Abstract

The invention relates to a three-dimensional fabric (1) produced by knitting for the production of a garment, referred to as a slash-resistant garment (10), the three-dimensional fabric comprising at least: - a first upper layer (2) knitted from a first yarn (3); - a second lower layer (4) knitted from a second yarn (5) of a different nature from the first yarn (3), the second yarn (5) imparting slash resistance properties to the lower layer (4) that are higher than those of the upper layer (2); - a third yarn (6) connecting the upper layer and the lower layer, the fabric being characterised in that the second yarn (5) is formed by combining at least two other yarns (7, 8) and is single jersey knitted to form the lower layer (4), the lower layer being intended to form an inner side of the attack-resistant garment on the side of the skin of a person wearing the garment.

Claims (11)

  1. [Claim 1] Three-dimensional fabric (1) produced by knitting for the production of a garment (10) known as anti-laceration, comprising at least: - a first outer layer (2) called upper knitted from a first thread (3), - a second outer layer (4) called the lower layer knitted from a second yarn (5) of a different nature from the first yarn (3), said second yarn (5) conferring laceration resistance properties on the lower layer (4) which are greater than those of the upper layer (2), - a third thread (6) connecting the upper layer and the lower layer, the fabric (1) being characterized in that the second thread (5) is formed by assembling at least two other threads (7, 8) and is knitted in single jersey to form the lower layer (4), said lower layer being intended to form an inner side of said anti-aggression garment, on the skin side of a person wearing said garment.
  2. [Claim 2] Fabric (1) according to claim 1, in which the second yarn (5) comprises a determined maximum count corresponding to the sum of the counts of the at least two yarns (7,8) assembled to form it, said maximum count being between 330 and 660 Dtex.

  5. [Claim 5] Fabric (1) according to any one of the preceding claims, in which the second thread (5) is produced by assembling at least identical threads (7,8).
  6. [Claim 6] Fabric (1) according to any one of the preceding claims, in which the second thread (5) is made of polyethylene optimized to resist laceration.
  7. [Claim 7] Fabric (1) according to any one of the preceding claims, in which the first yarn (3) is made of natural fibers.
  8. [Claim 8] Fabric (1) according to any one of the preceding claims, in which the connecting thread (6) is of the same nature as the second thread (5).
  9. [Claim 9] Garment (10) made from the fabric (1) according to any one of the preceding claims, in which the second layer (4) constitutes the reverse side of said garment (10), intended to be turned towards the skin side of a person wearing said garment (10).
  10. [Claim 10] Anti-aggression equipment (100) comprising a garment (10) according to claim 9 and an anti-ballistic device called a pack (20), the equipment (100) comprising a removable attachment system (101, 102) between the garment (10) and the pack (20).
  11. [Claim 11] A method of knitting a fabric (1) according to any one of claims 1 to 8, comprising: - A step of simultaneous knitting of the upper layer (2) and the lower layer (4) connected by the third thread (6), in which the first thread (3) is passed over a front bed, the second thread (5) is passed over a rear bed, and the third thread (6) passes successively from the front bed to the rear bed, and in which a bridge between the front bed and the rear bed is made between each stitch; - A washing step in a bath.

Description

DESCRIPTION Title: Three-dimensional fabric made by knitting, garment made from such a fabric, equipment comprising such a garment and method of knitting such a fabric FIELD OF THE INVENTION [01] The present invention relates to the field of physical protection equipment such as that which may be worn by users exposed to bodily attacks. [02] More specifically, the invention relates to a fabric for making a garment with a protective function against physical attacks, in particular attacks using a sharp weapon. TECHNOLOGICAL BACKGROUND [03] In order to ensure optimum protection, protective clothing should preferably be easy to wear, i.e. easy to put on and take off, and also light, i.e. it limits little, if at all, the movements of the person wearing it. [04] The fabric from which the garment is made may be: A fabric: that is to say a mesh formed by one or more weft threads which interweave one or more warp threads; A knit: that is to say a set of loops made in one or more threads which are passed through each other. [05] It is therefore known to manufacture protective clothing that resembles classic, everyday clothing: a T-shirt, a jacket, trousers, etc. Such protective clothing is made from a fabric providing a protective function. The function is chosen according to the type of protection to be provided. [06] In order to provide the protective function, the fabric is made from one or more so-called technical yarns, i.e. yarns that have particular properties. In general, such a fabric provides limited comfort: it is rougher, more rigid, so that direct contact with a user's skin is prohibited because irritation could occur. Thus, it is known to form with this fabric a protective garment that is worn over more classic, more comfortable clothing, and to avoid any direct contact with the skin. [07] Such a fabric has several disadvantages. For example, it requires that the protective clothing be worn over regular clothing: the user must therefore remember to put on the protective clothing when the situation requires it. In addition, the protective clothing must be correctly put on over the classic garment to cover the body optimally: a slippage between the two garments can lead to a defect in the protection. [08] It is then known to produce fabrics as a superposition of two layers: a technical layer made of technical yarn, and a comfort layer, made of yarn that is more pleasant for contact with the skin, for example yarn comprising wool or cotton. The two layers of the fabric are connected together by a so-called binding yarn, so as to keep them fixed relative to each other. The comfort layer is oriented towards the reverse side of the garment, so as to provide comfortable contact with the user's skin. [09] For example, document EP3237659 describes a fire and heat resistant textile, intended in particular for firefighters. According to one example, the first layer is made in weft and warp by a modacrylic (60%) and cotton (40%) thread, and the second layer is made in warp by a para-aramid thread, or a mixture of modacrylic (60%) and cotton (40%), and in warp by a para-aramid thread. [10] Document US2879654 proposes an undergarment providing protection against firearm bullets. The thread of the outer layer is a very high strength thread, for example nylon, and the inner layer, intended to be in contact with the skin, is made of a cotton/wool blend. [11] Document EP3545124 describes a fabric for clothing resistant to abrasion, and/or tearing and/or laceration and/or tearing and/or perforations. It comprises an upper layer, a lower layer and an intermediate layer. A thread connects the upper layer with the lower layer, and constitutes the intermediate layer. The upper layer is oriented outwards to protect against cuts and the lower layer is turned inwards in contact with the skin. [12] Such protective clothing therefore presents the technical yarn layer on the outside, that is to say that the technical layer will give the aesthetic appearance to the garment, which will necessarily be limited. Indeed, the coloring of technical yarns is not always feasible depending on the nature of the yarn, and in all cases it involves an additional cost. In addition, the arrangement of the yarns of the technical layer must primarily meet the protective function, so that the styles of knit to form the technical yarn layer are limited. [13] Therefore, a garment with a protective layer can be easily distinguished to the naked eye from clothing made of conventional thread, particularly due to its limited aesthetic aspect. A user wearing such a garment is then more easily spotted, which can cause problems when discretion is required. [14] The invention thus aims to provide a solution in particular to the aforementioned drawbacks. [15] A first aspect of the invention is to propose a new fabric for making a garment which provides effective protection against attacks. [16] A second aspect of the invention is to propose a new fabric for m
