WARP PILE FABRIC Filed June 26. 1931 Patented Nov.22, 1932 PATENT OFFICE FRITZ ANDREAE, OF COLOGNE, GERMANY WARP FILE FABRIC Application filed June 26, 1931, Serial No.

The invention relates to a new type of fabric having an uncut pile face consistingof highly twisted continuous filament crepe threads which is particularly suitable for fine silk and artificial silk materials, and possesses substantial advantages over the known types of fabrics.

In the accompanying drawing- Fig. 1 is an end elevation of the backing with loops before they become automatically spiralized, and

Fig. 2 is av sectional view of the fabric with the loops spiralized.

The known fabrics have in particular the defect that they cannot stand pressure, the

pile bending aside at the points where pressure is applied, and not recovering its erect position spontaneously. The fabric consequently assumes an unpleasant appearance,

' which can only be removed, to a certain extent, by steaming or the like.

It has already been proposed to make the cut pile of a fabric from tightly twisted threads, in order to impart a curly effect to the tufts resulting from the cutting of the pile. Such a fabric, however, also exhibits merely a relatively low compression strength,

particularly because the individual tufts soon become completely untwisted during wear,

there being nothing to prevent that occurrence.

According to the invention, the aforesaid defects are remedied. The invention relates to a pile fabric, with uncut twists formed of spiralized loops such as strongly overtwisted filling threadssuch as crepe threads which when looped upon the weft and warp threads or the base, and as the loops are unrestrained they will take the form of upstanding and 0 spiralized or intertwisted looped and uncut tufts, the spiral form of the tufts being self produced and maintained, so that in use the tufts will embody automatic intertwisted and upstanding tufts, in contradistinction to the pile chenille and uncut velvets. As shown in Fig. 2, the individual, uncut loops at, thus 3.0-. quire a cork-screw twist. The advantage of 'this'new type of crepe pile fabric consists primarily in a quite extraordinary increase in 90 compression strength and resistance of the 547,111, and in Germany March 28, 1931.

pile. For example, the new fabric can be rumpled and twisted to any extent, without producing the slightest creasing of the material, which, on being spread out again, is exactly as smooth as before. Moreover, the pile of this new fabric stands perfectly erect. Consequently, the new fabric can be juxtaposed in any convenient manner, when being worked up into clothing and the like, without any necessity for considering'as was previously the casethe life of the pile.

In manufacturing the new fabric, it is advisable to use a strongly overtwisted thread (crepe thread) for making the pile. When the finished fabric is afterwards dyed in the piece, the individual loops a will then automatically twist in spiral or corkscrew form, as shown in Fig. 2. Other methods, however, might also be adopted for producing the new fabric.

The character of crepe thread is well known and, as stated above, the fabric when dyed in the piece will cause the loops to possess certain characteristics. Obviously, this same result will occur when the fabric is moistened as it is when being treated or subjected to the finishing processes.

Furthermore, it may be stated that the crepe threads to which reference has been made may be defined as consisting of fibres of continuous length.

I claim:

1. The method of producing a fabric which consists in simultaneously interweaving with a backing of warp and weft threads, an uncut pile face consisting of highly twisted continuous filament crepe threads passed under and over the weft threads and looped selectively and successively between two weft threads of the backing, inserting a loop supporting element while said crepe threads are being secured in place, and then withdrawing the said loop supporting element, whereupon the said crepe threads twist to form a plurality of loops projecting substantially at right angles to the warp and weftof the fab- I10.

2. A fabric having a crepe-like pile facing, the pile of which is uncut, said pile consisting of loops of highly twisted continuous 2 meneee filament crepe'ynrn interwoven between the wnrp and Weft threads thereof, st 21pprom'mmtely at right angles t0 the warp and Weft and being twisibedl the produce n plurality of resilient spirals.

In testimony whereof, I my sinfnni'eo FRITZ ANDREAF).
