Abstract

Microfiber is unique in drape, lustre, texture, and appearance. The market is gradually expanding not only for high-grade fabrics with soft touch like artificial suede but also for high-performance breathable and waterproof fabrics, highly hygroscopic knitted fabrics, cleaners, filters and dustproof clothing as well as industrial applications. Particularly PVDF, which is used as a waterproof material for mobile phones, is made of polyvinylidene fluoride [CH2- CF2]n. It has a melting point of 170oC and a thermal decomposition temperature of 300oC or higher with thermoplastic resin having thermal resistance obtained by polymerization of vinylidene fluoride (1, 1-difluoroethene) with PVF2 or PVDF, so that injection and extrusion, and various moulding methods of compression are applicable. This polymer is a type of fluorocarbon resin, which is excellent in mechanical properties and can be made into a highly crystalline resin. However, the research and development of dyeability is not necessary because there is no need for a product, and information is also lacking. This study selected optimized dyeing conditions of PVDF using real-time dyeing behaviour monitoring system. The real-time dyeing behaviour monitoring system consists of a laboratory dyeing machine and a measuring device, and a real-time analysis program for dyeing behaviour. As a result of PVDF staining, it was possible to dye with various colours.
