Abstract: In a method for increasing the cover of textile fabrics yarns are used, at least part of which exhibit potential fiber-spreading properties, which can be activated by removing from said yarns, processed into a fabric, the adhesive used for the fiber bonding in the yarn by means of a suitable solvent. The selected number of warp and weft threads per unit area is so small that on the one hand an optimal fiber spreading is obtainable, but on the other hand, after activation of the potential fiber-spreading properties, sufficient cohesion of the fibers in the fabric is retained for further processing of the fabric. After obtaining the desired fiber spreading the fiber bonding, partially lost through the activation, is at least partially restored.
