  • Cotton fabrics were treated with some commercial non-formaldehyde and low-formaldehyde resins, and then their effect on the physicochemical properties were respectively investigated including formaldehyde release, tear strength, shrinkage, and wrinkle recovery. Formaldehyde release less than 10ppm was obtained only by non-formaldehyde resin. Considering other factors, the optimal concentration of non-formaldehyde resin was shown to be 9-11%. In case of low-formaldehyde type, 5-7% resin concentration and curing temperature of $160{\sim}170^{\circ}C$ were recommended for optimal finishing condition. The choice and combination of resins and catalysts were also important factors, and preliminary considerations before treating cotton fabrics with resins used in this study are also important to get much better results.

  • The removal and redeposition of particulate soil occur simultaneously during the washing process. In order to investigate variables which affect on the redeposition of particulate soil, cotton lawn was soiled in the ion oxide black suspension using Launder-O meter. The amount of deposited soil was estimated by means of the spectrometric analysis of iron on the fabric after soiled. The results are as follows: 1. The presence of surfactants b suspension decreased the deposition of particulate soil and the most effective surfactant was soap and the descending order was NaDBS>CTAB>PONPE. 2. The influnce of temperature on soil deposition was considerable, soil deposition was gradually increased with elevating temperature in ionic surfactants solution such as NaDBS and CTAB but that was decreased above $40^{\circ}C$ in nonionic surfactant solution. 3. The tendency of soil deposition was dwindled by adding electrolytes especially in case of polyvalent anions. 4. From the results of the experiments redeposition of particulate soil was related with suspending power of surfactants and was influenced by factors varing zeta potential.

  • This study studies the fabrics from excavated 17th century tombs of Mrs. Min from Yeoheung family(1586~1656), Yeo-on Kim(1596~1665) and Won-rip Choi(1618~1690) and attempts to clarify the relationship between the fashion trend in fabrics of those times and the background behind it by viewing and examining the proportion of twill fabrics to the total silk fabrics and the characteristics of its weave and patterns. Looking into fabrics from the above tombs, twill fabrics accounted for 10.4%(13 pieces) 19.3%(16 pieces) and 9.2%(9 pieces) of total silk fabrics in each of the respective tombs. This forms a remarkable contrast with the fact that there was only one piece of twill silk fabrics(0.5%) and not any from the 16th century tombs of Mrs. Yoon from Papyeong family (0.5%) and Soo-ryoon Sim(0%). In particular, the percentage of hwamun-neung(patterned twill fabrics) in each of the tombs is 8.0%(10 pieces), 13.3%(11 pieces), 9.2%(9 pieces), which is much higher than that of non-patterned one. This is common to the twill fabrics from above three 17th century tombs. Patterns of hwamun-neung(patterned twill), simplified small flower patterns or geometrical figures, from the three excavated tombs are mostly arranged sporadically with blank space. It is supposed that these figurative characteristics reflected the aesthetic sense of the gentry at that time which valued simplicity and moderation for their Confucian standard. This phenomenon of increased use and production of twill fabrics in the 17th century resulted from different factors such as wars like Japanese Invasion of Korea(1592~1598), economic difficulty, government regulations against the production of high-class fabrics, development of weaving skill and its fixation, changes of fabric production environments, and changes of aesthetic sense preferring naive and moderate things to showy ones. As for the weaving characteristics of twill fabrics from the three 17th century tombs 3 leaf warp-faced twill was often used for the ground texture and 4 leaf warp-faced one was occasionally used. For pattern texture 6 leaf weft-faced twill was frequently used, 4 leaf weft-faced twill and 3 leaf weft-faced twill were used at times, and floating one was occasionally used as well.

  • This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issues with using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easily and sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.

  • In this study, we have compared the relative importance of various washing condition affecting on soil release for P/C blended fabrics. P/C blended fabrics were soiled by the pad-dry method with aqueous and oily soil. The washing procedures of soiled samples were performed by Atlas Launder-Ometer with 27 wash conditions which are combinations of wash temp. wash time and detergent cone. The degree of soil-release was evaluated with CIE 1976 Lab color difference before and after washing. Multiple regression analysis was used to evaluate the optimum wash conditions and the relative importance of the factors providing maximum soilremoval.

  • Peroxodisulfates are being developed as low temperature bleaching agents for cotton fabrics to save the thermal energy. In this research we used the colar difference meter to determine the whiteness which peroxide booster will possibly make an effect on cotton fabric at the low temperature process using consist of temperature with different conditions agents, such as sodium hydroxide, sodium peroxodisulfate and potassium peroxodisulfate. The peroxide bleaching follows a laboratory experiments, using a statistical plan for three variables: the concentrations of hydrogen peroxide and sodium hydroxide and the temperature of bathing. The purpose of this research was to use the response surface analysis method to evaluate the relative importance of factors providing optimum whiteness. A ridge analysis of the data on whiteness response results in 3-D response surface diagrams for optimizing the concentrations of hydrogen peroxide and sodium hydroxide at about 42~52$^{\circ}C$.

  • The purpose of this study was to make a scale for measuring the subjective hand of fabrics. For this purpose subjective hand expressions which were published in the journals were reviewed. 11 pairs(9 biopolar-pairs, 2 unipolar-pairs) were selected after searching the definitions in a dictionary followed by focus group interview and survey. To find out if these terminological biopolar pairs are agreed with the biopolar pairs in human sensation, a survey of fabric hand was undertaken using a scale consisted of 20 words(18 words from biopolar-pairs, 2 words from unipolar pairs). Among 11 pairs, 10 pairs except [taktakhada-poksinhada] were accepted as biopolar pair of word terminologically and sensuously. [taktakhada-poksinhada] was recognized as a biopolar pair terminologically but not sensuously. These 20 words were classified as 5 factors-surface contour, density, flexibility, dampness, and extensibility
