Development and optimisation of waterproof breathable double-sided knitting using a factorial experimental design

This work reports waterproof breathable coated double-sided knitting consisting of cotton and polyester fibres. Two kinds of fabrics (F1 and F2) were tested in this study. They were treated with water-repellent chemicals finishing carried out on the polyester side. The main goal of this paper is to study the application and behaviour of double-sided knitting and the finishing with new chemical product to improve comfort. Optimisation of waterproof breathable property of samples was investigated using factorial experimental design. The combined effects of parameters which can affect treatment on water repellency, air permeability and porosity were then studied and the optimum conditions were determined. Waterproof breathable double-sided knitting was able to be generated. These fabrics are supposed to be used as the shoes lining.
