Polyester, because of its unique physical and mechanical properties, such as high strength, tensile, abrasion, corrosion and acid oxidizer excellent elastic recovery, becoming the world's most widely used synthetic varieties, but its poor moisture absorption, health function is poor, taking comfort performance is not satisfactory. The protein grafted onto polyester fabric polyester fabric surface can improve the performance and comfort of taking care functions. On the one hand grafted proteins, proteins with less, high utilization, and are in contact with the skin protein, good health care function; hand grafted proteins, the fabric wearability well maintained. However, due to the lack of polyester fiber surface reactive groups, to be given before the graft polyester fiber protein reactive groups can be, and is currently the main method of the alkali reduction processing based on sodium hydroxide, potassium permanganate oxidation treatment, plasma UV etc., etc. caused by irradiation, the above methods will make polyester fiber macromolecules strand breaks, leaving a loss of fabric mechanical properties and complex process, the equipment required is higher, is not conducive to mass production. In this paper, the high temperature and pressure, the polyester fiber polyester segment movement will occur, resulting in a large gap principle, the polyhydroxy compound containing sucrose fatty acid ester polyester fabric embedded in the surface, the surface can be given to polyester reactive group, while maintaining the polyester The mechanical properties of the fabric, and a crosslinking agent through the graft soy protein. The study includes a method of using mosaic large surface gives polyester reactive group may be, and the soy protein grafted to the mosaic surface of polyester, developed a high-soy protein / polyester new fabrics, studied the optimum grafting and the new fabric wearability and dyeing properties. Using infrared spectroscopy and scanning electron microscopy to determine the effect of mosaic and graft. Single factor experiments to determine the optimal grafting process; explores regain, water absorption, air permeability, moisture permeability, whiteness, flexible and rigid flexible and creasing grafting relationship; reactive dyes and disperse dyes were used carried out on the new fabric staining, reached the following conclusions: (1) a method using the mosaic inlaid into the sucrose fatty acid ester polyester fabric surface, so that the surface hydroxyl groups increased polyester, breathable fabric inlay after almost no change, Rigid increased, while the elastic crease recovery angle increased first and then decreased. The mosaic 1.45% of the cases, both the polyester surface can be sufficiently reactive group, and can ensure good wearability, the set rate of 1.45% soy protein graft fabric is used as raw material for the next step, the process of mosaic : 1% of sucrose fatty acid ester concentration, temperature 120 ℃, time 60min. (2) the use of a soft function crosslinking agent, the soy protein grafted to the mosaic of sucrose fatty acid ester polyester fabric, successfully developed a highly functional soy protein / polyester fabric. The single factor experiments, the optimum test graft: bath ratio 1:50, crosslinker concentration 4.1g / L, crosslinking time 30min, crosslinking temperature 100 ℃, while grafting with soy protein concentration The increase will gradually increase. (3) high-soy protein / polyester fabric hygroscopic than pure polyester fabric has been greatly improved, the grafting rate of 6.86%, the moisture regain a level of 1.05%, an increase of more than 2 times, whiteness, breathable almost no change in water vapor permeability, increased stiffness, elasticity crease recovery angle decreases, however modest, will not affect the performance of fabric. (4) grafted with reactive dyes on fabrics after soy protein stain, dye effect is obvious, but poor leveling. Use of disperse dyes in the Mosaic stage while dyeing, dyeing effect, grafted soy protein did not change after the dyeing depth.
