AI Technical Summary
Conventional methods for locally reducing elasticity in elastic garments, such as elastic sports trousers, often result in an uneven appearance, increased manufacturing complexity, and limited design options due to the use of seams or different fabrics.
The use of a reinforcing band attached to spaced-apart fastening sections on the inside of the trousers, spanning the elastic textile without being attached, to reduce elasticity without altering the fabric, allowing seamless construction and uniform appearance.
This approach achieves a uniform appearance and expanded design possibilities while maintaining comfort, reducing the need for additional seams and fabric limitations, and creating a 'scrunch' effect.
Description
[0001] The invention relates to trousers, in particular leggings, and to a method for manufacturing trousers. Technical background
[0002] Elastic garments, particularly elastic trousers such as elastic sports trousers or leggings, are known that consist essentially of elastic fabric and in which elasticity is selectively reduced at certain points. To facilitate a better fit, the elasticity of some such garments is reduced at selected locations, as well as, for example, parallel to a specific direction of the elastic fabric's length. This local reduction of elasticity in one or more directions of length is conventionally achieved by adding seams to the elastic fabric or by using a differently woven, for example, denser, fabric in those areas.
[0003] US patent 2014 / 0273742 A1 discloses a garment that supports the wearer's buttocks, as well as a manufacturing method for such a buttock-lifting garment.
[0004] US 2018 / 0289077 describes an undergarment and, in particular, an adjustable undergarment.
[0005] RU 171883 U1 discloses buttock-firming garments, especially trousers.
[0006] Documents US 2014 / 0273742 A1 and RU 171883 U1 disclose the preamble of claim 1.
[0007] Conventional techniques for locally reducing the elasticity of a garment can have disadvantages, particularly due to seams or the use of different fabrics in certain areas, resulting in an undesirable, uneven appearance. Furthermore, some of these techniques, such as the use of different fabrics in specific areas, place relatively high demands on the complexity and precision of the entire garment manufacturing process. Additionally, some of these techniques limit the selection of usable textiles and possible designs.
[0008] Therefore, a technique that avoids or reduces the aforementioned disadvantages is desirable. Summary of Revelation
[0009] This problem is solved by trousers according to claim 1 and a method according to claim 15.
[0010] According to a first aspect, trousers, in particular leggings, are presented. The trousers comprise elastic textile and are elastic at least in one seat area. The trousers further comprise at least one reinforcing band, which is attached to at least two spaced-apart fastening sections located on the inside of the trousers and which spans the elastic textile in an area between the fastening sections without being attached. The reinforcing band is designed to reduce the elasticity of the trousers in the seat area between the fastening sections.
[0011] The reinforcing band reduces the elasticity of the trousers between the attachment points without requiring any modification of the elastic fabric between these points, particularly through seams and / or the use of a different weave. This promotes a uniform appearance of the trousers, especially the elastic fabric, in the area between the attachment points and in relation to the surrounding area. This is achieved because the reinforcing band stretches unattached across the elastic fabric in the area between the attachment points.
[0012] In particular, the reinforcing strap can be attached to the inside of the trousers, especially with respect to the inside of the elastic textile, by means of the at least two spaced-apart fastening sections of the reinforcing strap, and in particular over a length of each of the at least two fastening sections of the reinforcing strap.
[0013] The reinforcing cable can be elastic.
[0014] The reinforcing strip can be designed to reduce the elasticity of the trousers parallel to the direction of separation of the fastening sections. Additionally or alternatively, the reinforcing strip can be designed to at least substantially prevent the reduction of the elasticity of the trousers orthogonal to the direction of separation of the fastening sections.
[0015] The elastic textile can be elastic in the buttocks area in an extension plane of the elastic textile parallel to a spacing direction of the fastening sections and orthogonal to the spacing direction of the fastening sections.
[0016] The fastening sections can be spaced apart from each other with respect to a central plane, i.e., a crotch plane, of the trousers. In particular, the reinforcing strip can extend along the central plane of the trousers.
[0017] The use of the reinforcement strip in conjunction with trousers facilitates the placement of one or more of the attachment sections at one or more seams already present in the trousers due to the manufacturing process, particularly a waistband seam, an inseam, and / or a crotch seam. This reduces the need for additional seams at other points on the trousers, especially on other areas of the elastic fabric. This promotes a uniform appearance of the trousers and reduces potential limitations regarding usable fabrics and / or designs.
[0018] The placement of the reinforcement strip along the center seam, and the resulting reduction in elasticity of the pants along this seam, creates the so-called "scrunch" effect. Combined with the above, this design facilitates the creation of scrunch leggings with an improved, and in particular more uniform, appearance, as well as expanded possibilities regarding the fabrics and / or designs used. The reinforcement strip's placement along the center line in the seat area allows the pants to be worn without any limitations in terms of comfort.
[0019] The elastic textile can be manufactured seamlessly in the area between the fastening sections, in particular seamlessly woven and / or seamlessly knitted. This promotes a uniform appearance and / or wearing comfort of the elastic textile.
[0020] The elastic fabric can have various structures that are uniform across a given horizontal plane of the trousers and change along the length of the trousers. This can be achieved through seamless weaving or knitting of the elastic fabric.
[0021] The area between the fastening sections can extend at least partially into the hip plane of the trousers. Additionally or alternatively, the elastic fabric can be seamlessly manufactured along the hip plane, particularly using circular weaving and / or circular knitting. This promotes a uniform appearance of the elastic fabric in the hip area. Furthermore, this design of the trousers facilitates the production of, in particular, scrunch leggings using tubular, especially circular-woven and / or circular-knit, raw material.
[0022] A first fastening section of at least two fastening sections can be arranged on a waistband of the trousers.
[0023] A second fastening section, or at least two fastening sections, can be arranged on an inner seam of the trousers.
[0024] The second fastening section comprises a fastening seam that extends at least partially parallel to the spacing direction of the fastening sections and by means of which the reinforcing pull is sewn to the elastic textile.
[0025] The fastening seam allows, particularly given a specific overall length of the reinforcement strip, the length and / or position of the area between the fastening sections where the reinforcement strip spans the elastic fabric without being attached. This improves or optimizes the fit of the elastic fabric to the body and / or the comfort of the trousers.
[0026] The fastening seam can be designed in such a way that, in an unstretched state of the reinforcing tension, the elastic textile is gathered in the area of the fastening seam.
[0027] In an unstretched state of the reinforcing strip, the ratio between the length of the reinforcing strip and the length of the fastening seam is in a range between 1.2 and 5, preferably between 1.4 and 3, more preferably between 1.6 and 2.4.
[0028] Such a ratio of different lengths promotes a favorable fit of the trousers to achieve a scrunch effect, without significantly compromising the aforementioned advantages of the trousers, particularly regarding a uniform appearance and freedom of material and design in the hip area. Furthermore, such a ratio enhances wearing comfort by ensuring the reinforcement lies close to the body.
[0029] The elastic textile can, at least in the area between the fastening sections, exhibit a lower modulus of elasticity than the reinforcing strip with respect to elongation parallel to the spacing direction of the fastening sections. In particular, the elastic textile adjacent to an entire length of the reinforcing strip can exhibit a lower modulus of elasticity than the reinforcing strip with respect to elongation parallel to the spacing direction of the fastening sections.
[0030] Such a ratio of elasticity moduli also promotes a favorable fit of the trousers to achieve a scrunch effect and wearing comfort, without significantly impairing the aforementioned advantages of the trousers in terms of a uniform appearance and freedom of material and design.
[0031] In an unstretched state, the length of the reinforcing cable can be between 3 and 16 centimeters, preferably between 5 and 12 centimeters, preferably between 6 and 10 centimeters.
[0032] The length of the reinforcing strip can correspond, at least substantially, to a distance between the inner seam and an outer end of the first fastening section of at least two fastening sections.
[0033] The elastic textile may comprise elastic synthetic fabric. The elastic textile may comprise at least one polyamide, polyester, and / or elastane component. The proportion of polyamide in the elastic textile may be 50% or more, in particular between 50% and 60%. The proportion of elastane in the elastic textile may be 5% or more, in particular between 5% and 15%. The proportion of polyester in the elastic textile may be 40% or less, in particular between 30% and 40%.
[0034] According to a further aspect, a method for manufacturing trousers is presented. The method comprises providing tubular textile raw material, which includes elastic textile at least in an area corresponding to the seat area of trousers to be manufactured. The method further comprises slitting the raw material over a partial length of the raw material along a longitudinal axis of the raw material at at least two points spaced apart in a circumferential direction of the raw material to form two leg sections and a tubular hip section, wherein the leg sections extend from the hip section and the hip section at least partially encompasses the seat area, and sewing each of the leg sections together to form one leg of the trousers to be manufactured.The method further comprises attaching at least one reinforcing strip to an inside of the trousers to be manufactured, forming at least two attachment sections spaced apart from each other, such that the reinforcing strip spans the elastic textile in an area between the attachment sections without being attached, in such a way that, after attachment, the reinforcing strip reduces the elasticity of the trousers in the seat area between the attachment sections. Brief description of the drawing
[0035] Further features, advantages, and objectives become clear from the detailed description and the drawings. They show: Fig. 1 shows trousers according to an example, and Fig. 2 shows a method for making trousers according to an example. Detailed description of the revelation
[0036] Fig. 1Figure 1 schematically and exemplarily shows a pair of trousers 100, for example, leggings. A section of the trousers 100 is shown, corresponding to the seat area 102 of the trousers 100. The trousers 100 are elastic in the seat area 102. For this purpose, the trousers 100 comprise elastic textile, for example, elastic synthetic fabric. Fig. 1 shows the inside of trousers 100.
[0037] In the upper part of the shown section, the trousers 100 include a waistband 104 with a waistband seam 106. In the lower part of the shown section, an inseam 108 of the trousers 100 runs. In the example shown, the inseam 108 connects various edges of textile parts of the trousers 100 essentially along the inner thighs.
[0038] The trousers 100 also include a reinforcing strip 130. The reinforcing strip 130 has two mutually distinct fastening sections 132 and 134, by means of which the reinforcing strip 130 is attached to the inside of the trousers 100 with respect to the elastic textile. In an area B of the trousers 100, which extends between the fastening sections 132 and 134, the reinforcing strip 130 spans the elastic textile without being fastened.
[0039] By attaching the reinforcing pressure 130 to the elastic textile by means of the fastening sections 132, 134 and by appropriately dimensioning the length of the reinforcing tension 130 in the region B, the reinforcing tension 130 reduces the elasticity of the trousers 100 between the fastening sections 132, 134. In particular, the reinforcing tension 130 causes the elongation of the trousers 100 parallel to a spacing direction R of the fastening sections 132, 134 to be limited by the reinforcing tension 130 or inhibited due to the elastic modulus of the reinforcing tension 130.
[0040] The elastic textile is elastic in its plane of extension in the seat area 102 both parallel and perpendicular to the distance direction R of the fastening sections 132, 134. The reinforcing strip 130 is arranged such that it does not reduce, or at least not significantly reduces, the elasticity of the trousers 100 perpendicular to the distance direction R.
[0041] In the example shown, the fastening sections 132 and 134 are spaced apart from each other along the spacing direction R with respect to a median plane E, which corresponds to the crotch plane of the trousers 100. The reinforcing strip 130 extends along the median plane E. A longitudinal extension of the reinforcing strip 130 lies within the median plane E.
[0042] In the example shown, a first fastening section 132 is arranged at the waistband seam 106, and a second fastening section 134 is arranged at the inner seam 108. The arrangement of the fastening sections 132 and 134 at load-bearing connecting seams of the trousers 100, which are already provided on the trousers 100 due to manufacturing and / or structural requirements, independent of the reinforcing strip 130, enhances the stability of the trousers 100. Furthermore, this avoids the need for additional seams that would serve solely to attach the reinforcing strip 130 to the elastic fabric. This promotes a uniform appearance and greater design flexibility for the trousers 100.
[0043] In the example shown, area B extends between fastening sections 132 and 134 at the level of a hip plane H of the trousers 100. In conjunction with the foregoing, this allows the elastic textile along the hip plane H of some trousers 100 to be manufactured seamlessly, for example, by circular weaving and / or circular knitting. This also improves the uniform appearance of the trousers 100 in area B and adjacent areas.
[0044] In the example shown, the second fastening section 134, adjacent to a stitching of the reinforcing strip 130 to the inner seam 108, comprises a fastening seam 136 running parallel to the spacing direction R. The reinforcing strip 130 is sewn to the elastic textile along the length of the fastening seam 136. The area B, in which the reinforcing strip 130 extends unfastened over the elastic textile, is thus defined in its lower boundary by the length of the fastening seam 136.
[0045] The fastening seam 136, by appropriately selecting its length, allows the stretching behavior of the trousers 100 between the waistband seam 106 and the inseam 108 parallel to the center plane E to be influenced, as well as the adaptation of the trousers 100 to the body. In some examples, the fastening seam 136 is designed for this purpose such that, in an unstretched state of the reinforcing strip 130, the elastic textile is gathered in a region of the fastening seam 136 by means of the fastening seam 136.
[0046] In some examples, the relative length and position of area B according to a correspondingly chosen position and length of the fastening seam 136 is also chosen such that the wearing comfort of the trousers 100 is not or only slightly impaired by the reinforcement pull 130.
[0047] In an unstretched state of the reinforcing strip 130, the ratio between the length of the reinforcing strip 130 and the length of the fastening seam 136 of the trousers 100 is between 1.2 and 5, preferably between 1.4 and 3, preferably between 1.5 and 2.5.
[0048] In some examples, the length of the reinforcing tract 130 in an unstretched state is between 3 and 16 cm, preferably between 5 and 12 cm, preferably between 6 and 10 cm.
[0049] In some examples, the length of the reinforcing strip 130 corresponds at least substantially to a distance between the inner seam 108 and a first fastening section 132 of the at least two fastening sections 132, 134. In some of these examples, unlike the examples described above, the first fastening section 132 is not arranged at a waistband seam 106 of the trousers 100.
[0050] The previously described examples of the trousers (model 100) are particularly suitable for creating a scrunch effect. Compared to conventional scrunch leggings, these examples offer several advantages. In particular, scrunch leggings, as described above, allow for a uniform design in the hip area (H), especially along the midline (E). Thus, the trousers described above allow for the creation of a scrunch effect without altering the fabric or adding seams to the elastic material in this area. This improves the aesthetic appearance. Furthermore, potential limitations regarding the manufacturing and / or properties of the elastic material in the hip area can be avoided.
[0051] The use of tubular raw materials, such as circular-knitted or circular-woven textiles, for the production of trousers 100 is particularly advantageous. This is beneficial, for example, if the elastic textile incorporates one or more different structures that are uniformly present across a specific horizontal plane of the finished trousers 100 and vary along the height of the trousers 100.
[0052] Fig. 2 This shows a flowchart of a process 200 for manufacturing trousers, for example trousers 100.
[0053] Method 200 comprises providing tubular textile starting material, wherein the starting material comprises elastic textile at least in one area corresponding to a seat area of the trousers, step 210.
[0054] Method 200 further comprises slitting the starting material over a partial length of the starting material along a longitudinal axis of the starting material at at least two locations spaced apart in a circumferential direction of the starting material to form two leg parts and a tubular hip part, wherein the leg parts extend from the hip part and the hip part at least partially encompasses the buttocks area, step 220.
[0055] Procedure 200 further includes sewing each of the leg parts together to form one trouser leg of the trousers, step 230.
[0056] Method 200 further comprises attaching a reinforcing band to the inside of the trousers by forming at least two spaced-apart attachment sections such that the reinforcing band spans the elastic textile in an area between the attachment sections without being attached, step 240. The reinforcing band is attached in such a way that, after attachment, the reinforcing band reduces the elasticity of the trousers in the seat area between the attachment sections.
[0057] The techniques described above are presented in the context of trousers, particularly scrunch leggings. However, it is understood that these techniques can also be used in connection with other textile applications, especially other garments that are at least partially elastic, to achieve some or all of the described advantages.
