Definitions

  • the present invention relates to a process for the manufacture of a textile flooring material, in particular a recyclable wall-to-wall carpeting.
  • the invention further relates to the textile flooring material manufactured according to said process. More specifically, the invention relates to those textile flooring materials that are subject to an intensive use over a short period of time, for instance during a fair show, and are destined to be removed after use.
  • textile flooring materials for these types of use are manufactured using synthetic materials, essentially for their cost-effectiveness, and include a needlepunched base layer made of a synthetic fiber, mainly polyolefine fiber and in particular polypropilene fiber, held together by a layer of binding resin applied onto a face thereof.
  • binding resin an aqueous solution (latex) of a styrene-butadiene copolymer is used as binding resin.
  • the solution contains various additives and fillers, e.g., calcium carbonate and aluminium hydroxide, in order to increase its consistence and fire retardant properties, thickening agents for controlling its fluidity, etc.
  • the latex can be applied with a spreader roller drafting from a latex collection tank, or with another likewise technique, and then the latex-saturated semifinished product is heated in order to evaporate the water and dry the binder.
  • the fitting of this type of carpet is implemented by means of a two-sided tape, that also enables an easy removal of the carpet after use.
  • An object of the present invention is to provide a process for the manufacture of a textile flooring material which is able to be recycled after use by means of a treatment that entails no damage to the fiber, thus allowing the reclaiming of at least the latter and the reintroduction thereof into the manufacture cycle.
  • a particular object of the present invention is to provide an after-use recyclable carpet.
  • the process according to the invention is conventionally based on the use of synthetic fibers received as bales that undergo a preliminary treatment indicated with 1, i.e., a processing through a machine 2 called "bale-breaker" for homogenising the batch by grading it according to the colour and to the fiber type (denier, length, crimp, composition).
  • a first rough opening of the fiber staples, compacted by the stationing thereof inside the bales, is implemented in a carding willow 3, and then lubricating oil is added to the partly-opened fibers to let them slide into a so-called oiling cell 4.
  • the fiber compound thus obtained, or “mix” is then sent to the next manufacture step of a raw fiber panel, or felt, indicated with 5. At this stage, the fiber compound is repeatedly aired inside storage chambers 6 to which it is recirculated with a suitable device called "mill” 7.
  • the compound thus homogenised is sent to a carding machine 8 comprising: a feeder 9 receiving the fiber from chambers 6 and laying it homogeneously, in the shape of a mat on the conveyor of the apparatus: a carding machine 10 formed by a series of toothed cylinders of various diameters providing the fiber paralleling and the laying of the same onto a conveyor belt as a light and homogeneous card web: a lap roller 11 receives the card web and lays it as a multilayer onto a conveyor belt that feeds a needlepunching apparatus 12.
  • Needlepunching is carried out in a series of knitters which, by means of the action of a plurality of needles, moving orthogonally to the fiber mat feed in a reciprocating swift motion, that seize the fibers and drag it through the fiber mass, binding and compacting therebetween.
  • the semifinished product resembles a felt and is sent to the subsequent finishing process.
  • a binder in a aqueous suspension contained in a collection tank 13 is applied onto the back of the felt with a spreader roller 14 drafting therefrom.
  • the binder-saturated felt is passed through a hot air circulation drying apparatus 15 wherein layer water is removed by evaporation, yielding a flexible layer strengthened onto the back of the felt.
  • the finished product is delivered to a packaging unit 16.
  • the binder is a water-resistant vinyl resin having hydrolizable functionalities sufficient to be dissolved in a strongly basic solution when heated.
  • a vinyl resin having such qualities comprises a vinyl acetate homopolymer or a copolymer of vinyl acetate with at least one of the following compounds:
  • the aqueous suspension of the binder, or binding bath, contained in the collection tank 13 and applied onto the felt back, in a practical embodiment consists of an inert filler made of aluminium hydroxide or calcium carbonate, a thickening agent and water.
  • the average percent composition by weight of the binding bath is the following: vinyl resin 20-40% inert filler 40-70% thickening agents 1- 5% water 5-35%
  • a plastifier is further provided, preferably a molecular phtalic, isophtalic, benzoic or phosphoric plastifier, e.g. a dimethylphtalate or the like.
  • the plastifier can constitute from 0 to 40% of the binding bath, depending on the product softness required.
  • the binding resin is the commercial product VINAVIL 19 WM, and the inert filler is aluminium hydroxide, 27% and 54% b/w respectively.
  • the inert filler is aluminium hydroxide, 27% and 54% b/w respectively.
  • a fire-retardant product is obtained.
  • calcium carbonate can be used when fire retardant properties are not a prerequisite.
  • the binder density is regulated in order to have an applied quantity comprised from 400 to 1000 g/m 2 (wet basis).
  • the carpet manufactured with the process according to the invention is made of a layer of needlepunche non-woven fabric of a synthetic fiber, and of a layer of a resinous binder applied onto a face thereof.
  • the binder layer can be entirely dissolved in a strongly basic solution, e.g. a 5-30% NaOH solution, a property that is advantageously exploited in the reclaiming process of the used carpet, as is described in a corresponding patent application filed on the same date by the same applicant.
  • the carpet according to the invention is first separated from possible two-sided tape and coarse dust residues, and then is scoured with a strongly basic solution, e.g., with a 15% NaOH caustic bath. Under such conditions the binder layer is completely dissolved and the fiber can be reclaimed and recycled.
  • the solution containing the binder and the inert filler in suspension can be reclaimed as well by acidification with a separation of the water that can be returned to the process water circuit, and of a precipitate made of the binder admixed to the filler that can be reused to form binders for other covering materials.
  • the preferred synthetic fiber type is polypropylene, both for the cost-effectiveness and for the hydrophobic, acid- and light-resistance characteristics thereof.
  • a certain percentage of fire-retardant modacrylic and/or polyester fiber can be advantageously added thereto, in a ratio comprised from 10 to 50%.
  • the final unit weight of the product is comprised from about 400 to 900 g/m 2 .
