| The subject systemized the two effect which including anti-ultraviolet and anti-pilling, to research the double effect of the polyester-cotton fabric in this paper. TiO2 hydrosol was prepared, the effect of preparaed process was studied and its preparation conditions were improved. Then the anti-ultraviolet or anti-pilling finishing effect was compared among TiO2 hydrosol, conventional anti-ultraviolet finishing agent and anti-pilling finishing agent. Optimum agent and its optimal technology conditions were selected. The technology and conditions of the double function finishing—anti-ultraviolet and anti-pilling were researched. The study used Martindale pilling test method to measure the pilling grade and evaluated the performance of anti-ultraviolet by measuring the ultraviolet transmittance and calculating the UPF values.The results of the study show that:In the sol-gel methods applied to prepare TiO2 hydrosol, the effect of Ti(OBu)4 with the amount of water,the chelating agent, the catalyst and reaction time.on prepared process was studied The particle size of TiO2 hydrosol was tested by laser particle sizw analyzer,steady time was used to verify the stability of TiO2 hydrosol, and its preparation conditions were optimized to obtain the best preparation conditions.Among the conventional finishing agent, CTA-765 has a better anti-ultraviolet performance and FK-833 has a better anti-pilling performance, but each function of TiO2 hydrosol is superior to the two agents above.Based on its double function, the best finishing conditions of TiO2 hydrosol are as follows:the amount of TiO2 hydrosol is 50%, baking temperature is 130℃, baking time is 3min. After the finishing, the UPF value of the fabric can reach 61, the pilling grade of the fabric can reach 4 to 5 level, and good durability and the ideal effect are achieved. |
