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 $45\sim52{\mu}m$ and $53\sim65{\mu}m$ 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 $140\sim160ion/cc$ 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 $1.5\sim2^{\circ}C$ by yellow soil finishing.

This study analyzes the actual state of the working uniforms worn by burning waste workers to protect their body from the hazardous environment. Directions for improvement of the clothing fabrics is also suggested. We visited and interviewed those persons who worked in the burning waste plant in Seoul and in Gyunggi Province. 245 workers were surveyed by questionnaires, and 211 workers out of 245 were statistically analyzed. Frequencies and percentages were calculated and $\chi$$^2$ test, ANOVA and Scheffe Post hoc comparison methods were utilized to test some hypothesis. The working uniforms were classified as four general types: separate type, disposable-coverall. overall, and winter clothes. At present, the working uniforms are not suitable for the conditions which they are used. There is a lack of ventilation and an inability to absorb perspiration limited elasticity, and the uniforms are prone to static shock. The degree of satisfaction varied significantly, based on the worker's educational background and main work. However, only a small percentage of workers interviewed were satisfied with the appearance and the fit of the present working uniforms. The working duration had a negative impact on the satisfaction of the worker. This results suggest that materials, colors, design and size of working clothes must be improved. The suggestions are as follows: Firstly. to use disposable non-woven fabrics finished to increase moisture regain. Secondly. to use the bad air permeability fabrics to protect the skin from absorbtion of harmful gases, flying dust, heavy metals, etc.

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 $45{\sim}52{\mu}m\;and\;53{\sim}65{\mu}m$ 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.

Protective coveralls are very uncomfortable to work in comparison to ordinary top and bottom separated clothing. A pattern maker has to consider the size of the human body and human motion range when designing protective coverall patterns. It is difficult to produce well-fitted coveralls because of the lack of readymade patterns despite the increased need for protective coveralls at various jobs. Patterns are decomposed by unsewing 18 products in the domestic market to provide the fundamental information on developing patterns for protective coveralls. The characteristics and differences of pattern types are compared after grouping patterns with information taken from the analysis of the shapes and measurements of patterns from the acquired patterns. The results of the analysis showed that on-market protective coveralls were less curved but much linear when compared to ordinary clothing patterns; however, the breasts and crotch circumferences were very loose and bulky, which is quite different from the other all-in one style working clothes. For the pattern shapes, patterns are classified into waistline-seamed and bustline-seamed types. The result of the hierarchical cluster analysis with 27 measurement variables were classified into four groups. Types by shape and measurements were related to each other; therefore, we expect the information of each type to be used in developing protective clothing patterns.
