Why can Qingfeng aerogel fiber replace down?

The aerogel composite fiber, which is a breakthrough research and development achievement of Qingfeng Chemical Fiber, adopts the world’s leading compatible polymerization technology. It evenly combines nanoscale aerogel particles with high-strength polyester fibers at the molecular level to form a dense three-dimensional thermal insulation network. The aerogel content reaches 3%, and the volume proportion exceeds 35%. A stable “micro-airbag” is formed inside each fiber, completely getting rid of the defects of easy peeling off and easy cracking in the traditional coating process, and achieving a perfect balance between the mechanical strength of the material and the thermal insulation performance.

Qingfeng aerogel fiber has six core advantages, comprehensively surpassing down.

1. Ultra-light and heat-locking: The thermal insulation performance is equivalent to that of 90% down
   Aerogel has a nanoporous structure, and its thermal conductivity is as low as 0.016 W/m·K (only 70% of that of air). The pores are filled with air, forming an efficient thermal insulation barrier. The nanoscale size of the internal pores also restricts air convection and greatly reduces the efficiency of convective heat dissipation. As measured by a domestic authoritative laboratory, the aerogel cloud down using aerogel fiber as the material has a thermal insulation rate of 86.8% and a clo value of 4.03. Its thermal insulation performance is equivalent to that of top-grade down with a down content of 90% (a fill power of over 800), while the weight is reduced by 40%, completely solving the problem of the bulkiness of down jackets.
2. Anti-moisture revolution: Still warm as spring in the rain
   Traditional down loses 70% of its thermal insulation performance when it clumps together after getting wet. However, Qingfeng aerogel fiber has a natural hydrophobic property and still maintains an insulation efficiency of over 98% even after being soaked in water. The closed air hole structure inside the fiber isolates the penetration of water molecules, continuously locks in the heat in a humid environment and in rainy and snowy weather, and greatly enhances the protection ability for outdoor sports and in extreme climates.
3. Never shedding down: Lasting protection as good as new after ten years
   Through the “aerogel-polyester molecular bonding” technology, the structural stability of the fiber is increased by 300%, the number of times it can withstand bending exceeds 100,000 times, and the attenuation of its thermal insulation performance is less than 3% after being washed 50 times. The one-piece molding design eliminates the trouble of down leakage in down jackets, and it is especially suitable for children’s clothing, people with allergies, and high cleanliness scenarios.
4. Extreme compression: A miracle of lightness and warmth that can be stored with one palm
   The aerogel fiber is lighter than down and also has super strong resilience. It can restore more than 95% of its original volume within 30 seconds after compression, and its volume storage efficiency is three times higher than that of down. The light and thin characteristics enable winter coats to get rid of the “Michelin” shape, and it can cover all scenarios of fashionable items such as business suits and light outdoor jackets.
5. Environmental protection pioneer: A sustainable choice for the future
   Each piece of clothing made of aerogel fiber reduces the use of about 200 grams of down raw materials (equivalent to the down amount of 2 geese), reduces carbon emissions by 35% during the production process, and can be 100% recycled. It conforms to the carbon neutrality strategies of global leading brands and helps to upgrade the green industrial chain.
6. Cost innovation: High-end performance at a popular price
   The price of Qingfeng aerogel fiber is affordable, which is less than one-tenth of that of down, and there is no risk of raw material price fluctuations in different seasons, providing brand owners with a stable supply chain guarantee.
   Qingfeng aerogel fiber is not only a material revolution but also a deep response to the human need for warmth. It reshapes the daily wearing experience with aerospace-grade thermal insulation technology, conquers extreme cold with a weightless posture, and makes winter clothing say goodbye to bulkiness and restrictions from now on.
