  • Patent number: 10619283
    Abstract: Washed laundry that has been rinsed still contains bound acidic or basic rinsing liquid. In many cases this must be neutralized. This used to be conducted on the basis of values gained from experience, which generally resulted in only partial neutralization. Herein, sample liquid is taken continuously from the neutralization chamber (18) and, after the fine filtration of same, the pH value of the sample liquid is continuously measured by a pH value measurement device (31). In this manner a pH value control system is possible which ensures an automatic and complete neutralization of the rinse liquid still bound in the laundry after rinsing.

  • Patent number: 10570352
    Abstract: Laundry detergents and their use for cold-water cleaning are disclosed. The detergents comprise a lipase and a mid-chain headgroup surfactant or an alkylene-bridged surfactant. The mid-chain headgroup surfactants have a C14-C30 alkyl chain and a polar group bonded to a central zone carbon of the C14-C30 alkyl chain. The alkylene-bridged surfactants comprise a C12-C18 alkyl chain, a polar group, and a C1-C2 alkylene group bonded to the polar group and a central zone carbon of the C12-C18 alkyl chain. Surprisingly, when combined with lipases, detergents formulated with the mid-chain headgroup or alkylene-bridged surfactants effectively liquefy greasy soils at low temperature and provide outstanding cold-water performance in removing greasy stains such as bacon grease, butter, cooked beef fat, or beef tallow from soiled articles.

  • Patent number: 10309048
    Abstract: Repeatable and reliable chemical treatment for loose fibers is achieved by spraying or immersing loose fibers in a chemical treatment bath, and continuously moving the soaked fibers through a continuous centrifuge. The continuous centrifuge controls the wet pickup of the chemical formulation on the fibers and assures a substantially even chemical distribution on the centrifuged fibers. The centrifuged fibers may be dried to fix the chemicals in the chemical formulation to the fibers and/or to remove water from the chemical formulation. Recycling of the chemical formulation from the continuous centrifuge allows for the process to be performed more economically and in a more environmentally friendly fashion.
