Effect of oxygen plasma pretreatment on PTT shape memory fabric permeability was researched.PTT shape memory fabric was treated by oxygen plasma.PTT fiber surface morphology,chemical structure,PTT fabric air permeability,moisture permeability,strength and elongation were tested before and after oxygen plasma pretreatment.The result shows that after oxygen plasma pretreatment,surface roughness of PTT fiber can be increased,part of radical group property can be changed,surface energy of the fiber can be incre...
