  • The purpose of this study is to investigate dyeing properties of wool fabric with walnut colorants. Walnut colorants were extracted with water from walnut hull and characterized by FT-IR analysis. Effects of dyeing conditions and mordanting on dyeing properties and colorfastness were studied. Results obtained were as follows, 1. Higher K/S value was obtained at higher temperature and longer dyeing time, the highest K/S value was shown at 100℃, 60min. 2. Dye uptake was increased with the increase in colorants concentration up to 2%. Higher K/S value was obtained at acidic condition. 3. Mordanting was not effective for improving dye uptake and colorfastness and for changing color of the dyed fabric.

  • The purpose of this study was to investigate dyeing properties of silk and wool fabric by Cassia tora extracts according to the conditions such as extraction(temperature time) dyeing(temperature time) condition kinds of mordants temperature of mordanting. The color fastness of laundering irradiation were examined. The results were as follows: The wavelength of maximum absorpthion by extracts appeared at 201, 277, 382nm in UV-Vis spectrum. Absorbance of extracts were increased with temperature and time. The extraction efficiency of Cassia tora was determined as $95^\circ{C}$ of extraction temperature 120 minutes of extraction time. Silk fabric had highest K/S value when dyeing for 90min at $40^\circ{C}$. Wool fabric had highest K/S value when dyeing for 60min at $80^\circ{C}$. Surface color of silk and wool fabric dyed with Cassia tora extracts was 3,9Y and 0.4Y but it was changed from 9.3YR to 7,4Y and from 9.4YR to 5Y by mordants. The fabrics of mordanted by metal ion dyed the depth of color. Laundering and irradiation fastness of mordanted fabrics were improved as compared with nonmordanted fabrics.

  • 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.

  • Treatment of wool fabric with aromatic aldehydes followed by oxidation with hydrogen peroxide gave rise to coloring reaction. The colored fabric was bleached by reduction and recovered the color by oxidation. The oxidation in ethanol solution gave higher k/s values than that in aqueous solution. Photo-stability of the colored fabric was improved by treating with nickel sulfate.

  • The purpose of this study was to investigate the changes of pore area and water vapour transport by the changes of moisture regain and fabric structure of wool fabrics, As specimens 4 worsted wool fabrics were used. The pore area were measured by image analysis method and dinamic vapour transport and water reisitance was determined by clothing-environment-body modelling system. The pore area was changed by the moisture regain of wool fabrics. The change of pore area was influenced by the yarn twist thread count and cover factor and the weave type. The water vapour transport was changed by the moisture regain. The change of water vapour transport was influenced by the change of pore aree which was determined by image analysis.

  • This research aimed to identify the differences, in terms of the pattern, of using wool and jersey for designing jackets and to provide a theorized solution. The object of this study is development of women's tailored jacket pattern by the traits of fabrics with fabrics those are generally used to develop the power of manufacturing technique about fit of jacket. Basic bodies prototype, graphics of sleeves prototype and graphics of jacket pattern those a clothing company at present(on&on, a brand of Beaucre Merchandising Co.,Ltd) is using were used as basics of tailored jacket pattern. Three kinds of fabric(wool, polyester, jersey) were chosen, we made jackets in the same manufacturing process of the clothing company, modified and made up for the weak points and then we compared and analyzed differences of pattern by the traits of fabrics, the results are as follows: 1) We drafted basic tailored style jacket pattern, made a jacket with wool fabric, made wearing experiment, modified and made up for the weak points by the trend, then developed JacketⅠ for study; 2) With JacketⅠ for study as the basic, we made a jacket with polyester fabric, made wearing experiment, modified and made up for the weak points, then developed Jacket II for study; 3) With JacketⅠ for study as the basic, we made a jacket with jersey fabric, made wearing experiment, modified and made up for the weak points, then developed Jacket III for study; 4) We presented final degree of polymerization of pattern with Jacket I II III for study; 5) We compared and analyzed the differences of pattern with the degree of polymerization of pattern with Jacket I(Wool) for study and Jacket II(Polyester), there was no change of size overall except extra amount which happens because of the trait of the fabric in 20 items of body format pattern, there were differences of size in 3 items(height of a sleeve, width of a sleeve, length of a sleeve) among 5 items of sleeves pattern; 6) We compared and analyzed the differences of pattern with the degree of polymerization of pattern with Jacket I(Wool) for study and Jacket III(Jersey) for study, there were differences of size by the kinds of fabric in 11 items(neck point to shoulder point length, Bishoulder point length, back interscye length, front interscye length, armhole circumference, depth of armhole, chest circumference, bust circumference, waist circumference, hip circumference, waist dart) among 20 items of body format pattern, there were differences of size by the kinds of fabric in 5 items(height of a sleeve, circumference of a sleeve, width of a sleeve, length of a sleeve, width of bottom of a sleeve) among 5 items of sleeves pattern.

  • The purpose of this study is to propose scientific data and to develop complex\ulcornermultifunctional fibers by applying microcapsules containing rosewood oil on wool fabric. Polyurea was used as wall material of microcapsules. The parameters for adoptable condition are 20min of agitation time, 5000rpm of agitation speed, 4% of emulsifier concentration according to the observation with SEM and particle analyzer. The melting peak of microcapsules was shown to be 280$^{\circ}C$ The amount of released rosewood from microcapsules at 25$^{\circ}C$ was below 1 % and at 40% was below 3%. Therefore, polyurea microcapsules is capable of preserving rosewood oil for long self-life at normal temperature. Antimicrobial activity to dry cleaning and ironing cycle of wool fabric treated with microcapsules were maintained.

  • Three-dimensional(3D) virtual clothing simulation system may require the use of physical, mechanical, and configurational data in order to mimic the actual clothing with high degree of realism. Therefore the 3-dimensional scanning system based on optical methods was adopted to extract the 3-dimensional data of the fabric surface. In this study, the appearances of the 3-dimensionally transformed textile fabrics via several finishing procedures were investigated using a 3D scanning system. The wool gauze fabrics treated with the shrink-proof finishing and the felting process showed height changes up to 4.5mm. The 3-dimensional configuration may be objectively described by the use of mesh generation from the scanned output. The generated mesh information may further be utilized in the 3D virtual clothing simulation system for accurate description of the fashionable textile materials used in the simulation system.
