Embodiment

[0045] The following examples demonstrate the invention and its properties. The invention is capable of other and different embodiments, and its several details can be modified in several obvious respects, all without departing from the scope and spirit of the invention. Accordingly, the examples themselves are illustrative only and not limiting.

[0046] The examples are numbered using the fluorochemical finish formulation number (1-6) and fabric designation (A-E). For example, Example 1A refers to Fabric A that has been treated with the fluorochemical finish of Formulation 1.

[0047] In the following examples, six formulated fluorochemical finishes were applied to five polyester / cotton fabric samples. The fluorochemical finish was applied to dry fabric by wet wipe, followed by contact drying at 375°F for 1 minute. The treated fabric samples were then washed according to ISO 15797:2002(E), Table 2 Condition 3 Wash Step using a modified wash temperature of 140°F (60°C). A...

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 DEG C to about 65 DEG 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.

Description

field of invention [0001] The present invention relates to fabrics which have been treated with a fluorochemical finish and which retain the durability of the finish through repeated industrial laundering. The fluorochemical finish imparts stain repellency, water repellency, and stain release to the fabric. The present invention also relates to a method of applying a fluorochemical finish that is resistant to industrial laundering of fabrics. The present invention also relates to textiles comprising treatment with said durable fluorochemical finish. The present invention also relates to a method of industrial laundering of fabrics treated with said fluorochemical finish, or textiles comprising said treated fabric, which maintains the durability of said fluorochemical finish. Background of the invention [0002] Fluorochemical finishes are well known for use as fabric treatments or fabric protectants. This fluorochemical finish is used to keep articles of clothing or other...
