Description: DURABLE FABRIC ENHANCEMENT FIELD OF THE INVENTION The present invention relates to novel compounds which are capable of providing fabπc having one or more reactive sites, inter aha. cellulosic fabπc. with one or more durable fabπc enhancement benefits The benefits of the present mvention are delivered to fabric via reactive backbone, preferably a backbone which compπses one or more s-tnazrne, pyπrmdine, cyclotπphosphazene umts, or mixtures thereof These backbone umts are capable of reacting with reactive units of fibers, for example, the hydroxyl umts of cellulosic fibers, to provide a durable enhancement benefit, inter aha, softness, anti-static BACKGROUND OF THE INVENTION Garments have been compnsed of cotton, wool, and silk fiber since antiquity and cotton contmues to be a fabπc of choice for many reasons uicluding its low maintenance Cotton, a wholly natural fiber, is compnsed of crosslinked cellulose the surface of which compπses an abundance of hydroxyl umts which are chemically reactive In fact, one negative against cotton fabπc is the ability of mateπals which compnse stains to react with the cotton fabnc rather than just become absorbed thereto Cotton fabnc is enhanced by the consumer through the wash when the consumer uses fabnc treatment compositions, most notably, fabric softener compositions which can be delivered via laundry detergent compositions, rinse added compositions, or dryer added compositions Compounds which provide a softness benefit are typically added m the mill by the fabπc or garment manufacturer to make the garment acceptable to consumers at the pomt of purchase However, thses finishes are lost during subsequent laundering andd the benefit is mstead renewably added by the consumer dunng laundering Wool and silk fabnc also compnse reactive moieties, but to a lesser degree Typically, cotton clothmg which is treated with softness or anti-static agents loose their fimsh after the garment has been worn and/or laundered For clothmg worn several times pnor to a softness renewal treatment in the laundry, anti-static or softness benefits are gradually depleted dunng wearing of the garment Fabnc has been modified to provide ''permanent press" benefits The process for providing this benefit reacts crosslink g agents with fabnc. typically cellulosic fabnc, which is laid out m a final shape These permanent press processes are typically undertaken under acidic conditions, conditions which can deplete the fabπc of up to 50% of its inherent strength There is a need m the art for a process which provides fabric softness and/or anti-static benefit under non-acidic conditions There is also a long felt need for a compositions which is capable of being applied at the pomt of manufacture in a process which provides durable fabnc softness and/or antistatic benefits to fabric which compnse one or more reactive moieties There is also a long felt need for compounds which when formulated into compositions and utilized in the above descnbed processes, deliver a durable softness or antistatic benefit to fabnc SUMMARY OF THE INVENTION The present invention meets the aforementioned needs in

mvention compnse one or more compounds which compnse a fabnc-reactive heterocychc backbone to which is attached a moiety which delivers a fabric enhancement benefit to fabnc Depending upon the structure of the backbone, there may be present one or more fabric-reactive umts and one or more fabπc enhancement components The compounds which comprise the durable enhancement fabnc modification

Compounds described herem which when delivered to fabπc havmg reactive sites, provides a durable softness or antistatic benefit These and other objects, features, and advantages will become apparent to those of ordinary skill m the art from a reading of the following detailed descnption and the appended claims All percentages, ratios and proportions herein are by weight, unless otherwise specified All temperatures are in degrees Celsius (° C) unless otherwise specified All documents cited are m relevant part, incorporated herem by reference DETAILED DESCRIPTION OF THE INVENTION The present mvention relates to the surpπsmg discovery that fabnc enhancement benefits can be effectively delivered to fabπc which comprises one or more surface reactive umts. for example, cellulosic matenal, inter aha, cotton, rayon, or mateπal compnsed of non-cellulosic mateπal, inter aha, silk The benefits are delivered thereto by one or more fabnc modifying compounds which are capable of reacting with the reactive umts which comprise fabric, for example, the hydroxyl moieties of cellulose, or m a different embodiment, other reactive umts on the surface of wool or silk The fabnc modifying compounds of the present mvention modify the surface of fabπc in a manner which provides softness benefits to the fabric, benefits which are potentially renewable be the consumer The compounds of the present mvention are applied to fabnc dunng the process of assembling the fibers mto fabric, after the fabπc has been formed, or after an artifact of manufacture has been made from said fabnc The fabnc modifying compounds of the present mvention are delivered from a composition which is an aqueous emulsion of the modifying compound The process of the present mvention relates to the step of applymg the modifying agent comprising composition to fabnc at a point m the manufacturing process For the purposes of the present mvention the term "durable" is defined as "a compound which provides a fabnc benefit, inter aha, softness, is applied to fabnc m a manner wherein said compound is covalently linked to the fabnc and does not become detached for reasons other than mechanical loss" For example, a compound accordmg to the present invention which is applied to cellulosic fabric will not transfer to a second surface due to contact with said second surface Instead the compound which provides the benefit remams associated with the fabric surface In a separate embodiment of the present mvention, which relates to a process for applymg said durable benefits by the consumer, the term "durable" also connotes the fact that if by a mechamcal process. inter aha, wearing of the fabnc, one or more "reactive umts " no longer form a covalent bond with the bulk of the fiber, non-reacted "reactive umts" can be potentially re-activated by the consumer thereby re-bondmg the compound to the fabnc The compounds of the present mvention are applied to fabπc m a manner which is different than "fabric substantive" which relies on the attraction of a matenal for the surface of fabπc For the purposes of the present mvention the term "cellulosic fabric" or "cellulosic matenal" is defined as "fibrous cellulose compnsmg-mateπal denved from native sources, inter aha, cotton, rayon, flax, including the pulp of said sources, inter aha. wood pulp, cellulose comprising derivatives, non-lrmitmg examples of which mclude cellulose acetates, cellulose ethers' "Cellulosic fabric" or "cellulosic mateπal" dependmg upon the context is defined as "the raw matenal, inter aha, fibers, or the finished product, inter aha, an article of clothmg" The term "cellulose fabπc" is used mterchangeably for and is meant to stand equally well for "fabric compπsmg 100% cotton fiber, and mixtures of cotton fiber and synthetic fibers" The durable fabric enhancement compounds of the present mvention which comprise the fabπc modifying systems have a modulated reactivity toward fabric surface reactive sites As set forth heremabove, the compounds of the present mvention react with, for example, the hydroxyl moieties which compnse cellulose and provides a rigid link or framework which holds the fabπc enhancement compounds to the fibers For example, a mono-tnazme compound will have three fabnc reactive sites One site is attached to a fabnc enhancement component (which delivers the durable benefit) leaving two sites available for attachment to cellulosic fabnc Also by the choice of fabnc reactive units the formulator can modulate the relative reactivity of the units toward fabnc In an important embodiment of the present invention which relates to "re-attachmg" the substrates to fabπc by the consumer, m the case wherem an ohgomeπc backbone compnses several "differentiated reactivity R 1 fabnc reactive umts". the most chemically reactive, and therefore, fabπc reactive umt, may initially combme with the reactive umts of fiber and the balance of the "differentiated reactivity R 1 fabπc reactive umts" may remain unreacted Therefore, if the pnmaiy R 1 site of attachment is lost due to mechamcal detachment, a secondary, initially less reactive "fabnc reactive moiety" can be reacted with the fabπc surface at the instigation of the consumer, for example, durmg ironmg, or by the deliberate application of a "linking catalyst" As described herem below, some of the compounds of the present mvention are oligomeπc For the purposes of the present mvention the term "ohgomeπc" is defined "as a umt which compπses more than one fabπc reactive heterocychc backbone residue per molecule" For example, one s-tnazme ring can compnse up to three reactive sites two of which can be mtended to react with cellulosic mateπal A compound compnsing two or more, for example, s-tnazme units linked by an R umt as described herem below, is ohgomenc Fabnc Modifymg Compounds The compositions of the present mvention comprise and the processes of the
