  • It is difficult to dye nylon/viscose rayon mixture fabrics by one-bath one-step dyeing method, because acid dyes and reactive dyes require acidic dyebath for adsorption and alkaline dyebath for fixation respectively. In order to overcome the disadvantage of the conventional two bath two step dyeing method of nylon/viscose rayon mixture fabric, it was pretreated with cationizing agent containing chlorohydrine group in aqueous solution of sodium hydroxide. The pretreated nylon/viscose rayon mixture fabrics produced cationized fabrics that could be dyed with acid dyes and reactive dyes under neutral condition. This study was carried out to investigate dyeing possibilities, surface reflectance spectra and color characteristics of cationized nylon/viscose rayon mixture fabrics with acid dyes and reactive dyes in a non-electrolytic and neutral dyebath by one bath one step dyeing method.

  • Super-hydrophobic surface, with a water contact angle greater than $150^{\circ}$, has a self cleaning effect termed 'lotus effect'. We introduced super-hydrophobicity onto aramid/rayon mixture fabric with dual-scale structure by assembling silica nano-sol. Mixture fabric was treated with silica nano-sol, fluoric polymer using various parameters such as particle size, concentration. Silica nano-sol size were measured using particle size analyzer. Morphological changes by particle size were observed using field emission scanning electron microscopy(FE-SEM), contact angle measurement equipment. The contact angle of water was about $134.0^{\circ}$, $137.0^{\circ}$, $143.0^{\circ}$, $139.5^{\circ}$ and $139.0^{\circ}$ for mixture fabric coated with 100.2nm, 313.7nm, 558.2nm, 628.5nm and 965.4nm silica nano-sol, compared with about $120.0^{\circ}$ for mixture fabric coated with fluoric polymer. When we mixed particle sizes of 100.2nm and 558.2nm by 7:3 volume ratio, the contact angle of water was about $146.2^{\circ}$. And we mixed particle sizes of 313.7nm and 558.2nm by 7:3 volume ratio, the contact angle of water was about $141.8^{\circ}$. Also we mixed particle sizes of 558.2nm and 965.4nm by 7:3 volume ratio, the best super-hydrophobicity was obtained. In this paper, we fabricated the water-repellent surfaces with various surface structures by using four types of silica nano-sol, and we found that the dual-scale structure was very important for the super-hydrophobicity.

  • In this paper, chitosan was suggested for using as a replacement for sodium alginate in the pretreatment print paste for digital ink-jet printing for cotton fabric. Pretreatment print pastes prepared from the mixture of chitosan and acetic acid with the appropriate viscosity gave satisfactory prints on the cotton fabric. Chitosan-treated cotton fabrics were digitally ink-jet printed with four different colors and the color fastness rating of the printed fabrics was satisfactory. Experimental results revealed the possibility of pre-treating the cotton with chitosan to replace the sodium alginate normally present in the pretreatment print paste recipe.

  • 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.

  • Different people buy the same or similar products for different reasons. Benefit segmentation attempts to understand these differences by grouping together people who assign a similar level of importance to the same attributes. We focused on identifying market segments for knit fabrics by comparing the relative attribute preference for knit fabrics according to segmented clusters, and testing to establish if there were significant differences between the preferences of clusters. Three consumer segments emerged, and there were three clusters with different ideal knit profiles: a preferred wool group, a preferred acrylic group, and a preferred long stitch length group. The preferred wool group and the preferred acrylic group rated the mixture ratio as the main attribute that determined their preference, followed by the stitch length. The preferred long stitch length group considered stitch length as being the most important attribute, followed by the mixture ratio. The difference in the preferences for the mixture ratio and stitch length of knit fabrics was the highest between the three clusters, The preferred wool group preferred a knit fabric that has a greater wool mixture ratio and a short stitch length, and the preferred acrylic group and long stitch length group preferred a knit fabric that had a higher acrylic mixture ratio and a short stitch length.

  • 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

  • The color mixture, obtained from Indigo and Japanese pagoda tree, was applied to cellulose fibers such as cotton, linen and rayon to diversify color gamut of natural dyes. The color mixture was tried with two different methods. The first process was that cellulose fibers were dyed with $5{\sim}25%$ owf Japanese pagoda tree solution, and then dyed 1 to 4 times with Indigo. The second process was dyeing 1 to 7 times with Indigo, followed by dyeing with $5{\sim}25%$ owf Japanese pagoda tree solution. K/S value of the dyed fibers with one colorant and color mixture increased in the order of linen, cotton, rayon. It was also found that the first process could give higher K/S values than the second process.

  • Cotton fabrics were finished with mixture of BTCA(1,2,3,4,-butanetetracarboxylic acid) and polyalkyleneoxide-modified amino-functional silicone by pad-dry-cure process to achieve better DP performance with a higher retention of physical properties as compared to those of finished with BTCA alone. The results indicated that BTCA improved the wrinkle recovery but reduced significantly the tensile and tear strength of the treated fabrics. Whereas silicone imparted a lower wrinkle recovery, a lower loss of tensile strength than BTCA, in addition improved considerably the tear strength owing to reduction in inter-fiber and/or inter-yarn frictional forces. The concentration and curing temperature needed to enhance physical properties were as follows; for BTCA treatments 6%, at 18$0^{\circ}C$, for silicone treatments 1% at 14$0^{\circ}C$. This optimum concentration of silicone was observed by using the mixture of BTCA and silicone. The wrinkle recovery and DP rating of cotton fabrics treated with mixture of 4% BTCA and 1% silicone at a curing temperature of 17$0^{\circ}C$ was similar to those of treated with 6% BTCA at a curing temperature of 18$0^{\circ}C$, and other performance properties observed were; an increase in tensile strength, extension, toughness, abrasion resistance and moisture regain due to the reduction of BTCA concentration and curing temperature, futhermore an improvement in bending and surface properties due to the lubricating effect of silicone. On the other hand 1% aqueous silicone solution showed the lowest surface tension. Such nonionic surface activity resulted in a more uniform and rapid deposition of BTCA on the fiber or fabric.

  • This study explicates some properties of the fabrics used in the 16th century by examining and analyzing the 90 pieces of fabric excavated from the graves of Mr. Ryu of Jinju and his wife Mrs. Park of Euiin. The fabrics were classified into silk tabby(紬), thin silk tabby, satin damask(段), complex gauze(羅), mixture fabric with silk and cotton(絲棉交織), cotton(棉布) etc. Compared to other contemporary fabrics excavated previously, the fabrics unearthed from the couple's graves presented very naive feelings. Patterned satin damask occupied a small portion. In the case of plain fabric, little filament silk tabby(絹) or thin filament silk tabby(細紬) was unearthed. Important data on the history of Korean costumes are provided by the noteworthy, first-ever excavation of a small cap made of complex gauze(羅) and the tiger-leopard embroidered patches called hyoongbae(胸背), which were worn on the front and back of official robes made of tabby with supplementary gold thread(金線). Only 3 pattern types could be clearly identified in form, cloud pattern, lotus and vine pattern(蓮花蔓草), and small flower and treasures pattern(七寶細花). These three patterns are very similar to those of other 16th century fabrics unearthed previously in terms of the form and arrangement of patterns.
