Definitions

  • Sheet substrates for use in a laundry dryer are disclosed in Canadian 1,005,204.
  • U.S. 3,956,556 and 4,007,300 relate to perforated sheets for fabric conditioning in a clothes dryer.
  • U.S. 4,692,277 discloses the use of 1,2-octanediol in liquid cleaners. See also U.S.
  • the coversheet substantially envelops the substrate.
  • the tackiness agent is on the internal surface of the coversheet.
  • the cleaning/refreshment composition comprises up to about 2%, by weight, of a nonionic surfactant.
  • the cleaning article made therefrom rarely refolds during use.
  • the cleaning article carries the cleaning/refreshing solution into the bag, and cleaning and refreshing of the fabrics occurs only after the solution evaporates from the sheet.
  • Refolding of the cleaning article diminishes the exposed surface area of the article, which in turn diminishes the rate of evaporation of the solution, resulting in less cleaning/refreshing vapors in the bag.
  • the textured cleaning articles of this invention are substantially more efficient at delivering the cleaning/refreshing solution to the fabrics being cleaned and refreshed.
  • Figure 6 is a perspective of an un-notched vapor-venting bag containing a loose cleaning refreshment article of the present invention.
  • tackiness agent By “tackiness agent”, “tackifying agent” or “tackifier” herein is meant a material which is used to impart adhesive properties to otherwise substantially non-adhesive materials, i.e., the coversheet herein. Said another way, such agents make the surface of the coversheet more sticky and adherent to solid matter such as lint, hair, dust, pollen, and the like.
  • internal surface of the coversheet herein is meant that surface which faces the absorbent substrate.
  • external surface herein is meant that surface which faces away from the substrate, i.e., faces outwardly from the article. It is this face which comes in direct contact with the fabrics being treated.
  • the coversheet herein should be of a thickness which effectively provides the physical barrier function. Even though made from hydrophobic fibers, if the coversheet is too thin, fluid passage can occur under the intended usage conditions. Accordingly, it has now been determined that the thickness of the fibrous coversheet should preferably be at least about 7 mils (0.18 mm), preferably from about 0.2 mm to about 0.6 mm. It has also been determined that the fibers used in the coversheet are preferably hydrophobic and preferably have a melting point above about 204°C.
  • Fibrous coversheets for use herein can readily be made from non-heat resistant fibers such as polyethylene.
  • preferred fibrous coversheets can be prepared using nylon (especially nylon-6), polyester, and the like, heat-resistant fibers which can withstand even inadvertent misuse in the present process.
  • the flexible, cloth-like, permeable topsheets made therefrom are conventional materials in the art of nonwoven and woven fabric making, and their manufacture forms no part of the instant invention.
  • Nonwoven fabrics for use as coversheets are available commercially from companies such as Reemay, Inc., Hickory, TN.
  • Such coversheets also pick up solid dust particles, vagrant lint and other fibers from the fabrics being treated in the present process, thereby enhancing the overall clean/refreshed appearance of the fabrics following the treatment herein.
  • nonwoven or woven fibrous sheet materials can be used in a flat single layer or as multiple layers as the coversheet for the absorbent carrier core herein.
  • the absorbent core carrying the cleaning/refreshment composition is enrobed in a polyester or polyamide fibrous coversheet which has been ring rolled or otherwise crimped to provide three dimensional bulk.
  • this coversheet may be further covered by a second coversheet in an uncrimped configuration.
  • Such fibrous, preferably heat resistant and, most preferably, hydrophobic, coversheets thus provide various embodiments of the article herein. Suitable combinations can be employed, according to the desires of the manufacturer, without departing from the spirit and scope of the invention.
  • the coversheet can be provided with macroscopic fenestrations through which the lint, fibers or particulate soils can pass, thereby further helping to entrap such foreign matter inside the article, itself.
  • the preferred venting bag is provided with a vapor-venting closure which provides one or more gaps through which vapors are released from the bag, in-use.
  • the size of this gap is selected to provide controlled vapor release from the bag under the indicated operating conditions. While other gap sizes and operating conditions can be used, a preferred balance between vapor containment within the bag to perform the sanitization of the fabrics along with the cleaning/refreshment function and vapor release from the bag has now been determined using the principles disclosed hereinafter.
  • the design of the venting ability of the bag achieves a proper balance of the above effects.
  • a tightly-sealed, vapor impermeable "closed” bag will not purge malodors and will overly moisten the fabrics, resulting in wrinkling.
  • An overly “open” bag design will not sufficiently moisten the fabrics or soils to mobilize heavier malodors or to remove pre-existing fabric wrinkles. Further, the bag must be “closed” enough to billow and create a void volume under water vapor pressure, wherein the fabrics can tumble freely within the bag and be exposed to the vapors.
  • the containment bags herein can also be prepared using sheets of co-extruded nylon and/or polyester or nylon and/or polyester outer and/or inner layers surrounding a less thermally suitable inner core such as polypropylene.
  • a bag is constructed using a nonwoven outer "shell” comprising a heat-resistant material such as nylon or polyethylene terephthalate and an inner sheet of a polymer which provides a vapor barrier.
  • the non-woven outer shell protects the bag from melting and provides an improved tactile impression to the user.
  • the objective is to protect the bag's integrity under conditions of thermal stress at temperatures up to at least about 400- 500°F (204°C to 260°C). Under circumstances where excessive heating is not of concern, the bag can be made of polyester, polypropylene or any convenient polymer material.
  • the Vapor- Venting Equilibrium for any given type of vapor-venting closure will depend mainly on the temperature achieved within the dryer - which, as noted above, is typically reported as an average "dryer air temperature". In point of fact, the temperature reached within the containment bag is more significant in this respect, but can be difficult to measure with accuracy. Since the heat transmittal through the walls of the bag is rather efficient due to the thinness of the walls and the tumbling action afforded by conventional clothes dryers, it is a reasonable approximation to measure the WE with reference to the average dryer air temperature.
  • Each garment is placed in the bag being evaluated for vapor venting along with the water-containing substrate (removed from its pouch and unfolded).
  • This step can be conducted for longer or shorter periods, depending on such factors as the degree and type of soiling of the fabrics, the nature of the soils, the nature of the fabrics, the fabric load, the amount of heat applied, and the like, according to the needs of the user.
  • greater than about 40% typically 40% to about 80%, of the moisture is vented from the bag.
  • a low residue liquid fabric cleaning/refreshment product for use preferably in a vented dryer bag is prepared, as follows.
  • any plastic or flexible pouch which does not leak is suitable for use herein.
  • a foil laminated pouch of the type used in the food service industry can be employed.
  • Such pouches are well-known in the industry and are made from materials which do not absorb food flavors.
  • the formulator herein may wish to avoid abso ⁇ tion of the perfume used in the cleaning/refreshment composition by the pouch.
  • Various pouches are useful herein and are commercially available on a routine basis.
  • the pouch containing the rolled/folded article herein has overall dimensions of about 8.5 cm x 17.7 cm, whereas a pouch for a similar planar-folded article is about 13 cm x 17.7 cm. A savings in material of about 30-40%) is thus achieved.

Abstract

On améliore des articles prévus pour le nettoyage/rafraîchissement du linge sale en texturant au moins une surface de l'article et/ou en y appliquant des agents collants. Pendant l'utilisation, les articles en question frottent contre les tissus à nettoyer et les peluches détachées du tissu sont piégées et retenues par l'agent collant. On réduit au minimum la tendance de ces articles à retrouver l'état plié dans lequel ils étaient conditionnés, en conférant une texture à une ou plusieurs des surfaces de l'article en question.
