The influence of process parameters including punch frequency, needle penetration depth and punch times on the fiber distribution and straight segment fiber length of needle punched nonwovens was investigated using the Hough transform method. The results show that punch frequency and punch times have more significant influence on the samples than needle penetration depth. When combining the experimental results with image analysis, the optimum process parameters to prepare needle punched nonwovens based on preoxidized polyacrylonitrile were obtained. © 2017 The Royal Society of Chemistry.

The effects of five layered double hydroxides (LDHs) with different zinc ratio on the physical and rheological properties, chemical components, and anti-UV aging performance of asphalt were evaluated. Results show that LDHs improve the deformation resistance of asphalt at high temperature. After UV aging, LDH-modified asphalts show the smaller changes of physical and rheological properties and chemical components in comparison with asphalt, indicating the improved UV aging resistance. By comparison, the LDHs with higher ratio of zinc in the layers have the more outstanding UV reflection ability, leading to a beneficial effect in improving UV aging resistance of asphalt. © 2017 Taylor & Francis Group, LLC.

A new kind of sandwiched composite membrane (SCM) for lithium-ion batteries is prepared by depositing zirconia microparticle between two layers of electrospun poly (vinylidene fluoride-co-hexafluoropropylene) (PVdF-HFP) nanofibers by electrostatic spray deposition. The thermal shrinkage, electrochemical properties of the separator, and cycle performance for batteries with the SCM were investigated. The results show that the SCM has a high electrolyte uptake and easily absorbs electrolyte to form gelled polymer electrolytes (GPEs). The SCM GPEs have a high ionic conductivity of up to 2.06×10-3 S cm-1 at room temperature and show a high electrochemical stability potential of 5.4 V. With LiCoCO2 as cathode, the cell with SCM GPEs exhibits a high initial discharge capacity of 149.7 mAh g-1. © 2016 by ASME.

This paper investigated the ageing behaviour of bitumen modified with organically modified layered double hydroxides (LDH). Two organo-LDHs (OLDHs) intercalated by different UV absorbents, 2-hydroxybenzoic acid (HBA) and 2-hydroxy-4-methoxybenzo- phenone-5-sulfonic acid, were employed to modify one virgin bitumen using a laboratory high-shear mixer, for comparison purposes, a standard LDH was also included as a binder modifier in the experimental investigation. The rolling thin film oven test and UV exposure test were conducted to simulate the short-term and UV ageing of bitumen, respectively, and then the ageing performance of LDH and OLDH modified bitumens was evaluated by analysing the physical and rheological properties and chemical composition. The results showed that OLDH modified bitumens exhibited improved short-term ageing resistance due to the barrier property of layered OLDH to the penetration of oxygen and loss of light components. With respect to the UV ageing, OLDH modified bitumens were found to be less susceptible to UV radiation because of the improved compatibility with bitumen and UV shield effect of OLDH in comparison with LDH. Chemical composition analysis indicated an increase in the concentration of polar fractions resulting from the generation of oxygen-containing functional groups during ageing, leading to an increase of stiffness of bitumen, the increment of polar fraction of OLDH modified bitumens is smaller than that of LDH modified bitumen, exhibiting less ageing degree. © 2017 Informa UK Limited, trading as Taylor & Francis Group

Wet fabric bothers everyone as it sticks to the skin, hinders body movement and brings discomfort and awkwardness on many occasions. Much has to be done to evaluate this adhesion of a wet fabric to human skin for minimizing the discomfort resulting from this phenomenon. In this study, an improved measurement is developed to test and distinguish the adhesion forces of different materials under controlled conditions. A new and improved theoretical model is proposed to estimate the adhesion force based on the gravity of the liquid bridge that formed beneath the fabric. The theoretical values are reasonably consistent with the experimental results. A potential solution is also proposed for reducing the volume of the liquid bridge in designing a less adhesive fabric by constructing hydrophobic protrusions to the fabric surface. © 2016, © The Author(s) 2016.

This work studies the identification of textile fiber components using ThermoGravimetric Analysis (TGA). Optimal conditions for TGA in the identification of the fiber components were investigated. Under the optimal conditions, the feature library of thermal stability of both conventional fiber and high-performance fiber has been established. The results indicated that TGA is suitable for the identification of textile fiber components, in particular for high performance fiber. © 2016 Taylor & Francis Group, London.

The garment pressure comfort sensation was studied in the paper. The garment pressure comfort threshold was defined and calculated according to staircase method of psychophysics. In experiment, 10 subjects were employed in sensory tests and pressure measurements. A novel stretchable compressive belt was designed and developed, which was used to control the pressure applied on separate body parts by its extension and intention, and the subjects judgment and pressure monitor were recorded in times. Finally, the comfort thresholds at 13 separate body parts were investigated. This study provided proper comfort pressure range to human body for developing compression wear. © Springer International Publishing AG 2018.

In this paper, filter bag of polyphenylene sulfide (PPS) needle punched nonwoven for environment protection was investigated. The results showed that air permeability of sample was linear rise with the increase of the pressure drop. During the testing process, the residual pressure drop rose with the increase of cycles because of test dust attaching on the surface of the filter. The PM2.5 filtration efficiency was obtained of 99.854%, which was smaller than the dust filtration efficiency of 99.971% because of the fine particles taking larger proportion of the dust through the sample. Results show that this method of evaluating the PM2.5 filtration property is feasible. © Published under licence by IOP Publishing Ltd.

Electrospun membrane filters used to remove particles from hot gases were highly desired to meet the requirement of application in high temperature. Polyimide is a kind of high performance polymer, especially for excellent thermal stability and chemical resistance. In this paper, the polyimide precursor poly(amic acid) (PAA) was synthesized from 3,3’,4,4’-oxydiphthalic anhydride (ODPA) and 4,4’-methylenedianiline (MDA), the polyimide (PI) ultrathin fiber membrane was fabricated by electrospinning and followed by thermal imidization. Scanning electron microscope (SEM), infrared spectrometry (IR), and thermogravimetric analysis (TGA) were used for the characterizations of the polyimide ultrathin fiber Membrane, the tests show that the diameter of ultrathin fiber is uniform with an average size of around 400nm and the membrane is thermally stable at a high temperature of 500℃. © (2014) Trans Tech Publications, Switzerland.
