Description

Brushed fabric having designs

The present invention relates to a brushed fabric with a design, and more specifically, a texture raising effect that gives a design that can be used as a garment for sportswear, T-shirts, and interior fabrics such as sofas, chairs, and carpets. It is about fabric.

As an additional processing for maximizing sensitivity, there is a brushing method and an embossing method among the surface change processing technologies that improve the shape of the fabric surface and create a new handle. The napping process is called peach processing because it produces fine hairs similar to the fine hairs on the surface of the peach. This processing method is used for high-end garments by processing fine hairs on the fabric surface to make the fabric feel natural and soft.

However, the following three methods can be given to designing such a brushed fabric in general.

The first method is a method of expressing a design by using a loom of a raised fabric or a dobby loom or jacquard loom during weaving. This method can express various designs and has the advantage of being suitable for mass production according to the same design, but it is not suitable for producing small quantities of various designs quickly and in low cost in response to changes in fashion trends.

The second method is a method of directly imprinting a desired design on a fabric by using an embossed roller imprinted with post-processing heat. This method is convenient and productive when fusing simple designs such as stripes or polka dots, but the durability is very poor after washing, the design implemented in the product is not delicate, lacks naturalness, and the design is applied when applying high temperature heat. There is a problem that is erased.

The third method is to give a design by computer design shearing the raised surface of the fabric. This method has the advantage of being able to express quickly and various patterns, but there is a problem that the design embodied in the product is not delicate and the mass productivity and economy are poor.

Accordingly, the technical problem to be achieved by the present invention is to provide a method for manufacturing a raised fabric fabric that can solve the problems of the conventional method described above, but can be effectively given a delicate design by a simple process.

Another technical problem to be achieved by the present invention is fabricated by the method described above to give a texture processing effect is given to a design that can be used as a garment for sportswear, T-shirts, etc. and interior fabrics, such as sofas, chairs, carpets To provide.

A plurality of concave portions are arranged on the surface of the terry knitted fabric or terry fabric to provide a raised fabric characterized in that a desired design is expressed.

In one embodiment of the present invention, it is preferable that the plurality of recesses are arranged in the front, rear, left and right with an interval of about 5 to 25 mm from each other.

In one embodiment of the present invention, the recess has a rectangular pattern having a length of 3 to 12 mm or a circular dot pattern having a diameter of 3 to 12 mm independently of each other. It is preferred that the depth is 3 to 5 mm.

Hereinafter, a method for manufacturing a brushed fabric imparted with a design according to the present invention and a brushed fabric imparted with the manufactured design will be described in detail.

The method of manufacturing a brushed fabric given a design according to the present invention is made in the following order.

(1) fixing agent pattern forming process (printing step)

First, referring to FIG. 4A, a fixing agent pattern 22 expressing a desired design is formed by printing a fixing agent on the surface of the terry knitted fabric or the terry cloth 20 by the roller printing method.

The printing step of forming the fixing pattern has a square pattern having a length of 3 to 12 mm or a circular dot pattern having a diameter of 3 to 12 mm each independently of a length of 3 to 5 mm. It is preferable to use a roller printer having a stamping pattern in which a plurality of markings are arranged in a plurality of front and rear, rearward, rearward and rearward at intervals of 5 to 25 mm.

The kind of raising fabric that can be used in the present invention is not particularly limited, but a terry cloth or a terry knitted fabric in which pile yarns protrude to the surface and / or the back side of the tissue is preferable.

Figure 1 shows a longitudinal cross-sectional view of a terry fabric which is one of the raising fabric that can be used in the present invention.

Referring to Figure 1, the terry fabric according to one aspect that can be used in the present invention is formed by the local slope (3, 3 ') and weft yarns (5) to form a separate pile slope (1) to arrange this As a pile or loops on the fabric side. The fleece fabric that can be used in the present invention is preferably a terry cloth or terry knitted fabric having a weight of 180 to 300 g / m ² and a pile length of 1.5 to 2.5 mm. If the pile length is out of the above range, the fusion does not occur satisfactorily in the fusion process described below, and there is a problem that the design effect imparted to the fabric is not as good as the design effect obtained in the above range. The thickness of the false twist yarn of the local warp yarns 3 and 3 'is 75 to 180 deniers (d), the thickness of the false twist yarn of the weft yarn 5 is 75 to 150 d, and the thickness of the false twist yarn of the pile warp yarn 1 is 75 to 300 degrees. It is preferable that it is d.

The fabric is preferably made of a synthetic fiber yarn having a thermoplastic, such as polyester yarn, nylon yarn, acrylic yarn. This is because a fabric made of thermoplastic yarn without thermoplastics does not have subsequent thermal fusion. In addition, mixed yarns in which these natural synthetic yarns such as thermoplastic synthetic fibers and cotton yarns and wool yarns are mixed may be used to prepare a terry cloth or terry knitted fabric which can be used in the present invention by being partially mixed as long as they exhibit heat sealing property. In addition, two or more thermoplastic polymers such as polyester / nylon split microfiber, polyester / acrylic split microfiber, polyester / polystyrene split microfiber, polyester / nylon composite yarn, polyester / acrylic composite yarn, polyester / polystyrene composite yarn, etc. Split microfiber yarns, composite yarns, etc. may be used.

The fixing agent which can be used in the present invention increases the heat absorption and efficiently melts the thermoplastic material, and is prepared by mixing the carbon powder and the water-soluble binder so that the terry cloth or the terry knitted fabric does not aggregate to further disperse the powder. will be. The mixing ratio of the water-soluble binder to the carbon powder is preferably 10 to 120 parts by weight, more preferably 20 to 60 parts by weight, and even more preferably 30 to 50 parts by weight based on 100 parts by weight of the water-soluble binder. If the content of the carbon powder is less than 10 parts by weight, there is a problem that the heat adsorption efficiency is not satisfactory, and if it exceeds 120 parts by weight, there is a problem that the adhesion to the terry knit fabric or fabric is poor.

Although the carbon powder which can be used by this invention is not specifically limited, For example, carbon black, acetylene black, ketene black, activated carbon, etc. can be used 1 type or in mixture of 2 or more types.

The water-soluble binder that can be used is not particularly limited, but specific examples thereof include starch, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, acetyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, carboxymethyl starch, carboxyethyl starch and hydroxyethyl starch. , Acetyl starch, polyvinyl alcohol, polyvinylacetate, partially saponified polyvinyl acetate, polyvinyl butyral, polyvinyl acrylate, glue and the like can be used alone or in combination.

(2) heat fusion process

Referring next to FIG. 4B, heat and pressure are applied to heat the fuser and the terry or knitted fabric to fuse the adherent pattern 22 adhered onto the terry or terry knitted fabric 22 in the desired design shape. Thermal fusion is preferably performed using a calender machine under heat of 130 ° C to 200 ° C and a pressure of 2,000 to 8,000 kg / m ² . More preferably, heat fusion is carried out using a calender machine under heat of 130 ° C to 180 ° C and a pressure of 3,000 to 5,000 kg / m ² . Conventional heat fusion is usually carried out using a hot oven, a stenter, or a heater, but in the case of a terry cloth or a terry knitted fabric having a plurality of piles (loops) as in the present invention, the yarn itself is fused. However, it was found by repeated experiments by the present inventors that the loop structure cannot effectively thermally bond to the pile. Therefore, the present inventors could effectively achieve heat fusion using a calendar instead of these heat ovens, stenters and the like.

The heat and pressure of 130 ℃ and less than 2,000 kg / m ² has no problem of raising and non-fixing part, so there was a problem in raising effect, and when the heat and pressure exceeding 200 ℃ and 8,000 kg / m ² were applied, The fusing effect was halved because the file was not raised.

Referring to Fig. 4C, when the time to which heat and pressure applied by the calender is increased increases, the fusion surface on which the adhesive pattern 22 is fused with the terry cloth or the terry knitted fabric 22 is reliably pressed by the stamp on the roller printer. A pattern, that is, a recess pattern is formed.

On the other hand, the rotational speed of the calender used in the heat fusion process is 10 to 25 m / min was suitable, especially when adjusted to 15 m / min was the most effective when considering the degree of thermal fusion and process speed.

(3) raising process

Finally, the area covered with the fixing agent and the area not covered with the fixing agent are mixed in the previous process, and as a result, the terry cloth or the terry knitted fabric having the desired design pattern is passed through the brush. Referring to FIG. 4D, the area covered with the fixing agent during the passage of the brush is protected by the fixing agent so that it is not brushed by the brush 24 of the raising machine, while the pile of the area not covered with the fixing agent is the loop rotor of the raising machine. Raised by the trim. At this time, since the hair is raised and at the same time the hair is not covered with a fixing agent to form a recessed portion, the remaining region to form a convex portion 21 of the looped form as shown in Figure 4e The design of the fixing pattern is three-dimensionally transferred to the raising fabric.

By changing the design pattern imprinted on the surface of the printer roller used when printing the fixing agent, it is possible to change the design formed on the terry fabric or the terry knitted fabric. That is, various patterns, such as a checkered pattern, a stripe pattern, and a polka dot pattern, can be formed by the simple method by the change of the design formed on the printer roller.

On the other hand, in order to produce a natural brushing effect, the hair removal process, the hair raising process and the bias shearing process (bias shearing) may be further performed after the brushing process to obtain a natural three-dimensional effect.

2 is a plan view of a raised fabric according to an embodiment of the present invention having a design in which recesses are arranged at regular intervals, and FIG. 3 is a cross-sectional view taken along line AA ′ of FIG. 2.

2 and 3, the raised fabric 10 formed in one embodiment of the present invention is a rectangular or square shaped recess having a horizontal and vertical on the surface of the terry cloth protruding pile yarns (not shown) ( 12) consists of regularly arranged designs. The horizontal length (a) and the vertical length (b) of the rectangular or square recessed portion 12 are each about 3 to 12 mm, and the depth is 3 to 5 mm, which is preferable in view of stable fixation and natural appearance effect. . The recessed part 12 of FIG. 2 corresponds to the recessed part 26 in FIG. 4E, and the region of the convex part 13 between the recessed part 12 and the recessed part 12 in FIG. 2 is a concave-shaped convex part in FIG. 4E. Corresponds to (21).

The distance (c) between the recess and the recess is not particularly limited, but is preferably adjusted to about 5 to 25 mm in terms of maximizing the recess and protrusion effect.

The brushed fabric given a design by the above process can be used as a garment for sportswear, T-shirts and the like, and for the interior fabrics of sofas, chairs, carpets, etc., by giving a texture processing effect.

Hereinafter, the present invention will be described in more detail with reference to the examples, which are merely illustrative and the present invention is not limited thereto. This will make the features and other advantages of the present invention clear.

Example

The pile is formed only on the surface of the paper tissue by using polyethylenetetephthalate (PET) yarn having a thickness of 75 to 150 d and a single yarn having a thickness of 1 to 3 d as the pile inclination (1). It is used as a weft weave of the tissue, and weaved to prevent slipping because it is typed to have a slope (3, 3 ') density of 50 bones / inch to 80 bones / inch and a density of yarns (5) of 70 bones / inch to 90 bones / inch. Terry cloth was used. This terry fabric had a weight of 250 g / m ² and a pile length of 2.0 mm.

The fixing agent was printed on the surface of the terry cloth using an imprinting roller formed by repeatedly forming a dot pattern having a length of 4 mm, a length of 6 mm, and a depth of 4 mm. In this case, as the fixing agent, 30 parts by weight of carbon black (manufacturer; Yusung Co., Ltd., product name; 905BLW) having a particle size of 1 to 5 μm is added to water together with 15 parts by weight of flour starch and 15 parts by weight of glue, and the carbon black is uniformly dispersed. Was used.

The printed terrycloth was then passed through a calender machine adjusted to impart heat of about 180 ° C. and a pressure of about 5,000 kg / m ² to fuse PET twisted yarns in the area covered with the binder. The rotation speed of the calender was 15 m / min.

Subsequently, the terry cloth was passed through a raising machine (manufacturer; Hyupseong Co., Ltd., model name: INVT 93) whose pin angle was adjusted to about 15 degrees. In the course of passing through the brush, the pile of the area not covered with the fixing agent was brushed while being raised to form recesses.

Finally, the terry cloth is further subjected to the hair removal process, the hair removal process, and the bias shearing process to naturally raise the brushing effect, and the rectangular shape having a depth of 4 mm, a length of 4 mm, and a length of 6 mm is separated by 10 mm. A terry cloth with a regularly arranged design was obtained.

As described above, according to the method of the present invention, it is possible to efficiently manufacture the raising fabric given the design by a simple process.
