The invention relates to a polyester substrate powder containing a poly (butylene terephthalate) high molecular substrate, a uniformly dispersive nanometer carbon tube powder, a dispersion agent and a chain extending agent, a conductive batch with uniform and smooth surface, a method for preparing the conductive batch, a conductive single fiber formed by the conductive batch, a method for preparing the conductive single fiber, and a textile prepared from the conductive single fiber. The invention has the advantage that the nanometer carbon tube fiber material with high conductivity is prepared; and the spinning property of the conductive batch can be improved to avoid the phenomena of blockage and filament breakage in the spinning procedure.

Description

technical field [0001] The invention relates to a polyester substrate powder containing carbon nanotube powder evenly dispersed therein; a conductive masterbatch with a uniform and smooth surface and a method for manufacturing the conductive masterbatch; a conductive masterbatch made of the conductive masterbatch The formed conductive monofilaments and a method of making the same; and a textile made from the conductive monofilaments. Background technique [0002] It is known that carbon nanotubes are a kind of graphitized carbon tubes. The difference from ordinary carbon is that carbon nanotubes have L / D ratio characteristics and are the best conductive materials. Generally, when the L / D ratio is larger, the relative conductivity will be better, but if the L / D ratio is too large, there will be problems in the spinning process, for example, if the alignment or orientation is not good It will cause difficulties in spinning, and if the carbon nanotubes cannot pass the filter s...

AI Technical Summary

Problems solved by technology

[0007] 1) The procedure is too complicated and the cost is too high;

[0008] 2) Carbon nanotubes will lose their original properties after being destroyed by strong acid surface treatment, such as antistatic or electrical conductivity or strength will become worse;

[0009] 3) Carbon nanotubes are not easy to disperse in solvents, and the solvents used will cause environmental problems; and

[0010] 4) After carbon nanotubes are destroyed by strong acid surface treatment, the recovery rate is only about 30 to 60% of the original, thus greatly increasing the manufacturing cost

It is known that when the content of carbon nanotubes in the polyester substrate is greater than 5% by weight, the dispersion of carbon nanotubes is poor, which will cause the polymer substrate to be easily cracked, brittle and difficult to granulate
