FIELD: physics.
SUBSTANCE: invention suggests single fibre with longitudinal orientation of grooves and fabric made of it. Two-component fabrics made of these single fibres with grooves with use of blanket grout or cable coating have improved adhesion of coating; they also can include conductive coating. Besides, two-component single fibres can include mechanism indicating wear and tear. Invention also describes grooves made in surface of single fibres. In comparison with round single fibres improved adhesion with coatings is advantage of single fibres with grooves. Besides, fabrics containing these single fibres with grooves have better air management properties. Single fibres with grooves can be contained in fabric as threads laid in machine direction, in cross direction and both in machine and cross directions.
EFFECT: less air penetration, this is attained without additional coating or filling by thread.
