Current advances on sea-island microfiber nonwoven materials preparation technology and its applications: a review

AbstractWith the increasing textile industry demand for personalized fiber product, leading to the development and application of new fiber, sea-island microfiber become one of the representative new textile materials. Recently, the sea-island microfiber received extensive attention of researchers as a new composite fiber in high technology and high added value. In order to have a comprehensive understanding of the development of sea-island microfiber nonwovens at present, based on the development of sea-island microfiber nonwovens, the paper focused on the development of preparation technology-conjugate spinning and compound spinning, and the melt spinning. Based on the characteristics of sea-island microfiber nonwovens, the applications of the products in the fields of fashion fabrics, microfiber leather, filtration materials, high-performance cleaning cloth and biomedical materials are comprehensively introduced, and the future research orientations of the products are prospected.Keywords: sea-islandmicrofibernonwoven materialscompound spinningmelt spinning Disclosure statementThe authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.Additional informationFundingThe authors thank the Shandong Provincial Key Research and Development Program (Major Scientific and Technological Innovation Project) [2021CXGC011001], Huafon Microfibre (Jiangsu) Co.
