8 Claims.

This invention relates to fabrics in which are used yarns of cellulose acetate and of mohair or other animal fibre, particularly of natural hair or wool. I y

It has long been known that animal fibres. andparticularly natural hair and wool have a spring or elasticity that is lacking in vegetable fibres such as cotton. and filaments made from cotton derivatives, such as viscose or cellulose acetate. This tends to render fabrics wrinkle resistant. Natural fibres both of animal and vegetable origin, such as wool, mohair and cotton, as 'well as such artificial filaments as viscose, have also high water absorption and swell and shrink under moisture and drying, the shrinkage of the rough fibres, such as wool or. mohair, being particularly pronounced, because the fibres mat together to such an extent that the natural resilience of the fibre cannot again separate them.

Cellulose acetate, however, being highly water resistant, does not swell or shrink appreciably because of wetting and drying. Moreover it does not irritate the body of the wearer as do some woolen clothes. l This invention relates to a fabric in which the advantages of bothtypes of yarn are obtained and the disadvantages minimized and comprises the use as warp of yarn solely or predominantly of cellulose acetate and as woof or filling of a yarn containing both cellulose acetate and mohair or other animal fibre. body and resilience to the fabric, and the cellulose acetate counteracts the shrinking of the wool. The fabric is non-irritant and of pleasing appearance. Reference will be made to the drawing, the Single figure of which shows in a conventional or I diagrammatic manner a fabric involving my invention. I

Certain threads, which may be warp threads, are indicated at l and the others, which may be the filling or woof threads, at 2. While a perfectly plain weave, is shown, it is to be understood that any type or design may be used. These warp threads are preferably of cellulose acetate only and may be continuous or spun threads.-

One type .of yarn which may be used for the warp is made in the following manner. The filaments are extruded and twisted in the usual manner toform a coherent thread or yarn. This is preferably crimped and then abraded to such an extent that some of the outer filaments are broken, usually from 30 to 35 per cent of the filaments, although more or less may be. This causes the threads to have a fuzzy or woolly sur- The animal fibre gives face, especially if they have been crimped. A fabric containing such yarn and also yarn containing wool, angora, merino, cashmere, camels hair, mohair or the like, has great covering power and body.

It is to be understood thatother forms of cellulose acetate yarn may be used, and that these may be spun or be continuous or be twisted from two-or more strands, but in any event this thread will be predominantly of cellulose acetate.

The filling threads 2, on the other hand, are strands of cellulose acetate and of mohair or other animal fibre intertwisted. By varying the denier of the strandsor by using more than two. strands, the proportion of one type to the other may be varied, but there should be at least twenty-five percent of each, and I prefer the mohair, to make up from 50 to of the thread. The acetate strand may be of the fuzzy type already described and may be pigmented if desired. These strands are, as is usual, separately twisted and then twisted together so as to givev a balanced twist.

The filling thread may be spun from fibres of mohair and cellulose acetate in suitable proportion, the amounts of which are of the same order, and here also the acetate may be pigmented black or white or in colors.

The resulting fabric, besides having a pleasing distinctive appearance and feel, is non-irritant, holds its shape well when pressed with heat and moisture as in tailoring but does not retain incidental creasing due to folding or mussing. This 7 is due to the'inherent resiliency of the mohair. At the-same time, it has a striking advantage in the uniform slight amount of shrinkage which it has in both directions.

The amount of cellulose acetate in the comby thestrand has a fuzzy surface.

2. A fabric consisting of warp and woof threads, the threads extending in one direction being composed predominantly of cellulose acetate and the threads extending in the other direction being composed of intertwisted cellulose acetate filaments and natural animal fibres selected from the group consisting of hair and. wool.

3. A fabric consisting of warp and woof threads, the threads extending in one direction being composed predominantly of cellulose acetate and the threads extending in the other direction being composed of intertwisted cellulose ace-- tate filaments and natural animal fibres selected from' the group consisting of hair and wool, the cellulose acetate filaments and the animal fibres each constituting at least 25% of the threads extending in the second direction.

4. A fabric consisting of warp and woof threads, the threads extending in one direction being composed predominantly of cellulose acetate and the threads extending in the other direction being composed of intertwisted cellulose ace tate filaments and wool fibres.

5. A fabric consisting of warp and woof threads, the threads extending in one direction being composed predominantly of cellulose acetate and the threads extending in the other direction being composed of intertwisted cellulose acetate filaments and mohair fibres.

6. A fabric consisting of warp and woof threads, the threads extending in one direction being predominantly of cellulose acetate and the threads extending in the other direction being twisted from at least two strands, one strand being of cellulose acetate filaments and the other strand being of animal fibres selected from' the group consisting of hair and wool.

7. A fabric consisting of warp and woof threads, the threads extending in one direction being predominantly of cellulose acetate and the threads extending in the other direction being twisted from at least two strands, one strand being of cellulose'acetate filaments and the other strand of wool fibres.

8. A fabric consisting of warp and wool threads, the threads extending in one direction being predominantly of cellulose acetate and the threads extending in the other direction being twisted from at least two strands, one strand being of cellulose acetate filaments and the other strand of mohair fibres,
