CORD FABRIC Russian patent published in 2005 - IPC

FIELD: textile industry, in particular, manufacture of knitted fabric for reinforcement of hydraulically isolating ruberoid-type roofing materials.

SUBSTANCE: cord fabric has through cells defined by transverse and longitudinal thread systems connected with one another: transverse weft and chain courses into which transverse weft is knitted. Transverse weft is defined by means of chemical single filaments. Chain courses are made from chemical complex thread. Diameter and density of arrangement of weft are selected depending upon transverse flexural rigidity of fabric. Width of through cells is determined on the basis of density of arrangement of chain courses and height is determined on the basis of density of weft single threads knitted into chain courses.

EFFECT: increased transverse flexural rigidity and provision for predetermined porosity of structure of cord fabric.
