摘要

In this paper, the waterborne polyurethane (WPU) coating was prepared using polyaddition reaction of polymethylene glycol, 2,2-bis(hydroxymethyl) propionic acid, and hexamethylene diisocyanate. The polyamide 11 (PA11) and PA11anodiamond (ND) fibers were prepared using simple method. The dip-coating technique was used to coat the fibers with WPU. The fractured surface of WPU coated fiber containing ND was smooth according to scanning electron microscopic images; however the morphology of the fibers with out nanodiamond was less smooth and adjoined at various places. The effect of pressure on the adhesive strength of WPU adhesive containing fibers with various ND content was also studied. The adhesive strength was continuously increased with the increase of pressure till 25 kg f/cm2 and also with nanodiamond loading. The water absorbing tendency of WPU coated polyamide fibers enhanced from 5.4-7.8 % with filler loading.
