Definitions

  • the present invention relates to a compression article comprising a knit of at least one mesh yarn forming stitches and at least one weft yarn and having an internal face intended to be in contact with the skin of a user of said article , at least the weft thread being made at least partly of elastic material, said weft thread being arranged to perform the compression function of said compression article.
  • Such a compression item is for example stockings, tights, tight-fitting boxer shorts or leggings, corsairs, a compression sock, a knee pad, an elbow pad, a sports sleeve for the shin, thigh or arm or any other type of compression item.
  • WO 2012/028795 A1 describes a compression orthosis comprising an embossed zone comprising a first type of stitches formed of knitting threads and in which elastic weft threads are inserted in all the stitches and a second type of stitches formed of knitting threads and in which threads Weft elastics form floats of at least two needles, that is to say that the weft threads are not inserted in all the stitches.
  • Such a type of orthosis is essentially used to provide compression of a limb, for example in the context of the treatment or prevention of venous pathologies.
  • the compression function is provided by the weft yarn which is generally a gimped yarn, comprising a core yarn and possibly one or more covering yarns gimped onto the core yarn, that is to say wound around the soul thread.
  • An aim of the invention is therefore to increase the usefulness and/or comfort of a compression article.
  • the invention relates to a compression article according to claim 1.
  • the weft thread designed to be in contact with the user's skin, makes it possible in particular to achieve an anti-slip function in addition to its compression function.
  • This additional function can thus be used to improve the comfort of the patient wearing the compression article.
  • the contribution of this function is improved in the zone in which the weft thread forms weft floats because the contact surface between the weft thread and the patient's skin is increased in this zone.
  • FIG. 1 represents a compression article 10.
  • the article represented is a compression sock, but the invention also applies to any other compression article, such as a knee brace, stockings or tights, a sleeve offering compression, a sports sleeve or something else.
  • the article has, for example, a medical application, in the field of sport or otherwise.
  • only a compression sock will be described, the teachings of the invention applying in a similar manner to any other compression article.
  • the compression article 10 has a substantially tubular shape in knitted textile. It comprises, for example, a first part 12 closed at one end intended to envelop the foot of a user and a second part 14 open at one end intended to surround the ankle and the calf.
  • the end parts 16 of the first part 12 of the compression article 10 intended to be located at the front and rear ends of the foot are reinforced.
  • the compression article 10 is open at a front end of the user's foot.
  • the compression article 10 comprises a knit having an internal face intended to be in contact with the skin of a user and an external face visible from outside the compression article.
  • the knitting comprises at least one stitch thread 20 forming stitches 22 and at least one weft thread 24.
  • the compression article 10 has, for example, a weft thread 24 every three rows of stitches 22.
  • the compression article has a weft thread every row of mesh.
  • the mesh yarn 20 comprises an elastic yarn, for example, made of elastane or silicone.
  • the wire is bare, covered with one or two threads, for example polyamide, or covered using a pulsed air technique.
  • the stitches are, for example, made with a jersey structure. Such a structure being known, it will not be described in more detail here. It is understood, however, that the stitches could have another type of structure, such as a ribbed structure knitted on a double cylinder loom for example.
  • the weft thread 24 is made at least partly of elastic material.
  • elastic is meant a material that can undergo an elongation of at least 30% in at least one direction when it is stretched and return to its initial length in the absence of stretching applied to the wire.
  • the weft thread 24 comprises, for example, a core 26 of elastic material.
  • the weft thread 24 is bare.
  • the weft thread 24 here comprises at least one covering thread 28 extending over the core 26.
  • the covering wire 28 is wrapped around the core 26.
  • the covering wire 28 is, for example, wound helically around the core 26 or intertwined with the core by a pulsed air technique, commonly called "air jet”.
  • the weft thread is a double wrapped thread, that is to say a covered thread with two covering threads wound in two opposite winding directions around the core thread, as shown in the figure. figure 2 .
  • the weft yarn 24 has an average count strictly greater than 200 dtex, more particularly strictly greater than 300 dtex, this unit being defined such that 10 kilometers of a yarn having a count equal to n dtex has a weight of n grams, the wire not being elongated.
  • the weft thread 24 is arranged to perform the compression function of the compression article 10, in particular thanks to the elasticity of the core of the weft thread.
  • the compression article 10 exerts compression on a limb of the user once the compression article 10 is in place.
  • this compression article 10 is designed to produce an ankle pressure greater than 13 hPa.
  • the article 10 comprises at least one zone 32, different embodiments of the knitting of which are represented in the figures 3 and 4 , in which the weft thread 24 is inserted into some of the meshes 22 and passes without insertion on the internal face of other meshes 22.
  • the weft thread 24 thus forms floats 34 on the internal face of the zone 32, it that is, the floats 34 are in contact with the user's skin when the compression article is worn.
  • the floats 34 are defined by the parts of the weft thread which are not inserted into the stitches 22. The weft thread 24 thus forms loads with the stitches 22.
  • the meshes 22 in which the different weft threads are inserted are offset in a transverse direction Y perpendicular to the longitudinal direction X in which each weft thread extends, for example, by two or three meshes.
  • the floats are thus not aligned along columns in the transverse direction Y.
  • the floats are, for example, arranged in a staggered manner every two or three rows.
  • the meshes 22 in which the different weft threads are inserted are aligned in the transverse direction Y, so that the floats form columns in the transverse direction Y.
  • Zone 32 has a single thickness of knitting, that is to say that the knitting forms both the internal face and the external face of zone 32 and that it is not folded on itself in the area 32.
  • the zone 32 is localized, that is to say it does not extend over the entire compression article 10.
  • the compression article comprises a main zone 30, in which the weft thread is inserted in all the stitches and at least one zone 32, called secondary zone 32, in which the weft thread 10 forms the weft floats.
  • the weft thread is not inserted into all the stitches, so as to form floats.
  • the size of the floats in the main zone 30 is, for example, less than or equal to the size of the floats in zone 32.
  • the compression article comprises a secondary zone 32 extending at least partially over an end part of the compression article, the end part being located near one end of the compression article 10.
  • Zone 32 can extend over all or part of the circumference of the article, that is to say it can be designed to go all the way around the user's limb or only part of it. this round.
  • the end part is the upper part of the second part 14 surrounding the calf extending near the open upper end of the second part 14.
  • the secondary zone 32 is here of tubular shape and spaced less than 20 mm apart, preferably less than 10 mm, from the upper end of the second part 14.
  • the secondary zone 32 has, for example, a dimension in the transverse direction Y of between 30 mm and 250 mm depending on the location of the secondary zone 32 and the nature of the compression item.
  • the main zone 30 forms the rest of the compression article 10.
  • the compression article 10 comprises several secondary zones 32 separated from each other by the main zone.
  • the secondary zone(s) 32 are arranged at one or more locations where it is desired that the weft thread provides an additional function, in addition to the compression function, as will be described later.
  • a secondary zone 32 is, for example, arranged at each end of the compression article 10.
  • the zone 32 presenting the floats 34 extends over the entire compression article 10, that is to say that the compression article then does not include a main zone.
  • the weft thread 24 is arranged to perform the compression function and at least one anti-slip function. This additional function is carried out by the nature and/or by treatment of the weft thread 24 and by interaction with the skin of a user in zone 32. This function is carried out in a particularly effective manner by the weft floats because the weft thread 24 has an increased contact surface with the user's skin in these floats.
  • anti-slip means that the zone 32 has a particular adhesion with the skin of the user by a friction effect between the weft thread 24 and the skin of the user.
  • the compression article does not roll on the user's skin or does not roll up on itself at the level of zone 32.
  • the force of gravity is not sufficient to move zone 32 on the skin of the user, so that the compression article remains in place during use, for example, over the course of a day. A user is nevertheless able to remove the compression article without having to exert significant force.
  • the anti-slip function is ensured by the nature and/or by a treatment of the weft thread 24.
  • the anti-slip function is provided by the covering thread 28 extending over the core 26.
  • the covering thread 28 is arranged to perform at least one anti-slip function , in addition to its participation in the compression function, by its nature and/or by treatment of said covering thread 28 and by interaction with the user's skin at least in said zone 32.
  • the covering wire 28 protects the core 26. This allows in particular better solidity of the compression article. Furthermore, during normal use, the core 26, due to its extension around the user's limb, becomes thinner, unlike the covering wire 28. Thus, the covering wire 28 makes it possible to maintain a large contact surface with the skin, and thus an effective anti-slip function.
  • the 20 mesh yarn includes an elastane or silicone core and two polyamide cover yarns.
  • the core has an average count substantially equal to 44 dtex and each covering thread has an average count substantially equal to 22 dtex.
  • the weft thread 24 comprises a core 26 of elastane or silicone thread and at least one covering thread 28 of elastane or silicone, for example, two covering threads wrapped around the core 26.
  • the core 26 of the weft thread 24 has an average count substantially equal to 285 dtex and each covering thread 28 has an average count substantially equal to 22 dtex.
  • zone 32 prevents the compression article 10 from sliding on the user's skin.
  • the compression article thus offers increased comfort, by eliminating a tourniquet effect which may be caused by a cuff or an overly tight part, generally provided at the end of the compression article to ensure good support of the article. on the user's member.
  • a tourniquet effect which may be caused by a cuff or an overly tight part, generally provided at the end of the compression article to ensure good support of the article. on the user's member.
  • the elimination of the tourniquet effect also improves the effectiveness of the compression provided by the compression article, the tourniquet effect being contrary to the desired aim.
  • the compression article has, for example, a single limited double-thickness zone 36 included in the main zone 30.
  • the double-thickness zone is located at one end of the article, that is to say that the zone double thickness is at all points located less than 20 mm, preferably less than 10 mm, from the end.
  • Said zone 36 is, for example, between zone 32 and the end of the article, as shown in the figure 1 .
  • the weft thread 24 is only inserted on the external face of zone 36 then continues into zone 32 so as not to accumulate two weft thicknesses, which may be responsible for a tourniquet effect.
  • the weft thread 24 is arranged to perform one or more additional functions, other than an anti-slip function. This or these additional functions are a variation or combination of the anti-slip function.
  • the area 32 presenting the floats 34 forms a ribbed pattern of the compression article.
  • the covering thread 28 of the weft thread 24 therefore makes it possible to perform additional functions with the compression article. This offers, for example, increased comfort or efficiency.
  • the compression article 10 could be arranged to provide an anti-slip function in an extreme part of the compression article and a bacteriostatic or antifungal function against a weakened area of the limb.
  • the compression article described above can be produced on a single cylinder loom.
  • the creation of a mesh pattern is done by loading the weft thread, thus creating weft floats on the internal face.
  • the compression article described above may be made on a double cylinder loom.
  • the weft yarn is placed between the knit stitches and the purl stitches in a regular ribbed construction.
  • the floats are for example obtained by forming a cable pattern.
