Abstract:
The invention provides durable nonwoven fabrics comprising staple fibers. Methods of preparing durable nonwoven fabrics based on staple fibers are also provided. The methods can include the steps of at least one of needle punching and hydroentangling. The durable nonwoven fabric can be subjected to additional bonding techniques, such as resin bonding and/or thermal bonding. The durable nonwoven fabrics of the invention provide improved durability over conventional nonwoven fabrics. Further advantages of the inventive nonwoven fabrics include maintaining the smooth surface qualities of the fabric and desirable feel of the fabric even with the enhanced durability. The inventive nonwoven fabrics can also be subjected to additional post-processing techniques that conventional nonwoven fabrics would otherwise be unable to withstand. Further, inks and/or dyes can more readily become adhered to the smooth nature of the surfaces of the inventive durable nonwoven fabrics.
