Embodiment 1

[0024] Soak the UHMWPE fiber in a ferric chloride solution with a mass concentration of 20% for 60 minutes, then take it out and place it in a vacuum device containing a pyrrole solution with a purity of 99%, and treat it at a temperature of 25°C and a vacuum of 730mmHg. After 0.5 hours, ultra-high molecular weight polyethylene fibers with improved or improved surface bonding properties can be prepared.

Embodiment 2

[0026] Soak the UHMWPE fiber in a ferric chloride solution with a mass concentration of 30% for 30 minutes, then take it out and place it in a vacuum device containing a pyrrole solution with a purity of 99%, and treat it at a temperature of 55°C and a vacuum of 730mmHg. After 0.5 hours, ultra-high molecular weight polyethylene fibers with improved or improved surface bonding properties can be prepared.

Embodiment 3

[0028] Soak the UHMWPE fiber in a ferric chloride solution with a mass concentration of 30% for 30 minutes, then take it out and place it in a vacuum device containing a pyrrole solution with a purity of 99%, and treat it at a temperature of 55°C and a vacuum of 700mmHg. After 0.5 hours, ultra-high molecular weight polyethylene fibers with improved or improved surface bonding properties can be prepared.

Abstract

The invention relates to an ultrahigh molecular weight polythene fiber surface modifying method, comprising: 1. placing ultrahigh molecular weight polythene fiber in organic iron sulfonate solution to soak for 15-60 min, where the organic iron sulfonate solution is iron trichloride solution with mass concentration of 18-60%, or one of the iron toluenesulfonate solution, ferric tri(dodecanesulfonate), iron 2-acylamido-2-demthyl-1-propanesulfonate, or iron morphine propanesulfonate solution with mass concentration of 5-40%, and the organic iron sulfonate solvent is normal butyl alchohol or water; 2. placing the soaked polythene fiber in vacuum device with vacuum of 650-730mmHg in the proportion of 100-120 ml of intrinsic conducting polymer monomer per kg of fiber to process at 25-85deg.C for 0.5-8 h, and making it, where the intrinsic condcuting polymer monomer is pyrrole or thiophene with purity not lower than 99%. And the method can effectively surface adhesiveness of ultrahigh molecular weight polythene (UHMWPE) fiber and besides, keep the original strength of UHMWPE and the process is simple.

Description

technical field [0001] The invention relates to a fiber surface modification technology, specifically a method for surface modification of ultra-high molecular weight polyethylene fibers aimed at improving the surface bonding performance of ultra-high molecular weight polyethylene fibers. The international patent classification number is proposed to be Int.C1 D01M 15 / 00 (2006.01).
