摩擦纺功能纱线的现状和发展趋势OACSTPCD

In order to better understand the application prospect of friction spinning core-shell structure functional yarn in functional textiles,the development history of friction spinning,the principle of friction spinning,as well as the types and application areas of friction spinning core-shell structure functional yarn were reviewed.The advantages and challenges of sensing yarns,protective yarns and thermal management yarns based on friction spinning technology were emphatically discussed.Finally,the development trend of friction spinning functional yarns was outlooked.It is considered that friction spinning technology has special advantages on the preparation of functional yarns.The contradiction between the difficulty of high-functional raw material spinning and stable yarn formation is solved by friction spinning.The layered structure of friction spinning yarn provides a basis for the structure control of functional yarns.Aimed at the defects of friction spinning functional yarn such as worse strength,lower twisting efficiency,and insufficient interfacial force between fibers,the improvement of yarn mechanical property should be sped up,the twisting efficiency of the yarn should be improved,and the industrialization of friction-spinning functional yarns should be promoted.
