Description

  The present invention relates to a fabric to which a support is releasably bonded, particularly to a fabric with a support suitable for automatic cutting with a pattern designed using a computer in a garment design process, and a method for producing the same. .

  Usually, in the design of clothes, a patterner designed by a computer based on a design image drawn by a designer is designed by a computer, and based on this pattern, three-dimensionalization is performed with fabric, thereby confirming the design, so-called Three-dimensional confirmation is performed. In this three-dimensional confirmation, after the pattern is corrected, the pattern is finally determined and the design of the clothing is completed. At this time, it is known that a computer processing method is introduced, the fabric is set directly on the automatic cutting machine, the extension is directly written on the fabric, and this is automatically cut. Can be greatly reduced, and the work process for confirming the three-dimensional design can be greatly improved.

As a design confirmation fabric that can be set directly on an automatic cutting machine, Patent Literature 1 discloses a fabric in which a support and a fabric are bonded with a peel strength of 30 to 300 g / inch via a non-re-adhesive resin. In Patent Document 3, the support and the fabric are bonded via a thermoplastic resin so that the peel strength between the resin and the fabric is smaller than the peel strength between the resin and the support and the peel strength is 1 to 100 g / 25 mm. Each fabric has been proposed.

  Here, although the fabric with a support for design confirmation described in Patent Document 1 uses a vinyl chloride resin as a non-re-adhesive resin so as not to cause re-adhesion after peeling of the fabric and the support, After cutting, the resin may remain on the fabric side when the fabric is peeled off from the support. Further, the balance between bonding and peeling is insufficient, and in the examples, the non-re-adhesive resin is 0.5 to 1.5 mm in diameter (1.0 mm and 1.2 mm in the examples) in order to obtain such a balance. Since the support and the fabric are bonded to each other in a large dot shape, irregularities appear on the surface of the fabric, and the line may be distorted when applied to an automatic drafting machine.

  Moreover, in the fabric with a support for design confirmation described in Patent Documents 2 and 3, in order to prevent the resin from remaining on the fabric side at the time of peeling, the peeling strength between the resin and the fabric is determined by peeling between the resin and the backing. Although it is set smaller than the strength, as a specific achievement means, since two or more layers of thermoplastic resin are used, there is a problem that the texture becomes hard as a whole and it is difficult to put on a plotter. Moreover, since there are two resin layers, the number of manufacturing steps is large and the cost is high.

Accordingly, an object of the present invention is to provide a fabric with a support for design confirmation which is excellent in the balance between peeling and adhesion and excellent in fabric uniformity and texture.
Another object of the present invention is to produce a fabric with a support for design confirmation having the excellent performance as described above, simply and inexpensively.

  That is, as a result of various studies, it has been found that the above object of the present invention is achieved by the following configuration.

(1) A fabric with a support, wherein the fabric is detachably bonded to the support via an acrylic resin layer containing a thermoplastic resin powder.
(2) A method for producing a fabric with a support, characterized in that an acrylic emulsion in which a thermoplastic resin powder is dispersed is applied onto a support, dried and fixed, and then superposed on the fabric and heated to be integrated.
(3) The method for producing a fabric with a support as described in (2) above, wherein the acrylic emulsion is applied onto the support by a gravure coating method.

  According to the present invention, the fabric and the support are bonded to each other via the acrylic resin layer containing the thermoplastic resin powder, so that the fabric and the support are integrated in a detachable manner. You can get a fabric.

  As an adhesive component, an acrylic resin containing a thermoplastic resin powder is used, and by performing a heat treatment during bonding, the thermoplastic resin powder held in the acrylic resin layer is effectively bonded to the fabric, and the acrylic resin layer Therefore, even if the support is peeled from the fabric after automatic cutting, it can be easily peeled without leaving the resin component on the fabric. That is, according to the present invention, it is possible to provide a fabric with a support having an excellent balance between adhesion and peelability between the support and the fabric.

Furthermore, since the thermoplastic resin is contained in the acrylic resin layer as a fine powder, preferably as a fine powder having a diameter of 5 to 15 μm, the uniformity can be maintained without causing unevenness on the fabric surface.
Moreover, since the application | coating process of an contact bonding layer can also be performed by one process, a manufacturing process is simple and can be provided cheaply.
Therefore, according to the present invention, it is possible to easily and inexpensively obtain a fabric with a support for design confirmation that is excellent in the balance between peeling and adhesiveness and excellent in fabric uniformity and texture.

The particle size of the thermoplastic resin powder is preferably 5 to 80 μm, and more preferably 5 to 15 μm. Within this range, it is preferable because it is easy to adjust the adhesive force under the bonding conditions, and the transfer of the adhesive resin to the surface side after peeling is reduced.

The acrylic resin layer of this invention means the resin layer which has an acrylic resin as a main component, and may contain other resin components, for example, urethane resin etc.
The acrylic resin is preferably an acrylic resin using an acrylic polymer in which a main component monomer is a (meth) acrylic acid alkyl ester and a polar monomer component is copolymerized therewith. The acrylic acid alkyl ester is an alkyl ester of acrylic acid or methacrylic acid, and is not particularly limited. For example, ethyl acrylate, isopropyl acrylate, n-butyl acrylate, isobutyl acrylate, (meth) Examples include pentyl acrylate, 2-ethylhexyl (meth) acrylate, isooctyl (meth) acrylate, isononyl (meth) acrylate, decyl (meth) acrylate, and lauryl (meth) acrylate.

An acrylic resin can be used as a composition which can mix | blend with a crosslinking agent and can bridge | crosslink an acrylic polymer. As the crosslinking agent, for example, polyisocyanate compounds such as aliphatic diisocyanates, aromatic diisocyanates, and aromatic triisocyanates are used. Furthermore, a crosslinking accelerator composed of an organometallic compound or the like can be added to those having a slow crosslinking reaction.
A plasticizer can be added to the acrylic resin. Examples of the plasticizer include adipic acid ester, glycol ester, sebacic acid ester, trimellitic acid ester, pyrometic acid ester, phthalic acid ester, and phosphoric acid ester. When used for an acrylic resin, a phthalate ester type is preferable, but not limited thereto.

In this invention, as shown in FIG. 1, the fabric 1 is adhere | attached on the support body 3 so that peeling is possible via the acrylic resin layer 5 containing a thermoplastic resin powder. In the acrylic resin layer 5, the thermoplastic resin powder may be uniformly dispersed in the acrylic resin layer 5, or unevenly distributed in the acrylic resin layer 5, for example, as shown in FIG. 2. It may be contained, and the thermoplastic resin powder layer component 5 ″ may be laminated on the upper layer portion of the acrylic resin layer component 5 ′.
Although content of the thermoplastic resin powder in an acrylic resin layer is not specifically limited, It is preferable that it is 5-30 mass%, More preferably, it is 10-20 mass%.

The acrylic resin layer can be easily provided by dispersing thermoplastic resin powder in an emulsion, solution, dispersion, or the like containing acrylic resin as a main component, coating the support on a support, and drying and fixing. A coating method is not particularly limited, and the coating can be performed on a support by a known method. For example, spray, gravure coater, knife coater, roll coater, comma coater and the like can be mentioned. Among these, the gravure coater method is preferable in that unevenness in the coating amount hardly occurs. Moreover, you may provide an acrylic resin layer on a support body by methods, such as an extrusion coating method and a dry lamination method.
Preferably, a method in which a thermoplastic resin powder is dispersed in an acrylic emulsion, coated on a support, and dried and fixed is preferable.
Further, the acrylic resin layer 5 in which the thermoplastic resin powder layer component 5 ″ as shown in FIG. 2 is unevenly distributed in the upper layer portion of the acrylic resin layer component 5 ′ is, for example, after an acrylic emulsion is applied on the support. Subsequently, the thermoplastic resin powder can be scraped off and dried.

  After the acrylic resin layer containing the thermoplastic resin powder is provided on the support, the support and the fabric can be integrated by superimposing on the fabric and heating. As a means for adhering both, a method of using a heat roll device in a winding form, a method of using a heat press or the like in a flat form may be used, but a method of forming in a winding form is preferable from the viewpoint of efficiency. The heat roll device may be one in which the heat rolls face each other, or only one of them may be a heat roll. When only one is a heat roll, it is preferable to set a support body to the heat roll side from a viewpoint of fabric protection. The heating temperature and heating time can be appropriately selected and set depending on the type and content of the thermoplastic resin used, the thickness of the resin layer, the presence or absence and type and amount of additives, and the type of fabric and support. The heat treatment is preferably performed at 80 to 140 ° C.

  In the fabric with a support of the present invention, it is common to draw a cutting line on the support, then cut it with the cutting line, peel it off and sew it. Alternatively, the sewing line of the mold may be drawn on the fabric, or may be cut with a cutting line, and the support may be peeled off for sewing. For thin fabrics that are difficult to handle due to lack of strain, it is possible to sew without peeling, if necessary, and then peel the support.

  The sewing line or cutting line may be handwritten, and the cutting method may be manual, but the computer can be selected from many types and sizes memorized using a computer or a computer-designed mold. By directly drawing as output or cutting with an automatic cutting machine, the function of the fabric with a support of the present invention is efficiently exhibited.
