METHODS FOR MAKING THREE-DIMENSIONAL WEBS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18414636 titled 'METHODS FOR MAKING THREE-DIMENSIONAL WEBS
The abstract describes a method of making a three-dimensional web by spinning continuous filaments, moving them along a travel path, and collecting them on a rotating collection surface with cavities and land areas.
- Continuous filaments are spun from a spinneret.
- Filaments are moved along a travel path towards a rotating collection surface.
- The collection surface has cavities and land areas.
- Fluid pressure is applied to the collection surface to collect the filaments.
- An intermediate three-dimensional web is created with regions formed in the cavities and on the land areas.
- The intermediate web is bonded to form a final three-dimensional web.
Potential Applications: - Manufacturing of three-dimensional webs for filtration, insulation, or reinforcement purposes.
Problems Solved: - Efficient production of three-dimensional webs with varying properties in different regions.
Benefits: - Customizable three-dimensional webs with distinct properties in specific areas.
Commercial Applications: - Filtration systems, insulation materials, composite materials in construction or automotive industries.
Questions about the technology: 1. How does the method of collecting filaments on the rotating collection surface improve the production of three-dimensional webs? 2. What specific properties can be achieved by bonding the intermediate web to form the final three-dimensional web?
Original Abstract Submitted
A method of making a three-dimensional web is provided. The method comprises spinning continuous filaments from a spinneret, moving the spun continuous filaments along a travel path having an end, and rotating a collection surface at or proximate to the end of the travel path. The collection surface comprises cavities and land areas. The land areas are tangentially planar with an outer surface of the collection surface. The cavities are recessed with respect to the outer surface of the collection surface. The method comprises applying a fluid pressure to the collection surface and collecting the filaments on the collection surface to create an intermediate three-dimensional web having first regions formed in the cavities and second regions formed on the land areas. The first and second regions differ in at least one intensive property. The method comprises bonding the intermediate web using a bonding operation to form a final three-dimensional web.
