Abstract (en)
[origin: CA2509948A1] A process for treating pantyhose in a cryogenic processor to produce cryogenically treated pantyhose that have enhanced wearing qualities is described. In this regard, one such process, among others, can be broadly summarized by the following steps:reducing the temperature of the pantyhose to between about -80~ C and about -240~ C over about a 1 to 6 hour time period; holding the temperature of the pantyhose between about -80 ~ C and about -24 0 ~ C for a 6 to 48 hour time period; and allowing the pantyhose to increase i n temperature to about 25 ~ C over a 3 to 48 hour time period. The cryogenic treatment of pantyhose results in enhanced wearing qualities.
