Definitions

  • the invention relates to a waterproof fitted sheet, its manufacturing process for waterproofing it and a device for implementing said process.
  • the invention will very particularly find its application in the field of bedding and in particular for covering and protecting mattresses for children or adults and for incontinence.
  • fitted sheets have a central tray intended to cover the upper face of the mattress, this tray is surrounded by a rim which covers the edge of the mattress, this rim is provided on its periphery with an elastic band to keep the fitted sheet applied. on the mattress.
  • This type of fitted sheet can be made in a single piece of fabric or possibly in several pieces of fabric which are then attached and sewn together.
  • the waterproof zone is produced by applying a plastic film on a piece of fabric of substantially the same size, then the assembly is sewn onto a piece of complementary fabric to form the fitted sheet.
  • the plastic film is deposited in a strip on a piece of fabric, by calendering. This provides a continuous manufacturing process for waterproofing a fabric. Then, the roll of waterproof fabric obtained is cut into waterproof pieces which are sewn to make the fitted sheet.
  • the width of the plastic film is less than that of the fabric, it is possible to obtain a certain homogeneity of the waterproofing in the transverse direction since there is no discontinuity between the two lateral strips of fabric and the central part which receives the plastic film. But later, in the longitudinal direction, there will be a seam which will remove the homogeneity which had been obtained initially.
  • the main object of the present invention is to provide a waterproof fitted sheet which has perfect homogeneity of its fabric over the entire periphery of the waterproofed area.
  • the fitted sheet thus has no seams at this level which makes it particularly comfortable and resistant.
  • Another object of the present invention is to present a waterproof fitted sheet, made of an extensible fabric, and which provides substantial savings in terms of its production, in particular by saving the area of the piece of fabric used for making.
  • Another object of the present invention is to present a manufacturing method for waterproofing the fitted sheet by hot application of a plastic film by which the risks of air bubbles forming when welding the film on the fabric are eliminated.
  • the waterproof fitted sheet intended in particular to cover and protect a bedding mattress or in the field of incontinence, comprising in particular a central tray in fabric waterproofed by a plastic film surrounded by a flange having on its periphery elastic means or at least retractable is characterized in that it has a homogeneity of the fabric on the periphery of the waterproofed area.
  • the manufacturing process for waterproofing a fitted sheet, the underside of which is intended to be applied to a bedding mattress is characterized in that a piece of plastic film cut to the dimensions of the desired waterproof area is applied. , by hot pressing on the back of the fitted sheet in the area of the tray to be waterproofed and that simultaneously with pressing, the air present in the fabric is removed.
  • the device for implementing the process for waterproofing the fitted sheet is characterized in that it is in the form of a re cac the support on which is placed the bottom sheet to be waterproofed tense.
  • Figure 1 shows a waterproof fitted sheet that has been developed to observe the different parts that constitute it.
  • This fitted sheet 1 is made of fabric, this term to be taken in the broad sense and includes all the achievements of textile surfaces such as in particular jersey, knitting, etc.
  • the fitted sheet has a central plate 2 which is intended to cover the upper face of the bedding mattress, this tray 2 is surrounded by a rim 3.
  • This rim 3 can be a piece of fabric attached to the central tray 2, but in general it will have perfect continuity with this tray 2 being produced in the same piece of fabric.
  • the rim 3 is intended to cover the edges of the bedding mattress, this rim 3 is bordered externally by elastic or at least retractable means in order to apply the fitted sheet to the mattress to be covered.
  • the plate 2 will present an impermeable zone 4.
  • this impermeable zone 4 will have perfect homogeneity with the whole of the plate 2, that is to say that it will have no seams on its periphery.
  • the waterproof area will be composed by a plastic film applied to fabric.
  • the piece of fabric on which the plasticized film is applied will be identical to the piece of fabric making up the rest of the tray 2.
  • the tray 2 will be made up by a single piece of fabric, the impermeable zone 4 being obtained by application of a plastic film on said piece of fabric.
  • the fabric that makes up the tray 2 will preferably be in the stretched state.
  • the plastic film which is welded to the fabric makes it possible to immobilize the fibers making up the fabric in a certain state.
  • the plastic film will immobilize the texture of the fabric so that, for example, in the case of knitting, the stitches are stretched.
  • the plastic film will of course allow the folding of the sheet but on a small scale, the plastic film will impose a tension on the fibers of the fabric.
  • a stretch fabric will be used to make the tray 2.
  • the plastic film will cover an area of fabric in the stretched state. This stretching will not however be exaggerated beyond measure in order not to cause a distension of the fabric and furthermore it is necessary that the fabric nevertheless forms a structure for the plastic film.
  • the waterproofed zone which has a plastic film placed on a stretched fabric allows a saving of material at the level of the fabric surface used. Since, in this case, the surface of the waterproofed area is made with stretched fabric and therefore larger than the originally unstretched piece of fabric.
  • the plastic film is preferably applied to the back of the fitted sheet, this is ie the side of the fitted sheet that will be applied against the bedding mattress.
  • the fitted sheet will present greater comfort since it will present externally only a piece of fabric.
  • the plastic film piece will appliq L ed on the bottom sheet of fabric already achieved.
  • the piece of plastic film will be cut to the dimensions of the desired waterproof area, then the piece of plastic film will be applied by hot pressing on the back of the fitted sheet in the area of the tray to be waterproofed, which will allow the plastic film to be held on the fabric by welding.
  • the fabric making up the fitted sheet will be tensioned, at least in the zone to be waterproofed, prior to the application of the plasticized film.
  • this will make it possible to artificially increase the dimensions of the fitted sheet.
  • the plastic film will be applied on a stretched fabric surface and will immobilize the texture of the fabric in this position by welding. This will allow a substantial gain by saving the area of fabric on which the piece of plastic film will be applied.
  • Figure 2 shows schematically a device for implementing the method of the invention. It is more particularly a support mattress 5 on which will be fitted the fitted sheet to be waterproofed.
  • This support mattress 5 has dimensions similar to those of the bedding mattress for which the fitted sheet is intended or preferably smaller.
  • the support mattress 5 will have particular properties and in particular a possibility of expansion as illustrated by the arrows 6. In this way, after having put the fitted sheet on the support 5, the latter will be expanded which will have for consequence of placing the fitted sheet under tension.
  • FIG. 2 an expansion in two directions of the transverse plane has been shown diagrammatically, but an expansion in one direction could have been envisaged.
  • the plastic film is applied to the fabric of the stretched fitted sheet, which provides the advantages described above.
  • the support mattress After application of the plastic film and when it has cooled, the support mattress is retracted again and the fitted sheet is released.
  • the waterproofed fitted sheet obtained is larger than the originally fitted sheet.
  • the support mattress it will present on its surface at least in the zone in contact with the zone of the waterproof fitted sheet, means for absorbing or evacuating the air.
  • the air contained in the fabric can be evacuated.
  • Figure 3 shows schematically a preferred embodiment of these means.
  • the frame 7 of the support mattress will present on its surface a cushion 8 made of cellular material.
  • the air present in the piece of fabric 10 can penetrate into the cellular material 8 and flow through the alveoli to the outside.
  • the foam material may advantageously be foam resistant of course to the temperature.
  • this device comprises a tubular frame of substantially rectangular shape with the dimensions of a traditional bedding mattress.
  • the fitted sheet is placed on the frame of the device. To do this, simply wrap the frame with the fitted sheet, the border of which folds around the frame, remaining in this position using the peripheral elastic. It should be noted that the fitted sheet being placed on a frame whose dimensions are substantially the same as those of a traditional bedding mattress, the fitted sheet will be placed on the frame in the stretched state.
  • This cushion will preferably be made of a cellular material such as foam. Then, we have the plastic film on the fitted sheet stretched over the frame where we want to waterproof this fitted sheet.
  • the hot plate of the press can be released and the fitted sheet can be removed from the frame, this fitted sheet is then waterproofed.
  • the plastic film may be a PVC with a thickness of about 20/100 mm which will be applied at a temperature between 100 and 200 degrees, preferably of the order of 200 degrees.
  • the force of application of the plastic part will be limited to 6 kg so that the plastic film nevertheless remains superficial on the piece of fabric and does not penetrate it too deeply.
