ABSTRACT:
A method of preparing articles of aetzed embroidery is provided which includes stitching embroideries on a backing of thermoplastic material to form composites, with the backing being either a continuous web or individual sheets. The composites are fed into juxtaposition with a transfer strip having a first side thereof to which the thermoplastic backing material will readily adhere. The composites and the transfer strip are pressed together and heat is simultaneously applied to bring the thermoplastic backing material to its fusing temperature so that the portion thereof covered by the embroideries adheres to the embroideries, and the excess portion of the thermoplastic backing material not covered by the embroideries fuses and adheres to the first side of the transfer strip. Thereafter, the transfer strip and the aetzed embroideries are separated in such a manner that the aetzed embroideries have a thermoplastic backing material adhered thereto, and the excess portion of the thermoplastic backing material remains on the transfer strip.
In a preferred embodiment, the articles of aetzed embroidery are prepared with an adhesive coating on one side thereof and the articles are mounted by the adhesive coatings on a carrier strip for storage thereon and ready removal therefrom. The above-described method is modified to juxtapose a carrier strip having a layer of thermoplastic adhesive on one side thereof with the transfer strip and the embroidery composites are disposed therebetween. Upon application of heat and pressure, the thermoplastic adhesive and the thermoplastic backing material are fused so that the backing material and adhesive covered by the embroideries adheres to the embroideries, and the excess portions not covered by the embroideries adhere to the first side of the transfer strip.
