Definitions
- the present invention relates to a method for manufacturing a textile covering, as well as to such a textile covering, which may in particular be a floor covering, a wall covering or a covering mat of the passenger compartment of a vehicle. .
- the back of the velveteen is impregnated with an aqueous solution of latex. Then, the assembly is subjected to a drying which has the function of removing the water from this solution until the latex reticles, but which has the drawbacks of requiring important equipment and being expensive.
- the latex After drying, the latex forms bridges which bind the fibers of the web together, in the area below the loops.
- the latex is non-thermoplastic and its presence in the textile coating impairs the recycling of the latter.
- a latex solution has other disadvantages than that of requiring a drying phase. In particular, it is accompanied by a pollution of large quantities of water whose depollution requires a dedicated purification plant, which implies significant investments and maintenance costs.
- a textile coating by coating the underside of a fiber web with a coating which can be deposited in molten form to then solidify by cooling. This coating can also come from a powder or a hot melt film which is melted only after its deposit on the underside of the sheet. In one case as in the other, the coating on the underside of the web does not provide satisfactory mechanical properties, especially in terms of dimensional stability and abrasion resistance of the textile coating.
- the invention aims at least to simplify the manufacture of a textile coating, without this is accompanied by a degradation of some of the mechanical properties of the textile coating.
- this object is achieved by a method of manufacturing a textile coating from a web of fibers comprising a reverse side, a first region, a second region and a locus face, the first region being a cohesion zone where the fibers of the web integrate into a tight entanglement retaining these fibers and which is located on only a part of the thickness of the web, the second region extending over another part of the thickness of the web to said face location.
- This method comprises steps in which: a) by subjecting the web, of which at least one of the faces facing and a location, to an alternating electric field, with a hot-melt binder in powder form, this powder binder is introduced into the fiber web, so as to concentrating said binder at the first region, then c) melting the binder with heat input, and d) allowing or letting the binder.
- the alternating electric field concentrates the powdered binder in the cohesion zone. Indeed, it would have been expected that the alternating electric field disperses the binder powder over the entire thickness of the textile coating, to the extent that it is known, for example from the document WO 99/22920, that Similar alternating electric field could effectively be used to effect homogeneous impregnation of a fibrous layer with powder.
- the upper part of the coating that is to say the second region, is as free of binder as possible.
- the previously defined process does not use dissolution and no drying is required. It can be implemented by means of a significantly less significant installation and less expensive than a facility handling a latex solution.
- the method defined above has the further advantage of offering flexibility as to the amount of binder in the textile coating and the location of this binder.
- This location can be modified by changing the face where the binder is deposited in powder and / or by varying the proportion of this powder binder deposited on one of the face of the web, relative to the amount of binder in powder deposited on the other side of the sheet.
- the location of the binder inside the web also depends on the residence time of the web between the electrodes, setting parameters of the field created by these electrodes, the peculiarities of the powder and in particular its particle size, as well as the fibers of the web and the density of this web.
- the hot melt binder is more specifically a thermoplastic binder. It can also be otherwise.
- the hot melt binder may be a fusible binder at a first temperature and thermosetting at a second temperature above this first temperature.
- the hot melt binder may be a polyethylene, a polypropylene, a polyester, an epoxy resin or a mixture thereof.
- the fibers of the web are advantageously made of a polymer, such as polypropylene, polyester, polyamide or a mixture thereof. It may also be cellulosic fibers.
- the web may also comprise different kinds of mixed fibers.
- the process comprises a step in which: b) at least a portion of the binder powder, possibly present in the second region of the web, is removed by subjecting the surface face of this layer to a cleaning.
- the method comprises a step in which: b ') a portion of the powdery binder is removed by subjecting the reverse side of the web to cleaning, such as vacuum cleaning or by brushing.
- the powder binder is a mixture of powders of different chemical natures.
- the method comprises a step in which the back side is coated with a coating containing fillers.
- the invention also relates to a textile covering comprising a web which is made of fibers and which comprises a reverse side, a first region, a second region and a locus face, the first region being a cohesion zone where the fibers of the ply fit into a tight entanglement holding these fibers and which is located on only a portion of the thickness of the ply, the second region extending over another portion of the thickness of the ply, above said ply first region, up to said face-face, a hot-melt binder joining fibers of the web between them and concentrating in the first region which comprises a core and a surface area connecting this core to the reverse face of the web, the proportion of hot melt binder with respect to the fibers being lower in the superficial zone than in the heart.
- the hot melt binder is advantageous in that it can be melted again by further heating the textile coating, after which this coating can be compression formed between two forms.
- the textile coating results from the implementation of a method as defined above.
- FIG. 1 is a schematic view of a carpet-making installation according to the invention, by the implementation of a method also according to the invention
- Figure 2 is a schematic and partial view, in cross section, of a needled sheet from which the installation of Figure 1 provides carpets
- - Figure 3 is a view similar to Figure 2 and shows an intermediate state in which is the fibrous web of Figure 2 during its transformation into carpet in the installation of Figure 1
- FIG. 4 is a view similar to FIGS. 2 and 3, and shows the structure of a carpet according to the invention and produced by the installation of FIG. 1 from the needled sheet of FIG. POSSIBLE MANNER OF REALIZING THE INVENTION
- FIG. 1 shows a plant 1 for manufacturing textile coatings or carpets 2 from a velorized needled sheet 3, by implementing a method according to the invention.
- the web 3 is initially dry, that is to say not impregnated. It is composed of polymer fibers 4 which interlock and thus form a tight entanglement 5 located on only a part of the thickness 6 of the web 3.
- the entanglement 5 holds the fibers 4 and is in another part 7 of this thickness 6.
- the fibers 4 are generally independent of each other at this other part 7, where they form loops 9 and which extends to one of the two main faces 8A and 8B of the web 3, namely its face 8A intended to form the top or location of the belt 2, the face 8B being intended to form the bottom or back.
- the web 3 has loops 9 on the side of its face 8A, since it is a needled velvet ply.
- the web 3 may have a simple needling, that is to say, not be velvety.
- a roll 10 of web 3 is unwound towards an impregnating device 11, in the direction symbolized by the arrow F in FIG. 1.
- an impregnating device 11 Upstream of this impregnation device 11, a substance, consisting essentially of a hot-melt binder 12 in powder form and which may also contain one or more additives, in particular fluidifying additives, is sprinkled on one of the main faces 8A and 8B of the sheet 3.
- This binder 12 is made of a hot-melt material whose melting temperature is lower than that of the fibers 4. Its flow rate is determined by a dusting device 13 synchronized with the speed of progression of the sheet 3 in the direction F.
- the impregnation device 11 comprises two facing electrodes 14 and 15 that are generally plane and parallel to one another, between which the layer 3 carrying the binder 12 in powder passes. These electrodes 14 and 15 generate between them an alternating electric field to which the ply 3 and the binder powder 12 are subjected at the same time. This field makes penetrate the binder 12 in powder in the thickness of the sheet 3, including in It has also been found that, surprisingly, the alternating electric field produced between the electrodes 14 and 15 concentrates the binder 12 in powder form at the level of this entanglement 5 so that, at the level of the part 7 of the tablecloth 3, the fibers 4 contain practically no powder binder 12, which is desired.
- the electrodes are flat and parallel to each other. However, in some cases, it may be advantageous to use electrodes having another shape and / or not parallel to each other. These electrodes may especially be like those described in document WO 2005/038123.
- an aspirator 16 subjects the face 8A to suction, that is to say to a cleaning intended to remove any binder grains 12 found in the part 7 of the sheet 3. This suction can be removed by being replaced or not by brushing.
- the structure of the web 3 directly after the vacuum cleaner 16 is visible in FIG. 3, where it can be seen that the binder 12 in powder is essentially concentrated at the level of the entanglement 5.
- a hot air oven 17 Downstream of the vacuum cleaner 16 is a hot air oven 17, in which a supply of heat melts the binder 12. Following this, the sheet 3 passes between two pressure rollers 20.
- the sheet 3 is subjected to a jet of cooling air 21 that one or more nozzles 22 expel and which causes the solidification of the binder 12. Also, the rollers 20 can be cooled and participate in the solidification of the binder 12. They can even cause this solidification without the presence of the cooling jet 21. It is also possible to allow the cooling of the binder 12 alone.
- the web 3 After solidification of the binder 12, the web 3 forms a textile coating, which is cut into several mats 2 by a knife 23 in the example shown.
- FIG. 4 The structure of a carpet 2 is visible in FIG. 4, where it can be seen that very little or no binder 12 is at the level of the loops 9. Bonding bridges 12 unite the fibers 4 to each other at the level of the entanglement 5 and, in doing so, secure the loops 9 to the remainder of the carpet 2.
- the proportion by weight of binder 12 with respect to the fibers 4 varies in the direction of the thickness, at the level of the 5. More specifically, this proportion is greater at a heart of the entanglement than at a superficial zone 26 bordering the heart 25 opposite the portion 7 and defines the lower face 8B of the carpet 2.
- the small proportion of binder 12 in the superficial zone 26 is visually observed on the lower face 8B. It can also be verified by measurements. These measurements can be based on a comparison by thermal analysis of the enthalpy of fusion of the fibers 4 alone and the enthalpy of fusion of the sample to be evaluated, for a fusion only of the fibers 4 present in this sample, to the Excluding its binder 12. From this comparison, we deduce the proportion by mass of fibers 4 in the sample and therefore that of binder 12.
- the sample is prepared by sanding performed so as to leave only what must be measured and remove the rest. For example, the sample prepared for measuring the amount of binder 12 in the surface area 26 results from sanding removal of the portion 7 and the core 25.
- a hot melt binder 12 compatible with the carpet fibers can be selected so that the carpet 2 can be recycled.
- the sheet 3 is a needled velor product having a basis weight of 600g / m 2 and a thickness of about 6mm. It consists of a mixture of fibers 4 of 6.5 dtex, 17 dtex and 150 dtex, made of polypropylene and initially devoid of any binder.
- the binder 12 is high density polyethylene, which is sprinkled at a rate of 90 g / m 2 on the web 3. Prior to its incorporation into this web, it is in the form of a powder having a particle size of 0 ⁇ m to 80 ⁇ m and sold by the company ABIFOR (Wutôschingen - GERMANY) under the reference 1300/20.
- the impregnation of the sheet 3 by the powder binder 12 takes place in the device 11 provided with electrodes 14 and 15 flat.
- the alternating electric field produced between these electrodes 14 and 15 has a value of 2 kV / mm and a frequency of 50 Hz.
- the sheet 3 provided with the binder 12 in powder form is subjected for 20 s to the alternating electric field. It then stays longer than 2 minutes in the oven 17 set at a temperature above the melting temperature of the binder and below the melting temperature of the fibers.
- a carpet 2 obtained according to this example 1 was subjected to the Lisson test as defined by the EN 1963 standard of the year 1997. After this test, a determination by visual evaluation of the level of defibration of the carpet 2 was carried out and gave a value of 3/5 in the machine direction, that is to say in the direction of arrow F in FIG. 1, and a value of 3/5 in the transverse direction, that is to say in the perpendicular direction in the machine sense.
- the carpet 2 had an average thickness of 6 mm.
- the proportion of binder 12 throughout its thickness was evaluated at 29.5% by weight by the method mentioned above and involving measurements of fusion enthalpy.
- the proportion of binder 12 in the last millimeter before the face 8B, that is to say on the back of the belt 2, globally at its surface area 26, was evaluated at 16.9% by mass by the same method. It can be deduced that the proportion of binder 12 in the surface zone 26 is less than that in the core 25. This is similar to the measurements made on a second carpet, made from the same web but by implementing the method of the prior art, that is to say using a latex solution.
- the proportion of latex throughout the thickness of this second carpet was evaluated at 26.7% by mass by the method mentioned above and involving measurements. of fusion enthalpy.
- Example 1 the same sheet 3 and the same binder 12 as in Example 1.
- This binder 12 is sprinkled at a rate of 120 g / m on the web 3.
- the impregnation of the sheet 3 by the powder binder 12 takes place in the device 11 provided with electrodes 14 and 15 flat.
- the alternating electric field produced between these electrodes 14 and 15 has a value of 2 kV / mm and a frequency of 50 Hz.
- the sheet 3 provided with the binder 12 in powder form is subjected for 20 s to the alternating electric field. It then stays longer than 2 minutes in the oven 17 set at a temperature above the melting temperature of the binder and below the melting temperature of the fibers.
- a carpet 2 obtained according to this example 3 was subjected to the Lisson test as defined by the EN 1963 standard of the year 1997.
