Abstract

A fabric tape having loops for complementary attachment to a hook-carrying member of a hook-and-loop fastener assembly. The fabric tape includes a fabric backing having a front face and a rear face; and a multitude of elongated yarn loops formed on the front face of the backing, at least some of the loops defining a clockwise-extending axis with reference to the front face of the backing and at least some of the loops defining a counter-clockwise-extending axis with reference to the front face of the backing. The loops are positioned in uniform ranks and files on the front face of the backing.

Claims

1. A nonelastic fabric tape having loops for complementary attachment to hooks carried on a member of a hook-and-loop fastener assembly, said fabric tape comprising:

(a) a narrow flat knitted backing having a front face and a rear face and formed of knitted warp and weft yarns forming a nonelastic backing; and

(b) a plurality of loop yarns attached by knitting stitches to said warp yarns at spaced-apart points to form upstanding loops on the front face of said backing, at least some of said loop yarns being canted in a first direction with reference to the front face of the backing and others of said loop yarns being canted in a second direction with reference to the front face of the backing opposite said first direction, said loop yarns being attached to said warp yarns according to the pattern wherein;

(1) each of said loop yarns being attached to a first warp yarn at an intersection of said first warp yarn with a first weft yarn;

(2) said each of said loop yarns being attached to said first warp yarn at an intersection between said first warp yarn and a second weft yarn adjacent said first weft yarn without forming an upstanding loop between said intersections;

(3) said each of said loop yarns being attached to a second warp yarn adjacent said first warp yarn at an intersection between said second warp yarn and a third weft yarn adjacent said second weft yarn, said loop yarn forming the upstanding loop between said second warp yarn and a third weft yarn adjacent said second weft yarn; and

(4) said first and second warp yarns are adjacent to each other.

2. A fabric tape according to claim 1, wherein said first and second warp yarns are separated by at least one other warp yarn.

3. A fabric tape according to claim 1, wherein said first and second weft yarns are adjacent to each other.

4. A fabric tape according to claim 1, wherein said first and second weft yarns are separated by at least one other weft yarn.

5. A fabric tape according to claim 2, wherein said loops extend along the length of the tape in an alternating canted orientation.

6. A fabric tape according to claim 1, wherein approximately one-half of the loops in a group of adjacent courses are alternately canted in one direction and in another direction.
