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...

Abstract

The composite functional polyester filament is one composite structure comprising one core layer of common polyester and one coating layer of functional modified polyester with functions of releasing negative oxygen ion and emitting far infrared ray, with the linear density ratio between the coating layer and the core layer being 2:8 to 4:6. The functional modified polyester for the coating layer can release negative oxygen ion in over 4000 / cu cm for long term and has far infrared emissivity over 0.88. The composite functional polyester filament is produced in a double screw composite spinning machine, and has one coating layer to release negative oxygen ion and emit far infrared ray for long term and one core layer with high mechanical strength.

Description
