This study presents findings on the effect of several domestic laundry detergents on the fastness to light of selected fiber reactive dyes applied to cotton. Cotton fabric dyed with commonly used reactive dyes were laundered with water only, several domestic detergents, and a laboratory-formulated neutral detergent, and then exposed to light for 2 h in the wet state. Exposures were repeated 15 times, equivalent to 30 h of exposure. Color loss and color difference were measured after 5, 10, and 15 wash cycles, and 10 h, 20 h, and 30 h of exposure. When the fabric was exposed to light wet, the color faded more rapidly than when it was exposed dry. The presence of an oxidizing bleach (sodium perborate or sodium percarbonate) in the detergent increased color loss during washing and wet exposure to light. Ultraviolet radiation from the light source, heat, moisture, alkali, and oxidizing bleach during exposure resulted in hydrolysis of the dye–fiber bond, causing dye desorption during washing and rinsing. The combination of ultraviolet radiation and oxidizing bleaches altered the chemistry of the dye and hence its shade. This was particularly evident on the black dye and one of the navy blue dyes.

Biopolymers are suitable replacement materials for different chemical processes. In this work, silk yarns were treated with different chitosan concentration and then dyed with mono and bi-functional reactive dyes. The color yield, color difference and color fastness to light and washing of the dyed silk yarns were evaluated. Also, the effects of chitosan concentration, type of the reactive dyes on dye uptake of samples were studied. The bi-functional reactive dye has a high adsorption compared to mono-functional ones. The silk yarn treated with 3% chitosan had higher K/S values, washing and light fastness. The effects of chitosan on the antibacterial properties of silk yarns against two kinds of bacteria: Staphylococcus aureus and Escherichia coli were investigated. The treated silk samples were found to have antibacterial potential due to the antibacterial property of chitosan. Scanning electron microscopy (SEM) photographs reveal the deposition of chitosan on the treated yarns. Washing durability, handle properties, and yellowness of treated and dyed samples were also investigated.

Purpose The present study aims to focus on the feasibility of using an aqueous extract from the fruit shell of Camellia oleifera Abel as a source of natural colourant in printing-paste preparation for pigment printing of cotton fabric. The effects of pre- and post-mordanting with three common metallic mordants, that is AlK(SO4)2, CuSO4 and FeSO4 on colour yield and colour fastness properties are also investigated. Design/methodology/approach The printing paste was prepared by mixing the concentrated Camellia oleifera Abel fruit shell extract solution with commercially available synthetic thickener and binder. The fabric sample was printed with the prepared printing paste using a flat-screen printing technique. To determine the effects of pre- and post-mordanting, AlK(SO4)2, CuSO4 and FeSO4 mordant aqueous solutions with various concentrations were applied using the pad-dry technique. Comparisons between printing with and without mordants were evaluated in terms of colour strength (K/S values) and colour fastness to washing, light, crocking and perspiration. Findings Without the mordants, the printed fabric had a yellowish brown shade with acceptable colour fastness properties, that is fair to good wash fastness, moderate light fastness, good to very good crocking fastness and fair to good perspiration fastness. The use of mordants, especially CuSO4 and FeSO4, not only enhanced colour strength but also imparted different colours to the fabric. Compared to the unmordanted fabrics, colour fastness properties were mostly comparable or improved in the mordanted fabrics depending on the type and concentration of mordants. Research limitations/implications Although in the case of CuSO4 the light fastness was increased to a good to very good level, it is recommended that the final print be produced with a concentration of less than 0.125 gL−1 to yield the print with the residual amount of Cu metal under the limit, that is less than 50 ppm as regulated by the Oeko-Tex® standard. Practical implications The obtained prints from Camellia oleifera Abel fruit shell extract provided shades with satisfactory colour fastness to washing, light, crocking and perspiration. The extract from Camellia oleifera Abel fruit shell has the potential to be used as an alternative to synthetic dye in the textile industry. Originality/value The use of Camellia oleifera Abel fruit shells, which are considered as abundant byproducts of tea seed oil production, as natural colouring agents for pigment printing of cotton fabric has been reported for the first time. It will minimise the environmental impact of this waste and create more valuable textile products.

Cotton fabric was dyed with Liyuan Blue FL-RN reactive dye. The dye exhaustion and fixation percentages were calculated for all light, medium and dark shades. The dye shows very good exhaustion and fixation properties. Dyed samples were tested for light fastness property as per international standards. The results indicates the dye has a good light fastness property. The effect of UV absorber was studied in order to improve light fastness property. Cationic UV absorber CANFIX SUN was applied on the dyed cotton fabric by exhaust method. The results show that the color depth was similar after UV absorber treatment. In all the cases the use of UV absorber improved the light fastness of dyed fabrics as compared to untreated dyed samples.

The main objective of this work is to investigate the effect of nano-chitosan on the dyeing of polyester fabric with reactive dyes. Polyester fabric was treated with alkali and coated with nano-chitosan. Afterwards all samples were dyed with reactive dyes. The water absorption and bending resistance of pristine polyester, alkaline and chitosan-treated polyester were measured. In order to investigate surface chemical bonding, FTIR/ATR was employed. Surface morphology of fabrics was observed using scanning electron microscopy (SEM). Wettability and bending behavior of the treated polyester increased compared to the untreated one. The color difference between the dyed blank and chitosan-treated samples was estimated using a spectrophotometer. The data obtained shows it is possible to use reactive dyes to dye polyester fabrics finished with nano-chitosan and the resulting fabrics will exhibit acceptable washing and rubbing fastness.

Weave Pattern

This paper investigated the color difference, whiteness, and luster of multifilament polyester woven fabrics based on weave pattern, weft density, dye concentration, and interaction between super bright warp yarns and semi dull weft yarns. Plain, weft rib (2/2), sateen (1/4)(3) and steep twill(2/3) was selected as weave pattern. Warp yarn type and its count, and warp density were kept constant. Measurement of whiteness was conducted on pre-treated un-dyed fabric samples. Color difference and luster of samples was evaluated after dying in warp and weft direction separately. Plain and weft rib (2/2) weaves showed the lowest and highest value of whiteness and luster respectively. Interaction between weave pattern and application of super bright yarn as warp was obtained in these parameters. The luster and whiteness of samples was decreased by increase in weft density. The trend of luster and color difference in weft and warp direction by increasing the weft density was not similar and was dependent on dye concentration and effectiveness of super bright warp yarns according to fabric pattern. Woven fabrics with steep twill (2/3) and weft rib (2/2) revealed the highest values of color difference compared with plain and sateen (1/4)(3) in warp direction. In weft direction, plain weave showed the lowest value of color difference and all three others had almost the same level of color difference. Moreover, the visual assessment was organized based on twenty-two observers in standard condition and D65 light source.
