PURPOSE:To obtain the title material suitable for mass production, by accumulating a great number of staple fibers made of synthetic resin, subjecting to hot melting treatment to give a hot melted fiber aggregate and further bonding the contact points of mutual staple fibers of the aggregate with an adhesive. CONSTITUTION:A great number of properly curled staple fibers made of synthetic resin are multiplied, molded into a given shape, subjected to hot melt treatment at 130-160 deg.C, bonded at mutual contact points of the staple fibers in such a degree as not to release the staple fibers separately in the following process and molded into a given shape to form a hot melted fiber aggregate. Then the hot melted fiber aggregate or the hot melted fiber aggregate cut into a given shape is surely bonded at mutual contact points of the staple fibers to give the objective cushioning material useful for beds, seats of automobiles, etc. |
