| In the summer and autumn seasons,ultraviolet radiation on the human body is relatively strong,easily causing skin damage,and the temperature difference between day and night is large,making the human body feel uncomfortable and prone to diseases such as colds and fever,which can have a significant impact on human health.Fabrics that have both ultraviolet resistance and far infrared function can absorb and reflect ultraviolet rays.At low temperatures,they can also raise their own temperature by absorbing far infrared rays,solve the problem of local skin cooling,accelerate human metabolism,and achieve the goals of warmth and health preservation.Therefore,researching and developing ultraviolet resistant far infrared textiles is of great significance.As an excellent textile material,graphene functional yarn has not only excellent physical properties,but also ultraviolet resistance and far infrared function.Based on this,this study focuses on graphene fibers and explores the effects of different graphene fiber content and fabric structure in weft yarns on the UV resistance,far-infrared function,and wearability of graphene fiber interwoven fabrics.This provides theoretical support for the design and development of ultraviolet resistant far infrared graphene fiber interwoven fabrics.The main research content is as follows:(1)Through testing and analyzing the surface morphology and mechanical properties of fibers,the research shows that there are obvious grooves on the longitudinal surface of graphene polyester filament,making its moisture regain 2.31%higher than that of ordinary polyester;The tensile breaking strength of graphene polyester filament is higher than that of graphene acrylic staple yarn,while the elongation is lower than that of graphene acrylic staple yarn.(2)According to the required wearability of clothing fabric products in the summer and autumn seasons,fabric samples are tested and analyzed,the research shows that the higher the content of graphene polyester filament in the weft yarn,the better the anti fuzzing and pilling,moisture permeability,and weft wrinkle recovery of the fabric sample,and the worse the air permeability,while the tensile fracture property has no significant change;The higher the content of graphene acrylic staple yarn in the weft yarn,the better the moisture permeability and weft wrinkle recovery of the fabric sample,the worse the pilling resistance and air permeability,while the tensile fracture property has no significant change;Among different weaves,plain weave fabrics have the best anti fuzzing and pilling and tensile fracture,but their air permeability,moisture permeability,and weft crease recovery are the worst.Eight satin fabrics have the best air permeability,moisture permeability,and weft crease recovery,but their anti fuzzing and pilling and tensile fracture are the worst.(3)Through testing and analyzing the ultraviolet resistance and far infrared function of graphene fiber interwoven fabric,the research shows that:With the increase of the content of graphene polyester filament or graphene acrylic staple yarn in the weft yarn,the anti ultraviolet and far infrared functions of the fabric samples gradually increase.When the content of graphene polyester filament in the weft yarn reaches 100%,the ultraviolet resistance of the graphene polyester sample is the best,with UPF of 1433.56 and T(UVA)AV of 0.32%.When the content of graphene acrylic staple yarn reaches 100%,the fabric sample has the best far infrared performance,with far infrared emissivity of 0.949 and far infrared radiation temperature rise of 2.13℃.Among different fabrics,eight satin fabrics have the best ultraviolet resistance,but their far infrared function is the worst.Honeycomb fabrics have the best far infrared function,but their ultraviolet resistance is the worst.(4)In order to better reflect the ultraviolet resistance,far infrared function,and wearability of the fabric,a fuzzy comprehensive evaluation analysis is conducted on the test results,the research shows that the optimal sample scheme for the comprehensive ultraviolet and far infrared resistance of fabrics is:when the content of graphene polyester filament or graphene acrylic staple yarn in the weft yarn is 80%,and the weave adopts eight satin patterns.(5)In the end,based on market trends and people’s various needs for clothing,software such as Zhejiang University Jingwei JCAD is used to design color patterns and organizational structures for graphene fiber interwoven fabric products.Six different styles of graphene fiber interwoven fabric products are developed using large jacquard looms,to meet the demand of people for ultraviolet resistance and far infrared clothing fabric products. |
