숯 날염에 의한 부직포의 특성 변화 = Characteristic Changes on Nonwoven Fabric by Charcoal Printing

다국어 초록 (Multilingual Abstract)

The purposes of this study were to investigate characteristic changes on nonwoven fabric by the charcoal printing. It separate grind charcoal 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 charcoal printing on nonwoven fabric were to obwerve surface changes by a scanning electron microscope, dyeability by using spectrophotometer, moisture regain by oven method, air permeability, anion property, deodorization and antibacterial activity. The results were as follows: When charcoal powder concentration increased from 3 to 9%, K/S value also increased from 3.06to 8.55. When charcoal 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/㏄ from three different kinds of nonwoven fabrics in 3% and 9% charcoal 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.
