摘要
为了探讨纬纱中石墨烯功能性纱线种类、含量及不同织物组织对石墨烯机织物的抗紫外线性能和远红外性能的影响,文章分别以石墨烯涤纶长丝、石墨烯腈纶短纤纱、普通涤纶长丝和黏胶短纤纱为原料,设计织造了4个系列具有不同织物规格的28种织物试样。对所得28种织物试样分别进行抗紫外线性能和远红外性能测试,并通过模糊综合评判方法对试样相关指标进行评判。结果表明:随着纬纱中石墨烯功能性纱线含量的增加,织物的抗紫外线性能和远红外性能逐渐增强;织物组织越紧密,平均浮长越长,表面越光滑,织物的抗紫外线性能越强;织物表面越粗糙,厚度越厚,织物的远红外性能越好;当纬纱中石墨烯功能性纱线含量达到100%时,组织采用8枚纬缎或5枚纬缎的试样抗紫外线和远红外综合性能达到最优。
In recent years,with the continuous improvement of living standards and the gradual enhancement of people’s health awareness,the demand for health care functional textiles has been increasing gradually,and the development of health care functional textiles has become a hot spot in the development of new textile products.Health care functional textiles can protect people who work outdoors for a long time,reduce the impact of ultraviolet radiation on human health,and promote human blood circulation,improve the circulatory system,enhance metabolism and improve immune functions under the radiation of far infrared.Therefore,the research and development of anti-ultraviolet and far-infrared health care functional fabric is of great significance.As an excellent textile material,graphene functional yarn has not only excellent physical properties,but also ultraviolet-resistant and far-infrared properties,with a good prospect in the development of health care functional textiles.Cellulose from biomass straw was used as raw material for the graphene functional yarn selected in this study,and the method of“group coordination assembly carbon analysis”was adopted to obtain the biomass graphene fiber,which was then combined with polyester and acrylic fibers to produce the graphene functional yarn.In this study,four series of fabric samples from A to D were designed,and all fabric samples were warp spun with polyester.The weft yarns for series A fabric samples were graphene polyester filaments and ordinary polyester filaments.Nine types of fabric samples with a content of graphene polyester filaments ranging from 0 to 100% were designed.The weft yarns of the B series fabric samples were graphene polyester filaments and ordinary polyester filaments,and the content of graphene polyester filaments in the weft yarns was 50%.Six fabric samples with different organizational weaves were designed.The weft yarns of the C series fabric samples were graphene acrylic staple fibers and ordinary viscose staple fibers.Nine fabric samples with a content of graphene acrylic staple fibers in the weft yarns from 0 to 100% were designed.The weft yarns for the D series fabric samples were graphene acrylic staple yarn and ordinary viscose staple yarn.The content of graphene acrylic staple yarn in the weft yarn was 50%.Six fabric samples with different organizational weaves were designed.The article explored the ultraviolet and far-infrared properties of four series of fabric samples.The results showed that with the increase of the content of graphene polyester filament or graphene acrylic staple yarn in the weft yarn,the ultraviolet resistance of the fabric sample gradually increases.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 value of 1433.56 and T(UVA)AV of 0.32%.The fabric weave and weft density have a significant impact on the ultraviolet resistance of fabric samples.Different fabric weaves lead to the difference in tightness,thickness,gram weight and average float length of fabrics.The ultraviolet resistance of 8-weft satin graphene polyester sample is the best,with UPF value of 136.84 and T(UVA)AV of 4.95%.This is due to the larger weft density and tightness of the sample,the longest average float length,fewer warp and weft yarn interlacing points,and less ultraviolet light transmitted through the sample.Therefore,the sample has the best ultraviolet resistance.The ultraviolet resistance of the graphene acrylic honeycomb weave sample is the worst,with UPF value of 17.02 and T(UVA)AV of 9.53%.Because its weft density is smaller,the coverage is smaller,the surface smoothness is the lowest,the ultraviolet reflection ability is the worst,the ultraviolet resistance of the sample is the worst.With the increase of the content of graphene polyester filament or graphene acrylic staple yarn in the weft yarn,the far-infrared performance of fabric samples gradually increases.When the content of graphene acrylic staple yarn reaches 100%,the far-infrared performance of fabric sample is the best,the far-infrared emissivity reaches 0.949%,and the far-infrared irradiation temperature rises to 2.13℃.The far-infrared performance of the fabrics is also related to the surface morphology of the fabric.The far-infrared performance of the graphene acrylic fiber sample is the best,the far-infrared emissivity is 0.954%,and the far-infrared temperature raises by 2.03℃,because the thickness of the sample is thicker,the surface is the coarsest,and the reflection ability of the infrared light is weak,leading to the the better far infrared performance of the sample.Through the mathematical method of fuzzy comprehensive evaluation,it is concluded that among the B series fabric samples,8-weft satin graphene polyester sample has the best comprehensive ultraviolet and far-infrared resistance.Among the D series fabric samples,5-weft satin graphene acrylic fiber sample has the best comprehensive ultraviolet and far-infrared resistance.The samples studied in this article are samples with the best comprehensive performance of ultraviolet and far-infrared resistance by adjusting the type and content of graphene functional yarn in the weft yarn and different fabric weaves,providing reference for the subsequent development of graphene health functional textiles.
