Abstract

PURPOSE: To obtain the captioned blanket excellent in aptitude for printing by a method wherein, after a compressive layer is vulcanized incompletely by the irradiation of an electron beam, it is wound up in a drum for vulcanization and vulcanized completely in the drum, whereby unevenness of minute spherical bodies is prevented.
CONSTITUTION: A rubberlike elastic body (NBR, etc) wherein numerous hollow minute spherical bodies of thermoplastic plastics such as vinyl compolymer of chloride and vinylidene chloride are mixed uniformly is stretched on a fiber-reinforced layer 5 and dried. After that, it is exposed to the irradiation of the electron beam and thereby semivulcanized. Next, the vulcanization is completed in the vulcanizing drum according to an ordinary method. By the irradiation of the electron beam, the amount of reduction of the compressive layer 3 during vulcanization is reduced and the uneveness of the thickness can hardly be observed.
