  • The tensile properties of polyester warp knitted fabrics of satin and reverse satin structure with various lengths of underlap were studied. In the range of low tension, the satin warp knitted fabric showed larger tensile energy and elongation in the direction of $0^\circ$ and larger tensile linearity, tensile resilience and initial modulus in $90^\circ$. Meanwhile, reverse satin one showed larger initial moduli in 0$^{\circ}$ and larger the others in $90^\circ$. In the range of high tension, the tendencies of both fabrics in $0^\circ$ direction were almost the same as those in all direction. As the under laps were shorter for both fabrics, tensile linearity, tensile energy and elongation increased, but tensile resilience decreased in all directions. However initial moduli were changed little.

  • This study was carried out to investigate the relationship between sound color and physical propertiessuiting fabrics. Rustling sounds of 23 suiting fabrics by sound generator developed for this study were recorded and analysed through FFT analysis. Three sound color factor(ΔL Δf. LPT) were obtained.Physical properties of specimens were measured by KES-FB. Level range(L) showed significant correlation with tensile resilience(RT) and thickness (T). Frequency difference(Δf) showed significant correlation with tensile linearity(LT), shear properties(G, 2HG, 2HG5), compressional energy(WC), and weight(W). Total sound pressure (LPT) showed significant correlation with elongation at maximum load (EM), tensile linearity(LY), and tesile energy(WT). By stepwise regression LPT was found to be explained by EM, MIU, RC, LT significantly.

  • The physical and functional properties of various woven fabrics with Hanji/cotton and Hanji/silk were examined. The tensile linearity, tensile resilience, bending rigidity, bending hysteresis and shearing stiffness increased with increasing Hanji yarn content. On the other hand, the compression linearity and coefficient of friction decreased with increasing Hanji yarn content. Grade 4-5 or 5 on the abrasion resistance and pilling test were obtained in six samples. The drape test showed that the flexibility of the samples was affected by the Hanji yarn content. Moreover, the shape of the samples showed anisotropy with increasing Hanji yarn content.

  • This study examined the abrasion and mechanical properties of poly(ethylene terephthalate) (PET) flameretardant fabrics used for window coverings. The tensile linearity, tensile resilience, bending rigidity, bending hysteresis, shearing stiffness, shearing hysteresis, compression energy, and surface roughness all increased with increasing fabric density and cover factor ratio. Five samples were subjected to more than 16,000 cycles for the abrasion resistance test and to grade 4 for the snagging test. The drape test showed that the flexibility of the samples was affected by fabric density and cover factor ratio.

  • This paper surveys the effect of rice straw ash solution to the physical properties of Sappan Wood dyeing fabrics. In the quantitative analysis of rice straw ash solution, the quantities of absorbed ingredients in fabrics were increased by bath pull treatment but the amount of absorption(K/S value) was increased by bath pH4.5 treatment. This is related to the metal ion. Among the metal ion, effect of Fe iou and Al ion were related. In case added extracted dye solution to mordants, the color dye solution became dark and increased reddish. The changes of mechanical properties of fabrics tensile resilience, bending rigidity(B), compressional resilience(RC) were increased. Generally mechanical properties were increased by rice straw ash solution treatment, specially bath pH9 treatment. Rice straw ash solution treatment of dyeing fabrics made the improvement in tensile strength and elongation and in the amount of absorption, dye ability, color fastness, mechanical properties, tensile strength, elongation.

  • This study investigated the effect of aftertreatments such as using the softener or starch on the mechanical properties of knitted fabrics. The mechanical properties of fabrics, hand value(HV) and total hand value(THV) were measured and calculated by the KES-F system. The main results are as follows: The values of tensile energy(WT), coefficient of friction(MIU) and geometrical roughness(SMD) were increased by softener but decreased by starch treatment. However, the values of tensile linearity(LT), bending(B, 2HB), thickness(T) and weight(W) were increased by starch but decreased by softener treatment. Tensile resilience(RT) was increased not only by softener but also by starch treatment. It showed that the levels of FUKURAMI, NUMERI and SOFUTOSA were increased by the treatment of softener and the levels of KOSHI and SHARI were increased by the treatment of starch. Total hand value(THV) was lower in fabric with starch treatment than fabric with none treatment.

  • Synthetic fabrics, such as nylon and polyester, were dyed with persimmon juice by using a padding mangle repeatedly. The mechanical properties of these synthetic fabrics were analyzed using the Kawabata evaluation system. The following findings were obtained from this investigation. As the number of repetitions of padding dyeing increased, the tensile energy per unit area and the tensile resilience of synthetic fabric remained almost unchanged, whereas the linearity of the load-extension curve of the synthetic fabrics increased. As the number of padding repetitions increased, the synthetic fabrics dyed with persimmon juice exhibited increases in thickness and weight. As the number of repetitions of padding treatment with persimmon juice increased, the values of stiffness, anti-drape stiffness, fullness, and softness also increased, whereas the flexibility with soft feeling, crispness, and scrooping sensation significantly decreased. The amount of coated persimmon juice on the surface of the fabrics increased after three repetitions of padding treatment with persimmon juice. Nylon and polyester fabrics were dyed evenly with persimmon juice treated using a padding mangle.

  • This study was performed for the development of antimicrobial finished nonwoven fabrics. Viscose rayon nonwoven fabrics were treated with commercial organic silicon quaternary ammonium salt using batch technique according to various treatment conditions. Antimicrobial activity was evaluated by shake flask method, and the reactivity of organic silicon were evaluated by measuring the absorbance using UV-visible spectrophotometer. Mechanical properties such as tensile, bending, shear, compression, and surface properties related to hand were measured by KES-F system. The results obtained from this study were as follows; 1. Antimicrobial activity was significantly affected by the treatment concentration and temperature, Excellent antimicrobial activity was obtained at 0.3% o.w.f. concentration and optimum treatment temperature 4$0^{\circ}C$. 2. Silicon content increased with increased treatment concentration. It increased up to 30 minutes of treatment time and then decreased. The reactivity of specimen treated at the temperature higher than 4$0^{\circ}C$ rather decreased. To obtain excellent antimicrobial activity, silicon content taken up by specimen should be more than 100 ppm. 3. Tensile resilience, bending hysteresis, compressional energy and mean deviation of frictional coefficient of the treated specimen were increased, and tensile linearity, tensile energy, bending rigidity, shear rigidity, shear hysteresis, frictional coefficient and geometrical roughness were decreased in comparison with those of untreated specimen.
