    摘要: Methods for reducing the surface pilling tendency and improving abrasion resistance of a pillable fabric are disclosed. The methods include providing a pillable fabric including fibrils extending from the surfaces thereof, supporting the fabric, and exposing the fabric to a hydroentanglement process that imparts an energy in the range of at least about 4000 to 5000 KJoules/Kg of fabric using pressures of 200 bars or greater. The presence of fibrils on the fabric surface are reduced to an amount wherein the pilling production on the fabric is less than about 20% after 5,000 cycles of abrasion on a Martindale device according to ASTM D4970 testing standard and the fabric remaining mass is at least about 80% to 90% after 50,000 cycles of abrasion on a Martindale device according to ASTM D4966 testing standard.

    摘要: 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.

    摘要: A composite nozzle strip for hydroentangling of a fibrous mass is provided to lower nozzle erosion potential and increase operational efficiency. The composite nozzle strip comprises a substrate comprising a material of a first hardness having at least one aperture and at least one orifice element comprising a material of a second hardness greater than the first hardness and further defining an aperture of a second diameter less than the first diameter. The at least one orifice element is affixed to the substrate so that the aperture in the orifice element is aligned with the at least one aperture in the substrate for creation of a constricted water jet when subjected to pressurized water.

    摘要: The subject matter disclosed herein relates generally to the production of a predetermined ratio of multicomponent fibers in combination with mono component fibers or other multicomponent fibers, preferably through a spun bonding process. After extrusion, these fibers can produce a fiber network that is subsequently bonded to produce a nonwoven fabric comprising multiple types of fibers. The multicomponent fibers within the network may be processed to remove one component by dissolution or to split the individual components into separate fibers. As a result, the fabric will be comprised of fibers with a range of diameters (micro- or nano-denier fibers as well as higher denier fibers) such that the fibers will not pack as tightly as in a homogeneous nonwoven fabric produced from one type of mono component or multicomponent fiber. The present invention additionally relates to methods for producing nonwoven fabrics with increased loft, breathability, strength, compressive properties, and filtration efficiency.
