Abstract
Winter outdoor clothing is aimed at protecting human being against harsh environmental conditions, especially against cold. Thermal insulating properties of a textile material plays significant role in protective clothing. Thermal protective clothing usually is a multilayer construction composed of three layers -Base layer, Insulating material, Outer layer. The previously available jacket insulating layer is always filled with down feather which cause harm to the wearer. This study concentrates on replacing the middle layer with ecofriendly natural Fiber-Kapok. Thickness, thermal conductivity, Air permeability, and wickability properties of fiber and fabric is determined. The layers are been bonded with Needle punching and thermal bonding technique. The effect of Multilayer clothing in cold weather is been tested and analyzed using different proportions of natural ecofriendly-kapok fiber.
