FIELD: production of high-strength geotextile material.
SUBSTANCE: method for production of a high-strength geotextile material is claimed, comprising the steps of loosening and mixing at least two types of polymer fibres; fibrous canvas is laminated; connecting the fibrous web or converting the fibrous web into a sheet by needling on at least one needle punching machine; then thermal bonding of the needle-punched fabric and longitudinal and transverse cutting of the sheet is carried out; moreover, the first needle-punching machine contains needles of various calibres with notches.
EFFECT: fibres used consist of polyester and polypropylene fibres, which increases the strength of the non-woven material.
