Definitions

  • the present invention relates to moistened disposable wipes for household and automotive use for the control of indoor allergens.
  • the present invention also relates to a method for cleaning and reducing allergens from fabric-based materials around the home and automobile utilizing the moistened wipes of the present invention.
  • House dust is comprised of many components. While its content can vary considerably, a speck of dust can contain fabric fibers, human skin particles, animal dander, house dust mites, parts of cockroaches, mold spores, bacteria, food particles, and other debris. For numerous individuals, many of these dust components are allergenic, including the most common culprits, dust mites, pet dander, and mold spores. One dust particle may contain an agglomeration of these various components. These components are often associated with the onset of a runny or stuffy nose, itchy/watery/red eyes, and sneezing for allergy sufferers. Unfortunately, house dust is present even in "clean" homes. Some of the common reservoirs of indoor allergens include the fabrics of bedding, upholstery, drapery, and carpets.
  • Laundering is one approach to combat dust allergens. Yet, for many home fabrics, such as upholstery and draperies, washing or dry-cleaning are not easy or readily available options. As a result, consumers will often report that they clean these articles routinely by vacuuming. Yet, in actuality, "routinely" translates into vacuuming the upholstery and draperies once or twice yearly, or cleaning the fabric surfaces with a dust cloth or old T-shirt a couple of times monthly. Undoubtedly, vacuuming and dusting may reduce the level of dust in home fabrics; however, it is believed that there are many dust components, including allergens, that are very difficult to remove by these measures (American College of Allergy, Asthma, & Immunology On-Line, Public Education: Indoor Allergy Survival Tips, 2005).
  • This present invention embodies a moistened disposable wipe uniquely designed to remove allergens from fabric surfaces.
  • the moistened, disposable wipe quickly, easily, and gently removes dirt and contamination from the surfaces of fabrics without fraying and without leaving lint behind.
  • the moistened disposable wipe also removes allergens (typically very small in size, generally ranging from about 0.1 micron to 100 microns) from fabric surfaces so that they can be placed in the garbage and not in the air or home, while at the same time depositing allergen control agents on the fabric surface contacted by the wipe.
  • the present invention relates to a moistened disposable wipe for cleaning household fabric-based materials.
  • the wipe comprises a substrate and a composition.
  • the composition comprises: i) from about 0.01% to about 25% by weight of an allergen control agent; ii) from about 0.05% to about 15% by weight of an organic solvent; and iii) balance water and optional components.
  • the present invention also relates to a method for cleaning household surfaces.
  • the method comprises the steps of: a) providing a disposable wipe wherein the disposable wipe comprises: a substrate which is comprised of at least one ply which includes a composition applied to the substrate wherein the composition is applied to the substrate in the amount of from about 0.5 grams of the composition/gram of the substrate by weight to about 8 grams of the composition/gram of the substrate by weight.
  • the composition comprises: i) from about 0.01% to about 25% by weight of an allergen control agent; ii) from about 0.05% to about 15% by weight of an organic solvent; and iii) balance water and other optional components; b) contacting the surface to be cleaned with the disposable wipe; c) applying the composition to the surface; and d) transferring dirt and contaminants from the surface to the disposable wipe.
  • the present invention additionally relates to a kit for cleaning household surfaces.
  • the kit comprises: a) a moistened disposable wipe comprising a substrate which is comprised of at least- one ply which includes a composition applied to the substrate wherein the composition is applied to the substrate in the amount of from about 0.5 grams of the composition/gram of the substrate by weight to about 8 grams of the composition/gram of the substrate by weight.
  • the composition comprises: i) from about 0.01% to about 25% by weight of an allergen control agent; ii) from about 0.0.01% to about 15% by weight of an organic solvent; iii) balance water; and b) an implement to which the moistened disposable wipe is attached for facilitating contact of the moistened disposable wipe to the household surface.

  • the substrate of the present invention may be comprised of one or more plies.
  • the substrate may comprise woven and/or nonwoven, unmodified and/or modifed natural fibers (one non-limiting example of which is a cellulosic-based fiber such as wood pulp fiber), synthetic fibers, or mixtures thereof.
  • Suitable synthetic fibers include but are not limited to polyvinyl chloride, polyvinyl fluoride, polytetrafluoroethylene, polyvinylidene chloride, polyacrylics such as ORLON ® , polyvinyl acetate, rayon, polyethylvinyl acetate, non-soluble or soluble polyvinyl alcohol, polyolefins such as polyethylene (e.g., PULPEX ® ) and polypropylene, polyamides such as nylon, polyesters such as DACRON ® or KODEL ® , polyurethanes, polystyrenes, and the like, including fibers comprising polymers containing more than one monomer.
  • the fibers useful herein can be hydrophilic, hydrophobic, or can be a combination of both hydrophilic and hydrophobic fibers. As indicated above, the particular selection of hydrophilic or hydrophobic fibers depends upon the other materials included in the absorbent (and to some degree) the scrubbing layer described hereinafter. Suitable hydrophilic fibers for use in the present invention include cellulosic fibers, modified cellulosic fibers, rayon, cotton, polyester fibers such as hydrophilic nylon
  • hydrophilic fibers can also be obtained by hydrophilizing hydrophobic fibers, such as surfactant-treated or silica-treated thermoplastic fibers derived from, for example, polyolefins such as polyethylene, polypropylene, polyacrylics, polyamides, polystyrenes, polyurethanes and the like.
  • hydrophobic fibers such as surfactant-treated or silica-treated thermoplastic fibers derived from, for example, polyolefins such as polyethylene, polypropylene, polyacrylics, polyamides, polystyrenes, polyurethanes and the like.
  • Suitable wood pulp fibers include those obtained from well-known chemical pulping processes such as the kraft and sulfite processes. It may be desirable to derive these wood pulp fibers from southern softwoods due to their premium absorbency characteristics. These wood pulp fibers can also be obtained from mechanical pulping processes, such as stone groundwood, refiner mechanical, thermomechanical, chemimechanical, and chemi-thermomechanical pulping processes. Recycled or secondary wood pulp fibers, as well as bleached and unbleached wood pulp fibers, can also be used.
  • hydrophilic fiber which may be used in the present invention is chemically stiffened cellulosic fiber.
  • chemically stiffened cellulosic fiber means cellulosic fibers that have been stiffened by chemical means to increase the stiffness of the fibers under both dry and aqueous conditions. Such means can include the addition of a chemical stiffening agent that, for example, coats and/or impregnates the fibers. Such means can also include the stiffening of the fibers by altering the chemical structure, e.g., by crosslinking the polymer chains.
  • the fibers can optionally be combined with a thermoplastic material. Upon melting, at least a portion of this thermoplastic material migrates to the intersections of the fibers, typically due to interfiber capillary gradients. These intersections become bond sites for the thermoplastic material. When cooled, the thermoplastic materials at these intersections solidify to form the bond sites that hold the matrix or substrate of fibers together in each of the respective layers. This can be beneficial in providing additional overall integrity to the cleaning wipe.
  • Suitable methods include but are not limited to spunbonding, meltblowing, carding, wet laying, and airlaying.
  • Suitable techniques for binding the fibers of the substrate together include but are not limited to hydroentangling, needle punching, thermal bonding, ultrasonic bonding, chemical bonding, surface treating, and laminating.

  • Suitable thermoplastic materials can be made from any thermoplastic polymer that can be melted at temperatures that will not extensively damage the fibers that comprise the primary substrate or matrix of each ply. Typically, the melting point of this thermoplastic material will be less than about 190 0 C, and generally between about 50 0 C and about 175 0 C.
  • thermoplastic fibers can be made from a single polymer
  • Sheath/core bicomponent fibers refers to thermoplastic fibers that comprise a core fiber made from one polymer that is encased within a thermoplastic sheath made from a different polymer.
  • the polymer comprising the sheath often melts at a different, typically lower, temperature than the polymer comprising the core.
  • these bicomponent fibers provide thermal bonding due to melting of the sheath polymer, while retaining the desirable strength characteristics of the core polymer.
  • Suitable bicomponent fibers for use in the present invention can include but are not limited to sheath/core fibers having the following polymer combinations: polyethylene/ polypropylene, polyethylvinyl acetate/polypropylene, polyethylene/polyester, polypropylene/polyester, copoly ester/poly ester, and the like.
  • Particularly suitable bicomponent thermoplastic fibers for use herein are those having a polypropylene or polyester core, and a lower melting copolyester, polyethylvinyl acetate or polyethylene sheath (e.g., those available from Danaklon a/s, Chisso Corp., and CELBOND®, available from Hercules).
  • sheath/core bicomponent fibers can be concentric or eccentric.
  • concentric and eccentric refer to whether the sheath has a thickness that is even, or uneven, through the cross-sectional area of the bicomponent fiber: Eccentric bicomponent fibers may be desirable in providing more compressive strength at lower fiber thicknesses.
  • Another method of bonding the fibers is chemical bonding.
  • Common chemical bonding agents include but are not limited to solvent based and resin based adhesives (e.g.- latex, etc.).
  • the wipe may also be comprised of a HIPE-derived hydrophilic, polymeric foam.
