The dying properties of fabrics with Chaenomelis Fructus extract were studied through an investigation of the characteristic of Chaenomelis Fructus colorants, the effect of dyeing conditions (dye temperature, dyeing concentration, and times on dye uptakes), effect of mordant, effect of UV irradiation, and color change in addition, antimicrobial ability and deodorant ability were estimated. In the UV-Visible spectrum, the wavelength of maximum absorption of Chaenomelis Fructus extract was 280 nm and showed that tannin is the major pigment component. From the increase of absorbance by UV irradiation, it was assumed that catechol tannin color was developed through UV irradiation. An increased dyeing concentration resulted in a larger dye uptake. Dye uptake increased as the dyeing time and temperature increased. Chaenomelis Fructus extract showed relatively good affinity to silk than cotton. Mordant, Fe and Cu were effective to increase the dye uptake of cotton fabric in addition, the dye uptake of silk fabric mordanted with Fe and K improved. UV irradiation let the color of dyed fabrics develop regardless of the UV irradiation stage however, UV irradiation on the dyed fabric was more effective than on the extract for the color development. Dyed silk fabric showed very good antimicrobial abilities of 99.9% in addition, deodorant ability improved in the fabric dyed with Chaenomelis Fructus extract.

This research evaluates the change of the water absorbency and drying speed of a quick-drying knit fabric by repeated laundering and laundering conditions and investigates the influence of laundering conditions on the functional properties of the knit fabric. Four factors of laundering conditions were studied: detergent, water hardness, water temperature, and frequency of rotation. Knit fabrics were washed for 25 laundering cycles in a drum-type washing machine with nine different laundering conditions derived from an orthogonal array. The properties of knit fabrics were measured with a drop absorption test, a strip test, and a drying time test. Relaxation shrinkage pointed to a change in the structural characteristics of the knit fabric. Wetting time was faster and wickability was greater in the knit fabrics that underwent 5 laundering cycles; in addition, there were no obvious changes in wetting time and wickability. The detergent was the most important factor in wetting time (40.4%) and wickability (60% or above). Water hardness, water temperature and RPM had less of an effect on wetting time and wickability. There were no significant differences between the levels of laundering conditions (except for detergent) on wetting time and wickability. Drying times with neutral and alkali were slower by repeated laundering; however, there was no obvious change in drying time. Hardness, water temperature and RPM had less of an impact on drying time.

In order to enhance the functionality of a cotton fabric actually used as a clothing material for patients, the fabrics were treated with a chitosan/nanosilver mixed solution. The nanosilver had excellent biocompatibility, provided expectation of an additional performance, did not harm human beings, and supplements chitosan, which was disadvantaged if used alone for fabric treatment. The nanosilver was mixed thereto and a treatment effect due to a mixing ratio was considered. This study was observed through mechanical properties and hand value which were the important function. The treatment of chitosan/nanosilver mixed solution gave a smoother surface than the treatment of chitosan alone. As a result of evaluation of the forms according to KES-FB system, Koshi was deduced, and both Numeri and Fukurami were increased. Thereby, the cotton fabric was a little smooth to provide elasticity, due to the treatment of chitosan/nanosilver mixed solution. THV of the treated fabrics calculated from this basis increased at all mixing ratio as compared with the untreated fabric. The fabrics treated with chitosan/nanosilver mixed solution were shown a better THV than the fabric treated with chitosan alone.

Hollow filament yarns provide better warmth to the touch, lighter in weight, increased opacity, and subtle luster compared to the regular synthetic filament yarns. However, luster properties of textile fibers or fabrics are often difficult to characterize, partly due to the fineness of the surface texture, the anisotropic nature of the weave structure, the complexity of the fiber array comprising a yarn, and the fiber structure itself. In this study, the fabric surface luster image was analyzed using image analysis methods after image acquisition. The hollow filament fiber was modeled using a three-dimensional modeling software. It was then ray-traced for comparing the virtual luster images of the hollow fiber and the regular fiber models based on shading models including photon mapping. The luster object size of the actual hollow filament fabric was smaller than that of the regular filament fabric. The shape of the luster object of the hollow filament fabric was dual peak type while that of the regular filament was single.

In this the study, polyester/cotton(P/C) blended fabrics with fine denier were developed to get the light weight compared with the traditional P/C blended fabrics. Moreover, the width of the fabrics was extended by the tenter during the final heat treatment to get the lower fabric density and lighter weight. Then, the physical properties of these fabrics were analysed. The results were as the follows: The developed fabrics had 22.6-31.6% lighter weight than the traditional fabrics with the same fabric width. The weight of fabric decreased drastically with the fabrics width down to 67.1 $g/m^2$. The fabric density for the warp direction decreased with the fabric width. The tenacity and the elongation of the developed fabrics was little lower than that of the traditional fabrics. The air permeability of the developed fabrics increased with that of the traditional fabrics. The stretch rate of the developed fabrics decreased with increasing the fabric width. Residual stretch rate of the developed fabrics was more stable than that of the traditional fabrics. Residual stretch rate of the developed fabrics increased with the fabric width, but the highest value was less than 5% which is quit stable.

Silicone-coated fabric were treated by oxygen low temperature plasma to improve the adhesion. The surface of silicone-coated fabric was modified with gaseous plasma of several discharge power in the presence of oxygen gas at 1Torr pressure. Oxygen plasma treatment introduces oxygen-containing functional groups and micro-pittings on the silicone-coated fabric surface. The treated fabrics with oxygen low temperature plasma were measured by contact angle analyzer and XPS(X-ray photoelectron spectroscopy), and interfacial adhesion was measured by T-peel test. The surface of fabric was investigated by SEM photographs. The chemical and physical modification of the surface wettabillity by plasma treatment can increase the adhesion.

In general, acid dyes been used for silk dyeing, but acid dyed silk shows weakness in color fastess, To improve this defect, the silk dyed with Acid Mordant Blue 13 was treated with chromes salts solution. Some mechanical properties and dyeing behaviors of the chrome mordant with dyed silk fabric were tested in this work. The tensile strength of silk fabric treated with chrome salts solution was decreased as the duration of treatment was increased. The mean rate constant (K) of photo-degradation was 1.019, and 1.047 after treated with Cr (III) and Cr (Ⅵ), respectively, whereas it was 1.304 in untreatment. The washing fastness of silk fabric also was improved by treatment with mordant and it was 3rd-4th grade and 4th grade when silk was treated with Cr (III) and Cr (Ⅵ), respectively, while untreatment gave 1st grade. The colour of dyed silk fabric was 2.5RP.3/10, but it was 5PB.4/3 and 5PB. 4/4 when the silk fabric was treated with Cr (III) for two hours and with Cr (Ⅵ) for one hour at 90$^{\circ}C$, respectively.
