Most researches on the objective evaluation of fabric wrinkle have ignored that are really important parameters in subjective evaluation using standard replicas. This research has been conducted to find the important parameters in subjective evaluation. In this research, the number and depth of wrinkle were found to be the important parameters. The number of wrinkle was calculated from the ridge density and the distribution of distance between ridges. The depth of wrinkle was calculated from shade length distribution using image analysis. The results showed strong non-linear relationships with those of subjective evaluation.

To ensure the reproducibility of the dyeing of cotton knit by cold pad batch(CPB), the solubility, alkali stability and substantivity of multi functional type reactive dyes were tested. The color difference of the cotton knit CPB dyeing products between laboratory and dye house was measured. The results showed that the equipments, dyes and fabrics, all of them influenced the color differences of the final samples between the laboratory and dye house. These factors could not be controlled to reduce the color difference between the laboratory and dye house in the conventional computer color matching algorithm. A new color match prediction method based on the non-negative matrix factorization(NNMF) algorithm was introduced and the applicability was studied by comparing with the conventional color match prediction method based on the Newton-Lapson algorithm. The color match prediction method based on the NNMF showed more accurate recipe prediction results than the conventional color matching method for the CPB dyeing process of cotton knit fabric.

Two kinds of low-bandgap alternating copolymers composed of thiophene and benzothiadiazole were synthesized via the Stille coupling reaction. The effect of number of alkyl groups attached to oligothiophenes in the repeating unit of the copolymers on their optical, electrochemical, and photovoltaic properties was systematically investigated. One of the new polymers, poly(3,3"-dihexyl-2,2':5',2"-terthiophene-alt-2,1,3-benzothiadiazole) (P1), has better intermolecular packing than the other poly(3,3',3"-trihexyl-2,2':5',2"-terthiophene-alt-2,1,3-benzothiadiazole) (P2), and thus P1 is more beneficial for achieving high charge carrier mobility. P1-based device shows the power conversion efficiency as high as 2.19% when blended with [6,6]-phenyl-
-butyric acid methyl ester after thermal treatment at
for 30 min.

Compared to the conventional viscose rayon process, Lyocell process using NMMO as a solvent provides a naturally-friendly, less toxic, relatively simple method for producing regenerated cellulose fiber with excellent properties. Existing wood pulp based Lyocell, however, shows some disadvantages such as forest destruction. So, in this study, a novel regenerated cellulose fiber, cotton linter based Lyocell, was prepared by dry jet-wet spinning with a lab scale equipment changing concentration of cellulose/NMMO solution, take-up speed, etc, which are strongly related with fiber properties and its properties were compared with wood pulp based Lyocell fiber. The tenacity and strain at break of the resultant fibers were correlated with the intrinsic fiber properties such as birefringence, crystallinity, and crystalline orientation index.

A magnetorheological fluid(MR fluid) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. And, Shape-memory polyurethane(SMPU) is a kind of polymeric smart materials that have the ability to return from a deformed state to their original shape induced by an external stimulus, such as temperature change. In this study, the multi-functional fiber webs showing magnetorheological(MR) property under magnetic field and shape memory(SM) effect by heat were prepared by coaxial electrospinning process. The fibers were designed to consist of two part; core part, SMPU+MRF and sheath part, SMPU. Consequently, we found that ca. 10 wt% MRF+15 wt% SMPU solution is most suitable for core part dope solution, and 17 wt% SMPU solution is most suitable for sheath part dope solution. Through scanning electron microscope(SEM) and transmission electron microscope(TEM), we observed stable core/sheath structure in the fiber of the electrospun web. From the dynamic mechanical analyzer(DMA) result to investigate the shape recovery ability of the fibe webs by heat, we discovered reasonable shape recovery property from the electrospun fiber web. Also, they showed MR effect under magnetic field through universal testing machine(UTM) test.

In this study, we investigated PLGA/graphene composite scaffold prepared by electrospinning method for its possible application in biomedical fields. Mixture of 16 wt% PLGA and 0.1~1.0 wt% well-dispersed graphene dissolved in 1,2-dichloroethane co-solvent was used as a dope solution for fabricating a mat type of electrospun PLGA/graphene composite scaffold. The morphological structure of the composite scaffold was examined by FE-SEM, indicating that monolayered graphene was well hybridized inside the PLGA microfiber (ca. 900~1000 nm fiber size). Indirect evidence of graphene inclusion in the composite scaffold was confirmed by X-ray diffraction analysis and thermal gravimetric analysis quantitatively. As a result of tensile test, the PLGA/graphene composite scaffold had an excellent tensile strength (2~2.5 times higher), breaking strain (2.5~3.5 times higher) and Young's modulus (1.2~2.4 times higher) compared to electrospun PLGA scaffold. Cytotoxicity and cell proliferation of the composite scaffold were also performed by MTT assay using MC3T3-E1 and NIH3T3 cell, showing that graphene-containing PLGA scaffold has no cytotoxicity and even much better cell adhesion and proliferation ability. Therefore, it is concluded that the electrospun PLGA/graphene composite scaffold can be potentially used in biomedical applications for tissue engineering, due to excellent mechanical properties as well as high cell compatibility.

New techniques of ultrasonic welding and seam sealing have been developed instead of conventional sewing method to improve the performance of seam part of outdoor. The effects of the welding speed, seam sealing speed and washing cycle on the physical properties of seamed fabrics were investigated in this paper. The tenacity of seamed fabrics by welding after seam sealing process is about 70% of the tenacity of the seamed fabrics by conventional sewing after seam sealing process. The increase in speed of welding and seam sealing causes decrease in tenacity of seamed fabrics. The hydrostatic resistance and water vapor transport phenomena of welded fabrics are also discussed. The washing process affects the properties of seamed fabrics very slightly.

Melting temperature of the poly(ether-ester) copolymers are generally around
and are suitable for moisture barrier in active sportswear, but higher melting temperatures are required for them to be used in personal protective clothing. In an attempt to obtain higher melting poly(ether-ester) copolymers, copolymerization of bishydroxybutyl naphthalate and poly(ethylene glycol)-b-poly(propylene glycol)-b-poly(ethylene glycol) tri-block copolymers (EPE) was carried out to obtain poly(butylene 2,6-naphthalate)/EPE copolymers with poly(butylene 2,6-naphthalate) (PBN) as hard segments and EPE as soft segments. PBN/EPE copolymers containing different amounts of EPE (0, 5, 10, 20 and 30 wt%) of different molecular weights (1100, 2000, 2800 and 5800) were prepared. Composition analysis, solution viscosity and density measurements were made. The composition of copolymers determined from
-NMR spectra were similar to feed composition.

In most conventional applications, geosynthetics are exposed to highest mechanical stress during installation. A series of laboratory simulation test for installation damage of geomembrane (GM) was carried out at different loading cycles on HDPE GMs where ISO 10722:2007 was used as a guide. The tensile properties of the samples were tested. The result of the test is reported and it has been found that number of loading cycle has irregular influence on installation damage. It is known that the service life of a GM depends on the exposure conditions, which in a landfill may involve adverse chemical exposure, elevated operating temperatures, and potentially large physical stresses. New equipment was developed and the installation damaged GM samples were exposed to pH solutions under different stress at elevated temperature for hours. Tensile tests was performed to get the residual strength and analyzed. It has been noticed that as the applied stress on GM samples increases, residual tensile strength decreases and they showed higher tolerance to acidic condition than alkali condition.

Surface treated bottom ash was utilized as a filler to prepare plastic composites. Bottom ash surface was modified with octyltriethylammonium bromide (OTAB) or hexyltriethylammonium bromide (HTAB) by ion exchange procedure in methanol solution. Surface-modified bottom ash was then melt-compounded with HDPE to investigate its compatibility with the matrix material. The mechanical properties such as tensile, compressive, and impact strength, in addition to morphologies, were analyzed to determine the advantage of surface treatment compared to using bottom ash without treatment. Tensile strength and compressive strength increased with increasing bottom ash content.

Spin draw yarns (SDY) of polypropylene/poly(L-lactic acid) (PP/PLA) blends with various PLA contents were prepared using a commercial pilot spinning apparatus. Melt-quenched PP/PLA blend films were also prepared by melt-pressed the PP/PLA SDY fibers or PP/PLA blend chips at
and quenched in ice water. Thermal and mechanical properties of the PP/PLA blend fibers and films were analyzed by using a differential scanning calorimeter (DSC), a scanning electronic microscope (SEM), and a universal testing machine (UTM). Results showed that the melting temperature of the PP in the blends was unaffected by PLA blending and that PP and PLA crystallized independently. Although the melt-crystallization temperature increased slightly with increasing the PLA content in PP/PLA blends, the amount of PP crystal was not affected. PLA existed as beads in PP matrix, indicating that PP/PLA blends are immiscible. Tensile tenacity decreased and extension at break increased with increasing PLA content in PP/PLA SDY fibers.
