Abstract

PROBLEM TO BE SOLVED: To provide a method for imparting various and natural crepe state crape patterns to a cloth without harming its touch feeling. SOLUTION: This method for craping of a cloth is provided by applying a head shrinkable film on one side surface of the cloth, heat-treating and then peeling the heat shrinkable film off for leaving wrinkles produced on shrinking the film. Also by printing a printing paste in a pattern on the cloth, drying and then applying the heat shrinkable film on it for making that the crapes hardly are produced in the printing paste-printed part, or after applying the heat shrinkable film on the one side surface of the cloth and then by performing a flock processing on the other side surface of the cloth, it is possible to obtain products richer in designing property.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of subjecting a fabric to a novel design of graining.

[0002]

2. Description of the Related Art As a method of embossing a cloth, a method of heating and pressurizing the cloth with an embossing roller, or printing a paste on a heat-shrinkable cloth and then heat-treating the paste, is used to print the paste. A method is known in which the printed portion is not heat-shrinked, and only the other surface is heat-shrinked to finish the printed portion in a swollen state. However, there is a limit to the process, and a forced unevenness process is required, so that a product with a natural feeling cannot be obtained. Furthermore, although the latter can form various patterns by printing, the fabric itself is thermally shrunk, so that the texture of the printed pattern portion and the other portions are different, and a crepe-like grain pattern is obtained. It was difficult.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a natural crepe-like grain pattern can be imparted to a fabric without impairing its feeling, and a wide variety of crepe patterns can be obtained. It is an object of the present invention to provide a method capable of performing such operations.

[0004]

Means for Solving the Problems The present inventor attaches a heat-shrinkable film to one side of a fabric, heat-treats the heat-shrinkable film at a temperature at which the heat-shrinkable film shrinks, and peels off the heat-shrinkable film from the fabric. As a result, it has been found that a fine grain pattern can be formed on the fabric, and the present invention has been completed.

[0005] This method does not heat shrink the fabric itself, but heat shrinks the film adhered to the fabric, so that the fabric adhered thereto has fine wrinkles accompanying the heat shrinkage of the film. It is based on the fact that it enters. Therefore, the fabric itself does not cause a change in the thickness or the like, so that a very natural graining process can be performed.

In this method, a water-soluble glue is printed in a pattern on at least one of the front and back sides of the fabric, dried, and then the heat-shrinkable film is adhered to one surface of the fabric, so that the printed pattern portion is formed. The shrinkage of the heat-shrinkable film is restricted, the printed pattern portion of the fabric is kept relatively flat, and the non-printed portion has a fine grain pattern (wrinkle pattern). You can get a pattern.

In this case, since the water-soluble glue can be removed by washing with water after removing the heat-shrinkable film, the fabric has the same feeling as before the processing, but has a very decorative grained fabric. It can be. In addition, by adding a dye to the water-soluble paste, it is possible to obtain a delicate processed cloth which has not been present but has a change in color as well as a grain pattern.

After adhering a heat-shrinkable film to one side of the fabric, a pattern may be applied to the other side of the fabric with a water-soluble glue, followed by drying and heat treatment. Since even a thin cloth is supported by a film in a flat sheet shape, any of various printing methods can be used efficiently.

Furthermore, in the present invention, after adhering a heat-shrinkable film to one surface of the fabric, an adhesive is placed in a pattern on the other surface of the fabric and subjected to flocking (flocking), or to a method such as foiling. After the decorative piece is bonded or printed with a water-insoluble resin (which may contain a pigment or the like), the heat treatment may be performed. In this case, a floc pattern, a foil pattern, a resin pattern, or the like may be used. On the other hand, it is possible to obtain a very nice processed cloth which cannot be considered by other methods of having crepe-like wrinkles. Needless to say, the cloth may be printed with a water-soluble paste before the heat-shrinkable film is attached.

The fabric used in the present invention may be any of a woven fabric, a knitted fabric and a non-woven fabric. The type of fiber used is not particularly limited, and may be a blended product or a mixed woven fabric. It is preferable to use a fabric containing a synthetic fiber capable of fixing the fiber. In order to obtain a crepe fabric having a good feeling, it is preferable to use a thin cloth such as georgette, gauze, gauze or the like.

As the heat-shrinkable film, it is preferable to use a film which shrinks by 10% or more, especially 20% or more by heat treatment. What is commercially available as a so-called shrink film may be adhered onto a cloth via a thermoplastic resin. For example, a biaxially-stretched heat-shrinkable plastic film having a back surface processed with a hot-melt resin may be used as a cloth. It may be thermally bonded on top.

In the present invention, the heat treatment conditions after the heat-shrinkable film is adhered to the cloth may be any conditions as long as the heat-shrinkable film is shrunk. It is preferable to set the conditions for heat setting.

[0013]

Next, the present invention will be described in more detail with reference to examples. Example 1 In this example, a biaxially stretched polypropylene film in which a water-soluble glue was printed in a web shape on one side of a fabric (a georgette made of polyester), dried, and then provided with a hot melt resin layer on the back side Was passed through a hot roll at 120 to 140 ° C. so that the hot melt resin was in contact with the other surface of the fabric, and the polypropylene film and the fabric were adhered. Thereafter, a laminate of the fabric having a web-like printed pattern on the back surface and the polypropylene film is heat-treated at about 170 ° C. in a non-tensed state, that is, in a free state, to thermally shrink the polypropylene film, and at the same time, After heat setting of wrinkles of the fabric caused by heat shrinkage, the polypropylene film was peeled off, and then the water-soluble sizing agent was washed away from the fabric. The resulting product was a crepe-like fabric having a linearly complex and crumpled texture.

Example 2 A water-soluble glue was printed in a spider web on one side of a fabric (georgette made of polyester), dried, and then dried on a surface on which the water-soluble glue was printed. A polypropylene film was adhered in the same manner as described above, and then an adhesive was printed in a pattern on the other surface of the fabric, and a floc process was performed on which a short fiber was electrodeposited. At this time, although the cloth was a thin cloth, it was lined with a film, so that very high quality flocking could be performed. After that, the product obtained by peeling the film is very rich in design, with a velvety floc pattern as a flying pattern on a crepe-like fabric with a complicated and crimped texture It became.

Example 3 Large and small strip patterns were printed on one side of a cloth (polyester gauze) using two types of printing pastes (using a water-soluble glue) containing a light and dark blue disperse dye. After drying, Example 1
A biaxially stretched propylene film was adhered in the same manner as described above, and after heat treatment, washed with water to remove the printing paste. The obtained product had a flat design with light and light blue strips, and the entire periphery thereof was finely grained.

[0016]

According to the present invention, only by using a heat-shrinkable film, a crepe-like pattern (a variety of patterns such as those obtained by ripple processing and other wrinkle processing) can be easily and naturally applied to a fabric. (Including a grain pattern). In addition, a wide variety of crepe patterns, which have not been obtained conventionally, can be obtained by using a printing method, a flocking method, a foil processing method, and the like in combination.
