other side alignment weft 225 may have the same thickness or different thicknesses [deniers].
In the present disclosure, it is illustrated that the first one side warp 111, the second one side warp 112, the third one side warp 113, the first other side warp 121, the second other side warp 122, the third other side warp 123, the first one side weft 211, the second one side weft 212, the third one side weft 213, the first other side weft 221, the second other side weft 222, and the third other side weft 223 have the same thickness or similar thicknesses.
Further, it is illustrated that the first one side alignment warp 114, the second one side alignment warp 115, the first other side alignment warp 124, the second other side alignment warp 125, the first one side alignment weft 214, the second one side alignment weft 215, the first other side alignment weft 224, and the second other side alignment weft 225 have smaller thicknesses than the first one side warp 111.
In this case, the first one side alignment warp 114, the second one side alignment warp 115, the first other side alignment warp 124, the second other side alignment warp 125, the first one side alignment weft 214, the second one side alignment weft 215, the first other side alignment weft 224, and the second other side alignment weft 225 may be made of a transparent material or a material having a different color from that of the first one side warp 111 to maximize aesthetics of the breathable fabric 10.
Meanwhile, the first one side warp 111, the second one side warp 112, the third one side warp 113, the first one side alignment warp 114, and the second one side alignment warp 115 may be made of the same material or different materials.
Further, the first other side warp 121, the second other side warp 122, the third other side warp 123, the first other side alignment warp 124, and the second other side alignment warp 125 may be made of the same material or different materials.
Further, the first one side weft 211, the second one side weft 212, the third one side weft 213, the first one side alignment weft 214, and the second one side alignment weft 215 may be made of the same material or different materials.
In addition, the first other side weft 221, the second other side weft 222, the third other side weft 223, the first other side alignment weft 224, and the second other side alignment weft 225 may be made of the same material or different materials.
Of course, various materials and various shape may be applied to the first one side warp 111, the second one side warp 112, the third one side warp 113, the first other side warp 121, the second other side warp 122, the third other side warp 123, the first one side weft 211, the second one side weft 212, the third one side weft 213, the first other side weft 221, the second other side weft 222, and the third other side weft 223.
Likewise, various materials and various shapes may be applied to the first one side alignment warp 114, the second one side alignment warp 115, the first other side alignment warp 124, the second other side alignment warp 125, the first one side alignment weft 214, the second one side alignment weft 215, the first other side alignment weft 224, and the second other side alignment weft 225.
As an example, monofilament yarn may be applied to the first one side alignment warp 114, the second one side alignment warp 115, the first other side alignment warp 124, the second other side alignment warp 125, the first one side alignment weft 214, the second one side alignment weft 215, the first other side alignment weft 224, and the second other side alignment weft 225.
As an example, draw textured yarn (DTY) may be applied to the first one side warp 111, the second one side warp 112, the third one side warp 113, the first other side warp 121, the second other side warp 122, the third other side warp 123, the first one side weft 211, the second one side weft 212, the third one side weft 213, the first other side weft 221, the second other side weft 222, and the third other side weft 223.
In this case, the DTY is processed yarn processed by false-twisting filament yarn and then applying heat to the filament yarn to fix the filament yarn and the processed yarn is bulky and has elasticity and stiffness.
Here, false twisting is a method in which the filament yarn is twisted and is then detwisted, that is, the twisting and the detwisting are simultaneously performed in a false-twist device to provide a crimp.
Further, the monofilament yarn is yarn made of a fiber having an infinite length and is single yarn made of one type of fiber selected from the group consisting of silk fibers such as a natural fiber and a rayon fiber, cupra fibers such as a regenerated fiber, and synthetic fibers such as polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, polyamide fibers, polyurethane fibers, and polyvinylidene chloride fibers.
In particular, when the DTY obtained by processing the filament yarn is not used and raw yarn is used as it is, the raw yarn is not suitable for a role of a rear layer applied to artificial leather due to degradation of elasticity, touch sense, versatility, and high quality, marketability is also degraded, and thus the DTY obtained by processing the filament yarn may be used.
The DTY may be dope dyed yarn or may be dyed by a post-dyeing method.
Further, when a twisting angle θ of the DTY is in a range of 40° to 55° or 45° to 50°, the productivity is excellent.
In addition, a linear mass density D of the DTY may be in a range of 60 to 90 deniers or 70 to 85 deniers. When the linear mass density D is less than this range, the thickness is too low, and thus the strength may decrease. When the linear mass density D is greater than this range, cost increases and the rear layer becomes too heavy, and thus the elongation as artificial leather for interior materials of commercial vehicles may decrease. Thus, the DTY may have a thickness within this range.
