FABRIC TREATED WITH DURABLE STAIN REPEL AND STAIN RELEASE FINISH AND METHOD OF INDUSTRIAL LAUNDERING TO MAINTAIN DURABILITY OF FINISH
First Claim
1. A fabric comprising one or more polyesters or one or more polyesters blended with other fibers or combinations of fibers, wherein the fabric is treated with a finish comprising at least one fluorochemical stain repellent agent and at least one fluorochemical stain release agent, wherein the fabric has an oil repellency rating of at least 3 as measured by AATCC Test Method 118-2002 and a stain release rating of at least 3 as measured by AATCC Test Method 130-2000 after at least 5 industrial launderings at about 55°

Abstract
The invention provides a fabric comprising one or more polyesters optionally with other fibers which is treated with a finish comprising at least one fluorochemical stain repellent agent and at least one fluorochemical stain release agent, wherein the fabric maintains oil repellency and stain release capability after at least five industrial launderings at about 55° C. to about 65° C. The invention also provides a method of treating a fabric with a finish to impart oil repellency, water repellency, and stain release which is durable to repeated industrial laundering. The invention further provides textile articles comprising the treated fabric, and a method for industrial laundering of such treated fabric and textile articles.

13. A method for treating a fabric with a finish to impart oil repellency, water repellency, and stain release which is durable to repeated industrial laundering, the method comprising the steps of:
-
a) providing a fabric comprising one or more polyesters or one or more polyesters blended with another fiber or combination of fibers;
b) applying a finish comprising at least one fluorinated polyurethane stain repellent agent and at least one fluorinated substituted urethane stain release agent, wherein the ratio of the percent on weight of fabric of the at least one fluorinated polyurethane to the percent on weight of fabric of the at least one fluorinated substituted urethane is from about 0.2 to about 3.0; and
c) drying the fabric with applied finish from about 160°
C. to about 200°
