Drug therapy towards tumours often causes adverse effects because of their non-specific nature. membrane-coated technology and membrane-coated nanoparticles provide an advanced and promising platform of targeted and safe delivery. By camouflaging the nanoparticles with natural derived or artificially modified cell membranes, the nano-payloads are bestowed with properties from cell membranes such as longer circulation, tumour or inflammation-targeting, immune stimulation, augmenting the performance of traditional therapeutics. In this review, we review the development of membrane coating technology, and summarise the technical details, physicochemical properties, and research status of membrane-coated nanoparticles from different sources in tumour treatment. Finally, we also look forward to the prospects and challenges of transforming membrane coating technology from experiment into clinical use. Taken together, membrane-coated nanoparticles are bound to become one of the most potential anti-tumour strategies in the future. © 2024, Chinese medical multimedia Press Co Ltd.

Predicting the Stitch Density of Finished Fabrics Using weft Blended Grey Knit Fabrics

引用

Journal of Textile Science and Technology 2024年第3期10卷 51-63页

作者： Kazi md. Elias mohammad Obaidur Rahman h. m. Zakir hossain Department of Physics Jahangirnagar University Savar Bangladesh Jute Textile wing Bangladesh Jute Research Institute Dhaka Bangladesh

Stitch density is one of the critical quality parameters of knit fabrics. This parameter is closely related to other physical quality parameters like fabric weight, fabric tightness factor, fiber types, blend ratio, yarn diameter and linear density, and fabric structure. Selecting stitch density (wales per inch, course per inch) is essential to getting the appropriate fabric weight and desired quality. Usually, no rules or assumptions exist to get the desired stitch density in the finished fabric stage. Fifteen types of blended knit fabrics were prepared to conduct the study. The varying percentages of cotton, polyester, and elastane are incorporated in the blends. Regression analysis and regression ANOVA tests were done to predict the stitch density of finished fabrics. A suitable regression equation is established to get the desired results. The study also found that the stitch density value in the finished stage fabric decreases by approximately 15% compared to the stitch density in the grey fabric stage. This study will help the fabric manufacturers get the finished fabric stitch density in advance by utilizing the grey fabric stitch density data set. The author expects this research to benefit the knitting and dyeing industry, new researchers, and advanced researchers.
