Embodiment 1

[0026] Pre-mix the dried PP powder and ZAO (Zn:Al molar ratio 95:5, particle size 100-200nm) powder evenly according to the weight ratio of 95:5, put them into the nine-stage temperature control In the twin-screw, the temperature of each section from the feed port to the discharge port is 170 ° C, 185 ° C, 200 ° C, 210 ° C, 220 ° C, 210 ° C, 200 ° C, 190 ° C, 180 ° C, blending extrusion, After granulation by a pelletizer, masterbatches are obtained, then the masterbatches are dried, put into a melt spinning machine, and spun. The diameter of the spinning head is 0.3mm, the spinning head is 28 holes, and the spinning temperature is 230°C. The spinning speed was 400m. The as-spun silk is then drawn with a parallel drawing machine, the drafting ratio is 3.3 times, the temperature of the front roll of the drawing machine is 70°C, and the heating temperature is 100°C. After drawing, PP / ZAO composite functional fibers are obtained.

Embodiment 2

[0028] The dried PP powder and ITO (In:Sn molar ratio is 90:10, particle size is 50-100nm) powder are pre-mixed evenly according to the weight ratio of 97:3, and put into the five-stage control In the warm twin-screw, the temperature of each section from the feed port to the discharge port is 170°C, 210°C, 215°C, 220°C, 180°C, blended and extruded, and pelletized by a pelletizer to obtain master batches , and then dry the masterbatch, put it into the melt spinning machine, and carry out spinning. The diameter of the spinning head is 0.3mm, the spinning head is 48 holes, the spinning temperature is 240°C, and the spinning speed is 400m. The as-spun silk is then drawn with a parallel drawing machine, the drafting ratio is 4 times, the temperature of the front roll of the drawing machine is 70°C, and the heating temperature is 100°C. After drawing, fibers with low infrared emissivity are obtained.

Embodiment 3

[0030] Pre-mix the dried PP powder and ATO (Sn:Sb molar ratio is 97:3, particle size is 50-100nm) powder according to the weight ratio of 99:1, put them into the nine-stage temperature control In the twin-screw, the temperature of each section from the feed port to the discharge port is 170°C, 185°C, 200°C, 210°C, 220°C, 210°C, 200°C, 190°C, 180°C, blending and extrusion, after Pelletizing machine to obtain masterbatch, then dry the masterbatch, put it into the melt spinning machine for spinning, the diameter of the spinning head is 0.3mm, the spinning head is 36 holes, the spinning temperature is 235°C, the spinning The wire speed was 400m. The as-spun silk is then drawn with a parallel drawing machine, the drafting ratio is 4 times, the temperature of the front roll of the drawing machine is 70°C, and the heating temperature is 100°C. After drawing, fibers with low infrared emissivity are obtained. After spinning and drawing, fibers with low infrared emissivity are obtaine...

Abstract

The invention relates to a polypropylene / doped oxide composite functional fiber preparation method, comprising the following steps: (1) mixing the dried polypropylene matrix and the oxide powder evenly; (2) adjusting the temperature of a twin-screw extruder to 160-220 DEG C, adding the mixed powder, squeezing out, cooling, cutting into grains and obtaining spinning masterbatch; (3) adding the masterbatch in a spinning machine to obtain freshly formed filament; (4) drafting the freshly formed filament with a extension drawing ratio of 2-6 times to obtain the composite functional fiber of the invention. The preparation method of the invention has simple production equipments and easy-realizable industrialized production, the composite functional fiber prepared by the invention has the functions of absorbing electromagnetic wave, reducing infrared emissivity, restraining bacteria, resisting ultraviolet radiation, preventing aging and the like, and the fiber can be widely used in various fields such as textiles with the functions of preventing electromagnetic wave radiation, restraining bacteria, resisting aging and resisting static electricity and the like.

Description

technical field [0001] The invention belongs to the field of preparation of composite functional fibers, in particular to a preparation method of polypropylene / doped oxide composite functional fibers. Background technique [0002] With the development of science and technology and the progress of society, electromagnetic radiation has become another source of pollution, which is harmful to people's health. In addition, people's requirements for textiles are gradually increasing. Therefore, the development of electromagnetic wave absorption, antibacterial, antistatic, anti-ultraviolet functions Fiber is already very necessary. [0003] For example, patent CN1442518A will TiO 2 , CuS and other nano-antibacterial powders and viscose fibers are combined to prepare anti-bacterial fibers. Patent CN1278032A reports the anti-static and anti-ultraviolet functional fibers made of composite nano-metal particles such as metal nickel and polyester, Journal of Polymer Research (2007) 14...
