Development of chitosan as a thickener for direct printing of natural dye on cotton fabric was investigated. Chitosan was applied as a thickener at various concentrations and its effect on the print properties was determined in comparison with the typical printing thickener, sodium alginate. The results exhibited that chitosan affected the fabric properties by increasing fabric yellowness and stiffness. However, with increasing chitosan concentrations, the yellowness reduced only marginally. Direct printing on cotton fabric with 3% Natural Chestnut at varying chitosan concentrations showed that the optimum chitosan concentration for the printing was at 3%w/v, being equivalent to the viscosity of 17,800 mPa. The 3%w/v chitosan imparted the ultimate color yield, print outline sharpness and a minimal dye bleeding on the unprinted area of the fabric. Use of chitosan concentration higher than 3%w/v led to poor print properties on the fabric. The efficiency as a thickener of chitosan was found to be superior to sodium alginate. A high color yield and good color fastness properties on cotton fabric were rendered in the case of chitosan thickener at the same applied concentration with sodium alginate.

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.

Indigo, one of the oldest dyes, has a very important role for the textile sector. It is primarily used to dye cotton clothes, and blue jeans and over one billion pairs of jeans around the world are dyed blue with indigo. Although Sodium Hydrosulfite (Na2S2O4) is used as a reducing agent in most indigo dyeing processes, it is environmentally unfavorable because of the resultant contaminated toxic wastewater. In addition, the color fastnesses of dyed samples using Na2S2O4 as reducing agent are not good enough.In the present paper sodium borohydride (NaBH4) were used as ecologically safe reduction systems for the indigo dyeing of cotton fabric. After dyeing processes, the color yield and fastnesses according to washing and rubbing were measured, and results were compared.It was found when NaBH4 was used as reducing agent instead of Na2S2O4, the color yield and the fastness properties of the dyed samples improved.

Purpose The purpose of this paper is to explore a new eco-friendly green textile dyeing. Natural plant Buddleja officinalis is traditionally used as yellow pigment addition in rice. It is worth developing its application and dyeing performance in cotton fabric. Design/methodology/approach Buddleja officinalis dried flower was extracted with ethanol aqueous. The extraction conditions including ethanol concentration, material to liquor ratio, extract time and temperature were optimized. Then cotton fabrics were dyed with Buddleja officinalis extraction under conventional and ultrasonic conditions. The effects of dyeing time, bath ratio, pH value of dyeing bath, dyeing temperature and mordants on K/S values were studied and the resulting color strength obtained by conventional and ultrasonic dyeing were compared. The ultraviolet (UV) transmittance of Buddleja officinalis dyed cotton fabric was also evaluated. Findings The color strength of the fabric dyed with Buddleja officinalis under ultrasonic conditions was higher than that under conventional conditions. Alum, Fe and Cu as simultaneous mordants improved the K/S value of the dyed cotton fabrics. Both washing fastness and rubbing fastness were fairly good in all Buddleja officinalis dyed cotton fabrics, washing fastness = 3–4 and rubbing fastness = 4. What’s more, the dyed cotton fabrics showed lower transmittance values as compared to undyed cotton fabrics and indicated potential UV protection capability. Practical implications Buddleja officinalis can be a new natural dye source for the ultrasonic dyeing of cotton fabric. Originality/value It is for the first time that Buddleja officinalis is used as a natural dye in cotton fabric dyeing with less water and the dyeing using ultrasound has been found to have an obvious improvement in the color strength and color-fastness.

This study investigated the use of a thickening agent derived from modified starch of wild taro corms in the screen printing of cotton fabric using reactive dye. The best conditions for developing the print paste and steaming time in order to obtain maximum color yield were established. The results revealed impressive color fastness properties in the printed samples; although, the printed fabric possessed slightly lesser tensile and tear strength, in comparison with the unprinted fabric. The printed fabric also exhibited increased bending stiffness properties. Largely, this study reveals that the printing paste containing the thickening agent derived from carboxymethyl starch within wild taro corms can be utilized in the printing of cotton fabric using reactive dye.
