Abstract (en)

[origin: WO9850612A1] The invention relates to a filling yarn made of a thermally protected polyamide 6.6 multifilament for tyre cord fabric with a total titer of 100-400 dtex. This filling yarn is also raw yarn, and is characterized by: a SLASE of 6 cN/tex to 12 cN/tex at 80 % elongation; a maximum tensile stress strain of 150 % to 300 %; a strength of > 14 cN/tex; a reversibility limit of 5 cN/tex to 10 cN/tex; a thermal shrinkage force of 0.15 cN/tex to 0.8 cN/tex at 160 DEG C; free shrinkage > 1 % at 160 DEG C. The invention also relates to a method for producing a filling yarn from thermally protected polyamide 6.6 multifilament for tyre cord fabric. In this method, polyamide LOY filaments are stretched between 10 and 200 % before being swirled at least 10 knots/m by a compressed gas.
