次に、本発明の複合シートは、前記の織編物が他の素材に熱接着されてなる複合シートである。その際、他の素材としては、使用目的に応じて適宜選定することができ、例えば、特開平７−４６６８３号公報の図３に開示されたような、０．３ｍｍ厚程度のＰＶＣ（ポリ塩化ビニル）シートに、直径が２ｍｍの穿孔を多数設けた、開効率１０％以上（好ましくは２０〜３０％）のプラスチックシートが例示される。なお、熱接着させる方法は特に限定されず、両者を適宜加熱しながら加圧する通常の方法でよい。 Next, the composite sheet of the present invention is a composite sheet in which the woven or knitted fabric is thermally bonded to another material. In this case, other materials can be appropriately selected according to the purpose of use. For example, as disclosed in FIG. 3 of JP-A-7-46683, PVC (polychlorinated) having a thickness of about 0.3 mm. An example is a plastic sheet having an opening efficiency of 10% or more (preferably 20 to 30%) in which a large number of perforations having a diameter of 2 mm are provided in a (vinyl) sheet. In addition, the method to heat-bond is not specifically limited, The normal method of pressurizing while heating both may be sufficient.
次に、本発明の成形体において、前記の織編物または複合シートを所定形状に加圧成形されていることが好ましい。成形加工は特開平７−４６６８３号公報の図４〜図１４に開示されているような、雌型と雄型との間に前記の織編物または複合シートをはさみ、加熱しながら加圧する方法でよい。本発明の織編物には、前記のような熱接着性繊維が含まれているので、構造が強固であり他素材と接着させなくても使用が可能である。また、複合シートは予め織編物と他の素材とを熱接着させたものでもよいし、成形加工と同時に熱接着させてもよい。 Next, in the molded body of the present invention, it is preferable that the woven or knitted fabric or the composite sheet is pressure-molded into a predetermined shape. The molding process is a method in which the woven or knitted fabric or composite sheet is sandwiched between a female mold and a male mold and is pressurized while heating, as disclosed in FIGS. 4 to 14 of JP-A-7-46683. Good. Since the woven or knitted fabric of the present invention contains the heat-adhesive fibers as described above, it has a strong structure and can be used without being bonded to other materials. Further, the composite sheet may be obtained by thermally bonding a woven or knitted fabric and another material in advance, or may be thermally bonded simultaneously with the forming process.
また、本発明の成形体において、バックインジェクションモールデイング法により、前記の成形加工用織編物に溶融ポリマーがインジェクションされ、所定形状に成形されていることが好ましい。その際、溶融ポリマーとしては、ポリエステルやポリオレフィンなど、通常のインジェクション用熱可塑性ポリマーを適宜使用することができる。かかる方法によれば、接着性の不織布が不要であり、また、１枚布であることから位置合わせが容易となる。 In the molded body of the present invention, it is preferable that the molten polymer is injected into the woven or knitted fabric for molding by a back injection molding method and molded into a predetermined shape. At that time, as the molten polymer, a normal thermoplastic polymer for injection such as polyester or polyolefin can be appropriately used. According to such a method, an adhesive non-woven fabric is not required, and since it is a single cloth, alignment is easy.
かかる成形体は、スピーカーネット、防塵ネット、コンピューターまたは家電製品の放熱スリット用防塵フィルター、換気扇フィルター、および通気孔用フィルターなどの繊維製品として好適に使用することができる。 Such a molded article can be suitably used as a textile product such as a speaker net, a dustproof net, a dustproof filter for a heat dissipation slit, a ventilation fan filter, and a vent hole filter of a computer or home appliance.
