Problems solved by technology

[0004] At present, the preparation of smart fibers is mainly obtained through the following methods, directly using polymers with intelligent change ability to spin or blending and spinning polymers with change ability and other polymers to obtain smart fibers. This method is only applicable to limited Several polymer materials, which limit the strength of the fiber and the application environment
Another method is to graft polymers with changing capabilities on the surface of existing fibers or use binders to directly combine changing polymers with fibers; there are also research reports on the combination of responsive particles and fiber materials, But most use binders to bind the particles to the fibers, but this limits the ability to change
The above methods basically require complex processes, which severely limit the universality of their preparation methods and the applicability of smart fibers.

Embodiment 1

[0048] Disperse 10 mg of polyacrylamide particles containing carboxyl groups in 50 ml of water, add 0.05 g of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride, and then add functionalized polyester containing amino groups 0.5 g of fiber was reacted at 20° C. for 4 hours, and then washed with water to obtain intelligent polyester fiber.

[0049] The above intelligent polyester fiber is woven into intelligent polyester cloth, and its SEM image is as follows figure 1 As shown, it can be seen from this figure that the particles are distributed on the surface of the fiber to obtain a fiber with a rough surface.

[0050] The hydrophilic and hydrophobic properties of the intelligent polyester cloth prepared in this embodiment change under the change of temperature, such as figure 2 As shown, under the condition of lower than 30°C, the contact angle of the smart polyester cloth to water is 109.2°, which has hydrophobic properties; when heated to 80°C, the contact angle of...

Embodiment 2

[0054] Disperse 10mg of N,N'-diethylacrylamide and methylpropanesulfonic acid copolymer particles in 50ml of water, add 0.1g of N-hydroxysuccinimide, and then add 0.5g of aminated polypropylene fiber, at 20°C The reaction was carried out for 4 hours, and then washed with water to obtain intelligent polypropylene fibers.

[0055]The hydrophilicity and hydrophobicity of the intelligent polypropylene fiber prepared in this example change reversibly under the change of temperature: when the temperature rises, its hydrophobicity increases; when the temperature decreases, its hydrophilicity increases.

[0056] The hydrophilicity and hydrophobicity of the intelligent polypropylene fiber prepared in this example change reversibly under the change of pH value: when the pH value increases, its hydrophilicity increases, and when the pH value decreases, its hydrophobicity increases.

Embodiment 3

[0058] Disperse 10 mg of carboxyl-containing polyvinylpyridine particles in 50 ml of water, add 0.1 g of N-hydroxysuccinimide, and then add 0.5 g of aminated carbon fiber, react at 25°C for 4 hours, and then wash with water to obtain smart carbon fiber.

[0059] The hydrophilicity and hydrophobicity of the smart carbon fiber prepared in this embodiment change reversibly under the change of pH value: when the pH value increases, its hydrophobicity increases, and when the pH value decreases, its hydrophilicity increases.

Abstract

The invention discloses an intelligent fiber or a product thereof with environmental responsibility and a preparation method thereof. The intelligent fiber or the product thereof with environmental responsibility is prepared by connecting a fiber body or a fiber product and granules with environmental responsibility by virtue of chemical bonds; and the surfaces of the granules are connected with at least one of the following functional groups: acylamino, pyridyl, a group shown as a formula 1, amino, carboxyl, cyclodextrin, epoxy group, hydroxide radical and adamantly. The granules with environmental responsibility are combined with the fiber so as to obtain a fiber material with environmental responsibility; and a series of intelligent fiber materials with different bodies are prepared. The invention provides an intelligent fiber material with environmental responsibility on multiple environmental factors respectively or simultaneously, an intelligent fiber fabric and a simple and universal preparation method thereof suitable for large-scale production.

Description

technical field [0001] The invention relates to an intelligent fiber with environmental responsiveness or a product thereof and a preparation method thereof, and belongs to the field of fiber materials and products thereof. Background technique [0002] Fiber materials are widely used in various fields such as fabrics, filter materials, catalysis, electronics, etc. However, traditional fibers generally have smooth and uniform surface properties, so the application of fiber materials so far is mainly determined by the properties of the fiber itself. Changes in the hydrophilic and hydrophobic properties of the fiber surface seriously affect its performance. [0003] So far, fiber materials with superhydrophobic, superoleophobic, superhydrophilic or superamphiphilic surfaces have been reported, which have been applied in self-cleaning fibers or fabrics, oil-water separation, biotechnology and other fields. However, the surface with switchable hydrophilicity and hydrophobicity ...
