Currently, various products containing bamboo charcoal are popular. In this study, thermal insulation composites were manufactured with PET non-woven fabrics and bamboo charcoal woven fabrics. Bamboo charcoal can radiate far infrared rays and absorb smells, so it is used for textiles, deodorant materials, bedding, pillows, and so on. Non-woven fabrics were made with hollow and spiral polyester staple fibers, and had superior thermal insulation. The mechanical properties, thermal conductivity, and air permeability of the composites were evaluated. When the ratio of the low melting point fibers was 30%, the maximum breaking strength of the thermal insulation composites exceeded that in any other ratio conditions. Moreover, the thermal insulation of the composites was superior when the ratio of the low melting point fibers decreased. The air permeability of the thermal insulation composites increased with decreasing ratios of the low melting point fibers. The thermal insulation composites can be used in daily commodities and industrial products.

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

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.

To satisfy the many requirements of our daily life, complex textiles that are both functional and beneficial have been successfully designed and developed. This research investigates the design of bamboo charcoal/spandex (BC/S) complex yarns, fabricated with a blend of spandex and bamboo charcoal polyester textured yarn, which possess superior elastic recovery. The expansion multiples of the spandex was 1.5-3.5, the wrap counts are 2-4.5 turns/cm, and the speed of the rotor twister was 4000-12000 rpm. When the speed of the rotor twister was between 4000 and 12000 rpm, the expansion multiple was 1.5 and the elastic recovery rate was maintained at 93% or above. Furthermore, the far infrared emissivity of BC/S complex knitted fabric was over 0.9, but descended with the lamination number. The BC/S complex knitted fabric also contained an anion count of 356 anions/cc.

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.
