Improving Washable Woolen Fabric By Using Layer-By-Layer Coating

Abstract

There are many different methods used in the industry to improve the antifelting and shrinkproof properties of wool blended fabrics. In the study, Layer-by-Layer technique used to improve the antifelting and shrinkproof properties of wool blended fabrics as an effective nanofabrication method according to the literature. Different polyelectrolytes and nano-polyurethane were applied on ecru and light, medium, dark color dyed suit wool blended fabrics by using Layer-by-Layer method. After the application fabrics, relaxation and felting shrinkage, breaking and tear strength tests and color/strength measurements were performed. Besides, the effect of squeezing roller velocity and pressure on the fabrics were evaluated. It is ensured that the relaxation and felting shrinkage values are within ± 3%. It has been observed that soft handle fabrics are obtained after coating without any negative effect on the fabric. In addition, SEM-EDX and FTIR-ATR analysis were performed to determine the surface properties of the fabrics and bond characterization of the films.
