Abstract: Based on discussing the structures of the ultra-high-gauge spacer fabrics, this paper analyses the difference in structures and properties between ultra-high-gauge warp-knitted spacer fabrics and conventional ones and explains related knitting machinery and knitting principles. And then, the paper proposes a complete knitting process and introduces the fabric coating and finishing method, and finally sums up the applications of ultra-high-gauge spacer fabrics.

Key words: warp knitting; two-needle bar spacer fabrics; ultra-high-gauge; knitting principle; knitting process
