Accessibility of acrylic fiber to basic dye

Abstract

The accessibility of the fiber to dye is considered to be related to the fraction of the polymer segment which is mobile. This is studied by dyeing the acrylic fiber at temperatures within a 40°C range while treating the samples with different carriers. The relation of the equilibrium dye uptake (dyeability) of the acrylic fiber to the structural parameter, ∫ italicT20 (tanδ)cdT, with the presence or absence of carrier in solution is linear, confirming the validity of the hypotheses, where (tan δ)c is the loss tangent correlated at a temperature of 20°C. Moreover, The effect of carrier to swell the amorphous region of the acrylic fiber was less effective as temperature beyond Tg (mechanical). © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009

Preparation of novel hyperbranched flame‐retardant polymer and its application into natural rubber systems

“…These groups came from the hyperbranched repeat units and the phosphate acid ester grafted over the surface of PER. 15 The 1 H-NMR spectra of PER and FR-HPER were illustrated in Figure 2. Two bands of PER were observed between 1.5 and 1.6 This was attributed to the ACH 2 groups in the different environment resulted from the repeat units of the branched polymers.…”

Effect of Dyeing Temperature on the Shrinkage and Fastness Properties of Polyester/Acrylic Fabric

“…The colour strength of the dyeing generally increased with increasing application temperatures (Sona et al, 2004). Thermodynamic factor and the structural factor of dyeing of acrylic fibre with basic dyes were reported by Wang (2009). The aim of this study is to characterise the factors that influence the fabric shrinkage with temperature gradient.…”
