Abstract: A process for manufacturing a material from a greaseproof paper used as support. At least one face of the support is coated with water or at least one aqueous solution. The support thus becomes a pliable support, The surface of the pliable support is treated by depositing one or more pigmented layers on the surface. This treatment improves the qualities of metallization or of printing or of both of the paper, relative to uncoated greaseproof paper. The pliable support thus becomes a pliable coated support. The pliable coated support is then calendared.

Abstract: Clothing garments and other articles include an elastic laminated sheet having the properties of stretchability and recoverability. The elastic laminated sheet is formed from a nonwoven fibrous web and an elastomeric film laminated to at least one entire web surface. The laminate is incrementally stretched along lines substantially uniformly across its length and width and throughout its depth to form a stretchable and recoverable composite. The elastic laminated sheet is uniquely suited for use in athletic and active wear garments. The composite is also useful for single use or throw away clothing articles such as medical or surgical garments, throw away bathing suits, underpants, undershirts, and garments used in the handling of hazardous or waste materials.

Abstract: The first layer of elastomeric synthetic resin transparent ink is screened onto a transfer sheet and is fused. One or more layers of compatible ink are deposited thereon and dried to form an image. Next, an elastomeric adhesive protective layer is applied and fused. The intermediate article thus produced by this process is a transfer sheet carrying a transfer lamination which is applicable to fabric. The adhesive layer is applied against the fabric with pressure, and the entire structure is heated. During this heating, the elastomeric adhesive is absorbed into the fabric and is cured in place to become thermoplastic. At the same time, the first layer against the transfer sheet becomes plastic and the transfer sheet is removed.In another embodiment, the first and protective layers are fused and an additional elastomeric adhesive layer is applied unfused. During the transfer with the application of heat and pressure, the final layer performs the adhesive function, is absorbed into the fabric, and fuses.
