Abstract
Regenerated cellulose yarn is produced by spinning viscose having a xanthate ratio of at least 50 into a primary sulphuric acid coagulation bath and then through three successive sulphuric acid coagulation baths, the strength of the second bath being not more than half that of the first bath and the strength of the third and fourth baths being not less than that of the preceding one, the conditions being such that the xanthate ratio after the second bath is 20-40, substantially no stretching is effected in the first and second baths, and stretching to more than twice the original length is effected in the third and fourth baths. Each bath contains sodium sulphate and zinc sulphate in addition to sulphuric acid. The second and third baths may be replaced by a single bath provided with a suitably placed godet roller for returning the yarn to the bath. Using a viscose solution having a viscosity of less than 150 poises and containing 3-11% cellulose and 3-13% total alkali, the acid bath strengths may be successively 40-180, 5-30, 10-50 and 30-100 gm./1 of sulphuric acid. If the initial xanthate ratio is 65-75, the primary bath strength is 70-100 gm./1, and the xanthate ratio after the second bath is 30-40; more than 30 permanent crimps per inch may be subsequently produced by conventional means, even with filaments having a denier number of more than 10. Using a viscose solution having a viscosity of more than 150 poises and containing 3-11% cellulose and 3-13% total alkali, the acid bath strengths may be successively less than 60, less than 30, less than 30, and 30-100 gm./1. The viscose solution may contain 0,1-1,0 millimoles of a coagulation modifier per 100 gm. of viscose. Various amines, N-substituted dithiocarbamates, mercaptoamines, N-substituted mercaptodithiocarbamates, glycol mercaptans, and alkoxy-alkanols are specified as coagulation modifiers. Examples specifying coagulant composition and temperature and degree of stretch are given.ALSO:The compressive resilience and crimp recovery from stretch of regenerated cellulose fibres (see Group IV(a)) and articles made therefrom are improved by treating with an aqueous solution of 0.5-4% of an oxy-acid salt of melamine, exposing to formaldehyde vapour in the presence of 10-30% of water and heating at 120 DEG -160 DEG C. until the resulting resin has set. The oxy-acid may be lactic, glycollic, thioglycollic, or gluconic acid. The salt may contain 0.3-3.0 moles of oxy-acid per mole of melamine and 2-5 moles of formaldehyde may be employed per mole of melamine.
