Light heat storage, temperature retention, antibacterial fiber, light heat storage filament polyester nylon yarn heat surge.

Traditional cold-resistant textile products often rely on heavy fillings such as down, wool, or synthetic fibers to achieve thermal insulation. In recent years, however, an increasing number of new thermal materials have been applied in the manufacturing of cold-resistant textiles. These materials not only offer excellent warmth retention but also come with advantages such as being lightweight, eco-friendly, and easy to care for, providing consumers with more diverse choices. So, against the backdrop of the rise of new materials, will cold-resistant textile products truly undergo a transformation where "non-down" becomes essential?

Cold-Resistant Thermal Materials Comparable to Down

Shandong Xiyou Technology Development Co., Ltd. (Xiyou High-Tech) has launched a new high-quality light-absorbing, heat-trapping, and antibacterial fiber product—AIREPAI Thermal Wave®—specifically developed and designed for the field of technologically advanced cold-resistant textiles. This innovative product uses modified polyester fiber as its base material and features a unique 360° nano-porous cross-section and a heterogeneous mesoporous structure. The nano-porous structure of this fiber effectively forms air pockets, allowing its thermal performance to rival that of down of the same weight (as per GB/T11048-2018 test results).

Thermal Wave® light-absorbing, heat-trapping, and antibacterial fiber leverages the technological cold resistance, thermal insulation, and ultra-light characteristics of aerospace material silica aerogel—known for its low density, low thermal conductivity, and high porosity. Combined with the patented "heat stress-assisted herbal temperature-resistant extraction" technology, it incorporates the unique full-spectrum visible light absorption and photosynthesis properties of specific plant carbonyl active components. This enables efficient conversion of light energy into thermal energy and achieves a dual effect of micro-nano layered porous heat accumulation and thermal insulation. It is a technologically advanced thermal material that integrates cold resistance, heating, heat storage, and antibacterial properties, offering excellent warmth retention and comfort for clothing and cold-resistant textiles, along with natural eco-friendly characteristics.

Integrating Light Absorption, Heating, Heat Accumulation, Thermal Insulation, and Long-Lasting Antibacterial Properties

Light Absorption and Heating

During the preparation of AIREPAI Thermal Wave®, plant carbonyl active components are added, utilizing their unique full-spectrum visible light absorption capability to achieve efficient conversion of light energy into thermal energy. This gives the material excellent light-absorbing and heat-storing properties, with authoritative testing showing a maximum temperature increase of up to 10.2°C.

Heat Accumulation and Thermal Insulation

Air is the best thermal insulation material. Over 90% of the aerogel consists of 10-30 nanometer static air clusters, providing exceptional thermal insulation and heat retention properties, along with strong far-infrared radiation and heating characteristics.

Long-Lasting Antibacterial Properties

AIREPAI Thermal Wave® contains abundant plant-based herbal active components, giving it excellent natural antibacterial performance. Authoritative testing institutions have confirmed that it still meets the national AAA antibacterial standard even after multiple washes.
