    摘要: 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.

    摘要: The method for continuous production of a multifilament stretchable weft yarn for tire cord fabric includes swirling polyester-POY-filaments with an initial titre of from 170 to 260 dtex by means of a gas having a pressure of from 0.5 to 3 bar in a swirling nozzle, and immediately thereafter, shrinking with an overfeed of from 40 to 80% at from 220.degree. to 240.degree. C. for at least 0.2 sec to form a stretchable multifilament weft yarn. This weft yarn has a rough surface with non-slip properties, a tenacity of greater than 7 cN/tex, an elongation at break of from 170 to 270% and a thermal shrinkage at 160.degree. C. of from +2% to -2%, measured at 160.degree. C. during 15 minutes at a pretension of 0.1 cN/tex.

    摘要: A process is disclosed for production of a heat-treated, coarse fiber of polyester-POY, whereby the fiber is first twisted and then continuously relaxed and tempered at a temperature from 130.degree. to 250.degree. C. to an extent from 20 to 55%. The slide-resistant fiber produced in this manner, displaying an elongation at break from 150 to 350%, a thermal shrink from +6 to -6% can be employed without further pre-treatment as weft yarn for tire cord webs.
