<p>PURPOSE:To provide the subject flat yarn having a specific flatness, a specific single filament strength, a specific elongation and a specific initial modulus, a low frictional coefficient between the filaments and a low stress strain on the twisting of the yarn, excellent in the strength utilization rate of the cord and useful for ropes, hoses, etc. CONSTITUTION:The objective flat yarn has a fiber flatness of 1.5-5 and a single filament fineness of 1-50 denier, and further has a strength of >=18g/de, an elongation of >=3.5%, and an initial modulus of >=450g/de as dynamic characteristics.</p> |
