Definitions

  • nonwoven structures can be classified into three main categories, resulting from their very manufacturing process, to know the so-called “dry” nonwovens formed by carding and / or ventilation, the latter technique being commonly designated by the expression “Airlaid technique”, nonwovens obtained by "melted” technique commonly referred to as “spunbond”, and the technique known as “by wet ”, derived from papermaking techniques.
  • the invention relates to a new method for making such a type non-woven article made from a mixture of fibers of a different nature which, in the rest of the description will be denoted by the expression “mixed nonwoven” or “Composite nonwoven”.
  • the cellulose fibers used in the production of the complex are wood fibers and their deposition is carried out by pneumatic coating.
  • the complex formed is preferably subjected to two treatments successive acting against the two opposite sides of the complex.
  • the invention also relates to a new type of nonwoven product obtained. by implementing this process.
  • Such a mixed nonwoven which therefore consists of a mixture of fibers different nature, characterized in that it consists of a layer of fibers natural, wood in particular, trapped between two nonwoven tablecloths formed of filaments, extruded and drawn, based on synthetic material, the cohesion of different layers being obtained by entanglement through the action of water jets.
  • this first veil (2) can be compacted by means of a pressing cylinder or by the action of jets from a ramp of hydraulic injectors.
  • the continuous filaments of this first veil (2) can be based on a polymer made of polypropylene, polyester or other materials synthetics such as polyethylene, polyamide, this list not being exhaustive.
  • the continuous filaments may possibly consist of so-called filaments "Bicomponent", such as those obtained by coextrusion of polypropylene and polyethylene.
  • the web of unbound continuous filaments (2) is then transferred under a unit, designated by the general reference (4), which, by air flow, allows deposit on the surface of the first sheet (2) staple fibers (4), of a other nature, and more particularly cellulose fibers, wood in particular.
  • the cellulosic fibers are deposited on the surface of the first veil (2) by through a draft.
  • the veil of filaments (2) is maintained on the conveyor belt (3) by means of a suction (5). Therefore, under the effect of the suction, said fibers (4) are preferably deposited between the unbound filaments of the web (2), thus allowing excellent integration of the two components.
  • the complex (2,4) which is still maintained supported by the conveyor belt (3), is then brought below a second formation zone (6) of a second veil of continuous filaments (7), also synthetic, of the same kind or of different in nature than those of the first veil (2).
  • a pressure roller (8) is preferably placed after this deposition zone of the web (7), and makes it possible to ensure compaction of the assembly with a view to its transfer to the hydroliage installation, designated by the general reference (9), which follows the production line.
  • this compacting operation could be carried out at by means of a ramp of hydraulic injectors.
  • the complex is then introduced into the hydroliage zone (9) on a conveyor (10) on which are successively carried out the operations of compacting and pre-wetting of the assembly by means of a conveyor upper (11) tangent to the lower conveyor (10), and inside which is arranged a hydraulic injector (12).
  • the complex After compacting and pre-wetting, the complex is subjected to the action of a succession of water jets (13) delivered by several hydraulic injectors arranged in series.
  • the structure thus treated is then transferred, by inversion, to a cylinder (14), or on another conveyor, associated with several injectors (15) which also deliver water jets on the other side of the complex, thus strengthening the consolidation of all layers, while providing good resistance to abrasion of the layer located opposite the jets.
  • the complex thus obtained is then transferred to an expressing conveyor (16) on which it is expressed using a suction box connected to a generator empty.
  • a product according to the invention is produced in the following manner.
  • a continuous veil of filaments (2), weighing 15 g / m 2 is produced on an installation marketed by the Applicant under the name "spunjet", which makes it possible to produce a nonwoven web by extrusion, drawing and distribution of continuous filaments.
  • polypropylene such as that sold by the company AMOCO under the reference 100 ZA 35.
  • the veil formed consists of 7000 filaments per meter of width and is produced at a speed of 250 meters per minute.
  • the diameter of the filaments after stretching is about 15 microns.
  • a suction located opposite the stretching slot (20) makes it possible to control precisely the deposit of the filament and its regularity on the conveyor belt (3).
  • Such a fiber distribution assembly can consist of a conventional installation such as that sold by M & J.
  • cellulose fibers and more particularly wood fibers, sold by the company Korsnaes, are deposited on the veil of continuous filaments (2), these wood fibers, with a length of of the order of 3 mm, being commonly designated by the expression "fluff paste”.
  • a suction box (5) is placed under the conveyor under the entire surface of the distribution air head (4).
  • This suction head (5) is connected to a vacuum generator that distributes the wood fibers evenly while preserving the homogeneity of the veil of continuous filaments (2).
  • a pressure roller (not shown), the speed of which is synchronized with said mat (3) compacts the assembly thus formed.
  • a second veil of continuous filaments weighing 15 g / m 2 is deposited on the surface of the complex , of the same nature as the first veil (2).
  • This veil can be formed either on the same conveyor (3), or on a independent conveyor.
  • This veil (7) is therefore distributed over the layer of cellulosic fibers (4).
  • the transfer is carried out in a positive way using a case suction (5a) arranged under the main conveyor opposite the transfer point.
  • the structure obtained which weighs 65 g / m2, is possibly compacted at by means of a cylinder (8). This compaction can possibly be carried out at by means of an additional ramp of hydraulic injectors.
  • the complex is then transferred to the conveyor (10) of the binding unit hydraulic (9).
  • Such a binding unit comprises a main conveyor (10) above of which an upper conveyor (11) is disposed, tangent thereto, and inside which is arranged a hydraulic injector (12), delivering 4000 water jets by meter, these jets having a diameter of 130 microns and a speed of 34 meters per second.
  • the “sandwich” thus compacted and wet is treated on its upper face by six hydraulic injectors (13), arranged in series which project water jets of 120 microns in diameter spaced 0.6mm apart at speeds respectively 110, 125, 140, 140, 140,140 m / second.
  • the treated complex is then transferred by inversion to a cylinder (14) around which are arranged four hydraulic injectors (15) which project 120 micron diameter water jets spaced 0.6mm apart from each other respective speeds of 125, 140, 140, 140 m / second.
  • the complex thus consolidated is transferred to an expressing conveyor (16) on which it is expressed by a suction box in which there is a vacuum of 400 mbar.
  • the product obtained weighs about 60 g / m 2 , has excellent homogeneity, good feel, great flexibility and excellent abrasion resistance both in the dry state and in the dry state. 'in the wet state.
  • Such a water absorption capacity is comparable to mixed nonwovens made up of staple fibers and which have been produced by carding.
  • Such a product is perfectly suited to various applications, such as industrial or household wiping products, impregnated wipes, gowns and operating theater fields, such applications being given as an indication but not limiting.
