Definitions

  • the present invention is for method and means by manufacture of wad containing cushions and padding for furniture and seats for home, office, public places and chairs and other products for vehicles.
  • the filling of the covers means a manual work which may not be disregarded even if it has been tried to automate the procedure.
  • the covers are often sewn in a special way and may be divided into channels or similar, separate sections. It is also known in the art to shape the cushions by putting a mixture of polyester fibres into a mould. Some of the fibres are so called melt fibres which will melt fully or partially at a consecutive heating and then will bind adjacent fibres.
  • Polyester fibres offer many advantages compared to polyurethane. It is easily recovered and it does not pollute neither the external nor the internal environment during the process of manufacture or during the use of the product. Moreover polyester fibres do not attract moisture or dirt and are neutral to allergy, i.e. it does not cause allergies and is not dangerous to allergic persons.
  • the present invention is for method and means by the manufacture of wad containing cushions and corresponding padding materials having desired weight and density and possibility to obtain different properties at separate sections of the products.
  • the invention makes it possible to shape mould polyester fibre products.
  • a cover from non-woven material having a melting point below 100 °C.
  • the cover is then filled with a mixture of 10-30 % w/w, preferably 20 % w/w meltable fibre and 70-90 % w/w, preferably 80 % w/w of polyester fibres of a material which is non-meltable or which does not melt at the temperatures which may occur during the process. Filling may take place in known manner using vacuum.
  • the filled cover, or the polyester cut to shape is then put into a mould which allows hot air to flow into and through the cover and the filler.
  • the temperature of the air is 120-170 °C, suitably 130-160 °C and preferably 135 °C.
  • Blowing of air goes on for a time interval of 20 s - 10 min, usually 30 s - 5 min and preferably 30 s - 1 min.
  • the surrounding cover and the meltable fibres of the filling will then melt. This gives as result cushions of homogenous material which have a very good shape stability. Textiles may also in this way be fixed by moulding and form a homogenous unit with the filling.
  • the weight per volume of the product when ready may be varied within an interval of at least 20-50 kg/m 3 .
  • This may be made use of by that separate channels or sections within a cover are filled to different weight per volume when manufacturing for example cushioning for vehicle seats, where a softer middle section forms the back and/or seat and more firm side sections form supporting cushions at the sides of the back and/or the seat.
