Abstract

PURPOSE:To produce a ceiling material covered with a surface material and excellent in touch, flexibility and design by putting nonwoven fabric having a hot melt layer laminated to one side thereof on a thermoformable core material composed of an inorganic fiber and a thermoplastic fiber or resin in layers and subsequently thermally forming it into a prescribed shape. CONSTITUTION:To one of the outsides of nonwoven fabric made of one or more kinds of natural and synthetic fibers, e.g. a polyester fiber, a thermoplastic fiber or resin layer having a melting point lower than that of the above-mentioned polyester fiber, e.g. a high-density polyethylene resin layer is laminated to prepare hot melt nonwoven fabric having a hot melt layer. On the other hand, an inorganic fiber such as glass fiber is blended with a high- density polyethylene fiber and the blended material is allowed to pass through cards to form a web. A needle punch treatment is applied to the resultant web to form a mat-shaped material and a high-density polyethylene film is subsequently laminated to each side thereof. A hot press treatment is then applied thereto using a flat press to obtain a thermoformable core material. After heating the hot melt layer of the hot melt nonwoven fabric, it is put on the above mentioned core material in layers and the resultant material is subsequently formed into a prescribed ceiling material shape, thus producing the objective ceiling material covered with a surface material.

Thus, for example, Japanese Patent Laid-Open No. 58-8735.
As described in Japanese Patent No. 3, a moldable non-woven fabric is proposed in which a mat obtained by needling two kinds of fibers having different melting points is heated to melt only the low melting point fibers and the mat is compressed. In Japanese Patent No. 31153, there is proposed a molding material in which a fibrous material is bound by an adhesive composed of two or more kinds of thermoplastic resins having different glass transition temperatures and incompatible with each other. Japanese Patent No. 71154 proposes an automobile ceiling interior material in which a polyester nonwoven fabric impregnated with a modified polystyrene resin is heat-sealed on both sides of a modified polystyrene resin foam, but both are core materials for interior materials. However, it cannot be used as a skin material excellent in texture, flexibility and design.

Further, in Japanese Patent Laid-Open No. 4-241159,
A heat-adhesive non-woven fabric made of heat-adhesive fibers using an ethylene copolymer as one component of a bicomponent fiber has been proposed. However, since this heat-adhesive non-woven fabric does not adhere to the core material via the adhesive layer, the adhesiveness to the core material made of different materials is not sufficient, and in order to increase the adhesive strength, Similar to the above-mentioned conventional technique, an adhesive is applied to the surface of the core material and / or the back surface of the heat-adhesive non-woven fabric to be laminated and laminated, or a sheet-like heat-activated material is applied between the surface of the core material and the back surface of the heat-adhesive non-woven fabric. It is necessary to sandwich objects by thermocompression bonding and stick them together, and again, it is necessary to apply and dry the adhesive, and for bonding, it is necessary to provide a separate heating step for the core material and the thermoadhesive non-woven fabric, which is complicated. There is a problem.
