Abstract: In order to fabricate textiles with electromagnetic shielding effectiveness (EMSE) and far infrared emissivity, we fabricated bamboo charcoal/metal (BC/M) composite wrapped yarns with metal wires (stainless steel wires or copper wires) as the core yarn and bamboo charcoal textured yarn as the wrapped yarns using a rotor twister machine. The optimum manufacture parameters included: the speed of the rotor twister was 8000 rpm and the wrapped amounts of the BC/M composite wrapped yarns were 4 turns/cm. The BC/M composite wrapped yarns were made into the BC/M composite woven fabrics using a loom machine. Moreover, we tested the BC/M composite woven fabrics in EMSE and then changed the lamination angles. When the lamination amount was 6, laminated angles were 0°/45°/90°/-45°/0°/45°, 0°/ 90°/0°/ 90°/0°/ 90°, and the frequencies of the incident waves were between 1.83 and 3 GHz, the EMSE of the BC/M composite woven fabrics reached 50 to 60 dB which was satisfactory.

Abstract: This study designed a flexible electromagnetic resistant fabric it is not only apt to make protective clothing, but also simple process dependence on its application. Polylactide fiber (PLA) and the low melting polylactide fiber (LMPLA) were blended to fabricate nonwoven matrix. Then polyester (PET) aluminum foil inserted between two layers of PLA nonwoven matrix to fabricate a compound matrix by needle punching. Afterward, physical properties and electromagnetic shielding effectiveness of different layers compound matrix were be evaluated.The result indicated that Tensile strength of sample B was 189.16 N; tear strength of sample C was 579.43 N. Burst strength of sample B which was laminated five-layers compound matrix had best burst strength, 3326.18 N, and excellent electromagnetic shielding effectiveness, over 90 dB.

Abstract: d more to their own safety, lead all kinds of personal protection apparatus to rapidly develop. This study designed and manufactured the stabbing resistant fabrics to prevent the pricking damage of human body. In this study, woven Kevlar fabric is laid between two layers of polyamide 6 fibrous webs that contain low-melt polyester fibers. The fibrous webs and woven fabric are bonded via needle punching and thermal bonding to generate a nonwoven/woven composite fabric that can be used as a substrate for artificial leather. The polyamide 6 staple fiber is the primary component of the nonwoven structure. The low-melt polyester fiber was added via thermal bonding to reinforce the composite fabric structure. The stab resistance of the composite fabric was reinforced by the woven Kevlar fabric. Because the bonding process alters the mechanical properties of the composite fabric, effects of bonding process conditions, such as needle punching density and thermal bonding temperature, on the mechanical properties and stab resistance of the composite fabric were investigated. The stab resistance of the composite fabric was assessed by stab resistance tests using the ASTM F1432 standard. Experimental results demonstrate that the optimal parameters obtained from sample which needle punching density is 200 needles/cm2

Abstract: In recent year, the environmental consciousness is awakening; hence, the plastic recycling and reusing techniques have drawn much attention. In this paper, impact-resistant polypropylene(IRPP) chips were mixed with nano far-infrared master batches polypropylene(NFMPP) chips in different weight ratios. Then the polypropylene composite plates were formed by using a single screw extruder. Afterward, this study also simulated the plastics recycling procedure from 1 to 6 times, respectively. The results shown the average far-infrared emissivity of polypropylene composite plates were 0.90±0.02ε. In the IZOD measurement, the impact strength of polypropylene composite plate which processed for six times dropped by 20% comparing to the composite plate processed only once.

Abstract: Bamboo charcoal shows many advantages such as: moisture-proof foul smells reduction, the release of negative ion and far infrared ray, keep warm etc. For the purpose of increasing disersification, comfortable and beautiful feeling of the fiber efficiency, it already popularly applied to textile industry. This study used the elastic fibers as core yarn that was covered with polyester textured yarn contained bamboo charcoal to produce covered yarn. Elastic yarn was draw for suitable ratio and then covered with polyester yarn to form covered yarn, different draw ratio worked by changing roller speed, adjust twist number by controlling take up roller speed and twister speed of covering machine to get ideal stretch power were studied. Experiment results indicated that maximum break strength (4.52gw/denier) that when the speed of the rotor is 6000rpm while drawing ratio at 350%, twist number 2turns/cm. Maximum breaking elongation (24.57%) could get at speed of the rotor is 4000rpm when drawing at 350%, twist number 4.5turns/cm.

Abstract: The nonwoven waste coming from textile industry takes up 5% of the total waste amount, so to recycle and to regenerate the waste is the prior obligation of the factory to reduce the waste. Nonwoven selvages waste can be buried or burnt but these two methods result in environmental pollution. This research proposes to reuse these waste nonwoven selvages effectively, and is designed as follows. Each piece of thermal-bonding material comprised a sandwich structure, with two layers of 7.0d PET matrices enclosing a layer of PP nonwoven selvage and nylon geogrid. After needle-punching and thermal-pressing, it forms a laminate structure of PET nonwoven/ PP selvage/ PET nonwoven in that it decreases the impact by the environmental pollution and protects the environment ultimately. In addition, thermal-bonding reinforces the mechanical properties of the composite fabric structure. The results of the experiment suggest the optimum manufacture parameters (selvage content: 10 %; thermal-bonding temperature: 220°C; needle-punching density: 400 needles/ cm2). The composite fabric undergoes the burst strength test and permeable coefficient measurement, evaluating its applications in geotextile filed.

Abstract: In this study, the basic material for sound absorption was porous nonwoven made of polyester nonwoven and low-melting polyester fiber. Nonwoven was then attached with foam polyurethane as composite plank for sound absorption and sound isolation. We used two microphone impedance tubes for sound absorption test and INSTRON 5566 mechanical testing machine for tensile test. The optimum sound absorption coefficients as 0.67 ± 0.008 was obtained when density of foam polyurethane was 1.0 Kg/m3 with thickness of 20 mm; Polyester nonwoven were 9 layers; and low-melting polyester fiber was 30 wt% with thickness of 10 mm. Specimens obtained the maximum fracture stress when it contained low-melting polyester fiber at 30~40 wt%. The results of this study could be applied in the partitions inside ships, vehicles or buildings.
