Abstract: The invention concerns a polyamide-66-monofilament with improved initial modulus and with a titre of dtex 4 fl-150 fl. The strength of the monofilaments is at least 60 cN/tex for an extension of less than 25% and the specific LASE, in relation to the initial titre at 2% is at least 7.5 cN/tex, at 5% at least 18 cN/tex and at 10% at least 40 cN/tex, and the dry relaxation is less than 25%. The result is an improvement of about 40% in the LASE at 2% and an improvement of about 35% in the wet relaxation compared to standard polyamide (PA 66) monofilament. The precision fabric manufactured from the monofilaments disclosed is particularly suitable for direct use in direct printing onto woven fabrics and hollow articles.
