Textile Science and Engineering, volume 46, issue 4, 2009, Pages 193~199
PVA/collagen blend fibers were produced by air-gap spinning method, and were successfully spun to blend fiber. Maximum collagen content to produce the fiber was 30%, above which the fiber was found to be broken in the drawing process. Thermal and mechanical properties of the fibers were investigated by changing blend ratios of the PVA to collagen. Melting point of PVA was decreased with the increase of the amount of collagen. The strength and the elongation of the fiber were also decreased due to the inhomogeneous structure of the blend fiber. Hot water resistance was endowed by the heat treatment after drawing process, and when the fiber was treated at
for 10 minutes, it was neither swelled nor broken in boiling water.

Hydrogel is prepared using triblock copolymer of poly(ethyleneoxide-propyleneoxide-ethyleneoxide) with different block contents. Each hydrogel showed different rheological and thermal behavior according to the conditions of gelation such as solution temperature, the content of block copolymer, and block ratio between ethylene oxide and propylene oxide. In this hydrogel system, poly(propyleneoxide) and poly(ethyleneoxide) acted as hydrophobic and hydrophilic domains, respectively. In aqueous solution, block copolymer acts as a surfactant, and then formed micelles due to the hydrophilic-lyophobic balance. These micelles aggregated and formed a lattice structure. In temperature sweeping using Rheometer, transition of aqueous block copolymer solution was developed from a liquid state through soft-gel state to hard-gel state as increasing temperature. Hydrogels with different block ratio of PPO and PEO represent different sol-gel and gel-sol transition point.

This study analyzes a hydraulic performance of GCL (geosynthetic clay liners) with and without swelling accelerating material, SAP(Super Absorbent Polymer). In the evaluation of hydraulic performance of GCL, free swell index and triaxial compression permeability tester were used by falling head permeability tester in the evaluation of hydraulic performance with the mixed soil of decomposed granite and bentonite. Permittivity of weathered granite soil and bentonite mixture was increased with SAP content and permeability of this mixture soil was also increased till bentonite content 10%.

It is important for automobile manufacturers to eliminate unwanted noise in passenger compartments of vehicles. One of the methods free from noise is to use sound absorbing materials such as floor coverings, package trays, door panels and luggage compartments in auto interiors. In this study, the needle punched nonwovens were produced with the various blending ration of Non-circular shaped polyester, 2 denier and splittable micro-fiber, 2 denier. The sound absorption characteristic of nonwovens and corresponding mechanical properties are explored.

Textile Science and Engineering, volume 46, issue 4, 2009, Pages 215~221
This research reports on the bundle drafting characteristics on the basis of a mathematical model describing the bundle flow dynamics. And the model parameters were experimentally measured or estimated. The kinematic viscosity of bundle was measured experimentally and the velocity variance parameter was estimated by comparing results from the experiment and from the simulation. The step response of the output bundle thickness to a step change in the draft ratio was applied. The kinematic viscosity of bundle was confirmed to be in the range between
, which depends on the process conditions. As the draft ratio increases, the viscosity decreases dramatically in a low level of the draft ratio, but a draft ratio higher than 10 causes a very slow change in the viscosity, which is again affected by the roller setting. The kinematic viscosity remained, however, almost unchanged in the level of the roller setting longer than 45 mm. Under the draft ratio larger than 10, a high viscosity and a low velocity variance of constituent fibers had the effect to make the stability area narrower. Therefore the analysis results of bundle flow stability indicate that the draft ratio should be adjusted as small as possible in the high draft ratio level larger than 10 and the entanglement of the bundle be minimized for a large value of the velocity variance parameter, if the bundle flow system is maintained in a dynamic stable state.

This study deals with developing a measuring system which can provide with information on the weaving performance of warp yarns, which works on the basis of a physical simulator. To reach the initially purposed intention, we measured the warp yarn tension. The measured signal was processed to produce the dynamic average tension, maximum and minimum tension values, and the tension change slope with respect to test cycles, etc.. Results revealed that information on the weaving performance factors such as hair occurrence, entanglement of warp yarns, yarn breakages, and the warp yarn tension relaxation as well could be extracted from the measured tension behavior of the warp yarns, which let the evaluation of the weaving performance of new warp yarns be conducted without direct loading of the yarns on the weaving machine so that the time and material required for weaving fabrics with new warp yarns can be drastically reduced.

Since nonwoven fabrics are made of irregular assembly of fibers, it is difficult to predict the mechanical properties of the fabrics from those of their constituent filers and their structure. In this paper, we propose a simulation algorithm for mechanical properties of spun-bonded nonwoven fabrics from the fiber properties and the structure of the fabrics. The algorithm requires simplified structure of spun-bonding structure which can be easily determined by microscopic image and fiber modulus. It is assumed that the number of fibers connecting bonding sites can represent the structure of the fabrics, including the information of fiber orientation in a discrete manner.

In this study, junction strength, stress distribution of geogrids and wide-width tensile behaviors were interpreted by Visual FEA/Edu program as finite element analysis. Through comparison to test values, it is examined whether the validity of prediction values by Visual FEA/Edu program was reasonable or not. For stress distribution effect of cross machine direction ribs, warp knitted type showed better than woven type. Through contour image from the results of finite element analysis, the stress change in adjacent point around the ribs could be predicted. For analysis of tensile behaviors, prediction data of finite element analysis is dependent on the tensile test data and how to devide elements and consist the finite element network of geogrids.
