Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a method for transferring textile treatments, such as dyes, insect repellents, water repellents or smoothing agents, from printed or otherwise coated paper to textiles, In particular, it relates to a dye transfer process which has similarities to the process shown in British Patent No. 1,284,824 and to the process shown in British Patent Application No. 5,301,3772, which is an improvement on that patent's process.

According to the method of the British patent mentioned above, an acidic aqueous solution, for example an aqueous sulfamic acid solution, and a mixture of e.g.
Fabrics or animal fiber materials are pre-soaked using a dipping solution containing a printing thickening agent (stack) that is stable in acidic conditions, such as a rubbery derivative of cust bean, and then applied to paper. The dye of the printed color former is transferred to the above-mentioned fabric, etc.

The first feature of the present invention is that the fabric is not pre-impregnated with the subsoak solution, and instead the subsoak solution or its components other than water are applied to the print layer or other form of coating layer formed on the surface of the paper. It is to include.

A second feature is that the heat treatment necessary to transfer the dye of the print layer or other substance forming the coating layer to the fabric or the like is performed by high frequency heating.

It is desirable that the high-frequency heating be performed between two heating plates placed opposite each other in a closed container.

Further, the frequency used is preferably on the order of about 27 MHz.

When processing a long fabric in the form of a belt or roll, a method may be adopted in which the fabric is moved along a roller heated with high frequency.

The high frequency radiation may also be carried out using a tumble dryer or a conveyor type continuous dryer for clothing.

One embodiment of the method of the present invention is a method in which water, which is a component of the soaking solution, is pre-impregnated into the fabric by evaporation and condensation or other means.

Examples of practically convenient means include pressing a blanket or the like soaked with water onto the fabric, or rolling a roller made of foamed synthetic resin soaked with water over the fabric.

Other components of the subbing liquor, such as sulfamic acid, sulfuric acid or formic acid, and printing thickeners (stacking agents) are deposited and/or impregnated onto the aforementioned paper.

This treatment may be performed before or after applying the transfer ink to the paper.

However, it may be more economical to dissolve any acid in water and then mix it with alcohol and mix it with the transfer ink, or to disperse it directly in the ink's solvent and mix it with the ink.

Another embodiment of the method of the invention is to impregnate the paper with the required amount of water along with the other components of the soaking solution instead of pre-impregnating the fabric with water.

To use this method, it is necessary to use paper with appropriate water absorption properties, such as paper mixed with cotton fibers.

As a high-frequency heating device for heating a large number of fabrics simultaneously in a batch method, it is convenient to use a device that can accommodate multiple layers of fabric and printed paper alternately stacked on top of each other.

In addition, when the target material for transfer etc. is a knitted product, a mold may be used to keep it in a stretched state when stacking and heating it in this way.

The method of the present invention can be carried out regardless of whether the fabric is a simple sheet-like item or a clothing item, and the fabric material can be natural fibers such as wool or cotton, acrylic, etc.
Synthetic fibers such as polyester, polyamide, polyurethane, and dyeable polypropylene may be used, or a blend thereof may be used.

If necessary, it is also possible to transfer to both sides of a single piece of fabric at the same time.

The advantages of the method of the present invention are, firstly, that it is easier to carry out than previously known methods, and secondly, that the degree and time of heating are easier and more precise than those of conventional methods. It is something that can be adjusted.

Claims (1)

[Scope of Claims] 1. A water-excluding component of a chemical composition for priming containing an acidic aqueous solution and a textile treatment agent are included in a layer formed by impregnating or coating the surface of paper, and then the A method for adhering a chemical composition to a textile fabric, which comprises pressing the surface of the formed layer onto the textile fabric, and heating the paper and the fabric in that state with high frequency waves having a frequency of about 27 MHz. 2. Impregnating paper with a dye, coating the paper with a component of a chemical composition for undercoat, excluding water, consisting of dilute sulfamic acid acetic acid or formic acid and a thickening agent for printing, and applying the paper on a pre-moistened fabric. A method for attaching a chemical composition to a textile, which is characterized by pressing the textile and heating it with high frequency at a frequency of about 27 MHz.
