Abstract

A method for reducing time needed for drying fabric comprising laundering the fabric at least 3 times with a composition comprising a linear polyether having a weight average molecular weight less than 5000 that is terminated with —N—(—CH 2 —CH(OH)—CH 2 —Cl) 2 , wherein the linear polyether is deposited on the fabric and reduces the time needed for drying.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for reducing time needed for drying fabric comprising laundering the fabric at least 3 times with a composition comprising a linear polyether having a weight average molecular weight less than 5000 that is terminated with —N—(—CH 2 —CH(OH)—CH 2 —Cl) 2 , wherein the linear polyether is deposited on the fabric and reduces the time needed for drying. 
     
     
         2 . The method of  claim 1 , wherein the molecular weight is less than 4000. 
     
     
         3 . The method of  claim 1 , wherein the molecular weight is less than 2000. 
     
     
         4 . The method of  claim 1 , wherein the fabric is laundered at least 5 times. 
     
     
         5 . The method of  claim 1 , wherein the composition is an aqueous composition. 
     
     
         6 . The method of  claim 1 , wherein the composition is added during a rinse cycle during laundering. 
     
     
         7 . The method of  claim 1 , wherein the laundering comprises washing the fabric and rinsing the fabric. 
     
     
         8 . The method of  claim 1  further comprising drying the fabric. 
     
     
         9 . The method of  claim 8 , wherein the drying is line drying. 
     
     
         10 . The method of  claim 8 , wherein the drying is dryer drying. 
     
     
         11 . The method of  claim 1 , wherein the polyether is present in the composition in an amount of 0.08 to 0.4% by weight of the composition. 
     
     
         12 . The method of  claim 1 , wherein the composition further comprises a fabric softener. 
     
     
         13 . The method of  claim 12 , wherein the fabric softener is present in an amount for a delivered AI of 2.8 to 8 grams per load. 
     
     
         14 . The method of  claim 1 , wherein the composition further comprises a surfactant. 
     
     
         15 . The method of  claim 1 , wherein the method reduces the time needed for drying by at least 5% as compared to a time for drying without laundering with the linear polyether.
