Research on Dissolvant-Based Infrared Yarn Dyeing Process of Polyacrylonitrile Fiber

Abstract

Cationic dye is a special dye for polyacrylonitrile, but it is very difficult in dying through the core. In practice, the price of special leveling agent for polyacrylonitrile fiber is high, and uniform staining is poor. By mixing a number of organic solvents in the dye bath, we can improve the structure of fibers and its deep-dyed. In this paper, we use n-propanol, isopropanol and benzyl alcohol as organic solvent, by adjusting the pH value and the appropriate temperature, and with special depth and leveling agent for dyeing soaping fastness contrast, to find economically viable process conditions.

Use of Sustainable Energy as a Heating Source to Improve Dyeability and Other Properties of Wool and Polyamide-6 Fabrics with Nano-Silica

“…Fastness properties of the dyed samples were determined according to IsO standard methods. The specific tests were ISO 105-C06 (2010), color fastness to washing; IsO 105-E04:2013, color fastness to perspiration (acid and alkaline); and IsO 105-B02 (2014), color fastness to light and rubbing [24][25][26][27] .…”
