TECHNICAL POLYAMIDE FABRIC FOR MANUFACTURING SOIL-FILLING CONSTRUCTIONS Russian patent published in 2012 - IPC D03D1/04 

FIELD: textiles, paper.

SUBSTANCE: construction is made as a calico weave with a fabric weight of 320-380 g/m² from multifilament yarns obtained from the melt on the basis of poly-ε-caproamide characterised by a linear density of 93-187 tex, while the in the warp and/or filling at a specified interval additionally twisted yarns are entered and the intermediate longitudinal extension of the tissue is no more than 10% under load of not more than 25% of the damage force rating.

EFFECT: reduced tissue tension under static loading, while maintaining a high level of mechanical properties, improving the structure of tissue with increased filtration parameters and provision of long-term durability of tissue under adverse climatic conditions.
