Abstract
Abstract The present invention relates to a textile material for composite constructions, comprising a textile fabric having tied-in naps. To form a textile material which confers good mechanical properties on the composite and at the same time makes possible a durable attachment it is provided, that the tied-in naps being secured to the textile fabric incline from the textile fabric with at least two different lengths and pile directions, and being singly and alternately distributed on a front surface of the textile fabric in a substantially uniform manner.
