ABSTRACT
In this study, various nylon fabrics were investigated to measure the physical properties of the actual fabric using Kawabata systems and CLO fabric kits, and the correlation between the physical and drape properties of the fabric was statistically analyzed. Subsequently, the CLO fabric kit results were used as basic data for the CLO three-dimensional (3D) virtual clothing program, and the drapeability of the virtual fabrics was measured. The factors with the most significant effect on the drape properties were analyzed by comparing the drape measurement of the real fabrics through the variable measurement of various fabrics and correlation analysis with the drape properties, and attempts were made to reduce the difference between real fabrics and their virtual implementations. The correlation analysis results revealed that both the Kawabata system and CLO fabric kit results indicated that the bending and shear properties exhibited the highest correlation with the drape ratio. In addition, the comparison of the real and virtual fabric images revealed that they exhibited a similar morphology. Furthermore, the results confirmed that the difference between the real and virtual fabrics could be reduced as much as possible when the values measured using the Kawabata system and CLO fabric kit were converted into a database. Subsequently, the differences between virtual fabrics with various thicknesses were confirmed through CLO 3D simulation. The findings of this study are expected to be used as basic data for building fabric database.
ABSTRACT
A new reactive urethane-silicone softener was developed to provide a soft touch to cotton knit fabrics with improved durability to washing and dimensional stability. The reactive urethane-silicone softener consisted of an amino silicone softener and a blocked isocyanate, which can crosslink and react with cellulose surfaces. The activated isocyanate from the blocked isocyanate reacted with the amino silicone softener by heat treatment at 150 °C for 30 min. The mechanical properties of the cotton knit fabrics treated with the urethane-silicone softener were evaluated using a Kawabata Evaluation System-Fabrics (KES-FB) system. The cotton knit fabrics treated with the urethane-silicone softener showed excellent elasticity, flexibility and shear recovery as well as excellent recovery against bending deformation, and soft and smooth surface characteristics with a small coefficient of friction that were maintained even after washing 20 times.
