Published: February 2021

Abstract
Structural colour has attracted more and more attentions owing to its advantages of non-fading, environment friendly and non-toxic. According to its behaviour with respect to the viewing angle, there are two groups: iridescent (angle-dependent) and nor iridescent (angle-independent). However, many applications in textile and fashion require stable colour which means the colour shows low angle dependent. In this work, 314nm silica nanoparticle was synthesized by using a solvent varying technic which based on Stöber method. Iridescent structurally coloured film was directly self-assembled by gravity sedimentation of silica nanoparticle. Then, film was triturated and redispersed by ultrasonic dispersion process. Low angle-dependent structurally coloured film was then obtained by the redispersed silica nanoparticles. The effect of redispersion time on the structural colours was studied. The result shows that a twenty-minute redispersion gives a less bright but low angle-dependent structural colour film.

Abstract
For exploiting the ecological multifunctional cotton fabric, the citric acid, maleic acid and soybean protein were used to treat the cotton fabric so that the chemical bonding between soybean protein and cotton fabric was formed through the bridging function of multicarboxylic acids. Effects of treating conditions on the weight gain of cotton fabric were analyzed and the optimized process parameters were also obtained. The characterization of infrared spectra showed that the esterification crosslinking occurred between multicarboxylic acids and macromolecules of cotton fiber according to ring-anhydride mechanism, while the soybean protein was combined on cotton fabric with the amido bond by the bridging function of multicarboxylic acids. The breaking strength of soybean protein modified cotton fabric slightly decreased, whereas the anti-ultraviolet property of modified cotton fabric after cactus extract treatment improved remarkably.

Abstract
In order to study the effect of calcium carbonate particles as pore-forming agent on properties of recycled polyethylene terephthalate(PET) masterbatch, pore-forming agent and PET derived from waste bottle were melt-blended and extruded, and then treated with acetic acid solution to obtain recycled PET masterbatch with micro-cavity structure. The influence of content of pore-forming agent and parameters of twin screw extruder for granulation process on the performance of recycled PET melt and masterbatch were analyzed. The results show that the intrinsic viscosity of recycled PET masterbatch is greatly affected by pore-forming agent and the parameters of the twin screw extruder for granulation process. When the mass ratio of polyester bottle flakes to virgin PET is 9:1 and 3 wt% of pore-forming agent added, with the temperature of the barrel 1~6 of the twin-screw extruder is 240°C, 244°C, 244°C, 244°C, 240°C, 240°C, respectively, and 150 r/min of screw speed, the intrinsic viscosity of the recycled PET masterbatch produced by twin screw extruder can reach 0.613 dL/g. The recycled PET masterbatch could be applied to PET fibers spinning. This method provides a new method for improving moisture regain for PET.

Effects of the electric field distribution on electrospun PET fibers properties
Authors: Mu Xiaoqi , Zheng Yuansheng , Xin Binjie 
Published: February 2021

Abstract
Electric field plays a key role in producing required nanofibers in electrospinning. The applied voltage and working distance are the two main factors affects the electric field distribution during the electrospinning process. This work discussed the effects of these two parameters on the fiber fineness and performance in the electrospinning process, and also verified the results of numerical simulation through a series of experiments. The results showed that the larger the voltage applied to the spinneret is, the greater the electric force acting on the fibers is, which leads to a smaller fiber fineness and a preferable hydrophobic performance and strength. On the other hand, as the spinning distance increases, the smaller the force exerted on the fiber is, the larger the diameter is and the weaker hydrophobic performance is.

Abstract
Electrospinning has the advantages of large specific surface area and high porosity, and the nanofibers prepared by it can be widely used in environmental engineering, wound dressing, scaffold materials, biomedicine and other fields. Because gelatin is a biological material with biodegradable and good biocompatibility properties; while poly(L-lactide-co-ε-caprolactone) (PLCL) is a biological material with excellent mechanical properties and good biocompatibility. Therefore, the prepared PLCL/gelatin nanofiber membrane has good biocompatibility, and has minimal repellency to the body during clinical use, and is effective as a scaffold material. This article uses PLCL and gelatin as experimental materials to study the development and optimization of fiber scaffold materials. First introduce the existing tissue engineering scaffold materials, and then describe the basic principles of electrospinning technology. Used 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as solvent to prepare PLCL/GE spinning solution and prepare nanofiber membranes with different total concentrations and different ratios of PLCL to GE, then used the electrospinning process as preparation method to spin nanofiber membranes separately, and the microstructure and hydrophobic performance parameters of the nanofibers were tested and characterized.
