摘要： A method for hydroentangling a nonwoven web to increase the strength and abrasion resistance while maintaining highly desirable hand and drape characteristics. The method provides for carding and cross-lapping synthetic and/or natural fibers so as to form a desired substrate. The substrate is then hydroentangled under relatively low pressure to form a desired spunlace web, and a relatively low amount of a foam adhesive latex binding material is applied to the spunlace web. Thereafter, a force is applied to the foamed spunlace web so as to cause the foamed binding material to fully penetrate the spunlace web from face to back. The resulting hydroentangled (spunlace) nonwoven web provides an enhanced balance of tensile properties, abrasion resistance, and fabric aesthetics.

摘要： A continuous process is disclosed for direct esterification of terephthalic acid with ethylene glycol to form low molecular weight polyester with recovery of excess glycol from reaction off-gases. The terephthalic acid is mixed with an excess of glycol, the mixture is reacted at 280.degree.-315.degree. C. in reaction product circulated from a reactor through an external heater and back to the reactor, and reaction product is withdrawn from the reactor for polymerization to high molecular weight polyester. Vapors formed in the reactor are fed into the bottom of a rectification column where the excess glycol is recovered for direct reuse. The vapor feed is sprayed with condensate at 140.degree.-195.degree. C. in the bottom of the column to remove solids and maintain conditions suitable for obtaining less than 0.05 percent glycol in overhead distillate and 0.3 to 10 percent water in glycol condensate.
