Coating thermally sensitive textile webs with plastics pattern - by passing preheated web in contact with cooled drum provided with spots of material

摘要

Textile web is coated with pulverulent plastics material by passing the web in contact with a water cooled drum provided with cup-shaped recesses in which is deposited the plastics material and thermally treating the web in one more stage to cause the plastics material to be sintered to the web. Used for coating thermally sensitive textile webs with designs. The webs are coated with a pattern of dots at considerably reduced temp and increased prodn. rate is obtd.
