THE STRUCTURE AND PROPERTIES OF FINE DENIER HOLLOW POLY(ETHYLENE TEREPHTALATE) FIBRES

Using brighten white and modified PET chips, fine denier hollow fibres (dpf=0.5～1.5) were prepared on a Fuji Filter MSTC-400 and VC-443A drawn machine, whose structure and properties were tested by X-ray diffraction mater, SOM-II sonic velocity meter and Instron-1122 Tensile tester, electron and light microscopy etc,. The results show: fine denier hollow taken-up yarns prepared at low spinning velocity have radial orientation, higher strength and elongation at rupture because radial stress is higher than normal stress. Fine denier hollow drawn yarns with hollow degree up to 18～35％ and high tenacity, together with high crystalline degree and small crystal and amorphous domains, can be empolyed as products.

Principles and Chief Technologies in Developing Light-weighted Worsted Fabrics

More and more light-weighted fabrics are being required by the market, especially for the worsted manufacture. In the past, such fabrics are produced mainly through changing the structure of woven goods or by using finer yarns. But these possibilities are very limited. In this paper, new devices are discussed: (1) on the yarn level - to use single yarns instead of conventional doubled ones, to decrease number of fibers in yarn cross sections both during spuming and after finishing; (2) on the fiber level - to use finer fibers in blends with wool and modification of the wool fibers; (3) on the macromolecule level - to stretch the macromolecules in alpha keratin, to get super fine wool fibers.
