Improvement of Crock Fastness in Dyed Fabrics

Improvement in Wash Fastness of Dyed Silk by Aftertreatment with Commercial Syntan/Metal Salts

Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...

First-Order Parametric Model of Reflectance Spectra for Dyed Fabrics

Wash Fastness of Textile Fibers Dyed with Natural Dye from Eucalyptus Wood Steaming Waste

Natural dyes are gaining interest due their expected low risk to human health and to the environment. In this study, the wash fastness of a natural coloring matter from the liquid waste produced in the steam treatment of eucalyptus wood in textile fabrics was investigated. Specifically, eucalyptus wood extract was used to dye cotton, nylon and wool in an exhaust dyeing process without the addit...

Synthesis of some monoazo disperse dyes derived from aminothienochromene.

A series of azo disperse dyes based on aminothienochromene were synthesized. The fastness properties of the dyed samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light fastness.

Microwave assisted dyeing of polyester fabrics with disperse dyes.

Dyeing of polyester fabrics with thienobenzochromene disperse dyes under conventional and microwave heating conditions was studied in order to determine whether microwave heating could be used to enhance the dyeability of polyester fabrics. Fastness properties of the dyed samples were measured. All samples dyed with or without microwave heating displayed excellent washing and perspiration fastn...
