In the fixing step S3, the lower layer resin portion 4 is formed by fixing the resin composition R1 onto one main surface 3a of the base fabric 3, and then the resin composition R2 is fixed onto the surface 4a of the lower layer resin portion 4. Then, the adhesive resin portion 5 is formed.

The lower layer resin portion 4 is formed by, for example, applying a paste-like resin composition R1 to one main surface 3a of the base fabric 3 in dots using a cylindrical screen that rotates around a predetermined rotation axis. formed by In this case, a squeegee for supplying the resin composition R1 is provided in the screen. The resin composition R1 supplied from the squeegee is extruded through the through-holes of the screen and adheres onto the main surface 3a.

The adhesive resin portion 5 is formed, for example, by spraying powder of the resin composition R2 on the main surface 3a on which the lower layer resin portion 4 is formed and making the powder adhere to the lower layer resin portion 4 . The powder of resin composition R2 is dispersed using, for example, a hopper or scatter. Excess powder of the resin composition R2 dispersed on the base fabric 3 may be removed. For this purpose, for example, the excess powder of the resin composition R2 on the base fabric 3 may be blown off by air blowing.

The lower layer resin portion 4 and the adhesive resin portion 5 may be formed by, for example, an embossing roll method or a spray method, without being limited to the above method.

Simultaneously with the fixing step S2 or after the fixing step S2, the base fabric 3 is heated in a heating step S3 to sublimate the dye mixture and dye the bonded portion 6. As shown in FIG. Only the adhesive resin portion 5 of the adhesive portion 6 may be dyed, or the lower layer resin portion 4 may be dyed together with the adhesive resin portion 5 .

The heating step S3 comprises a first heating step S31 of heating the adhesive resin portion 5 at a first temperature to evaporate the water content of the resin composition R2, and then heating the base fabric 3 at a second temperature higher than the first temperature. and a second heating step S32 for dyeing the adhesive resin portion 5 by sublimating the dye mixture by heating.

The first temperature of the first heating step S31 may be 80°C to 160°C, or 120°C to 160°C. The heating time of the first heating step S31 may be 5 seconds to 120 seconds, or 10 seconds to 60 seconds. By the first heating step S31, the powder of the resin composition R2 can be aggregated to form one (see FIG. 3) or two (see FIG. 4) adhesive resin portions 5 on one lower layer resin portion 4. FIG.

The second temperature of the second heating step S32 may be 160°C to 230°C, or 170°C to 210°C. The heating time of the second heating step S32 may be 5 seconds to 120 seconds, or 10 seconds to 60 seconds. By the second heating step S22, part of the dye mixture for dyeing the base fabric 3 is sublimated and adheres to the surface of the adhesive part 6 (especially the adhesive resin part 5). As a result, the adhesive part 6 or the adhesive resin part 5 is dyed with the dye mixture. Heating at the second temperature promotes agglomeration of the adhesive resin portion 5 and can reduce its surface area. When the surface area is reduced, diffused reflection is reduced, so that glitter can be further suppressed.

In the above embodiment and its modifications, examples of the colored adhesive interlining 1 in which one or two adhesive resin portions 5 are arranged on one lower layer resin portion 4 have been described. is not limited to For example, as in a modification shown in FIG. 7, three or more adhesive resin portions 5 may be arranged on one lower layer resin portion 4 .

EXAMPLES Hereinafter, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to the following examples.

[Evaluation of resin coloring (glitter)]
"Glitter" tends to occur when there is a difference in color tone between the adhesive resin portion and the base fabric. Therefore, if the resin coloration evaluation is good, glitter can be suppressed. Evaluation of resin coloration was performed by the following method.

Dye mixtures of Examples 1 to 11 and Comparative Examples 1 to 5 were prepared by mixing the respective dyes in the proportions shown in Table 1. A dyed fabric was obtained by dyeing a polyester fabric with the dye mixture. A polyamide resin for adhesive resin (manufactured by M-Schemie Japan Co., Ltd.) was sandwiched between two pieces of release paper, an iron was placed on the release paper, and heated and pressed at 200 ° C. for 3 minutes to obtain a polyamide resin film. .

Next, release paper, white cotton cloth, polyamide resin film, dyed cloth, and release paper were laminated in this order. The resulting laminate was subjected to dry heat treatment at 160° C. or 180° C. for 3 minutes, and the polyamide resin film was dyed with the dye mixture sublimated from the dyed cloth.

The degree of coloring was visually compared between the dyed polyamide resin film and the dyed cloth. "◎" when there is no difference in the degree of coloring between the two and no uneven coloring in the polyamide resin film, and when there is little difference in the degree of coloring between the two and there is little uneven coloring in the polyamide resin film "○", the difference in the degree of coloring between the two is large (the coloring density in the polyamide resin film is remarkably high, or color loss occurs), and the coloring unevenness in the polyamide resin film is large. was evaluated as "×". When the evaluation is "⊚" or "◯", it is determined that glitter can be suppressed.

[Dry heat contamination (sublimation fastness) evaluation]
The sublimation fastness of the dye mixture was evaluated by performing a dry heat stain evaluation by the following method based on the dry heat test of JIS L 0879. Dyed fabrics obtained by dyeing polyester fabrics with the dye mixtures of Examples 1 to 11 and Comparative Examples 1 to 5 were sandwiched between white polyester fabrics and subjected to dry heat treatment at 160° C. or 180° C. for 30 seconds. . The degree of contamination of the polyester white cloth after the dry heat treatment was judged based on the JIS L-0805 gray scale for contamination. A higher class number means less contamination.

At both 160 ° C. and 180 ° C., if the dry heat stain evaluation is grade 3-4 or higher and the resin coloring evaluation is "◎" or "○", the sublimation fastness is excellent, and Glitter can be suppressed.

[Preparation of colored adhesive interlining and adhesive cloth]
A plain weave green fabric woven using polyester false twisted yarn was scoured by a conventional method to prepare a base fabric. The scoured base fabric was dyed black using the dye mixtures of Examples 1-6 or Comparative Examples 1-5. The resulting dyed fabric was subjected to a water repellent treatment and an anti-shrink treatment. The water repellency point of the dyed fabric was grade 3.

A dot-shaped lower layer resin portion was formed on one main surface of the dyed cloth using an acrylic acid ester copolymer having a glass transition point Tg of 0°C. An adhesive resin portion was formed on the lower layer resin portion using a polyamide-based hot-melt adhesive having a glass transition point Tg of 45°C. As a result, dot-shaped adhesive portions composed of the lower layer resin portion and the adhesive resin portion were formed on the base fabric.

Next, the lower layer resin portion and the adhesive resin portion were dyed by sublimating the dye mixture to prepare a colored adhesive interlining. The obtained colored fusible interlining is superimposed on a black-dyed 100% wool plain weave fabric (outer fabric) and heated under pressure at 130° C. for 10 seconds at 0.3 MPa to form a colored fusible interlining on the surface. By pasting together, an adhesive cloth was obtained.

In the dye mixtures of the examples, the discoloration of the outer material caused by the dye sublimated from the colored adhesive interlining was suppressed as compared with the dye mixtures of the comparative examples. That is, the colored adhesive interlining using the dye mixtures of the examples was excellent in sublimation fastness. In addition, when dyed with the dye mixture of the example, the glistening of the adhesive cloth was suppressed as compared with the case of dyeing with the dye mixture of the comparative example.
