천연염재를 활용한 일회용 작업복 소재의 기능성 특성 평가

Abstract

The purposes of this study were to investigate characteristic changes on nonwoven fabric by the charcoal and the yellow soil printing. It separate the grind charcoal and the yellow soil as two different size of particles 45~52㎛ and 53~65㎛ for hand screen printing on three kind of nonwoven fabrics. To examine the effect of the charcoal and the yellow soil printing on nonwoven fabric were to observe surface changes by a scanning electron microscope, dyeability by using spectrophotometer, moisture regain by oven method, deodorization and antibacterial activity. The results were as follows: When the charcoal and the yellow soil powder concentration increased from 3 to 9% or from 5 to 10%, K/S value also increased from 3.06 to 8.55 or from 1.14 to 1.80. The charcoal and the yellow soil moisture regain also increased. In same concentration, moisture regain occurred higher as particle of small size. In concentration of charcoal 3%, rate of deodorization measured as 89%, 83% and 87%, and 9% concentration caused 96%, 86% and 93% of high deodorization. In concentration of 5, 10% of yellow soil, rate of deodorization measured as 85% over. Antibacterial activity examination in nonfinished nonwoven fabric resulted range of 60%, however, 3% and 9% concentration finished nonwoven fabric resulted 99.9% of excellent antibacterial activity. Also 5%, 10% yellow soil concentration was appeared same resoult.
