preparation example Construction

[0030] c. Preparation of metal-plated textiles: Mix stabilizer, metal salt and reducing agent to obtain solution A; put the textiles dried in step b into solution A for microwave treatment, take them out, wash them with water, and dry them; The temperature of the microwave treatment is 30-80°C, and the treatment time is 5-10 minutes; the mass ratio of the stabilizer, metal salt and reducing agent is: 0.1-1:1:1-100;

[0031] Preferably, the microwave treatment in step c also includes turning over every 1 min.

[0032] In a specific embodiment, the cleaning in step a is: the textiles are ultrasonically cleaned in ethanol and acetone solutions for 10-30 minutes respectively.

[0033] The invention pre-treats the textile fabric with a coupling agent to enhance the binding force between the coating and the textile fabric.

[0034] In a specific embodiment, the textile is at least one of natural fiber fabrics or chemically synthesized textile fibers, or natural fiber yarns or chemi...

Embodiment 1

[0044] The bamboo pulp fiber fabric with a size of 5cm×5cm was ultrasonically cleaned with acetone and ethanol for 30 minutes respectively, and the fabric was taken out and dried naturally in a ventilated place; Dissolve 5ml of silane in 45ml of ethanol, add the solution to the dye kettle, put the cloth sample into the reaction kettle, take it out after supercritical static treatment at 10Mpa and 40℃ for 10min, and dry it in the air; add 0.08gAgNO 3 Dissolve in 40ml of deionized water respectively, add 6ml of 1% sodium citrate, and stir evenly; then put the silane-treated bamboo pulp fiber fabric into the above silver nitrate solution, heat it with microwave for 8min, turn over every 1min, wash with water, and Dry in an oven at 80°C.

[0045] The microstructure and macroscopic performance of gained nano-silver plating bamboo pulp fiber fabric are as follows:

Abstract

The invention relates to an impregnation or supercritical fluid assisted metal plating textile preparation method, and belongs to the technical field of textiles. The method provided by the invention comprises the following steps of a, textile pretreatment; b, impregnation or supercritical treatment with a coupling agent: dipping the textile in an acetone solution of the coupling agent, treating at 20-80 DEG C for 0.5-3 hours, and then drying, wherein the supercritical treatment comprises the following steps of soaking the textile in an ethanol solution of a coupling agent, carrying out supercritical static treatment for 10-60 minutes under the conditions of 5-20 Mpa and the temperature of 10-80 DEG C, and then taking out and drying; C, preparation of the metal plated textile: mixing a stabilizer, metal salt and a reducing agent to obtain a solution A; and putting the textile dried in the step b into the solution A for microwave treatment, taking out, washing with water, and drying. The product obtained by the method disclosed by the invention has the functions of static electricity resistance, ultraviolet resistance, electric conduction, electromagnetic shielding and the like, and is better in ultraviolet resistance. The method is environment-friendly, high in production efficiency and simple in process.

Description

technical field [0001] The invention relates to a method for preparing metal-plated textiles assisted by impregnation or supercritical fluid, and belongs to the technical field of textiles. Background technique [0002] Metal-plated textiles refer to the plating of metal particles on the surface of textiles by physical and chemical methods. Plating metal on the surface of textiles makes textiles have antistatic, conductive, electromagnetic shielding, anti-ultraviolet and other functions, thereby increasing the added value of textiles and increasing its application fields, such as clothing, home textiles, industrial textiles and other fields. [0003] At present, the methods for preparing metal-plated textiles mainly include physical deposition, chemical deposition, and supercritical fluid chemical deposition. Among them, the supercritical fluid chemical deposition method has application potential because of its excellent physical and chemical properties. Supercritical flui...
