eSUN to Showcase PLA Fiber and Non-woven Fabric at FILTECH 2026

From June 30 to July 2, FILTECH 2026, the world’s most influential filtration and separation technology exhibition, will grandly open in Cologne, Germany.

eSUN will showcase its core series of products—Polylactic Acid (PLA) fiber and non-woven fabric products, bringing green solutions that are “derived from nature, return to nature.”

Advantages of PLA Filtration Media

PLA filtration media can combine the inherent performance advantages of PLA materials with the structural characteristics of non-woven fibers, such as being ultra-fine, having a large specific surface area, and high porosity, to achieve better filtration performance.

Physical and Biological Dual-Effect Filtration: Excellent Biosafety

PLA fibers are naturally antibacterial, non-toxic, odorless, and non-irritating. In filtration application scenarios, they can achieve not only “physical filtration” but also “biological filtration,” further optimizing the filtration effect.

Firm Structure and Easy to Fold: Adaptable to Differentiated Filtration Application Scenarios

PLA non-woven fabrics possess high mechanical strength. For filtration products that need to be formed by “folding (pleating)”, PLA filtration media can provide perfect support, maintaining the pleated structure for a long time without collapsing.

Ultra-Low COD Value: Making Water Filtration Applications More Environmentally Friendly and Energy-Saving

In water filtration scenarios, the COD (Chemical Oxygen Demand) value of PLA fiber non-woven fabrics is lower than that of similar petroleum-based products. This characteristic makes it extremely friendly to water bodies in water treatment and industrial liquid filtration applications, achieving the dual goals of environmental protection and energy conservation.

Customized PLA Fiber Performance: Enlarging Filtration Space and Improving Filtration Efficiency

eSUN can customize PLA fibers with different resilience, providing the filtration substrate with sufficient filtration space and improving filtration efficiency.

Bio-based and More Environmentally Friendly

Compared with traditional petrochemical plastics, the carbon emissions of PLA materials throughout their entire life cycle are significantly reduced. After the products are used, they can also naturally degrade or be processed through industrial composting, alleviating pressure on the ecosystem.

Empowering Diversified Filtration Scenarios

At the FILTECH 2026 site, we will demonstrate the application potential of eSUN PLA materials in the following core scenarios:

• Air and Gas Filtration: High-end masks and personal protection, primary and medium efficiency filtration in HVAC (Heating, Ventilation, and Air Conditioning) systems, household air purifiers, fresh air filtration for new energy vehicle cabins, etc.
• Liquid and Food Filtration: Drip coffee filter paper, high-end pyramid tea bags, industrial water treatment filter bags, clarification and filtration in food and beverage processing, etc.

eSUN Product Matrix

eSUN focuses on the development of PLA fibers, non-woven fabrics, and their applications, providing PLA staple fibers, filaments, and various non-woven fabric products. Among them, the company has a significant leading edge in the R&D, production, and application of differentiated PLA fibers, such as bicomponent fibers and three-dimensional (3D) crimped fibers. Fiber and non-woven fabric products can also be customized according to customer needs.
