Definitions

  • the present invention relates to a method for treatment of impregnated clothes, preferably firemen's clothing, in an ordinary drum type laundry washing machine, said clothes having water and oil resistant properties.
  • the invention is applicable to firemen's clothing made of a material named NOMEX and comprising three layers, namely an outer cloth, a wadding layer and an inner lining.
  • NOMEX a material named NOMEX
  • the material is flameproof.
  • the glass transition temperature is in the range of 250-400°C wheras the melting point is above 400°C.
  • Fire cloths are provided with reflective strips due to which said cloths must not be washed at a temperature exceeding 60°C. After repeated washings the oil resistant properties, in particular, deteroriate which results in a need for reimpregnation of the cloths after wash.
  • a wash in a wash solution comprising a soapless detergent may cause the oil resistant properties to recover to a certain degree. In the case of normally and heavily solied garments, however, no such improvement is obtained.
  • An object of the invention is to provide a method for treatment of impregnated cloths, especially firemen's clothing, having water and oil resistant properties, said treatment being such that the cloths be cleaned and at the same time the oil resistant properties recover which have got lost by use and by the wash of said cloths.
  • Another object of the invention is to provide a machine for washing and reimpregnation of the garments in accordance with said method.
  • the oil fastness Prior to wash the oil fastness had a value of 6 (as measured in accordance with a predetermined method named "AATCC Test Method 118-1983") while after three washes the value had lowered to 2-3.
  • the garments contained a rest humidity of 20% after spindrying. Subsequent to each wash a tumble drying cycle took place in a machine of the type indicated at 85°C for ca. 20 minutes. Then, the garments were overdryed for another 30 minutes whereafter the temperature of the garments was measured to be 95°C. Finally, the fire men's clothes were reimpregnated in an impregnation liquid of the type Querophob BSN at a dosage of 10 g/I.
  • This liquid can be described, more specifically, as a liquid solution of a cationic fluoric carbon resin. Accordingly, in the washing machine referred to the dose amounted to 300 g in a wash bath of 30 I.
  • the reimpregnation program program No. 5 in the program chart
  • the impregnation lasts for 35 minutes and ends by a spin-drying cycle of 6 minutes.
  • the garments were tumble dried for 50 minutes in a tumble drier of the type indicated.
  • the oil fastness was measured to be 5-6 after reimpregnation.
  • the lightly soiled garments were washed according to program No. 1, see the program chart of Fig. 2.
  • the dosage of detergent amounted to 50 g of Bio Luvil Special and the program was running for 42 minutes.
  • the program comprised a main wash for 12 minutes, three rinses of 2 minutes each, a final rinse of 3 minutes and a final spindrying cycle of 6 minutes.
  • the garments looked clean after being washed but reflective strips disposed on the garments had remaining black stains.
  • the lining was lightly gray (coloured).
  • the garments were dryed in a tumble drier of the type Wascator TT 210 for 50 minutes. Thereafter, the oil fastness was measured and the value was found to be 4. After that, the garments were reimpregnated according to program No. 5, see the program chart, in the washing machine indicated. Impregnation took place at 40°C and with the bath containing 250 g of BSN. After spin-drying the garments were dryed in the tumble drier mentioned for 50 minutes. Then, the oil fastness was measured to be 5-6.
  • the oil fastness was measured to be 1-2 on the leg of the trousers whereas the value 2-3 was obtained higher up on the trousers where the jacket could provide protection to some extent. After reimpregnation according to program No. 5, see the program chart, the oil fastness was measured to be 5-6.
  • the heavily soiled garments were washed in accordance with program No. 3, see the program chart.
  • the dosage was 50 g of Bio Luvil Special in the prewash and the same dose was used in the main wash.
  • the program lasted for 54 minutes.
  • the program comprises a prewash for 6 minutes and a main wash for 15 minutes.
  • the program proceeds through rinses and a final spin-drying cycle as in programs Nos. 1 and 2.
  • Microemulsion and HAMIX have shown to be efficient on the type of soil present on firemen's clothing.
  • the impregnation bath can be reused several times which is suitable for cost and environmental reasons.
  • a washing machine is schematically shown which is suitable both for washing and reimpregnation.
  • the machine is of the common type comprising a tub 11 enclosed in a cabinet 10.
  • a drum 12 for supporting the garments to be treated is rotatably disposed in the tub.
  • the drum is driven by an electric motor 13 of any suitable kind and the machine is functionally controlled by a program control device 14, usually named programmer.
  • the machine has a water inlet 15 and water is supplied to the machine via an ordinary solenoid valve 16.
  • a heating element 26, also of common type, is provided in the tub for heating of treatment liquid to a desired temperature.
  • the machine is of the type having its drain 17 positioned at a low point and provided with a first drainage valve 18 to which a branch 19 is connected. Via a second drainage valve 20 said branch is connected to an exterior drainage.
  • the branch 19 is connected to a tank 22 containing impregnating liquid.
  • the extracted impregnation liquid flows back into the tank 22 to be reused in further impregnation cycles.
  • the separate valve 21 is closed while the second drainage valve 20 is opened. Then, the machine is ready for another washing or impregnation process.
