Polyethylene terephthalate is one of the important synthetic ester polymeric material used in widespread areas.  In textile industry, this fibrous material finds use in most of the garment and apparel applications due to its ease of handling, maintenance, and drying and competes with cotton materials.  However, due to the maximum hydrophobic behavior, this textile material gives number of issues like accumulation of statics, negligible moisture content, poor comfort and aesthetic characters.  Hence, in order to use this polyester material in the general textile industries particularly for garment and apparel productions, it is necessary to increase to some extent of its hydrophilic character by the application of some suitable chemicals like polyvinyl alcohol.  In these context, in this work an attempt is made to treat the polyethylene terephthalate fabric with sodium hydroxide followed by polyvinyl alcohol so as to increase the aesthetic properties.  The output received after the polyvinyl alcohol treatment on this fabric gives the good results expected for the garment applications.

A novel functional disperse dye doped with graphene oxide for antistatic properties of polyester fabric was achieved, which means that the dyeing and antistatic finishing can be simultaneously obtained by a one-bath method. Functional dyes were used to dye polyester fabric by a high-temperature, high-pressure dyeing method. The surface microscopic morphology of the dyed polyester fabric, and the dispersion properties of the disperse dye, graphene oxide, and the functional disperse dye, were characterized by scanning electron microscopy. The effects of the dyeing temperature on the particle sizes of three dyeing liquors were explored; this revealed that the temperature of the dyeing process had no effect on particle size. The dosage and reduction time of graphene oxide were investigated. The surface electrical resistance of the dyed fabric, 9.8 × 106 Ω, obtained at a condition of 2% (o.m.f) graphene oxide with a reduction time of 30 min, achieved A-grade antistatic standard. Furthermore, the rubbing and washing fastness of the treated fabric were 4- and 4 ∼ 5 grades, respectively. This preparation of the functional disperse dye provides a possibility in one-bath dyeing and antistatic finishing of polyester fabric.

This paper discusses the synthesis and preparation of polyvinyl alcohol based nanocomposites through the use of miniature thermoplastics processing technology. It studies the influence of different process conditions, the amount of raw materials and water on the processing performance, tensile strength and elongation at break of polyvinyl alcohol based nanocomposites. Studies have shown that using two miniature thermoplastic processes does not have much influence on the mechanical properties of polyvinyl alcohol based nanocomposites, different amount of polyvinyl alcohol will lead to enhancement of the tensile strength of the polyvinyl alcohol based nanocomposites system by the increasing amount of glycerin, and the water content has a great influence on the performance of polyvinyl alcohol based nanocomposites. To this end, according to the analysis of experimental results, it can obtain preparation conditions and influencing factors of polyvinyl alcohol based nanocomposites with the miniature thermoplastic processing conditions, and provide a new theoretical method and means for nanocomposites.

The effect of dye dispersion preparation prior to dyeing on the dyeing ability of the disperse dye on polyester fabric was studied. The influence of sodium laurylsulphate (SLS) concentrations and the homogenization process was determined. The optimum SLS concentration for dyeing observed in this study was 0.01 M. The color yield of the dye passing through the homogenization process on polyester fabric was higher than that from the conventional dye preparation. Homogenization was also found to enhance disperse dyeability at a lower dyeing temperature. It infers that the dyeing process could be done at a lower temperature. The dyeing temperature could be as low as 110oC in the presence of homogenization. The effect of homogenization on the dyeability at different dyeing times was also examined.

The present study aims to evaluate the application of coumarin as a green carrier alternative for dyeing of polyester fabrics, as well as to optimize key dyeing parameters in order to obtain greater color strength (K/S) at lower temperatures than 130°C using single azo class dispersed dye. For this purpose, a full-factorial design was used to study the influence of the single and interactive effects of four factors involved in the dyeing process, namely, pH, temperature, and coumarin and dye concentrations. The chosen technique was a 24-factorial, one-center point, and three replicates at the center point resulting on a response surface, which has shown an increase of the color strength of five times at 90°C, and of three times at 100°C when compared to dyeing at the same temperatures without the use of a carrier. In addition, excellent fastness to washing and to rubbing were obtained.

Important Index

Cotton is one of the world’s most common natural clothing materials. It is dyed mainly using the exhaustion, cold pad-batch, and pad-dry-pad-steam dyeing methods. The K/S value, an important index for measuring the depth of color, of cotton fabric dyed with reactive dyes is greatly influenced by various factors of the dyeing process. In this study, three models were developed incorporating least squares support vector machine (LSSVM) to predict the K/S values of dyed cotton fabrics, while particle swarm optimization (PSO) was applied to optimize and tune the parameters of the LSSVM model (PSO-LSSVM). Model inputs include dye concentration and process conditions, which are both easily obtainable variables. The K/S values from the PSO-LSSVM model are consistent with actual measured K/S values of dyed cotton fabrics. Moreover, a comparison among PSO-LSSVM, LSSVM and back propagation neural network results shows the superiority of the PSO-LSSVM approach. Results of this work indicate that a PSO-LSSVM model is a powerful tool for predicting the K/S value in cotton fabric dyed with reactive dye and thus a means to improve production processes and reduce costs.

The aim of the study was to dye polyester fabric with a low molecular weight anthraquinone type disperse dye (C.I. Disperse Blue 56), with n-butylacetate as co-solvent in the microemulsion system and the presence of two bio-based auxiliaries (ortho-vanillin and coumarin), at temperatures lower than 100℃. In order to investigate the influence of temperature and auxiliaries on the kinetic dyeing process, the energy of the activation was determined by the kinetic rates constants. The activated entropy values were obtained by the theory of absolute rates of dyeing and diffusion of the activated state of the dye for the disorder state of the dyeing system. Higher activated energies were found, as well as higher activated entropy, meaning higher dye absorption, for polyester samples dyed with ortho-vanillin/n-butylacetate compared with polyester samples dyed with coumarin/n-butylacetate. Color strength values of the polyester fabric dyed using the proposed microemulsion dyeing system at low temperature (95℃) were similar to polyester fabric dyed with a conventional dyeing system at high temperature (135℃). Regarding color fastness to washing and ironing, it was found that the use of the auxiliaries did not significantly modify the fastness values of the dyed samples.
