[0046] Specific embodiments of the invention will now be described with reference to the accompanying drawings, in which:

[0047] FIG. 1 is a front view of a lower body garment according to the invention;

[0048] FIG. 2 is a back view of the lower body garment; and

[0049] FIG. 3 is a schematic cross-sectional view of the lower body garment taken along line A—A in FIG. 2.

DETAILED DESCRIPTION

[0050] The invention provides a durable lower body garment. As used herein, the term “durable” refers to a garment capable of being laundered and/or reused, and is used to distinguish the garment from garments that are designed and constructed for single-use, i.e. disposable garments for infant, geriatric and specialized healthcare use. The term “sportswear” refers to garments adapted for use while the wearer is engaged in sports activities, in particular high intensity or endurance sports activities.

[0051] An embodiment of the durable lower body garment of the invention in the form of a pair of briefs 1 is shown in FIGS. 1 and 2. FIG. 1 is a front view of the briefs 1 and FIG. 2 is a back view of the briefs 1. The briefs 1, excluding any decorative elements such as labels and printing, are symmetrical about a longitudinal centreline L which divides the briefs 1 into left and right side halves.

[0052] The briefs 1 have a front region 3, a back region 5 and a crotch region 7 arranged in between the front region 3 and the back region 5. The crotch region 7 is narrower than the front and back regions 3, 5, and the front and back regions 3, 5, are connected to define a waist opening 9 and a pair of leg openings 11, 13. It should be noted that the connection between the front and back regions 3, 5 may or may not correspond to a physical joint. In the illustrated embodiment, a physical joint is not present, and the boundary between the regions is instead notional. Likewise, the boundary between the front and back regions 3, 5 and the crotch region 7 may correspond to a physical join or be notional.

[0053] The briefs 1 shown in FIGS. 1 and 2 are formed of a plurality of panels 17, 19, 21, 23, each formed of an elastically stretchable fabric. By “elastically stretchable”, it is meant that the fabric of the panels can be elongated by at least 50% when a force is applied and, when the force is removed, will recover essentially all of its elongation. Elastically stretchable fabrics of this type will be known to persons skilled in the art. The fabric of the panels is stretchable in in this way in two orthogonal directions, i.e. it has bi-directional elasticity.

[0054] The fabric panels include a front fabric panel 17; a plurality of further fabric panels in the form of a back fabric panel 19, a left side fabric panel 21 and a right side fabric panel 23; and also a crotch fabric panel 25. The briefs 1 in their assembled state have a wearer (skin) facing surface 27, which faces inwardly, and an outer garment facing surface 29, which faces outwardly.

[0055] In the illustrated embodiment, the fabric panels 17, 19, 21, 23, 25 are formed of a knitted fabric consisting of 90% by weight polyester and 10% by weight elastane (spandex). In alternative embodiments, the fabric panels may be formed of other types of knitted fabric, and even woven fabrics, as long as the fabric has suitable elastic properties. Each of the fabric panels is defined by a single piece of the knitted fabric.

[0056] The waist opening 9 of the briefs 1 defines a waist edge 31 which encircles the wearer when the briefs 1 are worn. The waist edge 31 is defined by the front fabric panel 17 and the further fabric panels 19, 21, 23. In particular, 70% of the total length of the waist edge 31 (in the unworn state) is defined by the further fabric panels 19, 21, 23 and 30% of the total length of the waist edge 31 (in the unworn state) is defined by the front fabric panel 17.

[0057] The front fabric panel 17 and the further fabric panels 19, 21, 23 extend from the waist edge 31 to the crotch region 7. Lateral edges of the front fabric panel 17 are joined to respective lateral edges of the left side fabric panel 21 and the right side fabric panel 23. The back fabric panel 19 is then joined along its lateral edges to respective lateral edges of the left side fabric panel 21 and the right side fabric panel 23. In this way, the panels form a structure which surrounds the wearer, in use.

[0058] A width of the front and back fabric panels 17, 19 tapers down towards the crotch region 7 of the briefs 1, so as to provide a close-fitting garment.

[0059] The crotch fabric panel 25 is centred on the crotch region 7 of the briefs 1. End edges of the front fabric panel 17 and the back fabric panel 19 are joined to respective end edges of the crotch fabric panel 25. Lateral edges of the crotch fabric panel 25 define parts of the leg openings 11, 13.

[0060] The joins between the adjacent fabric panels, and between the fabric panels and the elastic waistband 15, may be formed as flatlock seams. The leg openings 11, 13 may be hemmed.

[0061] According to the invention, the front fabric panel 17 is folded along the waist edge 31 to define a front waist hem 33 at the inner surface of the garment 1 and the further fabric panels in the form of the back fabric panel 19, the left side fabric panel 21 and the right side fabric panel 23 are folded along the waist edge to define a further waist hem 35 at the inner surface of the garment 1. The hems are not directly visible in FIGS. 1 and 2, but the end edges of the hems are indicated by dashed lines. The front waist hem 33 and the further waist hem 35 each have a depth 50 mm, although it should be noted that the depth of the hems 33, 35 may be different to this and different to each other.

[0062] The front waist hem 33 and the further waist hem 35 are configured to be ungathered when the garment 1 is in the unworn state, by which it is meant that they do not exhibit the typically ruffled appearance of a gathered elastic waistband.

[0063] As illustrated in the partial cross-section of FIG. 3, the front waist hem 33 and the further waist hem 35 are provided with layer or strip of thermoplastic polyurethane 37, which is a thermoplastic elastomer that serves to bond the hems 33, 35 together and at the same time restrict the elastic elongation of the hems 33, 35 when a load is applied along the direction of the waist edge 31. The thermoplastic polyurethane 37, which is a hemming material that is known in the art, is applied as a pre-fabricated sheet during manufacture of the garment and is activated by heat and/or pressure once the hems 33, 35 have been formed. In this way, the garment 1 is provided with a waistband that has a higher elastic modulus (corresponding to a lower elongation under load) than the remainder of the fabric panels that make up the garment.

[0064] The amount of the thermoplastic polyurethane 37 per unit length of hem in the further waist hem 35 is greater than the amount of the thermoplastic polyurethane 37 per unit length of hem the front waist hem 33. In this way, the rear part of the waistband defined by the further waist hem 35 has a higher elastic modulus (or lower elongation under load) than the front part of the waistband defined by the front waist hem 33.

[0065] In particular, the front waist hem 33 of the specific embodiment exhibits an elongation under a load of 3.6 kg, in a direction about the waist opening, of approximately 60%. The further waist hem 35 exhibits an elongation under a load of 3.6 kg, in a direction about the waist opening, of approximately 40%. The measured elongation is therefore 50% greater in the front waist hem 33 than it is in the further waist hem (60%/40%). Such an elongation relationship has been found to provide enhanced comfort in the abdominal region by ensuring that the force which is carried through the waistband is distributed more through the enlarged area of the front fabric panel and less through the relatively narrow front waistband area. This has been found to reduces the stress on the wearer's abdomen.

[0066] The differential elastic properties can also be expressed in terms of the force at 40% elongation (also referred to herein as the “modulus”) exhibited by the waist hems. In particular the force at 40% elongation should be at least 20% greater in the further waist hem 35 than in the front waist hem 33 to provide optimal abdominal comfort.

[0067] The waistband region of the briefs 1 shown in FIGS. 1 to 3 also comprises three discrete gripping elements 39 formed on the wearer facing surface 27 (these are hidden from view in FIGS. 1 and 2 but a single one of the gripping elements 35 can be seen in the cross-sectional view of FIG. 3). The gripping elements 35 are formed of a silicone material applied directly to the further waist hem 35. The gripping elements are arranged on the elastic waistband 15 only in the areas of the wearer's hips and back. No gripping elements are provided on the front waist hem 33. It has been found by experimentation that optimal comfort (i.e. measured as reduced dynamic pressure peaks during sports exercise) is provided with such a configuration. Such a configuration also reduces friction and therefore discomfort particularly in the lower abdominal region.

[0068] A specific embodiment of the inventive garment of the invention has been described in detail. Various changes may be made to the specific embodiment without departing from the invention, which is defined solely by the claims. Such changes will be apparent to the skilled person.

[0069] As used herein, values for elongation under a load of 3.6 kg and for force at 40% elongation, given in relation to the front waist hem and the further waist hem, are to be measured using a modified version of BS EN ISO 20932-3:2020 (Textiles—Determination of the elasticity of fabrics).

[0070] In particular, elongate test specimens are to be obtained by carefully cutting the front waist hem and the further waist hem from the garment using shears. A fixed width of the waist regions is removed, which width corresponds to the maximum depth of the front and further waist hems. In this way, the test specimen comprising the entire front waist hem and the test specimen comprising the entire further waist hem have the same width, so that measurement results are comparable, even where the hems have a different depth. The specimen length corresponds to the entire length of the front waist panel along the waist edge (for the front waist hem) and the entire combined length of the further waist panels along the waist edge (for the further waist hem). The test specimens will in general have different lengths, but the elongation is calculated in percentage terms.

[0071] The test specimens are tested using “Method A” of BS EN ISO 20932-3:2020, with a specified force of 3.6 kg and five cycles, with measurements being taken on the fifth cycle. The test specimens are clamped in the jaws of the testing machine so that the gauge length is 50 mm smaller than the specimen length, with 25 mm of the specimen length being arranged in the jaws at each end.

[0072] The elongation under a load of 3.6 kg for a component is expressed in terms of a percentage (extension of the test specimen as a percentage of its initial length). According to the invention, an elongation under a load of 3.6 kg exhibited by the front waist hem, in a direction about the waist opening, is at least 10% (or some other figure) greater than an elongation under a load of 3.6 kg exhibited by the further waist hem, in a direction about the waist opening. For the avoidance of doubt, this 10% figure (and corresponding other figures), refers to a relative measurement (elongation of the front waist hem as a percentage of elongation of the further waist hem). It does not refer to an absolute measurement, even though the underlying elongation under a load of 3.6 kg is also expressed in terms of a percentage.
