ATTORNEY United States Patent 3,006,383 PILE CARPET Levon Mahmarian, 304 24th St., Union City, NJ. Filed Sept. 11, 1959, Ser. No. 839,508 7 Claims. (Cl. 139406) This invention relates to loop pile floor covering and has for an object to provide a pile fabric of the above type having novel and improved characteristics.

Another object is to provide a loop pile fabric in which the loops have added resilience and resistance to crushing.

Another object is to provide a fabric of the above type in which the pile coverage is increased over that usually obtained by the same pile weight and density.

Another object is to provide a loop pile fabric of the above type in which the loops are highly resistant to permanent deformation.

Other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

The nature of the invention will be better understood from the following description, taken in connection with the accompanying drawing in which a specific embodiment has been shown for purposes of illustration.

In the drawing:

FIG. 1 is a warpwise section through a loop pile fabric embodying the invention;

FIG. 2 is a fillerwise section taken on the line 22 of FIG. 1;

FIG. 3 is a partial warpwise section similar to FIG. 1 illustrating a further embodiment of the invention; and

FIG. 4 is a broken elevation illustrating a wrapped filler yarn.

Referring to the drawing more in detail the invention is shown as applied to a loop pile fabric of the usual type woven over transverse pile wires. The fabric comprises a plurality of filler shots 10, bound by chain warps 11 to form a backing. Pile yarns 12 are bound under selected filler yarns and form upstanding loops 14 therebetween, such loops 14 forming the pile surface of the fabric. A fabric of the above construction may be 'WOVBH on a standard velvet carpet loom. The invention is equally applicable however to loop pile fabrics woven on a lacquard loom or on a leno-type stationary wire loom or to tufted or knitted fabrics having similar pile loops. A specific embodiment has been shown for purposes of illustration only.

In accordance with this invention a fillerwise yarn 15 is laid through each fillerwise row of pile loops 14. This yarn 15 is composed of a soft resilient and flexible material such as natural or synthetic rubber or a rubber-like material such as synthetic foam rubber or sponge rubber,

for example polyurethane or Curon, a product of (hirtiss- Wright Corporation.

In the form shown in FIGS. 1 and 2 yarn 15 is elongated in cross section in the vertical direction so as to conform in general to the shape of the loops. The yarn 15, however, may be round in section or of any other convenient shape.

FIG. 4 illustrates a yarn 15a of this character which is round in section and is provided with a core yarn 16 of cotton or the like and with a wrapping 17 which may also be of cotton or the like. Either the core 16 or the wrapping 17 may of course be used independently in order to control the fillerwise yarn 15 and limit the stretch.

As shown in FIG. 3 the fillerwise yarn 18 is round in section and is composed of a spun yarn such as wool or Dacron. The weave in FIG. 3 is otherwise similar to that of FIG. 1 and the various elements have been given the same reference characters.

The

filler yarn

15 or 18 may be of a size to nearly fi=ll the interior of the pile loops 14 while leaving a substan- 3,006,383 Patented Oct. 31., 1961 tial clearance between the filler yarn and the upper part of the loops 14.

When a fabric of the above type is used as a floor covering the resilience of the

yarn

15 or 18 gives the pile surface a soft springy feel and any deformation of the pile loops caused by Walking or furniture is immediately restored when the compressing force is removed. Each loop is thus supported by the filler yarn and by the adjacent loops. Hence the loop has an increased covering power and other characteristics of a carpet having a greater pile density.

Due to this added support the pile yarns 12 may be made of a soft yarn such as Wool or a synthetic material in continuous filament or spun staple form of a character which would normally possess insufli'cient stiffness for loop pile purposes. The entire fabric including the pile yarns and the filler yarns 18 may be made of a material such as sisal, jute or hemp, the filler yarns providing the resilience which is required for loop pile fabric.

Although a specific example has been shown and described it is to be understood that various changes and modifications may be made therein and the invention may be applied to various uses as will be apparent to a person skilled in the What is claimed is:

l. A loop pile floor covering comprising a backing and pile loops bound therein and extending upwardly above the surface thereof, said loops being disposed in aligned rows, and a fillerwise yarn of a soft resilient material extending through the loops of a row, said fillerwise yarns being disposed above said backing and being of a size to fill a portion only of the area of said loops and being adapted to hold said loops at least partially distended above the surface of said backing, the upper part of said loops normally extending above and being spaced from said fillerwise yarns to permit said loops to be at least partially compressed before being brought into engagement with said fillerwise yarns, said loops normally when in extended position enclosing and shielding said fillerwise yarns from view and forming substantially the entire exposed surface of said floor covering.

2. A loop pile floor covering comprising a woven backing composed of filler yarns and warp yarns, pile loops bound under said filler yarns, said loops extending above said backing and being disposed in aligned fillerwise rows, and additional fillerwise yarns of soft resilient material extending through the aligned loops of said rows, said fillerwise yarns being disposed above said backing and being of a size to fill a portion only of the area of said loops and being adapted to hold said loops at least partially distended above the surface of said backing, the upper part of said loops normally extending above and being spaced from said fillerwise yarns to permit said loops to be at least partially compressed before being brought into engagement with said fillerwise yarns, said loops normally when in extended position enclosing and shielding said fillerwise yarns from view and forming substantially the entire exposed surface of said floor covering.

3. A loop pile floor covering as set forth in claim 2 in which said fillerwise yarns are composed of a material selected from the group consisting of natural or synthetic rubber, synthetic sponge and synthetic foam rubber.

4. A loop pile floor covering as set forth in claim 2 in which said fillerwise yarns are composed of a synthetic foam rubber and include a non-stretchable yarn to limit the stretch thereof.

5. A loop pile floor covering as set forth in claim 2 in which said fillerwise yarns are composed of a synthetic foam rubber and include -a wrapping of a non-stretchable yarn to limit the stretch thereof.

6. A loop pile floor covering as set forth in claim 2 in which said fillerwise yarns are composed of a synthetic foam rubber and include a core of a non-stretchable yarn to limit the siretch thereof.

7. A loop pile floor covering as set forth in claim 2 in which said fillerwise yarn comprises a soft spun yarn. 5
