The composites of poly(l-lactide) (PLLA) and silica were prepared using a Haake melt mixer. In order to improve the interfacial adhesion between the two components silica was modified using three different silane coupling agents with different functional moieties. For the case that silica is treated with GPTS or MPTS, the molecular weight of PLLA are significantly reduced. This results in the lowering of the glass transition temperature ($T_g$) and melt viscosity of the composites. However, when the APTS-treated silica with amine functionality is added to PLLA, the storage modulus and melt viscosity of the composites are somewhat increased compared to neat PLLA. The rate of melt crystallization of PLLA is also increased as a result of surface treatment of silica.

The hydrophilic/hydrophobic nature of the cellulose could be tuned by introducing a polymer layer onto the surface using surface initiated polymerization techniques. Initiating groups for the polymerization could be immobilized by reacting 2-bromoisobutyrylbromide with the hydroxyl groups on cellulose. Thereafter, using atom transfer radical polymerization the modified cellulose was grafted with hydrophobic poly(methyl acrylate) (PMA), or with poly(N-isopropyl acrylamide) (PNIPAAm) which have been known for having lower critical solution temperature. We characterized the modified surface of cellulose using SEM-EDS and XPS, and FT-IR. The contact angles of the polymer grafted cellulose showed that the hydrophilic nature of cellulose surface was changed to hydrophobic after being grafted with PMA and to temperature dependent hydrophilic/hydrophobic with PNIPAAm.

Cotton fabrics were treated with glyoxal for a nonformaldehyde durable-press finish by a pad-dry-cure method. $MgCl_{2}/citric$ acid mixture or $Al_{2}(SO_{4})_{3}$ were used as a catalyst. The effects of additives such as sodium tetraborate decahydrate (STB), sodium peroxoborate tetrahydrate (SPB), and sodium chlorite (SC) were examined. The additives improved the whiteness and strength retention of the treated fabrics. SPB was superior to STB for the whiteness and strength retention. SC was better than either SPB or STB in the wrinkle recovery angles (WRA) and strength retention while the whiteness was similar to that of SPB or STB. SC was more effective for improving the whiteness and strength retention when it was used together with sodium phosphate monobasic.

The objective of this study was to investigate the dye absorption properties of chitosan/nano-silver composite fiber (CSF) and their blended knit fabrics (CSK) compare with cotton fiber (CMF) and their knit fabrics (CMK). The dye absorption of CSF and CSK showed relatively high level compared to that of the CMF and CMK, but K/S value of CMK was higher than that of CSK. In the case of CSF and CSK, most of dyes were exhausted within 20 minutes after completing the dyeing process regardless of dye reactive groups and affinities, and there were no significant decreases in the washing and rubbing fastness compared with CMK.

We designed a filter media which could collect of submicron size particles by applying electrostatic charge. To meet our proposed design, three different types of nano-scaled materials such as nonconductor ($SiO_2$), conductor ($Al_{2}O_{3}$), ferroelectric material ($BaTiO_3$) were incorporated into the melt-blown nonwovens made of micro fiber. Polypropylene melt-blown nonwovens, basis weights of $15\;g/m^2$ and $20\;g/m^2$, were prepared. The nano particles were diffused in the ethanol and then the electro sprayed on the nonwoven fabrics to be uniformly dispersed. The specimens containing nano particles were conditioned for three hours in the vacuum drying oven. To meet our purpose, the specimens were corona charged to develop the static electricity. The charging density and filtration efficiency of the filter media were investigated with various experimental conditions: such as types of additives and their concentrations. It was shown that the charging density and filtration efficiency were increased with increasing the basis weight of the samples. The filter media incorporated with ferroelectric particles showed the most desirable results compared with the other two additives.

Hanji woven fabrics are currently developed as a new multi-functional textile material due to their excellent properties of humidity control function, antibiotic, deodorant efficiency, and absorbency. In this study, Hanji union fabrics (silk $yarn{\times}Hanji$ tape yarn) were produced and their weavability, physical property, shrinkage, and color fastness were evaluated. Hanji paper and the tape yarns of $13g/m^2$ and 1.5-8.0mm were produced by a cylinder mould machine and a micro-slitter, respectively. From the weavability evaluation, a critical width of Hanji tape yarn as possible picking was found to be 2.0mm. As the width of tape yarn increased, the breaking stress and strain of the tape yam increased. Especially, after picking, the tensile property of Hanji tape yarn approached to the values of Hanji yarn. The shrinkage of dyed Hanji fabrics was 3.0% or less. On the evaluation of fastness to washing, the grade of Hanji union fabric showed good values and better value to the staining rather than color change. Also instead of washing, dry cleaning is desirable to the fabric. Hanji fabric was excellent in color fastness in grades 4-5 both to rubbing and perspiration, but was 3 grade to light resistance. To increase color fastness to light, plied yarn or union fabric with excellent light resistant yarn such as polyester may be applied.

The purpose of this study is to examine the satisfaction for the material and functional properties of climbing suit among the middle-aged hikers. The research consists of a survey which took place in the Kwanak Mountains. 200 hikers participated in this questionnaire of 33 questions that were developed in this study. Total satisfaction score was about 3.0 which showed middle. The lowest satisfaction were shown at price, size, abrasion durability, climbing safety, and easy washing in the order. Consumer age was found to be related negatively with the satisfaction for product maintenance, sewing quality, and the number of detail part of climbing suit. In size dissatisfaction, the part of the buttocks, the width of pants tube were the most dissatisfied and the width of sleeve, waist, shoulder, in the order. Lower clothes showed higher dissatisfaction in size than upper clothes. Not only its thermal comfort property, but also the size, abrasion durability, washing convenience and upper-wear stretch of climbing suit were found to be important for satisfying consumer's needs.

The advent of digital technology made the distinction between nations and languages, time and space, and even between the real world and the virtual no longer relevant or important. Innovation of digital technology in the field of Fashion is digital clothing. The purpose of this study is to conduct a theoretical investigation on how digital clothing could actually be applied in the clothing industry. The significance of this study lies in the facts that the various utilization plans presented herein further enhance the recognition of the necessity of research on digital clothing and that this research provides a solid foundation for further empirical study in pattern making. The fields in the clothing industry in which digital clothing will prove to be applicable are as follows; an innovative manufacture process which increases productivity through utilization of 3D clothing simulation, the activation of online stores, mass-customization production of clothing, SNS (social networking services), and etc. These newly emerging fields are of particular interest concerning the utilization of digital clothing technology. Research of digital clothing needs to be complemented and if that is achieved, digital clothing will bring innovation to all fields in the entire clothing industry; design, production, marketing, promotion, and so much more.

Recently many vectorizing methods have been developed and widely used to transform images into punctual data. However, conventional methods are used restrictively in vectorizing and needed for intervention by supervisors. To overcome the drawback, in this paper, we propose a vectorizing method based on image processing and linearization, and develop its application program. We show the effectiveness of the proposed method through experimental results on five test images.
