'ille installt invention is t:hus particularly a~vantagcous ror retarding the disco]oration of blue and green polyurethal-e foams in the prcset-ce of halide ion-containing anti-microbial agents but can also be used to retard the discoloration of other polyurethane foams including unpigmented white polyurethane foams in the presence of said anti-microbial agents. The instant invention has been found to be particularly advantageous for retarding the discoloration of polyurethane foams in the presence of chloride or bromide ion-containing anti-microbial agents, and particularly chloride ion-containing anti-microbial agents. Since the fabric softener may be a quaternary ammonlum compound in the halide form the presence of halide ions i~ the quaternary ammonium compounds would be expected to have a similar effect on the foam. Therefore if such a quaternary ammonium compound is used together with a halide ion-containing anti-microbial agent such as a chloride or bromide ion-containing anti-microbial agent it may be necessary to increase the amount of zinc sulfate, sorbitol or dextrose beyond that range which is useful when the only halide ion-containing source is the anti-microbial agent.
l~ile the halide ion-containing anti-microbial agent may be a chloride, bromide or iodide ion-containing anti-microbial agent, particularly useful anti-microbial agents according to the present invention are the chloride and bromide ion-containing anti-microbial agents and in particular, chloride ion-containing anti-microbial agents have been found to be particularly suitable according to the present invention.
I~lile the polyurethane foam substrate is preferably a ~le~ible open-celled polyurethane foam, in ~.~hich case the im-pl-egllation rcsults in entrapping or entraining the active system within the cellular structure of the foam, a substantially 3~;~
closed-cell polyu~--Lllalle foam could also bc ~ls~d ~ 17 ~hc ac~ive system bcing coated onto one or botl~ of the surfaces of the foam.
In ad(litioll to the ~abric so~t:ening and/or allti-static a~ent, the active system would include an anti-m;crobially effc-ctive ar.~ount of a halide ion-containing anti-microbial agent and an anti-dis-coloration effective amount of zinc sulfate, sorbitol or dextrose Tne instant invention has been found to be particularly useful when flexible open-celled polyurethane foam having a water absorbant capacity of about 15-30, preferably 15-20, times its weight in water is used as the substrate and the active system is entrapped or entrained within the cellular structore of the foam.
~ nile any suitable fabric softening and/or anti-static agent may be incorporated into or onto the polyurethane foam substrate, particularly useful agents include a mixture c~mprisin ~0-99% by weight of a cationic fabric softener and 1-50% by ~eight of a non-ionic surfactant selected from the group consisting of polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol esters and polyoxypropylene fatty acid esters.
According to a further e~bodiment of the present inven-tion, the cationic fabric softener is present in ~n amount of 50-90%, preferably 65-75%, of the ,abric softening mixture. The amount of non-ionic surfactant must be sufficient to lower the melting point of the cationic/non-ionic fabric softener mixture to within the temperature range of an automatic dryer during the drying cycle. The non-ionic surfactant is present in an amount of 10-50%, preferably 25-35%, of the fabric softening mixture. It may also be necessary to depart somewhat from the above ranges of cationic to non-ionic agents, depending on the particular nature of the cationic fabric softener, the non-ionic surfactant, the ~llickness of the foam substrate bcing used, the nature of tlle anti-micl-obial agent and the specific anti-discol-¦l oration agent used. One prelerred weig;lt ratio of cationic ¦¦ fabric sof~ener to non-ionic surfactant is fl-om about 1:1 to 9:1.
