The paper discusses the properties and structure of the PET/PTT filaments under various tension conditions.As the tension increases,the sonic orientation factor of PET/PTT fiber increases and the Yang′s modulus also increases;the crimp shrinkage rate and the curve elongation rate of PET/PTT fiber decrease exponentially.Moisture thermal treatment of PET/PTT filament under fully relaxed state can impart it the most prominent crimp,but the Yang′s modulus of the fiber will decrease significantly;appropriate small tension is beneficial for both the crimp and the Yang′s modulus.

The attenuated law of flow field inside the nozzle block of the air jet vortex spinning is investigated by the method of numerical computation.Force analysis about a separated fiber in twisting chamber and the movement of a separated fiber affected by vortex in twisting chamber are discussed.The function relationship between the critical angular velocity of the fiber′s open-end twined over the hollow spindle and rotated around the air jet vortex spun yarn and the length of the leading fiber ends inside the yarn′s trail,fiber radius and so on is constructed.The critical angular velocity may judge whether the leading fiber ends pulled out the yarn′s trail or not,which can explain the generation of waste fibers and thin places.The critical angular velocity increases along with increasing the length of the leading fiber ends inside the yarn′s trail.On the condition of the same nozzle pressure,the fiber radius is bigger,waste fibers and thin places of the air jet vortex spun yarn are severer.Increasing nozzle pressure firstly can enhance the yarn strength,however,when the nozzle pressure exceeds the critical point,and waste fibers and thin places become more,which make the yarn properties deteriorate.Increasing negative pressure inside the nozzle and decreasing properly the distance from the front roller to the hollow spindle can decrease the generation of waste fibers and thin places.

The structures and performance of starch were modified by microwave radiation,which is a high efficient,energy saving and harmless technique.It was obviously observed that the microwave radiation changed the morphology and structure of starch particles.It was proved by the intrinsic viscosity test of starch that microwave radiation caused high frequency vibrations of the starch macromolecules,leading to fracture of glycoside bonds and degradation of macromolecules.The behaviors of sizing pastes and films of the starch,natural starch,oxidative starch and hydrolyzed starch radiated by microwave were also tested.The results indicated that the viscosity of sizing paste decreased after the starch was radiated by microwave and the decrease level was related to the duration of microwave radiation.And its adhesion to the fiber was also improved after microwave radiation.The breaking strength,elongation,abrasive resistance,flexibility and wettability were close to or higher than those of oxidative starch and hydrolyzed starch.

For accurate computation of the dye uptake rate of the fiber,this paper has developed a kinetics model for simulating the dye uptake rate by using multiple curve-fitting in combination with experimental data analysis on the basis of Hill equation.Knitted fabrics are dyed with Reactive Red RR,Weak Acid Green GS and Disperse Crimson S-2GFL respectively and the dye uptake rates at different times of these three groups of dyes are computed using this kinetics model and Hill equation and the results obtained are compared with the practical values measured.It showed that this new model is slightly advantageous over Hill equation,and in particular,the predicted dye uptake rate by the model is more agreeable with the actual value when up-taking of dye nearing the state of balance.

The main ways of textile industrial upgrading are discussed in the progress of new type industrialization.Applying the related theories on industrial upgrade and value chain,the five factors restricting the textile industrial upgrade are analyzed,including the remaining at the lower end in the value chain of textile industry,weakening in the traditional advantageous position,inadequate investment in R&D,the traditional production mode,and weak marketing force.Then,the paper suggests that in the new type industrialization,the textile industry should expand to the two ends of the value chain,i.e.,to the material development in the upstream and to the high profit zone of product design and market in the downstream.The textile industrial upgrading may be realized by exploiting the advantages of traditional competitive potential,promoting personnel quality,reforming manufacturing methods,motivating technical innovations and strengthening marketing force etc.Thus,the textile industry of China may embark on a path of new type industrialization and realize sustainable development.
