Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to printed composite fabrics which are mainly used in non-clothing fields such as bags and other bags, awnings, tablecloths, and curtains, and which are also used in the clothing field. Specifically, the present invention relates to a method of manufacturing a composite cloth in which a colored pattern is printed on one side of the cloth and a resin layer is provided on the other side.

[Prior art]

Traditionally, resin-lined composite fabrics with colored patterns, yarn-dyed patterned woven and knitted fabrics using colored yarn, and print-dyed woven and knitted fabrics or non-woven fabrics have been used for the above-mentioned purposes. It is manufactured by a method in which a layer of resin such as vinyl chloride or rubber is later provided on the back side by laminating or coating.

As a result, ■Distortions such as diagonal, curved, meandering, etc. are likely to occur in the yarn-dyed and printed patterns on the fabric surface. ■Therefore, in striped and checkered patterns, which are in relatively high demand, pattern distortions are easily noticeable, resulting in a high defect rate. ,■ Momentum patterns are limited to those that are hard to grow in quantity and do not have noticeable distortions.■For this reason, it is difficult to switch production in response to changes in color and pattern trends and sales, and it is difficult to increase inventory. This can easily lead to prolonged out-of-stock items,
■ Conventional manufacturing methods have had the problem that the costs of yarn dyeing and print dyeing are high, and production costs are unavoidable due to risks such as scrapped defect rates and increased inventory. .

[Purpose of the invention]

The present invention is based on the fact that resin-backed composite fabrics with colored patterns do not require high washing fastness or sublimation fastness for dyeing, unlike ordinary clothing fabrics. This was done as a result of our focus on dyeing, and the cost of dyeing is low, there is no pattern distortion, and it is easy to change production in response to color and pattern trends, thereby reducing defective rates and increases in inventory. The present invention provides a method for manufacturing a printed composite fabric that eliminates the problems and can significantly reduce production costs.

[Structure of the invention]

The present invention is a color that consists of an ink composition whose main component is a coloring agent that has the property of providing a resin layer on one side of white or plain color cloth and then transferring it to the other side by phenomena such as melting, evaporation, and sublimation. A method for producing a printed composite fabric, characterized in that a color pattern is thermally transferred using a transfer sheet having a pattern.

In other words, the present invention adopts a thermal transfer method that does not require washing, desizing, drying, etc. for dyeing to give a colored pattern to the cloth surface, so that the dyeing can be carried out after lining the cloth with a resin layer. This has achieved the aforementioned purpose.

As the white or colored plain fabric in the present invention, a white or colored plain fabric that is conventionally used for non-clothing or clothing is used. That is, a white or plain dyed fabric of woven or knitted fabric or nonwoven fabric made of natural fibers, synthetic fibers, recycled fibers, etc. is used.

Then, the resin layer provided on one side of the cloth is laminated by coating a resin liquid with a roll coating method, knife coating method, etc., or by rolling or heat-sealing a resin sheet using a solvent or adhesive. provided by a method etc.

This resin layer may contain unsaturated materials such as polyester resin, polyurethane resin, polycarbonate resin, polyamide resin, acrylic acid, methacrylic acid, iconic acid, fumaric acid, maleic acid, etc. Carboxylic acids or ester derivatives of these unsaturated carboxylic acids, 2) IJ derivatives, or gastric acid amide derivatives, vinyl chloride, vinylidene chloride, vinyl acid, styrene vinylpyrrolidone, vinyl methyl ether,
Homopolymers of various vinyl monomers such as butadiene, ethylene, and propylene, or copolymers thereof, melamine resins, epoxy resins, silicone resins, etc. may be used alone or in mixtures. In addition to the above resins, in order to impart flexibility and electrical properties to the composite fabric, heavy or light calcium carbonate, kaolin, talc, clay, titanium white, mica, bentonite, calcium silicate, Fillers such as diatomaceous earth, crushed sand, magnesium carbonate, pallite, and water-containing aluminum are used. Furthermore, in addition to the above resin and filler, a foaming agent and an antifoaming agent may be added as necessary.

Additives such as dispersants, emulsifiers, thickeners, stabilizers, silicone oils, waxes, and colorants are used.

That is, to form a resin layer on one side of the cloth, a resin solution prepared by adding appropriate fillers and additives to an aqueous or solvent-based solution, emulsion, or suspension of the resin, or
Suitable for the hot molten state of the resin (5) Use a resin melt to which fillers and additives have been added, and apply it directly to one side of the cloth by roll coating or knife coating to coat the resin. Either by solidifying, or by forming a resin sheet in advance with or without a release sheet, and then applying the resin sheet using a solvent, a contact agent, or by thermal fusion.
It is done by gluing it to one side of the fabric. Such a method of forming a resin layer on one side of cloth is conventionally known. In addition,
It is preferable to use a foamed resin layer as the resin layer from the viewpoint of drapeability and cushioning properties of the resulting composite fabric, and the foaming may be obtained by a method using a foaming agent or by mechanical stirring. , or even one obtained by gas blowing. Considering the strength, uniformity, and density of the resin layer, the foamed state has an apparent volume of 2 to 2.
Preferably, it is 3.5 times as large. However, it is preferable to form the resin layer by a coating method rather than by a dry lamination method.

Cloth e with a resin layer provided on one side as described above
Colored patterns are printed on the other side of the X by transfer using phenomena such as melting, evaporation, and sublimation, as described in, for example, Japanese Patent Publication No. 47-44054 and Japanese Patent Application Laid-Open No. 49-12917. This is carried out using, for example, an apparatus such as that shown in FIG. 1 or 2, using a transfer sheet having a colored pattern made of an ink composition containing a coloring agent having the property of causing a colorant as a main component.

FIG. 1 is a partial side view showing a state in which transfer printing is performed in a batch manner by a transfer press machine, and FIG. 2 is a schematic side view showing a state in which transfer printing is performed continuously by a continuous transfer machine.

In Fig. 1, 1 is a lower plate, 2 is a hot pressing plate, an undersheet 3 is placed on the lower plate 1, and a composite fabric 4 is placed on top of it with the cloth 4a on top and the resin layer 4b on the bottom. The color pattern 5a of the transfer sheet 5 is stacked on top of the transfer sheet 5 with the side with the color pattern 5a facing down, and is pressed and heated with the hot pressure plate 2 from above. is transferred and printed on the cloth 4a of the composite cloth 4. Here, under seat 3
is used to prevent the resin layer 4b of the composite cloth 4 from adhering to the lower plate 1, and is made of paper whose surface has been smoothed by super calendering, polyamide resin, Known sheets with good mold releasability, such as paper whose surface has improved mold releasability by vapor deposition of ethyl cellulose resin, silicone resin, or aluminum, or polyester film, are used. The conditions for heating and pressing by the hot pressing plate 2 are a temperature of 80 to 250° C., depending mainly on the type of ink composition of the thermal transfer sheet 5.

Pressure of 50f/cIn2~20Ky/Crn2 and 30
A heating and pressing time of ~90 seconds is used.

In FIG. 2, a continuous sheet-like composite cloth 4 passes through a guide roller and is placed on the surface of a heat roller 6 rotating in the direction of the arrow.
The supplied composite fabric 4 is pressed so as to be in close contact with the surface of the heat roller 6 by a presser belt 7 made of heat-resistant felt or the like on the surface of the heat roller 6, and the composite fabric 4 is An undersheet 3 is fed between the cloth 4 and the presser belt 7, and a transfer sheet 5 is placed between the cloth 4a of the composite cloth 4 and the surface of the heat roller 6, on which the color pattern 5a is provided. The cloth is fed in with the cloth facing toward the cloth 4a. While the composite cloth 4 is rotating in contact with the surface of the heat roller 6 in this way, the color pattern 5a of the transfer sheet 5 is transferred to the composite cloth 4.
is transferred to the cloth 4a. Then, the transfer sheet 5 that has completed the transfer is wound up on the take-up shaft 8, and the under sheet 3 is also taken up when the presser belt 7 is separated from the composite fabric 4.
It is wound up on the winding shaft 9. Moreover, the composite cloth 4 to which the colored pattern 5a has been transferred is housed in a can in the illustrated example.

The undersheet 3 used in this case is also the same as the undersheet 3 in FIG. 1, and the undersheet 3 has the surface of the lower board 1 in FIG. It can be omitted if it does not exhibit adhesiveness to resin J@4b. Moreover, it goes without saying that the composite cloth 4 shown in FIG. 2 may be unwound from a rolled state and wound onto a winding shaft.

Furthermore, instead of the presser belt 7, a large number of press rollers may be used. The heating and pressure conditions for such continuous transfer are also appropriately set as in the example (9) of FIG. 1, and such a transfer method itself is conventionally known.

〔Effect of the invention〕

However, the present invention employs the above-mentioned thermal transfer dyeing method, that is, a dyeing method that does not require washing, desizing, drying, etc., so that it is possible to first provide a resin layer on the composite fabric and dye it later. As a result, the printed composite fabric can be quickly provided in response to demand without distortion of the color pattern, which is an excellent result. Printed composite fabrics obtained by the method of the present invention, bags such as bags, awnings, and tablecloths.

Although it is suitably used in non-clothing fields such as curtains, it can also be used satisfactorily in clothing fields where washing with water, ironing, etc. are not necessary.
