ABSTRACT:
This invention relates to a hot melt adhesive which is particularly useful for securing textile substrates together. The hot melt adhesives of this invention are crystallizable copolyesters which are comprised of repeat units which are derived from terephthalic acid, isophthalic acid, ethylene glycol, and hexamethylene glycol. They normally have melting points within the range of about 95.degree. C. to about 125.degree. C. and glass transition temperatures within the range of about 0.degree. C. to about 10.degree. C. This invention is also related to a process for securing substrates to one another by utilizing such hot melt adhesives.
