Definitions

  • the invention concerns on the one hand a method of producing a fabric with insect repellent characteristics in which a solution comprising an insect repellent product and a binding agent is introduced onto the fabric as well as a fabric produced by a similar method on the other hand.
  • the invention concerns more particularly the enhancement of the retention of permethrin in fabrics during successive washes.
  • Permitrine is an insect repelling agent and is a member of the pyrethrum based substances. Because permitrine is quickly broken down, synthetic permitrine is often used in practice. It is principally used to repel or kill cold-blooded insects like mosquitoes.
  • permitrine Because of its insect repellent qualities, permitrine is often applied to fabrics, knitwear, non-woven, etc.... However, due to the weak permanence of permitrine, this insect repellent has the disadvantage that after only a few washes it is completely expelled from the fabric. Consequently, fabrics need to be re-treated with an insect repellent product after washing. This procedure has the disadvantage that it leads to increased costs as well as being damaging to the environment.
  • the European patent request EP 0 787 851 describes two ways of introducing and applying permitrine into fabrics.
  • the fabric is impregnated with a binding agent (acrylic binder), permitrine and where necessary also with a cross-linking agent.
  • a second process treats only one side of the fabric surface with permitrine and binding agent.
  • an insect repellent product is described that can be applied to fabric.
  • the specified product contains an insect repellent product (DEET) and an oil-attracting product, particularly an elastomer. Varying the amount of elastomer controls the measure whereby the insect repellent product is released.
  • DEET insect repellent product
  • oil-attracting product particularly an elastomer. Varying the amount of elastomer controls the measure whereby the insect repellent product is released.
  • the aim of the invention is to provide a method of producing a fabric with insect repellent properties whereby the insect repellent product stays active in the fabric even after a large number of washes.
  • this patent request means at least 60, preferably 60 to 100 washes and, in particular, to in excess of 100 washes.
  • the aim of the invention is accomplished by the application of a method for making fabrics with insect repellent properties in which a solution comprising an insect repellent product and a binding agent are applied to a fabric wherein said insect repellent product is permethrin and wherein in the solution a combination of an acrylate binding agent and a silicon elastomer is added in order to enhance the retention of the permethrin during successive washes of the fabric.
  • Acrylate is the binding agent.
  • the named solution is applied in a preferential operation on fabrics, knitwear or on non-wovens. By adding the combination elastomer/acrylate the insect repellent product remains much longer on the fabric during successive washes.
  • the specified solution should also contain an anti - foam agent, preferably on the basis of dimethylpolysiloxane and a moistening agent.
  • the amount of acrylate in the solution amounts to at least 20 g/l, in particular at least 90 g/l acrylate.
  • the quantity of acrylate in the solution lies in particular between 20 and 250 g/l.
  • the amount of elastomer in the solution amounts to at least 20 g/l and is preferably between 20 and 60 g/l and amounts to more by particular 50 g/l.
  • the amount of permethrin in the solution should be between 10 and 250 g/l, preferably between 20 and 150 g/l, and more in particular between 20 and 50 g/l.
  • Other insect repellent products that can be used by preference are cyfluthrine and deltamethrine.
  • a particular preferential method for the manufacturing of a fabric with insect repellent properties is that the specified solution is applied to the fabric via impregnation, a spray, coating, lick roll or other known method whereby the fabric is preferably pressed out between two rolls. After this the fabric is dried in a dry unit at a minimum temperature of 110 °C.
  • the method can by preference be applied to non-wovens, knitwear or fabrics such as cotton, polyester/cotton, flax, flax/cotton, polyamide, polyamide/cotton, polyester, polyester/viscose, meta aramide, meta aramide/cotton, modacryl, modacryl/cotton, viscose/cotton or combinations thereof.
  • Another subject of this invention is a fabric with insect repellent properties provided with a solution comprising an insect repellent product and a binding agent, wherein the said insect repellent product is permethrin and wherein the said solution has a combination of an acrylate binding agent and a silicon elastomer added in order to enhance the retention of the permethrin on the fabric.
  • the fabric hereby retains its insect repellent properties during successive washes. Tests have shown that the fabric retains its insect repellent properties when washing at 60°C for at least 60 washes, by preference between 60 and 100 washes and more.
  • the fabric is preferably manufactured by a method according to any one of the claims 2 up to and including 7.
  • This patent request further contains the use of the combination acrylate / elastomer, in particular silicon elastomer as a retention increasing agent in a solution comprising an insect repellent product.
  • the insect repellent product remains on the fabric much longer, especially the permethrin, during successive washes.
  • the fabric is impregnated, for example by means of dip coating with a solution comprising an insect repellent product, an acrylate and an elastomer, preferably a silicon elastomer, a moisture agent and an anti foam agent.
  • a solution comprising an insect repellent product, an acrylate and an elastomer, preferably a silicon elastomer, a moisture agent and an anti foam agent.
  • the resulting solution is then continually fed in an application bath that allows the full breadth of the fabric to be impregnated.
  • the solution can likewise be applied discontinued.
  • the specified fabric is uniformly pressed out between two rolls with a specific hardness.
  • the hardness of the rolls similarly determines the absorption of the solution because the harder the rolls, the higher the pressing out level and the less the absorption.
  • the fabric is dried in a drying unit at a temperature of at least 110 °C.
  • the drying unit consists of various units each with its own heating and air circulation with control aggregates. After drying, the fabric comes into a cooling zone with air followed by contact cooling.
