Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a fabric in which short hairs are flocked on the surface of paper, the flocked paper is layered on a cloth, and a heated mold is pressed to form a flocked shape in a desired pattern on the cloth. The present invention relates to a fabric processing method for forming an uneven pattern on the fabric and at the same time forming a flocked shape of a desired pattern.

A processing method is known in which a flocked paper is interposed on a cloth placed on a fixed plate and a heated mold is pressed to form a flocked shape of a desired pattern on the surface of the cloth.

That is, as shown in FIG. 2, the known method involves flocking short hairs 3 onto the surface of paper 1 via adhesive 2 to create flocked paper A.
A cloth 6 to be processed is placed on the fixed plate 4 with an insulating cloth 5 interposed therebetween as shown in FIG. The solid adhesive 7 is layered on top of the solid adhesive 7, and the flocked paper A is layered on top of it so that the flocked side faces the fabric 6 (the top and bottom of FIG. By pressing the cloth 6 through the flocked paper A, the short hairs 3 are separated from the paper 1 and the adhesive γ is melted, and the short hairs 3 are attached to the cloth 6 by the melted adhesive 7 and transferred, This is to form a flocked pattern on the surface of the cloth 6 in a desired pattern (for example, an A-shape) determined by the shape of the fixed adhesive 7.

In addition, in the figure, 9 is a press device.

By the way, according to the above processing method, the pressing part 8a of the heating mold 8 is a flat surface and has a large area, so the heating area is large and the transfer time is long, and the solid adhesive 7 is not used. Therefore, a process of molding the adhesive 7 and placing it is required, which makes the work complicated and increases the cost.

In addition, since the pressing surface 8a is a flat surface, it is not possible to form an uneven pattern on the cloth at the same time as pressing, and there is also a drawback that it cannot be used for napped fabrics because it presses the napped fabric and causes them to sag.

This invention provides that if a concave-convex pattern is formed on the suppression surface of a heating mold, the heating area becomes narrower and the transfer time can be shortened, and that the concave-convex pattern can be formed on cloth by the convex stripes of the concave-convex pattern, and the transfer time can be shortened. This is a fabric processing method that was developed by focusing on the fact that the adhesive for woolen paper can be melted and transferred to fabric.Next, this invention will be described based on the attached drawings showing an actual sister example. explain.

Note that the same symbols as above indicate the same thing.

First, the flocked paper A' according to the processing method of the present invention, as shown in FIG. Any material that can attach the short hairs 3 to the paper 1, melt it by heating, peel off the short hairs 3 from the paper 1, and re-adhere the peeled short hairs 3 to the cloth 6 may be used. Since it also acts as an adhesive to adhesive 6, it is thicker than adhesive 2 described above.

Furthermore, in order to facilitate the separation of the paper 1 and the short bristles 3, the surface of the paper 1 may be coated with a release agent to form a release paper.

Next, to explain the flocking method using the flocking paper A', as shown in FIG. A patterned fabric 12 that is easy to press and an elastic fabric 13 that has resilience are placed one after another, and the fabric 6 to be processed is placed on top of the patterned fabric 12 that is easy to press.
is placed thereon, and then a flocked paper A' is placed on top of it with the flocked side facing the fabric 6.

On the other hand, a mold 15 having an uneven pattern is attached to the lower surface of the high-frequency anode plate 14, and an electric heater is embedded inside the anode plate 16.

Note that an electric heater is also embedded in the cathode plate 11 as required.

When processing, the electric heater is energized and the high frequency power is turned on to heat the mold 15, and the press device 9
As shown in FIG.
is pressed against the cloth 6 through the intervening.

By this pressing, the cloth 6 is pressed by the heating mold 15 and pressed under high frequency treatment, and a pattern in which the concave and convex patterns of the mold 15 are reversed is formed on the surface of the cloth 6.

During this action, since the mold material 12 and the elastic material 13 are placed on the cathode paper 11, the pressing part (recessed part) by the protrusion 16 of the single heating mold 15 is pressed against the mold as shown in FIG. Fabric 12
In other words, the pressing portion sinks deeper into the cloth 6, forming a clear concave pattern, compared to the case of a rigid flat surface without the mold material 12 and elastic material 13.

Further, by pressing the flocked paper A' with the heated protrusions 16, the hot melt adhesive 10 on the pressed part melts and the short hairs 3 are peeled off from the paper 1, and the peeled short hairs 3 are melted. Adhere to cloth 6 with adhesive 10.

That is, the short hairs 3 are transferred to the concave pattern portion of the cloth 6.

If the height of the protrusion 16 of the mold 15 (t) in FIG. 4 is set to be approximately the same as or less than the thickness of the cloth 6, the flocked paper A' will only be applied to the concave portion of the cloth 6, as shown in FIG. Mold 1
The flat portion 17 of the cloth 6 is pressed against the rest of the cloth 6 (the convex pattern portion), and the short bristles 3 are adhered not only to the concave portions but also to the convex portions of the cloth 6.

That is, the pattern of the flocked paper A' can also be transferred to the cloth 6.

If there is a part of the flat part 17 on the cloth 6 that is not desired to be transferred, the mold 15 may be made such that that part is made into a part 18 recessed from the flat part 17, as shown in FIG.

By doing so, a pattern is formed on the cloth 6 by four parts: a concave part, a convex part, a flocked part, and a non-flocked part.

Although FIG. 5 shows the case where the cloth 6 is a flat cloth, it goes without saying that the above effect can also be obtained with a raised cloth as shown in FIG.

Also. In the above example, the pattern fabric 12 and the elastic fabric 13 were used, but if the height of the ridges 16 is set as above, it is possible to obtain the effect of flocking other than the four parts of the fabric 6 even if one or both of them are not present. I can do it.

If neither of the fabrics 12 and 13 are present, the height of the protrusion 16 shall be shorter than the shrinkage thickness of the fabric 6 due to pressing.

Furthermore, since the shape of the protrusions 16 remains as grooves in the mold material 12 even after the pressing is released, the recesses of the cloth 6 are further sunk in during the next pressing operation, and the recesses are formed more clearly.

Therefore, if a concave groove is formed in the fixed plate (anode plate) 11 that corresponds to the protrusion 16 and has the same planar shape, the concave portion of the cloth 6 pressed by the protrusion 16 will enter the concave groove, so that the above-mentioned The effect that the recessed portions are clearly formed can be obtained.

The above actual case shows the case where an electric heater and high frequency are used together, but instead of the electric heater, an oil heater, an electric (
Of course, the present invention can also be applied to the case where only an oil heater is used, or when only ultrasonic waves or high frequency (ultrasonic waves) are used instead of high frequency waves.

Further, the elastic fabric 13 in FIG. 4 can be used for transferring the fabric 6, that is, by transferring the fabric 13, the fabric 6 can be transferred.

In the actual case described above, the formation of an uneven pattern on the cloth 6 by heating and pressing with the heating mold 15 is performed at the same time, but it is also possible to simply transfer the short hairs 3 of the flocked paper A' onto the cloth 6. Of course.

That is, the effect can be obtained even with the cloth 6 in which no concave shape is formed by pressing.

At that time, the mold material 12 and the elastic material 13 will be removed.

Next, a method for flocking the cloth and fixing the appliqué to the cloth will be explained.

As shown in FIGS. 9 and 10, in the heating mold 15,
In addition to the flocking ridges 16 on the fabric 6, ridges 19 corresponding to the outer outline and drawing areas of the applique B are provided, and the heating mold 15 is pressed against the fabric 6 and the applique B as shown in the figure. As shown in FIG. 11, an uneven pattern is formed on the cloth 6, and the applique B is fixed to the cloth 6, and flocking is applied to the portions of the applique B and the cloth 6 where the flocked paper A' is pressed. You can obtain processed fabric.

That is, in the figure, it is possible to obtain a wide variety of processed cloths, such as the flower a having an appliqué pattern, the leaves having a flocked pattern, and the surrounding area having a background color of the cloth 6.

At that time, if you use a synthetic resin sheet for applique B,
The appliqué fabric can be melted and welded using the outer contour protrusion 19 as a cutting blade.

However, if the mold 15 touches the surface of the applique 8, there is a risk that the applique fabric B will melt, so as shown in FIG. The pressed state is as shown in the figure.

Therefore, in this case, the applique will not be flocked except for the outer ring line portion and the drawing line portion.

Furthermore, if the applique B is made of non-melting fibers such as natural fibers, it is necessary to interpose, adhere or coat a thermoplastic synthetic resin sheet on the back surface thereof.

Furthermore, instead of the synthetic resin sheet, applique B may be made of fibers with a high heat melting point on the front surface and fibers with a low heat melting point on the back surface, and both fibers are made of the same type of fiber such as acrylic fiber. You may.

If the applique B is made of a fabric whose surface is not melted by heat, the mold 15 can also be brought into contact with the applique surface, so that the height t' of the protrusion 19 shown in FIG.
If the thickness is set to be approximately the same as or less than the thickness of the applique fabric B, the flocked paper A' can be pressed against the surface of the applique B, as shown in the figure, and flocking can be applied to that surface.

In addition, in the method of processing the cloth to which the appliqué B is fixed, as in the above-mentioned embodiment, the elastic cloth 12 and the pattern cloth 1 are
By using either or both of 3, or by forming grooves corresponding to the protrusions 19 on the cathode plate 11 (fixed plate), the effects of these configurations can be obtained in the same way as described above.

It goes without saying that the heating means may be an electric (oil) heater, a high frequency, or a combination of both.

Furthermore, a method for fixing an appliqué using the above processing method will be explained.

As shown in FIGS. 12 and 13, a protrusion 1 corresponding to the outer contour line portion and drawing line portion of the appliqué is placed on the heating mold 15.
9, and a heating mold 15 with flocked paper A' interposed.
Press on applique B.

This suppression causes the appliqué B to be welded to the cloth 6, and at the same time, the flocking is caused to occur in the suppressed portion.

As shown in FIG. 13, if the height t" of the protrusion 19 is approximately the same as or less than the thickness of the applique B, it can be Hair transplantation is possible.

In this case as well, a stepped portion may be formed on the flat surface for a portion where hair transplantation is not desired.

Furthermore, if the protrusion 19 corresponding to the outer contour line portion is shaped like a blade, fusing and welding can be achieved.

In addition, in the present invention, when flocking is carried out on the front and back sides of the cloth 6, the back side may be processed continuously after the front side is processed.

As described above, according to the fabric processing method of the present invention, flocked paper is formed by flocking short hairs on the surface of the paper via a hot melt adhesive, and the short hairs are attached to the processed surface of the cloth placed on a fixed plate. Flocked paper is stacked with the flocked side on the right side, and an uneven pattern heating mold is pressed onto the fabric with the flocked paper interposed, and the hot melt adhesive of the flocked paper in the pressed area is applied by the convex stripes of the heating mold. The short hairs were melted and peeled off from the paper, and the peeled short hairs were bonded to cloth using melted hot melt adhesive, so that the short hairs in the ridged pattern of the heating mold were transferred to the cloth. , there are fewer suppressed parts, less heating energy is required, and the flocking process can be completed in a short time.In addition, unlike conventional fixing adhesives are not used, it is possible to shorten work time and reduce costs. It is possible to reduce the

In addition, since it is a partial press, it can also be flocked to napped fabrics.

Furthermore, if you simultaneously form an uneven pattern on the cloth,
This has the effect of making it possible to inexpensively obtain a processed cloth having a pattern due to unevenness and flocking.
