Definitions

• composition which provides care to the treated fabrics, in particular color protection, especially after multiple wash cycles.
• Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundering. These dislodged fibers may form lint, fuzz or "pills" which are visible on the surface of fabrics and diminish the appearance of newness of the fabric. Further, repeated laundering of fabrics and textiles, especially with bleach-containing laundry products, can remove dye from fabrics and textiles and impart a faded, worn out appearance as a result of diminished color intensity, and in many cases, as a result of changes in hues or shades of color.
• Solutions may be found for use in the industrial treatments. However, these solutions are not usually transposable to domestic treatments. Indeed, in industrial processes a strict control over parameters such as pH, electrolyte concentration, water hardness, temperature, etc.. is possible whereas in a domestic washing machine, such a high level of control is not possible.

• a ⁇ 20 lb. net cylinder of ethylene oxide (ARC) is set up to deliver ethylene oxide as a liquid by a pump to the autoclave with the cylinder placed on a scale so that the weight change of the cylinder could be monitored.
• a 750 g portion of polyethyleneimine (PEI) (having a listed average molecular weight of 1200 equating to about 0.625 moles of polymer and 17.4 moles of nitrogen functions) is added to the autoclave.
• the autoclave is then sealed and purged of air (by applying vacuum to minus 28'' Hg followed by pressurization with nitrogen to 250 psia, then venting to atmospheric pressure).
• the autoclave contents are heated to 130 °C while applying vacuum.
• the autoclave is charged with nitrogen to about 250 psia while cooling the autoclave to about 105 °C.
• Ethylene oxide is then added to the autoclave incrementally over time while closely monitoring the autoclave pressure, temperature, and ethylene oxide flow rate.
• the ethylene oxide pump is turned off and cooling is applied to limit any temperature increase resulting from any reaction exotherm.
• the temperature is maintained between 100 and 110 °C while the total pressure is allowed to gradually increase during the course of the reaction.
• Step B)- The reaction mixture is then deodorized by passing about 100 cu. ft. of inert gas (argon or nitrogen) through a gas dispersion frit and through the reaction mixture while agitating and heating the mixture to 130 °C.
• inert gas argon or nitrogen
• the final reaction product is cooled slightly and collected in glass containers purged with nitrogen. In other preparations the neutralization and deodorization is accomplished in the reactor before discharging the product.
• Step A If a PEI 1200 E 7 is desired, the following step of catalyst addition will be included between Step A and B.
• Vacuum is continuously applied while the autoclave is cooled to about 50 °C while introducing 376 g of a 25% sodium methoxide in methanol solution (1.74 moles, to achieve a 10% catalyst loading based upon PEI nitrogen functions).
• the methoxide solution is sucked into the autoclave under vacuum and then the autoclave temperature controller setpoint is increased to 130 °C.
• a device is used to monitor the power consumed by the agitator.
• the agitator power is monitored along with the temperature and pressure. Agitator power and temperature values gradually increase as methanol is removed from the autoclave and the viscosity of the mixture increases and stabilizes in about 1 hour indicating that most of the methanol has been removed.
• the mixture is further heated and agitated under vacuum for an additional 30 minutes. Vacuum is removed and the autoclave is cooled to 105 °C while it is being charged with nitrogen to 250 psia and then vented to ambient pressure. The autoclave is charged to 200 psia with nitrogen. Ethylene oxide is again added to the autoclave incrementally as before while closely monitoring the autoclave pressure, temperature, and ethylene oxide flow rate while maintaining the temperature between 100 and 110 °C and limiting any temperature increases due to reaction exotherm. After the addition of 4500 g of ethylene oxide (resulting in a total of 7 moles of ethylene oxide per mole of PEI nitrogen function) is achieved over several hours, the temperature is increased to 110 °C and the mixture stirred for an additional hour.
• reaction mixture is then collected in nitrogen purged containers and eventually transferred into a 22 L three neck round bottomed flask equipped with heating and agitation.
• the strong alkali catalyst is neutralized by adding 167 g methanesulfonic acid (1.74 moles).
• PEI 1200 E2, PEI 1200 E4, PEI 1200 E15 and PEI 1200 E20 can be prepared by the above method by adjusting the reaction time and the relative amount of ethylene oxide used in the reaction.
