摘要：
A dimensionally stable polyester melt blown web composition is disclosed. The polyester melt blown web is obtained by contacting the web with a solvent, and drying the web. The solvents which are used have total solubility parameters (S.sub.o) of 8.5 to 12.0 (cal/cm.sup.3).sup.1/2, solubility parameter component due to hydrogen bonding (S.sub.h) of 0.5 to 5.5 (cal/cm.sup.3).sup.1/2 and solubility parameter component due to polar forces (S.sub.p) of 0.5 to 7.0 (cal/cm.sup.3).sup.1/2). The polyesters used for such melt blown webs include poly(ethylene-terephthalate), poly(cyclohexylene dimethylene terephthalate) and blends and copolymers of these polymers.
