Abstract: The bite of Forcipomyia taiwana (F. taiwana) causes intense pruritus and swelling in sensitive skin. Most commercially available F. taiwana repellents are made of N, N-diethyl-3-methylbenzamide synthetic repellents [; however, using them for a long time influences skins, and the nervous and immune system. This study uses the water extracted Cinnamomum osmophloeum Kaneh and Cymbopogon excavates for the Y-tube test, determining the repellent effect of these two extracts and the influence of water extract time on the difference in their repellent effect.

Abstract: According to the results, when low melting polyester fiber increased to be 20%, the electromagnetic shielding/ far infrared ray nonwoven obtained the optimum burst strength, maximum breaking force and maximum tear strength, and they were as follows: burst strength was 4.2 kgf/cm2; maximum breaking force was 153.59 N in the cross machine direction and 70.80 N in the machine direction; maximum tear strength was 215.77 N in cross machine direction and 117.07 N in machine direction; and optimum electromagnetic shielding effectiveness (EMSE) was 45 dB.

Abstract: Chitosan (CS) and gelatin (G) both have good biocompatibility and biodegradation, qualifying them for use in tissue engineering. In this study, CS and G are blended with different ratios to make the mixture solution, and then freeze-dried to form three-dimensional porous CS/G bone scaffolds. The surface, cross-section, porosity, and pore size of the resulting bone scaffolds are observed and analyzed. According to the experimental results, the addition of gelatin gives the CS/G bone scaffolds morphology with few pores. As can be seen from SEM observation, there are linear pores in the cross-section. In addition, with a larger quantity of gelatin, the CS/G bone scaffolds have a lower porosity.

Abstract: This study proposes coronary stents in a manner of reticular tube, which are made by applying a braiding method. Polyvinyl alcohol (PVA) plied yarns are braided into hollow braids on a 16-spindle braid machine, followed by being cross-link treated to form the coronary stents. The surface observation and a compressive test are used to evaluate the resulting products. The test results show that cross-link treatment does not pertain to the reticular, tubular manner of the braids. However, a low cross-linking concentration results in a light shade and a greater compressive strength in the coronary stents. In addition, the acidification of the cross-linking solution affects the compressive modulus. The coronary stents presented by this study are proved to be biodegradable and have compressive strength and a reticular-and-tubular form.

Abstract: The compound fabrics comprised of double layers of nonwovens and carbon fabrics were prepared by needle-punching and thermal bonding techniques. The thermal bonding and number of layers effect on thermal insulating and sound absorbing property have been discussed. The resulting compound fabrics have thermal conductivity decreases to 0.02 W/(m*K) for single layer of thermo-bonded compound fabrics and sound-absorbing coefficient reaches to 0.848 at 4000 Hz for 3-layer un-thermo-bonded fabrics .

Abstract: Calcium phosphate bone cement (CPC), a bioceramic, is commonly used in artificial bone scaffold for impaired bones. In this study, CPC is mixed with polylactide (PLA) fibers and porogenic agent to form CPC/PLA composite bone scaffold. The compressive strength of the resulting bone scaffolds is evaluated and the fractured cross-section is observed by a scanning electron microscope (SEM), thereby determining the influence of fiber length. The experimental results show that the shorter the fiber is, the greater the compressive strength is.

Abstract: In recent years, as global technical progress grows, many mechanized machines are developed continuously. Mechanization has substituted for manpower in many factories for promotion of production efficiency, leading to mechanical noise happening more severely. If people are subjected to noise pollution for long term, they would happen dysphoria and absent mindedness, resulting in accident occurrence. Therefore, how to effectively reduce noise pollution becomes an urgent subject. Moreover, rapid population development and fast-growth economy raise consumption in every country, driving industry into high-production and high-consumption times and meanwhile generating much of wastes. In order to achieve sustainable development, these wastes should be recycled effectively. Therefore, 20 wt% recycled PET fibers were added in this study. This paper mainly used 3D and 15D Nylon fibers (70, 60, 50, 40, 30 wt%), low-melting PET fibers (10, 20, 30, 40, 50 wt%) and 20 wt% high-strength PET fibers, to fabricate Nylon 6/Low melting PET/ Recycled high-strength PET nonwoven via needle-punching process. After that, tensile strength, air permeability and sound absorption coefficient property of resulting nonwoven were tested and then evaluated respectively.

Abstract: Polylactic acid (PLA) fiber, as a biodegradable synthetic aliphatic polyester fiber, has properties of biocompatibility, biodegradability and processing. Therefore, this study used PLA multifilament to prepare numerous plied yarns, respectively 75D, 75D×2, 75D×3, 75D×4 and 75D×5. Afterwards, these yarns were twisted with 3, 5, 7 twist/inch and then heat-treated respectively. The resulting yarns were tested for their tensile property tensile tenacity and tensile elongation. Moreover, the heat-treated effect was discussed on influencing tensile property.

Abstract: Twisting has an influence on not only the strength, luster, softness, and elasticity of the yarns, but also the properties of the resulting fabrics. This study aims to evaluate how the rotor twister speed and the thermal treatment temperature influence the properties of the polyethylene terephthalate (PET) plied yarns and wrap yarns. Both yarn types are made with a twist coefficient of 1, 1.5, or 2, and then thermally treated in an oven at 70, 110, and 150 °C. The resulting plied yarns are wrap yarns are tested for tensile strength and elongation, and their surface is also observed by a stereomicroscope to determine the influences of the two parameters. The results of the experiment show that twist coefficient does not influence the tensile strength nor the elongation. The tensile strength of various plied yarns and wrap yarns is approximately 4.4cN/dtex; the variation in the twist coefficients is too small and thus hardly causes any significant differences in the yarns properties.

Abstract: Freeze-drying method can create three-dimensional, porous structure bone scaffolds, the pore size of which can be changed by a cross-linking agent. This study dissolves chitosan powder in a 1 v/v % acetic acid aqueous solution to form a 2 w/v% chitosan solution. The chitosan solution and a 4 w/v % gelatin aqueous solution are blended to form Chitosan/Gelatin mixture, after which the mixture is frozen at-20 °C for 1 hour, removed, and cross-linked with a 0.5 v/v % 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC) solution for different durations. The cross-linked mixture is frozen at-20 °C for 1 hour and then freeze-dried for 24 hours to form Chitosan/Gelatin composite bone scaffolds. A stereomicroscope and a scanning electron microscopes (SEM) and Image Pro Plus are used to observe the surface and pore size of the bond scaffolds, and in vitro evaluates their biocompatibility. The experiment results show that resulting bone scaffolds possess a uniform pore distribution a desirable biocompatibility.
