Compostable crosslinked cellulose for diaper inner liners
A sustainable, compostable diaper inner liner made from crosslinked cellulose, offering enhanced mechanical strength, absorption, and breathability. This biobased solution addresses environmental concerns while meeting performance standards.
Overview
Compostable crosslinked cellulose presents an innovative solution for diaper inner liners, combining sustainability with high-performance features. This biobased material is designed to meet the growing demand for eco-friendly products without compromising on quality. By leveraging the properties of oxidized cellulose, this technology enhances mechanical strength and fluid absorption, ensuring a compostable alternative that maintains the softness and breathability essential for disposable diapers.
Technical specifications
Key features:
- Crosslinked cellulose fibers: Enhanced hydrophilicity and structural integrity ensure rapid fluid uptake and robust mechanical performance.
- Controlled blends: Carefully formulated blends of crosslinked cellulose with conventional cellulose fibers optimize cost and performance, balancing absorption with strength.
- Nonwoven fiber webs: Wet-laid nonwoven sheets with basis weights of 15–20 gsm are engineered for improved absorption, softness, and breathability.
- Environmental benefits: Offers a compostable alternative to traditional diaper materials, aligning with environmental and consumer sustainability goals.
Technology readiness level
The technology is at TRL 5, having been validated in a relevant environment. The next steps involve optimizing the nonwoven structure for maximum performance and integrating it with bio-based adhesives for diaper construction. Further support is sought for manufacturing, testing, and essential staffing to advance this technology to higher readiness levels.
