铕有机配合物与聚酰胺共混纺丝及其防紫外性能研究
|
摘要
将稀土金属铕与有机化合物经固相法合成铕有机配合物,再与聚酰胺共混纺丝制得具有防紫外性能长丝,然后将其织成织物,并分析测试织物的孔隙率和防紫外性能,探究铕有机配合物质量分数对共混聚酰胺长丝性能及其织物抗紫外性能的影响。结果表明:随着铕有机配合物质量分数的增加,共混聚酰胺长丝的拉伸断裂强度、伸长率降低,强度变异系数增加,物理力学性能的稳定性下降。对比铕有机配合物共混聚酰胺长丝织物与普通聚酰胺织物,发现质量分数为0.5%的铕有机配合物的共混聚酰胺长丝织物具有较好的防紫外性能,而当铕有机配合物质量分数大于1.0%后,长丝织物防紫外防护等级达到50+的水平。此外也发现,孔隙率小、结构密实的织物具有更好的防紫外性能。
The rare metal europium and organic compounds were synthesized to produce organic complexes by solid phase synthesis. And then the complexes were blended with polyamide to weave the filament which had the anti-UV property. The filament was woven into fabrics. The porosityand anti-UV performance of fabrics were tested. The property of blend spinning filament and anti-UV performance of fabric along with the change of mass fraction of europium organic ligand were investigated. The results show that with the increase of mass fraction of europium organic ligand, the filament tenacity and elongation decreased, and the tensile variation coefficient increased. The polyamide filament fabrics blended with europium organic ligand and pure polyamide fabric were compared. The results show that the anti-ultraviolet property fabric woven by polyamide filament blended with 0. 5% europium organic ligand is better. When the mass fraction of europium organic ligand increase to 1. 0%,the level of anti-ultraviolet is 50 +. It's also find that the fabric with small porosity and compact structure has better anti-ultraviolet properties.
