Abstract

Non-woven veil, constituted by continuous filaments, of the type formed by a plurality of adjacent longitudinal individual bands, characterized in that each individual band is constituted by, at least, fifteen continuous synthetic filaments, spun and stretched as a whole, which are distributed as width of the individual band in the form of loops formed by secondary beams constituted by filaments substantially parallel to each other, being densified in the form of secondary loops and smaller turns several times overlapped, a substantially greater spinning length of at least 500 100, within said provision in the form of primary ties; the individual laterally adjacent strips are overlapped without stratification at least 50% of their width; the loops and turns of an individual band are interspersed randomly with the overlapped part of the adjacent individual band; the weight of the veil on the overlapping parts; of the individual bands presents a variation no greater than 20% in relation to the total pitch of the veil; and the individual filaments forming the web have a titer of 1 to 20 denier and a tensile strength of 0.5 to 6 g/denier, the web having a weight of 10 to 1,500 g/m2.
