FIELD: manufacturing of nonwoven fabrics.
SUBSTANCE: reinforcing nonwoven fabric comprises two groups of fibers arranged at a right angle one to the other in the longitudinal and transverse direction of fibers. The fivers are locked by means of a binder. The both of the groups of fibers define a three-layered structure so that the group of transverse fibers is interposed between the top and bottom groups of the longitudinal fibers. The fibers of each group are made of glass roving with the linear density no less than 400 text. The method of making reinforcing nonwoven grid is proposed.
EFFECT: enhanced strength.
