Definitions

  • the present invention relates to a component made of non-woven natural textile fibres, and to a method and machine for the production thereof.
  • Textile fibres are subdivided into two broad categories: natural fibres and high-tech fibres; the natural fibres are in their turn subdivided into fibres of origin: vegetable (for example, lino, hemp, jute, coir, cotton, etc), animal (for example, silk, and wool of various animals such as the sheep, camel, etc), and mineral (for example, asbestos or glass fibres, etc) which, although natural in certain ways in that they are derived from minerals that are found in nature, are obtained only by means of necessary thermal and/or chemical processes.
  • vegetable for example, lino, hemp, jute, coir, cotton, etc
  • animal for example, silk, and wool of various animals such as the sheep, camel, etc
  • mineral for example, asbestos or glass fibres, etc
  • High-tech fibres are, for their part, usually subdivided into:
  • Synthetic fibres produced from synthetic polymers (for example, polyamide, polyethylene, polypropylene, etc), typically produced from petroleum.
  • Products made of textile fibres are used in various sectors of industry as well as, of course, in the textile industry; for example, as heat-insulating and/or sound- absorbent components in the construction industry, as upholstery components in the furniture and automobile industries, as filtering components for various applications, and in geotechnics.
  • the fibres are generally woven; in this way the product acquires density and durability; weaving is a known technology that has been used for millennia.
  • non-woven fabric technology
  • this technology uses “synthetic" fibres normally (frequently different ones mixed together), is more economical than weaving, and enables fairly elevated rates of production.
  • Components made from textile fibres are known, that are capable of performing functions of thermal insulation, acoustic isolation, padding, or filtering.
  • binding material for example, acrylic or styrolic resins, etc
  • aqueous solution which performs its function following a necessary heat treatment, in particular, both by evaporation of the water and by polymerisation of the said resin used.
  • this process very gradually began to be replaced by the insertion of bicomponent synthetic fibres into the fibre mixtures of the products, which synthetic fibres, on account of the ability of one of the two components to melt at low temperatures, bind very closely to the other fibres; in this case the binding effect is provided by the thermoplastic portion of the bicomponent fibres.
  • the binding material and the heat treatment thereof involve a fairly complex and expensive production process; to give an example, the heat treatment must not damage the primary material of the component and so jeopardise the quality of the finished product, its production requires special machinery, uses large amounts of energy (some of this energy is wasted because it goes to heat the primary material of the component and the surrounding environment), and emits carbon dioxide (CO2) and carbon monoxide (CO) into the atmosphere.
  • the heat treatment must not damage the primary material of the component and so jeopardise the quality of the finished product, its production requires special machinery, uses large amounts of energy (some of this energy is wasted because it goes to heat the primary material of the component and the surrounding environment), and emits carbon dioxide (CO2) and carbon monoxide (CO) into the atmosphere.
  • thermoplastic material renders components of this type not fully environmentally compatible, even in the case wherein the primary material is made of natural textile fibres (and therefore environmentally compatible); thus, even the waste of energy and the emission of carbon dioxide (CO2) and carbon monoxide (CO) into the atmosphere, that are due to the production process, contribute to the environmental non-compatibility.
  • CO2 carbon dioxide
  • CO carbon monoxide
  • the general object of the three present invention is to improve known components and known technologies by . providing a component having thermal insulation and/or acoustic isolation and/or padding and/or filtering functions made exclusively of environmentally compatible material or materials.
  • a first, more specific object of the present invention is to provide a component having thermal insulation and/or acoustic isolation and/or padding and/or filtering functions which does not require heat treatments for its production.
  • a second more specific object of the present invention is to provide a component having thermal insulation and/or acoustic isolation and/or padding and/or filtering functions that can be produced in an environmentally compatible manner.
  • a third more specific object of the present invention is to provide a component having thermal insulation and/or acoustic isolation and/or padding and/or filtering functions that is made exclusively of wool and produced in environmentally compatible manner.
  • the underlying idea of the present invention is that of producing the component starting from a web of natural textile fibres that is first "pleated” and then “needle- punched” in a direction corresponding to the length of the web; in particular, the needle-punching is performed in a direction transversal, preferably perpendicular to the thickness of the pleated web; in this way, the component has a certain density and structure, but also considerable elasticity, softness and lightness.
  • the component composed exclusively of non-woven natural textile fibres comprises a web of carded natural textile fibres which is pleated in the direction of the length and/or width of the component and which is needle-punched in the direction of the length and/or width of the component; the pleating gives a component thickness, and the needle-punching affects only a central portion of said thickness; this central portion is preferably less than 80% of the thickness of the pleated web (in particular 80% of the minimum thickness, in the case of variable thickness).
  • the needle-punching is preferably 4- 0 cm deep, more preferably 5-9 cm.
  • Said natural textile fibres may be all of wool.
  • Said natural textile fibres may be of two or more materials.
  • Said component may comprise exclusively a web of carded natural textile fibres.
  • Said direction of needle-punching may correspond to said direction of pleating.
  • the thickness of said component may be constant and correspond to the pleating dimension.
  • Said pleating dimension may have a value selected from between 4 mm and 40 mm.
  • the method for producing a component from non-woven textile fibres comprises the steps of:
  • the pleats of the pleating will be in a transversal direction, more particularly in a direction perpendicular to the length of said web.
  • Said pleating operations may be alternated by said needle-punching operations.
  • Each pleating operation may be immediately followed by a needle-punching operation.
  • Said pleating head may perform an alternating translating movement in a direction corresponding to the length of said web.
  • Said needle-punching head may perform an alternating translating movement in a direction corresponding to the length of said web.
  • Said needle-punching head may perform an alternating translating movement in a direction perpendicular to the thickness of said web after said web has been pleated.
  • the movement of said needle-punching head may be such as to complete preceding pleating operations.

  • Said needle-punching head may comprise a plurality of needle-punch needles with a length of 4-10 centimetres, preferably 5-9 centimetres.
  • Said needle-punching head may comprise a plurality of needle-punch needles, each equipped with lateral spikes preferably orientated as the needle itself.
  • a machine for producing a component made with non-woven textile fibres according to the present invention comprising:
  • a pleating head located in said processing area and adapted to repeatedly perform pleating operations on said web
  • a needle-punching head located in said processing area and adapted to repeatedly perform needle-punching operations on said pleated web, in such a way as to needle-punch only a central portion of a thickness of said component, said central portion being in particular less than 80% of said thickness, and

  • component 1 consisting exclusively of non-woven natural textile fibres according to the present invention is shown in Fig. 3.
  • This component derived from a web 2 of carded natural textile fibres, in particular of carded wool, shown in Fig. 1 in a horizontal position before the processing that is the subject of the present invention.
  • the web 2 has been pleated, as can be seen in Fig. 2, in a horizontal direction. Thereafter, the web 2 has been needle-punched, as can be seen in figure 3, in a horizontal direction.
  • the needle-punching operation performed with limited number of needles (in particular 1-9 per square centimetre) binds the web 2 in a horizontal direction even without any support material, in particular without the use of thread, and compacts the web a little in the horizontal direction; in this way, the component 1 exhibits a certain density and structure; however, because the number of needle-punch needles is limited, component 1 maintains considerable elasticity, softness and lightness similar to that of the web 2 from which it derives.
  • limited number of needles in particular 1-9 per square centimetre
  • the direction of needle-punching advantageously corresponds to the pleating direction, although this is not strictly essential for the present invention.
  • Component 1 consists of a sort of soft and pliable mattress of constant thickness S corresponding to the pleating dimension; this pleating dimension is 20 mm; this pleating dimension may alternatively have been selected from between 4 mm and 40 mm.
  • the possibility is not excluded of the component - in accordance with alternative embodiments - having a variable thickness (deriving from a variable pleating dimension) and constituting a profiled mattress.
  • the present invention also relates to a machine for producing a component of non- woven natural textile fibres such as that just described, or an analogous component.
  • Fig. 4 shows:
  • a needle-punching head 7 located in said processing area 5 and adapted to repeatedly perform needle-punching operations on said web 4 after it has been pleated , and
  • the web 4 is continuous, extends longitudinally from left to right, and moves progressively from left to right, passing through the processing area 5 while the processing is taking place.
  • the pleated and needle-punched web may be, for example, rolled to form a roll, or cut to form a plurality of squares.
  • the means 3 and 8 may be realised for example by means of conveyor belts.
  • the pleating head 6 is represented diagrammatically in Fig. 4 as a rectilinear bar adapted to bend the web.
  • the needle-punching head 7 is represented diagrammatically in Fig. 4 and Fig. 5 as a rectilinear bar 71 equipped with a plurality of (needle-punch) needles 72; needles 72 are of a length such as to pass through a plurality of layers of web 4 (indeed, according to the present invention, a preferred needle length of 4-10 cm and a yet more preferred needle length of 5-9 cm is provided for); in Fig. 5, the needles 72 pass through seven layers of web 4 and reach the eighth layer.
  • the conveyor belt 3 feeds the web 4 longitudinally towards the processing area 5 from left to right; the processing area 5 is located in a lower position (for example 5-20 cm lower) than the area of advancement of the web 4 defined by the conveyor belt 3.
  • the pleating head by moving first from high to low, from a pre-arranged higher position (Fig. 4) to a pre-arranged lower position, and then from low to high, from the pre-arranged lower position to the prearranged higher position (Fig. 4), the pleating head first of all creates a downward-pointing pleat in the web 4 and then an upwardly pointing web pleat; in this way a pleating operation is performed on the web 4 according to a direction corresponding to the length of the web itself, that is, the pleats are crosswise to the length of the web).
  • the pleating head by moving first from left to right, from a pre- arranged position distant from the web (Fig. 4) to a pre-arranged position adjacent to the web (Fig.
  • the needle-punching head 7 performs a needle-punching operation on the pleated web in a direction corresponding to the length of the web itself.
  • the conveyor belt 8 continuously feeds the web 4 from left to right after it has been pleated and needle-punched, while distancing from the processing area 5.
  • the pleating operations and the needle-punching operations are repeated; in particular, the pleating operations are alternated with the needle-punching operations; more particularly and advantageously each pleating operation is immediately followed by a needle-punching operation.
  • the pleating head 6 performs an alternating translating movement in a direction perpendicular to the web 4
  • the needle- punching head 7 performs an alternating translating movement in a direction longitudinal to the web 4 as it moves (direction D1 ) within the machine towards the processing area, and to that of the finished component as it moves (direction D2) within the machine via the processing area (be precise, the head 7 with its needles 72 operates on the web 4 in a direction perpendicular to the web 4, but after the web 4 been pleated, that is, pleated a plurality of times); specifically, the needle- punching head 7 is fashioned and moves in such a way as to complete preceding pleating operations, that is, when the one bar 71 of the head 7 moves towards the pre-arranged position adjacent to the web (Fig. 5), it drives it away a little and re- marks the pleats of the pleating.

Furthermore, as can be seen in Fig.
  • the arrangement of the needles 72 on the head 7 is such as to needle-punch only a central portion of the thickness of said component, that is of the thickness of the pleated web; in particular, this central portion is less than 80% of the thickness (in particular 80% of the minimum thickness, in case of variable thickness); in this way, the component presents a good density and durability, but its softness and its flexibility independently of its thickness are not sacrificed.
  • the needle-punching head 7 comprises a plurality of needle-punch needles 72, each equipped with a plurality of lateral spikes which allow the needle-punching effect of the needles themselves to be maximised; these spikes are disposed along the length of the needle; the spikes are orientated as the needle itself in such a way as to provide the needle- punching effect when the needle is inserted into the pleated web, but not when the needle is withdrawn from the pleated web.
