Definitions

  • This invention relates to the finishing of fabric and more specifically to the finishing of fabric in a manner to provide the fabric with effective water-repellant and insecticidal properties.
  • a synthetic pyrethroid permethrin is known for its repellant as well as knockdown and kill activity.
  • Permethrin effectively controls a variety of pests, such as ticks, cockroaches, houseflies, mosquitoes, and other insects/arthropods.
  • Permethrin has had very limited use in weathered applications due to its decomposition into a nonactive, non-insecticidal product in the presence of oxygen and ultraviolet light.
  • U.S. Pat. No. 4,056,610 (11/1997) to Barber, Jr. et al. discloses a microcapsule insecticide composition with a polyurea shell having U.V. absorbing compounds, in which a pyrethroid permeates a porous shell wall and maintains an effective level of the pyrethroid upon the outer surface of the shell wall to control insects up to four days. Control is achieved by killing insects which contact the pyrethroid released through the capsule wall.
  • the capsules are spread out in various ways and are incorporated into sheet materials such as tapes.
  • U.S.Pat. No. 4,765,982 (8/1988) to Ronning and Gregg discloses an insect control device comprising a plurality of rough- surfaced cellulosic fibers, made from a graft copolymer cellulose and an etylenically unsaturated material copolymerizable with cellulose. Wherein a liquid insecticide composition microencapsulated in a capsule, whose shell is permeable to the liquid insecticide is self-adhered to the surface of the fibers.
  • the preferred microencapsulated insect control agents for use in Running's invention are those disclosed in U.S. Pat. No. 4,056,610 to Barber.
  • Ronning' s insecticide treated, rough surfaced cellulosic fibers are formed into webs, tapes, sheets, pads, and various other relatively flat shapes to maximize the surface area of the device. These devices are made suitable for use in particular locations, such as a circular sheet for the top of a silo or a ribbon-like tape for placement along the base of a building or door.
  • Ronning teaches that smooth-surfaced synthetic fiber-forming materials such as polyester and nylon do not act as good sites for adhesion of microencapsulated insect control agents.
  • Running's rough-surfaced cellulosic fibers treated with an insecticide are not suitable for a tent fabric. The texture of the rough surfaced fibers is not satisfactory and they are neither water repellant or flame retardant.
  • U.S. Pat No. 4,833,006 (5/1989) to Mc. Kinney discloses a flame resistant and water-repellant coating for fabric that contains a polyfunctional isocyanate as an adhesion promoter and binder to adhere the coating to the substrate in a flake proof manner.
  • the coating compositions are preferably applied in a liquid state to the fabric and then processed at a temperature of 190°C (375°F) to fuse the coating composition to the fabric substrate
  • U.S. Pat No. 5, 198,287 (3/1993) to Samson discloses a tent fabric which is coated in a sandwich structure.
  • the fabric is coated on the outside with a water-repellant flame resistant coating, and the inside is coated with a different water-repellant flame resistant coating in which permethrin is incorporated at a concentration of 2.58 g/m 2 active. It is preferred that the outside coating be the described and claimed coating in U.S. Pat. No. 4,833,006
  • U.S. Pat No. 5,252,387 (10/1993) to Samson is an improvement to U.S.Pat. No. 5, 198,287 by using external barriers to prevent migration of the permethrin to the outside surface.
  • These barriers include polymeric coatings, films, foils, fabrics, and surface treatments which are resistant to plasticizer migration.
  • This invention provides a safe, efficient, inexpensive, easy to apply water-repellant insecticide for use by individuals on small lightweight hiking tents or other substrates that may require these features.
  • Figure 1 is a perspective view of the tent
  • Figure 2. is a sectional view taken substantially along the line A- A in figure 1.
  • Figure 3 is a chart illustrating the durability of the product by demonstrating the percentage of mosquitoes dead or unable to fly with respect to the bright-sunshine hours of exposure and the fabric life/strength remaining.
  • the fabric or substrate suitable for this invention can be any light weight fabric suitable for the manufacture of tents or structures of limited size.
  • Applicants treat the light-weight hiking tent fabric or substrate with a low concentration of the insecticide EVERCIDE*Perrnethrin combined in solution with an air-drying, air-curing silicone fabric finish which serves as a water-repellant.
  • This solution impregnates the fabric in a homogeneous manner, and provides water-repellancy and insecticidal properties without affecting the breathability or the feel of the fabric.
  • This treatment will cure at room temperature and can be applied using a hand pumpspray, aerosol or paintbrush to the tent, or during normal commercial finish operations on the manufactured fabrics.
  • Water-repellant with insecticide for treating light-weight tent fabric For treating light-weight tent fabric.
  • Ultra violet radiation along with Oxygen (O 2) are the major components associated with weathering degradation.
  • a water-repellant coating must repel water, it therefore helps prevent oxygen in moisture to come in contact with and diffuse into fibers or coating, thus reducing the rate of degradation. If this coating also has natural U.V. absorbing properties, which can further be enhanced by additives, it may be possible to reduce the degradation rate of the fabric or coated products.
  • the application method, water-repellant coating durability, and U.V. properties of the water-repellant are also a concern.
  • the silicone finish is very stable in the presence of U.V. radiation and in addition to serving as a water-repellant, the silicone finish acts as a plasticizer by coating the permethrin and creating a permeable shell around the permethrin.
  • the silicone finish prevents the permethrin from degrading rapidly while providing a sustained release of the insecticide to the fabric.
  • the water-repellant insecticide solution will be applied to the outside of the tent illustrated in figure 1
  • the solution can be applied to a tent using a hand pumpspray, aerosol or paintbrush Application of the solution would be hazardous inside the tent due to the restricted space and wall inclination
  • Unfinished tent fabric/substrate can be commercially treated du ⁇ ng normal industrial finish operations
  • the solution should be applied in a fashion that completely saturates the fab ⁇ c as illustrated in figure 2
  • Such a homogeneous application will deposit approximately 0 25 g/m 2 of permethrin within a light-weight tent fabric This amount corresponds to 10 3 times less permethrin then applied to tents treated by Samson U S Pat No 5, 198,287 and 5 times less then accepted level allowed on clothing by the E P A
  • the effectiveness of the permethrin as an insecticide has been field tested for a duration of 163 1 bright sunshine hours in the months of July and August Measurement of bright sunshine hours or U V -B radiation provide a better method for measu ⁇ ng degradation caused by weathering exposure than months or days of exposure, because they do not take into account the shorter days of winter, and rainy days when the rate of degradation is reduced
  • the water-repellant insecticide was evaluated using mosquitoes to determine i ) That the natural behaviour of the mosquitoes to land on the walls of the tent would not be influenced by the insecticide repellant properties of the permethrin ii ) The number of mosquitoes dead or unable to fly (knockdown, KD) inside the tent after an exposure of three hours iii) The duration of insecticide treatment when exposed to weathering
  • the treated fabric showed no insecticide repellant effect but excellent insecticide properties and that the natural behaviour of the mosquitoes remained unaltered.
  • the mosquitoes immediately flew and held to the roof and walls of the tent and remained there without the need to move around. After a period of about fifty minutes the smaller mosquitoes began to lose grip, and eventually fall to the floor, while the larger ones began to show signs of intoxication. After the exposure of three hours the mosquitoes dead or alive were counted.
  • the untreated tent showed no dead mosquitoes within the three hour time frame. After the tent had been exposed for 161.3 hours, 243 mosquitoes were let free inside the tent, of which 95% died in the first three hours.
  • Figure 3 is a chart illustrating the durability of the product by the percentage of mosquitoes dead or unable to fly with respect to the bright-sunshine hours of exposure and the fabric life/ strength remaining.
  • the tent be retreated to maximize the efficiency of both the water-repellant and insecticide properties. Protection by the water-repellant insecticide coating may be longer if the tent is exposed in; an intermittent fashion, in the shade, or in cooler times of the year when temperature and UN. radiation aren't as high.
  • the following composition is exemplary of the solution that can be used in practice to reduce mildew formation, on tent/substrate that are exposed to high humidity environments.
  • Water-repellant with insecticide and mildewcide for treating light-weight tent fabric Water-repellant with insecticide and mildewcide for treating light-weight tent fabric.
  • Fabric/substrate treated with this solution offers good mildewcide properties and may prolong fabric/substrate life due to the natural U.V. absorbing properties of Skane M-8 and zinc-oxide mildewcide products.
  • the fabric was exposed to weathering in a damp environment oriented vertically and facing due north to maximize the growth of mildew on the surface. After three months of exposure, the control non-treated fabric was covered with mildew, while the treated fabric showed little or no signs of mildew.
  • the improvement comprises in treating a lightweight hiking tent fabric homogeneously in a one step application, with a water-repellant and insecticide finish, that will not affect the fabric properties, appearance or feel, and will have a duration of at least 163.1 bright sunshine hours.
  • this invention provides a safe, efficient, inexpensive easy to apply water-repellant insecticide for use by individuals in domestic application or by companies in industrial application, on small lightweight hiking tents or other substrates that may require these properties.
  • a treated fabric according to claim 1. wherein the water-repellant is an air-drying, air-curing silicone fabric finish.
  • a treated fabric according to claim 1. to which may be added the mildewcide, 2-n-octyl-4- isothiazolin-3-one.
