Polyacrylonitrile fiber: Characteristics and applications suitable for Frost Descent clothing/Home Textiles/outdoor needs!

After the Frost's Descent, the temperature continues to drop, and the temperature difference between day and night increases. The dry air and low-temperature environment put forward higher requirements for the warmth retention and comfort of materials. Polyacrylonitrile fiber (commonly known as "acrylic") has become a practical material suitable for various scenarios during the Frost Descent period due to its own characteristics. Its features and applications can be analyzed in combination with the demands of the solar term.

The core characteristics of Polyacrylonitrile fibers are highly compatible with the requirements of the frost descent scene. Firstly, it has outstanding thermal insulation. The internal structure of the fiber is porous, which can store a large amount of still air and effectively prevent heat loss. Its thermal insulation effect is close to that of wool, and the material is light. After being made into clothes, there will be no sense of heaviness or oppression, which meets the wearing needs of "warmth without bulkiness" after the Frost's Descent. Secondly, the moisture absorption and breathability have been optimized. Although the moisture absorption rate of traditional acrylic is relatively low, the improved polyacrylonitrile fiber, through process adjustment, can absorb a small amount of moisture on the skin surface and quickly evaporate it, avoiding the discomfort caused by static electricity in dry weather and enhancing the wearing comfort. Thirdly, it has strong weather resistance and stability. In the environment of low temperatures in the morning and evening (-5℃ to 10℃) and daytime temperature fluctuations after frost's descent, the fibers are not prone to brittleness or deformation, nor will they mold due to humidity changes. They can maintain stable performance even after long-term use.

The application scope is deeply compatible with the scene requirements after the frost's descent. In the field of clothing, Polyacrylonitrile fibers can be used to make warm sweaters, fleece jackets, scarves and gloves. The combination of warmth retention and soft hand feel makes them suitable for daily commuting and outdoor walks after the Frost's Descent. In the home textile field, it can be made into autumn and winter blankets and bedding sets. The porous structure's thermal insulation performance enhances the warmth of sleep at night, and the improved moisture absorption property can also reduce the static electricity trouble in dry weather. In the field of outdoor products, it can be used to make outdoor fleece inner linings and sleeping bag linings. Its low-temperature resistance enables it to continuously provide warmth and protection in outdoor camping and short-distance hiking scenarios after frost's descent. In the industrial field, some high-strength polyacrylonitrile fibers can also be used to make insulation cloth for agricultural greenhouses
