The invention relates to a cellulosic fiber fabric reactive dye salt-free deep-color dyeing method, which comprises the following steps: (1) preparing a modifier aqueous solution, increasing the temperature to 60-80 DEG C, adding a test sample, stirring, adding sodium hydroxide, stirring, ...
In this study salt-free dyeing cotton fabric was achieved by grafting thiourea to cotton fibers, where the thiourea grafted cotton fabric (TUGCF) was prepared by epoxidizing cotton fibers with epichlorohydrin in water and subsequently grafting in aqueous solution of thiourea. Fourier transform ...
The TNA-reactive dyeing results and dye bath effluents were compared with those obtained by the conventional processes. The fastness properties of dyed cotton fabrics using different reactive dyes were also evaluated. Materials and methods Materials A bleached cotton fabric in plain weave (160 g/m2,...
Also the effects of chitosan concentration, type of mordents on dye uptake and antibacterial properties of samples were studied. All mordant fabrics have high adsorption compered to un-mordant ounces. The silk fabric treated with 0.6% chitosan had higher K/S values, washing and rubbing fastness....

Hydrogel fiber fabric Salt-resistant Large-scale production 1. Introduction The number of people suffering from a lack of reliable freshwater supply infrastructure may increase to 3.6 billion by 2025 [1], [2], [3]. The vision of a dual-carbon society is guiding the development of cost-effecti...
In both lithifying mats and microbialites, carbonate patches fused to form an intestine-like clotted thrombolite fabric (Supplementary Figs S2 and S3). The lower part of the microbialites showed a laminated structure (strom- atolitic; Fig. S2F). The X-ray diffraction patterns (Fig. 2A) ...
Alkali-assisted oxidation and sulfidation were utilized to achieve in situ growth of copper sulphide on the fibers. Firstly, the needle-punched polyester nonwoven fabric was immersed in a 0.2 mol per L CuCl2 solution. It was then immersed in a 0.5 mol per L NaOH solution for 5 seconds and...
While the above prior art methods have provided ways to dye or color synthetic fibers, such as polyester or polyolefin, problems have nevertheless been encountered. Such problems have been, in the case of polyester, severe crocking and migration of the dyestuff from the dyed fabric, especially wh...
to a caustic solution under tension. The yarn then is dyed under tension by exposure to a dye liquor. The treated yarn is used to produce a woven fabric, which after being abraded, has a lighter portion dispersed throughout a darker portion. In the preferred embodiment the twist multiple ...
