<p>PROBLEM TO BE SOLVED: To provide a method for producing a webbing for a seat belt having excellent tenacity and energy absorption capacity, and to provide a seat belt webbing obtained by the method. SOLUTION: This method for producing a webbing for a seat belt is characterized as a polyester yarn which is substantially composed of a butylene terephthalate component and simultaneously satisfies >=0.8 intrinsic viscosity (IV), >=5.3 cN/dtex strength (T) at break, 10-25% elongation (E) at break and >=6% dry heat shrinkage percentage (ΔS) at 150 deg.C is used as warps, woven and then subjected to a limited heat shrinkage treatment. This webbing for a seat belt is characterized as the webbing is a webbing for a seat belt obtained by the method and has 20-50% elongation at 11.1 kN load.</p> |
