  • Diffusion/penetration rates of finishing agents are not a major criterion in the design of low molecular weight finishing agents. However, in the case of polymeric finishing agents, high molecular weights result in large hydrodynamic volumes and diffusion/penetration of the finishing agent into the substrate may become a critical factor in the design of textile finishing agents. Thus the effect of the molecular weight of a model compound, polyethylene glycol, on its diffusion through a cellulose membrane or cotton fabric is studied. Diffusion experiments of polyethylene glycol of molecular weight 400, 1000, 2000, 4600, 8000, and 10000 through cellulose membrane or fabric was carried out in a glass U-tube diffusion apparatus and the half penetration times and the penetration coefficients were determined. Both the half penetration times and the penetration coefficients exhibited a significant change between molecular weight 2000 and 2500 as the molecular weight of polyethylene glycol increased, suggesting that there is a critical molecular weight above which diffusion/penetration becomes difficult. Based on this study on a model compound, it is suggested that polymeric textile finishing agents can be expected to exhibit similar behavior.

  • The main purpose of this study was to examine the sectors of Korean textile complex based on various economic characteristics and performances. The sectors in the textile complex differed in many aspects. Man-made fiber industry showed capital-intensive characteristics even though most of the sectors in the textile complex were labor-intensive. Textile industry is composed of weaving and spinning, knitting, dyeing and finishing sectors and even within the textile industry, each sector had different characteristics from each others. Weaving and spinning sector seemed to require relatively high capital investment, while dyeing and finishing was very labor-intensive. Labor-intensive apparel industry has faced decrease in labor-productivity while wage has increased. Slow growth in labor productivity in Korean textile complex was shown to be a more problem than increase in wage or ratio of labor cost to value added. Apparel companies appeared to be in better financial states than the textile companies, even though the exports of apparel products have decreased in the 1990s. However, in overall the financial states of the Korean textile complex were not as strong as those of the other manufacturing sectors.

  • Research information related to application of enzyme as pretreatment and subsequent functional finishing on wool blended textiles for imparting multi-functional properties is still scanty. Yarn-blended wool/cotton fabric was pretreated with both a cellulase (Bactosol-CA) or a protease (Savinase-16.0LEx) in individual, subsequently finished with Synthappret-BAP and ${\beta}$-cyclodextrin based combination to impart anti-shrink, anti-microbial, softening and anti-crease properties. The performance of the finished fabrics depended on type of finishing combinations applied rather than enzyme pretreatment. Savinase pretreatment followed by Synthappret+Ceraperm-MW combination finishing impart both anti-shrink property as well as softening, while Bactosol pretreatment followed by ${\beta}$-cyclodextrin and sanitize combination finishing impart antimicrobial activity as well as anti-shrink finish to the wool/cotton blend fabric.

  • Silk textile finishing has been studied for many years by many workers in order to meet more utilities for various endusers. Such studies, however, could not be successful because any natural fibers are hardly change their natures by artificial treating methods. Textile finishing is of course to improve the mechandise qualities and the poor natures of silk so that it may be available as the best textile fiber in the world. Sometimes, famous trade marked textile plays more power than its quality in the silk market, nevertheless, this should be over line of research activities. Meantime, the silk demand has been also transferred from ladies stocking to other clothes since nylon or other synthetic fibers were developed. That is why, the extension of silk demand should be developed by various research works. Specially, silk is known as difficult textile to handle it during washing or ironing process which happened to depress down the silk usage for house wives. In order to solve such problems, the reporter has been worked for many years and now, he believes that he has developed a proper finishing method to coversuch problems. The developed finishing method may be said to eligible with economical aspect and shorten the dry duration after water washing in half against normal silk textile without harming the specific silk nature. As all of us know, silk fiber starts to denature since it was spinned by silkworm and the fiber is formed as overlapped "S" type curves during its concooning process. After it is made as raw silk or sericin silk, it shows as straight line form, but it changes in to waved form in case refining or degumming process in order return to its original spinned form. Such nature is continued during its textile form and ends with hard ironing nature than other textile fibers. Mean while, the silk fiber keeps to continue its denaturing and this is iniciated by repeat of washing and drying which takes many years to reach its final stage, The reporter has found the iniciating denature of silk by his finishing process, with out heat, decreasing the swollen nature which ended with shortening the drying duration after wash. Each washing was carried out by soaking the previously weighed sample in cold water for one hour, then pressed the sample for ten minutes to eliminate its free water component before weighing with same condition. According to this, the treated silk showed much denaturing after the finishing, but the standard silk progressed the denaturing by and by with the repeat of washing and drying, finally reached the same swollen degree of treated silk, Such treating result explains that the treated silk happened to be stebilized nature by the treating immediately. On the other that the treated silk happened to be stebilized nature by the treating immediately. On the other hand, standard silk may reach to such condition by the time of worn out clothes after repeat of washing and drying for many years while the clothes will be no more useful. The decreased swelling nature has brought about the drying period in half against standard silk after all. Not only the tests of tenacity and elongation but also crease resistance recovery, stiffness and shrinkage tests were carried out after each washing and drying which he has found better result on the treated silk textile against the standard silk. The most important thing was to keep the textile feeling of silk by such finishing work before improve any poor nature of silk. The general silk has a nature to absorb smoke or dirt from its surrounding air and reaches to dirty color shade upon such exposure, but the treated one has improved such nature because of its artificial denaturing, another word, it keeps clean longer than the normal silk. Many previous finishing works could improve some specific nature of silk, but it happened to deprave other important natures. The reporters work is, however, specialized to improve the silk to be useful as Wash and Wear Silk without harming its standard natures. So far, this work happened to be a overall innovative finishing method of silk textile.

  • First of all, the properties imparted to PET fabrics are resistance to and recovery from creasing or wrinkling when wet or dry; high resistance to stretch in the filament yarns but not in the staple; high abrasion resistance; good texture and appearance; resistance to heat ageing; good chemical resistance and good resistance, behind glass, to sunlight. But, the low moisture regain of PET fabric conduces to static troubles in textile processing. Furthermore, garments made from PET may, during wear, develop electric charges which attract to the fabric particles of soil(dirt, swarf, dust) flying in the air, so that the cuffs of shirts, for example, become soiled quickly and are not easily laundered clean. The sericin constitutes 25$\sim$30% of silk protein and surrounds the fibroin fiber with sticky layer that supports the formation of a cocoon. The useful biochemical properties of sericin protein are oxidation resistant, antibacterial, UV resistant, hydrophilic property, and good affinity with hydrophobic material. These properties can be used as an improving reagent or a coating agent for natural and synthetic fibers, fabrics, and other intermediate products. The sericin is also applied to cross-link, and can be blended with other materials. In this study, we modified the surface of PET fabric by mixture of sericin finishing agent; sericin, polyuretane binder and 1,2,3,4-butanetetracarboxylic acid (BTCA) cross-link agent. Also, we investigated the finshing effect; moisture regain, stiffness, handle, drape and electrostatic. The moisture regain of PET fabric treated with sericin finishing agent was higher than that of untreated PET fabric. As a result of evaluating influence about handle of PET fabrics treated with sericin finishing agent, it was confirmed that the sericin finishing agent could be use as a linen like finishing agent.

  • To obtain the basic data of the effect of antimicrobic finishing on chrome-tanned leather for apparel, it was studied that the specimens given from each step of manufacturing process, that is, steps before and after neutralization and after fixation were treated with Si-QAC as a antimicrobic finishing agent, and the antimicrobic activity was evaluated. The results were as follows: 1. The bacterial reduction of the specimens finished antimicrobically were 100% and 94.4% before and after neutralization respectively, however, the specimens carried out successive process after antimicrobic finishing exhibited the reduction of 16.5% and 14.8%. It was assumed that the antimicrobic agent was washed off by the successive process. 2. When the antimicrobic finishing was carried out on the specimens after fixation the bacterial reduction was 95.0% and then the specimen carried out successive process was 97.3%. This result indicates that antimicrobic finishing on the leather would be given after fixation rather than before and after neutralization.

  • Shrink resist finishing of wool fabric was carried out with Monoethanol aminesulphite (MONAMIN BTN) shrink resist agent after chlorination with Dichloro isocyanuric acid (DCCA). The purpose of this study is to investigate the effect of treating conditions, such as concentrations of DCCA and MONAMIN BTN, pH of treating bath, dyeing times, curing times and temperatures, on dyeing property of wool fabrics. K/S values and fastness properties of dyed wool fabrics were measured. The K/S values of dyed fabrics were increased gradually with increasing concentration, and decreased with increasing curing time. The optimum dyeing time and curing temperature were 60 min and $140^{\circ}C$, respectively. Also it seems likely that the shrink resist finishing carried out at 3% (o.w.f.) of MONAMIN BTN and pH 7 of resin treating bath is effective in increasing K/S values. Light fastness of fabric dyed was very poor and the fastness of fabric dyed was not influenced by the treatment conditions.
