摘要： Porous acrylic and modacrylic fibre having a porosity above 0.3 cm³g⁻¹, an internal surface area of at least 50 m²g⁻¹ (when its decitex is greater than 2.5) or at least 35 m²g⁻¹ (when its decitex is not more than 2.5), and a water imbibition of at least 65% (when its decitex is greater than 2.5) or at least 55% (when its decitex is not more than 2.5) and other porous acrylic and modacrylic fibre can be produced by contacting never-dried, standard wet-spun fibre with a water-miscible organic liquid which is a non-solvent for the fibre and has a boiling point below the glass transition temperature of the fibre to exchange the water in the fibre for the organic liquid, and then drying the fibre so as to remove the organic liquid without collapsing the fibre. Porous fibre made in this way or other porous acrylic or modacrylic fibre in dry or never-dried state can be impregnated with an additive either by immersion in a solution of the additive in an organic liquid of the above type or by immersion in a solution or liquid dispersion of the additive in a different liquid followed by exchange of that liquid with an organic liquid of the above type, followed in either case by drying to remove the liquid. The drying conditions can be controlled to provide uncollapsed fibres, fully collapsed fibres or, preferably, novel partially collapsed fibres, from which the additive is released in a sustained fashion at a rate determined by the degree of collapse of the fibres.

摘要： An electrically conductive material, particularly an electrically conductive fibre, comprises a polymeric material modified by reaction with the reaction product of a mono- or polyfunctional amine with cyanamide, dicyandiamide, guanidine or bisguanidine, or a salt thereof, and impregnated with copper sulphide. The fibre can be produced by a method which comprises
(a) treating a fibre with an aqueous solution of the said reaction product to form a modified fibre; and
(b) treating the modified fibre with an aqueous solution or solutions of a copper salt, a reducing agent and a sulphur-containing compound capable together of forming copper sulphide which is adsorbed onto the modified fibre. The fibre is useful in providing anti-static or static-dissipative properties in textile, paper and other products.摘要翻译： 导电材料，特别是导电纤维，包括通过与单官能或多官能胺与氨基氰，双氰胺，胍或二胍或其盐反应产物并用硫化铜浸渍而改性的聚合材料。 纤维可以通过以下方法制备：（a）用所述反应产物的水溶液处理纤维以形成改性纤维; 和（b）用能够一起形成吸附在改性纤维上的硫化铜的铜盐，还原剂和含硫化合物的水溶液或溶液处理改性纤维。 该纤维可用于在纺织品，纸张和其他产品中提供抗静电或静电消散性能。 C
