Abstract: A mattress closing tape formed of a crochet-type warp knitted construction comprises a set of parallel warp yams knitted in a series of lengthwise-extending chain stitches, first and second base filling yams of a first color (or other visual indicia) inlaid widthwise in opposing relation to each other through the chain stitches of the warp yarns to form a base fabric layer predominantly of such color at one fabric face, and third and fourth sets of multiple pattern filling yarns of a differing color (or visual indicia) inlaid diagonally in opposing relation to one another beneath the underlaps of the warp yarns to form a diamond pattern layer predominantly of such differing color at the opposite fabric face.
