Graft copolymerization of acrylic acid onto wool fibers was carried out using a γ-radiation induced technique. The degree of grafting was influenced by the monomer concentration and the radiation dose. The changes in the polymorphism of the grafted wool fibers were investigated and compared with that of the parent fibers. A further increase in the degree of grafting was found to cause a slight reduction in moisture sorption. Affinity towards basic dye and the mechanical properties of wool fibers were improved by the graft process. 相似文献

The hydrophilicity, dyeing and antistatic ability of polypropylene microfibre (PPMF) wereimproved by plasma-induced vapor grafting with acrylic acid. The effects of plasma discharge time, power,liquid phase acrylic acid temperature and environmental temperatore on grafting yield were investigated. Theexistence of grafted polyacrylic acid (PAA) was verified by ESCA and ATR FT-IR. The morphology ofgrafted PAA was directly observed by SEM. The wicking test shows that the hydrophilicity of modifiedPPMF is greatly enhanced. The dyeability test of modified PPMF was carried out using Dispersion Yellow. Itwas found that the dye uptake ratio is linear to the weight percent of grafting. The antistatic ability wasindicated by specific resistance. The specific resistance of modified PPMF was reduced to 10~6~10~7Ω·cm,thus the antistatic ability was considerably improved. 相似文献
