Abstract
Abstract A process for manufacturing transfer sheets is disclosed in which short fibers are temporarily stuck to a base sheet to form a short fiber layer to which two kinds of adhesives are applied to a desired design or letter to be transferred. When the transfer sheet thus made is put on a clothes or the like and heat and pressure are applied, the short fibers are transferred to the clothes only where coated with the adhesive.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
105 words
A process for manufacturing transfer sheets comprising the steps of: forming on the surface of a base sheet an adhesive layer for temporary adhesion of short fibers, to the base sheet, temporarily sticking short fibers to said adhesive layer to form a short fiber layer, applying an adhesive in the form of emulsion or solution in said short fiber layer to a desired pattern to form a transfer adhesive layer, bonding the upper part of said fibers in said pattern said adhesive retaining elasticity after curing, and applying a heat-sensitive adhesive in powdery form to said transfer adhesive layer before the transfer adhesive has cured.
Claim 2
Dependent Claim
105 words
A process for manufacturing transfer sheets comprising the steps of: forming on the surface of a base sheet an adhesive layer for temporary adhesion of short fibers, to the base sheet, temporarily sticking short fibers to said adhesive layer to form a short fiber layer, applying an adhesive in the form of emulsion or solution in said short fiber layer to a desired pattern to form a transfer adhesive layer, bonding the upper part of said fibers in said pattern said adhesive retaining elasticity after curing, and applying a heat-sensitive adhesive in powdery form to said transfer adhesive layer before the transfer adhesive has cured.
Claim 3
Dependent Claim
27 words
A process for manufacturing transfer sheets as claimed in claim 1 wherein the short fiber layer is formed in a pattern slightly larger than said desired pattern.
Claim 4
Dependent Claim
44 words
A process for manufacturing transfer sheets as claimed in claim 1 or 2 wherein short fibers of a light color are used to form said short fiber layer and are colored after formation of said short fiber layer to at least one other color.
