Research progress on application of polyurethane elastic fiber fabric in clothing design
This paper reviews the dry spinning process of polyurethane elastic fibers(spandex),methods for improving spandex properties,preparation methods and properties of multifunctional spandex fabrics.Antistatic spandex can be prepared by adding organic titanium antistatic agents and other additives to polyurethane solution through dry spinning.The spinning solution obtained by curing the solution containing polyurethane-urea and adding anti yellowing additives can be used to prepare anti yellowing spandex through dry spinning.Core-spun yarn is prepared by using spandex filament as the core yarn and cotton yarn mixed with modified polyacrylonitrile fiber as the outer yarn.The honeycomb tissue fabric woven performs excellently in moisture absorption and heat generation.Amino groups are grafted onto the surface of spandex with solution of 3-aminopropyltriethoxysilane,and then immersed in carboxylated multi walled carbon nanotube dispersion to obtain carbon nanotube coated spandex,which is then spun into knitted fabric and used as a wearable strain sensor for real-time healthcare monitoring.
