The present disclosure relates generally to articles of clothing, and in particular, to an article of clothing having higher elasticity along a first direction as compared to a second direction at least in a section thereof.
Various garments, such as bras, T-shirts, pants, etc., incorporate elastic portions, for example around neck portion or in shoulder portion thereof. These elastic portions are capable of expanding and contracting, and thus may aid with supporting the garment against the body of a wearer. Conventionally, in order to allow for such expansion and contraction of the elastic portions, rubber material has been employed. Sometimes it is desired for the garments to have more elasticity along one direction as compared to another direction in order for the garment to fit the different sizes of different wearers. For instance, in trousers, a waist section usually needs enhanced elasticity along horizontal direction (or, the direction of stretching of the waist) as compared to vertical direction (or, the direction of length of the trouser), so as to make the trouser suitable for people of different body proportions.
Accordingly, there is a need of article of clothing with elastic portions which have higher elasticity along one direction as compared to other direction thereof, so as to make the article of clothing suitable for people of different body proportions.

Referring to the drawings,
In the present embodiments, the article of clothing 10 includes an elastic portion 100 disposed in at least one section of the body structure 12 thereof. The elastic portion 100 allows the body structure 12 to expand and contract for fitting the article of clothing 10 to the user. According to embodiments of the present disclosure, the elastic portion 100 has a higher elasticity along a first direction as compared to a second direction thereof, as discussed in the subsequent paragraphs. Such configuration may be required for making the article of clothing 10 suitable for wearers with different body proportions, while providing support to the wearer. In the present embodiments, the article of clothing 10 may have one or more elastic portions 100 disposed at one or more regions therein.
In the present examples, the fabric sheets 102a and 104a may be a product known by model number CMF-7440MU of Friendly Foundate Ltd. and having a make-up of approximately 80% Tactel and 20% Lycra, and a weight of about 190 g/sqm. Further, the foam sheets 102b and 104b are one of thermoplastic rubber (TPR), thermoplastic polyurethane (TPU), silicone, ethylene vinyl acetate (EVA), polyvinyl chloride (PVC) and polypropylene (PP). Preferably, the foam sheets 102b and 104b are of a polyurethane foam such as, for example, EL58-4S of Inoac Corporation which is a memory foam. In some examples, the fabric sheet and the foam sheet of the corresponding fabric layer may be laminated together using an adhesive, such as glue HM-1 of Forbo Swift Adhesives SA. The adhesive may be sprayed onto at least one of the opposing facing surfaces of the fabric sheet and the foam sheet. The adhesive may stick the fabric sheet and the foam sheet together when dry without heating, to form the corresponding first fabric layer 102 and the second fabric layer 104.
According to embodiments of the present disclosure, the elastic portion 100 further comprises an elastic mesh 106. The elastic mesh 106 is in the form of a net with plurality of openings therein. As illustrated, the elastic mesh 106 is sandwiched between the first fabric layer 102 and the second fabric layer 104 to complete the elastic portion 100. In one embodiment, the elastic mesh 106 is of the same dimensions as the first fabric layer 102 and the second fabric layer 104 such that the elastic mesh 106 is co-extensive (i.e. extends along entire surface areas) with the first fabric layer 102 and the second fabric layer 104. In other embodiment, the elastic mesh 106 may have smaller dimensions with respect to the first fabric layer 102 and the second fabric layer 104 such that the elastic mesh 106 extends only partially along surface areas of the first fabric layer 102 and the second fabric layer 104.
As discussed earlier, in the present embodiments, the elastic mesh 106 has higher elasticity along the first direction ‘A’ as compared to the second direction ‘B’ thereof. That is, in general, the elastic mesh 106 is more stretchable along one direction as compared to another direction along a plane of the elastic mesh 106. In one embodiment, the elastic mesh 106 has 1.1 to 3 times higher elasticity along the first direction ‘A’ as compared to the second direction ‘B’ thereof. In preferred embodiments, the elastic mesh 106 has about 2 to 3 times higher elasticity along the first direction ‘A’ as compared to the second direction ‘B’ thereof. In one or more embodiments, the first direction ‘A’ and the second direction ‘B’ are orthogonal to each other. In other examples, the first direction ‘A’ and the second direction ‘B’ may be disposed at an angle other than orthogonal to each other without any limitations. It may be appreciated that when the elastic portion 100 is utilized in the article of clothing 10, the first direction ‘A’ and the second direction ‘B’ of the elastic mesh 106 may be defined based on the orientation of the elastic portion 100 in the article of clothing 10.
As illustrated better in
According to one embodiment, the first threads 108 are made of higher elasticity material and the second threads 110 are made of comparatively lower elasticity material, thus imparting the elastic mesh 106 higher elasticity along the direction of extension of the first threads 108 (i.e. the first direction ‘A’) as compared to the direction of extension of the second threads 110 (i.e. the second direction ‘B’). In one example, the first threads 108 are made of thermoplastic elastomers (TPE) material and the second threads 110 are made of polyethylene (PE) material. It may be appreciated that any two elastic materials suitable to be formed as threads and for use in an article of clothing with relatively different elasticities can be utilized for forming the elastic mesh 106, as long as the material with comparatively higher elasticity is used for forming the first threads 108 and the material with comparatively lower elasticity is used for forming the second threads 110.
Herein, thermoplastic elastomers (TPE), also sometimes referred to as thermoplastic materials or thermoplastic rubbers (TPR), are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) which consist of materials with both thermoplastic and elastomeric properties. Thermoplastic materials show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic materials is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. Examples of thermoplastic materials which are widely available in the market include, but not limited to, Hytrel, Dryflex, Mediprene, Kraton, Pibiflex, Sofprene, Laprene, Sofprene, Dryflex, Santoprene, Termoton, Solprene, etc., to name a few. Further, polyethylene (PE) is a thermoplastic polymer with variable crystalline structure. Polyethylene is light, versatile synthetic resin made from the polymerization of ethylene. Polyethylene is commonly categorized into one of several major compounds of which the most common include LDPE, LLDPE, HDPE, and Ultrahigh Molecular Weight Polypropylene. Other variants include Medium Density Polyethylene (MDPE), Ultra-low-molecular-weight polyethylene (ULMWPE or PE-WAX), High-molecular-weight polyethylene (HMWPE), High-density cross-linked polyethylene (HDXLPE), Cross-linked polyethylene (PEX or XLPE), Very-low-density polyethylene (VLDPE), and Chlorinated polyethylene (CPE).
According to another embodiment, the first threads 108 have lower cross-sectional thickness as compared to the second threads 110. As may be contemplated, in such case, the first threads 108 would generally have lesser amount of material as compared to the second threads 110 in the elastic mesh 106, thus imparting the elastic mesh 106 higher elasticity along the direction of extension of the first threads 108 (i.e. the first direction ‘A’) as compared to the direction of extension of the second threads 110 (i.e. the second direction ‘B’). In one example, the second threads 110 have 1.1 to 3 times of cross-sectional thickness as compared to the first threads 108. In preferred examples, the second threads 110 have about 2 to 3 times of cross-sectional thickness as compared to the first threads 108.
According to yet another embodiment, the first threads 108 and the second threads 110 crisscross each other in a manner to form a plurality of rectangular openings 112 (as shown in
In an embodiment of the present disclosure, the fabric layers 102, 104 and the elastic mesh 106 are molded together using known heat molding techniques involving the application of heat and pressure to form the elastic portion 100. In one or more examples, the fabric layers 102, 104 and the elastic mesh 106 may be bonded or laminated during the molding process simply by the application of heat and pressure, or may additionally involve the use of an adhesive to facilitate bonding of the layers. The employed bonding techniques may depend largely on the nature of the fabric layers 102 and 104, e.g. leather, fabric, foam, etc. In one embodiment of the present disclosure, the first fabric layer 102, the second fabric layer 104 and the elastic mesh 106 are separately pre-molded and later joined together to form the elastic portion 100. The following paragraphs explain in detail the molding setup and processes for joining the fabric layers 102, 104 and the elastic mesh 106 together to form the elastic portion 100.
In an embodiment, the molding process involves hot pressing the elastic mesh 106 between the first fabric layer 102 and the second fabric layer 104. The hot pressing is carried out such that the elastic mesh 106 is heat sealed to at least one of the first fabric layer 102 and the second fabric layer 104. In one example, the hot pressing is carried out such that the elastic mesh 106 is heat sealed to both the first fabric layer 102 and the second fabric layer 104. Thereby, the elastic mesh 106 adheres the first fabric layer 102 to the second fabric layer 104. For this purpose, the fabric layers 102, 104 and the elastic mesh 106 are put together as a bundle between the molding parts 402 and 404, and pressed thereby. In other examples, the elastic mesh 106 is heat sealed to only one of the first fabric layer 102 and the second fabric layer 104. For this purpose, only one of the fabric layers 102 and 104 (i.e. either the first fabric layer 102 or the second fabric layer 104) and the elastic mesh 106 are put together between the molding parts 402 and 404 and pressed therein to obtain a molded assembly, and later the other of the first fabric layer 102 or the second fabric layer 104 is stitched or fastened by other suitable means, such as ultrasonic welding, to the obtained molded assembly. In such case, the other of the first fabric layer 102 or the second fabric layer 104 would stay loose in the elastic portion 100, as may be desired for some configurations of the article of clothing 10. It may be appreciated that the elastic mesh 106 also provides support to one or more of the first fabric layer 102 and the second fabric layer 104, and further prevents breaking of the first fabric layer 102 to the second fabric layer 104 during the molding process.
The presently disclosed elastic portion 100, with the elastic mesh 106 therein, allows the article of clothing 10 to expand and contract on application and removal, respectively, of force therefrom to make the article of clothing 10 suitable to worn by a person. The elastic portion 100 of the present disclosure can be utilized in any type of article of clothing, such as the article of clothing 10, which requires, at least in some section, more elasticity along one direction as compared to another direction. The more elastic direction corresponds to the location in the article of clothing 10 where it is desirable to have enhanced elasticity to fit the different sizes of different wearers. The less elastic direction corresponds to location in the article of clothing 10 where it is desirable to have relatively more support and stability. The implementation of elastic mesh 106 may provide desired directional elastic properties from the article of clothing 10, while possibly eliminating the need of using adhesives for securing the two fabric layers 102 and 104 in the elastic portion 100 thereof. The elastic mesh 106 in the elastic portion 100 also has the advantages of being light weight and cost-effective. Furthermore, the elastic mesh 106 with the plurality of openings, such as the plurality of rectangular openings 112, provides good ventilation in the elastic portion 100, and thereby in the section of the article of clothing 10 using the elastic portion 100. In some embodiments, the elastic portion 100 is a separate component from the rest of the article of clothing 10, and the elastic portion 100 is stitched or affixed by other suitable means, such as ultrasonic welding, to the rest of the article of clothing 10. In other embodiments, the first and second fabric layers 102, 104 are not separate from the rest of the article of clothing 10, and may span a part of or the whole of the dimensions of the article of clothing 10.
The foregoing descriptions of specific embodiments of the present disclosure have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present disclosure to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiment was chosen and described in order to best explain the principles of the present disclosure and its practical application, to thereby enable others skilled in the art to best utilize the present disclosure and various embodiments with various modifications as are suited to the particular use contemplated.
