  • In order to investigate the changes in mechanical properties of sanitary nonwoven fabrics actually used as a top sheet, the fabric was treated with a mixture of chitosan and nanosilver colloidal solution in accordance with the prescribed ratio. The former is a natural polymer with excellent biocompatibility and the latter can give an additional performance while compensating the weaknesses of chitosan of deteriorating adherence efficiency. It was shown that the bending and shearing characteristics of the chitosan/nanosilver treated fabrics decreased, which helped to make it softer, smoother and more flexible. The shape stability and drapability of the treated fabrics improved. As KES-FB system evaluation showed that Koshi was deduced, and both Numeri and Fukurami were increased. Thereby, the chitosan/nanosilver treated fabrics were smoother to provide elasticity. In the change of hand value compared to chitosan only treatment, a better THV was shown in the fabrics treated with chitosan/nanosilver mixed solution than the fabric treated with chitosan alone.

  • N-methylmorpholine-N-oxide(NMMO) is recently hewn as a solvent dissolving cellulose to produce a new regenerated cellulosic fiber, lyocell. In this study, four kinds of cellulosic fibers (lyocell, regular cotton, treated cotton with 50% and 75% NMMO aqueous solution) was examined and compared in terms of mechanical properties and dyeability. The swelling of cotton treated with NMMO aqueous solution is higher than that of cotton treated with water. In dyeing rate, the cotton treated with NMMO was faster than regular cotton. NMMO treatment decreased the crystallinity of cotton fabrics and improved their softness and smoothness.

  • This study surveys the mechanical properties such as tensile and compressional properties to the weight reduction rate of PET fabrics with various weft linear densities, weft t.p.m. and desities. 18 kinds of plain and 12 kinds of satin weave fabrics were woven and processed with variation of weight reduction rate(0%, 12%, 25% and 30%) in dyeing and finishing processes. Tensile work, resilience and compressional work and resilience of these finished fabrics treated with different weight reduction rates were measured by KES-FB System and discussed with various wok linear densities, weft t.p.m., densities, and weight reduction rates.

  • This study was carried out to evaluate the distribution of mechanical and thermal properties of 14 sorts of tencel fabrics. Three kinds of cellulosic fabrics such as cotton 100%, cotton/tencel 50/50% and rayon 100% were used to compare with tencel fabrics. Furthermore, for the comparison of thermal properties, these fabrics were repeatedly washed 1, 3, 5, 10, 15 and 20 times respectively. The mechanical properties were measured by the KES-FB system and Thereto Labo II type was employed to measure the thermal properties of warmth retaining and contact warm/cool feeling($q_{max}$). The experimental results were analysed statistically to relate the mechanical and thermal properties. Tencel showed sufficient ability to recover from bending deformation and drapability comparing with other cellulosic fabrics and had a silhouette which goes along with the body.

  • The purpose of this study was to quantify the hands of fabrics for the Korean folk clothes using both a KES-FB and an artificial neural network. In order to select the proper input parameters, we calculated the correlation using step-wise regression between mechanical properties and the hand value of fabrics. For the classification, the primary hand values and total hand value, five neural networks with three-layered structure were constructed using the error back propagation algorithm and, in order to reduce errors and to speed up learning, the momentum method was selected. From the analysis of the primary and total hands using a self-constructed artificial intelligence system, the error rates of sleekness, stiffness, silkiness, and roughness compared with the judgement of expert panels were found to be 3.3%, 3.3%, 1.6%, and 4.9%, respectively, while that of the total hand was 9.83%.

  • The primary objective of this study was to empirically explore the mechanical properties of marketing Korean fabrics by using KES-FB system and estimate the sewability of Korean clothes by the mechanical properties. From the empirical research, it was found that Korean fabrics for spring and summer has been transformed easier and less flexible by shearing Korean fabrics for autumn and winter. Also, it was found that there is a significant difference in the hand value as tensile, surface and compression. It was found that Korean fabrics for spring and summer has a stiffness and elastic properties of matter and Korean fabrics for autumn and winter has a bulky and abundant elasticity. Finally, it was found that Korean fabrics for autumn and summer in the joint of account of the mechanical properties. Also, the difficulties of process has been expected by sewability like seam-pucker, over feed, sewing and steam-press.

  • Fabric hand was assessed for 14 women's spring-fall dress fabrics based on the subjective hand evaluation scale developed in the part 1 of this study. The effects of fabric type, seam and dress style on the subjective hand evaluation of 470 Korean consumers (205 textile experts and 265 non-experts) were investigated. Mechanical properties obtained from KES-FB system were compared with the each dimension of subjective hand expression. The type of fiber and construction were considered to be important factors in affecting hand assessment of Korean consumers, however, the presence and type of seam were not considered to be important. There were certain characteristics of subjective hand attributes for each dress style. Surface properties of fabrics, even though it is not strictly mechanical properties, appeared to be the most effective dimension in the developement of new products which appeal to Korean conssumers.

  • Cotton fabrics were finished with mixture of BTCA and silicone by pad-dry-cure process to achieve better mechanical properties than those of finished with BTCA alone. The changes of mechanical properties o( finished cotton fabrics were measured with by the KES-FB System and the hand values were calculated from the data of mechanical properties. With the durable press finish with BTCA tensile, bending, shear and compression properties increased. In hand values, Stiffness Crispness and Anti-Drape Stiffness increased, and Fullness & Softness decreased. Whereas silicone treatment reduced bending and shear properties and improved tensile and compressional resilience. Thus, Stiffness Crispness and Anti-Drape Stiffness decreased, and Fullness & Softness increased. These results indicated that BTCA treatment restricts fiber/yarn mobility in the fabric structure due to crosslinking, but silicone treatment reduces inter-fiber and inter-yarn frictional forces. Therefore, finish with mixture of BTCA and silicone provided cotton fabrics with a lower Stiffness, Crispness and Anti-Drape Stiffness and a higher Fullness & Softnesss than finish with BTCA alone.

  • This study surveys the warp and weft tension differences between projectile and air-jet looms and analyses the mechanical properties of worsted fabrics for garment with relation of these loom characteristics using KES-FB system. The paper is divided by two parts. In the 1st paper, the worsted fabric is woven as 5 harness satin weave using 1/40 Nm sirofil worsted warp yarn and 1/30 Nm worsted weft yarn by projectile(Sulzer) and air-jet looms(Picanol PAT and OMNI), respectively. The weavability is also analysed by measuring warp tension variation according to the warp position and weft tension of 3 kinds of looms. The relationship between shed amount and the warp tension is surveyed, and the relationship between end breaks and warp and weft tensions is also discussed.
