Embodiment 1
[0011] The detailed steps of curcumin to the dyeing method of cotton fabric are as follows:
[0013] (2) Dissolve 1g of curcumin in the above dimethyl sulfoxide / phenol mixed solution, then add 0.04g of surfactant sodium dodecylbenzenesulfonate, and obtain a transparent solution under ultrasound;
[0014] (3) Put 10g of cotton fabric into the above dyeing solution, vibrate and heat to 60ºC, keep warm and dye for 30min;
[0015] (4) Wash the dyed fabric in dimethyl sulfoxide and dry it at 80ºC.
Embodiment 2
[0017] The detailed steps of curcumin to the dyeing method of cotton fabric are as follows:
[0018] (1) Dissolve 300g phenol in 100g dimethyl sulfoxide;
[0019] (2) Dissolve 0.1g of curcumin in the above DMSO / phenol mixed solution, then add 0.08g of surfactant sodium dodecylbenzenesulfonate, and obtain a transparent solution under ultrasound;
[0020] (3) Put 10g of cotton fabric into the above dyeing solution, vibrate and heat to 30ºC, keep warm and dye for 30min;
[0021] (4) Wash the dyed fabric in dimethyl sulfoxide and dry it at 80ºC.

Abstract
The invention provides a method for dyeing a cotton fabric with curcumin. The method comprises the following steps: dissolving curcumin into a dimethyl sulfoxide / phenolmixed solution, further adding a surfactant sodium dodecyl benzenesulfonate, and performing ultrasonic treatment so as to obtain a transparent solution; putting the cotton fabric into the solution, oscillating and heating to 30-60 DEG C, and dyeing the cotton fabric. By adopting the dyeing technique, the curcumin does not need to be modified, high-temperature dyeing is avoided, and a dyed fabric is high in color fastness.
Description
technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a method for dyeing cotton fabrics with curcumin. Background technique [0002] Curcumin is a chemical component extracted from the rhizomes of some plants in Zingiberaceae and Araceae, and it is a diketone compound. Curcumin is orange-yellow crystalline powder, insoluble in water. Curcumin is a traditional natural dye with bright yellow color, which has good compatibility with the environment and is harmless to human health. However, curcumin is poor in directly dyeing cellulose fibers such as cotton, and its color fastness is poor. Contents of the invention [0003] In order to make curcumin effectively dye cotton fabrics, the present invention takes the following technical solutions. [0004] A method for dyeing cotton fabric with curcumin, comprising the steps of: (1) dissolving phenol in dimethyl sulfoxide; (2) dissolving curcumin in a mixed solution of dimethyl ...
