AI Technical Summary

Benefits of technology

The present invention provides a composition that can be applied to a substrate to make it stain resistant. The composition includes a mixture of an anionically modified phenol formaldehyde polymer, a naphthalene condensate, a lignin sulfonate, a phenol sulfonate derivative, a (meth)acrylic polymer, and a polyester. The composition can be applied to the substrate using an aqueous solution or dispersion, and can be used to make articles with polyamide groups that are stain resistant. The technical effect of the invention is to provide a stain-resistant substrate that can be easily treated with a composition that includes a mixture of an anionically modified phenol formaldehyde polymer, a naphthalene condensate, a lignin sulfonate, a phenol sulfonate derivative, a (meth)acrylic polymer, and a polyester.

Problems solved by technology

Those skilled in the art recognize that while anionically modified phenol formaldehyde polymers, napthalene condensates, lignin sulfonates and phenol sulfonate derivatives provide stainblocking, their photo instability causes yellowing of the dyed substrate over time.

example 1

[0057] In this example, the substrate, nylon type 6 superba, a fiber, was treated using 1.8%, based on the weight of the substrate (owg), of stainblocker foamed on using 5 g / l of Arrofoam 2273 at 30% wet pickup at a pH of 3.5. The treated substrate was cured by steaming for one minute and then the substrate dried. The effectiveness of the stainblocker was checked using sweetened cherry KOOL-AID at ambient temperature with 20 ml KOOL-AID liquid poured onto the surface of the carpet in a 23 cm diameter ring. The KOOL-AID was allowed to contact the surface of the carpet in a 23 cm diameter ring. The KOOL-AID was allowed to contact the surface of the carpet for one minute and then was cold water rinsed, dried and graded. The coffee stain test consisted of contacting 20 ml of 180 degree coffee placed into a 23 cm ring for one minute onto the surface of the test carpet. The sample was cold water rinsed, dried and rated. In addition to the cherry KOOL-AID test described below, AATCC Method...

example 2

[0062] Conventionally, stain resist programs are run in conjunction with fluoropolymers which show enhanced stainblocking. The following results are based on the same testing procedures from Example #1 and all applications are the same except that fluoropolymer has been added to the foamed on mix at 1% based on the weight of the substrate [0063] Sample 5—Control—No treatment [0064] Sample 6—1% Fluoropolymer blend (38% of 30% fluoropolymer of a 10% fluorine; 8% polyester dispersion; the balance primarily water).

[0065] Sample 7—1% fluoropolymer blend as sample 3 and 1.8% XSB-1 (see Example 1).

TABLE 2SampleKOOL-AIDCoffee / Tea Stain533677799

[0066] To one knowledgeable in the art, the addition of a fluoropolymer enhances stain resist to KOOL-AID and other common stain elements such as coffee and tea. Table 2 demonstrates the effect of these stains on untreated (control), fluoropolymer only treated (6) and fluoropolymer, phenol-formaldehyde, polyester dispersion (7) treated carpet sampl...

example 3

[0067] In this trial, a fluoropolymer consisting of 38% of a 30% of a 10% fluorine fluoropolymer was mixed with 8% polyester dispersion, 4% emulsifier and the balance water, and this product for this trial will be called “MIXBA”—and all references to this consist of the above formulation.

[0068] These trials were completed at a fiber producers laboratory using a modified Kuster Fluidyer for foam application of a liquor at 15% wet pick up. Each of the different fifteen liters of the liquor to be applied was prepared in the following manner. To the 15 liters of water, 5 g / l of Arrofoam 2273 was added, 1.8% based on the weight of the goods or 120 g / l mix of the stain resist (except sample #15) and 1% based on the weight of the goods or 66 g / l mix of fluoropolymer (MIXBA). The pH of the liquor in each case was adjusted to 3.5 using sulfamic acid. All samples were dried at 300 degrees F. for 5 minutes, backed and then tested in the previously described manner. [0069] Sample 8 MIXBA+XSB-1...

Abstract

The invention concerns a stain resist composition comprising: (a) a component selected from the group consisting of (1) a naphthalene condensate, (2) a lignin sulfonate, (3) a phenol sulfonate derivative, a mixture thereof and (4) a (meth)acrylic polymer comprising residues of acrylic or methacrylic acid; and (b) a polyester.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation of, and claims the benefit of, U.S. application Ser. No. 09 / 121,980, filed Jul. 24, 1998, which status is allowed. The application Ser. No. 09 / 121,980 claims priority to U.S. Provisional Application Ser. No. 60 / 078,198, filed Mar. 16, 1998. U.S. application Ser. Nos. 09 / 121,980 and 60 / 078,198 are herein incorporated by this reference in their entireties.FIELD OF THE INVENTION [0002] The present invention relates to methods and compositions for imparting stain resistance to a substrate. Substrates that may be treated with the methods and compositions of the invention preferably include fibers containing free amino groups, including, but not limited to, polyamide fibers. The processes and compositions of the invention provide the substrate with stain resistance and good photo stability, which prevents yellowing. BACKGROUND OF THE INVENTION [0003] Materials and substrates containing free amino groups are ...
