eSUN Advances Bio-Based Blends: PLA Fiber + Viscose, Cotton, Linen, Wool, Rayon from Bamboo

Polylactic acid (PLA) fibers can be blended with cotton, linen, silk, wool, or other bio-based fibers. On one hand, this can help improve the application limitations of single materials; on the other hand, multi-material blends can also endow downstream applications with multifunctionality.

As a bio-based material, PLA fiber has broad application prospects, but it also has certain limitations in specific performance aspects. Through continuous R&D innovation, eSUN has made a series of breakthroughs in PLA fiber application technology, overcoming challenges such as strength degradation and dyeing difficulties. These efforts promote innovation in “bio-based CP” technology and provide the industry with diverse green composite material solutions.

01. PLA Fiber + Viscose Fiber: The “Golden Duo” for Moisture Absorption and Antibacterial Performance

Viscose fiber is derived from natural cellulose and is known for its outstanding moisture absorption and breathability; PLA fiber is sourced from renewable plant resources. The combination of the two brings significant advantages. After blending, the product not only improves moisture absorption, breathability, and quick-drying performance, but also enhances antibacterial properties. Tests show that a blend of 30% PLA and 70% viscose achieves an antibacterial rate of over 80% against common bacteria. Its applications are extensive, ranging from antibacterial hygiene materials to eco-friendly packaging and skin-friendly clothing, fully meeting market demands.

02. PLA Fiber + Wool: A Revolutionary, Breathable, Eco-Friendly Fabric

While wool is warm and skin-friendly, it is prone to deformation. Blending it with PLA fiber allows for complementary advantages. The resulting fabric combines warmth and quick-drying properties, as well as antibacterial and mite-resistant features, making it suitable for close-to-skin garments. It also enhances garment structure and reduces costs. From knitted sweaters to suit fabrics, this blend demonstrates exceptional performance.

03. PLA Fiber + Linen Fiber: A Sustainable Development Model Where 1+1>2

Linen fiber is strong but has a rough texture. When blended with PLA fiber, it enables lightweight and eco-friendly solutions in automotive interiors; in packaging, it avoids the introduction of irritants; in clothing and home textiles, it combines antibacterial and breathable properties. It can even be used in home wall panels, showing broad application prospects.

04. PLA Fiber + Rayon from Bamboo: A Skin-Friendly and Antibacterial “Buffed-Up” Combo

Rayon from bamboo is naturally antibacterial. When blended with PLA fiber, the antibacterial performance is further enhanced. A sample blended with 40% PLA and 60% rayon from bamboo achieves an antibacterial rate of up to 99% against certain bacteria. At the same time, moisture absorption and breathability are optimized. This blend is widely used in hygiene products, sportswear, and home textiles.
