Research on Coefficients of Inter-Yarn Friction in Sateen Fabric with Zno Nanowires by Yarn Pull-Out Model and Test

Abstract

Zinc oxide nanowires are often used to improve the bulletproof performance of fabrics, but determining the coefficients of inter-yarn friction of those fabrics in numerical ballistic model is a challenge. In this article, linear and capstan methods are adopted to obtain the coefficients of inter-yarn friction of two thread density sateen fabrics treated with zinc oxide nanowires. It is found that for both of S-8-ZnO and S-13-ZnO fabrics, the errors of the yarn pull-out force by the linear method are 0.43% and 6.56%, respectively, which are significantly lower than those of the capstan method. The results indicate that the linear method is better for calculating the coefficients of friction of fabrics with ZnO nanowires.
