Description

[Detailed description of the invention] The present invention relates to an emboss transfer discharge printing method.

More specifically, the present invention relates to an emboss transfer discharge printing method in which a discharge printing agent or a colored discharge printing agent is transferred simultaneously with the embossing process.

In general textile printing technology, discharge printing is a method in which a paste containing a discharge dye (reducing agent and oxidizing agent) is printed on fabric that has been plain-dyed with a removable dye in advance, and the background color of that area is removed to create a pattern. .

Dyes that can be discharged with a discharge agent are called removable dyes, and dyes that cannot be discharged are called non-removable dyes.

In addition, a paste containing a discharge printing agent and a non-dischargeable dye that is not discharged with the discharge printing agent and has a different hue from the plain dyed releasable dye is printed, and at the same time as discharge printing, only that part is colored with the non-dischargeable dye to create a pattern. The method of attaching is also generally known as the colored discharge printing method.

Discharge printing methods are broadly divided into reduction discharge printing methods that use reducing agents and oxidation discharge printing methods that use oxidizing agents.

Reducing agents used as discharge printing agents include dechlorin (trade name, manufactured by BASF) and stannous chloride, and oxidizing agents include sodium chlorite and sodium hypochlorite.

Usually, dechlorin is used as a discharge printing agent for polyester fibers.
stannous chloride is used; for polyamide fibers discharge printing with dechlorin and colored discharge printing with stannous chloride is used; for regenerated cellulose fibers Rongarit (Hoechst, Inc.,
Commonly used natural fibers include Alparaite (Daiichi Pharmaceutical Co., Ltd., trade name), Hydrosulfide Conc (Ciba Geigy Co., Ltd., trade name), and Rongalite.

However, in general textile printing, embossing and discharge printing or colored discharge printing are performed separately, so there is a problem in synchronization between the embossed part and the discharge printed or colored discharge part.

That is, it is almost impossible to transfer a discharge printing agent or a colored discharge printing agent to the embossed recesses, or to accurately emboss the areas that have been discharged or colored discharged afterwards.

An object of the present invention is to provide a new method for simultaneously performing embossing and discharge printing or colored discharge printing, which was previously impossible.

According to the present invention, it is possible to provide a cloth having a new and beautiful pattern, which is made of a wide range of materials and subjected to embossing and discharge printing or colored discharge printing at the same location.

Fabrics that can be used in the present invention include synthetic fibers such as polyester, acetate, acrylic, and nylon, cellulose fibers, regenerated cellulose fibers, and fabrics made of blends thereof.

In the emboss transfer discharge printing method of the present invention, a transfer paper having a layer containing a discharge printing agent is laminated on the above-mentioned cloth (transferred cloth) that has been pre-dyed with a removable dye that is discharged with the discharge printing agent, and the embossing is done as a processing step. The present invention is characterized in that the discharge printing agent is simultaneously transferred to the transfer cloth, and the obtained transfer cloth is subjected to a steam heat treatment and then a soaping treatment, whereby embossing and discharge printing are performed on the cloth at the same time.

By mixing a non-dischargeable dye that is not discharged by the above-mentioned discharge printing agent into the layer containing the above-mentioned discharge printing agent, colored discharge printing can be performed at the same time as embossing.

The present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic cross-sectional view of a transfer paper 1 used in the method of the present invention.

The transfer paper base material 2 is printing paper such as art paper, printed paper, pure white paper, cellophane paper, acetate film, aluminum foil, or a laminated film of these.

The transfer paper 1 has a transfer resin layer 3 on a base material 2, and a layer 4 containing a discharge printing agent thereon.

The resin constituting the transfer resin layer 3 and the binder resin of the discharge printing agent are resins having similar properties, preferably the same resin, such as polyester resin, polyamide resin,
Thermoplastic resins with a softening point in the temperature range of approximately 50 to 250°C, such as maleic acid resins, vinyl resins, xylene resins, phenolic resins, ketone resins, acrylic resins, petroleum resins, and cellulose resins. is preferred.

Generally, it is preferable to perform a peeling treatment with silicone or the like on the transfer base material 2 before applying the transfer resin layer 3.

Discharge agents that may be used include the conventional discharge agents described above, such as dechlorin, stannous chloride, and the like.

Furthermore, the transfer resin layer may be omitted by appropriately selecting a binder resin for the discharge printing agent.

The layer 4 containing the discharge printing agent is preferably formed by a suitable printing method such as a gravure method or a screen method.

The thus obtained transfer paper 1 is stacked on a transfer cloth 5 as shown in FIG.

The layer 4 containing the discharge printing agent of the transfer paper 1 and the transfer cloth 5 must be stacked in the direction facing each other.

The transfer cloth 5 is pre-dyed with a dischargeable dye that is discharged with a discharge dye contained in the layer 4.

The laminated transfer paper 1 and transfer cloth 5 are transferred to the transfer cloth 5 by using a heated embossing roll to transfer the layer 4 containing the discharging agent only in the portions pressed by the convex portions of the roll to the transfer cloth 5, and at the same time, the embossing pattern is applied. Process.

For embossing, the processing direction is on the transfer paper 1 side as well as on the transferred cloth 5.
It may be set as desired.

Further, instead of the embossing roll, a plastic net having an uneven surface in a desired shape or the like may be placed on the transfer target cloth 5 side for transfer.

Thermal transfer conditions are approximately 100-250℃, approximately 1-25℃.
A pressure of 0 kg/crtt and a transfer speed of about 3 to 30 m/min are preferable, but instead of transferring the entire surface, the R1 embossing pattern is applied only to the part pressed by the convex part of the embossing roll. Conditions must be selected so that the discharge printing agent layer 4 is transferred only to the areas that have been removed.

FIG. 3 shows a schematic cross-sectional view of the transfer cloth 5 obtained by placing an embossing roll on the side of the transfer paper 1 and performing transfer and embossing as described above.

The transferred cloth 5 in the state shown in FIG. 3 is subjected to steaming treatment and then soaping treatment in the same manner as in general discharge printing technology.

The removable dye that has been pre-dyed by steaming is removed by the action of a discharging agent.

Further, the transfer resin layer, binder resin, etc. are removed by soaping treatment using water or a solvent.

In this way, as shown in FIG. 4, a cloth is obtained which has areas 6 where embossing and discharge printing have been applied in the same area.

It is also possible to use a transfer paper on which a layer containing a non-dischargeable dye which is not discharged by the discharging agent together with a discharging agent is formed in place of the above layer 4.

In this case, coloring with the non-removable dye occurs at the same time as the removable dye is decolorized by the steaming treatment, and the embossed discharge area 6 in FIG. 4 is colored and discharged at the same time as the embossing process.

The present invention incorporates the advantages of discharge printing or colored discharge printing, the advantages of the transfer printing method, and the advantages of the embossing technique to provide a beautiful and fashionable printed product that is unprecedented.

Moreover, according to this method, accurate synchronization between embossing and printing or color discharge printing can be obtained.

Therefore, compared to the conventional method in which embossing and discharge printing or coloring discharge printing are carried out separately, according to this method, it is possible to significantly reduce working time and costs.

Next, the present invention will be explained in more detail with reference to Examples.
