The fabric conditioning compositions may be coated onto substrates, and the fabric conditioning articles thereby obtained used to impart softness and anti-static properties to fabric. The method portion of the invention involves the commingling of damp fabrics with the fabric conditioning compositions in an automatic clothes dryer to impart softness and anti-static properties to the fabric.

  • Publication number: 20030013632
    Abstract: A fabric conditioning article for use in a clothes dryer. The fabric conditioning article having a flexible sheet and a fabric conditioning composition deposited on the sheet. The fabric conditioning composition includes a fabric conditioning agent, perfumed particles and minor components. The perfume particles are a perfume composition incorporated into a porous mineral carrier such as clay and/or zeolite. Optionally, the perfume composition comprises low levels of unstable perfume components. Alternatively, the perfumed particles have a coating material encapsulating at least a portion of the particles. Optionally, the articles are packaged in a container having a moisture barrier to prevent premature release of the perfume therefrom.

  • Patent number: 6379394
    Abstract: A soil-repellent treatment method for articles based on woven cotton, wherein an amphiphilic soil-repellent agent soluble or dispersible in the treatment medium is deposited on the article during one or more washing, rinsing and/or softening or dying steps, is disclosed. Said soil-repellent agent comprises at least one unit with a function (FAd) capable of being absorbed onto the surface of the cotton by electrostatic interaction; and at least one hydrophobic unit (MH) capayble of configuring said agent at the cotton/water interface. A soil-repellent agent comprising at least one unit with a cationic function (MC) capable of being absorbed onto the surface of the cotton, and the counter-ion thereof, as well as at least one hydrophobic unit (MH) containing at least four carbon atom chemically bonded to the unit having said cationic function (MC) via an oligomeric, polymeric or copolymeric vinyl alcohol chain, is also disclosed.

  • Patent number: 6357137
    Abstract: Non-woven fabrics prepared from fibers having two different deniers useful as substrates in the preparation of dryer-activated fabric conditioning articles. By combining lower denier fibers with higher denier fibers, a substrate is produced that has the tensile strength similar to that of the lower denier substrate combined with the thickness and coating capacity similar to that of the higher denier substrate. Articles comprising said substrates contain: (A) at least about 5% fabric conditioning composition comprising fabric conditioning active; and (B) said substrate.
