Title: Improvements in the manufacture of artificial filaments, yarns, films, foils and similar materials
IPC: D06M13/432
Filed: 1936-12-01
Abstract: Filaments, films, and similar materials having a basis of cellulose organic acid esters or ethers, free from halogen and containing substituent radicles containing hydroxy, carboxy and/or unsaturated groups are treated with nitrogen-containing compounds so as to introduce non-acidic nitrogen into the cellulose molecule.  Other radicles besides those containing hydroxy, carboxy, or unsaturated groups may be present in the cellulose derivative molecule and the filaments, films, &c. may be formed by the extrusion or casting of the cellulose derivatives containing hydroxy, carboxy, or unsaturated groups or they may be formed by treating filaments, films, &c. made of regenerated cellulose or cellulose derivatives.  The introduction of nitrogen may be effected by the direct action of ammonia, aliphatic and aromatic amines, alkylolamines, cyclic compounds such as pyridine and cyclohexylamine, acids containing amino or nitrile groups, the salts, esters, anhydrides and acid chlorides of such acids, cyanogen halides, ethylene imine, amides, urea, thio-urea &c. Alternatively, intermediate compounds may be formed.  Thus, materials containing hydroxy or unsaturated groups may first be halogenated and then treated with nitrogen-containing reagents; materials containing unsaturated groups may first be hydrated to introduce a hydroxy group and then treated with nitrogen-containing reagents; materials containing carboxy groups may be treated with ammonia or organic bases and then heated to produce the amide.  The nitrogen-containing products may be after-treated.  Thus amino, hydroxy or carboxy groups may be alkylated, aralkylated etherified, acylated, or esterified, nitrile groups may be converted to amino, amide or carboxy groups, amide groups may be converted to amino groups, and amino groups may be diazotized.  Examples illustrating the invention are given.  It is stated in one of the Provisional Specifications that instead of treating the cellulose derivative materials, in the form of yarns and other formed products, with nitrogen-containing reagents, they may be treated in the form of powder, flake, or granules, or in the fibrous form obtained by the conversion of cotton or other materials into the cellulose derivatives in the presence of a now solvent diluent. Specifications 166,767, 277,721, [both in Class 2 (ii)], 344,480, 394,722, and 447,832 are referred to.
