  • Patent number: 6784151
    Abstract: A multi-step process for making a granular detergent composition. The processing steps include adding to a mixer a first feed stream selected from a first powder, a first liquid, and mixtures thereof, to form a second feed stream. The second feed stream is added to a fluid bed dryer to form the granular detergent composition, and optionally, a third feed stream selected from a second powder, a second liquid, and mixtures thereof can be added to the fluid bed dryer. The granular detergent composition contains at least about 50% by weight of particles having a geometric mean particle diameter of from about 500 microns to about 1500 microns with a geometric standard deviation of from about 1 to about 2. Further, at least a portion of the particles contain a detersive surfactant or a detergent builder.

  • Patent number: 6743761
    Abstract: A one step method for the treatment of a non-finished textile component is provided. The method comprises the combination of a bleaching and de-sizing treatment steps into a single step and comprises treating a non-finished textile component in an aqueous treatment solution of a hydrophobic bleaching system and a de-sizing system. Preferred hydrophobic bleaching systems are combinations of hydrogen peroxide and a hydrophobic bleach activator or a hydrophobic peracid. Preferred bleach activators include the alkanoyloxybenzene sulfonates and in particular noanoyloxybenzene sulfonate. The method provides superior fiber protection and fabric strength benefits versus conventional processing as well as allows significant savings in both energy and time due to the elimination of multiple washing and/or drying stages and lower bleaching temperatures.
