2 Claims.

This invention relates to an improvement in pile fabrics and has for an object to provide a material of the same general nature as the well known'transparent velvet andwhich, while re- 5 taining the advantages of transparent velvet, ob-

viates allor substantially all of the disadvantages thereof.

Another object consists in providing such a material which is very durable and wear-resisting, and which retains its appearance in spite of all normal vicissitudes of wear.

Another object consists in providing such a material which has a novel and attractive appearance.

Another object consists in providing such a material which may be very economically produced.

A further object consists in providing certain improvements in the form, construction and arrangement of the several parts, and in the materials employed, whereby the above named and other objects may effectively be attained.

A practical embodiment. of the invention is represented in the accompanying drawing, in which Fig. 1 represents an enlarged detail plan view of the fabric material, and

Fig. 2 represents a section taken in the plane of the line II-II of Fig. 1, looking in the direction of the arrows.

A pile fabric commonly known as transparent velvet has become very popular during the past few years, largely because of its unique appearance and charm which arise from its somewhat sheer, transparent and clinging qualities. There has, however, been a general and substantial disadvantage in this material because of its delicacy and susceptibility to injury through ordinary wear and the action of the elements. Transparent velvet is very easily crushed, even by the weight of the wearer, especially when supplemented by the heat of the body and/or of the atmosphere; and it is very readily injured by any form of wetting. A cleaning process is also Very apt to cause it to lose some of its valuable features..

, My improved fabric has the same sheer, transparent and clinging characteristics -as transparent velvet but it firmly resists crushing or matting as Well as the deleterious effect of moistening. The weight of the wearer will not injure it and it will automatically recover from a shower or the like. Furthermore, it may be cleaned without loss of its charming characteristics. Finally, it is durable and wear-resisting to a very high degreer This fabric material may be woven after the manner of most cut pile fabrics, according to which two grounds consisting of warp and weft threads are woven while the pile threads are interwoven and interlaced back and forth between 5 the two grounds. Thereafter the pile threads are cut intermediate the grounds to form two fabric materials with cut pile protruding therefrom.

Referring to the drawing, the ground warp 10 threads are denoted by 1 and the weft threads by 2. The pile threads, here woven as warps, are marked 3. It will be observed that each pile loop goes under two warp threads and over one intermediate warp thread, thereby forming the 15 well known w-weave. The ground threads may be composed of any suitable material, such, for instance, as silk, artificial silk, cotton, linen; and

the pile threads may likewise consist of any desired material although, in this case, I prefer to Q0 use articial silk of the acetate variety.

The important characteristic of the invention lconsists in the fact that the pile threads, of whatever material they are composed, are twisted to an extent beyond the normal or usual twist of threads used in weavingpile fabrics and, more particularly, velvets. For instance, while it is customary to give such threads from four to seven twists or turns per inch, I prefer to use from forty to forty-flve twists or turns per inch. 30 Furthermore, after the fabric has been woven and the pile cut, I do not untwist or brush out the pile tufts but leave them` in their comparatively tightly twisted condition, which gives a resilient surface thatis extremely attractive in appearance and free from all the defects hereinabove noted as being characteristic of transparent velvets. The high or hard twisting of the pile threads serves to increase their diameter so that they are substantially coarser than the ground threads, as clearly shown in the drawing, and this gives added strength to the 'upstanding pile tufts as well as to the fabric in general. 'I'he fact that the tufts are permitted to remain in 5 their twisted condition eliminates the -necessity of certain steps in the manufacturing procedure relating to the finishing of the fabric material, and thereby decreases the cost of production so that this fabric, with all its advantages, is very 50 economical to manufacture.

It will be understood that various changes may be resorted to in the form, construction and arrangement of the several parts and in the materials employed, without departing from the 55 spirit and scope of my invention; and hence I do not intend to be limited tothe details herein shown and described, except as they may be included in the claims, nor do I intend words or specic designation in the claims to exclude equivalents for the elements so designated.

What I claim is:

1. A velvet clothing fabric comprising a cut pile composed of highly twisted cellulose acetate artificial silk thread, the twist being so high as substantially to increase the normal diameter of the thread, and the material being of such characteras to retain said high twist after cutting andlunder normal conditions of wear, exposure and moisture, whereby the fabric has great durability and compressive resistance and resiliency.

2. A velvet clothing'fabric comprising a cut pile composed of highly-twisted artiilcial silk thread of the acetate variety, the twist being so high as substantially to increase'the normal diameter of the thread, said increased diameter being substantially greater than the diameter of the ground threads of the fabric, and the material being of such character as to retain said high twist after cutting and under normal conditions of wear, exposure and moisture, whereby the fabric has great durability and compressive resistance and resiliency.
