Softer than PLA nonwovens! This bio-based materials supplier develops new products
Bio-based materials supplier NatureWorks has developed a softer, stronger biopolymer for hygiene applications. Combined with hydrophilic surface treatment technology, Ingeo 6500D for nonwovens also features improved fluid management.
"Based on our expertise in bio-based nonwovens, we have developed a product that, according to our rigorous testing, can increase the softness of spunbond nonwovens by 40%, which is softer than ordinary PLA nonwovens 40% higher speed,” said Robert Green, vice president of performance polymers at NatureWorks. “The tensile strength of the new Ingeo solution provides converters with improved handling and efficient production of low basis weight fabrics on the latest generation of spunbond equipment. We look forward to working with the supply chain as we continue to develop this new Ingeo solutions for nonwovens applications including diapers and wipes.”
When the material is combined with a custom topical treatment developed in collaboration with fiber lubricant manufacturer Goulston Technologies, the result is lighter, thinner absorbent hygiene products that improve fluid management and breathability for improved skin health, NatureWorks said.
According to reports, Ingeo's inherent hydrophilicity results in nonwovens that require less surface treatment and are more durable than polypropylene. There were also significant improvements in immersion surface tension results and multiple impact performance, the company added.
During the manufacturing process alone, NatureWorks' Ingeo biopolymer has a 62% smaller carbon footprint than polypropylene. Ingeo materials are based on long chains of sugar molecules that form when trapping plants and sequestering carbon dioxide. This sugar is fermented to produce lactic acid, which becomes the cornerstone of a range of high-performance materials.
