New types of fibers or yarns are often in the development of high-quality textile products. However, their processability is difficult to estimate or evaluate and is detemlined subjectively by experienced engineers or technicians. Therefore a measurement was developed to define more objectively the processability of yarns, especially the weavability of warp yarns. Warp yarn tensions were measured on a test rig to collect information on weavability. Hair occurrence, entanglement of warp yarns, yarn breakages, and warp tension relaxation were measured and combined with weighting factors to establish a weavability index of the warp yarns. The weighting coefficients were chosen according to the experience of users. Weavability index has the potential to allow the prediction of a yarn's performance it is woven. An example use of the index is discussed.

Multi-layered, prepreg or preform textile structures are often used in industrial components to achieve specific mechanical properties. Therefore a beam scanning method was developed to measure the internal structures of multi-layered preforms in a nondestructive way. The measurement system employed a low-energy X-ray beam and an X-ray detector. Specific software programs were also developed for image data processing. Trial measurements of textile specimens prepared from compound yams demonstrated the system's ability to image internal structures by detecting the layers' folded states. The method can feasibly be used for measuring the internal states of specimens with stacked textile structures.

Polycarbonate (PC)/mineral silica composites were prepared by melt-mixing to improve PC's surface characteristics. The silica's surface was modified using a silane coupling agent with amine functional moiety prior to blending. The effects of silica on the PC's morphology, dynamic mechanical properties, molecular weight, and pencil hardness were investigated. Although SEM showed that silane treatment promoted interfacial adhesion between the PC and the silica, the storage modulus of the PC/silica composites increases with increasing silica content irrespective of silane treatment. Silica addition decreased the molecular weight (MW), and thus the melt viscosity of PC in the composites. The reduction was slightly greater at higher silica contents and when silane-treated silica was added. Despite the detrimental effects of silica on the MW, the pencil hardness of the PC increased to F grade when silane-treated silica of 40 phr was added possibly due to the increased modulus and interfacial adhesion.

The effects of drawing on the structure and physical properties of nylon 6-ran-nylon 4 copolymer filaments were assessed by uniaxially drawing filaments at various ratios at 90 DC and measuring their crystal structure, birefringence, moisture regain, dynamic viscoelasticity, thermal behavior, and tensile properties. X-ray diffraction curves showed sharper peaks with increasing draw ratio. Birefringence and heats of fusion (
) increased with increasing draw ratio, while a slight decrease in moisture regain was observed. The intensity of the
peak decreased and its position shifted towards higher temperatures with increasing draw ratio. Breaking strength increased and breaking elongation decreased with increasing draw ratio.

Textile-based sensors have many advantages when applied to body assessment. They have greater comfort than IT sensors and their use has substantially increased recently. Fiber-based sensors have various factors affecting their detecting ability such as pressure, voltage, current, and capacitance. Fiber-based sensor fabrics with sheath-core type conductive yarns were produced and relationships between capacitance changes and applied loads were investigated. The physical and electrical properties of the fiber-based sensor fabrics were investigated under various dyeing and finishing conditions. Dyeing and finishing conditions were optimized with respect to electrical properties using a signal detecting circuit.

Textile Science and Engineering, volume 48, issue 3, 2011, Pages 166~171
Geogrids and geotextiles' shear behaviors were evaluated after installation damage testing. Frictional coefficients of resistance to direct sliding (
) were estimated by theoretical shear analysis. The shear strength of the damaged geogrid decreased under a high normal stress of 150 kPa; that of the geotextile decreased with increasing normal stress. fds values were found to be lowered by installation damage, through comparison of
values calculated by direct theoretical shear analysis before and after installation damage.

Rosin pre-treatment was studied to improve the quality of digital textile printing. Silk and cotton media were tested with reactive and pigment inks. The K/S value of cotton printed with reactive ink was decreased by rosin treatment. The K/S values of cotton and silk printed with pigment inks were increased by rosin treatment, making rosin-treated samples more effective in obtaining dark color during pigment ink printing. MIU, MMD, and SMD values, closely related to surface roughness and printing quality, were lowered by rosin treatment. B and 2HB values increased with increasing concentration of rosin used during treatment. Line printing tests showed decreased line blurriness of rosin-treated silk and a sharper line was printing.

Multi-walled carbon nanotubes (MWNTs) were functionalized with chitosan using Cu-catalyzed Huisgen [3+2] cycloaddition click chemistry. Azide moiety-chitosan was prepared by synthesizing azide-moiety epichlorohydrin and its subsequent reaction with chitosan. Alkyne-functionalized MWNTs were separately prepared by the diazotization reaction of MWNTs with p-amino propargyl ether. Covalent functionalization of the MWNTs was accomplished through click coupling between the alkyne-derived MWNTs and the azide moiety-chitosan. The reaction was confirmed by FT-IR, Raman, SEM, and TEM measurements. Functionalized chitosan was observed by TEM on the surfaces of the MWNTs after click coupling. Electrical heating with a maximum of
occurred when a voltage of 60 V was applied to the MWNT/chitosan composites, further demonstrating the chitosan functionalization of the MWNTs.

Blended yarns comprising CDP and Tencel (TA) were produced for fabrics with improved color intensity. Their tensile force and extension and bending properties were investigated to evaluate their ease of handling during use. Their surface properties were also assessed by SEM and evaluating hairiness. Tensile force and extension decreased with increasing TA content due to slippage between CDP and TA. Bending strength was directly proportional to TA content.

Highly hydrophilic, hydrolyzed polyacrylonitrile (PAN) particles can be used as moisture-absorbing, heat release materials for textiles. However, its high hydrophilicity makes PAN soluble in water; therefore it should be cross-linked prior to hydrolysis. Variously sized PAN nanoparticles were synthesized by the dispersion/emulsion polymerization of acrylonitrile (AN) monomer using sodium dodecyl sulfate (SDS) and potassium persulfate as an emulsifier and an initiator, respectively. The resulting nanoparticles' sizes, shapes, and size distributions were studied. Increasing concentrations of SDS and AN led to larger particles. PAN nanoparticles with an average size of ca. 330 nm were obtained by controlling the polymerization conditions. They were then crosslinked with hydrazine solutions of various concentrations at
for 3 hours. Particles' sizes, size distributions, and thermal properties were then investigated. Crosslinking the PAN particles with hydrazine was shown not to affect the particles' sizes or distribution and it slightly lowered the degradation and cyclization temperature of the PAN.
