  • In the present research to evalulate the chemical composition of wool under Korean feeding conditions have been investicated. The experiment was designed two treatments (washed and non-washed wool) and devided inner and outer side wool each treatment. The criteria for evaluation of wool with chemical composition were protein, fat, ash, amino acid and mineral content. The results which were obtained as follows: 1. Average protein content of non-washed and washed wool were 76.05% and 92.31%, respectively. However it was not different in protein content between inner and outer side wool. 2. Average fat content of non-washed and washed wool were 12.43% and 5.77%, respectively. However inner side wool was more fat content than outer side wool. 3. Average ash content of non-washed and washed wool were 10.50% and 0.90%, respectively. However inner side wool was less ash content than outer side wool. 4. Amino acid composition was not different between inner side and outer side wool. However lysine, arginine, proline, and glycine content of inner side wool were higher than those of outer side wool. 5. Mineral content of non -washed wool were higher than those of washed wool. Potassium content of non-washed wool was very high compare with that of washed wool.

  • In the wool textile industry, the necessity for technology development has been steadily raised to create improved fineness and yarn count of existing wool yarns with thick fineness for ensuring higher quality grades of wool yarn. Recently, through controlling fineness of wool yarn for making finer wool in relation with environmentally-friendly and high-sensitivity trend, a differentiated continuous drawing process where the quality of wool can be artificially manipulated has been suggested in the latest textile industry. This study investigated the basic conditions during the continuous drawing process which enable to manufacture wool yarn with fine count by controlling reducing agent treatment, physical drawing and drying after reducing agent treatment, and oxidizing agent post-treatment conditions. Furthermore, this study reviewed the drawing effects by applying the basic conditions for reduction and oxidation reaction in the drawing processes of wool/cashmere, wool/silk, wool/polyester blended yarns as well as such wool yarns. Also, in order to review the practicability, this study examined the physical properties and dyeability of drawn wool yarn applied textile materials in comparison with normal wool yarn applied textile materials.

  • Recently the demand for wool has been gradually decreasing due to global warming, oil depletion, Coolbiz campaign to reduce CO2 emission, and preference for business casual wear, while the price for wool materials has been constantly increasing. Wool, characterized by the natural touch and unique sensibility, is considered as one of the best natural materials, including silk. For wool, currently Korea almost depends on import from foreign countries. Therefore, 100% wool products cannot be competitive in terms of pricing and current trend. To secure sustaining competitiveness in the fiber market, it is required not only to develop new wool materials that enable expression of new sensibility that cannot be expressed by conventional wool fibers, but also to pursue differentiation of fundamental sensibility and functionality by highlighting advantages for wool as a natural fiber but by reducing its disadvantages through dominant conjugation with synthetic fibers. This study attempted to improve the technology of differentiating wool-like synthetic fibers such as polyester and combine technology with sensibility through mixing with wool materials. It also aimed to develop wool-like stretch materials and pre-treating and yarn dyeing technologies that enable fabrics to main natural wool-like touch and stretch, and ultimately to develop wool mixed fabrics that have new sensibility and functionality.

  • The purpose of this study was to select high-quality boar semen after the glass wool filtration of extended boar semen. After collecting boar semen, its concentration, morphology, viability, and motility were examined according the glass wool's height and time. After glass wool filtration, the sperm concentration decreased, but the proportion of normal sperms and the sperm viability increased. Nevertheless, the sperm motility showed no changes. The above results showed that the glass wool filtration of boar semen is a method of obtaining sperms with relatively low abnormal rates and high viabilities.

  • For the modification of wool surface, wool fabrics treated with oxygen low-temperature plasma(LTP) and dichloroisocyanuric acid(DCCA) were dyed with milling type acid dye. The difference of dyeing properties on modified and control wool fabric were investigated. DCCA treated wool showed that saturation dye uptake and dyeing desorption ratio were higher than LTP treated wool. Dyeing transition temperatures of DCCA and LTP treated wool fabrics were 20$^{\circ}C$ degree lower than control wool fabric. In light color fastness test, DCCA treated wool fabric was 1 grade lower than LTP or control wool fabric.

  • The dye permeability of the chlorinated wool has been discussed in connect with dye constitution and water absorbency. The chlorinated wool tends to increase the water absorbency and the degree of swelling, which affect to the dye permeability. The mixture of equal parts of chlorinated wool and normal wool were dyed with simple acid dyes which differ in the number of sulphonic acid groups. It is confirmed that the ratio of dye take up by normal wool and chlorinated wool increases with increasing sulphonated groups of dye and the rate of dyeing decreases with increasing basicity of simple acid dye as elucidated by Townend and Simpson for dry-chlorinated wool.

  • The effects of the low temperature plasma and chitosan treatments on the shrink resistant properties and hand of wool fabrics have been studied. When the plasma treatment was carried out on the wool fabrics, the cuticle of the wool fabrics seemed to be damaged; especially at 150 W power, it was observed that the scales were broken. Therefore the structural changes of the wool fabrics decreased the felting shrinkage of the wool fabrics. Howerver, the plasma treated wool fabrics showed harsher handle compared to untreated wool fabrics. When the plasma pretreatment was applied on the wool fabrics, then water soluble chitosan was coated on the surface of wool fibers uniformly, the shrink resistance of the wool fabrics was enhanced. The plasma-chitosan treatment also affected the mechanical properties and hand values of the wool fabrics.

  • In this study, wool/nylon(50/50%) blend yarn and its fabrics for tra-biz(complex word of travel+business) garment were prepared, and its wear comfort characteristics were investigated through thermal manikin and human-body wearing experiment. In addition, tactile wearing performance from fabric mechanical properties and the dimensional stability and the pilling of the fabric specimen during wearing and dry-cleaning were measured and compared with those of wool 100% fabric specimen. Heat keepability of the wool/nylon(50/50%) blend fabric by thermal manikin experiment was superior than that of wool 100% fabric, this result was verified with human-body wearing experiment and its result coincided well with this experimental result. Tactile wearing performance of the wool/nylon(50/50%) fabric from fabric mechanical properties measured by FAST system was better than that of the wool 100% fabric. The dimensional stability of the wool/nylon(50/50%) fabric was more stable than that of the wool 100% fabric. Because relaxation shrinkage was lower and hygral expansion of wool 100% fabric was more high. However, the breathability and pilling property of the wool/nylon(50/50%) fabric were inferior than those of the wool 100% fabric. The possibility of application for tra-biz garment of wool/nylon(50/50%) blend fabric was observed because of good heat keepability, tactile wearing performance and washing fastness.

  • The fineness of wool fiber is the most important factor in deciding quality. Recently, the demand of fine denier wool has increased but it is relatively expensive because of the manufacturing cost. In this study, a machine, controlling the fineness of wool fibers, was designed and manufactured to prepare fine denier wool. By easily controlling the fineness of wool fiber by elongating the wool sliver, the manufacturing costs of spun yarn can be reduced to eliminate the cost burden of high-quality wool fibers.

  • Adsorption behavior of hydrolyzed wool keratins onto wool fabric was first studied systematically for the purpose of improving the permanent set of a wool fabric. The adsorption isotherm of the keratin onto wool fabric showed a Langmuir type and was found to be influenced by pretreatments such as swelling and reduction of wool fabric. Indeed, by the reduction, the diffusion coefficient of the hydrolyzed keratin was increased by about 10 times as large as that of the untreated wool fabric. It was indicated from the solubility test and washing test that new crosslinks were possibly formed by the adsorption of keratin and the subsequent oxidation. Dyeing behavior of the keratin adsorbed wool fabric was also discussed in terms of the adsorbed amount of hydrolyzed keratin.
