| titleOfInvention | Durable, antistatic, soil release agent and application thereof |
| abstract | ABSTRACT OF THE DISCLOSURE Durable, antistatic soil release agent which is resistant to yellowing on the substrate treated therewith and which is of the the formula wherein X is an aminoplast resin moiety having amino nitrogen atoms and 4 to 6 methylene groups, each of which methylene groups is attached to an amino nitrogen atom; Y1 is O(C2H4O)5-20R1 wherein R1 is C1-5 alkyl; Y2 is O(C2H4O)5-88R2 wherein R2 is C6-20 alkyl; Y3 is wherein R3 is C4-20 alkyl, C4-20 Y benzyl, R4 is C1-4 alkyl, A is an organic or inorganic anion, each of m and n is at least 1 and the sum of m and n is ? to 100; each of a and b is 0 to 2 and the sum of a and b is 0 to 2; c is 1 to 2; the sum of a, b and c is 1 to 4; said agent having a calculated hydrophile-lipophile balance (HLB) of 14.5 to 18.0, a 20 weight % aqueous solution viscosity, as measured at 20°C on a Brookfield viscometer, of 250 to 16,000 cps (0.250 to 16.000 pascal seconds), an electrical resistivity (Keithley Log R) on polyester fabric, at 20 ? 2% relative humidity and 23 ? 1°C, of no greater than 13.00 initially and no greater than 14.25 after 10 washes, and a soil release rating on polyester fabric of at least 3 initially; process for durably applying said agent to a substrate, which process comprises the steps: (a) diluting the agent with a normally liquid medium to achieve the desired application liquid viscosity, (b) adding sufficient salt or a mono , di-or trivalent metal or of an ammonium cation to achieve a cloud point (measured as described herein), of the diluted agent of step (a), or less than 100°C buy greater than 25°C, or adding sufficient polyacidic compound having a second dissociation constant of greater than 1 x 10-8 to achieve a pH, of the diluted agent of step (a), of 3.0 to 6.0, or adding both said salt and said polyacidic compound to achieve said cloud point and pH, (c) applying the diluted agent of step (b) to the substrate to be treated so as to achieve the desired level of agent on the substrate, (d) drying and curing the agent on the substrate, and (e) recovering substrate which has been durably treated with the agent; and Substrate durably treated with the agent. |
