Abstract
Method for producing a textile unidirectional fabric, wherein at least one planar layer of multi-filament reinforcement threads arranged parallel to each other are woven with each other over transverse threads, wherein transverse threads having core-sheath structure and titer of 10 to 40 tex are used as transverse threads, wherein transverse threads have a first component, which structures sheath, and second component, which structures core, wherein first component has lower melting temperature than second component, first component is meltable thermoplastic polymer material and, via first component of transverse threads, adjacently arranged multi-filament reinforcement threads are connected to each other by hot melting, wherein alleys are formed in unidirectional fabric by interweaving multi-filament reinforcement threads together with transverse threads, by means of which a permeability of 10 to 600 l/dm2/min can be established. Preferred embodiment relates to method for producing unidirectional fabric having fleece. Further, a fiber preform, produced from unidirectional fabric.
