  • Patent number: 4735673
    Abstract: This machine is intended for bonding stretched pieces of elastic band to a moving sheet so that these pieces extend transversely relative to the direction of movement of this sheet.The pieces are transferred from a cutting station to a stretching station by means of a transfer station.The stretching station comprises several pairs of grippers distributed around an axis about which they are driven in rotation. The grippers of one and the same pair are arranged axially opposite one another and are designed to be successively moved away from, and close to, one another so that, during their rotation, they grip the lateral ends of the pieces subsequently stretching the latter by moving axially away from one another. Once stretched, the pieces are bonded to the sheet entrained about a drum at the moment when the grippers pass opposite this sheet.The invention is used for the production of a composite sheet intended for providing diapers.

  • Patent number: 4725455
    Abstract: A particulate built nonionic synthetic organic detergent composition includes a detersive proportion of a nonionic synthetic organic detergent and a building proportion, in combination, of a polyacetal carboxylate builder for the nonionic detergent and a polyphosphate builder for such nonionic detergent. Such compositions are readily made by adding polyacetal carboxylate builder to the formula of a control detergent composition, with corresponding diminutions of other component(s), and have detersive powers superior to such control despite the decrease in detergent and other builders. Preferably, certain nonionic detergents, polyacetal carboxylate builders and polyphosphate, in certain proportions, are employed for better detergency and physical characteristics, e.g., flowability.

  • Patent number: 4721633
    Abstract: A process is described in which a particulate detergent composition which is speckled in appearance is made by spraying an aqueous coloring medium, such as dye solution, containing polyacrylic acid, onto the surface of a moving bed of detergent composition particles containing an alkaline builder, thereby forming a coherent colored surface section or "skin" of detergent composition particles. The coherent section or skin of particles is next broken up and the colored particles are mixed with uncolored particles from the bed to make the speckled detergent composition. Normally, the bed of detergent composition particles is on a moving conveyer belt, which conveyer belt is preferably a weigh-belt, and the amount of coloring medium being sprayed onto the moving bed is automatically regulated by the weight of detergent composition particles on the belt passing under the spray nozzle(s), and the belt speed.

  • Patent number: 4720399
    Abstract: A particulate built nonionic synthetic organic detergent composition includes a detersive proportion of a nonionic synthetic organic detergent and a building proportion, in combination, of a polyacetal carboxylate builder for the nonionic detergent and carbonate and bicarbonate builders for such nonionic detergent. Such compositions are readily made by adding polyacetal carboxylate builder to the formula of a control detergent composition, with corresponding diminutions of other component(s), and have detersive powers superior to such control despite the decrease in proportions present of detergent and other builders. Preferably, certain nonionic detergents, polyacetal carboxylate builders, carbonate and bicarbonate, in certain proportions, are employed to make a product of better detergency and physical characteristics, e.g., flowability.

  • Patent number: 4715969
    Abstract: A fabric softening heavy duty liquid detergent composition of controlled viscosity, which does not thicken excessively on aging, includes certain proportions of sodium linear higher alkylbenzene sulfonate, sodium alkyl polyethoxy sulfate, builder salt (highly preferably a mixture of sodium tripolyphosphate and sodium carbonate), finely divided swelling bentonite, low molecular weight polyacrylate and water. Such product is a stable pourable liquid of desired viscosity, density and pH, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered. The presence of a small percentage of the polyacrylate in the composition prevents the viscosity thereof from increasing on storage to such an extent as would interfere with pourability.

  • Patent number: 4715862
    Abstract: A wash cycle fabric conditioning composition, which makes laundry washed in an automatic washing machine and dried in an automatic laundry dryer resistant to the accumulation of static charges thereon, and which may be in particulate, liquid, or other suitable form, comprises an antistatic N-higher alkyl neoalkanamide or an antistatic N-higher alkenyl neoalkanamide, or a mixture thereof, and a detergent builder, such as a water soluble builder salt or a zeolite, or a mixture thereof, as a carrier, or an aqueous medium containing a nonionic surface active agent. Specifically preferred neoalkanamides of the type described are N-higher alkyl neodecanamides, such as tallowalkyl neodecanamide. In some instances, bentonite may be included in the particulate compositions to soften the fabrics that are washed, and tertiary amines may be formulated into the liquid compositions to increase fabric softening action.

  • Patent number: 4714559
    Abstract: Polyamides of trialkylacetic acids and polyamines are new compounds which are of an oily nature at washing temperatures in the 10.degree. to 90.degree. C. range, are capable of being adsorbed from wash and rinse waters by fibrous material, such as laundry, of synthetic fabrics, e.g., polyesters, which laundry is susceptible to being electrostatically charged, and decrease any electrostatic charge or inhibit accumulation thereof on such materials. Such polyamides, e.g., those of neodecanoic acid and ethylene diamine or hexamethylene diamine, N,N'-ethylene-bis-neodecanoamide and N,N'-hexamethylene-bis-neodecanoamide, respectively, can be incorporated in detergent compositions, in compositions for addition to rinse waters and in compositions for application to laundry in a laundry dryer.
