Definitions

• the present invention consists of new orna 1 mental threads, cords and knitted, woven or other fabrics comprising both cellulose Bee'- tate yarns or threads which have been wholly or partially delustred by hot aqueous media and normal lustrous cellulose acetate yarns or threads.
• the new mixed threads may be doubled to produce cords, for example for knitting, or may be woven or knitted directly into new fabrics orgarments presenting a unique appearance due to the difference in v lustre, the eifects being enhanced by subsequent dyein as. hereinafter explained.
• t e new fabrics may be knitted or woven from unmixed threads, though of course both types of thread the delustred and the normal lustrous, must be incorporated to produce the new fabrics.
• any desired pattern eifect may be produced due to the difference in lustre and, even in the white," unique effects are obtainable, and the fabrics are eminently suitable for all purposes to which figured silk fabrics have in the past been applied.
• the new fabrics admit of cross-dyeing and are superior to known mixed fabrics, for example of cellulose ace- 40 tate silk and cotton, in a number of important properties, the chief of-wh1ch are feel and flexibility, Supe-rior feel or handle possesses obvlom' advantages, while the greater flexibility particularly noticeable in .45 the new fabrics which have been loosely woven, ofiers the same advantages to the wearer of articles made therefrom which have made knitted fabrics so popular in recent years.
• a convenient method of producing umformly delustred yarn from the normal lustrous yarn consists in the treatment of the latter on cop tubes, bobbins or the like, with wet steam at 100 C., the duration of the treatment being dependent on the degree of delustration required. 'However, it is to be understood of course that the invention is not limited to this method and that any suitable method of delustring may be employed.
• the new mixed goods may be'dyed to produce broadly three different eifects, viz,
• the goods may first be dyed with the insoluble colour to produce a substantially solid shade over the whole, and then (1 ed with a dyestufi' such as Capri blue, whic is absorbed muchmore readily by the lustrous portion.
• a dyestufi' such as Capri blue
• the new goods may also be printed in one, two or more colours, using either or both types of dyestuif above described according to the design required.

• a boiling soap solution is poured on to 1 P kilogramof S. R; A. orange II standard paste whilst stirring.

• the goods are entered and the temperature raised during hour to 708 0 C. and dyeingcontinued for a further hour.
• the goods are then removed, rinsed in water at about C. and dried or otherwisefinished as desired.
• Example 2. To dye 10 kilograms of the mixed cellulose acetate fabric in differential shades of blue.
• a dyebath of 300 litres is made up in the usual. manner with 0.2% of Capri blue reckoned on the weight of the goods and 1 cubic centimetre per litre of glacial acetic acid. p The goods are entered at about 0., the temperature raised gradually to 80 C. and
• the fabric is first dyed with Capri blue as in Example 2, lifted, rinsed and entered at about 40 G. into a dyebath made up as Example 1 but using S. R. A. heliotrope I standard paste instead of S. R. A. orange II. 'The temperature is raised to about 80 C. during hour and dyeing continued for a further hour. The goods are lifted, rinsed and dried.
