Aromatic polyamide filament having an enhanced weathering resistance |
摘要 |
<p>An aromatic polyamide filament comprises extremely fine inorganic material having a high refractive index of 2.0 or more and an extremely fine average particle size of 0.3 mu m or less and dispersed, in an amount of 0.1 to 5% based on the total weight of the filament, in at least a surface portion of an aromatic polyamide filament matrix; has an individual filament thickness of 0.5 to 50 deniers, a tensile strength of 18 g/d or more, an ultimate elongation of 3.5% or more and an initial modulus of 450 g/d; and exhibits an enhanced weathering resistance derived from the high ultraviolet ray-reflecting, shielding and absorbing properties of the extremely fine inorganic particles dispersed in the filament matrix.</p> |
