Problems solved by technology

For example, the Chinese patent application number is 03115681.9, titled: "A Conductive Fiber and Its Preparation Method", which discloses that the conductive fiber is composed of polyethylene terephthalate glycol, polyethylene vinyl acetate and conductive carbon black. The content of carbon black in the fiber is low, and the conductive effect is good; the disadvantage is that the dispersion of the conductive powder in the carrier resin is poor, and the spinnability is average.

Embodiment Construction

[0014] The present invention will be further described below with reference to the embodiments and accompanying drawings. The preparation method of this special effect conductive fiber, its main steps are as follows:

[0015] (1) Masterbatch preparation:

[0016] Dry 500 grams of conductive carbon black at 95°C, put the dried carbon black into a high-speed mixer, add 3% coupling agent (CT-928) by spraying, and heat to 125°C , after high-speed stirring for 25 minutes, add dispersant respectively: polyethylene wax (2000) 10%; antioxidant: 1010 1.5%; DLTP 1.5%; magnesium stearate 3%; The ester powder was mixed at high speed for 15 minutes, and then cold mixed at high speed for 15 minutes before discharging. Put the above materials into the hopper of twin-screw extruder for twin-screw extruder, extrusion and granulation.

[0017] Its technological process (as shown in Figure 1):

Abstract

The invention relates to a kind of effective electric fibre. It contains: 5-9 %(w) electric charcoal parent-particle, 92-95%(w) PET polyester powder, and the electric parent-particle terylene, nitrile, or cotton fiber contains: 1-6%(w) selection-CT-928, 0 / 5-2%(w) 1010 and 0.5-2%(w) PLTP (antioxidant), 5-20%(w) dispersant-polyethene cere 2000 1-5%(w) magnesium stearic acid. The preparation method is: first, use electric charcoal as the electric component, and separate it evenly is polyester carrier by enwrap and disperse. Secondly produce the parent-particle by high-speed whisking, mix and extrude. Finally, use twin-screw to the filature and then obtain the electric fibre which has good peparative in ployester carrier. And the quality of spin is good. The invention has a low cost, high filature speed and good electric; the conductivity of one thread is 10000-1000000 ohm / cm.

Description

technical field [0001] The invention relates to the field of conductive fibers, and mainly relates to a high-efficiency conductive fiber and a preparation method thereof. Background technique [0002] The vast majority of polymer materials are insulating materials, and chemical fibers made of polymer materials, such as polyester, polypropylene, nylon, etc., also have insulating properties. These chemical fibers accumulate static electricity continuously during use, and the charge cannot be released, and eventually has a relatively high potential. The static electricity carried by chemical fibers will bring a serious threat to the safety production of gas stations, oil depots and some special occasions. Chemical fiber clothing also has adverse effects on human health due to frequent static electricity. [0003] To solve the adverse effects of static electricity of such chemical fibers, the main method at present is to try to make the originally non-conductive polymer synthe...
