Development of Nylon Sportswear Fabrics by Composite Spinning

Abstract

This study surveys to develop multi-functional nylon sportswear fabrics by composite melt spinning technology. Nylon multi-functional garment with light weight, quick drying and heat-insulating properties has been developed by using hollow filaments. The light weight and good quick drying properties are needed for making high added value nylon fabrics for multi-functional garment. For getting these properties of nylon fabrics, spinning, weaving and fabric reduction technologies as an elution have to be considered. For this purpose firstly composite spinning technology with polyester and nylon conjugate structure has been studied. Multi-functional nylon high hollow filament was developed by application of high reduction technology to the PET in a core part. The reduction conditions such as concentration of NaOH, bath temperature and reduction time are chosen. The physical properties of the various eluted filaments are measured and discussed with various elution conditions. And then the nylon sportswear fabrics are woven by using nylon hollow filament reduced with various process conditions, the mechanical properties of this fabric are measured using KES-FB system, and these mechanical properties are discussed with various process conditions.
