Medicated ultrafine fiber mats were prepared using electrospinning with polyacrylonitrile (PAN) as matrix and acyclovir as model drug. The mats were characterized by scanning electron microscope (SEM), infrared spectroscopy (IR) and in vitro dissolution tests. SEM images envisaged that the diameters of fibers increased slightly with the increase of acyclovir contents in the fibers, and that fine drug particles were observed clearly on the fiber surface when the ratio in weight of acyclovir to PAN was 20 to 100. IR spectra results showed that that acyclovir had fine compatibility with PAN. In vitro dissolution tests indicated that the initial burst effects were obvious, and even more manifest when the content of acyclovir in the fibers increased, and meanwhile the total drug release percentage increased. All the ultrafine fiber mats were able to control the release of over 60% of acyclovir sustainedly via diffusion mechanism. Electrospun medicated fiber mats may offer novel strategies for the research and development of transdermal drug delivery systems or topical drug delivery systems.

In vitro degradation of Polyglycolic acid（PGA）fiber by melting-spinning was investigated for a period of 9 weeks in phosphate buffered solution（pH=7.4）at 37 ℃.The degradation was studied with regard to the mass loss, tensile properties of the fiber, melting point, the degree of crystallinity and morphology of PGA fiber. The research showed that weight loss of PGA fiber during degradation was significant. After 2-week degradation, the weight loss speeded up obviously, and the weight loss reached about 80% at 6th week. But after 6-week degradation, the speed tended to be slow gradually. During the process of degradation, considerable changes in the mechanics and thermodynamics performance of PGA fiber had taken place. With duration of degradation, the melting peak moved to the low temperature and the melting point gradually reduced. The breaking force reduced gradually, and it basically had lost all of its strength after 4-week degradation. With duration of degradation, the diameters of PGA fibers became thinner; and crystallinity of PGA fiber in the degradation of 3 weeks gradually increased but gradually reduced afterwards.

The static absorption capacities of the sheath-core bicomponent composite cation exchange fiber for Zn2+、Cu2+ are determined. The absorption kinetics and the main factors affecting absorption capacities of Zn2+、Cu2+ are studied, and its chemical stability and regenerating property are probed. The results indicate that liquid film diffusion is its main controlling step. When the concentration is in the range of 0.005～0.2 mol/L, the adsorption for metal ions belongs to monolayer adsorption. The process of isothermal absorption can be described by Langmuir and Freundlich adsorption isothermal equation. The sheath-core bicomponent composite ion exchange fibers obtained have faster absorption rate for Zn2+、Cu2+. The maximal adsorption capacities for metal ions exceed 2 mmol/g. The best adsorption pH value for Zn2+、Cu2+ is at nearly pH value of 8.0～9.0. This type of ion exchange fiber has good absorption property and working stability to various of metal ions.

From the viewpoints of fiber morphological structure and surface friction, the compressional behavior of five fiber assemblies has been investigated sequentially by one-way compression, i.e. wool, cashmere, acrylic, goose down and kapok. Fiber morphological structure was one of the main influence factors for the compressional behavior of fiber assemblies. The conclusion that the contact numbers between fibers had nothing to do with the fiber crimp and cross section was verified. Simultaneouly, the compressibility of fiber assemblies depended on fiber arrangement intensively. Different arrangements led to different assembly structures and different sources of compressing force. In addition, there were distinct discrepancy for the forces compressing on the fiber assemblies in cylinder and without cylinder. It depended on that whether the assemblies could swell and deform freely.

Alkaline hydrolysis properties of modified polyester fiber containing soldium-5-sulfo-iso-phthalate(SIP) is studied. Experiments indicate that weight loss of the fiber has good linear relationship with treatment time at constant temperature and lower NaOH concentration, and the degree of fiber weight loss increases with the increase of SIP in the HCDP fiber. Besides treatment temperature, alkaline concentration, and treatment time, weight loss of the fibers is affected by profiled cross-section of fibers considerably. Owing to the different hydrolytic degree between HCDP and PET, after treatment, more microcellular structures on the surface of HCDP, indicating that the fiber has better water transportation ability.

The twist of the split-spun yarn was studied by the principle of the solo-spinning and mechanical theories that have three sections (conjunction points, the fasciculus above this point, and the yarns below conjunction points). We analyzed the twist of the split-spun yarns, the twist producing and distribution along the split-spun yarns. Finally, we concluded that there are correlation between the twist of fasciculus, the twist of yarns, and the condition of the fasciculus. We also concluded that the twist of the fasciculus is not a fixed value and so on. And, from the analysis of the twist for the conjunction points in the split-spun yarn, we brought forward the rules concerning the ratio of fasciculus to yarn twist. And, The correlation between the twist of fasciculus and the fibers’capability was investigated, pointing out that only when the twist of split-spun yarn are in critical value, the index of yarn will be the best.

Different to that of short-fiber yarn, textured yarn’s mass evenness has nothing to do with its appearance evenness. According to the results of EIB test, there are not obvious difference between the air-jet textured yarn and the short-fiber yarn in the case of CV, while the differential shrinkage filaments air-jet textured yarn share the same CV with the short-fiber yarn; The air-jet textured yarn’s appearance diameter changes more than that of short-fiber yarn; For the air-textured yarn, the frequency of appearance diameter diversification mainly stay in -25%~25% short segment area. For the differential shrinkage filaments air-jet textured yarn, it’s in -25%~50% longer segment area, this is also the same as short-fiber yarn. According to Uster® test, both air-jet textured yarn and differential shrinkage filaments air-jet textured yarn have a lower CV than the short-fiber yarn, this is beneficial to maintaining their mechanical properties.

7 kinds of blended knitted fabrics with different blending ratioos of milk casein fiber, cotton and coolmax fibers were taken as research objectives with a view to investigating the wearability of milk casein fiber fabrics. The warm- retention property, water vapor permeability, air permeability, and hygroscopicity of the blended knitted fabrics were tested, and the thermal-moisture comfort of fabrics with different fiber contents was studied. By using the gray cluster analysis, the integrated evaluation of thermal-moisture comfort of the fabrics under different environmental conditions was conducted. The experimental results show that the fabrics containing milk casein fibers has better warm- retention and water vapor transmission properties. In summer, the thermal-moisture comfort of the blended fabric improves as the content of milk casein fibers increases. However, in winter, variation of the content of milk casein fibers has no significant effect on the fabric thermal-moisture comfort.

In allusion to the traditional contour tracing arithmetic which can only work on binary images and is not able to handle the interlinking phenomena among objects, this paper introduces facula diffusion model based on the principle of human vision, and illustrates its controlling parameters including approximation, closing, length-limiting and hit-rate. This model works directly on grayscaled images and can automatically separate the interlinked objects. Taking advantage of the facula diffusion model, three new feature indices including acreage, abnormity and fluctuation are composed to describe the object shape in its dimension, the departure from roundness and the roughness of its contour respectively. It turns out that the new model can extract the contour of fiber cross-section accurately and the feature indices built on this model can reflect the shape characters of the object in an effective way.

To study the primary components and the corresponding attributes of the tactile texture space of textile fabrics, this paper, based on the semantic experiments of implicit memory, obtained tactile texture descriptors and examined the relations between the frequency and average order of the descriptors. On this basis, the method of cluster and factor analysis in data mining is used to establish the perceptual dimensions of tactile textures from the perspective of cognitive science. The results from cluster analysis show that roughness-smoothness, hardness-softness and thinness-thickness are three dimensions of the tactile texture space. The fourth perceptual attribute would possibly be related to the viscidity. The results from factor analysis indicate that the cumulative contribution ratio of the five sets of factors reaches to about 67.69%, indicating that the results of the cluster analysis can explain the majority perceptual attributes of the tactile texture of fabrics.

In order to study the characteristics of heat transfer within the clothing exposed to fire, the paper develops a numerical model of heat transfer in emergency rescue protective fabrics sheathing a cylinder simulating a human limb. The column inside the cylinder system simulating the human body is assumed to keep at a constant temperature of 37℃. This model has taken into consideration the protective clothing absorbing the radiant heat and the change of its properties resulting from it. Temperature distribution along the radial between the clothing and skin was calculated with the help of a finite difference, complete implicit scheme. Henriques’ skin burn equation is quoted to predict the time needed leading to a second-degree thermal burn based on the calculated temperature value. The results coincide with experimental values. The numerical model shows that the cylindrical geometry has a significant effect on the thermal protective performance of the intrinsical heat-flame resistant fabric of polymer nature. At the same time, the method also helps to establish a systematic way for analyzing heat transfer in other cylindrical applications.

To meet the requirements of better performance and lower cost in designing the control system for industrial sewing machines, this paper presents a design of AC servo control system for permanent magnet synchronous motor, which uses linear hall effect sensors as the motor feedback devices. Because the linear hall effect sensors mounted on the stator produce an analog output signal which is proportional to the intensity of the induced field by the permanent magnet and is exactly in phase with back-EMF, the position and speed information of the rotor can be obtained from the measured linear hall effect sensor signals by using the linear hall effect sensors in place of optical encoders and latched hall effect sensors normally used. Furthermore, the novel field-orientated control algorithm is achieved by generating current references in the three phase stationary frame without the stationary-to-rotating reference frame transformation and its inverse. This AC servo control system is applied in industrial sewing machines, and the experimental results show that the proposed control system is feasible, reasonable and has better performance and lower cost.

The paper carries out further researches about the algorithm of reconstructing and simplifying the surface model of three-dimensional costume, and adopts the Discrete Marching Cubes （DiscMc）algorithm to apply the discrete idea to simplifying the triangle interface, thus the interpolating value which is time-consuming is reduced to the lowest so that the rebuilding efficiency and effect of the former system are greatly improved. The triangle interfaces in the same plane and in the neighbour are incorporated, It gets an excellent ratio of simplification, high efficiency of the algorithm, keeps a restricted loss of precision and the microstructure of surface model of costumes without being destroyed in the simplifying process of DiscMC. It is very obvious that the DiscMC is advantageous over other simplifying algorithms. In addition, it is seen from the descriptive experiment about the algorithm that the DiscMC is only confined to the point whose density of raw data is on the grid and simplifying is conducted only one time rather than repeatedly, therefore, it is very suitable for simplifying the 3-D surface model of costumes.
