DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plain weave rug used for spring and summer rugs, bath mats, kitchen mats, toilet mats, entrance mats and the like.

[0002]

2. Description of the Related Art Conventionally, many kinds of rugs of this kind are woven by plain weaving by arranging a plurality of spun yarns made of natural fibers in view of good texture and moderate water absorption. Conventionally, plain weave rugs using such spun yarns of natural fibers have inconsistent physical properties of the yarn and poor weaving efficiency, and also require the yarn to be weakly strong and have a high fineness, There is a problem that the rug has no stiffness and is inferior in dimensional stability. Further, in order to impart pest repellency, a drug is mainly applied, and the drug effect lacks sustainability.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a plain woven rug having new physical properties and functions, while having excellent functions such as appearance and touch feeling of natural fibers. .

[0004]

According to the present invention, a spun yarn of a natural fiber is wound as a yarn 3 around a core yarn 2 spun from a synthetic resin composition mixed with a pest repellent substance. This is a rug that is plain-woven and woven using the composite twisted yarn 1 that has been subjected to thermal processing to maintain the twisted state as a warp and a weft.

[0005]

According to the present invention, the synthetic resin yarn as the core yarn 2 imparts appropriate rigidity and long-term pest repellency, and a spun yarn is wound around the yarn to provide natural fibers 100 in appearance and feel. %, And has a moderately unpleasant taste as a rug.

The synthetic resin used for the core yarn 2 is a thermoplastic synthetic resin in terms of stable quality in continuous production and economical mass production. For example, ethylene, propylene, 1-butene, 4-methyl- In addition to polyolefin-based synthetic resins consisting of homo- or mutual copolymers of α-olefins such as pentene or copolymers of these α-olefins and other comonomers, polyamide-based synthetic resins such as nylon, polyethylene terephthalate And synthetic resins such as polyester-based synthetic resins, polyvinyl chloride-based synthetic resins, polyvinylidene chloride-vinyl copolymer-based synthetic resins, and the like, and blends of two or more of these may be used.

The synthetic resin forming the core yarn 2 includes N, N'-diethylmethtolamide, 2-hydroxyethyloctyl sulfide,
2,2-dimethyl-3- (2-methyl-1-propenyl) -cyclopropane-1-carboxylate, 2,2
A core yarn is obtained by mixing a pest repellent substance such as dibromo-3-nitrilepropionamide and melt-spinning the resin composition. It is optional to add a predetermined amount of additives such as a plasticizer, a lubricant, an ultraviolet absorber, an antistatic agent, a flame retardant, a colorant, and a filler to the resin composition.

The shape of the core yarn 2 is not particularly limited, and monofilaments, multifilaments obtained by converging low-fineness monofilaments, flat yarns obtained by stretching a tape shape, and split yarn treatments on flat yarns. Specific examples include split yarns.

The spun yarn which is the wound yarn 3 wound around the core yarn 2 is, for example, a spun yarn made of natural fibers such as a wool spun yarn, a cotton spun yarn, a hemp spun yarn and a rayon spun yarn. In addition, a composite twisted yarn 1 is obtained by applying a tension to the core yarn with a general ring-type twisting machine and subjecting the core yarn to twisting. The composite twisted yarn 1 is heat-set at a temperature equal to or lower than the melting point of the core yarn resin in order to maintain the twisted state.

The composite twisted yarn 1 is used as a warp and a weft, and is plain-woven by a conventional loom such as a rapier loom, a shuttle loom, a tuft loom, and a hook sewing machine to form a rug.

[0011]

[Embodiment] Hereinafter, an embodiment will be described.

Example 1 A split yarn having a fineness of 1,150 dr obtained by melt-spinning a resin composition obtained by adding 5 parts by weight of 2-hydroxyethyloctyl sulfide as a pest repellent substance to 100 parts by weight of a polypropylene resin. The core yarn 2 is used as the core yarn 2 and the four cotton spun yarns are used as the winding yarn 3 to obtain 8
After twisting the yarns per inch, the yarn was passed through a 125 ° C. oven and heat-set to obtain a composite twisted yarn 1 having a total fineness of 3,000 dr.

Using this composite twisted yarn 1 as a warp and a weft,
The rug was obtained by plain weaving with a rapier weaving machine at a driving density of 8.5 × 20 / inch.

This embodiment has a moderate stiffness, excellent dimensional stability, and a small variation in strength, as compared with the conventional cotton spun yarn rug. The weaving efficiency was also good due to the stable physical properties. In addition, the effect of pest repellency was confirmed to maintain a high level of pest repellency of 80% or more for 12 months or more, and the duration was more than twice that of conventional products.

[0015]

As described above, according to the present invention, while the spun natural fiber yarn exposed on the surface maintains good touch and good water absorption, the strength and rigidity of the core yarn made of synthetic resin are increased. The rug can contribute to imparting the physical properties of the pulp, and can maintain the pest repellency, which is a medicinal effect, for a long period of time due to the drug mixed into the core yarn.
