  • In this study, we attempted to expect the mechanical characteristics of the wool fabrics by knowing the yarns. Moreover, we believe that we could apply these results to fabric design. We investigated the relationship between the mechanical characteristics of yarns and fabrics. As results, we have found that bending rigidity, bending hysteresis, compressional energy and compressional linearity between yarns and fabrics had correlated more than r=0.5. Also, the correlation between regression and experimental values is r=0.5 in stiffness while it is r=0.67 in fullness. And regression values were larger than experimental ones in stiffness, but were not in fullness. The correlation between regressional and experimental values had 0.63 in THV. According to the study, it is possible to apply it to fabric design when our predicting the primary hand and the total hand values of the fabrics from the mechanical characteristics of the yarns.

  • The purpose of this study is to suggest a guidance to select proper muslin through investigating fabric characteristics. The structural and physical properties of muslin and top fabric samples were tested by KES-FB system and other testers. And in order to examine the relation between fabric characteristics and the shape of garments, wearing tests were done with jackets made of those samples. As a result, bending rigidity(B), bending hysteresis(2HB), shear stiffness(G), shear hysteresis at=0.5(2HG), shear hysteresis at=5(2HG5), stiffness, cloth count/5cm, weight, thickness were extracted as the key factors affecting the appearance of garments. To have similar appearance, all of these should be counted. After standardizing, we calculate the variance between top cloth and muslin. And from this we could get the range that the proper muslin should be included. The ranges were as follows: Bending rigidity(B): within 0.024g.$\textrm{cm}^2$/cm(0.3$\sigma$); Shear stiffness(G): within 2.21g/cm.degree(1.3$\sigma$) Weight: within 9.33mg/$\textrm{cm}^2$(18$\sigma$); Thickness: within 0.20mm(1.8$\sigma$)

  • The purpose of this study is to investigate the softening effect of cellulase-treated cotton fabric and the damage on the fabric which is accompanied by the treatemnt. Cotton fabric is treated with cellulase under various concentrations and time, and the weight loss, hand values (by KES), surface characteristics, moisture regain, tensile strength, copper number and intrinsic viscosity of the treated samples and untreated samples have been compared. The results are as follows: 1. The weight loss of cotton fabric increased as the concentration of cellulase and the treating time increased. 2. The enzyme treatment had little effect on the stiffness of the treated samples but anti- drape stiffness decreased for the treated samples. Fullness and softness of the treated samples increased and crispness decreased with the lowest level reaching after two hours of the treatment for all concentrations. Scrooping feeling of the treated samples increased and flexibility with soft feeling increased as the treating time and the concentration of cellulase increased. 3. Moisture regain of the samples decreased as the treating time and the concentration of the enzyme increased and the treated fabric showed cracks on the fiber surface, and much surface fibers on the fabric have been removed after the treatment. 4. Tensile strength of the samples decreased as the treating time and as the concentration of cellulase increased, and the copper number increased while the intrinsic viscosity decreased as the treating time increased, but cellulase concentration had a little effect.

  • The effect of additives in final rinse water during laundering on soiling, soil removal and some properties of fabrics has been studied with various fabrics. The additives examined were fabric softener (Sta-Puf), cationic surfactant (Apole PS), sizing materials such as CMC, PYA, cornstarch and mixture of CMC and cationic surfactant. The results obtained may be summerized as follows. L Addition of additives except PVA in final rinse water generally reduce the deposition of carbon-$CCl_4$ soil and it seems to be rather independant of the concentration of additives. The effect of additives on soil resistant is found to increase in the following order. cotton; Apole

  • Because the compressive properties such as compressive stiffness and compressive maximum strength of the fabric composite materials are essential to analyse the drape behaviour and estimate the quality of the final products, compressive tests of fabric composites with different stacking sequences were performed. Appropriate shape and dimensions for the compressive test specimens were prepared and several specimens with different conditions were tested and compared with each other.

  • Synthetic fiber materials were developed due the desire of consumers for high-quality, high-performance and comfort. A high functionality of synthetic fiber can be obtained through surface treatment that can improve hydrophilic properties, color depth after dyeing and adhesion properties. These advantages create added-value. Hydrophobic properties are an important feature to create added-value (such as hydrophilic properties). One side processing is a method of imparting to contrary function on the front and rear side. In this study, fluorine-coated Nylon/PU blended fabric was treated on only one side with a low-temperature plasma treatment; subsequently, the contact angles decreased by increasing the time and intensity of the plasma treatment. The contact angle of the untreated surface and the treated surface was different. It a showed a difference in the properties of both surfaces. Tensile strength and stiffness decreased by increasing the time and intensity of the plasma treatment. However, plasma treatment did not significantly change the tensile strength and stiffness on both surfaces of the fabric. SEM photographs showed the surface of fluorine-coated fabric and the etching surface by using plasma treatment on the fabric. Plasma treatment was confirmed not to affect the physical properties of the fabric.

  • The purpose of this study is to examine the difference of judge's gender and age groups in preference of S/S men's suit fabrics, and to analyze the relationship between the preference and the texture by gender and age group. For this study, 60 types of S/S men's suit fabrics were used with variously-composed fibers, such as wool, wool-blended, and PET, thickness, and weight. To evaluate the texture and the preference subjectively, nine ranks' semantic differential scale questions of 22 texture adjectives and preference of 4 apparel items were developed, Through the factor analysis, texture adjectives were classified into 7 categories: "stiffness," "elasticity," "bulkiness," "coolness," "smoothness," and "drapability." Depending on gender and age groups of judges, statistically significant differences on texture factors and the preference were observed. Especially, men under 30 years of age showed a higher grade of stiffness and a lower preference on pants than other groups. The relationship between the texture and the preference was different by gender and age group: Women evaluated a preference of men's suit fabrics in relation to stiffness and smoothness, whereas men did so in relation to stiffness, smoothness, coolness, and drapability. A young age group put more importance on drapability for preference of men's suit fabric.

  • As important factors determining human sensorial comfort, liquid moisture management and surface properties of heat resistant workwear materials were examined. To figure out liquid moisture management properties of the test materials, absorption capacity, rate of absorption, and evaporation properties were assessed. A modified GATS(Gravimetric Absorbency Testing System) was used to measure the liquid moisture accumulation associated with the wicking of liquid moisture from sweating skin. The GATS procedure measures demand wettability of materials to take up liquid in a direction perpendicular to the fabric surface and it was modified to incorporate a special test cell and cover to assess absorption behavior in the presence of evaporation. Fabric stiffness, smoothness, number and the length of surface fibers, and an estimate of the contact area between the skin and fabric surface were measured to characterize the mechanical and surface properties of the test materials. Also an estimate of the force with which a fabric clings to moist skin was made using as wet-cling index.

  • There are two standards for evaluation of fabric aesthetics, the feeling of fabric and the fabric sense of sight. Its drapalility with lustre is one of factors to decide the fabric sense of sight. This study was carried out to investigate the drape property property of fabrics. The fabric characteristics and the physisical properties of fabrics were tested. And the effect of the laundering on the drape properties was examined. RESULTS : 1. The drape coefficients of sampled fabrics were increasd as the thickness of fabrics were increased, excluding the fabric consisting of 60% polyester$\times$40% wool. 2. The drape coefficient of sampled fabrics were decreased as the cover faders of fabrics were increased, excluding the summer clothes and the fabrics of 100% wool. 3. The drape coefficients of fabrics other than sumer clothes were increased as the weight of fabrics were in creased. 4. Positive correlation was observed between the stiffness and the drape coefficient. 5. Negative correlation was observed between the fabric shrinkage and the drape coefficient. 6. The drape coefficient was decreased to a certain limit by laundering.But as the laundering was repeated up to certain number, the drape coefficient and the node number, a significant correlation was observed between the drape coefficient and the node shape.
