Preparation and study of vitamin E viscose/graphene nylon/silk composite functional fabrics
Mulberry silk is known as the"queen of natural fibers".It is one of the best choices for high-grade textiles.In recent years,the development of functional silk products has no longer focused on the research and development of a single function,but towards the direction of multi-functional integration.Vitamin E is one of the most common active ingredients in skin care products and has a strong antioxidant effect.Vitamin E is coated with microcapsules and added to the spinning solution,and the yarn with vitamin E formed by wet spinning has skin-care function.Graphene is a popular new textile raw material,with excellent mechanical properties,electrical conductivity,far infrared radiation properties,and solar ultraviolet radiation protective properties.To explore the possibility of applying these two functional materials to the preparation of multifunctional textiles,this article aims to explore the effects of the filling ratio of two kinds of functional yarns as well as fabric structure,and to quantitatively and systematically analyze the samples with the best comprehensive performance through mathematical methods.In this study,vitamin E viscose and graphene nylon were selected as weft yarn,and mulberry silk was selected as warp yarn.Antioxidant properties,far infrared radiation properties,solar ultraviolet radiation protective properties and electrostatic propensities were taken as functional objectives,and the filling ratio of the two weft yarns and fabric structure were taken as variables.The DPPH elimination rate,far infrared emissivity,far infrared radiation temperature rise,UPF,T(UVA)AV and HDT were used as measurement indexes for data analysis.Response surface methodology(RSM)was used to establish the model relationship between variables and the expression of functional performance,and analyze the effects of variables.Fuzzy multi-criteria decision method(F-MCDM)was used to comprehensively calculate and evaluate the samples,and the fabric sample with the best comprehensive performance was selected.The results show that the filling ratio of vitamin E viscos and graphene nylon and the fabric structure have effects on the antioxidant properties of the samples,and the influence of the three is pairwisely interactional.With the increase of the content of vitamin E viscose,the antioxidant properties of the fabrics are enhanced.The antioxidant performance in honeycomb weave is the best.With the increase of the content of graphene nylon,the far infrared emissivity and far infrared radiation temperature rise of the fabric are significantly enhanced,and the far infrared performance of honeycomb weave is the best.With the increase of the content of graphene nylon,solar ultraviolet radiation protective properties of the fabrics are generally enhanced.The anti-ultraviolet performance of double damask is the best,and that of the honeycomb weave is the worst.While the filling ratio of two kinds of weft yarns and fabric structure have pairwise interaction effects on UPF values,there is a triple interaction effect on T(UVA)AV.The electrostatic propensities of the samples are only related to the content of vitamin E viscose and graphene nylon in the weft yarns.When the filling yarn contains vitamin E viscos,the electrostatic propensity is significantly improved,but when the vitamin E viscose is reduced to a certain extent,the electrostatic propensities of the sample do not fluctuate and are still excellent.It is found through F-MCDM that when the filling ratio of vitamin E viscose yarn and graphene nylon is 1︰1 and the fabric is double damask,the comprehensive functional performance of the fabric is the best.When the filling ratio is 3︰1 or 1︰3 and the fabric is double damask,the comprehensive functional performance of the fabric is satisfactory.The result has certain reference significance for functional textile production enterprises.
