Embodiment Construction

[0010] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0011] A process for processing antibacterial polyester filaments, comprising the following steps: a. Washing and drying thermoplastic polyurethane chips, mixing them with antibacterial agents and adding them to a screw extruder for melting and mixing; b. Add cross-linking agent after the extruder and before entering the mixer; c. The melt-spun material is sprayed out through the spinneret, spun and wound to form, and finally the finished product is obtained.

[0012] The production process is: slice cleaning—drying—extrusion—mixing—spinning—drawing—cooling—oiling—winding.

[0013] The antibacterial agent is copper powder, and the copper powder is nanoscale copper powder.

[0014] The i...

Abstract

The invention discloses a processing process of antibacterial polyester filaments. The processing process comprises the following steps: (a) slicing thermoplastic polyurethane, cleaning, drying, then mixing with an antibacterial agent, adding into a screw extruder, melting and mixing; (b) adding a cross-linking agent at a metering section of the extruder or after entering the extruder and before entering a mixer; and (c) spraying melt-spun materials by using a spinneret plate, spinning, winding and forming, thus finally obtaining a finished product. The production process comprises the procedures of slicing and cleaning, drying, extruding, mixing, spinnereting, drawing, cooling, oiling and winding. The antibacterial agent is copper powder which is nanoscale copper powder. The processing process disclosed by the invention has the beneficial effects that the production is simple, the production efficiency is high, the investment is low, and the product is better in antibacterial performance, stronger in antibacterial persistence, stable in quality and easy in promotion.

Description

technical field [0001] The invention relates to the technical field of chemical fiber processing, in particular to a processing technology of antibacterial polyester filament. Background technique [0002] There are many kinds of chemical fibers. Polyester is one of the more common ones. The production technology of polyester can be divided into 4 types: dry spinning, wet spinning, reaction spinning and melt spinning. No matter what kind of spinning process is used, the properties of the produced chemical fibers are basically the same, most of them are white filaments, and the cross-sectional shape varies according to the production process. Dry-spun polyester filaments are mostly round and oval-shaped dumbbell-shaped cross-sections; wet-spun and chemical-spun polyester filaments are mainly thick leaf-shaped and irregular cross-sections, and there is no hesitation between the filaments. Irregular bonding points are formed, thereby forming bonded multifilament bundles; melt-...
