Benefits of technology

[0011]Thus, because of the particular technique used for fabricating the fabric and because of a suitable selection of components for use in fabricating a fabric, it is possible to obtain a protective patch that performs the same functions as those known in the state of the art in a single operation and without assembling different layers together. A fabrication process is thus obtained that is simpler, and above all a protective patch is obtained that is entirely suitable for being washed without any risk of delaminating.
[0033]Advantageously, the or each pocket is formed by fitting a panel onto the determined zone of the article, which panel presents great porosity, a certain amount of elasticity, and good dimensional stability. The pocket must not constitute a barrier to transferring the bodily secretion to the protective patch and it is necessary for said patch, particularly if it has a three-dimensional configuration, to be easily inserted into the pocket while also being held in place after it has been inserted and without stretching while being worn.

Problems solved by technology

If it is desired to regenerate such a protective patch after use by washing it by hand or in a machine, there is a major risk of the various layers becoming delaminated.
Furthermore, the assembly operations, whether by applying adhesive or by heat sealing, make the fabrication process more complex.

first embodiment

[0052]In the first embodiment, given in non-exclusive manner, the protective patch 1 consists of a fabric 2 that is said to be of the three-dimensional or 3D type in that it comprises two walls 3 and 6 that are both made of interlaced yarns, e.g., first warp yarns 4 and first weft yarns 5 for the first wall 3 and second warp yarns 7 and second weft yarns 8 for the second wall 6, said two walls 3 and 6 being connected together by a set 9 of link yarns, e.g., yarns 10 that, in the particularly simplified example shown in FIG. 1, pass in alternation over some of the first warp yarns 4 of the first wall 3 and under some of the second warp yarns 7 of the second wall 6. The technique for fabricating such a fabric of three-dimensional or 3D type is well known in the textile industry. It is possible to adjust the operating conditions of the loom used so as to determine accurately the distance between the two walls 3 and 6, which distance is occupied solely by the link yarns 10, and also so ...

second embodiment

[0064]Consequently, in the second embodiment shown in FIG. 2, the ptotective patch 11 also includes a breathable waterproof membrane 12 that is secured to the outside wall 6. Such a membrane 12 enhances the looked-for moisture barrier effect, while presenting sufficient porosity to allow air to circulate, which is useful for avoiding localized heating of the space between the patch and the wearer's body, which heating is likely in particular to accentuate perspiration. This porosity must also be sufficient to allow the moisture contained in the fabric 2 to be discharged in the form of water vapor, thereby correspondingly restoring its capacity to absorb moisture.

[0065]The technique for securing the breathable waterproof membrane 12 to the outside wall 6 must enable the membrane to retain its porosity. It is preferable to use dots of hot-melt type adhesive.

third embodiment

[0066]FIG. 3 shows a protective patch 13 that differs from the second by securing an outer layer 14 on the breathable waterproof membrane 12, e.g., a layer of non-woven or lightweight textile having an adhesive 15 on its outside face, which adhesive is protected by an anti-adhesive sheet 16.

[0067]In this third embodiment, the protective patch 13 may be put into place directly by the user. It suffices to remove the anti-adhesive sheet 16 and to press the adhesive 15 against the inside face of the armpit zone 21 of an article of clothing 28.

[0068]The use of the outer layer 14 in this third embodiment is justified by the risk of delamination that might occur between the breathable waterproof membrane 12 and the article of clothing 28 were the adhesive 15 to be applied directly to said membrane 12.

[0069]More generally, the presence of an outer layer 14 is justified whenever there is a risk of the membrane being degraded or delaminated, either during manufacture of the protective patch o...

Abstract

The protective patch providing protection against visible transfer of bodily secretion is for incorporating on the inside of an article of clothing in a determined zone thereof. It comprises a fabric having two faces formed by interlaced yarns and connected to each other. The outside face of the fabric acts at least in part as an impermeable outer layer for coming into contact with the article, and comprises yarns made of a synthetic material. The fabric has “storage” yarns made of an absorbent material suitable for storing moisture and being visible little or not at all in the outside face. The inside face of the fabric, i.e. its face that is to come closer to the wearer of the article, comprises yarns suitable for absorbing and / or transferring moisture towards the storage yarns.

Description

[0001]This is a 371 national phase application of PCT / FR2009 / 051218 filed 25 Jun. 2009, claiming priority to French Patent Application No. 0854237 filed 25 Jun. 2008, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to protecting an article of clothing against bodily secretions that might be emitted while the wearer is wearing the article. The invention relates more particularly to a protective patch for incorporating inside an article of clothing in a zone thereof that is to be in register with a zone of the user's body that is likely to emit bodily secretions.BACKGROUND OF THE INVENTION[0003]Attempts have been made for a very long time to provide protection against the negative effects of perspiration of the armpit, often manifested by disagreeable odors and, on the garment, by traces of moisture or indeed ring stains in the zone under the arm. To provide protection against odors, use is made of deodorants or anti...
