Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel textured patterned fabric and a method for manufacturing the same, and more specifically, an elastic body is sandwiched between an upper fabric and a lower fabric, and these are integrally patterned with sewing thread. The present invention relates to an uneven patterned cloth which is sewn and bound by a heat-meltable synthetic resin impregnated with at least an upper fabric or an elastic body with the sewing thread, and a method for manufacturing the same.

Traditionally, textured patterned fabrics have been firstly made by sandwiching an elastic body between an upper fabric and a lower fabric and sewn together in a pattern using sewing thread, and secondly by fabrics made from an upper fabric. By partially applying adhesive in a pattern to the elastic body sandwiched between the top fabric and the bottom fabric, and sandwiching this between the top fabric and the bottom fabric, compressing it with a heating roll, etc., and then releasing the compression, the inside of the elastic body is A textured pattern fabric is known in which an adhesive is cured while an elastic body is compressed, and an upper fabric or a lower fabric is partially adhered to the elastic body with the adhesive.

The quilted fabric is sewn with an elastic body compressed, and after sewing, the compression is released, and the part sewn with sewing thread is left compressed to form a recess, and the other parts are sewn with the elastic body. The second uneven pattern fabric is made by applying adhesive partially to the elastic body in a pattern, sandwiching the elastic body between the upper fabric and the lower fabric, and heating it. By compressing with a roll and then decompressing,
In the areas where the adhesive is present, the adhesive is cured while being compressed to form concave portions, and in other areas, the elastic body is restored to form convex portions.

However, conventional quilted fabrics have the disadvantage that when the sewing threads are cut, they are continuously removed, the fraying spreads, and the uneven pattern formed by the sewing threads disappears. It was difficult to cut and process it into any shape.

In addition, in the case of the second textured fabric, unlike the quilted fabric, sewing thread is not used, so there is no problem of thread removal due to cutting of the sewing thread or the loss of the uneven pattern due to the cutting of the sewing thread, and furthermore, unlike the quilted fabric, there is no need to remove the stitches or remove the uneven pattern. It has the advantage of being free to cut and process without cutting the sewing thread or losing the pattern due to thread removal when cut into the shape of It had the disadvantage of being lacking in

By combining a quilted cloth and a second uneven pattern cloth, the present inventors can obtain an uneven pattern cloth that does not lose its uneven pattern even when the sewing thread is cut or removed, and can be cut. I thought this might be the case, so I tried the following method.

Adhesive is applied partially to the elastic body in a pattern, this is sandwiched between the upper fabric and the lower fabric shaft, compressed with heated rolls, etc., and then the compression is released to release the adhesive in the elastic body. The elastic body is cured in a compressed state, and the upper fabric and lower fabric shaft are partially adhered to the elastic body using the adhesive to create a concave-convex pattern cloth, and sewing thread is applied along the concave portions of the concave-convex pattern cloth. sew.

However, the concave-convex pattern fabric obtained by this method is simply sewn over the concave portions of the previously formed concave-convex pattern fabric, and has the disadvantage that the sewing threads may be pulled out due to cutting, impairing the appearance. there were.

Moreover, the manufacturing method also had the disadvantage of requiring double labor and increasing costs, making it impractical.

As a result of intensive research, the present inventors have solved the drawbacks of conventional textured patterned fabrics such as quilted fabrics, and even if the sewing threads are cut, they will not be continuously removed, and To provide an uneven pattern cloth which does not cause the uneven pattern formed by sewing thread to disappear and which can be cut and processed into any shape, and at the same time to provide a method for manufacturing such an uneven pattern cloth. It is something.

That is, in the present invention, the elastic body 3 is sandwiched between the upper fabric 1 and the lower fabric shaft 2, and the upper fabric 1, the lower fabric shaft 2, and the elastic body 3 are sewn together in a pattern using the sewing thread 4. The first invention relates to an uneven patterned cloth in which the sewing thread 4 is bound by a heat-meltable synthetic resin 5 impregnated into at least one of the upper fabric 1, the lower fabric shaft 2, or the elastic body 3. At least one of the upper fabric 1, the lower fabric shaft 2, and the elastic body 3 is impregnated with heat-meltable synthetic resin, the elastic body 3 is sandwiched between the upper fabric 1 and the lower fabric shaft 20, and the sewing thread 4 is used. The upper fabric 1, the lower fabric shaft 2 and the elastic body 3 are sewn together in a pattern,
Next, by heating, the heat-meltable synthetic resin impregnated into either the upper fabric 1 or the lower fabric shaft 2 or the elastic body is melted, and by subsequent cooling, the sewing thread 4 is coated with the heat-meltable synthetic resin at least into the upper fabric. 1 or a second invention relating to a method for manufacturing a concavo-convex pattern cloth characterized in that it is bound to either the lower cloth shaft 2 or the elastic body 3.

As the upper fabric 1 and the lower fabric shaft 2, commonly used woven fabrics, knitted fabrics, non-woven fabrics, etc. can be used.

The upper fabric 1 is preferably made of a durable material since it will be exposed on the outer surface when the uneven patterned fabric of the present invention is used as a shoe cover or clothing.

The lower cloth shaft 2 is made of a material that has excellent abrasion resistance because it is constantly subjected to friction by feet and the human body when the uneven patterned cloth of the present invention is used for shoe coverings or clothing, and also has excellent moisture absorption to absorb sweat. preferable.

As the sewing thread 4, commonly used natural fibers or synthetic fibers can be used.

Specific examples of sewing thread 4 include vegetable fibers such as cotton and linen;
Yarns made of animal fibers such as wool and silk, regenerated artificial fibers such as cellulose fibers and protein fibers, semi-synthetic fibers, and synthetic fibers such as polyester fibers and polyurethane fibers can be used.

As the elastic body 3 used in the present invention, cotton, actinic radiation synthetic resin foam, rubber sponge, feather, etc. can be used.

As the synthetic resin foam, commonly used materials such as vinyl chloride foam and polyurethane foam can be used.

The synthetic resin foam or rubber sponge may have a closed-cell structure or an open-cell structure, but open-cell structures are more preferable because they have air permeability.

As heat-meltable synthetic resins used in the present invention, polyamide resins, polyethylene resins, polystyrene resins, polyvinyl chloride resins, polyvinylidene chloride resins, polyacrylic resins, polyvinyl alcohol resins, etc. can be used.

Note that heat-meltable synthetic resins also include what is generally called thermoplastic rubber.

To explain the second invention in more detail, at least one of the upper fabric 1, the lower fabric shaft 2, or the elastic body 3 is impregnated with heat-meltable synthetic resin, and these are sewn together in a pattern with sewing thread. However, when an elastic body is impregnated with a heat-meltable synthetic resin, the entire thickness of the elastic body may be impregnated, or only the surface layer portion of the elastic body may be impregnated.

When impregnating the upper fabric 1 or the lower fabric 2 without impregnating the elastic body with the heat-meltable synthetic resin, it is preferable to impregnate the lower fabric 2 rather than the upper fabric 1.

This is because if the upper fabric is impregnated with a heat-meltable synthetic resin, the feel of the upper fabric may be impaired.

When imparting waterproof properties to the exposed top fabric, it is preferable to impregnate the top fabric with a heat-meltable synthetic resin.

Furthermore, in the present invention, a backing cloth may be adhered to the lower cloth side of the obtained uneven pattern cloth.

By adhering the lining fabric, it is possible to prevent the sewing thread appearing on the lower fabric side from being cut.

As mentioned above, in the textured patterned fabric of the present invention, the sewing thread is bound to at least the upper fabric, the lower fabric, or the elastic body by the heat-meltable synthetic resin, so even if the sewing thread is cut, the sewing thread remains continuous. The thread pattern can be maintained for a long period of time because the stitches will not be removed and the tangles will not spread.
