Dispersing the carbon nanotubes as conductive agent to the thermoplastic high molecule to form the core material; making the non-conductive fiber material as surface material and compositely spinning with the two materials to get the center-eccentric type cross section, and then make the electro-conductive fiber whose electro-conductivity is excellent in the thermal stretch working procedure.
Description
Technical field
The present invention relates to a kind of manufacture method of conductivity type composite fibre.
Background technology
In general, one of shortcoming of chemical fibre such as polyamide fiber and polyethylene terephthalate (PET) fiber is charged because of static easily.In order to overcome this shortcoming, can allow synthetic fiber possess electric conductivity.Wherein relatively typical method exactly with CNT as conductive agent be distributed to form core on the thermal plastic high polymer and non-conductive fibrous material as the skin material, both are carried out composite spinning and make the electric conductivity conductive fiber.The CNT diameter is 10~100nm, and length is about 1~40 μ m, and dispersion amount reaches 5~25 weight % usually.After being distributed to CNT in the condensate, owing to CNT is in contact with one another or very makes this condensate have electric conductivity near tunnel (Tunnel) effect that causes.For CNT being in contact with one another or very approaching, need make the dispersion concentration of CNT reach quite high degree.
On the other hand, conductive composite fibre can make product have antistatic performance after being applied to fiber products such as carpet and dust-free clothes, and is therefore, very extensive as the antistatic material range of application.In order to prevent that computer from breaking down because of static, the electric conductivity that the carpet requirement in the computer room has higher level.At present, mainly adopt conductive layer to be exposed to fiber (the clear 57-25647 of Japanese publication communique) or the back processing conductive fiber that behind fiber surface covering conductive materials, processes or the metal fibre etc. of fiber surface in high conductive fiber field.
But conductive layer is exposed to the synthetic fiber of whole fiber surface, and carbon dust will come off and reduce the operation percent of pass by the precursor from move in throwing and following process stage.In addition, the surface conductance material of back processing type conductive fiber also is easier to come off, and fibrillation (Fibrillation) problem then in use appears in metal fibre.In a word, the practicality of prior art is in-problem.
Summary of the invention
The object of the present invention is to provide a kind of shortcoming that had not both had above-mentioned high conductive fiber, throwing is good again, prevents the manufacture method that comes off and reduce electric conductivity and do not have the high electroconductive synthetic fibre of silk quality defectives such as fibrillation because of conductive materials.That is to say, CNT is distributed to as conductive agent forms core on the thermal plastic high polymer; Non-conductive fibrous material carried out composite spinning as the skin material to both and obtain the high conduction conductive fiber in eccentric type cross section.
The manufacture method of the high electroconductive synthetic fibre of the present invention comprises following operation: (1) is distributed to material preparatory process on the thermal plastic high polymer to CNT with 5~25 weight %; (2) be core with the material that obtains in the above-mentioned material preparatory process, non-conducting material carried out the spinning process of composite spinning operation as the skin material.
That is to say, the present invention relates to a kind of manufacture method of composite conducting fiber of excellent electric conductivity.CNT is distributed to as conductive agent forms core on the thermal plastic high polymer; Non-conductive fibrous material is carried out composite spinning and obtains the eccentric type cross section both as the skin material, make the conductive fiber of excellent electric conductivity then by the hot-stretch operation.
The CNT diameter is 10~100nm, and length is about 1~40 μ m, and dispersion amount reaches 5~25 weight % usually.Performance and cost performance during with 7~15 weight % are best.After being distributed to CNT in the condensate, owing to CNT is in contact with one another or very makes this condensate have electric conductivity near tunnel (Tunnel) effect that causes.For CNT being in contact with one another or very approaching, need make the dispersion concentration of CNT reach quite high degree.
When the dispersion amount of CNT is lower than 7 weight %, can not obtain satisfied electric conductivity; When dispersion amount was higher than 25 weight %, though electric conductivity is fine, expense was very high, and the even dispersion of CNT simultaneously also can become a difficult problem.In addition, when length of carbon nanotube less than 1 μ m of the present invention, can't reach satisfied tunnel effect and reduce electric conductivity; When surpassing 40 μ m, then can influence the machinability (Processibility) of technology for making tobacco threds.In addition, containing the compositely proportional of the core of CNT and general macromolecule skin material should be at (core: the skin material) in 5: 95 to 20: 80 the scope.Compositely proportional is lower than at 5: 95 o'clock, will can not satisfy the conduction requirement because of electric conductivity reduces, and has surpassed at 20: 80 o'clock, then can defective products occur in spinning process, has increased the difficulty when making fiber.As shown in Figure 1, composite conducting fiber of the present invention is made up of skin material and core, and the skin material is a non-conducting material, and core is then for to comprise CNT at interior conductive material.
