Abstract (en)
Method for improving the crack resistance of a warp knitted product comprises providing the product with a number of stitch wales, a number of stitch rows and binding elements which extend over the rows. An independent claim is also included for an absorption filter material. Preferred Features: The binding elements are formed by smooth, textured and/or reinforced threads made from cotton, polyester and/or polyamide. The warp knitted product is additionally impinged with a spot-like applied adhesive for fixing an adsorbent for adsorbing chemical poison and chemical warfare agents. The adhesive is applied in an amount of less than 100 g/m 2>, especially less than 60 g/m 2>.
