Title:
METHOD FOR MANUFACTURING POLYPROPYLENE FIBER CONDUCTIVE WIRE
Document Type and Number:
WIPO Patent Application WO/2017/197903
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a polypropylene fiber conductive wire. One end of a produced hollow polypropylene fiber is fixed on a gas discharge valve of a sealed coating chamber, and the other end thereof is sealedly fixed on a gas suction valve of another vacuum chamber. The coating chamber is connected to a helium source; by means of DC sputtering coating operation procedures, when the degree of vacuum reaches 4-5x10-3Pa, a sputtering pressure value of 3.8x10-1Pa is set on a pressure controller to operate; the helium source and a flowmeter for gas flow are opened, the flow value is adjusted, the gas discharge valve is opened to allow sputtered copper atoms or copper ions to pass through the gas discharge valve along with the helium, so as to enter the hollow polypropylene fiber. The copper atoms or copper ions accumulate in the hollow polypropylene fiber to form a coating layer, which in turn forms a conductor. Polypropylene fiber wires prepared by using the present invention can play a great role in the fields of mobile phone and intelligent wearable devices and the like which have a requirement for small sizes and light weights; the present invention is a conductive material with a wide range of applications.
