Summary on Grant Application Form
Nonwoven fabrics are currently made in a flat form, but for many applications a 3D product has to be constructed from the flat fabric. The flat fabric is packaged and despatched by the fabric producer to a converter who has to unpack the fabric, lay it out, cut the appropriate panels, then sew and/or fuse the panels together to produce the final product. The packaging, freight and labour costs, and the wastage during panel cutting can account for 70% of the production cost. The project aims to develop new methods for forming 3D structures directly from fibres and for consolidating 3D structures to the required textile properties. These new methods will enable the building of an integrated process for the production of 3D nonwoven products directly from fibres. This will be a major technological advance on current technology and bring significant efficiency improvements for the industry.The fundamental issues that need to be investigated include the fibre flow dynamics over 3D structures, the monitoring and control of fibre flow, the forming of 3D nonwoven shell structures directly from fibres, the monitoring and control of the fibre distribution within 3D shell structures, the consolidation in 3D form of shell structures to provide the required end-use properties.
