Derong underwear fabric

Derong underwear fabric is actually a functional thermal material. Its full name is “German Bayer Acrylic Fleece,” often referred to as “warm fleece” or “heat-generating fleece.” It is a new fiber developed from standard acrylic, featuring distinct characteristics:

Key Features

Exceptional Insulation: The high loft of De Rong fibers traps air between strands, creating an insulating layer that provides greater warmth than standard cotton or polyester.

Lightweight Comfort: The fabric is featherlight, eliminating any heavy, constricting feel and allowing unrestricted movement.

Moisture-Wicking Heat Generation: Certain De Rong fibers possess moisture-wicking and heat-generating properties, absorbing moisture from the body and converting it into warmth.

Soft and Skin-Friendly: Features a fine, velvety surface with a smooth feel, gentle against the skin even when worn next to the body.

Good Elasticity: Often blended with spandex, providing excellent recovery and resistance to deformation.

Easy Care: Resistant to pilling and fading, durable even with machine washing.

Suitable Scenarios

Ideal for autumn/winter thermal underwear, loungewear, base layers, and other close-fitting garments.

Its excellent warmth without bulkiness also makes it popular as a thermal layer for sports.

Selection Tips

Check Composition: Higher German fleece content (generally ≥50%) offers superior warmth. Also note whether spandex is included (for added elasticity).

Check Weight: Higher weight indicates thicker fabric and stronger warmth, suitable for severe cold regions.

Feel the Texture: High-quality German fleece has a fine, even pile without roughness or hard lumps.

Test elasticity: Quick recovery after stretching indicates optimal spandex content, ensuring durability and resistance to deformation.

Check labels: Authentic German fleece fabrics will specify “German Bayer Acrylic Fiber” or “German Fleece” in the composition, helping you avoid low-quality imitations.
