Definitions

  • the subject invention relates to an inner sole and insole construction for shoes, boots and other footwear.
  • the subject invention represents an improvement over the loose inner soles and insoles of textile materials which are commercially available today.
  • the sole in accordance with the invention comprises at least three layers of which at least one of the outer layers consists of a textile material and the characteristic features of the sole construction in accordance with the invention are that one inner layer consists of a batt of predominantly peat material which peat layer is surrounded on either side by at least one layer of a different material.
  • at least one of the at least two layers surrounding the peat layer comprises predominantly synthetic fibres. Woollen fibres may be included in at least one of the sandwiching layers.
  • the peat layer comprises comparatively short peat fibres or peat fibres of medium length which may also include bonding elements of some kind.
  • the bonding elements could be thermoplastic low-melt fibres or granules which melt or soften when heat treated and thus bond the peat fibres together.
  • the sole material comprises three layers, viz. one upper layer 1 of predominantly woollen fibres, a middle layer 2 consisting predominantly of peat fibres and a bottom layer 3 consisting predominantly of one or several synthetic fibre materials.
  • the three layers are interconnected in a conventional manner, preferably by means of needling.
  • the bottom layer 3 may be stabilized in a heat treatment operation causing the fibres to fuse together.
  • the upper layer 1 as well as the peat layer 2 may include fibres or other materials having a lower melting point so that when exposed to a heat treatment they will serve as bonding elements within their respective layer.
  • the woollen fibres in the upper layer 1 may be replaced by synthetic fibres.
  • the various layers and primarily the outer Tayers 1 and 3 may be made from mixtures of different fibre materials.
  • the intermediate or centre layer 2 consists of peat fibres of various lengths.
  • the fibres Preferably, the fibres have a length ensuring that the layer becomes dust-proof.
  • the peat fibres to be used in the soles are obtained by drying peat, whereafter the fibres included in the peat are separated in a separator in a cyclone process.
  • the peat making up layer 2 imparts a number of advantageous properties to the sole in accordance with the invention.
  • the peat layer 2 absorbs moisture to a larger extent than most other fibres. This means that the peat layer 2 will absorb perspiration.
  • the peat also have bactericide properties and consequently it will prevent the generation of unpleasant perspiration odours. To a large extent the peat operates by binding and neutralizing perspiration, salts, etcetera which contributes to a pleasant climate inside the shoe. When used as a loose inner sole it keeps the foot at a pleasant and comfortable temperature and increases the air circulation inside the shoe.
  • the peat layer together with a top layer consisting of wool gives the sole excellent heat insulating properties.
  • a top layer consisting of wool gives the sole excellent heat insulating properties.
  • the material of the bottom layer good shape permanency and stability is imparted to the sole. Additionally, the sole becomes washable.
  • the porous structure of the sole allows the foot to breathe.
  • the manufacture of the sole in accordance with the invention is performed by needling the three layers 1, 2, and 3 together in a manner known per se so that long webs of material are formed from which the soles may be punched.
  • the shape permanency is achieved by treating the layer 3 with hot air.
  • the sole is suitable for use both as a separate inner sole and as an insole for a number of different footwear products.
  • Additional layers may be attached to the layers 1, 3, sandwiching the peat layer 2.
  • Such additional layer or layers may be made from a textile material but also other materials may be used, such as e.g. various types of foil.
