| titleOfInvention | Weighting filaments of synthetic linear polyamides |
| abstract | 547,039. Treating textiles with liquids ; dyeing processes. BRITISH CELANESE, Ltd. Feb. 7, 1941, No. 1643. Convention date, Feb. 7, 1940. [Class 15 (ii)] Textile material comprising filaments of synthetic linear polyamides are impregnated with a solution of a weighting metal compound and the weighting metal is then fixed on the material as an insoluble compound. The synthetic linear polyamide may be one made by condensing a diamine with a dicarboxylic acid or one obtained by self-condensation of an amino acid. It may be obtained from tetra-, penta-, or hexa-methylene - diamine and adipic, suberic, or sebacic acid, or from octa-, or decamethylene - diamine and adipic or p-phenylene di-acetic acid, or from 4 : 4<SP>1</SP>-di(aminomethyl)- benzene and sebacic acid. It may be obtained from 6 - amino - caproic acid or 9 - amino - nonanoic acid. The filaments obtained from these polymers may be subjected to stretching treatment. Weighting may be effected by treatment with solutions of salts of tin, lead, titanium, zinc, antimony, aluminium, bismuth, or tungsten. Impregnation may be effected at raised temperature and in the presence of swelling agents, e.g. formic acid. The fixing treatment may be carried out by subjecting the impregnated material to a hydrolytic treatment for the weighting metal compound and then treating with a solution of a substance capable of forming an insoluble compound of the weighting metal. Stannic chloride may be hydrolysed by washing. Disodium hydrogen phosphate may be used as fixing agent. It is preferred to treat also with a second fixing agent such as sodium or potassium silicate. Yarns, staple fibre, or fabrics may be treated. The treatment may be performed on the tensioned or untensioned materials which may be travelling continuously through the baths. The textile material may contain, besides the polyamide filaments, filaments of cellulose acetate or other cellulose ester or ether, regenerated cellulose, silk, cotton, or wool. The weighting treatment may also subdue the lustre, and increase the affinity for silk, wool, and direct cotton dyes. It gives the material a fuller and silkier handle, raises the melting point, and increases the elongation in both dry and wet state. |
