Abstract (en)
[origin: EP0737763A2] Hybrid yarn comprises: (A) reinforcing filaments with: (i) an initial modulus of more than 600 (800-25,000, pref. 2000-20,000) cN/tex; (ii) a max. tensile strength of more than 60 (80-220, pref. 100-200) cN/tex; (iii) a max. elongation of 0.01-20 (0.1-7.0 pref. 1-5) %; and (iv) a degree of crimping of 5-60 (12-50, pref. 18-36) %; and (B) thermoplastic matrix filaments with a m.pt. at least 10 (20-100, pref. 30-70) degrees C below the m.pt. of (A). Also claimed are: (i) permanently ductile textile sheet contg. an amt. of hybrid yarn sufficient to have a significant effect on the ductility of the sheet; (ii) fibre-reinforced mouldings; (iii) a process for the prodn. of hybrid yarn from components (A) and (B) in a swirling or blow-texturing system in which at least (A) is introduced with an overfeed of 5-60%; (iv) a process for the prodn. of textile sheet as above (i) by weaving, knitting, laying or matting; and (v) a process for the prodn. of mouldings as above (ii) by forming textile sheet (i) at a temp. above the m.pt. of (B) and below the m.pt. of (A).
