DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chenille yarn using wool fiber and a sheet material made of the yarn.

[0002]

2. Description of the Related Art Chenille yarn has conventionally been used as a decorative yarn in the form of a moor yarn. However, the form of the chenille yarn is such that the flower yarn held by the core yarn is formed in a pile around the core yarn. Surrounding the yarn is a yarn having a cylindrical shape as a whole. Conventionally, such a chenille yarn can be produced by a method in which a woven fabric is finely cut in the warp direction and twisted into a mortar-like yarn, or a special device for producing chenille yarn.

[0003] As one method for producing such chenille yarn, Japanese Patent Application Laid-Open No. 2-14035 discloses a method in which a core yarn of chenille yarn containing 50% or more of a heat-adhesive conjugate fiber is used. Chenille yarns using cotton, hemp, silk, wool and the like are described. Combinations of such yarns are known, but not all of these yarns have been put to practical use. In particular, chenille yarns using wool fibers as the yarns are expected to be used for applications that take advantage of the characteristics of wool fibers, but due to the drawback of falling off the yarns, wool fibers are actually used for the yarns. The chenille yarn has not been put to practical use.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a chenille yarn in which wool fiber is used as a yarn by improving the above-mentioned problems. The yarn does not fall off and is suitable for special applications. To propose a new chenille yarn.

[0005]

According to the present invention, there is provided a chenille yarn formed by twisting core yarns and holding the yarn fibers, wherein at least one of the core yarns contains a melt-adhesive fiber, The fiber is a chenille yarn characterized by using a wool fiber that has been subjected to surface scale removal treatment, and is a sheet material made of a woven or knitted fabric created using the chenille yarn.

[0006] The core yarn used in the present invention is not particularly limited, and either a filament yarn or a spun yarn can be used. Usually, a core yarn other than the melt-adhesive fiber and a core yarn composed of the melt-adhesive fiber are used. Are preferably used as a mixture, and a spun yarn is preferably used as the core yarn other than the melt-adhesive fibers. As the spun yarn, in addition to those made of natural fibers, those made of synthetic fibers and those obtained by mixing the natural fibers and the synthetic fibers can be used.

In the present invention, it is important that at least one of the core yarns contains a melt-adhesive fiber. The melt-adhesive fibers include a dry heat temperature of 80 to 130.
A material having a performance of melting and bonding by heat treatment at a temperature of ° C. is used, for example, polyamide having a low melting point (nylon 6, nylon 66, nylon 610, or a copolymer thereof).
Alternatively, fibers made of high-density polyethylene and low-melting polyester can be used.

In addition, these melt-adhesive fibers have the sheath made of the low melting point thermoplastic polymer and the core made of the thermoplastic polymer having a melting point higher than the low melting point polymer by 20 ° C. or more. A core-in-sheath type conjugate fiber as used in the above may be used. In the present invention, since wool fibers are used for the yarn, it is preferable to use the melt-adhesive fibers having a dry heat temperature within the above range (wet heat temperature: 80 to 120 ° C.).

On the other hand, wool fibers are used as the fiber yarns. As the type of wool fibers, merino species are preferably used, and those having a quality of 66's or more are particularly preferably used. It is important to use those wool fibers that have been subjected to a treatment for removing scale present on the surface thereof. The wool fiber has an outer skin (cuticle) portion on its surface and is usually called a scale. Of the outer skin portion, it is necessary that the outermost layer of the epicuticle portion is removed. To confirm that the epicuticle portion has been removed, it is necessary to express the scale removal rate as 6 to 12
% Is preferably used.

[0010] The scale removal rate can be obtained from the weight A of the wool before the scale removal treatment and the weight B of the wool after the scale removal treatment as (AB) x 100 / A. However, the converted weight corrected using 18.25% as the water content is used as the weight of the wool.

[0011] The scale removal treatment of such wool is not particularly limited, but a treatment using a treatment device (cloi processing treatment device) developed by Canada Croy is preferably exemplified. In this method, chlorine is used as a chlorinating agent. Using gas,
Hypochlorous acid is generated by mixing chlorine gas and water with an injector and reacted with wool in an acidic atmosphere. The chlorine solution is supplied to the wool by a spray method, and the treatment is performed using a treatment area comprising a U-shaped tubular reactor. The chlorine solution supplied to the wool can be uniformly treated by a combined effect of capillary action and hydrostatic pressure. In this method, the degree of scale removal is adjusted by adjusting the time of passing through the treatment zone (the action time of the fiber and chlorine).

The degree of descaling can be checked by a wool fiber wettability test. In the present invention, those having a wettability in a range of 100 to 220% measured by a gravimetric method are preferably used, and particularly preferably 130 to 20%.
A range of 0% is used. The following method is used for evaluating the wettability. In other words, this method utilizes the capillary action of wool fiber, and a plastic pipe having a diameter of 7 mm and a length of 100 mm is put into a plastic pipe of about 10 g / m.
Of a wool sliver, and a plastic pipe containing the wool sliver is set on a petri dish containing red ink, left for 20 minutes, and the amount of ink sucked up is measured. As the red ink, 1 cc of commercially available red ink filled with 20 cc of water is used.

[0013]

(Equation 1)

The chenille yarn of the present invention supplies such a yarn (wool fiber) to a special chenille twisting machine, and while the yarn is twisted into a plurality of core yarns, the yarn is appropriately lengthened by a cutter. And finally heat-treated so that the core yarn is melt-bonded and gripped so that the yarn does not fall off. More specifically, for example, using a device as disclosed in Japanese Patent Application Laid-Open No. 49-101650 or the like, winding a yarn on one vertex of a triangular plate (a yarn feeding plate), A plurality of core yarns containing the above-mentioned melt-adhesive fibers are supplied to the yarn winding portion, and a cutter is acted from below the yarn feeding plate to cut and branch the yarn portion into two branches. The chenille yarn can be obtained by lowering the respective yarns along the shape of the triangular plate, guiding the yarns together with the core yarn supplied as described above to the ring twisted yarn portion and twisting them.
The range of the number of twists to be twisted is 400 to 2,000 T / m, but when the count of the chenille yarn is 1 / 4.0 count (meter count) or less, the twist number of 600 to 800 T / m is used. When the count of the chenille yarn exceeds 1 / 4.0 count, a twist number in the range of 800 to 1,000 T / m is preferably used. If the number of twists is less than 400 T / m, the chenille yarn finally obtained is not easily formed into a cylindrical shape, and a beautiful yarn cannot be obtained. On the other hand, if the number of twists exceeds 2,000 T / m, the convergence of the yarn is large, and the characteristics of the fibers used for the yarn and the bulkiness of the chenille yarn are undesirably impaired.

FIG. 1 is a side view schematically showing a chenille yarn of the present invention, wherein 1 is a core yarn and 2 is a flower yarn. The flower yarn 2 is substantially arranged in a cylindrical shape around the yarn axis by twist given to the core yarn. The range of the count of the chenille yarn produced by the present invention is 1/1 to 1
/ 10th (metric number) is mainly created.

The yarn used for the chenille yarn has a length from one cut end to the other cut end of 3%.
Those having a size in the range of up to 30 mm are preferably used.

[0017]

The chenille yarn of the present invention thus obtained has a feeling and high-grade feeling that cannot be obtained with the conventional chenille yarn. That is, wool fibers could not be used as the yarn in the conventional chenille yarn. It cannot prevent the wool fiber from falling off even if twisted and gripped with a core yarn, and even if a conventionally known melt-adhesive fiber is used for a part of the core yarn. However, the adhesiveness to wool fiber was poor, and the yarn could not be gripped sufficiently. In any case, chenille yarn using wool fiber as the yarn had not been put to practical use. In the present invention, the use of a wool fiber that has been subjected to a descaling treatment solves such a conventional problem. The scale-removed wool fiber is gripped by the melt-adhesive fiber so that the yarn does not fall off. A chenille yarn is obtained.

The chenille yarn thus obtained is
It can be used for producing fabrics used for clothing and industrial materials. In the case of a woven or knitted fabric which is a fabric using chenille yarn, the operation of raising or raising the hair conventionally performed in order to obtain a raised surface is unnecessary, and a fabric having a raised surface can be easily obtained. That is, conventionally, in order to obtain a woven or knitted fabric in which a pile is formed on a fabric surface using wool fibers, the surface of the woven or knitted fabric is raised to a raised surface, or a pile woven or knitted fabric is woven and a fabric structure is used. Those that form a raised surface are known. In the case of using the raising method, the wool fibers which are raised during the raising are damaged, so that the elastic properties are impaired. In addition, the raised surface of the plain fabric is subjected to the raised processing, so that the raised property of the raised hair is problematic. There is
There are problems of insufficient density of nap fibers, insufficient bulkiness as a sheet material, and poor elastic properties. In addition, on the nap surface where a pile is formed using a fabric structure, the nap density cannot be increased due to organizational restrictions, and the bulk and elastic properties of the sheet material are insufficient.

On the other hand, in the sheet material using the chenille yarn of the present invention, since it is arranged in a direction perpendicular to the yarn axis direction by the twisting of the yarn, it cannot be obtained by the conventional woolen knitted fabric. A sheet material having properties and feeling can be obtained.

As described above, the woven or knitted fabric using the chenille yarn of the present invention has a higher surface repulsion and a special feeling than the woven or knitted fabric in which a pile is formed using a conventional wool spun yarn. . Since the wool fiber is used for clothing, the texture is good, the fabric is tight and waisted, and the scale is removed, so that the thread does not fall off. Further, it has an advantage that it is glossy as compared with ordinary wool and does not tingle on the skin, and can be used as a material for outer clothing such as a jacket, a blazer, a skirt and the like for clothing.

The chenille yarn of the present invention can be used as a woven or knitted fabric or the like and used as a sheet material for a vehicle seat or a general chair upholstery.

Hereinafter, the present invention will be described with reference to examples.
