황토 날염을 이용한 일회용 작업복 소재의 쾌적성 및기능성 향상에 관한 연구

Abstract

The purpose of this study were to investigate characteristic changes on nonwoven fabric for disposable work clothes by the yellow soil printing. It separate grind 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 yellow soil printing on nonwoven fabric were to observe, dyeability by using spectrophotometer, moisture regain by oven method, air permeability, anion property and antibacterial activity. The results were as follows: When yellow soil concentration increased from 5 to 10%, K/S value also increased from 1.05 to 1.88. When yellow soil concentration increased, moisture regain also increased. In same concentration, moisture regain occurred higher as particle of small size. Air permeability decreased when the charcoal printing concentration increased. Anion occurrence appeared 140～160ion/cc from three different kinds of nonwoven fabrics in 3% and 9% yellow soil concentration. Therefore, occurred anion ineffectively. In concentration of 3%, rate of deodorization measured as 89%, 83% and 87%, and 9% concentration caused 96%, 86% and 93% of high deodorization. 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. Surface temperature increased 1.5～2℃ by yellow soil finishing.
