In a critical moment, how do textile people use high technology to protect "the most beautiful retrogrades"?

On March 30, a forest fire broke out in Lier Village, Yalongjiang Town, Muli County, Liangshan Prefecture, Sichuan Province. In the action of the rescue, affected by the sudden change of wind and wind, the sudden explosion of forest fires, a huge fireball was formed instantly, and the fire-fighting personnel at the scene urgently avoided the danger, but 27 forest firefighters and three local firefighters lost contact.

After full search and rescue, the lost joint personnel have all found, 27 forest firefighters and three local cadres and masses have died, including Yang Dawa, director of the Muli County Forestry Bureau, and another staff member of the bureau.

Nowadays, firefighters have become "the most sacrificed professions in the peacetime." Their "most beautiful retrograde" in times of crisis is moving. They have shaped countless lives to protect the lives and property of the people and at the cost of youth and life." Uncommon "and" great. Beyond being touched, can we have better technological means to protect their lives at the height of the fire, so that the possibility of sacrifice is minimized?

The emergency industry is closely related to industrial textiles and involves many areas of the industry. For example, most of the products for safety protection textiles are emergency products. Fire service suits, explosion-proof suits, and stab-resistant cut-proof garments are all necessary for firefighters and special police.

Whenever a major fire accident occurs, the firefighter will wear the fire service if he wants to enter the accident site. Therefore, firefighters--the firefighters wear protective clothing to protect themselves from harm when working on a major fire accident site, which is the most important safety equipment for firefighters. The stronger the function of the fire service, the better the protection of the firefighter.

How do textile people escort firefighters?

For textile and garment enterprises, it is an unswerving pursuit to continuously enhance the functions of fire-fighting clothing, such as heat-insulating and flame-retardant through technology. It is also a responsibility on the shoulders.

Due to the ever-changing fire scene, the number of rescues and rescues has increased. Firefighters need to wear different battle suits in the face of different situations. For example, thermal insulation suits, heavy chemical protective suits, light chemical protective suits, electrical insulation suits, emergency rescue suits, and what we call fire-fighting protective clothing.

Fire service is one of the important equipments to protect the personal safety of firefighters active in the first line of fire protection. It is not only an indispensable essential for fire rescue sites, but also a fire protection device to protect firefighters from injury. The most common firefighter costumes for people at the fire scene.

What material is the fire service made of? Why can it play a role in fire prevention? Is it different from the clothes that our ordinary people usually wear?

For firefighters, firefighting suits made of aramid can meet the requirements of various indicators. Aramid itself has a unique molecular structure, which can effectively flame retard, heat and wear without chemical treatment. Moreover, these properties do not decrease with the increase of wearing time and washing times, and can be widely used in protective clothing, protective gloves, etc. Personal protective equipment. Moreover, the wearing is more comfortable and breathable, which can greatly reduce personal injury and effectively protect the life safety of firefighters.

The garment made of Temeta meta-aramid and Taipulon para-aramid has excellent properties such as high temperature resistance, intrinsic flame retardancy, tear resistance and antistatic, which can effectively reduce the damage of deflagration and arc and improve the applicability of clothing. To meet the protection needs in high-risk environments, it has been widely used in the field of personal protection such as petroleum and petrochemical, chemical, and electric power.

Fireproof fabric to reduce or avoid fire accidents burns and damage

In terms of fireproof fabrics, Beijing Sauerland Flame Retardant Fiber Co., Ltd. has recently developed SOL FR new three-proof fabric. It is understood that the fabric is blended with other high-performance flame-retardant fibers by SOL FR. It is a high-performance fabric developed by downstream textile companies with anti-heat radiation, anti-splash and anti-arc function.

According to the company's deputy general manager Qi Guoqing, this fabric is made of SOL FR regenerated cellulose fiber and a variety of high-performance flame retardant fiber materials. It is twill weave, the weight is 240g/m2, and the fabric is light yellow. It can dye orange, orange, dark green and other colors. The materials are all permanent flame retardant materials. Through synergistic interaction, this fabric has excellent anti-heat radiation, anti-splash and anti-arc protection, and has antistatic, antibacterial and comfort properties.

The protective principle of the flame-retardant workwear is mainly to shield the workers from heat, reflection, absorption, carbonization and the like to protect workers from open flames or heat sources. Among the fabrics used in the flame-retardant workwear, the flame-retardant fiber greatly slows down the burning speed of the fiber, and extinguishes itself immediately after the fire source is removed, and the burning part is rapidly charred without melting, dripping or hole-piercing, giving time. Evacuate the scene of the fire or take off the clothes burned on the body to reduce or avoid burns and burns for protection purposes. This is of great significance for reducing or avoiding burns and damage from fire accidents, and is widely used in the industrial field.

The new fabric is mainly made of SOL FR and other flame retardant fiber materials, has good long-term flame retardant properties, and is comfortable to wear (moisture permeability ≥9000g/m2·24h), antistatic, antibacterial, dyeing performance, It can provide effective protection in a variety of industrial protection fields and military applications.

Fireproof fiber, greatly improving the performance of special protective clothing

In terms of fiber, fiber companies are also relying on the development of new materials to ensure the excellent performance of flame-retardant functional fabrics. As a well-known high-performance fiber material which has been industrialized in recent years, polyimide fiber has been attracting attention due to its excellent comprehensive performance, especially its flame retardancy, high temperature resistance and corrosion resistance. However, due to its production cost and the difficulty of synthesis and forming process, its research and development and marketization progress are relatively slow. In terms of research and development and innovation of polyimide fiber, the industrialization process of Jiangsu Aoshen New Materials Co., Ltd. is very representative.

Ao Shen Xincai is a national high-tech enterprise specializing in the research and development and production of high-performance polyimide fiber and its downstream products. In 2013, Aoshen's world's first thousand tons of dry-spun polyimide fiber The production line was completed and put into production. In 2015, the original liquid colored polyimide fiber was first created. In 2017, the high-strength model polyimide fiber was successfully developed.

What breakthroughs did Ao Shenxin made in the research field of polyimide fiber? Tao Mingdong, general manager of the company, said that in the aspect of fiber research and development, Ao Shen New Materials and Donghua University have broken through the key technologies of polyimide fiber dry spinning. The new technology of "reaction spinning" developed by the company is the world's first. It is with the research results of this technology that Aoshen Shinki completed the construction of the first heat-resistant 1000-ton dry-spun polyimide fiber production line and successfully put into production.

The reporter learned that the color fastness of the pigmented polyimide fiber reaches 4-5, which is very suitable for making flame retardant protective clothing and high-grade flame retardant fabric. In short, its excellent comprehensive performance can greatly improve the performance of special protective clothing.

In recent years, Ao Shen has developed high-performance filter materials, and developed special protective fleece fabrics such as polyimide, new fire-fighting protective clothing for polyimide firefighters, polyimide special warheads, and polyimide warming. , Polyimide fire blanket, polyimide antibacterial warm socks, polyimide insulation gloves and other flame retardant protection products, and cooperated with relevant military research institutes to develop regional combat suits, special anti-resistance for solid rocket motors Products such as ablative fiber, special cable sheathing, high-performance machine-reducing rescue ropes have enhanced the core competitiveness of key areas such as environmental protection , national defense, and aerospace.

Tao Mingdong said that technological innovation has only a starting point and no end. Accelerating the promotion of China's independent research and development production materials in the national defense industry, aerospace, environmental protection industry to get more applications, in order to achieve the company's own economic value and social value, to make a contribution to building a strong country. In order to meet the growing demand for polyimide fibers in different fields, Aoshen Shinki has formulated a development plan for the next three to five years, based on the world's first industrially produced dry-spun polyimide production process technology. Fiber modification research, process technology optimization and product application development were carried out, and a differentiated polyimide fiber production line with an annual output of 3,000 tons was built.

Lightweight fire fighting suits provide comfort for rescue

In fact, the continuous optimization of the fire service by the textile people is not only reflected in its functionality. In order to ensure the comfort of the fire service, Beijing Bangwei Company has also carried out useful explorations on the lightweight of the fire service.

The reporter learned that Bonvi took the lead in developing a three-layer fire service material, which reduced the weight of the garment and improved the protective performance, and occupied a dominant position in the fire service market. Today, Bonwe has formed seven major categories in the military, fire, special police, industrial and health emergency areas: military supporting textiles, nuclear and biochemical protection (NBC), fire special police and industrial safety, special industry protection, health emergency protection, Flexible composite materials and products, individual protective materials and equipment.

Bonvi's mission is to "meet the demand for industrial textiles for new textile materials." It is precisely this kind of mission and responsibility that Bangwei can always mobilize and respond quickly during critical moments of major national equipment development and major events. And make timely contributions.

After the "8.12" Tianjin explosion accident, Bangwei's three products were applied to the first-line disaster relief forces: the light protective clothing system equipped by the National Nuclear and Biochemical Rescue Force, and the light chemical protective clothing worn by experts, especially the emergency large-scale shelter. It provides security for the collective protection of rescue officers and soldiers in complex environments.
