The present invention relates to an irregular striped coating fabric and a method of manufacturing the same, and more specifically, to a three-dimensional striped coating fabric of natural leather feel and streaks of different sizes and shapes are naturally mixed and the surface of the fabric is different. will be.

At present, Korea is recognized as a textile superpower with the best technology in the field of fiber, which cannot be compared with any other country in the world. However, many years ago, domestic and foreign conditions, low-cost exports of textile products are not competitive enough, and export volume is sharply reduced. Therefore, high value-added textile products must be developed. As the level of consciousness is excellent, the aesthetic sense is excellent, so the standard of clothing preference is very demanding and new fashion style is required, so the design of the basic fabric must be newly changed.

In line with this trend, domestic and overseas textile companies are continuously developing special-shaped fabrics to meet the needs of various consumers.

As a representative example, coating fabrics of stripes by natural irregular wrinkles are commercially available, not stripes formed by conventional general knitting or printing, and this special pattern coating fabric is applied to clothing and furniture cover, etc. It is used for many purposes.

Striped coating fabric by such irregular wrinkles gather woven and knitted dough in the width direction, and grip one end by the fixing means, and then use a motor or the like in the longitudinal direction After twisting and braiding a certain length, usually 5-10m in succession, they are sequentially loaded on a steam heat treatment machine and heat treated at a temperature of about 120 ° C to fix wrinkles, defoam, and form wrinkles due to wrinkles. In the coating treatment or before the coating treatment, the paper roller and the iron plated roller additionally pass through the roller to further secure the wrinkles more firmly, and then the coating treatment to form a natural wrinkle stripes.

According to this known method, streaks formed on the fabric were natural, but wrinkles could not be formed on natural fabrics such as cotton or thick fabrics having thick dough.

The present inventors have also been engaged in the textile fabric manufacturing industry for many years, can see the problems in the production of the stripe coated fabric by the known method as described above and solve the disadvantages, and more reliably in the wrinkles than the conventional method By forming irregular stripes, we have devised a way to develop high-quality three-dimensional fabrics with natural texture.

In order to achieve this object, the present inventor has repeated trial and error, and as a result, the coating process, the pressing process, and the friction process are carried out under newly developed special conditions, and thus the material and thickness of the dough treated by mutual synergy of these processes. It can be applied to all doughs regardless of its height, and the whole surface of fabric is scattered with countless stripes of different heights, lengths, directions, and shapes, making the surface of the fabric three-dimensional, durable, morphologically stable, and natural in washing. We developed a new striped coating fabric with a natural leather feel.

In the irregular striped coating fabric according to the present invention, in the manufacturing method of the coating fabric consisting of a coating step of applying the coated dough with a pigment coating solution and a step of drying the coated dough,

Before the coating treatment, twisting the dough in one direction or two or more directions, through the pressing step of pressing the twisted dough at a pressure of 30-200kgf / ㎠ by a pair of plate-like pressure body;

Through the pressurizing process, the dough having bulging wrinkles on the surface thereof is properly decomposed, and then coated and dried with a coating liquid consisting of a pigment, an acrylic resin or a polyurethane resin, or a mixture thereof and other additives;

The coated dough is rubbed by a friction member for 30 minutes to 2 hours to form a crack pattern on the whole of the treated fabric by uneven cracking of the coated fabric, and at the same time, it is manufactured by a friction process that causes a nap to the surface. .

As the irregular striped coating fabric according to the present invention by the above method is twisted through the pressing process, the overlapped dough portion is not coated during the subsequent coating process to maintain the original color of the dough and crack the coated portion by friction, It is a three-dimensional fabric with mixed stripes and cracks and a nap on the surface. The color of the fabric is lightly colored, and the stripes overlapped with wrinkles and the color of the dough are in the vicinity, which gives the two-color effect of the dough color and coating color. can do.

In addition, the irregular striped coating fabric according to the present invention is a variation of the representative method, it can be produced by first coating treatment in the same manner as described above, and then subjected to the pressing process and the friction process as described above. In this case, the coating fabric formed at this time has stripes, crack patterns, and naps, and the stripes are formed in a uniform uniform color tone, and the coating fabrics are formed in a coating fabric having a soft coloring effect by the crack patterns.

As another variation, the irregular striped coating fabric according to the present invention is subjected to the same coating process as described above and then subjected to the same pressing process, and then coated again (second), and then the friction process It may be rough. At this time, as in the above modification, streaks and cracks are mixed, and the hair is inherent on the surface, and at the same time, a coating color of one coating color and two coating colors can be obtained, thereby forming a coating fabric of various patterns. Can be.

If desired, after dissolving after the pressurization process, additionally passing through a roller presser, the overlapped wrinkles may be flat to form a striped coating fabric having almost the same height, and in this case, a clearer stripes may be obtained. The width of the fabric is greatly narrowed.

The raw material forming the irregular striped coating fabric according to the present invention may be a woven fabric or a knitted fabric, and the fabric may be cotton fiber, polyester fiber or cotton fiber and polyester fiber. All fabrics, including blends, can be applied, and processed fabrics, such as suede, as necessary.

Stripes in the present invention are natural stripes of different lengths, directions, thicknesses, etc. as a whole of the fabric, and since the overlapping degree of the strings is different, the height of the fabric surface formed is different across the entire surface to form a three-dimensional fabric.

In addition, when the twisting process is twisting only one width of the dough, the stripe is thin and dense, and alternatively, the two widths of the dough may be twisted and then twisted together to form a stripe. In all cases, different types of stripes can be obtained.

The coating process may be carried out by a known coating method such as a roller coating method or a spray method, and after coating, the dough is dried in a temperature range of approximately 80 ° C. to 130 ° C. for 30 minutes to 1 hour.

If the coating solution is an acrylic resin, the touch of the finished coating is slightly soft, and if it is a polyurethane resin, it is softened, so that it may be appropriately selected from the two resins according to the quality of the final product, and may be mixed.

The friction process is performed by ordinary sand washing by sand or a fine friction member, and friction is imparted when the dough put into the rotary treatment tank collides with each other while the sand and water rotate together, or a tubular shape is formed. When the dough is put in the primeval place of the dough, the dough is rotated under a certain speed, and the dough is rotated, hitting the interior walls of the primeval, and the friction is given by mutual collision of the dough, and the surface produced by the friction process is cracked and At the same time, it is brushed, and a lot of nap, ie, fine hair, is formed on the entire surface, and according to the degree, natural leather or suede atmosphere can be produced.

The coating liquid penetrated between the surface tissues of the dough by the friction process is not separated, but the coating liquid simply adhered to the surface of the dough is peeled off by friction, and as a result, the coating liquid applied on the dough is made into small dots. It spreads evenly over the surface of the dough, forming a crack pattern and showing a mixed light color tone.

In addition, the friction process is carried out in about 30 minutes to 2 hours, if the friction time is less than the lower limit is insufficient friction, if more than the upper limit is inadequate in terms of strength and color development of the fabric is carried out within the above range. Of course, by adjusting the degree of adhesion of the coating liquid to the dough according to the degree of friction it is possible to control the color (전체) of the entire color of the fabric.

Therefore, according to the irregular striped coating fabric and the manufacturing method of the present invention, when the color of the dough and the color of the coating liquid applied thereon are appropriately selected through the same color contrast and complementary color of the color, a unique two-color striped effect is obtained.

When described with reference to the accompanying drawings in order to more easily understand the characteristics of the irregular striped coating fabric and its manufacturing method according to the present invention.

1 is a photograph illustrating an example of an irregular striped coating fabric (A) according to the present invention, and as shown schematically in FIG. 2, the irregular striped coating fabric (A) according to the present invention has a myriad of stripes (1). And the crack pattern 2 are irregularly mixed as a whole to form a three-dimensional surface, and a large number of the naps 3 are also formed by the friction process.

That is, as illustrated in Figure 3, the irregular striped coating fabric (A) according to the present invention, the basic height (a) of the surface is usually about 1mm, but the height of the stripes (b) by the formed stripes (2) up to 3- It becomes about 4 mm and forms three-dimensional surface. Therefore, the irregular striped coating fabric (A) according to the present invention is reduced in width by about 5-30 cm than the width before the raw material.

As shown in Figure 4, the irregular striped coating fabric (A) according to the present invention is gathered in the width direction after twisting and twisting the wrinkles, and is located between a pair of upper and lower plate pressing members 30, 40 By pressing the pressing process, a myriad of irregular wrinkles are formed on the surface of the dough.

More specifically, the less overlapped cow overlap (X) is the hair on the surface of the dough inside, that is, the nap (3) is standing up and less wrinkles, while the more pressed large overlap (Y) is the dough surface Squeeze of the surface of the dough is eliminated and the hair is smooth and a lot of overlapping wrinkles are formed.

When the pressure given by the pair of plate pressurizers 30 and 40 in the pressurization process is 30 kgf / cm 2 or less, the stripes are not securely fixed and the stripes tend to be unstable, and when the upper limit exceeds 200 kgf / cm 2. Since the processed dough may be damaged, it is adjusted within the range of 30-200 kgf / cm 2.

In the manufacturing process of the irregular striped coating fabric (A) according to the present invention, the coating step is a step of applying a coating liquid consisting of pigments, acrylic resins or polyurethanes, or mixtures thereof and other additives such as softeners on the surface of the dough, The coated dough is usually dried at 80-180 ° C.

As a result of the subsequent friction process, a plurality of naps 3 are formed on the surface of the dough and at the same time, as the coating solution impregnated between the tissues of the dough is released, the coating solution is formed in a plurality of small spots. It becomes mixed and shows a light hue.

Irregular striped coating fabric (A) of the present invention as described above the stripes (1) and the cracked pattern (2) is mixed and the portion with and without the portion with the nap (3) on the surface of the stripe and the coated portion of Fabrics with different colors can be produced, stripes are formed in three-dimensional patterns with different heights, and the glossiness is different across the entire surface to create a subtle atmosphere that varies in color depending on the angle of light.

Representative examples will be described in order to more easily understand the irregular striped coating fabric according to the present invention having the features described above, these examples are intended to help the understanding of the present invention and claims It will be readily understood by those skilled in the art that modifications and variations are possible within the scope described.
