Abstract (en)

[origin: US2005125908A1] 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.
