Electrospinning method was used to fabricate PVA and PAN nanofibers.The effect of solution mass concentration and conductivity on electrospun fiber morphology was investigated by scanning electron microscopy(SEM).The result showed that the beads decreased and fiber diameter increased with increasing solution mass concentration which was found to have considerable effect on bead-free nanofibers and fiber diameter.Solution conductivity was improved by adding different LiCl mass concentrations into electrospinning solution.With increasing solution conductivity,fiber′s discrete coefficient decreased remarkably.Thus it is concluded that solution conductivity is the primary factor influencing the discrete coefficient of the fiber.

To evaluate the practicability of hollow fiber polypropylene membrane modified by cysteine(PP-g-Cys),its thermal stability and mechanical properties were analyzed by dynamic mechanical thermal analysis,thermogravimetry and tensile test.The results show ultraviolet irradiation has little effect on the mechanical property of polypropylene hollow fiber membrane in N2,whereas it decreases the break strength of the membrane in atmosphere.The elongation at break of PP-g-Cys descends with the increase of grafting degree.And the glass transition temperature(Tg) of PP-g-Cys drops,that is,the macromolecule becomes softer.The cysteine grafted side chain on PP-g-Cys membrane is thermally unstable,the its highest application temperature of the modified membrane is 212.4℃and 191.5℃in N2and O2respectively.

To investigate the influence of dry-heat treatment on the structure and properties of AN(acrylonitrile)-g-Casein fibers,the scanning electron microscope,fourier transform infrared spectroscopy,and X-ray diffraction were used.The results indicated that the dry-heat treatment below 140℃had slight influence on the yarn shrinkage and whiteness and improved its strength.When temperature of the dry-heat treatment exceeded 140℃,the fibers exhibited distortion of the fiber,increase in yellowing and decrease in crystallinity.140℃was found to be the critical temperature of AN--gCasein fibers for dry-heat treatment.

Chitosan fibers with different degrees of acetylation can be prepared by controlling the ratio between acetic anhydride and the fiber.This paper studied the absorption and antimicrobial properties as well as the tensile strength of the acetylated chitosan fibers and wound dressings thereof.The results showed that the properties of chitosan wound dressings were affected by the degree of acetylation.The partially acetylated chitosan fibers can absorb a large quantity of water into the fiber structure when in contact with water,making the partially acetylated chitosan dressing more absorbent than the original dressing.The wet strength and the antimicrobial properties of the partially acetylated samples were poorer than the original untreated samples.

The flow patterns affected by the nozzle structure parameters and the velocity at jet orifice exit inside the nozzle of air jetvortex spinning were investigated by the method of numerical computation.The results show that the negative pressure along the nozzle axis enhances first,and then diminishes along with increasing the jet orifice angle,and the negative pressure is maximal when jet orifice angle is 30 degree.The tangential velocity decreases along with increasing the jet orifice angle,however,the axial velocity increases along with increasing the jet orifice angle.When the velocity at the exit of jet orifice enhances,the greater the tangential and axial and radial velocity,the bigger the negative pressure along the nozzle axis.The outer diameter of the hollow spindle has comparatively small effect on the velocity of airflow inside the nozzle,however,when the outer diameter of the hollow spindle is smaller,the negative pressure along the nozzle axis will become higher.Increasing the distance between the hollow spindle and the entrance of the nozzle,the velocity and the static pressure inside the nozzle diminish and the negative pressure at the entrance of the nozzle increase.

For solving the problems of conventional low twist yarns due to their low tenacity,a specially designed false twister was installed between the front rollers and yarn guide on a conventional ring spinning frame for increasing fiber migration and entanglement in the spinning triangle,leading to a reinforcement of yarn strength.Thus the produced yarn has a low twist and a relatively high strength simultaneously.In addition,the yarn internal and external structures were examined and the radial fiber distribution,fiber path and yarn surface structure between the modified,normal and low twist conventional ring yarns were compared.The results reveal that the modified low twist yarn has a structure different from the conventional ring spun yarns.

In order to meet the demands of high speed weaving and diversified varieties of fabric,the let-off motion must be controlled accurately since electronic let-off system of loom has faced some new requirements.The traditional PID controller can not meet the requirements because of its typical complicated,tandem driving,time changing and non-liner winding system.Targeting the shortcomings of the traditional PID controller in loom electronic let-off and take-up motion control,a Fuzzy-PID tension controller is proposed for effective settlement of the problems of dynamic change of the non-liner system.Simulation by Simulink of MatLab is carried out on the basis of SAURER400 loom.The simulation experimental results indicate that the parameters of Fuzzy-PID are better than those of routine PID.This control method has good application potential for electronic let-off system.

The influences of different tempering temperatures and tempering time on the elasticity and hardness of knitting needles were studied.The results showed that tempering temperature has an obvious effect on surface hardness of knitting needles.The surface hardness lowers significantly along with tempering temperature rise.When the tempering time is over 60 minutes,surface hardness varies little at the same testing tempering temperature.And the elasticity of knitting needles is mainly influenced by tempering time.When tempering time is less than 60 minutes,the residual deformation value decreases greatly along with temperature rising.At the same time,the residual deformation value changes little and maintains a small value when tempering temperature is higher than 220℃and tempering time is over 60 minutes.The needles can be rendered not only good elasticity,but also high hardness(HV650 above) by an appropriate and plentiful low-temperature tempering process.
