Authors: Zhu Rui Tian , Yan Yu Rong , Zhao Yao Ming , Zhang Peng , Pan Wei
Published: September 2011

Gelatin is a kind of biopolymer obtained from animals and its fiber has been used as one of biocompatible dressings and sealants for many years. Electrospun gelatin nanofiber got more attention for its high specific surface area. Low toxicity gelatin nanofiber mats can be obtained by using water as the solvent in electrospinning process, but the fiber diameter below 150 nm is not easy to control and lots of beads were formed in the mats for low concentration solutions. In this study, sodium dodecyl sulfate (SDS) and ethanol were used to improve the electrospinnability of the gelatin solution with the concentration of 13 wt %. Experimental result revealed that SDS and ethanol reduced the surface tension of gelatin solution, meanwhile increased the conductivity and the viscosity. With the ratio between water and ethanol of 95 to 5, and SDS content varied from 0.3 wt % to 0.8 wt %, beads along the gelatin fibers vanished. Smooth and uniform gelatin fibers with fibers’ diameter around 110 nm were obtained.

Authors: Liu Han Wu , Pu Gui Bing , Du Yun Hui , Zhang Peng
Published: September 2011

By using the geometry modeling software Pro/E, the three-dimensional model of hydraulic shield support has been built. Considering of the loading conditions and displacement constraints which the hydraulic shield support suffers from under the actual working conditions, the static strength and fatigue strength of the hydraulic shield support were analyzed by FEM when they were in two different typical working conditions of the support height, and the weakest part which was discovered in the analysis was improved in its structure. The study results showed that the designed hydraulic shield support could meet the requests of the static strength and fatigue strength. The column of the hydraulic shield support and the ear plate which locates in the connection area of the column and the push beam are the weakest parts. The counterforce given by the ground mainly focuses on the mid-back position of the hydraulic shield support, which meets the requirements of saving labor when they were removed. In the Finite Element Analysis when the reinforcement ribs were added to the ear plate, we found that the maximum equivalent stress is reduced by 150 MPa and the fatigue life coefficient is reduced markedly as well. The possibility of the fatigue breakage was decreased largely after the structure was modified and the service life of the hydraulic shield support was improved. These prove that the improvement of the hydraulic shield support structure is reasonable and feasible.

Published: September 2011

In recent decades, different concepts in quality management in textile industries have been introduced. Quality is a highly significant concept and also is the most basic challenge for textile industries. What we called controlling in the past, now has been replaced by “quality control”. Among these strategies, production and noble thought in order to recognize and remove not valuable resources on one hand, and six sigma in order to recognize and remove error elements in the process on the other hand, have developed the textile factories. Six sigma and noble methodology are two very strong strategies in for textile companies to reach success and have high quality products. Noble methodology causes a cut in the expenses through optimizing the process whereas six sigma is related to the customers’ expectations or needs. It also improves quality through measuring and controlling the deficits. This study is an attempt to improve textile products through two views: six sigma and noble methodology.

Authors: Zhu Cheng Yan , Ying Wei Wei , Zhang Hui Fang
Published: September 2011

The single-layered needle-punched nonwovens and multi-layered needle-punched composite fabrics were prepared in this paper, which were made by polyester fibers under proper parameters. The filtration performance of fabrics was evaluated through the analyses of filtration efficiency, filtration resistance, pore sizes, air permeability and porosity. The mechanical properties of fabrics were also studied. The results show that the filtration efficiency of multi-layered needle-punched composite fabrics increases by about 20% and the filtration resistance drops by about 200% when compared with those of single-layered needle-punched nonwovens. The tensile strength of multi-layered needle-punched composite fabrics goes up obviously. However, the difference between horizontal and vertical strength is visible and the stability is also poor. Compared to the composite fabrics with woven textiles, the composite fabrics with knitted textiles are better in filtration performance, but worse in mechanical properties.

Published: September 2011

This work focused on the release behaviour and antibacterial efficiency of Polypropylene (PP)-based and Polyethylene terephthalate (PET)-based hollow fiber with silver particles incorporated (shortened as PP/Ag and PET/Ag). Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were used to investigate the antibacterial capability of Ag/PP and Ag/PET with the method of antibacterial kinetics experiments. The antibacterial results demonstrated that all samples had an excellent antibacterial property against E. coli and S. aureus, and the antibacterial efficiency of Ag/PET was greater than that of Ag/PP. Furthermore, Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AS) was applied to detect the release behaviour of silver ions from Ag/PP and Ag/PET. And the results showed that in the same weight of silver incorporated in hollow fibers, the release behaviour of silver ions from Ag/PET was more than that from Ag/PP , which may be explained by the moisture absorption of the PP and PET. From the results of antibacterial and release experiments, it could be concluded that the release behaviour of silver ions from the fibers, which was depended on the moisture absorption of the matrix, was an important parameter to affect the antibacterial efficiency.

Based on these results a temperature control process for cutinase was developed to improve cotton waxes removal: Firstly cotton fabric was treated by cutinase at 70°C for 10 min, and then the treatment temperature was switched to 55°C and kept this temperature till to the end of the treatment. As a result, maximal cotton waxes removal of 67.69% for cutinase and 75.37% for combined enzymes (cutinase with pectinase and cellulase) were achieved, which was 17.96% and 13.88% higher than that of treatment at 55°C for cutinase and combined enzymes respectively. Moreover, the mechanism involved in enhancing cotton waxes removal in temperature control process was also discussed.

Effect of Wet-Heat and Dry-Heat Processing on Mechanical Properties of PLA Fibers
Authors: Zou Han Tao , Gan Hou Lei , Wang Luo Xin , Yi Chang Hai
Published: September 2011

The influence of temperature and time of dry-heat and wet-heat processing on the tensile property of the PLA fibers was investigated. The results indicate that as the temperature and time increase, the tensile strength of the fibers gradually decreases. When the temperature is above 100 °C or time over 20 minutes, the dry-heat treatment results in significant decrease on tensile property of the fibers. In the wet-heat treatment, the strength of PLA fibers is influenced by the treatment time, temperature and pH value. The acid-resistant property of PLA fibers is better than the resistance to alkali. Under weak acid condition, the performance of PLA fiber is relatively steady. But the fibers under alkali condition over 100°C are hydrolyzed into pieces and the force losses nearly completely. Moreover, the oxidant and reducing agent also impart the tensile property of PLA fibers. The concentration of H2O2 no more than 5g/L is appropriate, whereas the lower concentration of Na2S2O4 is proper.

Fuzzing and pilling of fabrics, which is one of the factors that affect fabric appearance and wear behaviour, has plagued the people for a long time. With the development of living standard, people have higher and higher requirements on the properties of apparel. Several methods can be used for testing the fuzzing and pilling performance of fabric, and different methods often have different results. Using circular locus method and pilling box method on the four kinds of fabrics at the same time, conduct experimental data processing, compare the advantage and disadvantage of two methods and obtain the principle of selection of them. There are many factors that cause fuzzing and pilling, among which the overall covering factor is a significant one. Through the testing for four different kinds of cotton-wool mixed fabrics, with different warp density and different weft density, establish the relationship between the number of pills and the overall covering factor, and obtain the critical covering factor according to the one factor nonlinear regression equation.

The MWNTs-OH/PET composite fibers were prepared by the masterbatch melt blending spinning drawing one-step process (FDY), and the structure and properties of different contents of MWNTs-OH of the PET FDY fiber were studied. The results showed that the interaction between MWNTs-OH and PET matrix was enhanced after the modification of terephthalic acid (TPA), resulting in the improved interface compatibility. Also, the crystallinity of the composite fibers was raised 7% after the addition of modified MWNTs-OH. The fracture strength of composite fibers had firstly increased and then decreased with increasing of the content of MWNTs-OH, the strength of the composite fiber was largely improved by 60.5% with 0.2% (wt) of TPA/MWNTs-OH.

Fabric keyboard is a field of smart textile. It can overcome many disadvantages of conventional keyboard. In order to study the fabric keyboard switch, trapezia structures of two kinds of orifice dimension are designed for example 8 wefts and 16 wefts. Different roots of conductive wires are woven into the down layer of the orifice part for each kind of orifice dimension. 4 and 8 roots of wires are woven for 8 wefts. 4, 8 and 16 roots of wires are woven for 16wefts. Then the immediate regain, connection pressure, connection ratio and contact resistance are tested and analyzed for every kind of fabric keyboard switch. It is concluded that 8 wefts orifice dimension and 8 roots of wires woven into the down layer of the orifice part is a better project. These findings may assist in recommendations regarding the further development of flexible fabric keyboard.

Published: September 2011

Although manufactured nanomaterials have a great many of fantastic functions，the adverse impacts about them have been observed. As a kind of nanomaterial, biomedical films obtained from electrospinning are valued greatly, and the sizes of the diameters in electrospun films plays a fundamental role in enhancing the safety of films. When the diameter of fibers increased to hundreds of nanometers, it will become difficult for fibers to diffuse and infiltrate into human’s body, and then the security of the biomedical films is enhanced greatly. In our work, high viscosity polymer and high viscosity solution are electrospun to increase the diameter of fibers. Besides, melt-eletrospinning is introduced as an alternative candidate for improving the security of biomedical films, especially no poisonous solvent exists.
