本発明はポリエステル繊維製のクツシヨン材に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cushion material made of polyester fiber.

び底づき感がして嫌われるなどの欠点がある。 Most cushion materials currently used in the furniture and bed fields are urethane foams.
However, since urethane foam undergoes a large change over time due to moist heat aging, it must be manufactured with a hard texture, which has disadvantages such as a feeling of hard texture immediately after production and a feeling of bottoming out, which is disliked.
本発明はこれらの欠点を除き、耐久性があり、

The purpose is to provide a polyester fiber cushion material that exhibits excellent performance.

ない。 The photo in the attached drawing shows a 70% high melting point polyester staple with a fineness of 10d and a length of 51mm, a fineness of 6d and a length of 51mm.
1 is an enlarged photograph of a cushion material of the present invention made of 30% low melting point polyester staple of 51 mm. As seen in this photo, a large number of staples are irregularly intertwined in three dimensions, and most of the low-melting-point staples melt due to heat, forming knots, and the multiple staples are fixed together at the intertwined part. I understand that. Further, since the entangled high melting point staples are only fixed by the molten blobs of low melting point polyester at the entangled portions, the excellent elasticity of the high melting point staples is unlikely to be diminished.

の利点がある。 The cushion material of the present invention shows almost no change in cushion performance over time due to moist heat aging, and can be customized to suit your preference from soft cushions to hard cushions by changing the mixing ratio of high melting point polyester staples and low melting point polyester staples. It can be manufactured using Further, by partially changing the mixing ratio, there is an advantage that a cushion material having a soft surface and a hard interior can be manufactured.

ばよい。 Examples of high melting point polyester fibers include ordinary polyethylene terephthalate, polyhexamethylene terephthalate, polytetramethylene terephthalate, poly1,4-dimethylcyclohexane terephthalate, polyhyvalolactone, or composite fibers produced by copolymer esters or conjugate spinning of these. I can give an example. The cross-sectional shape of the high melting point polyester fiber may be circular, irregularly shaped or hollow. On the other hand, low melting point polyester fibers are made of fatty acid dicarboxylic acids such as adipic acid and sebacic acid, aromatic dicarboxylic acids such as phthalic acid, isophthalic acid, and naphthalene dicarboxylic acid, and/or alicyclic acids such as hexahydroterephthalic acid and hexahydroisophthalic acid. A compound containing a predetermined number of group dicarboxylic acids and aliphatic or alicyclic diols such as diethylene glycol, polyethylene glycol, propylene glycol, and paraxylylene glycol, and optionally added with oxyacids such as parahydroxybenzoic acid. It is a polymerized ester, for example, a polyester obtained by copolymerizing isophthalic acid and 1,6-hexanediol with terephthalic acid and ethylene glycol. The fiber length of high melting point and low melting point polyester fibers is
It is sufficient that the staple length is 30 to 100 mm, which is a normal staple length, and the fineness thereof is usually 1 to 20 deniers.

適である。 The mixing ratio of high-melting point polyester fibers and low-melting point polyester fibers is 90:10 to 50:50 by weight, and if the mixing ratio of both polyester fibers is changed appropriately within this range, the material can be made from a relatively soft cushion material to a slightly soft cushion material. Even hard cushion materials can be obtained. In this case, if the ratio of high melting point polyester fiber exceeds 90%, the cushioning properties tend to deteriorate because the heat fusion between the fibers of the manufactured pine is insufficient. If it is less than %, the fused component will be too large and the produced mat will be too hard and unsuitable as a cushion material.

る。 The mixed web is laminated to a predetermined thickness and then heated. During this lamination, the density of the web is 0.005
~0.15g/cm <3> , preferably 0.01~0.10g/cm <3> . When laminated at such a density, the produced mat has a rebound resilience value suitable for use as a cushion material. The heating temperature of the laminated web is then a temperature between the melting points of the high melting point polyester fibers and the melting points of the low melting point polyester fibers. At this time, preferably the melting point of the high melting point polyester fiber is 200℃
In addition, since the melting point of the low melting point polyester fiber is 50° C. or more lower than that of the high melting point polyester fiber used at the same time, the heating temperature is determined according to the melting points of both polyester fibers. The heating means is preferably a moist heat means such as hot water, steam, or high-pressure steam. For example, a web packed in layers in a mold is molded into a mat using high-pressure steam. In this case, a dry heat means such as hot air may be used as the heating means, and it is also possible to perform continuous mat forming between endless belts.

というクツシヨン材も適宜に製造可能である。 The cushion material of the present invention is stronger than urethane foam, so it has the advantage that even if it is used alone as a pinerest, it does not feel bottomed out and is comfortable to sleep on. In addition, it has excellent durability because there is little change over time due to moist heat aging, and there is no need to manufacture it with hard grains like urethane foam. As a result,
In the present invention, not only can soft cushion materials or hard cushion materials be manufactured according to preference, but also the surface can be improved by laminating and molding an appropriate number of webs with different mixing ratios of high melting point polyester fibers and low melting point polyester fibers. Cushion materials that are soft and hard inside can also be manufactured as appropriate.

After evacuating the inside of the can, matte molding was performed using high-pressure steam at 130°C for 10 minutes. As a result, the low melting point polyester fibers are melted and a mat is obtained in which the low melting point polyester fibers are fused to the intertwined portions of the high melting point polyester fibers. When this pine is sliced into 10cm thick pieces, it exhibits excellent cushioning properties as a cushioning material for furniture.
