Embodiment 1

[0044] 1. Preparation of Aloe Vera Extract:

[0045] Take fresh aloe leaves, cut 120g of aloe mesophyll, add 80mL of distilled water, boil for 15 minutes, filter with suction, and save the filtrate, which is the aloe extract; the obtained aloe extract can be sealed and stored at low temperature to keep it fresh.

[0046] 2. Processing technology:

[0047] Option 1: Take 1g of cotton fabric and soak it in silver nitrate solution for 1 hour in the dark, with a bath ratio of 1:50.

[0048] Option 2: Take 1g of cotton fabric, soak in aloe extract for 30 minutes, with a bath ratio of 1:20, and dry at low temperature; soak in silver nitrate solution for 1 hour, with a bath ratio of 1:50, and dry in vacuum.

[0049] Scheme 3: Take 1g of cotton fabric and soak it in silver nitrate solution for 1 hour, avoid light reaction, bath ratio is 1:50, take out the cotton cloth after the reaction, and vacuum dry it for 1.5 hours; take out the cotton cloth and soak it in the aloe extract for 30...

Embodiment 2

[0068] Test group: take a plurality of 1g cotton fabrics and soak them in silver nitrate solution with a mass concentration of 3% for 1 hour, and react in the dark with a bath ratio of 1:20. Take it out and soak it in the aloe extract at 40°C for 60min, the bath ratio is 1:15, take out the cotton cloth after the reaction is finished, and dry it at 60°C.

[0069] Control group: Untreated cotton fabric.

[0070] One, the cotton fabric that test group is processed and the untreated cotton fabric of control group are carried out electron microscope scanning, the result is as follows Figure 8 shown. Figure 8 The middle control group and the test group are the scanning electron micrographs of the blank cotton fabric and the same cotton fabric processed under the optimal process conditions respectively, Figure 8 The surface of the blank cotton fabric in the control group was smoother, while Figure 8 A large number of nanoparticles are attached to the treated cotton fabric, whi...

Abstract

The invention relates to the field of nano silver fabrics, and in particular, relates to a method for in-situ synthesis of nano silver fabrics with an aloe extracting liquid and the prepared fabrics. The method for in-situ synthesis of the nano silver fabrics with the aloe extracting liquid comprises the following steps: immersing cotton fabrics into a silver nitrate solution with the mass concentration of 1% or more, soaking for at least 20 min, and then carrying out vacuum drying; placing the dried cotton fabrics into the aloe extracting liquid, soaking with the soaking temperature of 30-55 DEG C and the soaking time of 30 min or more, and after the soaking is finished, drying the cotton fabrics at low temperature. According to the method for in-situ synthesis of the nano silver fabrics with the aloe extracting liquid, effective chemical components in aloe are subjected to a reaction with silver nitrate to obtain nanoparticles, and the organic chemical components in the aloe play a stable and green synthesis medium role, the obtained nanoparticles are combined in the cotton fabrics, anti-ultraviolet external properties and antibacterial properties of the cotton fabrics are significantly enhanced, and the fabrics have good washing durability.

Description

technical field [0001] The invention relates to the field of nano-silver fabrics, in particular to a method for in-situ synthesis of nano-silver fabrics from aloe extracts and the prepared fabrics. Background technique [0002] Due to its unique surface effect, volume effect, quantum size effect and macroscopic tunnel effect, nanomaterials present many exotic physical and chemical properties. It presents an extremely important application value. Applying nanomaterials to the field of textile functional finishing and developing multifunctional, high value-added fabrics will create huge economic and social benefits in the future textile industry. [0003] Existing studies have found that nano-silver is combined in textiles in a single form or in the form of a compound, which not only endows the fabric with long-lasting, high-efficiency, and spectral antibacterial functions, but also endows certain fabrics with antistatic, anti-electromagnetic radiation, electrical conductivit...
