DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base fabric for a label for indicating quality and the like sewn on the back side of various kinds of clothing or inside pockets.

[0002]

2. Description of the Related Art A quality display label sewn on various types of clothing displays the material, cleaning suitability, size, etc. of the clothing. The quality of the clothing material and the like is recorded by printing on various types of printing means on a woven fabric (generally a tape-like fabric). In recent years, a thermal head method has been often used as the printing means. In the thermal head method, a thermal head having a predetermined portion heated is pressed against a print medium impregnated with the hot-melt ink, and the hot-melt ink at a predetermined portion of the print medium is melted. Is transferred to a woven fabric.

Therefore, when printing is performed using the thermal head method, if the base fabric has irregularities, ink may be transferred only to the convex portions, and ink may not be transferred to the concave portions. That is, a defective portion occurs in printing.
In particular, in the case of a label for indicating quality or the like, since the base fabric is made of a woven fabric, there are cases where unevenness is severe and clear printing cannot be performed.

[0004] For this reason, a microporous synthetic resin film or a nonporous synthetic resin film (hereinafter collectively referred to as a “synthetic resin film”) that easily absorbs ink is provided on the surface of a woven fabric. It has been practiced to provide the synthetic resin film to reduce the unevenness of the base cloth. By providing the synthetic resin film, the printing performance was improved, but it was still unsatisfactory. In other words, when the print is visually read, it is satisfactory to some extent. However, when the print is read optically, the read often becomes impossible. In recent years, barcode printing has been heavily used for merchandise management (mainly inventory management and quality control) in addition to quality labeling. Read the bar code display,
This is because the merchandise is sorted, sorted, or received / shipped.

[0005] In the case of a woven fabric, unevenness is more severe than that of a fabric made of a material such as paper. Therefore, even if a synthetic resin film is provided, it can be optically read. It is difficult to obtain smoothness. For this reason, attempts have been made to repeat the application of the synthetic resin a plurality of times to increase the thickness of the synthetic resin film to completely hide the irregularities of the woven fabric. However, repeating the application of the synthetic resin a plurality of times causes a new disadvantage that the production cost of the woven fabric is increased. Further, when the thickness of the synthetic resin film is increased, there is a drawback in that when sewing a label such as a quality indicator on a garment with a sewing machine, penetration of a sewing needle is not smooth and sewing efficiency is reduced.

[0006]

Therefore, the present invention improves the smoothness of the woven fabric itself to be used, so that it can be optically read even when the synthetic resin is applied in the conventional manner. It is intended to impart a smoothness to the base fabric, which enables printing of a certain degree.

As the material of the woven fabric used in the present invention, conventionally known polyester synthetic fibers and polyamide synthetic fibers are used.
Various synthetic fibers such as fiber and acetate semi-synthetic fiber can be used. In particular, among various synthetic fibers, polyamide-based synthetic fibers such as nylon 6 and nylon 66 can be suitably used. Since a polyamide resin is often used as a material of the synthetic resin film, a polyamide synthetic fiber having good affinity and adhesion to the synthetic resin film is used. The polyamide-based synthetic fiber may be a short fiber or a long fiber, but is generally preferably a long fiber. The reason for this is that the woven fabric obtained using long fibers has better smoothness than the woven fabric obtained using short fibers. Further, the tensile strength of the obtained woven fabric is also high. Various conventionally known structures can be used as the structure of the woven fabric. For example, taffeta,
Twill, satin, or the like is used, but it is particularly preferable to use taffeta. The reason for this is that, among the woven structures, taffeta has the highest smoothness, the highest tensile strength, and the lower weight.

[0009] The above-mentioned woven fabric has more severe irregularities on the surface than paper or synthetic resin film due to its woven structure. Therefore, this fabric is subjected to calendering. Calendering presses the fabric in the thickness direction by introducing the fabric between a pair of heated smooth rolls,
The protrusion on the surface is pushed into the recess. That is, the surface of the woven fabric is made smooth by moving the constituent fibers forming the convex portions of the woven fabric surface to the concave portions of the woven fabric surface. As conditions for this calendering, the temperature of the smoothing roll is about 150 to 160 ° C., and the linear pressure between the smoothing rolls is
It is preferably about 6 to 7 kg / cm ² .

[0010] Such a woven fabric having a smooth surface has a physical property such that the value of the air permeability measured by the Flange method of the air permeability test method specified in JIS L 1096 is 20 cc / cm ² / sec or less. There are many. Such low air permeability means that the constituent fibers are moving into the gap between the warp and the weft constituting the woven fabric. That is, the fibers forming the convex portions of the woven fabric are moving in the gap between the warp and the weft, which is generally a concave portion of the woven fabric, which means that the fabric is excellent in smoothness. . 20cc / cm air permeability
^If it exceeds ² / sec, the gap between the warp and the weft of the woven fabric,
That is, it is not preferable because there are concave portions and the smoothness is reduced.

As described above, a microporous or nonporous synthetic resin film is bonded to one or both surfaces of a woven fabric having a smooth surface. As a material of the synthetic resin film, a conventionally known material can be used. In particular, it is preferable to use a polyamide resin or a polyurethane resin. this is,
This is because polyamide fibers are often used as constituent fibers of the woven fabric, so that affinity and adhesion to the woven fabric are improved. As means for providing a microporous synthetic resin membrane,
A woven fabric is immersed in a solution in which a synthetic resin such as a polyamide resin and inorganic particles such as calcium carbonate are uniformly mixed. Specifically, the polyamide resin is replaced with calcium chloride /
The fabric is dissolved in a methanol-based mixed solvent, and the woven fabric is immersed in a solution to which a plasticizer, a weathering agent, and an antioxidant are appropriately added.
By this immersion, the mixed solution is applied to both sides of the fabric. Thereafter, the woven fabric coated with the mixed solution is introduced into a coagulation bath to coagulate the synthetic resin. After coagulation, the mixture is introduced into a washing bath, and the remaining mixed solvent is washed away. Then, fine pores are formed at the locations where the mixed solvent has been washed off, and a microporous synthetic resin film is formed. In the case of this dip coating means, the microporous synthetic resin film is bonded to both sides of the woven fabric. It is also possible to bond the membranes. The reason why the synthetic resin film is microporous is that when printed by the thermal head method, it easily absorbs the hot-melt ink,
This is for giving a cushion effect to the head and obtaining clear printing. As means for providing a non-porous synthetic resin,
The polyurethane resin solution may be applied with a coater or the like and dried.

The base fabric of the label for indicating quality etc. obtained as described above is generally cut into a tape shape so as to be easily printed by a thermal head system. The woven fabric to which the synthetic resin film is bonded may be subjected to a calendering process to be used as a base fabric of a label for indicating quality or the like. By this calendering, the surface of the synthetic resin film is smoothed, and the fabric and the synthetic resin film are tightly joined. Then, the quality and other indications of the materials of the clothing and the like are printed on the base cloth, and the indications become the quality and other indication labels. The quality label is used by being sewn on the back side of clothing or the inside of a pocket.

[0013]

As described above, the base fabric of the quality indicator label according to the present invention is manufactured using a woven fabric subjected to calendering. That is, since the surface of the woven fabric is excellent in smoothness, if a synthetic resin film is further bonded to this surface to obtain a base fabric, the smoothness of the base fabric surface is further improved. Therefore, when the quality of the material of the garment or the like is printed by the thermal head method or the like using the smooth base cloth having a small amount of unevenness, the printing becomes very clear with few defects. Therefore, print barcode, etc.
Even if the print is read by the optical reading means, there is an effect that erroneous reading and unreadableness are less likely to occur.

Further, since the surface of the woven fabric is smooth, it is less necessary to increase the thickness of the synthetic resin film to smooth the surface of the obtained base fabric. Therefore, there is an effect that the amount of the synthetic resin used and the number of times of applying the synthetic resin can be reduced, and the base fabric can be manufactured at low cost. Furthermore, since the thickness of the synthetic resin film can be reduced, when sewn a label such as a quality label using the base cloth to clothing, it is easy to sew, and there is an effect that sewing efficiency can be improved. .
