Abstract: This paper mainly introduces the structures，properties and applications of axial warp-knitted fabrics, warp-knitted spacer fabrics and warp-knitted/nonwoven compound fabrics. The huge advantages of warp knitting technology in the production of high-strength and environment-resistant geotextiles are introduced in details. It can provide guidance for the application of warp knitting technology in the field of high-strength and environment-resistant geotextiles.

Key words: axial warp-knitted fabric; warp-knitted spacer fabric; warp-knitted/nonwoven compound fabric; high strength; environment resistance
