Problems solved by technology

The paper "Study on Sophora Sophorae Dyeing Cotton Fabric Technology and Its Anti-ultraviolet Properties" ("Dye and Dyeing" 2014 No. 1), expounded the anti-ultraviolet treatment technology of natural cotton fibers using natural ingredients, although it changed the existing chemical synthetic preparations. To achieve the anti-ultraviolet forming technology routine, but the finishing method also uses metal inorganic salts such as aluminum sulfate and ferrous sulfate as mordant to improve the dyeing degree of the fabric, and the anti-ultraviolet performance after 12 washings is also good. However, the solidification technology of the functional components of the metal salt inorganic salt mordant has also brought about environmental pollution problems that cannot be ignored.

Embodiment 1

[0011] At room temperature, immerse 2 g of cotton fabric in the anti-ultraviolet finishing agent for cotton fabric based on black rice anthocyanin, the bath ratio is 1:15, heat it up to 70°C and keep it warm for 60 min, then lower the temperature to room temperature, take out the cotton fabric, Dried at 70°C, then baked at 120°C for 5 min, and finally washed with water and dried again to obtain finished cotton fabrics. The black rice anthocyanin finishing agent for cotton fabric dyeing and ultraviolet radiation resistance described therein consists of: black rice anthocyanin extract 30 ml, citric acid 0 g / L, sodium citrate 3 g / L, sodium sulfate 1 g / L and Penetrant JFC 0.5 g / L.

Embodiment 2

[0013] Using the same finishing process as in Example 1, 2g of cotton fabric is immersed in the cotton fabric anti-ultraviolet finishing agent based on black rice anthocyanin, the bath ratio is 1: 15, wherein the cotton fabric dyeing and anti-ultraviolet radiation black The rice anthocyanin finishing agent consisted of: black rice anthocyanin extract 30 ml, citric acid 5 g / L, sodium citrate 3 g / L, sodium sulfate 1 g / L and penetrant JFC 0.5 g / L.

Embodiment 3

[0015] At room temperature, immerse 2g of cotton fabric in the anti-ultraviolet finishing agent for cotton fabric based on black rice anthocyanin, the bath ratio is 1:20, heat it up to 80°C and keep it warm for 90 min, take out the cotton fabric when the temperature drops to room temperature, and put it at 70°C Drying at 130°C for 3 min, and finally washing with water and drying to obtain finished cotton fabrics. The black rice anthocyanin finishing agent for cotton fabric dyeing and UV radiation resistance described therein consists of: 40 ml of black rice anthocyanin extract, 3 g / L of butane tetracarboxylic acid, 3 g / L of sodium citrate, and 1 g of sodium sulfate / L and penetrant JFC 0.5 g / L.

Abstract

The invention provide a black rice anthocyanin-based cotton fabric anti-ultraviolet finishing agent, which is prepared from the raw materials in total volume: black rice anthocyanin extracting solution, 0-5g / L of organic polybasic carboxylic acid, 0-5g / L of sodium citrate, 1g / L of sodium sulfate and 0.5g / L of penetrant JFC. According to the technical solution, cotton fiber and a fabric thereof are endowed with three finishing functions by a one-time finishing technology, and the fabric has the advantages of comfortable handfeel, environment friendliness, no pollution, low cost and capability of more fitting a human body.

Description

technical field [0001] The application of the present invention relates to a natural anti-ultraviolet finishing agent for cotton fabrics. Background technique [0002] The nutritional value and medicinal value of black rice are well known, and it also contains a large amount of natural pigments. The research results of natural color of fabrics, such as the article "Black Rice Pigment Stability and Dyeing of Wool Fabrics" in the second issue of "Wool Spinning Technology" in 2014, expounded the dyeing research of wool fabrics with black rice anthocyanins. Among them, gold ion inorganic salts including aluminum, iron, zinc, copper, tin, etc. are still used as mordants, such as ferrous sulfate, copper sulfate, aluminum sulfate, zinc sulfate and stannous chloride, etc., to improve the dyeing degree, but metal The existence of inorganic salt mordants is a technical factor that cannot be ignored in polluting the environment. [0003] The unique natural properties of cotton fiber ...
