もの等をいう。The short fiber nonwoven sheet of the present invention includes a mixture of a main fiber and two or more types of heat-adhesive fibers, which is made into a sheet using a carding machine, etc., a sheet that is laminated using a cross wrapper, etc. It refers to a layered product that is further processed by needling.

These include synthetic fibers such as nylon, polyester, and acrylic, and inorganic fibers such as glass, which are commonly used as textile fibers.

接着性繊維は、熱溶融・接着成分のみからなる繊維の場

とするのが、実用上の強力保持のためには好ましい。The heat-adhesive fiber used in the present invention is a fiber that has a component that heat-melts and adheres to the main fibers described above, and the heat-melt and adhesive component includes polyester resins and polyamide resins that can be made into yarn by melt spinning. , polybutyral acrylic resin, polyethylene-vinyl acetate copolymer, ethylene-acrylic acid ester copolymer, and the like. The heat-adhesive fiber may be a fiber consisting only of a heat-melting/adhesive component, but it is preferable to use a composite fiber with a heat-melting/adhesive component as a sheath component for practical strength retention.
本発明には、溶け始める温度が相互に５℃以上異なる熱
溶融・接着成分をもつ熱接着性繊維を２種以上用いる。In the present invention, two or more kinds of heat-adhesive fibers having heat-melting/adhesive components whose melting temperatures differ by 5° C. or more are used.

溶け始める温度が５℃以上異なる熱接着性繊維を２〜５
種混用することが、汎用性１機能性の面から好ましいと
の知見を得ている。The reason for using two or more kinds of heat-adhesive fibers is 1. By heat-treating the short fiber nonwoven sheet of the present invention at different temperatures, it can be made into nonwoven fabrics with different hardnesses, or when it is in sheet form, it can be made at a temperature that makes it easy to handle. This is to make it possible to obtain a nonwoven fabric with a desired hardness by heat-treating the fabric, cutting or sewing it, and then heat-treating it at a higher temperature. The inventor is
2 to 5 heat-adhesive fibers whose melting temperatures differ by 5℃ or more
It has been found that mixed use of species is preferable from the viewpoint of versatility and functionality.
熱接着性繊維の熱溶融・接着成分の溶け始める温度の差
が５℃未満の場合は、熱処理するときに溶け始める温度
が高いほうの接着成分も軟化・溶融する状態となり、硬
さの安定した製品が得られなくなる。安定した品質を得
るためには、溶け始める温度の差が１０℃０℃以上異の
が望ましい。If the difference in the temperature at which the heat-melting/adhesive components of the heat-adhesive fibers begin to melt is less than 5°C, the adhesive component that begins to melt at a higher temperature during heat treatment will also soften and melt, resulting in a stable hardness. product becomes unavailable. In order to obtain stable quality, it is desirable that the temperature at which melting begins differs by 10°C or more.
本発明の短繊維不織シート布に用いる熱接着性繊維の合
計の混率は、シートを構成する繊維全体の重量比で５〜
６０％の範囲である。熱接着性繊維の合計の混率が５％
未満の場合は、熱処理により溶融・接着しても硬さの変
化の評価ができず。The total blending ratio of the heat-adhesive fibers used in the short fiber nonwoven sheet cloth of the present invention is 5 to 5% by weight of the entire fibers constituting the sheet.
It is in the range of 60%. The total blending rate of heat-adhesive fibers is 5%.
If it is less than 100%, it is not possible to evaluate the change in hardness even if it is melted and bonded by heat treatment.
個々の熱接着性繊維の混率が少なく、温度を変えて熱処

〜５０％の範囲であるのが、汎用性１機能性等の点で好
ましい。熱接着性繊維の個々の混率は、最終用途の要求
特性を考慮して適宜配分する。The mixing ratio of individual heat-adhesive fibers is small, and even if heat treatment is performed at different temperatures, the difference cannot be evaluated. If the total blending ratio of heat-adhesive fibers is 60% or more, it may become too hard and not suitable for practical use, or the nonwoven fabric may not be able to maintain its shape due to shrinkage stress when the heat-adhesive fibers are melted, or plastic plates may In some cases, it becomes something different, such as Total mix rate is 10
The range of 50% is preferable from the viewpoint of versatility, functionality, etc. The individual blending ratios of the thermoadhesive fibers are appropriately distributed in consideration of the required characteristics of the end use.

ことができる。As a method for manufacturing the short fiber nonwoven sheet of the present invention, a method generally employed for manufacturing a nonwoven fabric made of short fibers may be employed. That is, the short fiber nonwoven sheet of the present invention can be obtained by mixing the main fiber and two or more kinds of heat-adhesive fibers at a predetermined mixing ratio and forming a web using a carding machine.
また、梳綿機で形成したウェブを積層したもの。It is also made by laminating webs formed using a carding machine.
さらに、積層したウェブをニードリング加工したものも
本発明の短繊維不織シートである。Furthermore, a sheet obtained by needling a laminated web is also a short fiber nonwoven sheet of the present invention.

た、溶け始める温度の最も低い成分をもつ熱接着性繊維
に接着性成分としての作用をさせておき、Ｒ断したり。The heat treatment of the short fiber nonwoven sheet of the present invention is performed by providing a heat treatment section following the step in which the short fiber nonwoven sheet of the present invention is manufactured in order to prevent the constituent fibers from scattering and to make them easier to handle. Often done. At this time, by changing the heat treatment temperature, nonwoven fabrics with different hardness can be obtained. Alternatively, the heat-adhesive fiber, which has the component with the lowest melting temperature, is allowed to act as an adhesive component and R-cut.
縫製した後、より高い溶け始める温度の成分の接着作用
により、要求される硬さにすることができる。After sewing, the required hardness can be achieved by the adhesive action of the components with higher melting temperatures.
