What kind of fleece is the warmest for warm pants

Down, cashmere, camel hair, acrylic fiber, and wool have better insulation effects in warm pants. Down has high fluffiness and is lightweight, cashmere is soft and skin friendly, camel hair has strong moisture absorption, acrylic fiber is low-cost and easy to maintain, and wool has good breathability.

1. Down filled thermal pants achieve efficient insulation by locking in the air layer through a fluffy structure, suitable for sub zero temperature environments. Its velvet structure can store a large amount of still air, with a lower thermal conductivity than other materials, and is lightweight without being bulky. The oil layer of waterfowl fluff has a certain degree of waterproofing, but it is important to avoid frequent machine washing that can damage the structure of the fluff.

2. Cashmere

The surface of cashmere fibers is covered with scales to form a natural insulation layer, and the hollow structure of a single fiber enhances warmth retention. Its fiber diameter is only 14-16 microns, and it feels three times softer than wool, making it suitable for direct skin contact wearing. However, pure cashmere is prone to pilling and deformation. It is recommended to choose a style containing 15% -30% blended spandex to enhance durability.

3. Camel Velvet

The bimodal camel Velvet fiber has a unique microporous structure that can quickly absorb and evaporate sweat, maintaining continuous warmth in a dry state. The wax layer on the fiber surface can withstand temperatures as low as minus 40 ℃, and natural pigments make it unnecessary to dye, reducing the probability of allergies. The coarse and hard scale structure should be used in conjunction with the inner lining to avoid itching.

4. Acrylic

synthetic fibers achieve low-cost insulation by mimicking the structure of wool, and the higher the fiber curl, the stronger the insulation. Specially processed acrylic fibers with irregular cross-sections can reflect human body radiation heat, and the hollow fiber design further enhances insulation efficiency. Suitable for making thick leggings, but static electricity issues require the use of anti-static agents.

5. Wool

The natural curling of Merino wool fibers forms an insulation chamber, which has better moisture absorption and heat generation performance than most natural materials. The hydrophilic groups on the surface of fibers can adsorb water molecules and release heat, making them suitable for cold environments with high humidity. It is recommended to choose ultra-fine wool below 19 microns and undergo anti shrinkage treatment to avoid felting deformation.

When choosing thermal pants, environmental temperature and activity scenes should be considered. For static warmth, down or cashmere is preferred, while dynamic sweating environments are suitable for camel hair or wool. Pay attention to the filling amount or weight index. Down should have a velvet content of 90%, and cashmere content is recommended to be above 30%. Daily care should avoid high temperature drying. Wool and cashmere should be hand washed with neutral detergent, and acrylic products should avoid using softeners to prevent a decrease in electrostatic protection effect. individuals with special constitutions should undergo material allergy testing before wearing it for a long time.
