Definitions

• This invention relates to improvements in the restoration of lustre to delustred threads, yarns, fabrics, or other products made of or containing cellulose acetate.
• Cellulose acetate goods can be delustred by treatment in boiling soap baths or in 'acid' baths.
• woolly effects can be produced by a control of the concentration and temperature of the bath and the duration of the treatment, the volume or bulk of the goods being increased to 3 to 5 times their original volume.
• a lustrous cellulose acetate fabric can be converted into a fabric that is both lustreless and more bulky in character.
• solvents or swelling agents may be used I the organic acids (acetic, formic, etc.) employed for delustring purposes, and also alcohols, esters and salt solutions, e. g. a solution of calcium sulphocyanide.
• organic acids acetic, formic, etc.
• alcohols, esters and salt solutions e. g. a solution of calcium sulphocyanide.
• the steaming operation is effected with aid of steam at a pressure in excess of the atmosphere.
• the pressures used may range up to 5 atmospheres absolute or even higher, always provided that the temperature is not so high as to melt or damage the cellulose acetate oods.
• F igured and other partly lustrous and partly lustreless goods of a very attractive character are produced by applying to a delustred fabric a printing paste or a stencilling or like preparation containing a solvent or swelling agent, and afterwards steaming the goods, so that the fabrics are relustred at the parts to which the paste is applied. In this way, brilliant and effective figures may be produced on a dull ground.
• mordants may be added to the relustring astes so that different colour effects can also e obtained.
• Relustring may also be effected by wholly or partiall v immersing the goods, in, or other-- wise treating'the goods with, baths containing a solvent or swelling agent, to which may be added if desired dyestu s, salts, mordants, or protective colloids, separately or in combination. After a suitable interval, the goods are removed, Fuickly dried and sub- ]ected to the action 0 steam.
• baths containing a weak solution of an organic acid are used, but if stronger solutions are used, the steamin operation may be shortened or even omitted,
• the relustring of the delustred parts is accompanied by partial delustring of the lustrous parts, so that goods of a uniform lustre are obtained, this effect being probably due to the fact that the steam used for relustring, though substantially free from water in the form of condense or mist, may, nevertheless, carry traces of water which can act as a delustring agent for the fully lustred portions of the goods until a state of equilibrium is reached.
• steam carrying large quantities of condense or mist that is to say, a mixture of steam and water, were applied to the fabric, it would act as a delustring agent in the same way as boiling water or boiling soap solutions.
• Example I Piece goods of delustred cellulose-acetate are printed with a paste made by emulsifying together 650 grams of gum arabic (50%) with 300 cc. of ethyl alcohol and 15 grams of Rhodulin orange. The printed goods are well dried, steamed at a pressure of 1.4 atmospheres absolute, and finally cold washed. The pattern then comes up as a lustrous figure on a lustreless ground.
• Example I Delustred cellulose acetate yarn in the form of hanks is partly immersed in a bath containing 0.5% of acetic acid, and maintained at a temperature of 50 C. After one-half to one hour, the yarn is removed, centrifuged, dried and steamed for half an hour under pressure. i
