  • Cleaning compositions containing lime-soap dispersant and method of preparation
    Patent number: 5854197
    Abstract: Cleaning compositions containing a lime-soap dispersant and a method of preparing liquid cleaning compositions containing lime-soap dispersants are disclosed. More specifically, cleaning compositions containing lime-soap dispersant polymers derived from maleic acid, maleic anhydride, or salts thereof, copolymerized with a hydrophobic monomer containing from 4 to 20 carbon atoms are disclosed. Cleaning compositions containing a lime-soap dispersant based on maleic acid/diisobutylene polymers are particulary effective in producing stable liquid cleaning compositions with good lime-soap dispersancy properties.

  • Apparatus and method of making a non-woven fabric
    Patent number: 5306453
    Abstract: Apparatus and method for the forming of fiber structures or webs utilizing a rotor having a plurality of blade sets helically arranged about its periphery for detangling and declumping air-entrained fibers which are deposited against a sizing screen, said blades act to push individualized fibers, with the assistance of positive air pressure, through the screen into a free-fall zone for deposit on an underlying forming wire.
