And a molding process. In order to store the spherical cotton, which is light, bulky, and has slipperiness, into the container, a weighing device that sucks and stores the cotton into the container and then weighs is used in the process of weighing the spherical cotton. Then, the spherical cotton supplied from the measuring device is guided to a floating spraying device equipped with a stirring claw and a spray gun for binder liquid in the casing, and the spherical cotton is floated while being stirred, so that the floating cotton is spray gun. The above-mentioned binder liquid is sprayed in a spray state.

することができる。The spherical cotton sprayed with the binder liquid on the surface is press-molded after measuring a predetermined amount necessary for molding the product. The molding die used in the molding press has a structure in which the inside of a die constituted by an upper die and a lower die is heated by steam. Especially, it is preferable to supply steam to the lower mold,
Steam passes between or within a large number of globular cottons from the lower mold fumaroles. In the process, the urethane prepolymer mainly present on the surface of the spherical cotton is cured by the presence of heat and water to bond the spherical cotton. Further, as a method of further increasing the tear strength and providing durability, since a spherical cotton binder is attached, it is possible to lay a mesh cloth or a thin urethane product under or over the mold during molding.

ラとなり易いし、経済的ではなくなる。The adhesion amount ratio of the urethane prepolymer to the spherical cotton is 5 to 15 parts by weight, preferably 7 to 13 parts by weight, based on 100 parts by weight of the spherical cotton. If the amount of urethane prepolymer is less than 5 parts by weight, the adhesive effect will be poor, and if it is more than 15 parts by weight, the flexibility of the cushion material of the product will be lost, and it will be difficult for steam to pass, resulting in uneven molding. , Not economical.

As shown in FIG. 4, steam is supplied to the lower die 13 of the forming die 12 so that the steam enters the inside of the forming die 12 through the communication hole 14 on the bottom surface. Further, since the upper die 15 also has the vent holes 16 through which the steam passes due to the punching metal, the inside of the forming die 12 is appropriately heated by the steam to accelerate the polymerization of the urethane prepolymer, and the spherical die 1 is pressed by pressing. A cushion material product 17 having a high elasticity is obtained by organically joining a large number of pieces. The steam pressure for accelerating the urethane reaction by applying heat and water was set to 24.5 N / cm 2 (2.5 Kgf / cm 2 ) and maintained for 2 minutes. Since the cushioning material product 17 is wet due to the use of steam, it may be dried using a dryer or the like. The obtained cushion material product may be cut into a suitable thickness and shape.
