Modified copolyester(MCPET)/ nanoparticle composites were prepared by in-situ polymerization, and the corresponding fibers were acquired by melt spinning. The structure and properties of fibers were characterized. It was found that nanoparticles are well dispersed in the MCPET matrix, and the size of the nanoparticles are about 100～500nm. Compared with the MCPET, the crystallization rate and crystallinity of the MCPET/nanocomposites increase due to the nucleating effect of nanoparticles. The introduction of the nanoparticles enhanced the orientation degree and the strength of the fibers. The specific resistance of the fibers prepared by the MCPET/ nanoparticles composites (with 1 wt% of nanoparticles) is about 2.1×108 ??g/cm2, which is much lower than that of the neat PET fibers (about 3.8×1013??g/cm2), and the hybrid fibers show a better anti-static property.

Polyester has outstanding wearability, while sericin protein has excellent biocompatibility. If they are combined together, a high functional polyester/sericin protein fabric can be produced with both remarkable wearability and biocompatibility. In this paper, polyester was first semi-encased with sucrose ester under high temperature to endue it with reactable groups, and then grafted with sericin protein by crosslinkage compound. SEM photograph showed that a layer of materials had been appendiculate on surface of polyester fibre. FTIR indicated that sericin protein had been grafted on polyester. DSC showed that thermal stability of polyester had been improved. XRD showed that the crystalinity degree of encased polyester decreased while that of grafted polyester treated by acetic acid increased slightly. The wearablity of sericin protein/polyester was also studied. The results shows that sericin protein was fastened on the surface of polyester fabric. With the increase of sericin protein content on polyester, the moisture region increased monotonously; antistatic property was improved; the cockle elasticity decreased a little and flexural stiffness increased dramatically. Soft treatment was applied to improve its pliancy.

Research on surfactant-dye interaction has important theoretical and practical values. The interaction between a quaternary ammonium Gemini-type surfactant (EB-CDAC) and C. I. Direct Blue 199 with copper phthalocyanine structure was investigated by conductivity testing, ultraviolet spectrophotometry and surface tension measurement. The results indicated that the combination of the dye and the surfactant induced dye λmax red-shifted. The absorbance of the mixed solution decreased when the concentration of EB-CDAC was lower than its CMC and increased when the concentration was higher than its CMC. The dye-surfactant complex formed by electrostatic forces occupied the air-water interface at first. With the increase of the concentration of EB-CDAC, the complexes on the air-water interface were replaced by EB-CDAC molecules gradually.

Through the solubility parameter calculation of disperse dyes, coating agents and organic solvents as well as the analysis of their behavior, the mechanism of color change of the coated polyester fabrics in manufacturing and storage was studied in terms of solubility parameter theory. The results show that the dye migration both in fabric coating manufacturing and storage was related to the solubility parameter of coating agents and organic solvents. In manufacture process, the coating agent with similar solubility parameter to disperse dyes’ would cause dye migration from inner fiber to fabric surface, but relieve the color change caused by uneven migration of disperse dyes during storage. The main reason for uneven dye migration during storage was the volatilization of entrapped solvent, and the uneven dye migration was more easily to occur when the solubility parameter of solvent and disperse dyes were close, or the boiling point of solvent was too high or too low. In order to reduce color change phenomenon of the coated polyester fabrics, close solubility parameter between coating agent and disperse dyes as well as far solubility parameter between organic solvent and disperse dyes were chosen.

Abstract ：Modification of linen fabric is performed via UV initiated photografting of acrylic acid in this design. BP neural network and least squares regression modeling methods are used to predict the relationship between grafting ratio and air permeability under different conditions of photografting time, photoinitiator amount and concentration of acrylic acid, respectively. A three-layer BP network model with architecture of 1-10-1 is established after extensive discussion, including one node in one input layer representing grafting ratio, one node in one output layer representing variation of air permeability and ten nodes in one hidden layer. The activation function of sigmoid is selected. The optimum parameters, training step of 100 and training goal of 0.001, are determined. The correlation coefficient of BP neural network model is higher than least squares regression model, while the percentage error is lower. Therefore, BP neural network has higher simulation precision, which provides an effective predictive model for the relationship between graft ratio and air permeability.
