Abstract

PURPOSE: To obtain a cloth tape which is useful as a base cloth for adhesive plaster or care labels for clothes, as the cloth can be clean-cut with high accuracy with scarce yarn frays, by admixing binding fibers to weaving fibers and using them as a weft and subjecting the woven fabric to fusing treatment. CONSTITUTION: Fibers and binder fibers are mix-spun or combined into filaments and a woven fabric is made using the spun yarns or filaments as a weft. Then, the fabric is heat-treated at a temperature higher than the melting point of the binder to fuse the weft and warp. The melting point of the binder component is lower than that of the weaving yarns, and the fusing treatment can be effectively done, when a binder having a clear crystalline melting point such as an ε-caprolactone-copolymerized polyester is used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fabric tape having an excellent anti-raveling property.

[0002]

2. Description of the Related Art Conventionally, two types of cloth tapes have been provided: one that is woven and knitted in a width to be used and one that is woven and knitted in a wide width and then cut into a width to be used. The former is woven and woven by a special ultra-narrow weaving machine or ultra-narrow knitting machine, and is used for decorative ribbons for packaging and the like, and has the advantage that it does not cause thread fraying because it has an ear structure. There is a drawback that the cost is high due to the poor property. The latter is used after being knitted and woven into a width similar to that of a general wide cloth, and then cut into a width according to the application, and is used as a base cloth for gum tape, a base cloth for adhesive plasters, a care label for clothing, etc. When cutting into a predetermined width, there is a problem that it is difficult to accurately cut into a predetermined width due to the elasticity and flexibility of the cloth.
In addition, there is a problem that thread fraying is more likely to occur than the cut portion. In order to avoid these problems, after the knitting and weaving, the yarns are bonded by resin treatment to suppress the stretchability of the fabric and cut into a predetermined width, or when the material of the cloth tape is thermoplastic synthetic fiber, the ears For example, a melt-cutting method that prevents fraying of the yarn by fusing is used. However, adding a process of resin-treating the material leads to an increase in cost, and when the melt cutting method is adopted, only the ears of the cutting part are hardened, or only the ends are melt-bonded. The current situation is that problems such as fraying still remain.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cloth tape having good cutting accuracy and less likely to cause thread fraying.

[0004]

The present invention achieves the above object and has the following configuration. That is, in the present invention, a mixed yarn or a mixed yarn of a textile fiber and a binder fiber having a binder component having a melting point lower than that of the textile fiber is used as at least a weft yarn, and the warp yarn and the weft yarn are fused by the binder component. The subject is a cloth tape characterized in that

The present invention will be described in detail below. In the present invention, the textile fiber is a fiber used for ordinary textiles, such as natural fiber such as cotton, hemp, wool and silk, regenerated fiber such as rayon, semi-synthetic fiber such as acetate, polyester, nylon, acrylic, It refers to synthetic fibers such as polypropylene and vinylon, and these short fibers or long fibers can be used depending on the intended use.

The binder fiber used in the present invention is a fiber having a binder component having a melting point lower than that of the above-mentioned textile fiber. As the binder component, any polymer having a melting point lower than that of the above-mentioned textile fiber may be used, and various polymers such as polyester-based polymer, polyamide-based polymer and olefin-based polymer can be used. The melting point of the binder component is 30 ° C above the melting point of the textile fiber so that the workability during heat treatment of the fabric and the physical properties of the textile fiber are small.
It is preferably lower than the above, and for a textile fiber whose melting point is not clear, a polymer having a melting point lower than the softening point temperature or the decomposition initiation temperature may be used as a binder component.

As the binder component, it is preferable to select and use a polymer having good adhesion to the above-mentioned textile fiber, and it is convenient to use a low melting point polymer similar to the textile fiber. For example, when polyester is used as the textile fiber, it is preferable to use a low melting point polyester obtained by copolymerizing one or more dibasic acids or their derivatives with one or more glycols. Examples of dibasic acids include terephthalic acid, isophthalic acid,
Aromatic dibasic acids such as phthalic acid, P-oxybenzoic acid, 5-sodium sulfoisophthalic acid and naphthalenedicarboxylic acid, alicyclic dibasic acids such as oxalic acid, adipic acid, sebacic acid, azelaic acid and dodecanedicarboxylic acid And the like. Examples of glycol include ethylene glycol,
Diethylene glycol, triethylene glycol, propane diol, butane diol, pentane diol, hexane diol, neobenzyl diol P-xylylene glycol and the like can be mentioned.

In addition, ethylene terephthalate units and /
Alternatively, an ε-caprolactone copolymerized polyester obtained by copolymerizing ε-caprolactone with a butylene terephthalate unit can also be preferably used. The ε-caprolactone copolyester has 3 to 80 ε-caprolactone units.
Mol% copolymerized polyester with a crystal melting point of 100 ° C
The above is desirable. When the proportion of ε-caprolactone units exceeds 40 mol%, the elastomer becomes elastic, and a tape having a relatively soft texture can be obtained even if the fibers are fused after heat treatment. If the ε-caprolactone unit is less than 3 mol%, the adhesive strength is not sufficient, and the thread fraying prevention property after cutting becomes insufficient, and if it exceeds 80 mol%, the melting point becomes too low and the resin softens during use.
It is not preferable because it sticks in a process other than heat treatment during finishing.

The binder fiber may be a fiber composed of only the binder component, but the composite fiber in which the binder component forms the whole surface or a part of the surface of the single fiber has the spinnability and the spinnability. It is preferable from the point. As a composite form, as shown in FIG. 1, a core-sheath type, a side-by-side type, a sea-island type, a split fiber type, etc., in which a polymer having a high melting point similar to that of the binder component is used as the core component 1 and a binder component is used as the sheath component 2 are used. Can be mentioned.

The fabric tape of the present invention comprises the above-mentioned mixed yarn of short fibers of the textile fiber and binder fiber or the mixed yarn of the respective long fibers, at least as the weft of the woven fabric. The mixed yarn of the textile fiber and the binder fiber may be obtained by spinning by a conventional method, and the mixed yarn can be obtained by a fluid disturbance process such as interlace process.

The mixing ratio of the textile fiber and the binder fiber may be determined in consideration of the requirement for thread fraying depending on the application of the cloth tape, but since it affects the feel of the cloth tape,
It is also determined in consideration of the amount of the binder component.

The cloth tape of the present invention is obtained by cutting a woven fabric using at least the above-mentioned mixed yarn or mixed yarn as the weft yarn. It may be decided whether the mixed yarn or the mixed yarn is used for both the warp and weft or only the weft according to the demand for the yarn fraying and the feeling depending on the use of the cloth tape.
Even when used only for wefts, it is possible to prevent yarn fraying by fusing with the warp by the heat treatment in the subsequent process, and the textile fibers in the wefts are fused with each other by the binder component to bring the texture of the weft to the tape, resulting in a fine texture. It can work to keep the wide tape always open.

In the case where the binder fiber is not used in the warp yarn of the main part of the tape, but the yarn fraying is sufficiently prevented, the above-mentioned blended yarn or blended yarn is mixed with several warp yarns for each cut portion. It is preferable that the yarn is used and the mixed yarn or the portion where the mixed yarn is used comes to the ear after cutting.

The woven structure of the cloth tape of the present invention may be arbitrarily selected depending on the use of the cloth tape. The weaving width may be set according to the width of the loom.

In the fabric tape of the present invention, the woven fabric woven as described above is heat-treated at a temperature higher than the melting point of the binder component to fuse the warp yarn and the weft yarn with the binder component and to mix the spun yarn or the mixed fiber yarn. Fuse the textile fibers together.

Further, the heat-treated woven fabric is cut into a predetermined size to obtain the fabric tape of the present invention. When a mixed yarn or a mixed yarn is used as the warp of a constant width, this portion is cut. The present invention has the above configuration.

[0017]

The cloth tape of the present invention is obtained by cutting a woven fabric obtained by weaving a mixed yarn of the woven fiber and the binder fiber or a mixed fiber at least as the weft, after heat-treating at a temperature higher than the melting point of the binder component. With this heat treatment, the intersections of the warp and weft yarns can be fused together to prevent the yarn from fraying after cutting, and at the same time the textile fibers can be fused together with the binder component in the blended yarn or blended yarn to obtain the desired texture. ， High precision cutting property can be obtained.

When ε-caprolactone copolymerized polyester is used as the binder component, ε-caprolactone copolymerized polyester has a clear crystalline melting point, so that even if it is left in an atmosphere at a temperature below the melting point, it will be softened and fused. By performing the heat treatment at a temperature equal to or higher than the melting point, it is possible to obtain effective fusion between warps and wefts and fusion between fibers.
Further, as the copolymerization ratio of ε-caprolactone is increased, the binder component having elasticity can be used, and a fabric tape having a softer texture can be obtained.
