Due to the poor healing ability of anterior cruciate ligaments (ACL), surgical interventions with graft materials are often needed to reconstruct the knee joint. Electrospinning is widely utilized to manufacture highly aligned fibrous materials. When cultured on such substrates, ligament fibroblasts are known to exhibit elongation and enhanced collagen production [1, 2]. Poly-L-lactic-acid (PLLA) is a popular biocompatible material with high mechanical strength, and is most often used in electrospinning with chloroform as solvent. Hexafluoropropanol (HFP), another solvent, generates more uniform and consistent electrospun PLLA fibers. In this study, we investigated the effects of electrospun PLLA fiber scaffolds using different solvent on ligament tissue engineering. PLLA fibers electrospun with chloroform or HFP were compared for their structure and mechanical characteristics. We also investigated their effects on ligament cell morphology and proliferation. Further analysis of composite fiber bilayers were also performed [3].

In the dielectric heating by using microwave, both the interior and exterior of fiber materials can be evenly heated simultaneously. Especially, in case of heating the material of low thermal conduction by normal furnaces, thermal loss is great and it takes long time to finish the required treatment. However, if microwave is applied to fibrous materials, it can be treated rapidly. Also, application of microwave system has the results of remarkably enhancing productivity and improving working environment owing to no air pollution. Thus, in this study, the bonded polypropylene (PP) fibers and PP/PET nonwovens have prepared by dielectric heating with various organic solvents, and their morphological structures and debonding force have investigated with different treatment time.

Dye wastewater is one of the most important problems to be faced and solved in wastewater treatment. However, the treatment cannot be single and simple adsorption due to the complexity of dye species. In this work, we prepared novel composite fiber adsorbent materials consisting of ε-polycaprolactone (PCL) and beta-cyclodextrin-based polymer (PCD) by electrospinning. The morphological and spectral characterization demonstrated the successful preparation of a series of composite fibers with different mass ratios. The obtained fiber materials have demonstrated remarkable selective adsorption for MB and 4-aminoazobenzene solutions. The addition of a PCD component in composite fibers enhanced the mechanical strength of membranes and changed the adsorption uptake due to the cavity molecular structure via host–guest interaction. The dye removal efficiency could reach 24.1 mg/g towards 4-aminoazobenzene. Due to the admirable stability and selectivity adsorption process, the present prepared beta-cyclodextrin-based composite fibers have demonstrated potential large-scale applications in dye uptake and wastewater treatment.

By deeply analyzing and studying the physical and chemical properties of Lueyang’s basalt fiber, its characteristics such as the chemical components, the crystallization’s upper limit temperature and lower limit temperature during the melting process, and the the viscosity and temperature change during melting process are verified to provide theoretical bases for the industrial production of a new type composite materials, and meanwhile to offer grounds for the development of a new generation of composite fiber materials.
