| titleOfInvention | Improvements relating to the manufacture of filaments and like materials from artificial resins |
| abstract | Filaments, fibres, foils, films and all extruded articles having a basis of artificial resins free from nitrogen and capable of being dyed with aqueous solutions of dyestuffs comprise the incorporation therein before, during or after formation of the article of not less than 3 per cent of one or more polymers or copolymers obtained from at least one ester of general formula CH2=CR1-COOR2NR3R4 where R1 may be hydrogen or a hydrocarbon residue, R2 an alkylene or arylene radicle, R3 and R4 hydrogen or 1 or 2 hydrocarbon residues which may be hydroxylated or joined with one another by lateral linkage or by ring formation with or without a hetero atom. Suitable nitrogen-free polymers are the polymers and copolymers of vinyl chloride (including those chlorinated after polymerization) and vinyl acetate, styrene, butadiene and esters of acrylic acid and its derivatives. The esters which may be incorporated include the acrylates and methacrylates of dimethyl-, diethyl- and dibutyl-amino-ethanol, mono-, di- and tri-ethanolamines, hydroxyethylmorpholine, hydroxyethylpiperidine and of diethylaminocyclohexyl alcohol. The incorporation can take place before, during or after the formation or shaping of the article for example, by kneading in a kneading-trough, by solution of the materials in a common solvent, by grinding to a powder a mixture of the nitrogen-free resin and the polyester, by incorporation of the monomeric ester and its polymerization "in situ," or by treatment of the finished article in a swelling solution of the nitrogenous polyester. Drying may be carried out by any known method. In an example, 350 parts by weight of a spinning solution of 30 per cent by weight of polyvinyl chloride and 70 per cent by weight of a mixture of equal volumes of carbon disulphide and acetone is mixed with 10 parts by weight of a 50 per cent solution of the poly-methacrylate of dimethylamino-ethanol. The mass is kneaded and formed into threads, which are dyed an intense blue by the dyestuff, No. 828 in the Dyestuff Tables of Schultz (7th edition), the bath being acidified with 1 g./litre formic acid. A similar thread, but without the polyester remains completely uncoloured in the same conditions.ALSO:Filaments, fibres, foils, films and all extruded articles having a basis of artificial resins free from nitrogen and capable of being dyed with aqueous solutions of dyestuffs comprise the incorporation therein before, during or after formation of the article of not less than 3 per cent of one or more polymers or copolymers obtained from at least one ester of general formula <FORM:0602191/IV (c)/1> where R1 may be hydrogen or a hydrocarbon residue, R2 an alkylene or arylene radicle, R3 and R4 hydrogen or 1 or 2 hydrocarbon residues which may be hydroxylated or joined with one another by lateral linkage or by ring formation with or without a hetero atom.
