Researches were made on foot-warming, anti-bacteria and deodorant treatment. Feet, the very important organ to human body, perspire much and their temperature is lower than those of other parts. Hence, keeping feet warm, sanitary and deodorant is the area of this study. Latex sponge of activated carbon, impregnated open cell foam, treated with Vikol DZ-anti-bacteria finishing agent, was developed and tested for warmth-keeping by KSK 0560 test method and for sanitization by AATCC 90 HALO test method and for deodorization by wearing tests. The results show that the new developed latex spongee has warmth-keeping ratio of 2.5 times higher than that of the conventional spong and it has an excellent anti-bacteria effect. Actual wearing function tests also show that it improves significantly the performance of deodorization, sanitization, warmth-keeping and bulkiness.
