は実質的に繊維が溶融し、フィルム化するので、風合が
硬化しやすく、また起毛された繊維以外の繊維はこの熱
融着部により固定化されているので、伸縮性が乏しい。In addition, the fabrication process of a raised nonwoven fabric made by partially heat-sealing the web is simple, but the fibers in the heat-sealed portion essentially melt and form a film, resulting in a stiff texture. Moreover, since fibers other than the raised fibers are fixed by this heat-sealed part, they have poor elasticity.
さらには起毛を多くすると布の強度が弱まるとともに耐
摩耗性がわるくなり、また逆に起毛を少なくすると風合
が硬くなり、伸縮性が乏しくなるので、風合がソフトで
伸縮性に富み、かつ布の強度と耐摩耗性を同時に満足さ
せることはできない。Furthermore, if the amount of napping is increased, the strength of the fabric will be weakened and its abrasion resistance will be reduced, and conversely, if the amount of napping is reduced, the texture will be stiffer and less elastic. It is not possible to satisfy the strength and abrasion resistance of cloth at the same time.

Among the above-mentioned fibers, those having a melting point that do not melt at a temperature 5° C. or more higher than the melting point of the thermoplastic sheet material can be preferably used. As a method for forming a web layer using the fibers, a normal web forming method such as a carding method can be employed.

態をとるように熱融着されてもよい。Next, the thermoplastic sheet material and a web layer made of fibers having a higher melting point than the thermoplastic sheet material are laminated, but the web layer may be laminated on one surface of the thermoplastic sheet material; A thermoplastic sheet material may be used sandwiched between two web layers. The laminated thermoplastic sheet material and the web layer are integrated by partially heat-sealing them from the fibrous web layer side. Such heat fusion may be performed, for example, at a temperature of 120 to 240°C, <160 to 2
A linear pressure of 10=100 is applied from at least the web layer side using a heating means such as an embossing roll heated to about 00°C.
kg/c+n, the thermoplastic sheet material is melted at the heat welding part, the fibers of the web layer are embedded therein, and in that state it is cooled and
The heating temperature and heating time are usually adjusted to solidify. Here, when heating from the web layer side, even if the fibers of the web layer are softened or melted and deformed together with the thermoplastic sheet material at the heat-fused portion, the web layer and the thermoplastic sheet material may As long as the fabric is sufficiently fused and the texture is not hardened, the resulting raised composite nonwoven fabric will have a mechanical strength that is satisfactory for practical use. good.
また熱融着は熱可塑性シート材料側から加熱したばあい
、融点はウェブ層よりも熱可塑性シート材料の方が低い
ため、加熱手段に溶融した熱可塑性シートが付着するこ
とがあるので、ウェブ層側から加熱するのが好ましい。In addition, when heat fusion is performed from the thermoplastic sheet material side, the melting point of the thermoplastic sheet material is lower than that of the web layer, so the molten thermoplastic sheet may adhere to the heating means, so the web layer It is preferable to heat from the side.

、目的、用途に応じて適宜決定される。The proportion (area) occupied by the thermally fused portion at the interface between the web layer and the thermoplastic sheet is preferably 5 to 35%. If the proportion of such heat-sealed parts is less than 5%, the mechanical strength of the web layer and the thermoplastic sheet will decrease, as well as the abrasion resistance, and if the proportion is more than 35%, it will cause a raised appearance. The texture of the composite nonwoven fabric becomes hard. In addition, the shape of the heat-fused part may be, for example, dotted, linear, circular, triangular,
The shape may be any shape, such as a quadrilateral or other polygon, and is determined as appropriate depending on the purpose and use.

熱可塑性シート材料の伸度に応じた伸縮性を有する。[Effects of the Invention] The raised composite nonwoven fabric of the present invention has excellent abrasion resistance as well as excellent tensile strength and tear strength because the raised fibers are fixed to the thermoplastic sheet material at the heat-sealed part. In addition, the surface of the web layer is brushed, giving it an excellent feel.The fibers of the web layer are virtually unconnected, giving it excellent drapability and making it ideal for thermoplastic sheet materials. It has elasticity depending on the degree of elongation.

温性に富んだ衣料材料、衛生材料として、さらには剪毛
したものは表面風合に優れ、ベルベット調の外観を呈す
る衣料材料、内装材などとして好適に使用しうる。In addition, because the shape, size, and arrangement of the heat-sealed part can be easily selected, raised composite nonwoven fabrics with various patterns depending on the purpose and use can be used, and clothing with a sense of volume and heat retention can be created. It can be suitably used as a material, a sanitary material, and even as a clothing material, an interior material, etc., which has an excellent surface texture and has a velvet-like appearance.
また、とくに熱可塑性シート材料としてフィルムラ使用
したものは、溶融した樹脂の逆滲みの発生を阻むので、
接着芯地として好適に使用しうる。In addition, especially those using film la as thermoplastic sheet material prevent the occurrence of reverse bleeding of molten resin.
It can be suitably used as an adhesive interlining.
