ONG FUI? SHORT/CUI? .CETHTE INVENTOR y @4f/@iwal ATTORNEYS lnatentedzli'eb. 18,- 1947 YARN" Austin N. Oppenheim. New York, N. Y., mimm-V to Unique Fibers, Inc., New York, N. Y., a oorporation of New York Appucauon Much 12,1946, sensiNo. 653,965 l This invention relates to yarns made of a, mixture or blend. of fibres -of different kinds and is concerned more particularly with a novel yarn which may be employed in the production of fabrics of unusual and attractive appearance and remarkable softness in hand 'and drape. The new yarn can bef'produced at relatively lowcost for preparing and spinning operations and may be used inthe manufacture of woven and knitted fabrics without changes in the machines or methods ordinarily employed.

The yarn of the invention includes a substantial proportion of animal fur, which may be either the fur or hair ,of animals, or a mixture of both fur and hair. Preferably, .theyarn includes a mixture of furs of different characteristics, so

' that the fur content of the yarn may give softness, lustre, springiness, novel surface effects,

etc., to fabrics made of the yarn. In addition, the yarnincludes a mixture of synthetic fibres, which act as a carrier, provide body, give theyarn soft ness and smoothness, and also bind in the fur fibres. AIn my co-pending application, Seria1 No. 558,- 1.64,5 mea october '12, 1944, I disclosed a yam spun from a .blended mixture of synthetic fibres, wool, and fur, and pointed out that the wool performed the function of binding in the other-` flbres and strengthening the yarn and also that the wool content gave fullness, spring, and resilience to fabrics made of the yarn. While the yarn of the co-pending application has proven highly satisfactory for many purposes, instances occur in which the presence of the wool is ob jectionable, because of the particular use to'k which fabrics made `of the yarn are to be put. In myA further experiments with the prior yarn, I have found that a yarn similar in its general char.

found to serve many lof the useful purposes served by the wool in the prior yarn, particularly the binding' function, and the new yarn may, accordingly, be employed in the production of various fabrics in which the. presence `of the fur content is desired but the use of wool is to be avoided.'

In making they new `various kinds and find that mink, muskrat, wolf, squirrel, fox, beaver, ermine, nutria, opossum,

sable, seal, and raccoon are most desirable. These furs differ widely in their physical characteristics and, for that reason, I prefer to use combinations of two or more different kinds of fur to obtain novel effects. For example, mink and muskrat fur may be used to advantage, `because mink is -amounts varying from about 10%. to about 65%,

acteristics to the prior yarn and entirely satisfactory in respect to wearing qualities and freedom from shedding ofthe fur fibres used, may be made by a proper selection of the constituents of the synthetic fibre content of the blended mixture to be spun. Y

The single gure 4of the drawing is a view in perspective of one form of the new yarn.

In the new yam, I employ with the fur a soft and. lustrous and gives desirable surface effects while muskrat imparts spring to the fabric. Another combination that may be used consists of opossumlwhichV is a relatively long soft fur, and muskrat. Other desirable combinations are wolf and muskrat. fox, squirrel, and muskrat. and fox. and muskrat. In general, it may be said that the short furs mainly provide characteristics I' of handle, drape, etc.. to fabrics made of the yarn,

while the longfurs primarily give surface effectsand provide coverage.

The blend of fibres of which the new yarn spun is composed of vfibres of synthetic materials.

exclusive ofA organic derivatives of cellulose, in

amounts varying from about 10% to about 85%.

fibres of .organic derivatives of cellulose in andfurin amounts varying from about 10% to 50%. Al specific example of the new yarn that is satisfactory for many purposes consists essentially of about 60% viscose rayon fibres, about 20% "cellulose acetate fibres, and about 20%` fur, while another form of the new yyarn consists essentially of about 50% viscose rayon fibres', about 25% cellulose acetate fibres, and ,about .20% fur. In these particular yarnsthe'fur content preferably includes two or more different kinds of fur,

mixture of synthetic fibres, which may include any of such fibres exclusive of those of organic derivatives of cellulose, that are commonly employed in yarn manufacture, vtogether with a substantial proportion of fibres made of organic derivatives of cellulose. Whensuch a mixture of synthetic fibres is mixed with fur and spun, the fibres of the `organic derivatives of cellulose are v proportions may be made in order to meet ecothe kinds of fur being selected inwview of the characteristics which the yarn is to have and the nature and intended use of the` fabrics into which itis to be woven or knitted.

` The 'proportions of the constituent bres of I I the yarn will vary in accordance withl the characteristics, suh as drape. hand, richness,sofi;-` ness, and appearance, thatfthe fabricsl made therefrom -are to have. Also,` variations in the nomic conditions.

The example of new yarn illustrated in the yarn, I -use animal fur of i -aaiaaoo drawing contains libres of rayon. for example,- viscose rayon, acetate fibres. .relatively short i'ur fibres, such as mink, and longer fur libres, such as muskrat,

i In the production' of the new yarn. the blended mixture of the' constituents is preferably spun on derivatives of cellulose, in an'anount varying from about 10% to about 80%. flbresof organicderivatives of cellulose in an amount varying the cotton system, because of the lower cost and A greater ease of. manufacture, and the staple lengths of the synthetic bres used will be chosen with that end in view. Many of the fur fibres are naturally of a staple length which permits them to be handled on the cotton system, but,

for that purpose, theilbres may be readily shortened. It is to be understood that the new yarn j can also be produced on the woolensystem, in which event, fibres of llonger staple length may be employed, although the cost ot production of the yarn is likely to be increased.

The new yarn may be made as either a singles yarn or vas "a plied yarn. `It will vary in count according toI the type of fabric in which it is to be used and the twist will vary in the same way and also in accordance with lwhether it is to bel used in weaving or knitting operations.
