〔産業上の利用分野〕
この発明は自動車の天井内面に装着する成形天井に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a molded ceiling that is attached to the inner surface of the ceiling of an automobile.
従来基材上に不織布が溶着されたものが成形天井用に使
用されでいる。その基材としては紙質段ボール、熱硬化
性樹脂含浸繊維フェルト等が使用され、不織布としては
バインダーで接着したものがそのママ、又はポリウレタ
ンフォームを積層して基材に溶着して使用されている。Conventionally, nonwoven fabrics welded onto a base material have been used for molded ceilings. The base material used is paper cardboard, thermosetting resin-impregnated fiber felt, etc., and the nonwoven fabric used is one bonded with a binder, or polyurethane foam is laminated and welded to the base material.
成形方法はこれら基材を加熱成形型で成形後、表皮材の
裏面に熱融着性大有するフィルム、粉末、或いは網状体
を付着したものを展張して再度押圧して基材に溶着して
成形物としている。The molding method is to mold these base materials with a heating mold, then spread a film, powder, or net material with high heat-adhesive properties on the back side of the skin material, and press it again to weld it to the base material. It is made into a molded product.
上記のごと〈従来の成形は基材の成形後、表皮材を溶着
するために再度押圧成形がなされている。この発明は成
形の生産性を向上させるために一段成形で不織布を溶着
して成形天井とすることを目的としたものである。As mentioned above, in conventional molding, after the base material is molded, pressure molding is performed again to weld the skin material. The purpose of this invention is to create a molded ceiling by welding a nonwoven fabric in one step in order to improve the productivity of molding.
従来一段成形がなぜなされないかという点についてその
原因は一段成形後の不織布の復元力の作用によって一反

もたらすものが成形後における基材と不織布の復元力の
差の大小によることを予測してこの発明は成形後の復元
力の小さい不織布を開発しそれを使用することで一段成
形が可能となった。The reason why single-stage molding has not been done in the past is that the once-fused nonwoven fabric peels off due to the restoring force of the nonwoven fabric after single-stage molding. Predicting that the peeling phenomenon is caused by the difference in the restoring force between the base material and the nonwoven fabric after molding, the present invention developed a nonwoven fabric with a small restoring force after molding, and by using it, one-step molding is possible. It has become possible.
この発明で使用する不織布表皮材はポリエステル繊維が

にするためにプリントしたもの等が使用できる。A material with a net-like material attached to it, or a material with these welding materials attached to the back side through urethane foam, which does not use adhesives like conventional non-woven fabrics, is spread on a base material and heated. When pressed together with a base material in a mold, a molded body is obtained that is welded together at the same time as molding, and the nonwoven fabric skin material does not peel off due to changes over time. 5 heat-fusible conjugate fibers
If more than 0 parts by weight is used, the appearance and feel of the product will become paper-like and the soft feel will be poor, which is undesirable. Also, if it is less than 5 parts by weight, the abrasion strength of the product will be insufficient and pilling will occur. This is not desirable. The non-woven fabric is made by carding cotton with a card machine to make a fleece, laminating this with a cross layer to make a web, and then needle punching it.Using the above fibers as constituent fibers of the needle method non-woven fabric.Other particularly preferred. The skin material is 2 above.
After blending the short fibers of the seeds, they were carded using a carding machine, laminated using a cross layer, and a polyurethane foam layer was laminated and adhered to the back of the skin using the chain stitch method to soften the texture of the sliced surface of the web. Or you can use printed materials to make the surface appearance more colorful.

れた状態のコンジュゲート繊維が使用される。The heat-fusible Funshugate fiber used is a conjugate fiber made of polyethylene terephthalate, polyethylene terephthalate/inphthalate copolymer, polypropylene and polyethylene, etc., in which at least a resin with a lower melting point is exposed on the outer surface. Ru.
前記インフタレートは５〜３０重量部含むものが好まし
い。It is preferable that the inphthalate is contained in an amount of 5 to 30 parts by weight.
この発明の一段成形においては成形時は表皮材の繊維が
接着剤で固定されていないために伸ばされやすく熱圧に
より構成繊維中の溶着性フンシュゲート繊維の低融点成
分樹脂が溶融して復元力の弱い状態で固定してしまうた
め不織布表皮材の剥離が発生しない。In the one-step molding of this invention, the fibers of the skin material are not fixed with adhesive during molding, so they are easily stretched and the low melting point component resin of the fusible Funshugate fibers in the constituent fibers melts due to heat pressure, which reduces the restoring force. Since it is fixed in a weak state, the nonwoven skin material does not peel off.

After carding and cross-laying, a 180"/- nonwoven fabric was adjusted using a stitching machine. Next, a 50μ nylon 12 film was thermocompressed on the back side. Next, the temperature of the heating mold for the molded ceiling was set to 180℃. The base material and skin material were stretched and pressed for 90 seconds while pressing at several points around the periphery with a force slightly weaker than the mold pressure.Then, the molded product was removed from the mold, and after 24 hours, it was heated at 80°C for 4 hours at -40°C. A 4-cycle atmospheric test at 1.5 hours at 1.5 degrees Celsius was conducted and changes in shape were observed. There was no lifting of the skin material due to peeling, and there was no deformation such as twisting or warping.
