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 long-acting antibacterial vinylon filaments, comprising the following steps: a. Washing and drying thermoplastic polyurethane slices, mixing them with antibacterial agents and adding them to a screw extruder for melting and mixing; b. Measuring in the extruder The cross-linking agent is added after the extruder or before entering the mixer; c. The melt-spun material is sprayed out through the spinneret, spun and wound into shape, 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 silver powder, and the silver...

Abstract

The invention discloses a processing craft of a long-acting antibacterial vinylon filament. The processing craft comprises the following steps: a, cleaning and drying a thermoplastic polyurethane slice, mixing with an antibacterial agent, adding into a screw extruder, melting and mixing; b, adding a crosslinking agent on a metering section of the extruder or behind the extruder before entering a mixer; c, spraying out a melt spinning fabric through a spinneret plate, spinning, and winding to finally obtain a finished product. The flow of the production craft is as follows: cleaning the slice, drying, extruding, mixing, spinning, drafting, cooling, applying oil and winding. The antibacterial agent is silver powder, and the silver powder is nanoscale silver powder. The processing craft has the beneficial effects that the production is simple, the production efficiency is high, the investment is low, the antibacterial performance of the product is relatively good, the antibacterial durability is relatively strong, the quality is stable, and the processing craft is easy to popularize.

Description

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