Abstract

Strong fabrics are provided that can be used for items that can be moved or gathered while maintaining their integrity. The added strength of the fabric and the performance of the fabric make these fabrics and these items more effective in responding to oil spills. These fabrics and items will remove oil sheen from the surface of water and can absorb more than their dry weight in oil from water. Non-linting socks (e.g., sediment socks or absorbent socks) are also provided.

Claims

exact text as granted — not AI-modified
What is claimed is:

         13 . The article according to  claim 1 , wherein the fabric is dyed. 
     
     
         14 . The article according to  claim 1 , wherein the fabric is oleophilic and hydrophilic. 
     
     
         15 . The article according to  claim 1 , wherein the article is a sweep, a mop comprising strips of the fabric, a pom pom weighing at least 0.05 pounds and comprising strips of the fabric, or a snare comprising strips of the fabric. 
     
     
         16 . The article according to  claim 15 , wherein the fabric is capable of absorbing at least 3 times its dry weight in crude oil,
 wherein the fabric passes the criteria for SW-846, Third Edition, and   wherein the fabric has a thickness of at least 2 mil.   
     
     
         17 . The article according to  claim 1 , further comprising a plurality of pom poms attached to each other, each pom pom comprising strips of the fabric. 
     
     
         18 . The article according to  claim 1 , comprising at least two layers of the fabric, wherein at least one of the layers of the fabric has a basis weight of at least 0.25 osy. 
     
     
         19 . The article according to  claim 18 , wherein the fabric is capable of absorbing at least 7.8 times its dry weight in oil that has a viscosity of 320 centiStokes,
 wherein the fabric passes the criteria for SW-846, Third Edition, and   wherein the fabric has a machine direction grab tensile strength of at least 6.2 lb f  as measured by ASTM D5034.
