Abstract

The invention relates to an ecological antibacterial high-sensitivity polyester fiber and a method for producing the same. The method includes particular steps of (1), preparing ecological antibacterial high-sensitivity master batch from efficient antibacterial agents, modified bamboo charcoal powder and polyethylene glycol by the aid of double-screw melt blending extrusion processes; (2), preparing ecological antibacterial high-sensitivity polyester fibers, to be more specific, spinning and extruding conventional polyester chips by the ecological antibacterial high-sensitivity master batch prepared at the step (1) by the aid of melt blending spinning processes via spinning assemblies, cooling virgin fibers by means of circular air blowing, applying oil to clusters and carrying out drawing, heat-setting and winding to obtain the ecological antibacterial high-sensitivity polyester fiber. The ecological antibacterial high-sensitivity master batch is used as a modification auxiliary at the step (2). The ecological antibacterial high-sensitivity polyester fiber and the method have the advantages that the antibacterial performance of the ecological antibacterial high-sensitivity polyester fiber include that the antibacterial rate of the ecological antibacterial high-sensitivity polyester fiber for staphylococcus aureus is higher than 90%, and the antibacterial rate of the ecological antibacterial high-sensitivity polyester fiber for Escherichia coli is higher than 92%; the far infrared emittance of the ecological antibacterial high-sensitivity polyester fiber is higher than 85%.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of functional polyester fibers, in particular to an ecological antibacterial high-sensitivity polyester fiber and a production method thereof. [0003] 【Background technique】 [0004] In the field of home textiles and decorative textiles, antibacterial properties are the most important indicators. However, the currently used synthetic fibers do not have antibacterial properties, so external antibacterial agents are often used for antibacterial modification of fibers; the current preparation methods It is mainly post-processing, and the antibacterial properties of fibers or fabrics are modified by coating and finishing fibers or fabrics with antibacterial agents on the surface and finishing them with antibacterial oils. The substrate with polar functional groups has a very good effect, and the ionic bonding between polar functional groups is used to improve the adhesion of the finishing agent. However...
