The world of textile fibers is always undergoing rapid changes, and my country, as a major country in textile and garment production and processing, is always the first to feel this change. Recently, an aerogel fiber with remarkable characteristics such as extremely high porosity and ultra-low density has become a dazzling new star in my country's textile fiber family.
Ki sa ki fib èrgel?
Fib Airgel se yon nouvo kalite fib fonksyonèl rad, ki gen karakteristik bon retansyon chalè, igroskopisite ak rèspirabilite. Sa yo rele -fib èrgel, jan non an sijere, refere a materyèl fib pou twal ak rad ki fèt ak aerogel. Kòm nou tout konnen, yon jèl se yon solid elastik nan ki patikil koloidal nan yon sol oswa yon solisyon fòme yon estrikti rezo espasyal anba aksyon an nan yon mwayen dispèsyon. Avèk dlo kòm mwayen dispèsyon, li rele idwojèl; ak gaz kòm mwayen dispèsyon, nou rele li aerogel.
Aerogel is the smallest known solid material in the world. Because most of its internal components are gas, it looks like a cloud. Therefore, aerogel is also called "solid smoke". The birth of aerogel stems from the idea of scientists with open brains to replace the water in jelly (hydrogel) with gas.
Air is the best thermal insulation material. For example, the bulkiness of down is an important criterion for testing its quality. More than 90 percent of the aerogel is air, so the aerogel fiber has extremely high thermal insulation properties. According to the relevant experimental data, the thermal insulation value of polyester aerogel fibers far exceeds the national standard extremely low thermal conductivity: Less than or equal to 0.02W/(MK).
At the same time, aerogel fibers also have the characteristics of light weight. Because the specific gravity of aerogel is very light, between 10-30 kg per cubic meter, the aerogel yarn is actually very light. Compared with ordinary consumption fiber, its thickness is only one-half, and the density is as low as 0.003 grams per square centimeter.
In addition, the aerogel fibers are filled with nano air masses, and the specific surface area of the fibers is much larger than that of the porous hollow superfine fibers. It has good hygroscopicity and good air permeability, and is convenient for the downstream printing and dyeing of the industrial chain.
Itilizasyon Fib èrgel
Aerogel fibers with extremely high thermal insulation, moisture absorption and breathability are also widely used. Obviously, it is used to make cold-proof clothing, sportswear, etc. With the further development of textile fiber technology, products made of aerogel fibers, such as part of space suits, can be applied to the aerospace field.
People who like outdoor sports, mountain climbing, adventure, and crossing can not avoid their own safety issues in the complex environment in the wild, especially in low temperature conditions. According to laboratory data, the thermal insulation performance of aerogel fibers is 2.8 times that of cotton cloth at low temperatures, and its enthalpy value can reach 162 J/g, which can be used in extreme environments ranging from minus 196 degrees Celsius to plus 300 degrees Celsius. Long-term use of thermal insulation performance. The aerogel fibers developed by Qingdao Zhenghongxiang Technology Co., Ltd. are processed into cold-proof clothing, which can also play a role in keeping warm in extremely cold temperatures.
At the same time, the extremely high thermal insulation, moisture absorption and breathability of aerogel fibers are also very suitable for application in thermal underwear and other products. The biggest problem with ordinary thermal underwear is that it is warm but not breathable. When entering the room from the outdoors in winter, the moisture generated by the human body is difficult to discharge after the temperature rises, resulting in a significant reduction in the wearing comfort of the user. However, the aerogel fibers produced by Qingdao Zhenghongxiang Technology Co., Ltd. can perfectly solve the above problems.
Aerogel fibers are widely used, in addition to outdoor clothing and thermal underwear, they can also be used in body armor, tents, sleeping bags, knee pads, yoga clothes and other fields.
