EP2823096B1 - Sheathing knitted elastic lower body garment - Google Patents

Description

The present invention relates to an elastic knitted lingerie article constituting a bottom garment body garment, whether of panties type or incorporated in a longer garment such as a tights.

Sheathing clothes are designed to bring comfort, well-being and pleasure when wearing clothes, while erasing unsightly bulges, smoothing and reshaping the body without constraining it in its movements.

In order to provide better support for the belly at the front of the garment and the buttocks at the back, it is known from the document US 5465594 to knit (for example on a circular loom) the panty portion with different stitches and / or yarns especially at the plastron, which entails a certain complication of the knitting and a modification of the appearance of the knit which is not always desired.

It is also known from the document EP 2181613 , a bottom garment having a portion of pants on which was deposited a tight network of resin forming an elastic ring all around the pelvis for orthopedic purposes or physical exercise. On the one hand, it is not a sheath garment. On the other hand, the network of resin lines significantly changes the appearance of the garment, which is not necessarily suitable for users.

The documents US 2,196,492 , which served as a basis for the preamble to the attached claim 1, as well as DE 21 51 624 , DE 199 42 996 , EP 0 508 204 disclose resin applications on the base fabric of a panty.

The object of the invention is to provide a garment-lower body garment of modern appearance, smooth, without visible plastron.

The object of the invention is achieved by a lower body garment having a base elastic knit pants cooperating with the elastic resin applied to one side of the basic elastic knit of the pants, in front and / or at the rear of the panty, and comprising a lining provided to be applied on said face of the base knit at least at the location of said resin, characterized in that the resin is applied in the form of a resin network and in that the elastic liner is knitted lighter than the base knit and freely applies to said face of the base knit (and preferably over the entire front, front or back, on which the resin network is filed).

By elastic or elastomeric resin network deposited on one side of the garment, it is meant that the resin has been deposited so as to form more or less wide lines, more or less elongated surfaces, which give a certain elastic restraint in a preferential direction . These lines and surfaces form a network that can be more or less dense in places and be absent on certain areas of the surface of the garment. In any case, the resin is not arranged uniformly over the entire surface of the garment, but only on a part of it.

The face where the resin is applied is preferably the inner face and the liner is then internal, but one can also create a style effect by depositing the resin network on the outer face of the base knit and covering it with a outer lining.

Thanks to this constitution, especially in case of internal lining, the garment keeps a perfectly homogeneous appearance from the outside, the resin network is not directly visible. The inner lining is not intended to hide the resin network but considerably increases the comfort and eliminates the risk of allergy or irritation, This very light lining mesh, for example with a specific weight around 85 g / m ² , can even be translucent.

The inner or outer liner is advantageously applied with great freedom against the base knit layer, namely that it is not adhered to it over its entire surface, but simply fixed essentially peripherally for example on some points or lines, and for example preferably on the edges of the pants (belt, leg passages).

With this lightweight liner, it is possible to use fairly important resins that are generally avoided to use in the context of lingerie including silicone rubber type enough taut. Indeed, silicone rubber is an interesting material by its implementation and by its natural elasticity; but until then, its rather large adhesion made the uses in the outer face of undesirable undergarment to avoid hanging with the outer garment, and the uses on the inside of the underwear also undesirable because of unpleasant contacts with the skin , allergy problems and sweating. The outer or inner lining solves these difficulties.

The resin network includes an array of resin lines or surfaces disposed at the front and / or back of the panty. Particularly advantageously, when the network is provided only on one side (front or rear) of the pants, it is completed on the other side by a compression band that allows to create around the pants a d continuous ring of tension lines and to obtain interesting draw and push-up effects. This compression band may advantageously be a thermobonded textile band.

The elastic resin lines disposed on one face of the pants advantageously form a network which ends on the two lateral edges of the face in question, at least in a region (generally average and / or superior) of the edge; the ends of the strip join on the edges of the face of the pants the region of completion of the resin lines disposed on the other side. In this way, the ring effect mentioned above is obtained.

The lines of the elastic resin network are advantageously curved rather than straight.

In front, the network of curved lines consists of two symmetrical sets of lines from the front of the thigh to the opposite hip on the edge of the front face, the two sets crossing on the belly.

On the back, the network of curved lines consists of lines surrounding and framing the two inner areas of the glutens maximus to join one edge to the other of the rear face of the pants.

The basic knitting of the article, at the level of the pants, is made of jersey knit based on polyamide and elastane (preferably between 10% and 30% by weight of elastane relative to the total weight of the knit) . It advantageously has an elongation at 15 Newtons (according to BS 4952) equal to or greater than 110%, at least in length. The specific weight of the knit at the panty is advantageously of the order of 150 to 200 g / m ² (ISO 3801 standard).

The liner is advantageously a light mesh whose specific weight is between 60 and 100 g / m ² , and the elongation, at least in one direction, is equal to or greater than that of the base knit.

The silicone is advantageously a two-component silicone HTV. Its Shore A hardness is advantageously between 10 and 40.

Other features and advantages of the invention will emerge from the following description of two particular embodiments. Reference will be made to the accompanying drawings in which:

• The Figures 1A and 1B are front and back views of a first embodiment of pants according to the invention, the resin lines and contentive bands being shown visible as if the base knit was transparent.
• The Figures 2A and 2B are front and back views of a second embodiment of pants according to the invention, the resin lines and contained strips being shown visible as if the base knit was transparent.
• The figure 3 is a schematic sectional view of the layers constituting the pants of the invention.

The Figures 1A and 1B show the front and back of pants 1 according to the invention, which conventionally comprises an upper opening 2 for the torso and two lower openings 3 thigh (or leg). The panty 1 can be knitted in a circular loom and can be seamless (except possibly at the crotch piece 4); alternatively, it may consist of two front and rear panels knitted in a straight loom and sewn. The knit is elastic. The upper opening 2 comprises a not shown elastic belt, which may itself be obtained in any known manner, for example by integral knitting or by sewing, gluing, fusible bonded elastic piece, textile or not, or by applying a resin elastic.

The panty 1 is for example knitted in a charmeuse knit jersey with rows of polyamide son covered with elastane alternating with rows of unguided polyamide. The proportion of elastane in the knit is about 21% and the specific weight of the knit is 185 g / m ² and its elongation of 130% in the direction corresponding to the width of the panty.

The front 5 of the pants is covered in places with a network of silicone rubber according to a particular geometry in which one essentially distinguishes two crossed sets of curved lines more or less wide 7 from the upper and middle region of a side edge 8 of the pants 1 to the passage of the opposite leg 3, substantially towards the middle of the front of the thigh passage. These oblique and crossed lines 7 may have several widths and form a decorative pattern at the same time as they provide some elastic compression. These lines 7 may optionally be completed by an upper ventral panel 9 which extends under the belt between the two side edges 8 and points down towards the middle.

In fact, those lines 7 and 9 that were shown on the Figure 1A are applied on the inner face of the front 5 and are therefore not visible from the outside of the pants. The figures represent in fact a pair of panties that have been turned facing in and out.

The back 6 of the panty 1 comprises a strip of material 10 which goes from edge 8 to edge 8, at the same middle and upper edge portion 8 to which the crossed lines 7 of the front end and the panel 9. This strip of material containing 10 may be made by a deposited silicone rubber, but, more economically, it may be a strip of textile containing material laminated on the surface 6 (for example with points of polyamide glue) .

Again, the contention band 10 has been shown visible on the Figure 1B , but it is preferably applied to the inner face of the rear 6 and is not visible from the outside of the pants 1. However, it is also possible to provide it on the outer face of the rear 6 in the extent that it is not likely to interfere with clothing if it is made of a textile band and not silicone.

In a particular embodiment, the containment strip 10 is made by thermal gluing of a yoke made of the same material as the base knit, which it has just doubled the thickness.

The set of crossed lines 7 and the rear compression band 10 forms a kind of elastic cross-loop which acts effectively to maintain the abdomen. The lines 7 start from the left thigh, they rise to the waist in a fluid curve to finish on the right side. Lines 7 are doubled in mirror to adopt the same arrangement symmetrically from the right thigh to the waist on the left side. As shown, the lines 7 are advantageously curved, for example concave downwards, the curved lines being indeed more flexible and conformable than straight lines. The curved lines 7 intersect on the belly where they act to the maximum since the amount of silicone rubber deposited on the material is then more concentrated. The lines 7 are of different width (from 4mm to 40mm) and spaced apart (from 2 to 6mm), the widest line being in the example represented in the center of the lines 7.

The figure 3 schematically shows a section of the front of the pants 1 with the knit forming the front 5 on which are applied lines or surfaces 7 of silicone rubber, preferably on the inner face of the front. These applications sink very weakly into the knit 5 and do not pass through it, so that they are not directly visible on the other side of the knit 5. Above the base knit 5, a lining has been placed light interior 20 free on the bulk of the surface, at least in front of the network of crossed lines 7. The lining is attached to the base knit for example at the upper and lower borders corresponding to the passage of the torso 2 and the passage leg 3. The fixing can be done for example by gluing in a manner known per se, with an inset 21 glued or stitched, and / or stitching 22. Preferably, the liner 20 is provided on the entire front face, to the interior, and can also be provided on the entire backside although it is not technically essential where there is no silicone.

The lining is a mesh comprising 10% elastane for a specific knitting weight of 85 g / m ² . Its elongation is 145% in the direction corresponding to the width of the panties.

The silicone rubber is in a particular example a silicone (polydimethylsiloxane with vinyl groups and auxiliaries) brand Elastosil® and grade LR 3003/10 from Wacker, heat-curable, and two-component (A + B). The silicone is screen printed on one side of the panties and heat-cured (for example 175 ° C. for 30 seconds under infrared, other heating modes being of course possible). The thickness of silicone deposited is about 0.20 to 0.25 mm (a thickness of the order of that of the base knit), which for the various sizes of pants considered represents a total weight of 16 g to 23 g.

Various measures of the maximum elongation A (in the width of the panty, unless otherwise specified), the return force F, as well as the return force F30 at 30% elongation were made for various combinations. of layers comprising the base knit (T), the liner (D), the base knit + silicone (TS), the base knit + containment tape (TC): T A = 130% F = 425cN at 80% F30 = 200cN D A = 145% F = 195cN at 80% F30 = 100cN TS A = 61% F = 1191cN at 50% F30 = 1000cN TS + D A = 47% F30 = 939cN TC A = 40% F30 = 828cN

These measurements show that with the application of silicone, the basic knit retains an elongation of 61% and has become five times more nervous (what F30 indicates). The material is therefore far from rigid. As a result, the article is easier to put on and the material accompanies the movements of the body while compressing the belly and the waist.

The influence of the addition of the lining on the elongation and the nervousness of the raw material with the application of the silicone is tiny. On the other hand, as indicated above, its protective role is essential.

Measurements of elongation and nervousness of the complex on the back side at the waist and hips are in continuity with those found on the front sides of the product. The draw starts from the left thigh, rises, crosses the belly to the right side at the waist and joins the yoke of the back, which takes over and goes around the back. On the other side of the waist (left front) the new silicone lines take over to pull on the belly like an elastic bandage and they end up on the right thigh.

The Figures 2A and 2B show another embodiment where the silicone is applied to the back of the pants to obtain a lift effect of the buttocks. In this case, the rear portion 6 of the panty 1 comprises, on its inner face, a network of curved lines 7 'of silicone rubber which are here arranged so as to surround the region 12 in the form of ossicles or kidneys, and corresponding substantially to the inner zone of glutens maximus. Some of the curved lines 7 'almost completely surround the zone 12, like the line 7'a, others border more widely this area and join the opposite edges 8, as the lines 7'b. The set of lines 7 'leading to the edges 8 end there in a median zone of the edge 8 where the elastic traction forces are taken up on the other side of the pants, that is to say at the front 5, by a band 10 'similar to the band 10 of the Figure 1B and possibly concave on its lower part like it. As in the previous embodiment, there is provided a light lining intended to be freely disposed at least in front of the line networks 7 ', that is to say on the rear portion of the pants. The lining can extend over all the panties too.

The zone 12 (at least its lower part) and the neighboring silicone lines 7 'at the bottom of the zone 12 are advantageously arranged in a curved thermoforming mold to give a shape to the rear part of the panties. During this operation, only the textile takes the rounded form, the silicone retaining its previous shape memory.

Wear tests were performed with both embodiments and showed 100% satisfaction from the users.

We have described here an independent panty but the invention can be applied to the panty portion of a longer garment and even a pantyhose.
