In addition, according to an example embodiment of the present invention, the textile fabric has the pattern which when the pattern makes contact with moisture, such as snow, rain, water and sweat, so that not only aesthetics can be improved, but a publicity effect can also be obtained.
Hereinafter, the invention will be explained in detail with reference to the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein and shown in accompanying drawings. The same reference numerals will be used to refer to the same or like parts.
A textile fabric according to an embodiment of the present invention includes a wettable portion and a non-wettable portion. When the textile fabric is in contact with moisture, a pattern is formed on a surface thereof due to a contrast of a wet portion and a non-wet portion. Here, the wet portion may be the textile fabric itself, and a water-repellent mixed solution may be coated on the non-wet portion. In this case, the wet portion may be made to form a specific pattern, or the non-wet portion may be made to form a specific pattern. Hereinafter, the description will be made by taking as an example that the non-wet portion forms the specific pattern.
According to the embodiments of the present invention, a predetermined pattern of the textile fabric printed on a surface of the textile fabric appears when water is sprayed, so that a portion of the textile fabric that forms a particular shape is waterproof, and this can be achieved by forming a water repellent layer at a specific portion of the surface of the textile fabric.
The water repellent layer may be formed on a textile fabric in various methods. For example, a water repellent mixture may be applied to a pressing member having an embossed pattern, and the surface of the textile fabric may be pressed by the pressing member so that the embossed pattern is printed on the surface of the textile fabric. In this case, the pressing member can be applied without any particular limitations as far as it can press and print on the textile fabric. In the embodiment of the present invention, a roller is used.
For example, when one side of a textile fabric is pressed by the roller, the embossed pattern of the roller is printed on the surface of the textile fabric. The embossed pattern protruding from a surface of the roller is coated with a water repellent mixed solution. Therefore, the water repellent mixed solution is applied to the textile fabric together with the pattern printing by the roller.
As described above, when the textile fabric is wet with water, the water penetrates into the textile fabric, but where the water repellent mixed solution is coated, water repellent mixed solution prevents the moisture from penetrating into the textile fabric.
Accordingly, the pattern on the textile fabric appears because a portion of the textile fabric to which the water repellent mixed solution is not applied and a portion of the textile fabric to which the water repelling mixed solution is applied have different brightness. That is, as wet portion of the textile fabric becomes a dark shade and the portion where the water repellent mixed solution is applied is compared with the wet pattern portion, the pattern clearly appears on the surface of the textile fabric apparently.
Referring to
The method of manufacturing the textile fabric according to an example embodiment of the present invention coating hygroscopic softener (S100), printing water-repellent mixed solution (S200), drying (S300), and waterproof treatment (S400). Although the step of coating hygroscopic softener (S100), and printing water-repellent mixed solution (S200) can be omitted, the embodiment of the present invention will be described as including these two processes.
Coating Hygroscopic Softener (S100)
The hygroscopic softener is to absorb sweat and moisture quickly. When the hygroscopic softener on a textile fabric 10, even if a small amount of water makes contact with the textile fabric 10, a portion on which the water repellent mixed solution is not coated is well wetted. Accordingly, a pattern can be clearly seen as a whole.
For application of the hygroscopic softener, for example, as shown in
Thereafter, the textile fabric 10 coated with the hygroscopic softener is dried by passing through a drying chamber 40 having an internal temperature condition of 160° C. to 180° C. by a heater or hot air. If the drying temperature is less than 160° C., the drying time may increase, and productivity may be deteriorated. If the drying temperature is higher than 180° C., the textile fabric 10 may be thermally deformed.
After the application of the hygroscopic softener and the drying process, the textile fabric is wound in a form of a roll and transferred to a next step.
Printing a Water-Repellent Mixed Solution (S200)
After the application of the hygroscopic softener and the drying process, the textile fabric 10 is transported to the opposite side at a speed of 20 yd/min to 40 yd/min, and rolled. In this process, the roller 50 rotates to press one surface of the textile fabric 10, and a pattern of the predetermined pattern is repeatedly printed along the length of the textile fabric 10.
A predetermined pattern is embossed on the surface of the roller 50, and a water-repellent mixed solution is applied to the embossed pattern. Accordingly, the pattern of the surface of the roller 50 is correspondingly printed to the textile fabric 10 while one surface of the textile fabric 10 is pressed by the roller 50. The roller 50 can press the textile fabric 10 at a temperature of 110° C. to 130° C.
In this case, if the moving speed of the textile fabric 10 is less than 20 yd/min, productivity may be deteriorated, and if the moving speed of the textile fabric 10 exceeds 40 yd/min, printing quality may be deteriorated. In addition, if the temperature is lower than 110° C. when the roller 50 is pressed, printing may not be performed uniformly, and if the temperature is higher than 130° C., the textile fabric 10 may be thermally deformed.
In addition, as described above, a water-repellent mixed solution is coated on a protrusion 51 of the surface of the roller 50 which forms the pattern, and a water-repellent mixed solution is applied to the textile fabric 10 corresponding to the pattern of the protrusion 51 during the pattern printing process.
Here, the water-repellent mixed solution is a mixture of 45 wt % to 55 wt % of water-repellent agent, 3 wt % to 7 wt % of fixing agent, 1 wt % to 3 wt % of silicone softer, 1 wt % to 5 wt % of thickener, and 30 wt % to 50 wt % of water.
In this case, the water-repellent agent may be, for example, a solution of zirconium acetate. If the amount is less than 45 wt %, water repellency effect may be deteriorated. If the amount exceeds 55 wt %, effect according to the amount of injection may be insignificant and the economical efficiency may be lowered.
The fixing agent may be composed of, for example, a polyurethane solution for a fiber. If the amount is less than 3 wt %, fixing effect may be deteriorated. If the amount is more than 7 wt %, effect according to the amount of injection may be insignificant and the economical efficiency may be lowered.
The silicone softer is for imparting elasticity and flexibility to the textile fabric 10. If the amount is less than 1 wt %, softening effect may be deteriorated. If the amount is more than 3 wt %, effect according to the amount of injection may be insignificant and the economical efficiency may be lowered.
The thickener is added to improve efficiency of the padding operation of the textile fabric 10. If the amount is less than 1 wt %, effect may be deteriorated. If the amount is more than 5 wt %, effect according to the amount of injection may be insignificant and the economical efficiency may be lowered.
The water is used for dilution of the mixed solution, and 30 wt % to 50 wt % is added in consideration of the water repellency effect and economical efficiency.
As described above, the water-repellent mixed solution is coated to the protrusion 51 of the roller 50 and is applied in a form of a pattern on one side of the textile fabric 10 when the textile fabric 10 is pressed. When the textile fabric 10 is wetted, the portion where the water-repelling mixed solution is applied is prevented from penetration of water.
Accordingly, the water-repellent mixed solution applied to the textile fabric 10 in the form of the pattern is not normally visible, but when the textile fabric 10 is wetted with water, the pattern on the surface of the textile fabric 10 is appears by contrasting shade with wetted portion of the textile fabric 10.
In addition, after printing the pattern to which the water-repellent mixed solution is applied by the roller 50, the textile fabric 10 is wound into a roll form and transferred to a next step.
In addition, although the pattern is printed on the textile fabric 10 by the roller 50 in this embodiment, it is possible that the textile fabric 10 may be pressed by a pressing member such as a press to print the pattern on the textile fabric 10.
Drying (S300):
The textile fabric 10 on which the pattern is printed with the water-repellent mixed solution is conveyed to the opposite side at a speed of 40 to 60 yd/min and wound in a form of a roll again. While the textile fabric 10 is wound, drying is performed by passing through a tenter machine 60 in which an atmospheric temperature of 160° C. to 180° C.
In this case, if moving speed of the textile fabric 10 is less than 40 yd/min, the textile fabric 10 may be thermally deformed. If the moving speed of the textile fabric 10 exceeds 60 yd/min, uniformity of drying quality may be lowered.
The textile fabric 10 may be dried by hot air sprayed through inside of the tenter machine 60. At this time, a heat setting step and a shrinking step by heat treatment may be performed together. The textile fabric 10 which is wound into a roll and transferred to a next step.
Waterproof Treatment (S400):
In a step of waterproofing treatment, polyurethane is coated on the other side of the textile fabric 10, that is, the opposite side of the side on which the water-repellent mixed solution is printed.
In this case, the textile fabric 10 after drying is reversely transferred by 40 yd/min to 60 yd/min and the polyurethane is coated on the other side of the textile fabric 10 at a temperature of 120° C. to 140° C. so that the textile fabric 10 is wound again in a form of a roll. If moving speed of the textile fabric 10 is less than 40 yd/min, productivity may be degraded. If the moving speed of the textile fabric 10 exceeds 60 yd/min, it may be difficult to obtain a uniform coating layer.
Here, the polyurethane coated on the other side of the textile fabric 10 may perform a function of preventing passage of moisture. Accordingly, the pattern may appear on the surface of the textile fabric 10 by penetration of moisture. However, a body wrapped by a textile fabric or inside of the textile product may be prevented from being wetted by the polyurethane coating layer.
The textile fabric 10 according to the embodiment of the present invention may be applied to various textile products. Especially, the textile fabric 10 may be applied to a rain cover of an outdoor backpack, an umbrella, climbing clothes, a cap, etc. The textile fabric 10 may be applied to a variety of outdoor items, such as aquatic clothing, such as swimwear, which are mainly used in water. As an example, a leisure cap 100 to be worn when exercising golf, tennis, or outdoor activities such as jogging or walking can also be manufactured using the textile fabric 10 according to the embodiment of the present invention.
In this case, the leisure cap 100 includes a crown 110 having a hollow hemisphere shape to cover a head and a visor 120 extending outward from a lower side of the crown 110 and covering the sunlight. A sweat absorbing band 130 may be interposed between the visor 120 and the crown 110 with a predetermined width. The sweat absorbing band 130 is normally folded in an inner side of the crown 110 to absorb sweat of a forehead and may be exposed to the outside of the crown 110 if necessary.
Comparing
In a case of the embodiment shown in
In addition, as described above, according to the textile fabric according to the embodiment of the present invention, the pattern divided into two regions (bright region and dark region) by contrast to shade of wetted region and non-wet region thereon. In this case, by varying the degree of water absorption in the textile fabric 10, a pattern divided into three or more regions may be embodied. And, this may be achieved by varying the application amount of the water-repellent mixed solution to the textile fabric 10 according to the regions of the pattern.
A roller 50′ for manufacturing a textile fabric according to an embodiment of the present invention has a pattern which is embossed on a surface of the roller 50′. The patterns of the rollers 50′ include at least two regions in which coating liquid per unit area, that is, application amount of water-repellent mixed solution per unit area is different from each other.
As an example, a surface of a first region A may be formed as a smooth surface, and a plurality of protrusions 52 may be formed on a surface of a second region B by a predetermined distance. Here, end of the protrusion 52 in the second region B is formed at the same height as the surface of the first region A.
When the water-repellent mixed solution is coated on the roller 50′, the water-repellent mixed solution is applied only to a surface of the embossed pattern, so that the water-repellent mixed solution is coated entire of the surface of the first regions A, and the water-repellent mixed solution is coated only on the end of the protrusions 52 in the second region B. Accordingly, application amount of the water-repellent mixed solution per unit area of the first region A becomes larger than application amount of the water-repellent mixed solution per unit area of the second region B.
When the pattern is printed on the surface of the textile fabric 10 by using the roller 50′, the water-repellent mixed solution is uniformly printed on the entire area in a portion of the pattern corresponding to the first region A of the roller 50′, and the water-repellent mixed solution is printed on a portion of the pattern corresponding to the second region B of the roller 50′ with a smaller amount of the water-repelling mixed solution than that of the first region A.
When the textile fabric 10 on which the water-repelling mixed solution is printed by pressing the roller 50′ becomes wet with water, the portion of the pattern corresponding to the first region A is not wetted with water and appears bright because the water-repelling mixed solution is entirely coated. Since the portion of the pattern corresponding to the second region B is not formed entirely of the water-repelling mixed solution, but a plurality of water-repellent mixed solutions are spaced apart from each other by the predetermined distance, portions between the water-repellent mixed solutions becomes wet with water. Accordingly, the portion of pattern corresponding to the second region B is somewhat darker than the portion of the pattern corresponding to the first region A as a whole. And, the portion of the textile fabric 10 where the pattern is not printed at all is completely wetted with water and appears darker than the second region B.
That is, the rollers for manufacturing the textile fabric according to the embodiment of the present invention may show a pattern which has a portion which is not wetted with water (the portion corresponding to the first region A), a portion slightly wetted with water (the portion corresponding to the second region B) and a portion fully wetted with water (where the pattern is not printed) can be manufactured in which the pattern divided into three regions.
In addition, although not shown in figures, density of the protrusions 52 per unit area may be different from each other depending on regions of the pattern, so that a plurality of regions having different amounts of the water-repellent mixed solution per unit area may be formed. For example, a plurality of the protrusions 52 may be formed in the first region A and the second region B such that a narrow gap between the protrusions in the first region A and a wide gap between the protrusions 52 in the second region B. Accordingly, a portion of the textile fabric corresponding to the second region B is wetted with water more than a portion corresponding to the first region A, so that shadow contrast may be formed between the first area A and the second area B.
Although the embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims.
The present invention provides a textile fabric on which a predetermined pattern appears when the fiber fabric makes contact with moisture such as rain, snow, sweat and the like, and a method of manufacturing the same.
The present invention also provides a textile product which a pattern is appeared thereon when rain, snow, or sweating. As a result, not only the aesthetics of the textile product can be improved, but also a promotional effect can be obtained.
