7, 1956 D. P. MOORE DOUBLE FACED FILE FABRIC Filed June '7, 1955 INVENTOR United States Patent DOUBLE FACED PILE FABRIC David Pelton Moore, Glen Oaks, N. Y.

Application June 7, 1955, Serial No. 513,875

2 Claims. (Cl. 66-194) The invention relates to improvments in knitted pile fabrics, one object of the invention being a knitted pile fabric in which the fiber staple has its free ends disposed approximately equal upon each face of the fabric to produce a double-faced fleece or pile knitted fabric, this particular fabric being made on the apparatus and by the methods set forth in my two Patents Nos. 2,712,225 and 2,725,735.

By these means, the fiber staples are so combined with the basic yarn, that their approximate centers are locked in by each individual stitch, while the free ends during the knitting operation are suction parted to dispose approximately equal amounts of such free ends, so that the fabric in the knitting machine has these free ends projecting from each face of the fabric, and both sides can then be brushed and sheared when wool and when acrylates, nylon, Dacron, corn sugar fibers as Vicara, or combinations thereof are used, they are treated to remove the static, and can be made to stand erect, or by decating made to lie inclined or flat in one direction; or embossed, by heat and pressure to have designs that will not wash out with detergents and water.

In order to illustrate the present fabric, attention is invited to the accompanying figure of the drawing, in which a fragmentary section of a piece of this fabric is shown.

In making this fabric, the machines as shown and described in the above two noted patents can be used, either using latch or spring needles, the latter preferred, as the pile faces 11, are then above the needle hooks, and do not have to be pressed against the inner face of the cylinder as in latch needle machines, and the uptake is the only place where the free pile surfaces are in any manner crushed.

This fabric therefor consists of a basic yarn 2, which as in the above noted patents forms the basic web of the fabric, the fiber staple 3 composed of short lengths, and of the selected and desired length needed to produce a fabric to have the proper final pile length, is dotted into the hooks of the needles just prior to the reception of the basic yarn therein so that the yarn to a great extent is buried in the staple held in each hook, so that when the stitch is formed, the approximate centers of the fiber staple are locked in the curved portion of the stitch, and the fiber staple while thus held, and the points indicated in the above noted two patents, are acted upon by opposed suction nozzles to part the fiber staple, so that the free ends 4 and 5 are disposed as shown to provide a double-faced pile fabric.

When this fabric is removed from the machine, a single needle having been dropped to provide a plain yarn stripe the full length of the tubular fabric, the yarn at this point is cut to permit the fabric to be laid flat, and when the fabric is of wool, the fabric is washed, rinsed and dried, and then brushed and sheared on one side to secure the desired height of pile, and then similarly treated upon the opposite side. In this manner a doublefaced knitted pile or fleece fabric results, that is suitable for blankets, insulated garments, sleeping bags and other uses.

Where synthetic fiber staples are employed, the knitting operations are the same as described, but when the fabric is cut to form a flat fabric, the faces are slightly wetted, and then run through a static removing machine having double active faces, so that the fibers stand straight and erect upon both faces. After this treatment, where necessary, the fabric is passed through a shearing ma chine, same as in wool treament, until the desired length of pile is bad.

In any case, where it is desired to have the pile faces incline in one direction, the fabric is run through a decating machine, with heat and pressure to set the fibers simultaneously on both faces and in the same direction.

What is claimed, is:

1. A knitted fabric composed of yarn and short fiber staple and in which the yarn forms the basic web while the short fiber staple commingles with the yarn so that the approximate centers of the fibers are locked in the stitches with the free ends thereof so disposed as to provide a pile surface on both faces of the fabric.

2. A knitted fabric composed of yarn and short loose fibers so knitted that the short loose fibers cover the yarn, while the free ends of the fibers are so positioned as to have approximately equal amounts upon each face of the fabric to provide a double-faced knitted pile fabric.
