Kinetic and Diffusional Approach to the Dyeing Behavior of the Polyester PTT

Abstract

The textile fiber made of poly(trimethylene terephthalate) came onto the market a few years ago. This fiber has certain advantages over traditional polyester, especially its greater elasticity and the fact that it can be dyed at lower temperatures. Here we study the dyeing kinetics of this “new” fiber using an azo disperse dye, C.I. Disperse Red 82, observing that the dyeing rate increases with temperature and that dyebath exhaustions only reach acceptable levels at temperatures above 80 °C. In order to quantify and compare the experimental data obtained, three kinetics models have been chosen. To fit results with models, non-linear regression methods have been applied and, to differentiate between early and final stages, two levels of exhaustion have been checked. From results obtained with the Chrastil model, apparent diffusion coefficients and the activation energy of diffusion have been calculated.

Evaluation of the interactions of DNA with the textile dyes Disperse Orange 1 and Disperse Red 1 and their electrolysis products using an electrochemical biosensor

“…These compounds are applied to fibers such as polyester, polyurethane, polyamide, and nylon [3][4][5]. During the dyeing process, the dye molecule undergoes hydrolysis, and the form that was originally insoluble slowly precipitates over the fiber in the disperse form [1].…”

Physical Properties and Wear Comfort of Bio-Fiber-Embedded Yarns and their Knitted Fabrics According to Yarn Structures

“…The mechanical properties of the knitted fabrics were measured using a KES-FB system. The tensile, shear, bending, compression, and surface properties of the knitted fabric specimens were measured with 16 mechanical properties including the fabric weight and thickness [18]. Three tests were conducted for each specimen.…”

“…Recently, PTT has been used for high emotional garment fabrics because of its high elastic property and ecofriendly characteristics; therefore, PTT has been the focus of the textile materials for high functional and eco-friendly fabrics. Liu et al [13], Luo et al [14,15], and Ovejero et al [18] examined PTT filaments and their fabrics. Recently, Kim [11] investigated the physical properties of PTT-and wool-imbedded air vortex yarns and the wear comfort of their knitted fabrics for high emotional garments.…”

Soft-sensing method of color measurement in batch dyeing process of knitted cotton with reactive dyes

“…is the adjustment factor to compensate for the loss because of the occurrence of the association and the hydrolysis themselves or interaction with each other [18][19] .…”
