JP-A-9-143866

  An object of the present invention is to provide a pattern fabric in which a fabric is bonded in a pattern to a body fabric, and a method for easily and inexpensively manufacturing the pattern fabric without damaging the fabric.

  The present invention includes a step (a) of forming a patterned hot-melt adhesive layer on one surface of a fabric, a step (b) of applying a discharge agent to the outline of the hot-melt adhesive layer, The present invention relates to a method for producing a patterned fabric, comprising: a step (c) in which a surface having a melt adhesive layer and a body cloth are superposed on each other and thermocompression bonded; and a step (d) in which a portion of the fabric not having a hot melt adhesive layer is removed. .

  In the said manufacturing method, it is preferable after the process (b) to include the process of (e) heating this fabric at 100-140 degreeC, Furthermore, 120-125 degreeC.

  In the manufacturing method, the cloth is preferably a cloth made of a natural material.

  Moreover, this invention relates to the pattern fabric manufactured by the said manufacturing method.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to manufacture easily at low cost, without damaging a cloth, regardless of the kind of cloth, regardless of the kind of cloth, the cloth on which the cloth was adhere | attached in the pattern shape on the body cloth.

  The method for producing a patterned fabric according to the present invention includes a step (a) of forming a patterned hot melt adhesive layer on one surface of the fabric, and a step of applying an extractant on the outer surface of the hot melt adhesive layer (b) ), A step (c) in which the surface of the fabric having the hot-melt adhesive layer and the body cloth are stacked and heat-pressed, and a portion (d) in which the portion of the fabric having no hot-melt adhesive layer is removed. .

  In the present invention, as the pattern forming fabric, natural materials such as woven fabric, non-woven fabric, and knitted fabric obtained from cotton, hemp, silk, etc. are preferably used. These fabrics may be obtained from a single fiber, or may be obtained by combining two or more kinds of fibers. Further, depending on the use of the pattern fabric, the whole or a part of the pattern forming fabric may be colored.

  The body of the pattern fabric is not particularly limited as long as it can be firmly bonded to the pattern forming fabric by a hot melt adhesive and does not change its shape by heat at the time of pressing, and cotton, hemp, Woven fabrics, non-woven fabrics, knitted fabrics and the like obtained from various natural fibers or synthetic fibers such as silk, wool, polyester, acrylic, nylon, rayon and acetate are used. Moreover, the whole body cloth or a part of it can also be colored according to the use of a pattern fabric.

  As the discharging agent, a commonly used discharging agent can be appropriately selected depending on the type of the fabric for pattern formation. For example, when the pattern-forming fabric is made of cotton, an extractant made of sodium hydrogen sulfate, tamarint gum, a surfactant, a polyhydric alcohol and water is preferably used. When such an extractant is used, the mixing ratio of sodium hydrogen sulfate, tamarint gum, surfactant, polyhydric alcohol and water in the extractant is 5 to 30% by weight: 1 to 10% by weight: 0.1. -5 wt%: 5-30 wt%: 55-80 wt%, preferably 10-20 wt%: 1-5 wt%: 0.5-3 wt%: 10-20 wt%: 60- More preferably, it is 70% by weight. If the blending ratio is out of the above range, the fabric may not be sufficiently removed, or the fabric may be excessively removed and the target pattern may not be formed.

  It does not specifically limit as a hot-melt-adhesive, Hot-melt-adhesives, such as a polyamide type, polyester type, and urethane type, used normally can be used.

  The manufacturing method of the pattern fabric of this invention is demonstrated using FIG. First, a patterned hot-melt adhesive layer 2 is formed on one surface of the pattern-forming fabric 1 (step (a)), and an extractant 3 is applied to the outer surface of the hot-melt adhesive layer 2. (Step (b)). The order of the formation of the hot melt adhesive layer 2 and the application of the discharge agent 3 is not particularly limited. The hot melt adhesive layer 2 is formed in a pattern on the fabric by, for example, printing with a silk screen or the like. Similarly, the discharging agent 3 is applied only to the outer portion of the hot melt adhesive layer by printing with a silk screen or the like.

  In the pattern forming fabric, a film 4 made of polyester, western paper, Japanese paper or the like is pre-synthesized on a surface different from the surface on which the hot melt adhesive layer 2 is formed so that the pattern shape does not collapse after heating. It is preferable to temporarily bond with a resin adhesive or the like.

  In the portion where the discharging agent 3 is applied, the pattern forming fabric is discharged and the discharged portion 5 is formed. Also, as shown in FIG. 2, after applying the extractant 3, the fabric is preferably heated at 100 to 140 ° C., more preferably 120 to 125 ° C., before the body cloth is stacked, thereby removing the extracted portion. 5 is easily formed (step (e)). If the heating temperature is too high, the fabric tends to be excessively yellowed and the fabric tends to turn yellow. If the heating temperature is too low, the electrical discharge tends to be insufficient. The heating of the fabric is preferably performed using a tunnel heater from the viewpoint that the entire fabric can be heated uniformly. The heating time is appropriately adjusted depending on the type of fabric and the extractant.

  A pattern-shaped hot melt adhesive layer 2 is formed, and the surface of the fabric having the hot melt adhesive layer 2 applied to the outer periphery of the hot melt adhesive layer 2 is overlapped with the body cloth 6. The pattern forming fabric is bonded onto the body cloth by thermocompression bonding (step (c)). A press transfer machine is used for thermocompression bonding.

  Although it will not specifically limit if the heating temperature at the time of thermocompression bonding is more than the temperature which a hot-melt-adhesive melt | dissolves, it is preferable that it is 145-165 degreeC, and it is more preferable that it is 150-155 degreeC. If the heating temperature is too low, the pressure bonding is insufficient, and if the heating temperature is too high, the fabric will be burned.

  After the pattern forming fabric 1 is adhered to the body cloth 6 by thermocompression bonding, the pattern forming fabric 1 and the film 4 not having the hot melt adhesive layer 2 are removed, for example, manually, and washed with water. A patterned fabric in which the fabric 1 is adhered in a pattern on the body fabric 6 can be obtained (step (d)).

  The pattern fabric obtained by the production method of the present invention is free from damage caused by heat or an extractant on the body fabric or pattern forming fabric, and also when a colored body fabric or pattern forming fabric is used. There is no change such as discoloration or fading after processing.

  The patterned fabric obtained by the production method of the present invention is widely used for apparel such as T-shirts, trainers, pajamas, handkerchiefs, bags and the like.

  EXAMPLES Hereinafter, although an Example demonstrates this invention concretely, this invention is not limited to these Examples.

Example 1
Spray bond (strong spray bond, manufactured by Ozawa Kogyo Co., Ltd.) is sprayed on the colored surface of the cotton pattern forming fabric colored jeans pattern, and a polyester transparent film (Teijin DuPont Film Co., Ltd.) is used as the fabric. Temporarily bonded to the entire surface. On the surface opposite to the colored surface of the fabric, 15 g of sodium hydrogen sulfate (Opal H, manufactured by PC Kasamatsu), a mixture of tamarind gum and a surfactant (opal powder PC, on the outline of the word “Round Over the Globe”) After applying an extractant consisting of 5 g of PC pine and 15 g of polyhydric alcohol (Sintor No. 8, made of PC pine) and 65 g of water using a silk screen, urethane hot melt adhesive (NT64) is applied on the letters. The layer was formed by silk screen. When the obtained pattern forming fabric was heated at 120 ° C. for 90 seconds with a tunnel heater (MULT, manufactured by Cincinnati), only the outer portion of the character coated with the extractant burned brown. After superposing the surface on which the hot melt adhesive layer of this fabric was formed and the cotton fabric, it was subjected to thermocompression bonding at 155 ° C. for 20 seconds using a press transfer machine (HP-84A, manufactured by HASHIMA Co., Ltd.). After thermocompression bonding, the pattern forming fabric and the body cloth were bonded at the portion where the hot melt adhesive layer was formed. The unbonded portion of the pattern forming fabric and the temporarily bonded film were manually removed and then washed with water to obtain a patterned fabric. The obtained patterned fabric was formed with the letters “Round Over the Globe” formed by 17 pieces of fabric that were finely cut on the body fabric. The cut fabric was firmly bonded on the body fabric, and the coloring state of the jeans pattern was hardly changed before and after the treatment. Moreover, the pattern formation fabric and the body cloth were not damaged.
