Effect of Fiber Configuration on Favorable Rating of Mixed Colour Waste Textiles in Recycling

摘要

There are few effective recycling systems for waste textiles because the material specifications are complex and mixed waste textiles are not easily separable. To improve this situation, we proposed the "Colour Recycle System", which separates waste textiles by colour prior to recycling. Previously, we discussed a separation standard for shoddy of recycling materials and optimizing the colour combination in waste textiles collection. The proposed standard was based on the favorable ratings in a sensitive analysis. However, the optimum separation standard will also depend on the configuration of the fiber assembly. Therefore, this paper investigates the effect of fiber configuration such as grain and yarn on the favorable ratings. The threshold value for highly favorable ratings was identified as 80-105° interior angle on the Munsell color circle, regardless of configuration.
