Abstract
A method for producing a series of trousers is provided. A fabric having a fabric stretch, as measured in accordance with Active Standard ASTM D3107, of at least 85, is provided. Patterns for a plurality of sizes of the trousers are provided, where each size covers at least three standard sizes. The fabric is cut in accordance with the patterns, thereby obtaining a plurality of trouser cuttings, and trousers in various sizes are manufactured from the trouser cuttings. The method according to the invention reduces waste in textile manufacturing.
Description
- The present invention relates to a method for producing a series of trousers. The method according to the invention reduces waste related to textile production.
- When designing clothes, such as trousers, it is common to design a number of different sizes for a given style, in order to ensure that the style can fit a wide variety of persons. The various sizes are then produced in batches in such a manner that it is attempted to match an expected demand from consumers. On the one hand, it should be ensured that a specific size is available for a consumer requesting so, and on the other hand it should be ensured that an excessive surplus of some sizes is avoided.
- Since a manufacturer would often rather meet the demands of the consumers than not, the balancing between the two concerns described above often leads to a surplus of produced garments, which are destroyed, often burned, when a new collection enters the market. This constitutes a very undesired waste of textiles. This problem is particularly pronounced for very large and very small sizes, which are in lower demand than the intermediate sizes.
- Furthermore, a person who has acquired a garment may change size in such a manner that the garment no longer fits, before the garment is worn out. This could, e.g., be the case in case of weight loss or weight gain, or due to children growing. In such cases the garment will most likely also be discarded, and thereby destroyed, even though the garment is not worn out.
- It is an object of embodiments of the invention to provide a method for producing a series of trousers which allows a reduction of waste related to textile production.
- It is a further object of embodiments of the invention to provide a method for producing a series of trousers which improves sustainability.
- The invention provides a method for producing a series of trousers, the method comprising the steps of:
- providing a fabric having a fabric stretch, as measured in accordance with Active Standard ASTM D3107, of at least 85,
- providing patterns for a plurality of sizes of the trousers, where each size covers at least three standard sizes,
- cutting the fabric in accordance with the patterns, thereby obtaining a plurality of trouser cuttings, and
- manufacturing trousers in various sizes from the trouser cuttings.
- Thus, the invention provides a method for producing a series of trousers. In the present context the term 'series of trousers' should be interpreted to mean a style or design, in the form of a pair of trousers, which is produced in a number of different sizes.
- According to the method, a fabric is initially provided. The fabric has a fabric stretch of at least 85, as measured in accordance with Active Standard ASTM D3107. This is a standard test which is used for determining the stretch, growth and recovery properties that garments made with the tested fabric may be expected to exhibit during use. The test is particularly suitable for fabrics woven in whole or in part from stretch yarns, and which exhibit high stretch and good recovery properties from low tension. Further information regarding the Active Standard ASTM D3107 can be found at: https://www.astm.org/Standards/D3107.htm.
- Accordingly, the provided fabric has a high fabric stretch, and may advantageously be a fabric which is woven in whole or in part from stretch yarns.
- Next, patterns for a plurality of sizes of the trousers are provided. Each of the sizes covers at least three standard sizes. Thereby the number of different sizes produced can be reduced by at least 2/3, without reducing the number of standard sizes covered by the series of trousers. This will be described in further detail below.
- Finally, the fabric is cut in accordance with the patterns, thereby obtaining a plurality of trouser cuttings, and trousers in various sizes are manufactured from the trouser cuttings, thereby producing the series of trousers.
- As described above, the series of trousers manufactured in this manner covers a high number of standard sizes with a number of sizes which is at most 1/3 of the number of standard sizes covered. This is partly possible due to the high fabric stretch of the applied fabric, which allows the trousers to stretch and recover, thereby matching several sizes.
- Since each of the sizes covers at least three standard sizes, the surplus of produced items required in order to meet customer demands can be reduced, because a given size will meet the demand of customers which would normally require at least three different sizes. In particular, the very small and very large normal sizes are covered by sizes which also cover more intermediate sizes, which are in higher demand. This significantly reduces the need for destroying unsold items, thereby reducing waste of textile products and improving sustainability.
- Furthermore, if an owner of a specific pair of trousers increases or decreases a single standard size, the trousers will most likely still fit, because the size covers at least three standard sizes. This increases the likelihood that the owner will wear and use the trousers until they are worn out, rather than discarding them because they no longer fit. This also significantly reduces waste of textile products and improves sustainability.
- The method according to the invention is particularly relevant with respect to garments for children and maternity clothes, but it is also relevant for ordinary garments for adults.
- The fabric may have a fabric stretch, as measured in accordance with Active Standard ASTM D3107, within the interval 85 to 95, such as within the interval 87 to 93, such as within the interval 90 to 92, such as approximately 91. According to one embodiment, the fabric stretch may be approximately 91.2±4%.
- The step of providing patterns for a plurality of sizes may comprise providing patterns for at most six adult sizes.
- According to this embodiment, a high number of standard adult sizes are covered by at most six adult sizes of the kind provided by the invention. Thus, if the patterns define six adult sizes, and each of these adult sizes covers at least three standard sizes, then at least eighteen standard sizes will be covered by only six sizes. This significantly reduces the waste of textile products.
- The step of providing patterns for a plurality of sizes of trousers may comprise providing patterns, where each size covers at least three European standard sizes.
- According to this embodiment, the standard sizes covered by the inventive sizes are European standard sizes, such as European standard adult sizes. As an alternative, the standard sizes could be US standard sizes, UK standard sizes, standard children sizes, or any other suitable kind of standard sizes.
- The plurality of sizes may in combination cover sizes of at least European
standard size 34 to Europeanstandard size 56. - These are the most commonly used standard sizes in Europe, and collections covering this span of sizes would normally include, by far, most of the demand of the market.
- According to this embodiment, a size I may cover European
standard sizes standard sizes standard sizes standard sizes - Thereby European
standard size 34, which is normally not in high demand, is covered by a size, i.e. size I, which also covers the morecommon sizes - Similarly, European
standard size 56 is covered by a size, i.e. size IIII, which also coverssizes - The fabric may be a denim fabric. Denim fabric is known to be durable, and it is therefore suitable for producing trousers. Alternatively, the fabric may be of any other suitable kind which meets the requirements with regard to fabric stretch.
- The invention will now be described in further detail with reference to the accompanying drawings in which

It can be seen fromFigs. 1-4 that each of the sizes I-IIII covers three European standard sizes. - It can be seen from
Fig. 1-4 , that size I covers Europeanstandard sizes standard sizes standard sizes standard sizes - Thus, by the series of
trousers 1 illustrated inFigs. 1-4 , European standard sizes 34-56 are covered by only four sizes, i.e. sizes I-IIII. As described above, this reduces the risk that surplus garments need to be discarded due to low demand from consumers. -
