Method for improving light-resistance of aromatic polyamide fibers |
| 摘要 |
The light-resistance of aromatic polyamide fibers can be improved by heat-treating the aromatic polyamide fibers in the presence of urea and thiourea. The improvement in the light-resistance is enhanced by using aromatic polyamide fibers having an ultraviolet absorber incorporated therein.
