Description

Patented Mar. 17, 1931 UNITED STATES PATENT OFFICE DINSHAW RATTONJI NANJI, OF LONDON, ENGLAND, ASSIGNOR F ONE-HALF TO DUNCAN MAYBUBY STEWART, OF LONDON, ENGLAND PROCESS FOR THE MANUFACTURE OF TEXTILE YARNS No Drawing. Application. filed September 13, 1928, Serial No. 305,868, and in Great Britain July 20, 1928.
The present invention relates to a new or improved process for the manufacture of textile yarns of the type wherein synthetically produced fibres are combined with natural bast fibres.
The object of the invention is to produce a yarn, having the visible and tangible characteristics of artificial silk, from synthetically produced fibres and natural vegetable 0 bast fibres, wherein the fibres may be blended and spun on the machines commonly employed in the industry in a manner more fully set forth in the sequel. It has been found essential for this purpose that the bast fibres employed should have an ultimate fibrile or filament length of 2 inches or more, such as is the case with fibres obtained from plants of the genus Boehmeria; and it is proposed therefore to combine or blend certain of the artificial silk fibres or similar synthetically produced fibres, lustrous or otherwise (such as a viscose, cellulose acetate, cuprammonium or chardonnet) in the form of waste of suitably cut lengths with natural bast fibres the ultimate fibriles of which have a length of 2% inches or over. The blending is carried out after the vegetable fibres have been resolved into their ultimate fibriles. For it has been found from practical tests that only after the bust fibres have been resolved into their ultimate fibriles or filaments, before blending with the artificial silk fibres, can the blend be satisfactorily worked up into yarn. The vegetable fibres are re solved by any of the known methods such as by use of acid or alkaline and bleaching agents.
The combed bast fibre is then blended in any desired proportion with any of the artificial silk fibres above mentioned in the form of a sliver or a top, the blending being carried out in the usual way and the blend recombed if necessary.
Alternatively the b ast fibre before or after resolution may be blended with the artificial silk fibre or any similar synthetically produced fibre and the mixture opened by carding or garnetting.
The mixed combed top thus produced is then spun on any suitable spinning machines preferably on a cap or a ring spinning frame. Owing to the superior strength of their bast fibre component the yarns thus produced have extremely satisfactory durability and both dry and wet strength.
I claim I 1. A process for the manufacture of textile yarns, consisting in resolving natural bast fibres embodying ultimate filaments of a length of at least two and one-half inches into such ultimate filaments, blending the ultimate filaments with synthetically produced fibres, and then spinning the blend.
2. A process for the manufacture of textile yarns, consisting in resolving natural bast fibres embodying ultimate filaments of a length of at least two and one-half inches into such ultimate filaments, opening the filaments out and combing them, blending the combed, ultimate filaments with synthetically produced fibres, and then spinning the blend.
3. A process for the manufacture of textlle yarns, consisting in resolving natural bast fibres embodying ultimate filaments of a length of at least two and one-half inches into such ultimate filaments, opening the filaments out and combing them, blending the combed ultimate filaments with synthetically produced fibres, combing the blend, and then spinning the blended, combed tops so produced.
In testimony whereof I afiix my signature.
DINSHAW RATTONJI NANJI.
