DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fiber-stuffed object such as futons and the like, and more particularly to a fiber-stuffed object having excellent use comfort, deodorizing properties, and being washable in a home washing machine or the like. Things.

[0002]

2. Description of the Related Art In the past, many fiber-stuffed objects such as comforters, mattresses, skin comforters, kotatsu futons, and cushions were mainly composed of stuffed cotton or cotton having a high side absorbency. However, because it is made of cotton, the side yards generate a lot of dust when used, and when washed with water, the dimensions shrink, the texture becomes rough and stiff, wrinkles are formed, and the dyes fall off and fade. There were drawbacks such as doing. In order to solve these problems, those using hydrophobic polyester-based synthetic fibers for wadding and side cloth have been commercialized. The stuffed cotton and side cloth of this polyester synthetic fiber were lighter than cotton, had excellent bulkiness, and were excellent in heat retention. In addition, even if the stuffed cotton and the side cloth are washed with a household detergent using a household detergent, the change in dimensions, bulk and appearance during drying is extremely small, and the drying speed is fast. Had features. However, polyester-based synthetic fibers are inferior in hygroscopicity, so that they tend to be stuffy, especially when used on the side, and have a problem of giving an unpleasant sensation during use due to poor antistatic properties.

[0003] It has been desired to solve these problems and to develop a fiber-stuffed object that can be washed at least with a home washing machine.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a material in which the side lining is made of a polyester synthetic fiber, wherein at least the side lining is provided with a hygroscopic property and an antistatic property, thereby providing excellent use comfort. Another object of the present invention is to provide a fiber-stuffed body which has a deodorizing property and can be washed with water.

[0005]

The fiber-stuffed object of the present invention has the following structure to solve the above-mentioned problems.

[0006] That is, a fiber-stuffed body composed of at least a side fabric and a wadding, wherein the side fabric is made of a polyester fiber having hygroscopicity and antistatic properties, and the wadding contains deodorizing fibers. A fibrous stuffed material comprising at least a moisture absorption / desorption parameter ΔMR of the side material of 1.2% or more, and the side material and the wadding are bound to each other with a sewing thread. .

BEST MODE FOR CARRYING OUT THE INVENTION The fiber-stuffed object of the present invention has a side material mainly composed of polyester fibers. At least the side ground has hygroscopicity and antistatic properties, and is made of a polyester fiber having a moisture absorption / desorption parameter (hereinafter referred to as ΔMR) of 1.2% or more. Here, the moisture absorption / desorption parameter ΔR refers to a value obtained by subtracting the moisture absorption rate at 20 ° C. × 65% RHΜR1 from the moisture absorption rate at 30 ° C. × 90% RHΜR2, and ΔR (%) = ΜR2 −Μ
It is given by the formula of R1.

The moisture absorption / desorption parameter ΔR provides comfort by absorbing perspiration of the human body in the case of using a fiber-stuffed object at the side of the object and releasing it to the outside air through the wadding or the outer side. The larger the moisture absorption / desorption parameter ΔR, the higher the moisture absorption / desorption capacity and the better the use comfort.

Therefore, when the moisture absorption / desorption parameter ΔR of the polyester fiber is less than 1.2%, it is not possible to obtain a high moisture absorption / desorption parameter ΔR even for the side ground, and the fiber-filled material cannot be used. The comfort of use due to moisture absorption and moisture release cannot be obtained. The upper limit of the moisture absorption / desorption parameter ΔR of the polyester fiber is generally about 30%.

The compound is preferably a polyfunctional carboxylic acid such as trimellitic acid or pyromellitic acid, or a polyol such as glycerin, trimethylolpropane, or pentaeristol, and particularly preferably trimellitic acid. The inclusion of the crosslinking agent (C) not only enhances the hygroscopicity of the polymer, but also has the effect that a crosslinked structure is formed in the polymer, and the physical properties of the fiber hardly change over time.

The proportion of the crosslinking agent in the copolymerized polyester is preferably from 0 to 30 mol%, more preferably from 1 to 15 mol%, particularly preferably from 2 to 10 mol%, based on the acid components constituting the whole polymer. .

It is preferable to use a linear polyester such as polyethylene terephthalate, polybutylene terephthalate, or polyethylene 2,6-naphthalate as a main glycol component. Of these, polyethylene terephthalate (usually polyester) is most preferred.

Examples of the form of the polyester fiber having hygroscopicity and antistatic properties used in the present invention include a core-sheath type composite fiber comprising a core 1 and a sheath 2 as shown in FIG. A core-sheath type composite hollow fiber composed of a core part 1, a sheath part 2 and a hollow part 3, a sea-island type composite fiber composed of an island part 1a and a sea part 2a as shown in FIG. 3, and bonded parts 1b and 2b as shown in FIG.
Preferred is a laminated conjugate fiber composed of, or a blended fiber.

When one component of the composite fiber is a copolymer polyester Y, for example, in the case of a core-sheath type composite fiber (FIG. 1) and a core-sheath type composite hollow fiber (FIG. 2), It is also possible to arrange Y and arrange a fiber-forming polymer Z such as polyester usually in the sheath. Further, the composite ratio (% by weight) of the core part is core / sheath = 5.

More preferably, it is 5 to 35% by weight, and still more preferably 7 to 30% by weight. The lower limit of the mixing ratio may be determined in order to provide sufficient hygroscopicity, and the upper limit of the mixing ratio may be determined from the viewpoint of preventing a decrease in spinnability.

When one of the composite fibers is polyetheresteramide X, the core-in-sheath type composite fiber, the core-in-sheath type composite hollow fiber, the sea-island type composite fiber, the laminated type composite fiber or the blended fiber is used as the fiber-forming weight. It is preferable that the blending ratio of the polyetheresteramide X to the combined Z is 15 to 50% by weight based on the total amount of the polymer.

The composite fiber or blend fiber used in the present invention can be produced by various composite spinning methods.

The cross-sectional shape of these fibers may be circular, but it is also preferable to use various irregular cross-sections such as triangular, flat, and multi-lobed or hollow cross-sections thereof.

In the present invention, in the case where the side of the fiber-stuffed object of the polyester fiber having the above-mentioned structure is a woven fabric,
When used, the fineness of the single fiber is preferably 0.1 to 10 denier. If the denier is less than 0.1 denier, the single fiber may be cut off when used as a side ground to cause dust, or the cut single fiber may be entangled to generate a pill called a pilling. On the other hand, if the single fiber fineness exceeds 10 denier, the texture of the side stiffness may become hard and the feeling of use may be deteriorated. Further, the total fineness of the polyester fibers used for the side ground is preferably 30 to 300 denier. If it is less than 30 denier, the tear strength of the fiber-stuffed object as a side land tends to be low, and the use durability tends to decrease. Also,
If it exceeds 300 denier, the thickness of the side layer becomes too thick, and the feeling of use may be deteriorated. Further, the density of the warp and the weft constituting the side fabric is preferably 50 to 200 yarns / inch. If the number is less than 50 pieces / inch, the tear strength may be low and the use durability may be reduced, or the function of not passing the fiber-stuffed object or the surrounding dust may be reduced.
On the other hand, if it exceeds 200 yarns / inch, the texture of the side stiffness may become stiff and the feeling of use may deteriorate.

As a cloth constituting the side of the fiber-stuffed object, a woven fabric, a knitted fabric, a non-woven fabric or the like can be used.
The above-mentioned polyester fiber having hygroscopicity and antistatic properties can be made into a woven fabric that is 100% used as a constituent fiber of the side of the fiber-filled object. It is preferable from the viewpoint of dryness. However, from the viewpoint of comfort in use, yarns twisted with synthetic fibers such as polyester fibers are usually used as long as they have antistatic properties and have a moisture absorption / desorption parameter ΔMR of 1.2% or more. Usually, a cross-woven fabric with a synthetic fiber such as a polyester fiber can be used. In addition, it has antistatic properties, maintains the moisture absorption / desorption parameter ΔMR at 1.2% or more, and twists and interweaves natural fibers such as cotton within a range that does not impair form stability, wrinkle resistance or quick drying property. A woven fabric can also be used.

Next, in the present invention, as the wadding used for the fiber-stuffed object, the fineness is 0.5 to 30 denier,
Short fibers having a fiber length of 10 to 100 mm are preferably used. If the fiber for filling cotton is thinner than 0.5 denier, the bulk as an aggregate required for filling tends to be low, and the resilience to compression and the recovery of bulk tend to decrease. When the thickness is larger than 30 denier, the touch tends to be coarse and hard. On the other hand, if the fiber length is shorter than 10 mm, the entanglement between the fibers is deteriorated, and the cotton tends to be broken. On the other hand, if it is longer than 100 mm, there is a tendency that the opening property and the cotton-making property are deteriorated.

The crimp of the fiber for filling cotton may be appropriately determined according to the intended use. The crimp of the fiber for bulking, softness, resilience to compression, resilience or cotton production is improved. In order to prevent movement and entanglement of the stuffed cotton, it is preferable that the stuffed cotton is mechanically crimped. More preferably, the asymmetric cooling treatment is performed during the production of the stuffed cotton fibers, and the fibers are three-dimensionally crimped by giving a structural difference to each fiber cross section. The number of crimps is preferably 3 to 10 peaks / 25 mm, and the degree of crimp is preferably 5 to 30%.

The cross-sectional shape of the filling fiber may be circular or hollow, but it is also possible to use a modified cross-section such as a polygon, or a hollow cross-section of the modified cross-section.

Also, as the fiber for filling cotton, if necessary, in addition to pigments such as titanium oxide and carbon black, various antioxidants, anti-coloring agents, light-proofing agents, antistatic agents and the like are added. be able to.

Next, in the fiber-stuffed object of the present invention,
The deodorizing fiber is contained in the filling fiber.

Furthermore, deodorizing properties can be imparted to the side of the fiber-stuffed object.

The deodorizing fiber is disclosed, for example, in JP-A-3-12480.
As described in JP-A No. 9, a fiber in which a deodorant component is kneaded into a polymer may be used.
As described in Japanese Patent Publication No. 78, a method of applying a deodorant component by post-processing may be used. As a method of applying the deodorant component by post-processing, it can also be obtained by grafting a free acidic group by graft polymerization. The acidic group in this method means a carboxyl group or a sulfonic acid group, and the content of the acidic group is 3.2 to provide durable deodorizing performance.
It is preferably at least × 10 ⁻⁴ gram equivalent / gram fiber, more preferably at least 9.3 × 10 ⁻⁴ gram equivalent / gram fiber. The terminal of the acidic group introduced by the graft polymerization is -COOH or -SO ₃
Most preferably, it is in the state of H, but it may be partially substituted by an ionic organic substance such as an alkali metal or an alkaline earth metal, or a general metal or a quaternary ammonium salt. It is preferable to distribute a large amount of acidic groups to the surface of the fiber by such graft polymerization, because malodor such as ammonia, hydrogen sulfide, and mercaptans, which are said to be the source of malodor, can be efficiently absorbed.

In the fiber-stuffed object of the present invention comprising the above-mentioned side material and wadding, the wadding, the side material, and the sewing thread are
From the viewpoint of facilitating the recyclability after the use of the stuffing object, it is preferable to constitute the polyester fiber 100%,
Fibers other than polyester fibers, such as cotton and nylon, may be mixed as long as the moisture absorbing property and antistatic property of the present invention are not impaired. When fibers other than polyester fibers having hygroscopicity are mixed, the proportion of the fibers used is such that the change in size, bulk, texture and appearance is reduced, the drying speed is increased, and the generation of dust from the side ground is reduced. From the side ground weight is preferably 40% by weight or less.

Further, from the viewpoint of minimizing the change in the dimensions, bulk, texture and appearance, it is preferable that the shrinkage of the fiber-stuffed body after washing with water is 0 to 5%. If it exceeds 5%, wrinkles may occur on the surface of the stuffed object, and the texture tends to be rough and rigid. The shrinkage ratio is measured by a method described later, and the higher value in the length direction and the width direction is preferably 5% or less.

Further, in order to enhance the drainage property and the drying property in the dehydration after washing with water, the quick drying property described later is 60 to 100%.
Is preferably, and more preferably 65 to 100%. If it is less than 60%, the drying speed is low, and it takes time to use it after washing, which is inconvenient. At the same time, the state containing a large amount of water is long, and dimensional change of the fiber-stuffed article tends to easily occur.

In the fiber-stuffed object of the present invention, it is necessary to bind the side fabric and the wadding together and bind them with sewing threads. The binding means can be quilted with various quilting machines,
The binding may be performed using a Japanese binding sewing machine or the like. The interval between quilting and binding is preferably at least 3 to 40 cm, and
30 cm is more preferred. If it is less than 3 cm, the binding interval is too narrow, which may impair the feel of the fiber-stuffed object or cause the sewing thread to be suspended by washing with water. On the other hand, if it exceeds 40 cm, the cotton wool may move or become entangled due to the kneading action when using the fiber-stuffed object or the kneading action when washing with water.
Here, the range of the binding interval is, for example, in the case of the futon, the quilting 4 or the Japanese binding 5 from the end of the futon like the quilting 4 applied to the comforter shown in FIG. 5 or the Japanese binding 5 of the cushion shown in FIG. This indicates that the shortest distance is preferably 3 cm or more and the longest distance is preferably 40 cm or less among the distances A _{1 to} Ai and B _{1 to} Bi between the quilting 4 and the Japanese spelling 5. . The stitch pitch of the binding may be appropriately determined depending on the use and the purpose of the use.

The above-described fiber-stuffed object of the present invention can be effectively applied to uses such as back cushions, stuffed toys, sleeping bags, stuffed jumpers and coats, in addition to comforters, mattresses, skin comforters, kotatsu futons and cushions. Can be.
