Definitions

  • the present invention is concerned with an article useful for conditioning clothes in a laundry dryer during the drying cycle which article has a pattern thereon which is substantially removed from the article during the course of the drying cycle thereby indicating to the user of the article that the conditioning agent, which the article contained, has been substantially used up during the course of the drying cycle.
  • Such articles comprise a fibrous, woven or nonwoven flexible substrate coated or impregnated with a suitable fabric conditioning agent or a flexible polyurethane foam substrate impregnated with a suitable fabric conditioning agent which will transfer from the substrate to the clothes to be conditioned during the drying cycle in an automatic laundry dryer. Frequently the user of such an article will attempt to reuse the article on a subsequent bundle of clothes and will be disappointed that the conditioning achieved from the first use is not repeated for the second.
  • GB-A-2007096 relates to the use of a dye to provide visual evidence of the levels of various impregnated compositions present in cloth or other substrates, including polyurethanes.
  • the dye used an anionic dye, preferentially bonds to the impregnated cationic composition, and hence as the composition leaches from the substrate the dye, bonded to it, is carried onto any article being wiped.
  • the present invention provides a decorative pattern on the substrate which is visible to the user at the time the substrate is initially placed in a laundry dryer with the clothes to be conditioned and which pattern substantially disappears from the substrate during the course of the drying cycle.
  • the disappearance of the pattern is intended to indicate to the user that the conditioning agent has been substantially used up and that the substrate therefore does not contain a sufficient amount of conditioning agent to render the article useful a second or subsequent time.
  • an article useful for conditioning clothes in a laundry dryer during the drying cycle which comprises a flexible polyurethane foam substrate impregnated with an effective amount of a conditioning agent characterised by having on at least one surface of the substrate a pattern formed by an ink which adheres to the surface, is stable to the conditioning agent and is stable during the impregnation of the substrate with the conditioning agent, and which pattern substantially disappears from the substrate during this drying cycle.
  • the conditioning agent comprises a fabric softening agent, an antistatic agent, a fabric softening and antistatic agent, a bacteriostatic or a fungicide.
  • the ink used to print the pattern on the substrate preferably comprises a titanium dioxide (Ti0 2 ) water-based ink containing a suitable binder.
  • the loading of ink, measured as dried ink, is preferably from 0.05 to 60 gm- 2 within the patterned area.
  • the conditioning agent is a fabric softening and antistatic agent one suitable class are cationic quaternary ammonium salts or a cationic quaternary ammonium salt in combination with a suitable nonionic surfactant.
  • Any quaternary ammonium salt or combination of quaternary ammonium salt and/or suitable nonionic surfactant which salt, mixture of salts or mixture is known in the art to exhibit fabric softening and antistatic effect and which is compatible for impregnation into a flexible polyurethane foam substrate may be used.
  • Particularly useful cationic quaternary ammonium salts are:
  • Particularly suitable softening nonionics include:
  • nonionics which function as the main or auxiliary softening agents in the present invention
  • nonionics which function as the main or auxiliary softening agents in the present invention
  • melting point depressants and transfer facilitators to the previously mentioned softening compounds (quaternary ammonium salts, anionic and nonionic).
  • quaternary ammonium salts, anionic and nonionic particularly suitable classes of these compounds include the following:
  • the conditioning agent is a quaternary ammonium salt it will have at least one of the properties of softening fabrics and conveying antistatic properties on to fabrics.
  • the present invention also includes a method of conditioning clothes in a laundry dryer during the drying cycle, which method comprises placing in the dryer the article according to the invention together with the clothes to be conditioned.
  • a further aspect of the present invention comprises a method for producing the article of the invention which comprises imprinting a desired pattern on a flexible polyurethane foam substrate either prior to impregnation of the polyurethane foam substrate with the conditioning agent or subsequent to the impregnation.
  • the ink used to imprint the pattern must be one which adheres to the substrate, is stable to the conditioning agent and if the pattern is applied prior to the impregnation step, the ink must be stable during the impregnation step and the ink must be such that the pattern substantially disappears from the substrate during the drying cycle of a laundry dryer.
  • the fabric conditioning agent with which the polyurethane foam substrate is impregnated may comprise a fabric softening agent, an antistatic agent, a fabric softening and antistatic agent, a bacteriostatic agent or a fungicide.
  • An ink which meets the above criteria is suitably a titanium dioxide water-based ink containing a suitable binder has been found to be particularly useful.
  • the loading of ink measured as dried ink within the patterned area is preferably from 0.05 to 60 gm- 2 of finished product.
  • the conditioning agent is a fabric softening agent and antistatic agent
  • it is preferably a quaternary ammonium salt, a mixture of such salts or a quaternary ammonium salt in combination with a suitable nonionic surfactant.
  • the fabric conditioning agent with which the substrate is impregnated is a quaternary ammonium salt or mixture of such salts, said compounds will have at least one of the properties of softening fabrics and conveying antistatic properties thereto.
  • the flexible polyurethane foam substrate which is preferred for use according to the present invention preferably has a thickness of approximately 0.22 cm and a density of approximately 24 Kg m- 3 . It is preferably an open-celled polyurethane foam and preferably the pore density is about 11 pores per cm 2 . If desired, the substrate may be coloured to provide a contrast to the ink which is used to form the pattern.
  • ink system which meets the above set forth criteria may be used, one particularly acceptable ink system is Aqualox II (registered Trade Mark), white, which is an ink system of Inmont Corporation.
  • This ink consists of 35% Ti0 2 in a water-base with an acrylic binder.
  • Many inks contain binders or pigments which are readily dissolved into the active system of the substrate of dryer-added fabric softeners in conditioning agents and thus react with this substrate. This would result in problems during the impregnation of the flexible polyurethane foam substrate with the conditioning agent and would also be likely to cause staining of the clothes during the conditioning step in the dryer.
  • the pattern substantially disappears from the substrate during the course of the drying cycle, the unique partial solvation of the binder by the active system both permits the transfer of conditioning agent and inhibits staining of the clothes.
  • the desired pattern may be imprinted under the flexible substrate by using any standard flexographic printing press.
  • the flexographic printing press utilises a rotary flexible rubber plate in conjunction with a rapid drying ink. While the preferred loading of ink, measured as dry ink, within the patterned area as has been described above as being within the range of 0.05 to 60 gm- 2 , the preferred loading range is in the range of 0.05 to 4.2 g m - 2 .
  • Aqualox 11 (registered Trade Mark), white, a Ti0 2 water-based ink available commercially from Inmont Corp. Lodi, N.J., U.S.A. was used to print a roll of polyurethane foam.
  • the open-celled polyurethane foam had a thickness of 0.22 cm, a density of 24 Kg m- 3 and a pore density of 11 pores cm- 2 .
  • the average dry ink loading onto the foam was 3.2 gm- 2 within the printed areas, or approximately 0.8 gm- 2 over the total surface of the foam.
  • the printed foam was then impregnated with a 5:3 mixture of dimethyl di(hydrogenated- tallow)ammonium methylsulphate polyethoxylated glycol ester in a liquid state at 82°C.
  • the impregnation process is accomplished via a pair of compression rollers neither of which showed any visible evidence of ink solids either during or after the run.
  • the finished printed and impregnated foam was then cut into 7.6x17.8 cm sheets and evaluated in a standard residential clothes dryer. After a normal 50 minute drying cycle the pattern had substantially disappeared leaving no trace of any visible residue on the dark synthetic item used in the testing bundle.
