Blending the nano-tin (Sn) and polyacrylonitrile (PAN) to prepare Sn/PAN nanofibers by electrospinning. And using a scanning electron microscope and X-ray diffraction method, characterize the average diameter of fiber, distribution of diameter, distribution of Sn in the fiber and the degree of crystallinity after Sn electrospinning. The results showed that the degree of crystallinity increased after PAN electrospinning; the fiber diameter decreases with the spinning voltage increases or the distance increases; when the electrostatic spinning voltage is 14kV, solidification distance is 14cm, the average diameter of fiber is small and the distribution is uniform; Sn reunions when added to the PAN electrospinning, degree of crystallinity decreased; with the PAN stretched in the electrostatic field, lattice of Sn distorted. After electrostatic spinning, the XRD diffraction peaks of Sn slightly offset than the standard peaks.

Layer-by-Layer (LbL) assembly technique to prepare hollow microcapsules has broad prospects in textile applications. Poly(styrene sulfonate) (PSS) doped (PSS) calcium carbonate (CaCO3) particles was employed as a template, poly(allylamine hydrochloride) (PAH) and PSS were alternately deposited on the template. The influence of PSS content on the template size and morphology and the loading efficiency of microcapsules were investigated. SEM and TEM were used to observe the morphology and hollow structure of microcapsules; thermal gravimetric analysis (TGA) and UV-vis spectrophotometer were used to characterize the nature of microcapsules. The results showed that the PSS-doped CaCO3 particles are all spherical and the higher concentration of PSS leads to smaller CaCO3 particles size, the PSS amount in CaCO3 particles is 2.73% ~ 5.12%, PSS trapped inside the microcapsules has no effect on its morphology and structure, vacuum drying is better than hot air drying, the resulting microcapsules have a deposition effect for RhB.

A new kind of compound hernia patches made of PP and PVDF are prepared. The steps are as follows. First, PP surface is modified by plasma to increase the surface hydrophilia，then it is attached to electrospun PVDF microfiber by fluoroelastomer . As the results show: In helium atmosphere, the hydrophilic property of PP fabric surface is improved by plasma modification. After treated by plasma, oxygen content and hydrophilia of PP surface are increased while carbon content is decreased tested by XPS. The best parameters are 150W and 2mins. When PP and PVDF compound, the breaking strength is increased, but the elongation at break and thickness essentially is unchanged; The water flux of compound patches is 11.73mL/min , which means the patches are satisfied with normal transmission of body fluids; From the perspective of dimensional stability to say, compound hernia patches are not shrunk in the water with the temperature lower than 50℃, so it is safe for human.

Polyurethane(PU) coated fabric is a kind of functional fabric which has waterproof and moisture permeability, it is widely used to produce the outdoor sports clothing. Using the adhesive interlining, can increase fabrics’ bending rigidity, and thus improve fabrics’ stiffness and formability. Because the PU coating fabric itself has special function of waterproof and moisture permeability, so improper using of adhesive can affect the original function. Eight PU coated fabrics and six adhesive interlinings were selected in this article for fusing, and then tested the basic compatibility indicators of compound fabric, including peeling strength, heating shrinkage, washing shrinkage, washing appearance rating，as well as the changes in water vapor permeability and water repellency, thus to study the compatibility of PU coated fabric and adhesive interlining. It was found that，the kinds of adhesive is the main factor affecting the peeling strength. The thickness and gram weight of adhesive interlining can influence the shrinkage of compound fabrics. The thickness，gram weight and the amount of adhesive influence the thickness and porosity of compound fabrics，thus decrease the water vapor permeability. Adhesive interlining does not much effect the washing appearance rating and water repellency of compound fabrics.

Damage analysis of wool fibers from Small River Cemetery, based on morphology observation of wool fibers including cross-sectional and longitudinal appearance using OM and SEM, can provide scientific bases for conservation, including consolidation and cleaning. Morphology observation suggests that most of the textiles from Small River Cemetery are wool fibers, and the damage degree has significant difference, especially between textiles unearthed from the First and the Fifth Layer due to the buried date and environment. The contaminants sampled from polluted textiles were analyzed by SEM-EDS showing that chloride is the major constituent and found widely in the damaged items. So presumably Chloride is the principal contributor to the damage process of wool fiber.

It was investigated based on conductivities of reactive dyes solution in different conditions,including concentration of the reactive dyes, medium temperature and additives. Results showed that the conductivity of reactive dye solution was directly proportional to the dye concentration and medium temperature. A certain critical range was existed during the change of conductivity which the concentration dye of solution was 30 - 40 mmol/L and the temperature was about 50oC. The change rate of conductivity was different in or out of the range that mainly due to the aggregation of dyes leading to the inhibition of ionization in the condition of high concentration. It was probably raising the temperature was conducive to the disaggregation. The conductvities would decreasced when adding additives such as sodium sulfate todye solution becauce of common ion effect lead to the aggregation of dyes exacerbated. Howerver the conductivity of dye solution was increased when the concentration of sodium sulfate was less than 3 g/L. auxiliaries such as anionic surfactant had significant effect on improving the stability of dye solution at 50 oC.

The dyeing property of modified and unmodified cotton fabric were investigated by testing the absorption spectroscopy of hydrolyzed and un-hydrolyzed active dye solution and the color indexes (L﹡, a﹡, b﹡, c﹡values and K/S value) of the dyed fabrics. It was found that the differences of the UV-Vis absorption spectroscopy of dye solution between hydrolyzation and un-hydrolyzation were very large and the colour of dye solution was light when the active dye was hydrolyzed. The uptake and fixation of the dye, and the colour and K/S valu of the dyed fabric could be influenced by the the hydrolyzation of dye. The dyeing property of cotton fabric could be improved when the fabrics were modified with reactive and non-reactive cationic modifiers. The uptake and fixation of the active dye and hydrolyzed active dye on the cotton fabric which was treated with ractive modifier were improved, especially the fixation.

To discuss the influence of air Suction Slots on the fiber condensing effect , the numerical simulations of the flow distribution in complete condensing spinning system is given by using Fluent software. Corresponding simulation results of airflow distributions in condensing area with three different air Suction Slots are obtained. The results showed that the shape of the suction slot have a great impact on the airflow distribution in condensing zone. The long and short oblique grooves have better condensing effect in the entire condensing area, but they may have negative effect on spun yarn evenness; the Z-axis velocity distribution of long oblique groove can weaken the agglomeration effect. The straight groove may spread the sliver again in the median space. Finally, the theatrical results obtained are illustrated by experiments.
