[Study of the pulsation method for the hygienic treatment of underwear].

Hygienic processing of the underwear in a device combining mechanical treatment, forced pumping of the washing solution and wringing by compressed air can be used under special conditions. The basic parameters of the engineering process have been determined, viz.: the number of washing baths, temperature of the water, time of processing, etc.

[Hygienic evaluation of experimental samples of antimicrobial underwear containing hexachlorophene].

The hygienic examination of 12 samples of knitted underwear which contained hexachlorophene added during fiber formation allowed the selection of four types that can be used under poor sanitation conditions. Taking into consideration possible changes in the proportion of various micoorganisms during prolonged space flights, it is recommended to carry out a complex investigation in order to allow the use of the antimicrobial underwear by specific crewmembers during a certain period of time.
