Abstract
Abstract Copolyester adhesives are disclosed which are derived from at least 40 mol percent terephthalic acid, up to about 60 mol percent of another dicarboxylic acid selected from isophthalic, succinic, adipic, and glutaric, and a blend of 1,6-hexanediol and diethylene glycol.These copolyesters are useful as adhesives, and especially as fusible interlining adhesives.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A textile fabric laminated to a substrate by means of a fusible interlining adhesive comprising a copolyester derived from at least 40 mol percent terephthalic acid, about 10 to about 90 mole percent 1,6-hexanediol and about 90 to about 10 mol percent diethylene glycol, said copolyester having a crystalline melting point of about 40°-130° C., a glass transition temperature of about -10 to about 30° C. and a heat of fusion of about 1-10 calories per gram.
Claim 2
Dependent Claim
