Embodiment 1

[0046] (1) Prepare 0.8mol / L zinc acetate aqueous solution A and 0.4mol / L terephthalic acid aqueous solution B respectively. Cotton fabrics were soaked in solution A at 70-75°C for 5 minutes with a liquor ratio of 1:50, washed with water at room temperature, and dried at 80°C for 30 minutes; then soaked in solution B under the same process conditions as solution A, washed with water, drying. After repeating the above steps 8 times, the Zn-MOF pretreated cotton fabric was obtained.

[0047] (2) Prepare chloroform solution C with rhodamine 6G dosage of 4.0% owf, bath ratio is 1:50, dip Zn-MOF pre-treated cotton fabric in solution C for 48 hours at 20°C, take it out, and place it in trichloromethane Rinse in methane and dry to obtain Zn-MOF dyed cotton fabric. Prepare a 0.1 mol / L europium acetate aqueous solution D, soak the Zn-MOF dyed cotton fabric in the solution D for 12 hours at 20°C, take it out, wash it with water at a bath ratio of 1:50, and dry it at 80°C for 45 minutes...

Embodiment 2

[0052] (1) Prepare 0.6mol / L zinc chloride aqueous solution A and 0.4mol / L trimesic acid aqueous solution B respectively. Cotton fabrics were soaked in solution A at 70-75°C for 5 minutes with a liquor ratio of 1:50, washed with water at room temperature, and dried at 90°C for 25 minutes; then soaked in solution B under the same process conditions as solution A, washed with water, drying. After repeating the above steps 8 times, the Zn-MOF pretreated cotton fabric was obtained.

[0053] (2) Prepare chloroform solution C with 2.0% owf of crystal violet, the bath ratio is 1:50, dip and dye the Zn-MOF pre-finished cotton fabric in solution C for 36 hours at 25°C, take it out in chloroform Rinse in medium and dry to get Zn-MOF dyed cotton fabric. Prepare a 0.05 mol / L europium chloride aqueous solution D, soak the Zn-MOF dyed cotton fabric in the solution D for 12 hours at 25°C, take it out, wash it with water at a bath ratio of 1:50, and dry it at 90°C for 30 minutes to obtain M...

Embodiment 3

[0055] (1) Prepare 0.4 mol / L zinc nitrate aqueous solution A and 0.1 mol / L pyromellitic acid aqueous solution B respectively. Cotton fabrics were soaked in solution A at 70-75°C for 8 minutes, with a bath ratio of 1:20, washed with water at room temperature, and dried at 100°C for 20 minutes; then soaked in solution B under the same process conditions as solution A, washed with water, drying. After repeating the above steps 12 times, the Zn-MOF pre-treated cotton fabric was obtained.

[0056] (2) Prepare a 0.01mol / L samarium chloride aqueous solution C, soak the Zn-MOF pretreated cotton fabric in the solution C for 18 hours at 30°C, take it out, wash it with water at a bath ratio of 1:20, and dry it at 100°C 20min, the fluorescent cotton fabric based on Zn-MOF was obtained. Prepare chloroform solution D with rhodamine B content of 1.0% owf, bath ratio is 1:20, dip and dye Zn-MOF-based fluorescent cotton fabric in solution D for 24 hours at 30°C, take it out in chloroform Af...

Abstract

The invention relates to a preparation method of a multifunctional dyed fluorescent cotton fabric based on MOF. The method includes the steps of preparing a pretreated Zn-MOF cotton fabric and preparing the multifunctional dyed fluorescent cotton fabric based on the Zn-MOF. The method is simple in process operation and high in efficiency and requires no special equipment, raw materials are low incost and easy to obtain, and the method is suitable for industrial production. The prepared multifunctional dyed fluorescent cotton fabric based on the Zn-MOF is excellent in fluorescent performance and meanwhile has the properties of resisting bacteria, preventing generation of stink, mold and moths, resisting ultraviolet rays, retarding inflaming and the like.

Description

technical field [0001] The invention belongs to the field of preparation of fluorescent cotton fabrics, in particular to a method for preparing MOF-based multifunctional dyed fluorescent cotton fabrics. Background technique [0002] As an important category of cotton fabric products, fluorescent cotton fabric is of great significance for enriching the types of cotton fabrics. At present, the commonly used fluorescent fabric products are basically chemical fiber products, such as polyester, acrylic, nylon, etc., but there are few reports on cotton fabrics with excellent fluorescent effects. At the same time, the fluorescent pigments used for dyeing cotton fabrics on the market are mainly fluorescent paints. Pigment-dyed cotton fabrics often have problems of poor color fastness to rubbing and poor hand feeling. Dyeing cotton fabrics with fluorescent dyes can solve this problem very well. The hand feel is better than that of fluorescent paint-dyed cotton fabrics, and the fastn...
