Definitions

  • the invention is related to a soleplate having a support provided with a contact layer for ironing a piece of garment.
  • the invention is further related to an iron and a method of manufacturing a sole plate.
  • a PTFE soleplate coating has good non-stick, i.e. a good stain resistance, and good ironing smoothness, however the scratch resistance and wear resistance of such a coating are poor.
  • PEEK may be considered as top coating on a soleplate material.
  • PEEK has known favorable properties like a low friction coefficient, good mechanical properties and a good wear resistance compared to PTFE coatings.
  • PEEK soleplate coatings are susceptible to stain. In case a stain (e.g. dyes and / or burned fabric which are released from the garments upon ironing) is attached to the soleplate, the gliding properties of the coating may be affected negatively (gliding becomes draggy, less smooth). Furthermore no the stain is desired from an aesthetical point of view.
  • a stain e.g. dyes and / or burned fabric which are released from the garments upon ironing
  • It is an object of the invention provide a soleplate comprising a contact layer having a good wear resistance and good stain resistance.

  • a fluoropolymer content of less than 10% may reduce the stain resistance to an undesired level.
  • the fluoropolymer is polytetrafluoroethylene or polyfluoroalkoxy or a mixture thereof.
  • the heat resistance of these fluoropolymers makes these polymers suitable for use a soleplate for an iron.
  • the soleplate comprises an intermediate layer interposed between the soleplate and the contact layer.
  • the intermediate layer may increase the corrosion resistance of the soleplate.
  • the intermediate layer preferably comprises a polytetrafluoroethylene, a polyetheretherketone or a mixture thereof.
  • both the contact layer and the intermediate layer comprise the blend of PEEK and the fluoropolymer, both layer have the good wear and stain resistant properties. These properties have a favourable effect on the lifetime of the soleplate, wherein the soleplate has good wear resistance and good stain resistance properties for a prolonged lifetime. Multiple intermediate layers may be applied.
  • the contact layer is provided with a cladding layer, the cladding layer having the garment contact surface.
  • the contact layer and the cladding layer together form a composite contact layer.
  • the cladding layer may be a PTFE layer or a PFA or PEEK layer.
  • the contact layer has a thickness in a range of 10-100 micron.
  • the contact layer having a thickness of at least 10 micron ensures that a layer of homogeneous thickness, over the surface it is applied to, is obtained ( ⁇ 10 % layer thickness).
  • a layer having a thickness of maximum ca. 40 micron may be applied in one spray layer.
  • a practical contact layer is the contact layer in a range of 10- 40 micron.
  • a way to obtain the contact layer having a thickness of at least 45 micron is to apply multiple layers.
  • a first layer may be applied on the substrate and dried, subsequently a second layer may be applied on the first layer and dried, and thereafter a third layer may be applied on the second layer.
  • the three layer are cured.
  • the iron according to the invention has a body comprising a soleplate having a contact layer comprising a mixture of polyetheretherketone and a fluoropolymer.
  • the soleplate on the iron may have any of the features described above.
  • the iron has the benefits of the soleplate according to the invention.
  • the iron may be a dry iron or a steam ironing device.
  • the temperature of the soleplate is kept at a desired temperature by means of a thermostat and a temperature dial.
  • the number of dots on the temperature dial indicates the temperature of the soleplate of iron:
  • Steam is generated by a steam generator, which comprises a water tank, a water-dosing pump, and a steam chamber.
  • the water pump pumps water from the water tank to the steam chamber (as drips rather than a large flow of water) via a hose under command of a pump signal from an electric control device.
  • the rate at which water is supplied dictates the amount of steam being produced, and the amount of steam is sufficiently low that the temperature of the sole plate is not significantly affected.
  • water can be dosed to the steam chamber under gravity.
  • the steam chamber is typically heated by the soleplate comprising a heating element, but an auxiliary heating element may instead be provided.
  • the steam from the steam chamber reaches steam outlet opening or openings provided in the soleplate of the iron.
  • the steam ironing device may be a steam iron or a so-called boiler ironing system, comprising a steam iron and a boiler for heating water which is separately arranged from the steam iron, wherein the water tank is attached to a stand comprising the boiler.
  • the water tank is removably arranged, so that a user of the device comprising the water tank is capable of bringing the water tank to a tap or the like in order to fill the water tank, without having to move the entire device.
  • the method according to the invention of manufacturing a soleplate having a contact layer comprises the steps:
  • the substrate is preferably made from stainless steel or aluminium.
  • aluminium is mentioned in this application both aluminium and aluminium alloys are meant. Suitable choices are for example Aluminium 1100, Aluminium alloy 5052, Aluminium alloy 5754.
