Fi l e d O c t l 9 l 9 65 BY I M, s 6M ATTORNEYS United States Patent M 3,479,244 LINKED FABRIC AND METHOD FOR MAKING SAME Peter P. A. Burnett, Mount Clemens, Mich. (5645 Forman Drive, Birmingham, Mich. 48010) Filed Oct. 19, 1965, Ser. No. 497,797 Int. Cl. D04h 3/05, 3/12 US. Cl. 16158 5 Claims ABSTRACT OF THE DISCLOSURE A linked unwoven fabric and process for making the same which comprises a plurality of parallel strands crossed by a second set of strands and overlaid by a third set of strands parallel to the first strands wherein the first and third set of strands are arranged in pairs and joined at junction points between the second set of strands to form a plurality of relatively large loops which entrap the cross strands, thus forming a fabric material without weaving.

This invention relates to a linked fabric and more particularly to that type of fabric which is not woven but which is created by adhering certain strands together. With the advent of synthetic fibers which are of the extruded type made from numerous synthetic materials and plastics, it is known to create a fabric material Without Weaving by adhering crossing strands of Warp and woof filaments either by adhesive or by other means of creating adhesion.

It is an.object of the present invention to provide an improvement in fabrics of this nature to create a more comfortable feel and a looser construction than can be accomplished in previous fabrics.

It is a further object of the invention to provide a fabric of this improved type without increasing the cost of the fabric and to create a fabric which permits considerable flexibility in design due to the inherent nature of the construction.

It is a further object to provide a fabric which has a better stretch characteristic particularly when there is a bias force.

Briefly, the invention consists of a fabric which has pairs of strands running in parallel direction in general overlying each other with cross strands positioned between the double strands of each pair. The double strands are then adhered to each other between the cross strands so that the cross strands are trapped in spaced loops along the fabric in a direction transverse to the double strands.

Other objects and features of the invention relating to details of construction and operation will be apparent in the following description and claims.

Drawings accompany the disclosure and the various views thereof may be briefly described as:

FIGURE 1, a perspective view of a segment of a fabric showing the general construction.

FIGURE 2, a modification showing the manner in which the cross strands may be anchored to create a different design and effect.

Referring to the drawings, the fabric shown in FIGURE 1 may be formed of a number of different types of yarns or filaments either of the monofilament or multifilament or staple fiber type in the form of extruded filaments or spun yarn. The invention is particularly adapted to that type of filament which is responsive to heat sealing or sealing by adhesive but most any type of filament or yarn which can be adhered to itself can be utilized.

In general, the fabric consists of a plurality of pairs of strands 20 and 22 which are arranged in parallel relation spaced from each other in any desired spacing. The

3,479,244 Patented Nov. 18, 1969 bottom strands 20 can be disposed in parallel spaced relation and then overlayed by transverse strands 30 also spaced from each other at any desired distance. Then the top strands 22 can be disposed to overlie the bottom strands 20 in parallel relationship and in generally the same plane. The double strands are then adhered at the points A, B, C and D and so forth to form junctions at those points and to leave relatively large loops 32 in which the cross strands 30 are locked. Thus, without the necessity for the usual weaving shuttle arrangement, the fabric is created.

It is possible that in utilizing filament strands which are flexibly extruded that they may be adhered together prior to complete setting without the use of any additional heat or adhesive material. It is also possible to use heat sealing, dielectric sealing, ultrasonic means for adhesion which is known today in connection with plastic materials.

Adhesives of various kinds could also be used at the juncture points including elastomeric or foamed adhesives. It is, of course, possible to vary the feel and characteristics of the yarn by altering the diameters of the double strands and the cross strands to create any number of different combinations as is characteristic in the manufacture of fabric generally. The loose relationship between the cross strands 30 lying in the loops of the double strands gives the fabric a generally flexible and loose feel which is possible in connection with fabrics which are created by positive bending of the strands as they cross each other.

In FIGURE 2, a modified structure is shown to illustrate the versatility of the construction. In this case, the double strands 40, 42 are joined as previously indicated at points A, B, C, D and so forth to create loops 50, 52 and 54. The cross strands 60, 62, 64, however, are angled relative to the double strands so that strand 60, for example, passes through loop 52 of the first double strand and loop 50 of the second one. Similarly, strand 62 passes through loop 54 of the first double strand and loop 52 of the second and loop 50 of the third and so on. This creates a different appearing fabric and can be utilized to create fabric designs in connection with a herring bone design and the like. Otherwise, the construction of the fabric shown in FIGURE 2 is the same as in connection with FIGURE 1.

I claim:

1. A linked fabric for use as clothing or the like comprising one set of a plurality of pairs of first and second filamentary strands generally parallel with each other and separated from each other by predetermined spacing in a. direction transverse to said pairs, the first and second strands of each said pair adhering to each other only at points spaced lengthwise thereof and forming a loop between each adjacent pair of adherence points, and a plurality of filamentary cross strands generally parallel with each other and separated from each other in the lengthwise direction of said pairs, said cross strands running transversely of said pairs and through said loop thereof with each said cross strand being loosely trapped by a series of said loops spaced from each other lengthwise of that cross strand, all of said first strands lying on one side of said cross strands, and all of said second strands lying on the other side of said cross strands.
