Spacer fabric and use

A spacer fabric having a first planar warp-knitted fabric layer (1), a second planar warp-knitted fabric layer (2), and spacer threads (3) connecting the first and second planar warp-knitted fabric layers (1, 2), wherein the first planar warp-knitted fabric layer (1) is formed from at least a first thread system and a second thread system (5, 6) and has stitch wales (M) that run in a production direction (P), as well as stitch courses (R) that run in a crosswise direction, wherein the first thread system (5) is formed as a pillar stitch construction, and the threads of the second thread system (6) are guided, without forming loops, along the production direction (P), in an alternating sequence, so that proceeding sequentially from a center stitch wale that is disposed between a left stitch wale and a right stitch wale, the threads of the second thread system (6) are alternately guided around the left stitch wale and around the right stitch wale and then around the center stitch wale and then around the right stitch wale,

• and wherein threads of the first thread system (5) have a greater fineness than the spacer threads (3).
