Abstract

Fibres of cellulose acetate having a combined acetic acid content of 40-62 per cent by weight are obtained by impregnating cellulosic fibres with an acetylation catalyst from an aqueous solution of the catalyst, treating the impregnated fibres with acetic acid vapour at a temperature of 100-130 DEG C. in order substantially to replace the water in the fibres, and subsequently treating the fibres with acetic anhydride vapour at a temperature of 100-140 DEG C. Before being treated with the acetic acid vapour, the impregnated fibres may be partially dried in order to reduce the amount of water to be removed by the acetic acid. The cellulosic fibres may be in the form of loose fibres or in the form of yarns or fabrics. Viscose staple rayon having a permanent crimp may be subjected to the treatment, and the resulting cellulose acetate fibres retain the crimp. The process is preferably carried out with the cellulosic fibres advancing continuously through each successive step. The acetylation catalyst may be a salt, e.g. sodium, potassium, or lithium acetate; di- or tri-sodium or ammonium phosphate; zinc, copper, aluminium, stannous, or stannic, chloride; copper, zinc, or aluminium sulphate or alum; or ammonium oxalate. The treatment with acetic anhydride vapour is continued for at least 3 hours, prererably 4-7 hours. The supply of acetic anhydride vapour to the treatment chamber is preferably renewed continuously. Dyed cellulosic fibres such as viscose staple fibres may be subjected to the acetylation without change in the colour or shade.
