Technical field

The present invention relates to textile fabric technical field more particularly to an a kind of preparation methods for conductive yarn.

Background technique

Conductive fiber can be not only used for electromagnetic wave absorption, eliminate electrostatic, and can electric signal detection and transmission, institute With conductive fiber is achieved extremely successful and is widely applied in terms of the development of intelligent textile.However, current conductive yam Line mainly has metal filament, carbon fiber, conducting polymer yarn, electroconductive polymer coating yarn etc., asks existing for these yarns Topic is that prepare difficulty perhaps expensive or be of limited application, it is difficult to which mass production simultaneously meets market needs.

Summary of the invention

The purpose of the present invention is to provide a kind of preparation methods of electric conductivity yarn.

The present invention provides a kind of preparation method of conductive yarn, the conductive yarn is prepared by the following method:

Step S1, yarn pretreatment: by the solution such as yarn detergent, acetone, ethyl alcohol ultrasonic cleaning and drying first, Or after plasma clean, clot；

Step S2 says that the yarn pre-processed in step S1 is put into the vacuum chamber of vacuum evaporation winding film coating machine and is plated Film:

To vapor deposition vacuum chamber, background vacuum is made to reach 5 × 10-³~5 × 10-4Pa；Set target-substrate distance as 15cm；Crucible used: alumina particles --- alumina ceramic crucible, Argent grain --- tungsten evaporation boat is deposited；Electric current: alumina particles is deposited For 70A~100A, Argent grain is 180A~300A；Using the method for hot evaporation, by metal evaporation to yarn, in the yarn One layer of metallic film of upper formation；

Optionally, the yarn is spun polyester thread, and polyamide fibre yarn, cotton yarn etc. can yarn.

Optionally, the deposition particle is Argent grain, alumina particles and other metals that can be deposited, non-metallic particle. Preferably, in the step S2, by METAL HEATING PROCESS to evaporating temperature, by metallic particles vapor deposition to the yam surface.

The implementation of the embodiments of the present invention has the following beneficial effects: the conductive yarn provided according to the present invention, benefit Continuous metal film is formed on yarn by metal evaporation to yarn with vacuum thermal evaporation technology.It is prepared by the method Yarn has good electric conductivity, and the influence generated to physical properties such as the strengths of yarn is smaller.
