る。Conventionally, as an automobile interior material, a laminated material of a polyvinyl chloride sheet with a texture and a polyurethane sponge, a fiber knitted fabric or a raised fabric thereof has been used.
Non-woven fabric base materials are being used more and more due to cost reduction and fiberization, and needle-punched non-woven fabrics are dyed, and needle-punched with dyed fibers and then binder. Although the interior material impregnated with is used, due to the trend toward higher quality, expensive raised woven fabrics are also required for non-woven fabrics, which is why artificial leather based on non-woven fabrics may be used. Although it has been carried out, there is still a problem that a product obtained by impregnating wet urethane with fine denier is expensive and inferior in light resistance.

ものである。Therefore, the present invention has conducted extensive studies to solve the above problems of the napped nonwoven fabric interior material, and as a result, a fine denier highly shrinkable composite fiber and a mixed fiber using a finer fine denier highly shrinkable fiber than that. By crimping the needle punched non-woven fabric, the surface is relatively smooth and does not generate irregularities, is dense, has a soft texture and is highly stretchable, and napskin, suede, and velor tones by brushing. The present invention has been completed by finding a napped automobile interior material that satisfies short abrasion resistance, light resistance, and moldability of hair.

供するものである。The present invention is a high-shrinkage polyester composite fiber of 1 to 3d expressing a three-dimensional crimp (hereinafter, simply referred to as a high-shrinkage composite fiber) 50 to 70%, and 0.5 to 1.5 shrunk at a shrinkage ratio of 20% or more.
5-20% (weight ratio) of resin binder is impregnated and adhered to a needle punched non-woven fabric composed of a mixed fiber of 30 to 50% of highly shrinkable polyester fiber of d (hereinafter simply referred to as high shrink fiber) to make the surface smooth. A napped automobile with excellent abrasion resistance such as peach skin, suede, velor tone, light resistance, and moldability by forming a piled napped hair on the surface of the fiber mat The interior material is provided at a low price.

ない。As the high shrinkage conjugate fiber used in the constitution of the present invention, a fiber having a fineness of 1 to 3 denier is used, and if it exceeds 3 denier, it can be satisfied as an appearance textured napped automobile interior material. There will be nothing. On the other hand, if it is less than 1 d, a problem arises in the spinnability of the fiber, and the product value is lowered due to winding at the time of opening and unevenness, and a satisfactory product cannot be obtained.
次に該高収縮複合繊維の配合量は50〜70％（重量比）が
