Series after finishing this thesis, the disadvantage of poor cotton fabric wrinkle resistance, thereby improving the wrinkle resistance, and to give the fabric a new performance by finishing: anti-UV, anti-bacterial properties, in order to develop both the multiple functions of textile fabric new products, improve, and improve product quality, application grade, so the development of traditional textile fabrics toward multi-function, high-value-added textile direction. First, wrinkle resistant finishing of cotton fabric. In this paper, chitosan (CS) and citric acid (CA) complex technology for the preparation of anti-wrinkle finishing solution the chitosan amount of citric acid concentration, the amount of additives, curing temperature, curing time by changing the process parameters, two dip two rolling finishing of cotton fabrics; univariate analysis using anti-wrinkle finishing process of chitosan on cotton fabric, wrinkle resistant finishing by orthogonal test conditions:, the Chitosan 0.10% (owf) Citrate 9%, the DAP: CA = 1:1 (molar ratio), TEA 4%, the JFC 2ml / L, the baking temperature of 170 ° C, baking time 2.5min. S-4800 scanning electron microscopy to characterize the surface of the resulting fibers of the fabric after finishing, the results show that the small grooves in the surface of the cotton fibers by chitosan after finishing the chitosan to fill, the surface becomes relatively flat and smooth. uniform. Therefore, chitosan finish change the surface properties of the cotton fabric and the cotton fiber specific surface area decreases. The finished fabric physical performance test results show that: the finished fabric wrinkle recovery angle has been greatly improved, and has good whiteness, the radial fracture strength retention and good washing performance. At the same time, under the conditions of the finishing process, finishing solution for the complex of cotton fabric dyeing performance. Experimental results show that compared and not finishing the dyed cotton fabric, whether it is the first after dyeing finishing or after finishing the first staining activity and direct dye staining of cotton fabrics the K / S values ??were decreased, particularly cotton fabric dyed in the first after finishing decreased more is obvious. In addition, the complex finishing liquid silk performance. Experimental results show that the Silk CA and CS finishing, anti-wrinkle recovery angle significantly improved radial fracture decreased strength and whiteness. Instead of disodium hydrogen phosphate as a catalyst on the basis of the wrinkle resistant finishing formulation, the use of anatase type nano TiO2, and formulated into a new finishing liquid formulations, and using the optimum conditions of the above preferred fabric finishing, so that the fabric to obtain the composite effect of the anti-wrinkle, anti-ultraviolet and antibacterial. Obtained by experiment, nano-titanium dioxide concentration of 0.6% (owf), finished fabric has good antibacterial properties and washability performance, and the finished fabric UV transmittance significantly reduced. After this process is finished, the 280-320nm UV average transmittance reduced 84.6%, thus greatly improving the finished fabric UV resistance. Proved reasonable finishing process, chitosan and nano-TiO2 composite finishing not only get a good anti-wrinkle recovery angle of cotton fabric, breaking strength retention and better whiteness, and because of the nano-TiO2 and chitosan with the characteristics of the cotton fabric also has good UV protection, anti-bacterial properties and good fastness to washing, making the cotton fabric after finishing versatility, high value-added fabrics, and more to meet people for high-grade, The pursuit of the textile fabric with particularity.
