YARDLEY, James, Thomas 40 Macculloch Avenue, (54) Title: SULFONATED 2-(2'-HYDROXYARYL)-2H-BENZOTRIAZOLES ,f.t F2RIM1A EH-DE C-t -N eS S AND THEIR USE TO IMPROVE STAIN RESISTANCE AND DYE LIGHTFASTNESS (57) Abstract A new class of sulfonated 2-(2'-hydroxyaryl)-2H-benzotriazole compounds and method for using them and other sulfonated hydroxyaryl benzotriazoles on nylon fibers to improve stain resistance and dye lightfastness has been discovered. A process is provided for improving stain resistance of nylon fibers by treatment with sulfonated aromatic-formaldehyde condensate and fluorinated dry soil resist agents.

la SULFONATED 2-(2'-HYDROXYARYL)-2H-BENZOTRIAZOLES AND THEIR USE TO IMPROVE STAIN RESISTANCE AND DYE LIGHTFASTNESS BACKGROUND OF THE INVENTION This invention relates to new sulfated 2-(2'-hydroxyaryl)-2H-benzotriazoles and their use to improve stain resistance and dye lightfastness in nylon fibers.

DESCRIPTION OF THE PRIOR ART The prior art is replete with compositions and processes for improving the stain resistance of polyamide (nylon) fibers. The advantages of stain resistance is apparent for many of the uses of nylon, especially when 0 used in carpets. U.S. Patents 3,663,157 and 3,519,669 s ee* disclose certain formaldehyde condensation products S useful as stain resists. The use of fluorine containing S* agents to impart soil resistance of nylons is well known 20 as illustrated by U.S. Patents 4,414,277; 4,209,610; 4,195,105 and 4,192,754. U.S. Patent 3,844,712 to sO Frickenhaus discloses a method of improving the wet fastness of polyamides dyed with cationic dyes by treatment with the salts of condensation products of S 25 formaldehyde and sulfonated diphenyl ethers. However, Frickenhaus does not disclose or recognize any 0 improvement in stain resistance and especially, ,I f Frickenhaus does not recognize that his condensation SeI *products would increase the stain resistance of a 1* 30 polyamide fiber treated with a dry soil release agent.

The unsulfated precursor 2-(2'-hydroxyaryl)-2Hi benzotriazoles (hereinafter sometimes called hydroxy S* benzotriazole or aryl benzotriazole) are disclosed for use to protect organic substances from light-induced deterioration in U.S. 4,226,763 and U.S. 4,278,589. Use of sulfonated 2-(2'-hydroxyaryl)-2H-benzotriazoles as photostabilizing agents for natural and synthetic fibers is disclosed in a published international application under the Patent Cooperation Treaty (PCT), Publication 4/'Q 40 No. WO 84/02365 and in U.S. 4,668,235.

3 w The invention also provides methods for improving resistance to staining by anionic staining compounds and improving lightfastness of dyes on nylon material which 911030,immdatl28,a:\27974alLres,2 -3comprises treating the nylon material with an effective amount of an aqueous solution of the above described sulfonated benzotriazole at mild temperatures.

The preferred method of treatment is an aftertreatment at a pH of between about 2 and 5. The preferred treatment temperature is between about 30°C and The preferred time to aftertreat the fiber is after dyeing, preferably from about 10 to 30 minutes in duration. The compounds are also useful to improve properties of nylon materials in other forms, such as film.

The terms nylon and pol amide as used herein denote those synthetic long chain polyamides having recurring o amide groups as an integral part of the polymer chain.

6 15 Exemplary of such polyamides are nylon 6, nylon 66, nylon 12, etc.

goes When not otherwise defined, as used in this specification alkyl means a paraffin hydrocarbon radical *e* derived from an alkane by dropping at least one hydrogen atom, such radicals containing from one to about thirty carbon atoms.

Advantageously the compounds of the present invention are used in conjunction with sulfonated aromatic-formaldehyde condensation products having the S* 25 following structure (hereinafter called the "preferred $e.se DPE condensate"): 0*

S

3 0 0 H 5 L Jm ILJ wherein m is 0 to 4, n is 0 to 3 and x is 1 to 5. Most preferred are the compounds wherein m is 0 or 1, n is 0 to 2 and x is 1 to 3, except the nonpreferred species are 911031,mmdaLl28,a:\27974alLres,3 rIJ -4compounds wherein m n 0 or 1 along with x m n i, or wherein m 0, n 1 and x 2. A particularly wellperforming compound is when m 1, n 0 and x 2.

These agents are described more fully in International Publication No. WO 88 02042.

The method of the invention can be advantageously combined with the use of fluorinated dry soil release agents. Although the use of fluorinated dry soil release (DSR) agents have been previously employed to impart stain resistance to polyamide carpet fibers, it has been found in accordance with this invention, that the use of such DSR agent in conjunction with the sulfonated aromatic condensate results in a synergistic effect producing a superior stain resistance than either 15 treatment agent alone. Additionally, the resistance of such fibers to ozone fading is surprisingly improved.

°The term fluorinated dry soil release agent as used herein is intended to denote those agents known and used in the art to impart increased soil resistance to polyamide fibers, particularly, carpet fibers.

Particularly useful in the process of this invention are the fluorinated dry soil release agents of the types disclosed in U.S. Patent Nos. 4,191,754; 4,604,316 and 4,605,587, which are incorporated herein by reference.

25 It is preferred that the fiber first be treated with the a ge* fluorinated dry soil release agent and thereafter with the inventive compounds although that sequence may be reversed.

The use of the compounds of the present invention 4 30 are preferentially concentrated near the surface of e.g., S" fibers of nylon to ensure optimum effective absorption of wave lengths of radiation which cause photo degradation of nylon and dyes in nylon. The anionic portion of these molecules ensures that they will be strongly attracted to nylon under the application conditions. However, the relatively hydrophobic remainder of the molecules will not readily migrate into the bulk of nylon. This unique 911031,immdat 128,a: 27974a]Lres,4 balancing of effects results in optimal near-surface concentration of these light screens. This renders them remarkably effective both as UV light screens and as stain repelling agents.

The inventive compounds useful in accordance with this invention are water soluble and can be applied to nylon in a variety of ways. Typically, the compounds are applied to dyed fiber from either a dilute or concentrated aqueous solution with a concentration range between 0.001 and 75 weight percent. The solution is contacted with the polyamide fiber for 5 seconds to minutes at temperatures ranging from room temperature to about 100 0 C. The pH of this solution should be between 1.0 and 5.0, preferably about 2.0. It has been found 0 15 that when the pH of the solution is at the lower pH values the percent exhaust and stain resist property of the treated fiber is significantly improved. For this reason, it is preferred to employ sulfonated inventive compounds with -S03H groups instead of sulfonate salts.

@0 After treatment, the fiber is water extracted and oven dried at 120*C. The sulfonated condensates useful in this invention can be applied to dry or wet fiber either as a concentrate or dilute solution. The treated fibers will generally contain the inventive compounds in amounts of between 0.05 and 10% OWF (on the weight of fibers) and the treatment bath conditions should be maintained accordingly.

The method for applying the optional fluorinated dry soil release agent (DSR) to polyamide fibers is known in 9 30 the art and is thus not necessary to describe in detail.

In general, the fibers may be contacted with a spin finish containing the DSR agent in a known matter or other suitable procedures may be employed. The amount of DSR on the fibers resulting from the process of this invention should be between 0.05 and 1.0% on weight of fabric (OWF).

911030,immdat.28,a:\27974alLres,5 v jo -6- The treated nylon carpet fibers are tested for stain resistance in the following manner: A treated sample of nylon carpet yarn in circular knit sleeve form is placed on a non-absorbent surface and a small (10 ml) beaker containing 2 ml of staining solution Cherry Kool-Aid™ is inverted on the fabric and slowly agitated in such a manner that the liquid is retained within the beaker and in contact with the fabric until the termination of the test, or absorption of the staining solution by the fabric takes place. After 5 minutes, or other suitable period of time, the beaker and remaining solution are removed and any excess liquid on the fabric is blotted away with absorbent paper towels. The depth of the stained area is then visually assessed by use of a. 15 the AATCC Gray Scale for staining, the AATCC Chromatic Transference Scale, or other suitable comparative method.

3 Cyasorb UV-54 Since these compounds are generally soluble only in organic solvents, the incorporation of such material into *V nylon poses serious problems. Surface application from organic solvents is a hazardous process and may result in a non-uniform coating of poor durability. Addition of these materials during extrusion may result in thermal degradation, may result in an ineffectiveness distribution of material, and may result in loss of material due to volatility under extruder conditions.

It has been proposed to sulfonated hydroxyaryl benzotriazoles to ameliorate some of these deficiencies.

In addition, these fibers demonstrate increased resistance to staining by certain common stains, especially those containing anionic groups.

This example demonstrates that hydroxybenzotriazoles lose photostability in a polyamide environment. It also demonstrates that incorporation of bulky hydrophobic groups near the intramolecular hydrogen bond (especially in the ortho position relative to the hydroxyl group) effectively provides for a high degree of photostability.
