Stretching nonwovens could lead to failure of the product regarding specific end-applications. For example, the stretch applied on nonwovens could increase the air permeability while its filtration efficiency is compromised.
However, stretch is necessary for many biomedical applications. Researchers have created a nonwovens composite that is stretchable, breathable, and absorbent, reportedly superior to materials currently used to fabricate face masks, bandages, and similar medical products.
The University of Georgia researchers developed the material led Gajanan Bhat, head of the Department of Textiles, Merchandising, and Interiors in the College of Family and Consumer Services.
The tests showed that the composite fabrics had improved water absorbency compared to the original nonwovens while maintaining good breathability. The water absorption of the composites was three to 10 times higher compared with the cotton-free fabric.
The composite materials also maintained the ability of nonwovens to recover from being stretched, allowing them to accommodate spontaneous movements without losing their shape.
According to a report by Acumen Research and Consulting cited by Hsiung, the market for nonwoven fabrics is expected to reach a value of billion in 2027.
Found in diapers, feminine hygiene products, and air and water filters, nonwovens are water-resistant, elastic, and breathable, and their ability to filter air makes them ideal for medical uses.
