유기향균제를 이용한 타올의 향균가공에 관한 연구

Study on the Antimicrobial Finishing of Towel by using Organic Antimicrobials

유기실리콘 제4급 암모늄염을 이용하여 타올에 향균제를 처리하였을 때의 향균성에 가장 많은 영향을 미치는 처리농도, 시간, 온도에 대한 향균성 변화를 비교 조사하였고, 향균처리 후 물성변화, 내세탁성을 측정하였다. 타올의 향균성에 가장 우수한 향균성을 나타내고 많은 영향을 미치는 처리농도는 3.5%이며, 처리온도 $30^{\circ}C$에서, 처리시간 10분간 향균가공 처리하여도 균감소율이 95% 이상 향균성능을 유지함을 알 수 있었다. 또한 세탁 횟수에 따른 균 감소율은 20회까지 세탁하여도 80%이상 높은 향균성을 나타내었고, 향균제 가공처리 후 측정한 타올의 인장강도 및 신도는 큰 변화가 없었다.

The study was investigated to the effect of antimicrobial finishing of towel treated by organic antimicrobial agent. It was measured for the optimal condition such as treated time, treated concentration and temperature. After amtimicrobial treatment, mechanical and fastness properties, anti-laundering property were measured.The antimicrobial activity of samples was analyzed quantitatively by masureing the number of colonies of Staphylococcus aureus using the shake flask method. Towel samples treated with the optimal condition such as treated time of 10 minute, and treated temperature of $30^{\circ}C$, concentration of organic antimicrobial agent of 3.5% were shown a high reduction rate in the number of colonies grown and clear zones of inhibition.The effect of reduction rate for laundering until the number of 20 times was shown high reduction rate of over 80%. And the mechanical properties of samples treated with organic antimicrobial agent were not changed approximately.
