PURPOSE:To obtain a solid fiber aggregate having high compressive strength and high compression residual strain ratio, and contribute to the solution to problems of environment and resources by using recycled thermoplastic resin containing polyester resin of specific ratio as a resin compound. CONSTITUTION:In a resin compound for a solid fiber aggregate having a void formed spot-welded with linear threads each other, the resin compound is used from recycled thermoplastic resin containing 70wt.% polyester resin. As a result, a solid fiber aggregate hard to fatigue and having high compression strength and also high compression residual strain ratio is obtained, and the solid fiber collector is used for favorably civil engineering drainage materials such as culvert, fill, retaining wall, backing, etc., or cushion members such as bed, etc. According to the constitution, resin of molded goods disposed after using them or defectives, etc., can be effectively reused. |
