摘要

This paper deals in general with fabrics consisting of bicomponent fibers that are fractured and bonded by Hydroentangling to form micro-denier fibers. Spunbonding process using bicomponent filament technology, where two compatible polymers are extruded together to produce continuous filament webs has been discussed. This process of nonwoven fabric manufacture combined with the fiber fracturing process using Hydroentangling is discussed. In particular, this paper deals with the bonding energy requirements for modified 'Islands-in-the-Sea' filament cross-sections that enhance the fracturing of such filaments. This technology can be used to produce micro- and nanofiber webs that have considerably higher surface area. Two different compatible polymer systems (Polyester/Nylon and Nylon/Polyethylene) were explored. Optimal bonding conditions for the fabrics were identified.
