Plastic athletic lettering material and process for manufacturing same
Abstract
Abstract Flexible plastic sheet material is provided from which pigmented letters, designs and the like may be cut for fusing to fabrics. A liquid pigmented mass of heat curable plastic, for example, plastisol, is knife-spread on a high gloss release sheet and heat cured, to serve as the outer, pigmented side of the sheet material to be formed. An unpigmented preformed flexible thermoplastic sheet, whose fusing temperature is lower than the temperature of heat curing, is pressed to the newly cured, hot pigmented film and fused to it; this thermoplastic serves as the inner adherent side of the material. Letters and designs cut from such material may be ironed onto fabric, utilizing heat sufficient to raise the inner, thermoplastic side to fusing temperature without affecting the outer, pigmented side.
