Abstract
This invention relates to a process for improving the soil release and wetting properties of a polyester textile material by applying thereto a limited amount of an aqueous solution containing about 0.5 to 2.5% by weight of sodium hydroxide and then contacting the textile material with steam while maintaining a moisture content of at least 35% to remove 0.4 to 2.5% by weight of the polyester. By using this procedure the amount of polyester removed is controlled by the limited amount of sodium hydroxide present while at the same time a substantially uniform product is obtained.
