本発明は、硬わた成形体に関し、特にブラジャーカップ
用成形硬ゎたの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a molded hard cotton product, and particularly to a method for producing a molded hard cotton product for brassiere cups.
（従来の技術）
近年、ブラジャーやプラスリップ、水着等に用いられる

乾爆しに（いといった欠点以外にウレタンの湿分老化に
よる耐久性不良等の問題があった。(Conventional technology) In recent years, seamless types have become mainstream for bra cups used in bras, pluslips, swimsuits, etc. because they can express a natural bust line, and those made of urethane foam as a material are used to improve texture. It has been used because it is soft and has excellent rebound resilience. This is because the urethane foam sheet is aged at a high temperature of around 200 degrees Celsius, so in addition to the problem of yellowing of the urethane itself, the heat setting properties of the urethane are poor, resulting in deformation after washing and dry explosion. In addition to these drawbacks, there were other problems such as poor durability due to moisture aging of the urethane.
このため素材変更の試みがさかんに研究され、その結果
上として合成繊維からなるンート状不織布を熱形成する
方法等が検討された。しかし、この方法では成形が困難
で、高温で成形しても一回の洗濯で変形し、へたってし
まう等の問題があり商品化ができなかった。For this reason, attempts to change the material have been actively researched, and as a result, a method of thermoforming a thread-like nonwoven fabric made of synthetic fibers has been investigated. However, this method was difficult to mold, and even when molded at high temperatures, it deformed and sagged after one wash, making it impossible to commercialize the product.

This product overcomes the drawbacks such as poor elasticity, and the poor moldability of synthetic fiber non-woven fabrics.It has excellent moldability for brassiere cups, etc. mainly made of synthetic fibers, and is easy to wash. It is an object of the present invention to provide a method for producing formed hard cotton that is excellent in durability, has a soft texture like a urethane material, and has excellent impact resilience.

Examples of the synthetic fibers in the present invention include polyester-based, polyolefin-based, vinyl chloride-based, and vinylidene chloride-based synthetic fibers. Short fibers mainly composed of synthetic fibers (hereinafter abbreviated as A fibers) are short fibers containing preferably 50% by weight or more of the above synthetic fibers, and other fibers may be natural fibers, recycled fibers, etc. There may be. In addition, the above short fiber length is 20 to 10
0 m-, and if it deviates from this range, it will be difficult to mold and retain the shape, leading to problems in production. The above-mentioned A fibers are mixed with short fibers (hereinafter referred to as B fibers) containing a component having a melting point 20° C. or more lower than that of the synthetic fibers in the A fibers at least on the surface.

在する低融点成分との融点差は２０℃以上必要である。It is sufficient that the B fiber has at least on its surface a component with a melting point 20°C or more lower than that of the synthetic fiber in the A fiber, and the low melting point component and the high melting point component are arranged in parallel, for example, in a core-sheath structure, and each component has a core-sheath structure. Examples of the combination include polyethylene/polypropylene, polypropylene/polyester, nylon 6/nylon 66, ethylene[2vinyl/polypropylene, polyester/polyester copolymer, etc.]. The melting point difference between the synthetic fibers in the A fibers and the low melting point component present at least on the surface of the B fibers must be 20°C or more.
融点差が２０″Ｃ未満であると成形体の厚みが増す毎に
熱処理時の加熱ムラが増加し、融点しない部分が生じる
ので本発明から除外する。融点差の上限は特に限定しな
いが２００°Ｃ以下が好ましい。If the melting point difference is less than 20"C, heating unevenness during heat treatment will increase as the thickness of the molded product increases, and some parts will not have a melting point, so they are excluded from the present invention. The upper limit of the melting point difference is not particularly limited, but is 200° C or less is preferable.

は不適当である。Next, the mixing ratio of A fibers and B fibers is an important requirement in order to obtain excellent repulsion Yayoi, which is one of the objectives of the present invention. That is, the weight percentage of A fiber and B fiber is 90 to 30:1.
Must be between 0 and 70. If the mixing ratio of B fiber is less than 10% in terms of important ratio, there will be fewer bonding points, and even after heat treatment, only a fluffy and soft shape-retaining body will be formed as a whole, and the molded body will lack impact resilience as a molded body such as a brassiere base material. . Also, B
When the mixing ratio of fibers exceeds 70% by weight, heat treatment results in a hard, film-like shape-retaining body that does not have soft impact resilience and is unsuitable for molded articles such as brassiere base materials.

Press forming here does not refer to sheet press, but uneven press.
For example, press molding is performed using male and female molds made of air permeable wire mesh material, and the fiber aggregate is sandwiched between the molds at a temperature higher than the softening point of the low melting point component of the B fiber. Heat treated and welded. The obtained molded hard cotton has a density of 0
