Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with specific embodiment and accompanying drawing: As shown in accompanying drawing 1, the fiber section of composite polyester filament of the present invention is a sheath-core composite structure, and it is made of common polyester core Layer A and cortex B composed of functional polyester with negative oxygen ions and far infrared functions; the function of cortex B is to permanently release negative oxygen ions, emit far infrared rays, antibacterial and deodorizing and other functions. The role of the core layer A is to maintain the strength, elongation and spinnability of the fiber with good post-processing performance. The functional polyester filament better realizes the quality (strength, elongation, processability) and functionality of the fiber. Index (releasing negative oxygen ion concentration 4000 / cm 3 Above, far infrared emissivity above 0.88 and antibacterial and deodorizing effect) p...
