。[Prior Art] Conventionally, various materials have been used for cushions for vehicle seats and the like. For example, palm rock made from coconut fibers, synthetic resin foams such as urethane foam, and cotton, an organic synthetic fiber, have been used. However, palm rock has a high specific gravity and easily sag, which poses problems in the stability of raw material supply, while urethane foam has poor breathability and tends to get stuffy, making it uncomfortable to sit on. Furthermore, cotton, which is an organic synthetic fiber, has the drawbacks of low hardness and large settiness.

る。Therefore, in recent years, a cushion body formed by bonding intersections of three-dimensionally intertwined organic synthetic fibers with a urethane resin has been developed and proposed in Japanese Patent Application Laid-Open No. 158437/1983. This cushion body has the advantages of excellent breathability, resistance to fatigue, high durability, and light weight.

の粘度を調整して用いていた。[Problems to be Solved by the Invention] When producing a cushion body made by bonding intersections of three-dimensionally intertwined organic synthetic fibers with a urethane resin, the organic synthetic fibers are usually impregnated with a urethane prepolymer, and then urethane is added to the cushion body. The prepolymer was being cured. In this case, since the urethane prepolymer has an extremely high viscosity and cannot be impregnated into organic synthetic fibers, the urethane prepolymer is diluted with an organic solvent to adjust the viscosity of the urethane prepolymer.

ある。However, 1,1,1-trichloroethane and the like used as organic solvents are highly toxic and cannot be disposed of as they are due to environmental concerns, and large-scale recovery equipment is required. Furthermore, since steam is used to cure the urethane prepolymer, expensive equipment such as a boiler is required.

A method for manufacturing a cushion body is provided, which includes the step of heating and curing a prepolymer emulsion.

ソシアネート化合物を反応させて得たものである。The blocked aqueous urethane prepolymer used in the present invention is produced by reacting a polyol obtained by addition polymerizing a mixture of ethylene oxide and propylene oxide with glycerin, etc., with an isocyanate compound whose isocyanate groups are blocked with a blocking agent such as phenol. This is what I got.
プレポリマーのエマルジョンの濃度は、２５〜３５が好
ましい。The concentration of the prepolymer emulsion is preferably 25 to 35.

量比が８＝２〜６：４となるように行うのが好ましい。In the present invention, it is preferable to remove excess emulsion using a centrifuge, a mangle, etc. so that the weight ratio of the fibers and the emulsion is 8=2 to 6:4.
硬化のための加熱温度は、ブロック剤の解離温度以上で
あり、１１５〜１５０℃が好ましい。The heating temperature for curing is higher than the dissociation temperature of the blocking agent, and is preferably 115 to 150°C.

剤を用いることなく水により自由に濃度の調整が可能で
あり、所望の濃度のエマルジョンを容易に立体的に絡み
合った繊維に含浸させることが出来る。Since this urethane prepolymer is hydrophilic, its concentration can be freely adjusted with water without using an organic solvent, and the three-dimensionally entangled fibers can be easily impregnated with an emulsion of a desired concentration.

る。In addition, since the isocyanate groups of the urethane prepolymer are blocked with a blocking agent, it is possible to perform impregnation and deliquification while maintaining crosslinking properties. It can be easily hardened by heating to a temperature higher than the dissociation temperature of the blocking agent.
