DETAILED DESCRIPTION

(6) The easy on/off compression 1 garment shown in FIG. 1 is a compression sock 1 comprising a compression knitted piece 10, made entirely by knitting.

(7) This knitted piece 10 includes a toe part 2, which may be closed after knitting (for example by sewing), a knitted foot part 3, and in its extension a part corresponding to the knitted leg 4 ending with a cuff 5.

(8) This knitted piece 10 comprises a stitch ground yarn 20, in particular elastic, an inlaid elastic yarn 30, and a hairy yarn 40 knitted into knitted piece 10 in such a way that knitted piece 10 has, according to all or part of its inner face 12 and its outer face 14, hairs 50 projecting from the latter, said hairs 50 being configured in such a way as to orient itself in the direction of slipping on F1 and/or of F2 of the knitted piece 10. The hairs 50 are distributed in sections 55 or segments 55 of yarns projecting from the core 45 of the hairy yarn 40. These sections 55 may comprise/be each made up of a first end 56 joined to the core 45 of the hairy yarn, and a second free end 57 configured to adopt a direction corresponding to the direction of slipping on or off. The hairy yarn 40 comprises a core 45 and hairs 50 projecting from said core 45. The core 45 is knitted. Additionally, the core 45 may be knitted including a pillar stitches in which the hairs 50 are anchored. The core 45 of the hairy yarn 40 is knitted with multifilament yarns and/or spun yarns of fibers, each made of polyamide with a titer of about 44 dtex. The hairs 50 anchored when knitting the hairy yarn 40 on a crochet machine are formed by viscose yarns, each with a titer of the order of 44 dtex. The hairy yarn 40 has a titer of the order of 23,000 Nm.

(9) The number of sections 55 of hairs 50 per centimeter measured along the length of the hairy yarn 40 is greater than or equal to 3 and less than or equal to 10, in particular of the order of 4. The weft elastic yarn 30 comprises an elastic core of elastane with a titer of the order of 620 dtex, and two wrapped polyamide cover yarns, each of which has a titer of the order of 22 dtex. A first cover yarn is wrapped in the direction S while the second cover yarn is wrapped in the direction Z. Finally, the knitted piece 10 comprises an inlaid elastic yarn 30 arranged in a row of stitches T, as shown in FIG. 6, between two rows of stitches M1 and M2, each comprising at least one stitch hairy yarn 40, in particular the reverse side on all needles. The row of stitches T is arranged between the adjacent rows M1 and M2, and the length of at least 80% of the hairs 50 of said at least one hairy yarn 40 in one of the rows of stitches M1 and M2 is greater than or equal to the distance d between the rows of stitches M1 and M2. The distance d shown schematically in FIG. 6 is not evaluated on the knitting machine but on the relaxed knitted piece 10, in particular under the hygrometric and temperature conditions defined in the standard NF ISO 139:2005. The hairs 50 thus have, for at least 80% in number, preferably at least 95% in number, for example a length of the order of 2 mm f 7%. The hairy yarn 40 may form stitches, in particular tuck stitches and/or loop stitches, and is not inlaid. Finally, the ground yarn 20 is elastic and thus comprises an elastane core with a titer of the order of 44 dtex and two cover yarns, in particular polyamide, in particular wrapped, each with a titer of the order of 78 dtex.

(10) The first example of the stitch pattern in FIG. 3 thus comprises a first row of jersey stitches 60, in particular reverse stitches, knitted on all needles with the hairy yarn 40, a second row 62 of stitches loaded every other needle knitted with the weft elastic yarn 30, a third row 64 of jersey stitches, notably reverse stitches, knitted on all the needles with the elastic stitch ground yarn 20, and finally a fourth row of tuck stitches 66 one needle out of two, staggered with the second row of tuck stitches 62, and knitted with the weft elastic yarn 30. This stitch pattern corresponds in particular to the compressive structure from the welt of the malleolus to the welt 5 of the compression garment 1, i.e., substantially to the leg part 4.

(11) The second example of a stitch pattern in FIG. 4 includes a first row of jersey stitches 70, in particular reverse stitches, knitted on all needles with the hairy yarn 40, a second row 72 of tuck stitches every other needle knitted with the weft elastic yarn 30, a third row 74 of jersey stitches, in particular reverse stitches, knitted on all the needles with the elastic stitch ground yarn 20, and finally a fourth row of tuck stitches 76 every other needle, identical to the second row of tuck stitches 72, and knitted with the weft elastic yarn 30. This stitch pattern corresponds in particular to a ribbed structure of the compression garment 1 assigned by the weft yarn, in particular arranged at the compressive structure from the welt of the malleolus to underneath the welt 5 of the garment 1, i.e., substantially at the leg part 4.

(12) The third example of a stitch pattern in FIG. 5 includes a first row of jersey stitches 80, in particular reverse stiches, knitted on all needles with the hairy yarn 40, a second row 82 of tuck stitches every other needle knitted with the weft elastic yarn 30, a third row of 84 loop stitches every other needle, in particular reverse stitches, in the elastic stitch ground yarn 20, and finally a fourth row of tuck stitches 86 every other needle, staggered with the second row of tuck stitches 82, and knitted with the weft elastic yarn 30. This stitch pattern corresponds in particular to a ribbed structure of the compression garment 1 assigned by the elastic stitch ground yarn 20, in particular arranged at the level of the compressive structure from the welt of the malleolus to below the welt 5 of the garment 1, (i.e., corresponding substantially to the leg part 4).

(13) Advantageously, the stitch pattern, the density and the hairs 50 length make it possible to precisely determine the desired velvet effect for the knitted garment 10, and thus to impact the shearing effect of the elastic yarns 30, and consequently to make the compression garment 1 easy to slip on and off. It is also possible to combine this effect with different knitted structures, for example with a ribbed effect as described above.
