ABSTRACT:
Fabrics containing at least 50 percent by weight of polyester staple fiber have their pilling propensity greatly reduced by a process that involves (i) atomizing an aqueous solution of certain alkaline saponification agents, such as sodium hydroxide, (ii) applying the atomized solution in controlled amounts to at least one surface of the fabric, and (iii) heating the sprayed fabric to a temperature within the range of 115.degree. C. to 165.degree. C. for about 5 to 120 seconds.
