Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a painted nonwoven fabric, and more specifically, a nonwoven fabric is constructed by bonding fibers with a dyeable adhesive, and the adhesive is used as a transfer target. The present invention relates to a method for producing a decorated nonwoven fabric, which is characterized in that the surface of the nonwoven fabric is decorated by dyeing the adhesive surface.

In recent years, the uses of non-woven fabrics have expanded, and in order to further increase their utility value, methods have been used to increase the surface effect by forming arbitrary patterns directly on the surface of non-woven fabrics, for example, by printing or textile-dying.

However, when using printing, the nonwoven fabric tends to stretch due to the tensile force applied to the nonwoven fabric during printing, so it is difficult to match the printing register. allowances are required and therefore printing costs are high, and
Even if such precautions are taken, there is a drawback that it is difficult to obtain printed matter with good printing registration.

Furthermore, even with the printing method, registration is difficult and impractical when dyeing complex multicolored or delicate patterns;
The drawback is that the process itself is complicated and time-consuming, such as adjusting the viscosity of the color paste during the printing process, and steaming and washing with water after dyeing.

In order to improve the above-mentioned drawbacks, the present inventor conducted various researches and found that a transfer sheet is formed by forming an arbitrary pattern containing a thermally transferable dye on a support, and on the other hand, the above-mentioned dye is On the other hand, a non-woven fabric is constructed by bonding non-dyeable fibers with an adhesive that is dyeable to the above-mentioned dye, and then the patterned surface of the above-mentioned transfer sheet and the surface of the above-mentioned non-woven fabric are overlapped to combine both. When the transfer sheet is heated and pressurized and then peeled off from the nonwoven fabric, the dye in the pattern of the transfer sheet is transferred onto the nonwoven fabric, and the adhesive constituting the nonwoven fabric can be dyed. The present invention was completed by discovering that extremely elaborate and delicate patterns can be painted on with a good texture and very easily.

The present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a plan view illustrating such a transfer sheet.

As shown in FIG. 1, a transfer sheet 1 is prepared by applying an ink or coating composition containing a heat-transferable dye onto an arbitrary support 2 by a conventional printing method, drawing method, coating method, etc. , for example, by forming arbitrary monochrome or multicolor patterns 3 such as letters, symbols, and pictures.

In the above, as the support 2, for example, various kinds of paper,
A resin film, a metal foil, or a laminate sheet obtained by arbitrarily laminating these in a conventional manner can be used.

In addition, in the above, as the dye having thermal transferability, any colorant can be used as long as it has the property of being transferred to other substrates by the action of heat, for example, by phenomena such as sublimation, melting, or evaporation. can do.

For example, one or more of most disperse dyes, some basic dyes, some acid dyes, mordant dyes, oil-soluble dyes, and vat dyes can be used.

In the present invention, the ink or coating composition containing the above dyes is prepared by adding one or more of the above dyes to a normal ink or coating vehicle, and optionally adding other known additives. However, a composition obtained by sufficiently kneading with a solvent, diluent, etc. can be used.

Next, to explain the nonwoven fabric according to the present invention, for example, the nonwoven fabric is made by arranging fibers that do not have dyeability with the above dyes in a web or mat shape by an appropriate method, and then A sheet-like product made by bonding fibers to each other using an adhesive having dyeability can be used.

In the above, the fibers vary depending on the dye used, but examples include cotton, rayon, acetate, nylon,
Polyester, acrylic fiber, animal fiber, and other known fibers can be used.

In addition, in the above, the adhesive may vary depending on the dye used, but for example, polyvinyl acetate latex, polyvinyl chloride latex, (consisting of monomers such as methyl methacrylate, methyl acrylate, butyl acrylate) Emulsion adhesives such as acrylic latex, powder adhesives such as phenolic, vinyl, and acrylic resins, vinyl, cellulose acetate, acrylic, polyester, and polyamide fibrous hot-melt adhesives, etc. Others can be used.

FIG. 2 is a schematic plan view of the nonwoven fabric as described above.

In the figure, amount 4 is a nonwoven fabric, 5 is an adhesive for nonwoven fabric, and 6 is a fiber.

Next, in the above-mentioned present invention, a method of thermal transfer using the above-mentioned transfer sheet and non-woven fabric will be briefly explained. A and A are superimposed so that any patterned surface of the former is in contact with the surface of the latter, and then subjected to heating and pressure treatment using a heated hot plate or heated roll, etc., and then the above-mentioned transfer sheet 1 is peeled off. As a result, only the dye in the arbitrary pattern on the transfer sheet 1 is transferred to the nonwoven fabric as shown in the third figure, and the dye 7 is transferred only to the adhesive portions 5 arranged in the nonwoven fabric. A new synergistic pattern is formed when the ink is applied, and since only the dye is transferred from the transfer sheet and the binder that makes up the ink is not transferred, a transfer product 6 with a good texture can be obtained.

As described in detail above, in the present invention, decoration is performed by dyeing the adhesive portion distributed in the nonwoven fabric, so unlike when painting by printing, the texture is deteriorated by the binder transferred and fixed to the surface of the nonwoven fabric. (It is possible to produce painted non-woven fabrics with good texture.)

The above-mentioned present invention will be explained in more detail with reference to Examples below.

Note that "parts" in the examples are parts by weight.

Example 1 80 parts of ethyl cellulose (manufactured by Vercules, trade name: ethyl cellulose N7CP) and 100 parts of an oil-soluble dye (Sudan Blue ■, Cl-2883) were mixed into a mixed solution of xylene, butyl acetate, and butanol (mixing ratio 424:2). ) and sufficiently kneaded in a ball mill to obtain a blue ink composition.

Next, using the blue ink composition obtained above, a rose flower pattern was printed on bleached kraft paper using a gravure method to obtain a transfer sheet.

Furthermore, a rayon nonwoven fabric (Suncloth #1035 manufactured by Sanko Vilene Co., Ltd.) with fibers bonded by butadiene-acrylonitrile copolymer and the sheet-like material obtained above were stacked so that the surface of the former was in contact with the printed matter of the latter. Combine,
Place both of them as they are between the press plates of a transfer machine, and heat and press at 190℃ and 2kg/crlL for 6 hours.
The sheet was held for 0 seconds, then taken out, and the sheet-like material was peeled off from the nonwoven fabric to obtain a rayon nonwoven fabric with an extremely clear color tone, an elaborate and delicate rose flower pattern, and a good texture.

Example 2 In Example 1, a disperse dye (Kayalon Polyester Hink BSF manufactured by Nippon Kayaku Co., Ltd.) was added to the dye in the ink composition.
A transfer sheet was prepared in the same manner using C-l-Disperse Red 55), and heat transferred using an iron to a rayon nonwoven fabric (#1050 manufactured by Sanko Vilene Co., Ltd.) with fibers bonded with butadiene-acrylonitrile copolymer. A rayon nonwoven fabric having a pattern with a clear color tone without losing its texture was obtained.

Example 3 In Example 1, a disperse dye (Mitsui Chemicals Miketon Polyester Yellow 5G C) was added to the dye in the ink composition.
-I-Disperse yellow 5) to adjust the yellow ink, and print a multicolored butterfly pattern using the gravure method using the blue ink of Example 1 and the red ink of Example 2 to obtain a transfer sheet. Ta.

Thermal transfer was then carried out in the same manner as in Example 1 to obtain a rayon nonwoven fabric with a clear color tone and an elaborate multicolored butterfly pattern.

This nonwoven fabric maintained its base texture, and no dissolution of the colored material was observed in soapy water or vinegar.

Example 4 The transfer sheet obtained in Example 3 was applied in the same manner to a nonwoven fabric made of a viscose rayon web that was bonded by applying an adhesive (acrylic acid ester emulsion) in stripes about 5 mm wide at intervals of 1 crIL. Transcribed.

A clear striped multicolored line pattern was transferred to the adhesive.
