preparation example Construction

[0234] In other preparations, neutralization and deodorization are done in the reactor before the product is discharged.

[0235] PEI 1800E if required 7 , add the following catalyst addition step between steps A and B.

[0236] Vacuum was continuously applied while the autoclave was cooled to about 50°C while 376 g of 25% sodium methoxide in methanol solution (1.74 moles, 10% catalyst loading based on PEI nitrogen functionality) was added. The methoxide solution was pumped into the autoclave under vacuum, then the set point temperature of the autoclave temperature controller was increased to 130°C. Use a device to monitor the power consumed by the stirrer. Monitor the power of the stirrer, as well as the temperature and pressure. As the methanol was removed from the autoclave, the stirrer power and temperature values ​​were gradually increased and the viscosity of the mixture increased and stabilized within about 1 hour, indicating that most of the methanol had been remove...

[0257] 160 g of fabric were treated with composition A. The fabric is then left to dry and goes through an ironing process set on linen. After further washing cycles, it was then observed that fabrics treated in this way showed better dye fixing properties than fabrics that had not undergone the ironing process.

[0258] The same results were obtained with compositions B-H.

Abstract

The present invention relates to a fabric care composition comprising a polyamino-functional polymer and a cellulose reactive dye fixing agent, said composition providing effective care to the color of the treated fabric. Also provided herein is a method for the domestic treatment of a fabric to reduce the amount of dye released from the fabric during wet treatments and comprising the step of contacting the fabrics with a polyamino-functional polymer and a cellulose reactive dye fixing agent as defined herein; and thereafter subjecting the treated fabrics with a heating source in a dry medium.

Description

field of invention [0001] The present invention relates to fabric softening compositions and more particularly to methods and compositions for reducing the amount of dye released from colored fabrics upon subsequent wet processing, such as occurs in laundering operations. Background of the invention [0002] Home treatment of colored fabrics is a well known problem in the art to formulators of laundry compositions. More specifically, the problem of formulating laundry compositions that reduce the amount of dye released from colored fabrics when wet processed presents a particular challenge to formulators. This problem is even more acute now as consumers tend to favor more pigmented fabrics. [0003] Various solutions to this problem have been proposed in the prior art, for example by treating the fabric with a dye scavenger during laundering, as exemplified in EP0341205, EP0033815 or by treating the fabric with a polyethylene-based substance, as in WO9...
