Description

Patented Mar. 15, 1938 UNITED STATES PATENT OFFICE 2,111,449 DELUSTERED RAYON No Drawing. Application March 11, 1933, Serial No. 660,438
2 Claims. (Cl. 28-1) The object of our invention is to produce an improved delustered rayon and to accomplish desired delustering in a novel, satisfactory, economical and convenient manner, without detract- 5 ing appreciably from the desirable qualities of the rayon.
In carrying out our invention, we incorporate into the solution to be spun, to produce the desired delustered or matte effect, chlorinated di- 10 phenyl and an inert organic material.
A description of certain of the commercial chlorinated diphenyls or aroc10rs" is found in the journal of "Industrial and Engineering Chemistry, November, 1930, pages 1180 to 1182 15 inclusive. We prefer to use a finely divided chlorinated diphenyl which is solid at ordinary temperatures.
Examples of the inert organic material which we employ in combination with. the aroclor are petroleum oil, or low melting waxes such as petroleum jelly, paraflin and the like.
These ingredients are added, in amounts as per cent of the finished yarn, of aroclor from .2 to 10% to from .5 to 15% of oil or the like.
The yarn produced according to the present invention has a more pleasing appearance than that obtained with either aroclor or oil alone. It is considerably duller as to luster than if the aroclor were omitted. It is somewhat duller, and has a 30 somewhat richer texture and less metallic appearance, and is also a softer, more pliableyarn than if the oil were not used. Furthermore the tensile properties are much stronger, as the total lustered rayon containing from about 0.2 to 10 per amount of delustrant, at least in the preferred example given, is less by nearly half of that required with oil alone.
A specific example is as follows:
Viscose is prepared in the normal way and to the solution we add .075 per cent by weight aroclor and .20 per cent by weight mineral oil, this oil containing a small amount of a suitable emulsifying medium, for example sperm oil. The viscose that is conventionally used in making 10 rayon contains approximately 7.3% cellulose and the proportions of aroclor and oil may be expressed in terms of the weight of dry yarn as approximately 1.0% by weight aroclor and approximately 2.5% by weight mineral oil. The 15 spinning of this viscose solution takes place in the normal manner and the yarn so produced is processed and dried by the normal procedures.
