Functional composite textiles has been improve the grade of textile products andvalue-added, and expand the textile application areas of research hot spots. Polyester fiber hasmany excellent comprehensive performance, high breaking strength, good drape, high elasticmodulus, crisp, good wear resistance, dimensional stability, low price, so widely used in garmentfabric, decorative fabric and industrial fabric. However, due to the chemical structure, crystalstructure and surface properties of polyester and other factors, make its have poor hygroscopicity,easily electrostatic and other defects, giving textile processing and bring inconvenience, directlyaffect the scope of its application. In addition, the polyester fiber is the largest output in theworld, and is the most widely used synthetic fibers, its molecular structure have an aromatic base,so it has a certain absorb ultraviolet performance,and it is the best of the UV resistance inconventional chemical fiber. However, it can not be called ultraviolet prevention products.If given antistatic properties of polyester fabric, can bring new vitality of the polyesterindustry.In addition,there has been more and more patients with skin cancer in recent years, thisis due to prolonged UV direct skin related. Therefore UV protection textiles has been growingattention by people.And if the two function combined to give the fabric, that is the preparation ofantistatic and anti-ultraviolet textiles, not only has important applications in industrial, medical,military products, and has wide application in daily life.This research using TBOT and TEOS as precursor, HAc as a catalyst, water as a reactionsolvent, prepared by sol-gel method SiO2/TiO2composite sol, Ag+-SiO2/TiO2composite sol andFe3+-SiO2/TiO2composite sol. And they were applied to the as antistatic and anti-ultravioletagent on polyester fabrics by dip-padding technique. The optimum technologic parameters weredetermined. Successfully implemented in a building at the same time of antistatic polyester anduv protective properties of functional textiles, to prevent ultraviolet antistatic material researchdevelopment and practical application to lay the foundation. The experimental results showed that the antistatic and anti-ultraviolet property of thepolyester fabric treated by composite sol were improved.The optimal ratio of composite sols forantistatic treatment was just like that Ti%/(Ti%+Si%) was0.33, the optimum sol concentrationwas0.75%, Ag+-dopping4%, Fe3+-dopping0. At this point, the half-life of the fabric was0.01sand0.52s, respectively. And after30times of washing, the half-life of the fabric still has4.57sand9.72s, respectively. Thus it has a certain antistatic durability. The optimal ratio of compositesols for anti-ultraviolet treatment was just like that Ti%/(Ti%+Si%) was0.8, the optimum solconcentration was0.75%, Fe3+-dopping0.06%, Ag+-dopping1%. At this point, the UPF of thefabric was132.8and136.27, respectively, the TUVAof the fabric was3.73%and3.81%,respectively. And after30times of washing, the UPF of the fabric still has110.64and113.79,respectively. Thus it has a certain anti-ultraviolet durability.
