Abstract
264,529. Keberlein & Co., Akt.-Ges. Jan. 15, 1926, [Convention date]. Yams &c., treating with liquids.-The appearance, strength and other properties of artificial silks made of regenerated cellulose, are modified by treatment throughout with the following swelling-agents :-alkadi hydroxide solutions of 10-25 Be; sulphuric acid of above 43 BÚ strength; phosphoric acid of specific gravity above 50 Be; hydrochloric acid of above 20 BÚ; nitric acid of above 35 BÚ strength; or mixtures of such acids including mixtures of nitric and sulphuric acids; concentrated salt solutions, in particular zinc chloride solution of above 50 BÚ and calcium sulphocyanide solution above 25 BÚ; and copper oxide ammonia solution containing more than 0.3 per cent copper. To the swelling-agent may be added substances that moderate its action, such as mono- and poly-hydric alcohols, heterocyclic bases, formaldehyde or ammonium salts. The treatment is preferably carried out at normal temperature; but temperatures below 0 C. may be employed, while if a salt solution is employed the temperature may be raised up to 100 C. The process is applicable to the treatment of loose, spun, woven or made-up material, and the artificial silk may be alone or mixed with other fibres; it may also be applied to staple fibre. The material may be in the loose condition or under tension. The effect produced depends on the conditions; generally it comprises more or less loss of lustre, a gain in translucency and transparency, a reduction in the stiffness of the material, and an increase in the strength; with a mixture of nitric and sulphuric acids, the product may be non-translucent and lustreless or it may show a soft broken-up lustrous effect resembling crepe-and materials treated in this way are advantageously denitrated. In examples, the silk is treated with soda lye of 20 BÚ strength at normal temperature, or with sulphuric acid of 49 BÚ at - 10 C, or with nitric acid of 40 BÚ at normal temperature, or with a nitrating mixture of 4 parts of sulphuric acid and one part nitric acid, or with zinc chloride of 67 BÚ at 40 C. Specification 215,860, [Class 42 (i), Fabrics, Finishing &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) includes the use of alkali hydroxide solutions of a concentration higher than 25 BÚ. This subject-matter does not appear in the Specification as accepted.
