Embodiment 1

[0014] (1) Cotton fiber yarns are used as warp yarns, cotton fiber yarns are used as weft yarns, warp yarns and weft yarns are interwoven into cotton fabrics, the number of warp yarns is 50, and the number of weft yarns is 50;

[0015] (2) Add cotton fabric, potassium hydroxide and 3-chloro-2-hydroxypropyltrimethylammonium sulfate into a water bath filled with water in turn, heat for 40 minutes, then add acetic acid dropwise to the water bath to bring the solution to medium Add turmeric dye to the water bath for dyeing. At this time, the set temperature of the water bath is 80°C to obtain a yellow cotton fabric.

Embodiment 2

[0017] (1) Cotton fiber yarns are used as warp yarns, cotton fiber yarns are used as weft yarns, warp yarns and weft yarns are interwoven into cotton fabrics, the warp yarn count is 60, and the weft yarn count is 55;

[0018] (2) Add cotton fabric, potassium hydroxide and 3-chloro-2-hydroxypropyltrimethylammonium sulfate into a water bath filled with water in sequence, and after heating for 49 minutes, add acetic acid dropwise to the water bath to bring the solution to medium properties, then add turmeric dye to the water bath for dyeing. At this time, the set temperature of the water bath is 70°C to obtain a yellow cotton fabric.

Embodiment 3

[0020] (1) Cotton fiber yarns are used as warp yarns, cotton fiber yarns are used as weft yarns, warp yarns and weft yarns are interwoven into cotton fabrics, the number of warp yarns is 55, and the number of weft yarns is 45;

Abstract

The invention discloses a dyeing method for yellow cotton fabric. The dyeing method comprises the following steps of: with cotton fiber yarns as warps and cotton fiber yarns as weft yarns, interweaving 50-60 warps and the 45-55 weft yarns into the cotton fabric; adding the cotton fabric, potassium hydroxide and 3-chlorine-2-hydroxypropyl trimethyl ammonium sulfate to a water bath kettle with water in sequence; heating for a period of certain time and dropwise adding acetic acid to the water bath kettle till the solution becomes neutral; adding curcuma dye to the water bath kettle for dyeing to obtain the yellow cotton fabric. According to the dyeing method for the yellow cotton fabric, provided by the invention, a modifying agent is used to modify the cotton fabric so that the dyeing performance of the cotton fabric is improved and the natural curcuma dye is firmly adhered to the cotton fabric, and the cotton fabric still can keep bright after being washed by a plurality of times and does not dye other objects in contact with the cotton fabric. Besides, the cotton fabric is dyed uniformly without color difference, does not change colors by light irradiation.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for dyeing yellow cotton fabrics. Background technique [0002] With the development of the chemical industry in recent decades, more and more synthetic dyes have been developed and applied. Synthetic dyes have also been widely used for their excellent color fastness and colorful colors. However, in recent years, fashion and textiles have begun to return to naturalization. Natural dyes are favored by more and more consumers because of their biodegradability and integration with the environment. [0003] Turmeric is a perennial herb belonging to the genus Curcuma longa of the Zingiberaceae family. It contains a variety of chemical components and has good medicinal value. It is also one of the most famous and brightest natural yellow dyes. However, the adhesion of traditional turmeric dyes to fabrics is not reliable, and it is easy to fade and stain when used for a long tim...
