Mechanical and Physical Analysis of Kenaf Nonwovens Textile Subjected to Different Needle-Punched Processing Parameter
Kenaf mat processed using needle-punching technology have shown potential mechanical and physical attributes for diverse applications. A proper understanding is required to understand the relation between the machine parameters and fabric properties in designing a fabric. Hence, this project will be focused on the different machine parameters which are the fiber feeder speed and the number of ply. Samples were produced by needle-punched nonwoven machine varying three speeds of feed roller. The fabrics were stacked in 2 and 3 plies and fabric thickness was constant of 5mm. The tests conducted include areal density, porosity, tensile strength and bursting strength. The results were satisfying and showed that kenaf needle-punched properties are adjustable to desire properties depending on the application. It is proven that the fiber feeder speed can affect the mechanical and physical properties. As the speed of the roller increased, the mechanical ability increases due to greater penetration of needle but porosity reduced as high speed of roller produced lower number of entanglement. The addition of ply also affects the performance by further increasing of mechanical strength and reduced porosity.
