The functionalization of textiles adapts to the changes of people's lifestyles and the pursuit of health, comfort, and value-added expectations. It provides more choices for people's perfect life. It is the direction of technological advancement of textile products, and is to improve the grade and added value of textile products. One of the effective ways.

In recent years, with the advancement of science and economic development, the variety of functional textiles has increased, and the functional textile industry has rapidly developed into an important high-tech industry.
This article introduces several new functional textiles and their applications, as a reference for everyone to purchase and use.
Negative ion textile
The significant impact of negative ions on human health and ecology has been verified by clinical practice at home and abroad. Negative ions, such as human health, play an important role, such as the elimination of active acid in the human body, eliminating fatigue, activating cells, enhancing immunity, and improving sleep.
The production principle of negative ion textiles is to add negative ion finishing agent in the production process of fibers or in the finishing stage of fabrics. The produced textiles containing negative ion finishing agents release negative ions continuously when they are in contact with air, water and gas.
The negative ion garment made of this fabric directly contacts the human skin, and a negative ion air layer can be formed between the skin and the clothes to exert the health effect of negative ions. In addition to its application in the field of clothing, negative ion textiles also have broad application prospects in both decorative textiles and medical and sanitary textiles.
Moisture wicking textile
Also known as moisture-absorbing and quick-drying textiles, the moisture absorption, quick-drying and perspiration performance of the fabric are characterized by the adsorption capacity of the textile (fabric) on water, the evaporation rate of moisture on the fabric, and the moisture permeability.
The production of moisture wicking textiles is based on the use of moisture wicking fibers for physical and chemical modification of Polyester fibers; the second is the moisture absorption and quick drying of textiles.
Moisture wicking textiles are mainly used in sportswear, casual wear, underwear and other apparel. Because it can solve the problem of stuffy heat and sweat sticking, it can adjust the inner climate of the garment, so that the garment has the characteristics of “breathingâ€, so it is also called “breathing textileâ€.
Far infrared textile
Far-infrared textiles are short for a class of textiles with efficient far-infrared emission properties. Far-infrared rays are easily absorbed by the human body. It not only causes thermal effects on the surface of the skin, but also causes resonance through molecules, which causes deep tissue heat in the skin. This action can stimulate cell activity, improve blood microcirculation, and improve immunity of the body. Force, play a series of health care functions.
Far-infrared textiles are materials that can absorb external energy (including light energy and human body heat) and can efficiently emit far-infrared materials during the finishing process or fiber molding process, or adhere to the textiles at a wavelength of 4-20 μm. There is a high far-infrared emissivity (≥65%) in the range.
Far-infrared textiles can be used to develop health-care products and medical supplies such as warm clothing, underwear, bedding (sheets, blankets, etc.), cushions, knee pads, belts, health shoes and socks.
Anti-electromagnetic radiation textile
With the development of economy and technology, the application of facilities and equipment with electromagnetic radiation is inevitable. Electromagnetic radiation is colorless, odorless and intangible. It is a kind of pollution phenomenon that cannot be sensed by the senses. It is known as the "invisible killer" and "high-tech pollution" of human beings. The World Health Organization believes that among all kinds of pollution, the threat of electromagnetic radiation is the biggest, which seriously affects public health and the ecological environment.
Anti-electromagnetic radiation textiles use special techniques and special processes to organically combine anti-electromagnetic radiation materials (usually metal materials) with textile fiber materials to reflect and shield electromagnetic waves. Generally, the shielding performance requirement is over 95%, and the textile also has antistatic properties.
At present, anti-electromagnetic radiation textiles that have appeared on the market mainly include metal wire anti-electromagnetic radiation fabrics, electroless anti-electromagnetic radiation fabrics, and coating anti-electromagnetic radiation fabrics, which can be applied to field care products (tents, clothing), interior decoration fabrics. , maternity wear, industrial protective clothing and industrial protective dressing materials and military aspects.
UV protection textile
In recent decades, due to the increase in human activities, especially the use of Freon, the ozone layer around the Earth has created voids, which have led to a rapid increase in ultraviolet radiation on the Earth's surface, which has led to an increase in the incidence of human skin cancer, which has seriously affected Human health.
National Standard GB/T18830–2009 “Evaluation of UV Protection Performance of Textiles†stipulates that when the UV protection coefficient of textiles is UPF>40 and the ultraviolet transmittance T(UVA)<5%, it can be called UV protection products. UV-resistant textiles can effectively prevent or reduce the damage of ultraviolet rays to the human body. UV protection textiles currently have two production routes:
(1) Textiles are spun directly in a conventional manner using UV-resistant fibers. The key to this method is the UV resistance of UV-resistant fibers. At present, the production of anti-UV fiber is made by mixing inorganic ceramic micropowder with polymer chips, preparing masterbatch and then spinning or fiber-forming polymer in the polymerization process, adding inorganic ceramic micropowder in molten state or having ultraviolet shielding property. These substances can strongly absorb ultraviolet rays having a wavelength between 280 nm and 400 nm.
(2) The functional finishing technology is adopted, that is, the method for coating the anti-UV finishing agent and the textile are firmly combined.
The anti-UV textiles currently on the market include outdoor sportswear, anti-UV shirts, parasols (parasols), curtains and tents.
Nano textile
Known as “Nanotechnology for the treatment of textilesâ€, the application of nano (1 nm “10-9 m†technology to the fabric during the production process of the product or its specific parts, so that the textile has antibacterial, waterproof, oil-proof and easy decontamination. One or several functions such as UV resistance.
The application of nanotechnology in the textile field has entered a stage of growth. At present, there are two kinds of processing methods. One is to fill the fiber into the fiber to modify the fiber and improve the fiber's function. The other way is to apply the coating. Layer finishing techniques form nanoscale particles on the surface of the fabric.
Nano-textiles are versatile and widely used in clothing, medical, food and beverage, military and other industries. In the field of clothing, there are already sales of nano shirts, T-shirts, hats, casual wear for men and women on the market. In December 2009, the implementation of the national standard GB/T22925–2009 “Nanotechnology Processing Apparel†standardized the application of nano-textiles in the field of clothing.
