Embodiment 1

[0044] Take 5kg of antibacterial polyester masterbatches with a concentration of 15%w, 20-60nm silver, zinc, and silicon-based oxides, put them in an enamel plate, with a stacking thickness of 10cm, put them in a vacuum oven, heat up to 85°C, and keep warm for 2 hours. Slices are pre-crystallized. Continue to heat up to 105°C, keep warm for 5 hours, turn off the power, and cool naturally, with a moisture content of 50ppm.

[0045] With the addition of 4.7% nano-antibacterial masterbatch, adjust the frequency of the injection machine to 45.5Hz, evenly transport it to the feed port of the extruder, mix it with polyester dry chips, enter the screw extruder to heat, melt and compress, and control the display table Temperature, zone I 295°C, zone II 302°C, zone III 299°C, zone IV 296°C, zone V 293°C, biphenyl furnace temperature 287°C, head melt temperature 295°C, melt pressure 100bar, by rotating screw The extruded blended melt enters the metering pump through the distribution pipe...

example 2

[0047] With the addition of 5.7% nano-composite antibacterial polyester masterbatch, adjust the frequency of the injection machine to 54Hz, and evenly transport it to the feed port of the extruder to mix with the polyester dry slices, and then enter the screw extruder to heat, melt, compress, and control the display table Temperature zone I is 293°C, zone II is 298°C, zone III is 296°C, zone IV is 294°C, zone V is 291°C. The melt pressure of the machine head is 100bar, the melt temperature is 293°C, and the temperature of the biphenyl furnace is 285°C. The blended melt extruded by the rotating screw enters the metering pump through the distribution pipe and the static mixer, and is delivered to the nozzle at a rate of 55g / min. The silk assembly is filtered, homogenized, and evenly distributed through a 50-mesh and 60-mesh sea sand layer, pressed into a 36f spinneret to form a thin stream of melt, cooled and formed in a 27°C silk room, and then the surface of the tow is coated w...

Abstract

The invention relates nano composite polyester blending high-speed spinning method, comprising the following steps: drying the nano composite antibiosis polyester mother granule, mixing the mother granule and polyester, melting, spinning, cooling, supplying fuel, high-speed stretching, winding and getting the nano composite antibiosis polyester. The invention provides the method of spinning new pattern nano composite antibiosis polyester. The method is simple process flow, low cost, high product quality, good bacteria repellency and long-acting.

Description

technical field [0001] The invention relates to a spinning method of antibacterial polyester fiber, more precisely, it relates to nanocomposite antibacterial polyester masterbatch and the selection of addition amount thereof and the steps of blending high-speed spinning method. The invention belongs to the field of nano functional fiber preparation. Background technique [0002] Nano is used as a measure of material, and its size is 1nm=10 -9 m. Nanomaterials are materials whose constituent phases or grains are smaller than 100 nm in any dimension. Nanomaterials are divided into nanoblocks, nanomembranes, and nanofibers according to their macroscopic structures. Among them, nanofibers are divided into two categories according to the processing method: 1. Materials whose fiber diameter is nanoscale, such as carbon nanotubes. 2. Fibers made of fiber-forming polymers filled with nano-scale metals, non-metals and other materials, such as nano-scale far-infrared fibers. [0...
