Fibra de aerogel

Aerogel fiber represents a breakthrough in thermal insulation technology for textiles, combining the world’s lowest thermal conductivity (0.017-0.020 W/m·K) with an ultra-lightweight structure that weighs just 0.003g/cm³. Developed from nanoporous silica aerogel encapsulated in flexible polyester fibers, this innovative material contains over 90% still air, delivering exceptional warmth without bulk. ShowarmX® aerogel fiber outperforms traditional insulation materials like down and synthetic hollow fibers, providing superior thermal efficiency while maintaining breathability and moisture management. From professional mountaineering gear and winter sportswear to thermal underwear and outdoor camping equipment, aerogel fiber is transforming how textile manufacturers approach cold-weather performance. This comprehensive guide explores the science, properties, applications, and advantages of aerogel fiber technology in modern textile design.

What is Aerogel Fiber? Understanding Silica Aerogel Textile Technology

Aerogel fiber represents a breakthrough in thermal insulation textiles, combining nanoporous silica aerogel technology with flexible polyester fibers.

A fibra de aerogel combina a condutividade térmica ultrabaixa do aerogel com a flexibilidade do poliéster. Feito de aerogel de sílica nanoporosa, contém mais de 90% de ar parado, proporcionando isolamento excepcional com condutividade térmica entre 0.017W/mK a 0.020W/mK. Sua densidade é extremamente baixa, 0.003g/cm³, o que o torna leve. As principais características incluem alta absorção de umidade, excelente respirabilidade, forte absorção de odores e facilidade de tingimento. Ideal para casacos de inverno, roupas íntimas térmicas, roupas esportivas, sacos de dormir e barracas, a fibra de aerogel oferece isolamento térmico superior sem volume, perfeita para climas extremos e atividades ao ar livre. Este material inovador combina tecnologia avançada com funcionalidade prática.

How Aerogel Fiber Provides Superior Thermal Insulation

A fibra de aerogel mantém o calor aproveitando sua estrutura nanoporosa, que contém mais de 90% de ar parado. Esta estrutura reduz significativamente a transferência de calor, pois o ar retido atua como um excelente isolante. A condutividade térmica da fibra varia de 0.017W/mK a 0.020W/mK, muito inferior à do ar estático, garantindo isolamento superior. Além disso, a densidade extremamente baixa da fibra de 0.003g/cm³ melhora suas propriedades isolantes sem adicionar volume. Combinada com poliéster, a fibra de aerogel retém o calor enquanto permanece leve, respirável e absorvente de umidade, tornando-a ideal para roupas para clima frio e equipamentos para atividades ao ar livre.

Aerogel Fiber Properties and Performance Benefits

Ultra-Lightweight Design (0.003g/cm³ Density)

At just 0.003g/cm³, aerogel fiber is one of the lightest insulation materials available for textile applications. This ultra-low density means:
– 60% lighter than traditional hollow fiber
– Reduces garment weight without compromising warmth
– Ideal for performance sportswear and outdoor gear

Desempenho excepcional de isolamento térmico

Aerogel fiber’s thermal conductivity of 0.017-0.020 W/m·K delivers:
– Superior warmth-to-weight ratio
– Equivalent insulation of 20-30 layers of ordinary glass in just 1 inch
– Maintains body temperature in extreme cold conditions

Absorção de umidade e respirabilidade

The nanoporous structure provides: – High moisture vapor transmission – Rapid evaporation rate – Prevents overheating during activity – Maintains comfort in varying conditions

Enhanced Dyeing and Odor Absorption

The increased surface area of aerogel fiber enables: – Superior dye uptake and color fastness – Natural odor absorption properties – Easy coloring for diverse design applications

Aerogel Fiber Applications in Textiles and Apparel

ShowarmX® aerogel fiber’s unique combination of lightweight warmth and breathability makes it ideal for demanding textile applications where thermal performance is critical.
