Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ribbon tape made of synthetic fibers.

<Conventional technology> Conventionally, in the production of ribbon tapes made of polyester filament yarn, in order to prevent the occurrence of wrinkles, edge curls, or width discrepancies during dyeing, the tape is stretched with greige fabric, heat set, and then There is a need to dye the ribbon tape, so the bulge and texture of the ribbon tape are almost ignored.

<Problems to be Solved by the Invention> The present invention provides a velvet-like texture that has an excellent overall sense of fullness, has a pattern with a three-dimensional effect, has a shadowy luster and color tone, and is free from cracks in the ground. We aim to provide a ribbon tape based on the following.

<Means for Solving the Problems> The present invention provides a structure in which the warp has a long float, such as a satin twill weave, which consists of a warp composed of Lunpei filaments with an oblateness of 2.5 to 15 and a weft of a false twisted yarn. A ribbon tape woven with warp yarns at least on the surface, where the oblique planes of 30% or more of the warp fibers stand up at an angle of 45° or more with respect to the tape surface. and the oblique plane of most of the warp constituent fibers is 3° with respect to the tape surface.
Rippon tape is characterized by having a sideways roughened portion of 0° or less, and two tapes with different shrinkage characteristics as warp threads.
More than one type of polymer is laminated in the width direction, and the flatness is 2.
5 to 15 and a torsion shrinkage rate of 3 to 40%, a coarse yarn composed of composite flat filaments is used, and a false twisted yarn of low shrinkage synthetic fiber is used as the weft to prevent floating of the warp. This method of manufacturing the ribbon tape is characterized in that the ribbon tape is woven with a long structure, subjected to hot water treatment such as scouring and dyeing under no tension to shrink in the warp direction, and then hot-pressed on the surface in a pattern.

FIG. 1 is an example diagram showing a cross section of the adhesive tape of the present invention.
A part 4 consisting of a warp 2 composed of flat filaments 1 and a weft 3 of a false twisted yarn, where at least a part of the flat plane of the warp constituent fibers stands up with respect to the tape surface at a floating part 2 of the warp. This shows a structure in which most of the warp constituent fibers have a portion 5 lying sideways.

First, the flatness L of the filaments constituting the warp of the present invention
/W is required to be 2.5 to 15.

Here, L%W refers to the maximum flame and maximum width of the fiber cross section shown in FIG. l, /W or 2.5
If it is smaller, even if the flat surface of the tape stands up, it will not give sufficient bulge to the tape, and it will be difficult to obtain a shaded gloss or color tone. Hard to get. Moreover, even if 1./W exceeds 15, it is difficult to raise the oblique plane, and the above-mentioned object of the present invention cannot be achieved. The flat fibers may have protrusions in the longitudinal direction on the flat surface.

In order to raise the oblique plane of the warp fibers, it is necessary to create a satin structure in which the warp threads float for a certain length, and the warp fibers must be twisted at the floating portion of the warp, preferably by increasing the distance of the floating portion of the warp. The relationship between LU and twist pitch P is LU≧
-1-P The selection is preferably made so that LC≧TP. The twist of the flat fiber is given by the twist of the warp threads or the twist of the flat fiber itself. Flat twisted fibers are used which have not been crimped using the knitting or knife method.These flat fibers are prepared as latent twisted fibers, and the twist becomes apparent through processes such as heat treatment after weaving.
Sign.

In the present invention, in the portion 4 where the warp constituent fibers rise, it is necessary that 30% or more, preferably 50% or more of the warp constituent flat fibers rise or rise at an angle of 45° or more with respect to the tape surface. . If the rising angle of the fibers is less than 30%, the tape will not swell (thickness) in this area, and it will be difficult to obtain a unique velvet-like gloss and color tone with shadows.Also, if the rising angle is less than 45°, , even if the number is large, the desired effect of the present invention cannot be obtained.

On the other hand, in the part 5 where the warp constituent fibers are laid down, most of the warp flat fibers, preferably 60% or more, are 3% or more with respect to the tape surface.
It is necessary to have a sideways angle of 0° or less, and by rolling, the raised part of the flat fibers, gloss, and color tone difference are made clear, and a clear pattern is created.

In addition, in the ribbon tape of the present invention, it is important to avoid using heat-processed yarn as the weft yarn, in order to increase the bulge of the tape and to prevent the tape from forming. In particular, processed yarns made of multi-filament yarns (high count yarns) with a single fiber denier or a denier of 1.2 d or less are effective. In addition, wrinkles and cracks in the processing process such as dyeing,
In order to prevent the occurrence of ear curls, the hot water shrinkage rate must be 8.
False-twisted yarns made of 0% or less low shrinkage fibers are desirable.

When manufacturing the above-mentioned ribbon tape of the present invention, two or more types of polymers having different shrinkage characteristics are laminated together in the width direction as warp threads, the flatness is 2.5 to 15, and the torsion shrinkage rate is 3. It is particularly desirable to use a yarn composed of composite flat filaments of ~40% and to use a false twisted yarn of low shrinkage synthetic fiber as the weft yarn.

The composite flat filament is a composite in which components a and B, which have shrinkage rates different by 2% or more, are laminated to each other in the width direction of the flat filament. A% B component is polyester, polyamide, polyolefin, polyether ester, polyacrylonide l) tL-1;'r: ! Any material that can be used to form fibers such as vinyl alcohol, cellulose polymers, or other materials may be used, and may also be a mixture or composite of these materials, or a material containing approximately 20% by weight or less of an additive. More preferred are polyester and polyamide, and particularly preferred are two-component composite flat fibers of polyesters having different shrinkage properties.

Next, examples of preferred combinations of two-component polymers as the composite two-component of the present invention will be shown, but the fibers of the present invention are not limited thereby. In the present invention, ii) and V) are particularly preferred among the following.

The fibers used in the present invention are discharged from a nozzle as a composite stream of two components A and B and taken up (500 to 6,000
m/min), fibers are easily formed. The unstretched system that has been collected is stretched 1.1 to 50 times using the usual method.
Sign.

In general, the preferred conjugate fibers used in the present invention have the following torsional shrinkage ratio (Nor) of 3 to 40%. In other words, the torsional shrinkage rate Nov is
A load of g/d was suspended and treated in 90°C hot water for 30 minutes,
Dry with a load applied, measure the length el of the comb, and then measure the length 12 when a load of 5 on 9/d is hung.
Find f'L from the following.

Here, if Nor is less than 3%, torsion of 11° will occur in the fabric, so that only the flat plane can be obtained that is almost parallel to the fabric surface, and if Nor is more than 40%, twist will occur in the fabric. The curls become close to crimp, and the effects of the present invention are not fully exerted.

In addition, as low-shrinkage synthetic fibers, for example, polyester fibers that have been sufficiently heat-relaxed after stretching to reduce the shrinkage rate in hot water are used. preferable. If a false twisted yarn made of fibers with a hot water shrinkage rate of more than 8% is used, it is undesirable because it tends to cause uneven width of the ribbon tape during dyeing, and also causes cracks in the warp threads or disordered fibers. The preferable hot water shrinkage rate of the weft fibers is 8% or less, generally 5% or less.

In the present invention, after forming a ribbon tape using such warp and weft yarns with a structure in which the warp yarns are long floating, such as satin fibers, the ribbon tape is contracted in the warp direction by treatment with hot water or the like under high tension. . As this treatment, normally employed steps such as scouring and dyeing are employed, but the tape may be shrunk in the warp direction in advance and subjected to dyeing or the like.

In this method, when the woven ribbon tape is treated with hot water, the twist of the composite flat fibers constituting the warp is preserved, and in the floating part of the warp, the flat surface of the flat fiber is against the tape surface. stand up. In addition, when using flat fibers made of a single polymer as warp threads, it is effective to use fibers with a high hot water shrinkage rate, preferably 15% or more.

Next, in the present invention, the ribbon tape that has been subjected to the above-mentioned treatment is heated, for example, with a heating pattern imprint roll, to form a portion in which the flat fibers are laid down. As a result, three-dimensional patterns, letters, etc. are made to appear on the surface by the portions where the flat fibers stand up and the portions where they fall sideways.

In addition, in the present invention, it is not necessary that all of the warp yarns are flat fibers, and they may be interwoven with other yarns.

Functions and Effects> Since the ribbon tape of the present invention has a special structure as described above for the warp threads, the tape itself has a bulging feeling,
Moreover, it has a unique luster and color tone with shadows without causing any division, and the parts where the flat fibers stand up (convex parts) have a velvety-like appearance, and the parts where the flat fibers lie sideways (concave parts) have a velvety appearance. ) has an extremely smooth and glossy appearance, and the combination of the two creates a patterned ribbon tape with a luxurious feel.

In addition, according to the method of the present invention, shrinkage in the warp direction is allowed during dyeing, etc., but shrinkage of the weft yarns is reduced, thereby eliminating tape wrinkles, edge curls, and ground cracks, and preventing uneven width. The only thing that can be done is to easily manufacture a unique tape like the one mentioned above.
