Typical introduction of Smart Textile

Author: Released in:2023-03-14 Click:19

According to the existing reports and studies, typical smart textiles products mainly fall into the following categories:

(1)Electronic information Smart textiles The perfect combination of strong>product microelectronics information technology and textile technology has led to electronic information intelligent textiles. Strictly speaking, this kind of textile is characterized by the detection or processing of various information through multiple information processing systems, which is just a combination of multiple subsystems; it is a collection of multi-functions and still maintains the level of intelligence of functional materials, which is a negative product Smart textiles.

(2) Color-changing textiles

Color-changing materials refer to fabrics whose color changes with changes in the external environment. The basic principle of material discoloration is that when the matchCircumstantial external conditions change, the visible light absorption spectrum of the material changes. The color-changing material is essentially a color-changing dye or pigment obtained by copolymerizing a monomer having a color-changing function with other monomers or introducing it as a side group. According to the external reaction conditions, the color-changing materials can be divided into photochromic, thermal, electrochromic, pressure-sensitive and moisture-sensitive color-changing materials.

(3) Phase transition materials and intelligent temperature control textiles

According to different temperatures, the phase state of matter can change, that is, solid-liquid, solid-gas, gas-liquid During a phase transition, a substance absorbs heat from the environment or gives off heat to the environment. Phase transition materials are substances that can undergo phase transitions with changes in ambient temperature.

(4) Shape-memory polymer materials and textiles

Shape-memory polymer materials refer to products with a particular original shape. A class of materials that can automatically return to their original shape, mainly heat-sensitive polymer materials with shape memory, that is, their shape and performance can cause predetermined reactions after being stimulated by external temperature. This type of polymer has a two-phase structure, consisting of a stationary phase that retains its original shape and a reversible phase that can reversibly fix and soften with temperature changes.

(5) Hydrogel-based smart textile

Hydrogel is a cross-linked structural swelling formed between polymer chains in the form of chemical bonds or physical forces. The composite system consisting of water and polymer network is a kind of intelligent material. An important feature of hydrogels is that they undergo volume phase transitions under certain environmental stimuli, that is, when the external environment changes continuously, the gel volume changes continuously. According to different stimuli, smart hydrogels can be divided into pH-responsive, temperature-sensitive, light-sensitive, electric field-responsive and magnetic field-responsive, etc.

(6) Stealth textile materials based on artificial periodic structures

Strictly speaking, stealth materials belong to the category of metamaterials, which are artificial structural materials. Textile fibers themselves have micron-scale diameters, and it will be exciting to engrave periodic structures on a smaller scale to obtain textile fibers with negative refractive index effects, which can achieve true stealth. they become invisible.
