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 processing technology for antibacterial spandex filaments, comprising the following steps: a. Cleaning and drying thermoplastic polyurethane slices, 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.

Abstract

The invention discloses a processing technique of an antibacterial polyurethane filament. The processing technique comprises the following steps: a, cleaning thermoplastic polyurethane chips, drying, mixing the dried thermoplastic polyurethane chips and an antibacterial agent and adding the mixture into a screw extruder for fusing and mixing; b, adding a cross-linking agent at a metering segment of the extruder or behind the extruder before entering a mixer; c, spraying a melt spinning material, spinning and performing winding formation with a spinneret plate, so as to obtain a finished product. The technological process of production comprises: cleaning of the chips, drying, extruding, mixing, spinning, drafting, cooling, oiling and winding. The antibacterial agent is copper powder which is nanoscale copper powder. The processing technique has the beneficial effects of being simple in production, high in production efficiency, low in investment, relatively good in antibacterial property of a product, relatively strong in antibacterial endurance, stable in quality and easy in popularization.

Description

technical field [0001] The invention relates to the technical field of chemical fiber processing, in particular to a processing technology of antibacterial spandex filament. Background technique [0002] There are many kinds of chemical fibers. Spandex is one of the more common ones. The production technology of spandex 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 spandex filaments are mostly round and oval-shaped dumbbell-shaped cross-sections; wet-spun and chemical-spun spandex 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-spun spand...
