Processing process of long-acting antibacterial polyester filament yarn

Abstract

The invention discloses a processing process of a long-acting antibacterial polyester filament yarn. The processing process comprises the following steps: (a) cleaning and drying thermoplastic polyurethane slices, mixing the thermoplastic polyurethane slices with an antibacterial agent, adding the mixture into a screw extruder, and carrying out fusion and mixing; (b) adding a cross-linking agent in a metering stage of the extrusion or after the mixture is added into the extruder before entering a mixer; and (c) spraying out a fused spinning material by virtue of a spinneret plate, and carrying out spinning and winding formation. The product process comprises the following flows: slice cleaning, drying, extrusion, mixing, yarn spinning, traction, cooling, oiling and winding. The antibacterial agent is nano-scale silver powder. The processing process has the beneficial effects that the production is simple, the production efficiency is high, the investment is low, the product is relatively good in antibacterial performance, relatively strong in antibacterial durability, stable in quality and 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 polyester filaments. 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 ...

Problems solved by technology

[0003] At present, the polyester on the market is relatively common, and now there are more and more types of bacteria. Ordinary polyester does not have antibacterial function and cannot meet the needs of modern people. Therefore, an improved technology is urgently needed to solve the above technical defects.
