PET织物纳米TiO2抗紫外线整理及性能研究

通过对纯PET长丝织物浸轧焙烘纳米TiO2整理液,使织物表面附着纳米TiO2颗粒,并对织物表面形貌用SEM观察,发现纤维表面覆盖有一层纳米级颗粒,呈局部分散与团聚的不均匀状态.用紫外线防护系统测试织物,发现整理后织物具有较好的抗紫外线效果,且当纳米TiO2含量在1.5%时,抗紫外线效果最好.对织物皂洗20次后测试其抗紫外线效果,发现织物具有较好的耐洗性.对整理前后织物服用性能测试对比发现,纳米TiO2整理织物对织物服用性能几乎无影响.

Anti-ultraviolet ray reorganization and performance research on PET fabric with nanoscale titanium dioxide

The pure PET filament fabrics have been gained through padded and cured nanoscale TiO2 finish fluid,the surface of which is filmed nanometer TiO2 pellets.A coat of nanometer pellet on the fiber's surface has been seen by SEM,and the results presented non-uniformity station with some parts reunification and others separation.The treated fabrics have been tested by the ultraviolet ray protects system,and the results showed that better anti-ultraviolet ray effect is obtained after finished,when the content of nano-TiO2 is 1.5% the anti-ultraviolet ray effect is the best.The fabrics have nice washing fastness after soaped 20 times.By contrasted the properties of fabrics before and after finished,the nano-TiO2 finish has almost no influence to the wearability of fabrics.
