| Nowadays, as the pace of life increasing with technology, the requirements of the textiles have a higher standard, various functional textiles arises at this historic moment. Among them, the phase change temperature-regulating fiber as a new type of functional fiber has successfully attracted wide concern in textile research industry. Textile within phase change fiber inside, can achieve the temperature-regulating function through absorpting and releasing energy.The mode of phase change textile is very different from traditional fabric which depend on wearing more cloth to keep warm. In addition, from the development trend of modern textile, the use of a variety of fibers as component of the fabric become more and more. Different fiber has its particular advantages or disadvantages, the comprehensive performance of fabrics can be improved through blending of fibers. Making blended yarns and fabrics using Outlast viscose fiber, Outlast acrylic fiber, cotton fiber, mercerized wool as materials, analyse the relationship between the blended ratio and the comprehensive performance of yarns and fabrics, and compare the difference between the two types of Outlast fiber and their final products.The research is significant for the functional textile development.In this research, we produced a series of Outlast viscose, Outlast acrylic/cotton/mercerized wool blended yarns and blended fabrics. In this paper, the effect on the properties of temperature-regulating and wearing by different Outlast blended yarns and fabrics is mainly researched. And we established comprehensive performance of Outlast viscose and Outlast acrylic evaluating model. This paper mainly accomplished this content as following:(1)Compare the differences on performance between Outlast viscose fiber and Outlast acrylic through test testing items. According to the various components of the fiber such as cotton fiber and mercerized wool, determine the blended ratio of yarns, formulate spinning process and,make blended yarn sample.(2)Test evenness,hairiness and breaking strength of temperature-regulating yarns by different blending ratio. Analyse the relationship between blending ratio and the yarns’ performance. Compare the difference between Outlast viscose and Outlast acrylic blended yarns.(3)Using STOLL electronic flat knitting machines woven13kinds of fabric.Test the temperature-regulating performance, tensile properties, soft permeability, air permeability, moisture permeability, dimensional stability and abrasion resistance of Outlast viscose and Outlast acrylic blended fabrics.Make correlation analysis and test of significance about the relationship between them.(4)Analyse comprehensive performance of Outlast viscose and Outlast acrylic blended fabrics through the fuzzy mathematics method.Choose fabrics that comprehensive performance are superior.Through testing and analysis, the result shows that Outlast viscose and Outlast acrylic fiber both have obvious temperature-regulating effect. In the heating and cooling process,Outlast viscose’s heat enthalpy value were11.290J/g and11.050J/g, and Outlast acrylic’s were6.981J/g and7.467J/g.Outlast viscose blended yarns’ evenness and hairiness properties are better than the Outlast acrylic blended yarns’, but breaking strength is lower. Both in the heating and cooling process, there is a significant linear relationship between the blended ratio and heat enthalpy value of Outlast viscose or Outlast acrylic blended yarns.There a significant correlation between Outlast fiber content and Outlast blended fabrics’ properties such as thermal range, heat enthalpy value, breaking strength, elongation at break, air permeability, wicking height, shrinkage, wear weight loss rate. The results of the comprehensive evaluation of Outlast viscose blended fabrics are superior than Outlast acrylic’s in general. And the more Outlast viscose the fabric contains, the better comprehensive performance it is. |
