Definitions

• the lubricant makes ironing of clothes easier by providing excellent lubricity between the iron and the fabric, by conditioning the surface of the iron thus reducing starch buildup and making ironing of non-starched clothes easier, by improving the scorch resistance of the starch, and by imparting a softer hand to the starche'd clothes.
• This lubricant also alleviates the problem of spray dilation.
• the modern housewife has such things as instant foods, complete frozen meals, automatic cooking implements, electric can openers, garbage disposals, dishwashers, home permanents, hair driers, wigs, false eyelashes (etc.), automatic clothes washers and driers, wrinkle resistant clothes, wash and wear clothes, and permanent press (would you believe almost permanent?) clothes.
• Patent 3,294,725 the disclosure of which is hereby incorporated by reference, is employed as a lubricant in a starch composition that the concentration can be reduced to a level where the heretofore known polydimethylsiloxane lubricants are virtually useless.
• Aerosol starches were prepared as follows:
• a concentrate was prepared which consisted essentially of 95.43% or 95.63% water, 0.2% or 0.4% of emulsions containing 35% of various polydimethylsiloxane fluids having viscosities of about 100,000 c.p.s., 4% starch, 0.1% sodium benzoate (preservative), 0.03% formalin (bactericide) and 0.04% sodium bicarbonate (buffer).
• This concentrate was prepared by adding the starch to the water with continuous stirring, raising the temperature of the water to boiling, holding the temperature above 90 C. for 15 minutes, and then cooling with continued agitation -to room temperature. Finally, the remaining ingredients were added.
• Fluid A was prepared by the solvent polymerization of dimethylsiloxane cyclics.
• Fluid B was prepared by the emulsion polymerization of dimethylsiloxane cyclics using the process of US. Patent 3,294,725.
• Fluid C was prepared by the emulsion polym erization of a hydroxyl endblocked polydimethylsiloxane using the process of US. Patent 3,294,725. Specifically, fluid C was prepared as follows: 608 g. of deionized water was placed in a 1500 ml. beaker and then 4.7 g.
• Fluids A and B correspond to prior art materials and have been included for purposes of comparison.
• Fluid C represents the instant invention.
• the above prepared aerosol starches were evaluated as follows: The hot iron to be used was cooled by running cold water on the sole-plate until it was cool to the touch. In the center of the sole-plate some Wisk detergent was squirted (a spot about the size of a quarter) and about one-third of a gram of Kaopolite SF placed on top of the detergent.
• Wisk is a commercial heavy duty liquid detergent consisting essentially of about 20-25% inorganic builder salts (complex silicates and phosphates), 10-15% synthetic detergents (dodecylbenzene sulfonate, tallow alcohol sulfate, lauric diethanolamide, alkyl phenol ethylene oxide adduct), 10% solubilizing agents (sodium alkyl naphthalene sulfonate), 02-04% anti-redeposition agent (sodium carboxymethylcellulose) 0.0-0.6% colloidal dispersant (Methocel-methylcellulose), 0.1% optical brightener and the balance water.
• Kaopolite SF is anhydrous aluminum silicate plates used as an abrasive.
• a piece of cheesecloth folded into a 2" by 2" square was wet with water and used to vigorously rub the detergent- .abrasive mixture over the sole-plate of the iron. Rubbing was continued until the cloth began to drag. Then the cloth was wet with more water and rubbing continued until there was some pick-up of metal on the cloth. Then the detergent-abrasive mixture was rinsed off with water and then the water rinsed off with isopropanol. Finally, the sole-plate was briskly wiped dry with a clean piece of cheesecloth. The temperature contnol on the iron was set half Way between the linen and cotton settings'about 425 F.
