Butanetetracarboxylic Acid

Cotton fabrics were treated with 1,2,3,4-butanetetracarboxylic acid (BTCA) and then dyed with a natural dye extracted from henna (Lawsonia inermisLinn.) leaves. The effect of BTCA concentration on the dyeing properties of cotton fabrics was studied by measuring the K/S values of the treated dyed cotton fabrics. The wrinkle recovery angles of the treated dyed cotton fabrics were assessed. The results proved that the BTCA treated cotton fabrics showed increase dye uptake of cotton fabrics. Concentration of BTCA enhances the durable press and tensile strength of the dyed cotton fabrics. Fastness properties of these to wash, rub and light have also been discussed.

Finishing Agent

Chitosan, a naturally available biopolymer, was used as finishing agent to increase dye uptake and color fastness of cotton fabrics. Thian King leaves extract a natural dye was applied on cotton fabrics after chitosan treatment. The whiteness index and tensile strength of samples were measured to study the effect of chitosan application. The color of dyed samples was investigated in term of the colorimetric parameters (L*, a*, b*, ∆E) and K/S values. The color fastness to washing, rubbing and light of dyed samples was determined according to AATCC test method. The results showed that the chitosan concentration enhances the whiteness index and tensile strength of the treated cotton fabrics. Chitosan treatment showed increase dye uptake of cotton fabrics. Fastness properties of these to washing, rubbing and light have also been discussed.

Color Yield

The main goal of this work was to study the possibility of improving the natural dye uptake and their fastness properties on cotton fabrics by the application of monochlorotriazine-β- cyclodextrin (MCT-β-CD). Hence, MCT-β-CD was synthesized, characterized, and grafted on cotton fabrics via pad and cure method. The existence of MCT-β-CD on cotton fabrics was confirmed by nitrogen content (%N). Natural dyes used were colorants extracted from turmeric and cassumunar powders, and a commercial natural dye i.e. Natural Red Brown. The commercial one was water soluble whereas the extracted dyes were sparingly soluble in water. These natural dyes were applied on cotton by pad-dry method. The extracted dyes on MCT-β-CD treated cotton fabrics gave higher visual color yield (K/S) than the untreated ones. In contrast, a commercial natural dye exhibited lower color yield on the treated fabrics because of its water soluble nature. The color fastnesses of the natural dyes on the treated cotton fabrics were improved from the untreated cotton samples.

Ph Values

Natural dye was extracted from the mangosteen pericarps using UE method. The work dealed with the investigation of cotton fabric samples dyed with natural dye. The effects of different dye concentrations and pH values were estimated by the dye-uptake(K)and the color difference(△E). And the effects of different dyeing methods of direct dyeing, pre-mordant and after-mordant were tested when alum was used as a mordant. The highest K and △E were obtained on using pre-mordant method when dye concentration was used as 30g/L and pH value as 3. And the color fastness properties of rubbing, washing and perspiration were tested. Compared with the pre-mordant method, it was quite satisfactory for after-mordant method where its ranged between 2-3 to 4-5.

Butanetetracarboxylic Acid

The silica sol was applied onto 1, 2, 3, 4-butanetetracarboxylic acid (BTCA) finished cotton fabrics with the attempt to improve the physical properties especially the tensile strength which had a big loss in the previous anti-crease finishing processing. The parameters including the dosage of the coupling agent, the concentration and pH of the sol and the processing methods were studied in detail. Compared to the sample finished with BTCA, 11.8% of the increase in the crease recovery angle and 18.6% of the enhancement in the tensile strength of the cotton fabric also treated with silica sol in the better selected conditions were obtained. The abrasion resistance was also improved.

The current study deals with the extraction of natural dye from Bombax malabarica flowers, readily available by-product. Dye was extracted under different operating conditions such as time (60–90 min), temperature (90–95 °C), and pH 9. The dyed samples were subjected to CIELAB system using Gretag Macbeth Color Eye 7000A Spectrophotometer for the evaluation of color strength and L*a*b* C and H values. To improve the dye uptake and color fastness, pre and postmordanting was carried out using alum, tannic, and tartaric acid mordants. Dyed silk fabrics were tested for its color fastness when subjected to light, washing, and rubbing. Fastness properties of dyed silk fabric samples were found considerably good. Mordanted silk fabric samples showed increase in dye uptake resulting in high color strength and better fastness properties. The dyed silk samples displayed good antimicrobial activity (reduction rate: 48%) against the bacteria Escherichia coli and (reduction rate: 55%) against Staphylococcus aureus.
