Definitions

• the invention relates to spray-on anti-soil formulations, for all fibers and specifically, to spray-on anti-soil formulations for polyester and olefin fibers, carpets, and fabrics.
• the anti-soil formulations comprise a synergistic blend of an anti-soil component and a stain blocker component.
• Soil repellant fibers, carpets, and fabrics, with improved anti-soil properties, are also disclosed. Also disclosed herein are processes for making soil repellant fibers, carpets, and fabrics.
• carpets are currently treated with topical chemistries for improved stain resistance and/or soil resistance.
• stain blocker e.g. acid dye blocker
• anti-soil with fluorochemicals are traditionally used.
• polyester carpets such as 2GT and 3GT carpets, and polypropylene carpets, either no topical chemistry is applied or only anti-soil is topically applied.
• Polyester and polypropylene carpets typically do not require a stain blocker topical treatment because of inherent stain resistance and lack of amine end groups that function as dye sites.
• Topical application can be in the form of exhaust application (i.e. flex-nip process at high (300 - 400 wt.%) wet pick-up), which is known to be an improvement over spray-on applications at 10-20 wt.% wet pick-up of anti-soil.
• Exhaust applications typically use higher amounts of water and energy to dry and cure the carpet.
• Spray-on fluorochemical products are designed to use less water and energy than exhaust applications, but do not impart satisfactory anti-soil properties. While various processes are in use in the carpet industry for the dyeing and finishing of carpets, some large scale and some small, most of the broad loom carpet made today is dyed and finished on a continuous dye range.
• the carpet is also steamed and dyed first, steamed again, rinsed and extracted; and then a blend of SB and FC is applied together at high wet pick up, after which the carpet and chemicals are exposed once again to steam to fix the treatment, followed by drying.
• a blend of SB and FC is applied together at high wet pick up, after which the carpet and chemicals are exposed once again to steam to fix the treatment, followed by drying.
• anti-soil compositions that can be applied by spray-on applicators are in demand because spray-on processes use less water and energy to dry than exhaust applications.
• current spray-on compositions do not impart satisfactory anti- soil properties at the necessary low wet pick-up during application.
• anti-soil compositions that can be applied via spray-on processes at low wet pick-up.
• Such compositions would be ideal for carpets made from dyed fiber that has no need for further exposure to exhaust processes.

• the invention disclosed herein provides a spray-on anti-soil composition comprising an anti-soil component and a stain blocker component.
• the spray-on anti- soil composition can be used with a variety of fibers, carpets, and fabrics, such as those manufactured with olefin and polyester polymer components. Such composition is counter-intuitive, since certain olefin and polyester fibers, carpets, and fabrics do not require stain blockers because they are inherently stain resistant. Thus, there is a surprising synergistic effect with a composition comprising both an anti-soil component and a stain blocker component.
• the anti-soil component can be either fluorochemical or non-fluorochemical based.

It should be noted that the Delta E will be a function of initial color of the carpet. The above results are with respect to a carpet color in the range from about 58 to about 68 L value. Further, carpets treated with the various aspects of the disclosed anti-soil composition exhibit improved Delta E soil resistance after hot water extraction compared to fluorochemical only treated carpets. When the carpet is darker, or L value is less than this range specified, the soiling delta E will also be less (i.e. it will be harder to see the color change in a carpet that is darker).

• the combination of anti-soil and stain blocker yields a surprisingly synergistic anti-soil composition that is more effective at improving soiling resistance of carpet.
• stain block by itself, does not impart any anti-soil characteristics to fibers.
• stain block typically is not usually required with polyester (e.g. PET and PPT) and olefin (e.g. polypropylene) fibers because these polymers lack amine end groups that function as acid dye sites and are inherently stain resistant.
• the combination of anti-soil and stain block components on olefins and polyesters is synergistic, as surprisingly low levels of application can be effective.
• anti-soil composition can be applied to the fiber, carpet, or fabric via spray-on application instead of exhaust application, while still maintaining superior anti-stain properties.
• polyester and polypropylene rugs treated with the anti-soil compositions disclosed above compared to a standard anti-soil fluorochemical treated rug and as well as rug with no treatment.
• Selection of alternative anti-soil components and stain blocker components, fibers and textiles having different surface chemistries will necessitate minor adjustments to the variables herein described.
• Walk Test A description of the walk test is as follows:
• Walk way selection Select a walk way with a highest traffic volume possible.
• the samples should be located 20 to 30 feet from an outside entrance.
• walk off areas (example: carpet tiles) on both ends of the test extending at least for 6 to 8 feet.
• One set of sample carpets or multiple set of samples can be installed. Measure the initial L, a, b (using a Minolta spectraphotometer) of samples. As the soiling proceeds, take readings of L, a, b, and calculate Delta E. This delta E represents the color change of the sample when compared to the sample of the same carpet prior to soiling. When the Delta E reaches a high value, it will be time to hot water extract (HWE) and measure delta E after cleaning. This process can be repeated to obtain data over multiple cleanings and traffic cycles.
• HWE hot water extract
• Samples 6 and 7 showed a Delta E improvement of 64% to 70%, while Samples 4 and 5 showed a Delta E improvement of only about 50%.
• Delta E results of Samples 6-7 are low enough that they are acceptable commercially. Carpets treated with the disclosed anti- soil compositions respond better to carpet cleaning than traditionally treated carpets and have superior soiling results throughout walk test including after cleaning.
• Daikin TG 2511 was a cationic formulation and DuPont chemistries were anionic formulations. This shows that the process of this invention works well for different types of formulations of fluoro chemical chemistries.
