The closed porosity of polyacrylonitrile fibres wet-spun from dimethyl acetamide solutions was investigated in raising the spinning bath temperature from 2 to 20°C. The dependence of the porosity of the fibre on the conditions of plasticization treatment is established. The fibre treated in saturated vapor medium has higher porosity values (narrow transmission factors in chlorobenzene) than the fibre treated with a hot aqueous solution of dimethyl acetamide. The dependence of the fibre porosity… CONTINUE READING
