| Abstract: | A method of ultraviolet irradiation gas-phase graft modification was studied for PBT melt-blown fabrics. The modification conditions and the influential factors were discussed. Acrylic acid (AAc) was selected as the grafting monomer according to the experimental results. The effects of the modification conditions, such as irradiating time, preirradiating time, monomer temperature, initiator concentration, nitrogen pressure, on the graft yield and surface wettability tension were discussed. The results showed that the optimal grafting conditions were as followed: room temperature, light distance 20 cm, preirradiating time 10 min, benzophenone 0.037 mol/L, nitrogen flow rate 87.5 L/h, reaction time 30 min. The surface wettability tension was about 85 mN/m after ultraviolet irradiation grafting and was increased with the increase of graft yield. |
