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.

This work aims to conduct an eco-friendly textile finishing process by applying agricultural by-products as a dye for the of polyamide fabrics. A natural was obtained from pomegranate peel extract. Polyamide fabrics were dyed at different conditions, and four mordanting agents tested. The finished analyzed in terms CIE L, a, b color yield (K/S) values, well washing fastness, rubbing light fastn...

Indonesia is among the largest countries in global rice production. Annual generation of straw about 20 million tons were reported. It therefore, utilization as natural dye considered to minimize pollutant problem. Rice composed 48.7% carbon that generate black color. In this research, dyes ash applied cotton and rayon fabrics, followed by mordanting using lime, alum, ferrous sulphate. The colo...

A series of monoazo disperse dyes derived from arylazothienopyridazines were synthesized. Fastness properties of dyed polyester samples were measured. Most of the dyed fabrics tested displayed excellent washing and perspiration fastness and moderate light fastness. Finally, the biological activity of the synthesized dyes against Gram positive bacteria, Gram negative bacteria and yeast were eval...

Abstract The color fastness to light of textile in the product standard is always tested by method 3 GB/T 8427, which determines endpoint exposure according discoloration blue wool sample. aging xenon lamp for resulted different sun times references required same level. As a result, difficulty testing increased, and test accuracy was also affected. In this paper, relationship between time servi...

In this study, 100% soybean and cotton suprem pique knitted fabrics were produced. Quality performance parameters, color fastness spectrophotometric results of the compared. The aim study is to reveal advantages weaknesses compared fabrics. When production test are examined, softer than Knitted protein fiber dimensional change worse cotton. Air permeability made from better therefore it can be ...

Cellulosic materials like cotton and linen are excellent textile substrates for dyeing with reactive direct dyes. Due to their cellulosic nature, exhibit good affinity towards This is the reason washing rubbing fastness. Chitosan a bio-based polymer gained by deacetylation of chitin. In contrast cellulose, chitosan exhibits also amino functional groups. The purpose this paper evaluate if based ...
