Silk fibroin(SF) and gelatin were dissolved in formic acid with different mass concentrations and the resulting spinning solution was electrospun into hybrid nanofibers whose morphology was observed by using SEM.The influence of technical parameters on the morphology and diameter of the hybrid nanofibers was investigated and a comparison was made between the hybrid nanofibers and pure SF nanofibers electrospun under the same process conditions.The results showed that hybrid nanofibers have an average diameter of(83.9 nm) and even distribution of fiber diameter when the proportion of SF to gelatin is(70∶30,) mass concentration of the spinning solution is 11%,polar distance is(13 cm,) and voltage is(22 kV.) The application of gelatin in the hybrid spinning solution is beneficial to solving such problems as breaking of fiber and beads appeared on fiber surface which are accompanied with electrospinning of SF spinning solution with low mass concentration.It will probably be applied in bioengineering.

This paper covers the test for the permeability,hygroscopicity,and shrinkage of untwisted knitted fabrics and makes a comparison with the relevant indexes of twisted knitted fabrics.The permeability of the untwisted knitted fabric is almost twice as much as that of the twisted fabric.The drying viscosity of the untwisted fabric is faster than that of the twisted fabric.This demonstrates that the untwisted knitted fabric has better air-permeable and moisture transmitting properties as compared with the twisted.In addition,the permeability,moisture transmittance,tensile strength,bursting strength,and draping of the untwisted woven fabric are also tested.The untwisted yarn fabrics have good serviceability and potential for development of new products.

According to differential capillary effect of fabrics, various knitted functional sportswear fabrics are made of the moisture-transfer and dry-fast properties of abnormal cross section polyester filaments with common weaves and structures.The test results and comparative studies reveal that the larger the difference of the linear density per filament between the inner layer and outer layer of the fabric,the more prominent differential capillary effect of fabric.The differential capillary effect differs in fabrics with same linear density of the inner and outer layers fiber but different weave structures.The fabric with three-layer weave structure has the best differential capillary effect.

Flax fiber was used as the reinforcing material to commingle with polypropylene (PP) filaments,producing a core-spun yarn with the flax as core and PP filament as outer sheath.The commingled yarns were woven into 2-D fabric which was used as the prefabricated material.By hot-pressing technology the prefabricated material was shaped into laminates.The fracture mechanisms and the factors affecting the impact resistance of the laminates were studied through analyzing the test results and fracture photographs.It showed that the impact resistance of the laminates with twill weave is prior to that with plain weave made by the same technological parameters.At the same time,the resin,reinforcing fiber,the number of layers and impact velocity all exert effects on the impact resistance.

In order to obtain NIR camouflage,the cotton and polyester/cotton fabrics were dyed by using vat dyes and disperse dyes respectively.The results indicate that the vat blue L-MG and 83962 are of the same class.The near-infrared reflective spectra of the dyed fabrics are shifted to the long wavelength as the concentration of vat blue L-MG increases,and the amount of red shift is correlated to the peak value of visible reflective spectra.When the concentration of the dye is 1%～2%(o.w.f),the reflective spectra of the dyed fabric are very close to that of the green leaves in the NIR region.Except fabrics with satin or honeycomb weaves,the reflective spectra of the fabrics dyed with different dye concentration show no difference in the visible light region and very slight difference in the NIR region.The near-infrared reflective spectra of the dyed fabric are closely related with the dye which has the largest red shift in the NIR region.

Neckline performance evaluation is an important part for knitted sweater.In order to implement classification automation of testing system,kernel Fisher discriminant analysis(KFDA) is proposed for identifying the grade of new testing samples.Classified samples are divided into two parts: training samples and testing samples.Input space is mapped into feature space by kernel function,projection vector is acquired and discriminant functions is constructed in feature space,subsequently,identification effect is verified by testing samples. Finally,identification effects of KFDA,back promulgation neural network(BPNN) and radial basis function neural network(RBFNN) are compared.Experiment results show that KFDA method is more effective for identification of new samples.

Most of the knitted wear manufacturers still use the traditional specification algorithms to make pattern.This method is short of adaptability and lack of theoretical basis,and the resulting apparel has some drawbacks in body fitness.The pattern of the knitted apparel is required not only to meet the functional needs,but also to guarantee the rationality and aesthetics of the style. Thus,the prototype design of weft knit(women′s) wear is created by a method combining the 2-D and 3-D design technologies and applied to the manufacture.This is meaningful for developing the pattern design theoretical system which is accommodated to the development of knitted apparel.

The pressure supply system of the atomizing nozzle,being characterized by nonlinear and time-varying,is rather difficult to be described by the accurate mathematical model.Effective control of the system is hard to realize by using normal PID or fuzzy control alone.In this paper,an approach of fuzzy-PID hybrid control is presented by utilizing the advantages of both normal fuzzy and PID controller for the purpose of improving the dynamic and steady state performance of the control system.Thus,the control of the pressure supply system of the atomizing nozzle is executed in such a way that in the region further away form the working point,it mainly depends on fuzzy control,and near the working point,it mainly depends on PID control.The simulation and experiment show that the hybrid controller is able to control the supplying pressure at the preset value efficiently.It features quick response,high steady state accuracy and perfect steady robust performance.
