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 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.

Abstract: As available energy sources have grown increasingly scarce, people have started paying attention to their energy consumption. Although many methods for power generation are being actively investigated, efficient methods for solving energy problems must be based on reducing energy consumption. Thermal insulation can decrease heat energy loss and conserve energy waste, especially in the construction, transportation and industrial fields. In this study, polyester (PET) hollow fibers were blended with various ratios of low-melting-point PET fibers (10%, 20%, 30%, 40% and 50%). The fibers were blended using opening, carding, laying and needle punching (150 needles/cm2, 225 needles/cm2 and 300 needles/cm2) to prepare PET nonwoven fabrics. The PET nonwoven fabrics were thermally plate pressed (TPP) and air-through bonding (ATB). Thermal conductivity, physical properties and air permeability were investigated to identify the influence of manufacturing parameters on the PET nonwoven fabrics. The experimental results show that needle punching density, TPP and ATB would influence the thermal conductivity of PET nonwoven fabric, because the structure of PET nonwoven fabric was changed. The optimal parameters of PET nonwoven fabric clipped with an aluminum foil was used to evaluate the influence of aluminum foil on thermal conductivity. The PET nonwoven composite in this study can be used in industrial thermal insulation applications.
