Description

ARTCLE OF CLOTHING AND MANUFACTURING METHOD THEREOF

FIELD OF THE PRESENT DISCLOSURE

The present disclosure relates generally to articles of clothing, and in particular, to an article of clothing having one or more elastic portions to allow for expansion and contraction thereof.

BACKGROUND

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. The rubber material is often sewn or adhered to the portions of the garments that are to be made elastic. To wear or remove the garment, force is applied to the elastic portions, and the rubber material allows the elastic portions to expand to moderate elongations. Once the applied force to the elastic portions is removed, the rubber material causes the elastic portions to regain their original shape from the expanded state, thus providing a snug fit against the body of the wearer.

However, typical rubber material tends to lose its elastic properties after repeated stretching over a period of time. Once the rubber material losses its elastic properties, the elastic portions of the garment be likely to get loose, with limited or no expanding and contracting capabilities. Therefore, the garment after multiple uses may not be able to provide consistent expansion and/or contraction as desired by the wearer. Such garments often become unfit to be used, unless the rubber material is replaced with a new rubber material. Further, these garments utilizing rubber material for providing elasticity are prone to yellowing. Some garments may utilize thermoplastic materials which provide better elastic properties compared to traditional rubber. However, if such garments are subjected to high temperatures, such as high temperature washing and pressing or ironing, they may lose their elastic properties.

Accordingly, there is a need of article of clothing with elastic portions which can retain elastic properties even after repeated and prolonged usage, and can withstand high temperatures, leading to an increase in overall life span of the garments.

Referring to the accompanied drawings, FIG. 1 illustrates a diagrammatic view an article of clothing (generally referred by the numeral 100) , in accordance with one or more embodiments of the present disclosure. In the present illustration, the article of clothing 100 has been shown to be a brassiere; however, for the purposes of the present disclosure, the article of clothing 100 may be any garment to be worn by a wearer. For example, the article of clothing 100 may be, but not limited to, a bra top, a sports top, a pantie, a T-shirt, a pant, and the like. The article of clothing 100 includes a body structure 102 which defines shape and purpose of the article of clothing 100. In the exemplary article of clothing 100 of FIG. 1, the body structure 102 includes a pair of bra cups, with a first bra cup 104a and a second bra cup 104b. A center gore 106 is extending between and connects the first bra cup 104a and the second bra cup 104b. A pair of straps, including a first strap 108a and a second strap 108b are attached to peripheries of the first bra cup 104a and the second bra cup 104b, respectively. Further, a pair of side wings, including a first side wing 110a and a second side wing 110b are attached to the peripheries of the first bra cup 104a and the second bra cup 104b, respectively. In one or more examples, one or more fasteners 112 may be provided with one or more of the first side wing 110a and the second side wing 110b. It may be contemplated that the pair of

straps

108a and 108b support the article of clothing 100 on shoulders of the wearer, while the pair of

side wings

110a and 110b support the article of clothing 100 around a torso of the wearer. In some examples, the pair of

straps

108a and 108b may not be provided and only the pair of

side wings

110a and 110b may support the article of clothing 100 on the wearer.

As illustrated in FIG. 1, the body structure 102 provides one or more edges, including an edge 114. In the illustrated examples, the edge 114 is shown to be extending along a bottom of one or both of the pair of

side wings

110a and 110b of the body structure 102, in the article of clothing 100. For such cases, the edge 114 has been, sometimes, interchangeably referred to as “bottom edge 114” without any limitations. It may be understood that although the edge 114 is shown to be extending along the bottom of the body structure 102; in other examples, the edge 114 may be any other edge, such as, a side edge or a top edge, of the body structure 102 without any limitations. According to an embodiment of the present disclosure, the article of clothing 100 includes an elastic portion 120 formed along and co-extensive with the edge 114 of the body structure 102. The elastic portion 120 may be extending along the entire length of the edge 114 of the body structure 102. In some examples, the article of clothing 100 may have multiple elastic portions 120 formed along various edges thereof. Herein, the elastic portion 120 allows the article of clothing 100 to expand and contract. It may be understood that the body structure 102 provides the external appearance to the article of clothing 100 and the incorporated elastic portions 120 allow the article of clothing 100 to be worn and removed conveniently.

FIG. 2 illustrates one of the side wings, for example side wing 110a of the article of clothing 100; and FIG. 3 illustrates a section view of the side wing 110a taken along the section AA’ as shown in FIG. 2. As depicted, the article of clothing 100, or particularly the side wing 110a therein, includes a first fabric layer 122 and a second fabric layer 124. Herein, the first fabric layer 122 and the second fabric layer 124 are portions of a single panel 126 which is a single piece, hereinafter referred to as “first panel. ” In one embodiment, as illustrated, the first fabric layer 122 and the second fabric layer 124 are defined by folding of the first panel 126. In the illustrated example, the first panel 126 is folded once at fold 128a to define the first fabric layer 122 and the second fabric layer 124, and is further folded at fold 128b to be joined back to the first fabric layer 122. In another example (not illustrated) , the first fabric layer 122 and the second fabric layer 124 may be separate pieces and placed as one on the other to define two layers of the first panel 126. In general, the second fabric layer 124 in the present example is disposed below the first fabric layer 122. Herein, the first fabric layer 122 has an inner surface 122a and an outer surface 122b; and also the second fabric layer 124 has an inner surface 124a and an outer surface 124b. In the present configuration of the first panel 126, the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124 are facing each other.

According to an embodiment, the article of clothing 100, or herein the first panel 126, includes a silicone layer 140 embedded with at least one of the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124. In the present example, the silicone layer 140 is embedded with at least one of the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124 at or near the fold 128a. As shown, the silicone layer 140 is sandwiched between the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124. In particular, the silicone layer 140 is embedded with the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124; i.e., the silicone layer 140 is embedded with the textile material of the first fabric layer 122 and the second fabric layer 124. Herein, the silicone layer 140 provides the elasticity to the first panel 126 at or near the fold 128a. The silicone layer 140 further acts as the adhesive, and thereby the silicone layer 140 joins the first fabric layer 122 and the second fabric layer 124 at or near the fold 128a, without the need of or in the absence of any additional adhesive. In an embodiment, the first panel 126 is provided with a layer 142 of adhesive for joining the loose edges of the first panel at the fold 128b. In some other embodiments, the layer 142 provided at the other fold 128b may also be a silicone layer, in place of the adhesive layer, with the silicone layer 142 acting as the adhesive.

The present disclosure further provides a method of manufacturing the article of clothing 100, or a part or a component of the article of clothing 100, such as the side wing 110a as illustrated in FIG. 3. Herein, the method includes providing the first panel 126. As illustrated in FIG. 4, the first panel 126 is in the form of a piece of suitable textile material. Herein, the first panel 126 is laid flat on a flat surface, such as the flat surface 144. The method further includes placing a template 146 onto the first panel 126. The template 146 includes a cut-out 148 formed in the required shape of the silicone layer to be formed. The template 146 is placed onto the first panel 126. As discussed above, the first panel 126 is folded to define the first fabric layer and the second fabric layer. Thus, the template 146 can be considered to be placed on one of the following: the inner surface of the first fabric layer and the inner surface of the second fabric layer.

The method further includes pouring silicone material into the cut-out 148 of the template 146. The silicone material is poured or applied manually or by machine in liquid form or gel form. In some embodiments, the silicone material is prepared by mixing two components, a first component and a second component, with the first component preferably including one or more of hydrogenated silicone oil, additives and catalysts, and the second component preferably including one or more of vinyl silicone oil and silica. In some examples, the silicone material may be Polysiloxane rubber (SiR) , as known in the art. Further, as illustrated in FIG. 5, the method further includes scrapping the extra poured silicone material from the cut-out 148 of the template 146, to form the silicone layer in the shape of the cut-out 148. As shown, the scrapping of the extra poured silicone material may be done by using a knife 150 or the like. Thereafter, the template 146 may be removed, to leave a layer of silicone material on the first panel 126.

Subsequently, as illustrated in FIG. 6, the first panel 126 is folded to define the first fabric layer and the second fabric layer, with the first fabric layer having an inner surface and an outer surface and the second fabric layer having an inner surface and an outer surface, as discussed above. As shown better in FIG. 7, the layer of silicone material is disposed between the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124. Herein, the layer of silicone material is substantially embedded with the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124.

As illustrated in FIG. 8, the method further includes pressing the first fabric layer 122 and the second fabric layer 124 together, thereby forming the silicone layer 140 embedded with the inner surface 122a of the first fabric layer 122 and the inner surface 134a of the second fabric layer 124. In this step, the first fabric layer 122 and the second fabric layer 124 are joined together by pressing, using a press 152. In one example, the first fabric layer 122 and the second fabric layer 124 are pressed together at room temperature. In another example, the first fabric layer 122 and the second fabric layer 124 are hot-pressed together. It will be appreciated that the pressing together of the first fabric layer 122 and the second fabric layer 124 generally occurs before curing of the silicone material therebetween, and forming of the silicone layer 140 as described above. The silicone material is allowed to cure at room temperature or under heat in a drying oven. The silicone material is cured at a temperature in the range of 50 to 150 degree Celsius. The method further comprises curing the silicone material for a period in the range of 5 to 60 minutes. As may be appreciated, longer curing time will be required if curing is at room temperature. Further, actual curing time will also depend on the thickness of the silicone layer to be formed. Typical thickness of the silicone layer to be formed is 0.1 to 1.5 mm.

During the curing process, the silicone material will penetrate into the fabric, and upon curing and pressing the outer and inner layers of the fabric enclosing the silicone layer Thus, the layers will be adhered to each other, without the need of an adhesive. FIG. 9 illustrates an exemplary first panel 126 as formed with the silicone layer 140 embedded with the inner surface 122a of the first fabric layer 122 and the inner surface 134a of the second fabric layer 124 therein. FIGS. 10-16 illustrate other possible configurations of the first panel 126 that could be formed by the method as described above in reference to FIGS. 4-8. In some examples, the article of clothing 100 further includes a second panel, such as a back panel in the brassiere (not shown) . In such example, the first panel and the second panel are joined together.

FIG. 10 illustrates an arrangement 1000 of the various layers for forming the first panel 126 when pressed, in accordance with an embodiment of the present disclosure. As shown in FIG. 10, the first fabric layer 122 and the second fabric layer 124 are portions of a fabric sheet, and are defined by folding of the fabric sheet along a folded region 1002. Also as may be seen, the fabric sheet is further folded along a folded region 1004, such that the inner surface 122a of the first fabric layer 122 is facing the outer surface 124b of the second fabric layer 124 at their respective

free ends

1006a and 1006b. The silicone layer 140 is disposed proximal to the folded region 1002 between the inner surface 122a of the first fabric layer 122 and the inner surface 124a of the second fabric layer 124. Further, an adhesive layer 1008 is provided proximal to the folded region 1004 between the inner surface 122a of the first fabric layer 122 and the outer surface 124b of the second fabric layer 124. In some examples, the layer 1008 provided at the fold 1004 may also be a silicone layer in place of the adhesive layer, with the silicone layer 1008 acting as the adhesive.

As can be seen, the two zones have different thicknesses. In the exemplary embodiment as shown, the first zone 4102 has a thickness that is greater than the thickness of the second zone 4112. The thicker first zone 4102 provides better support and stronger resilient force than the thinner second zone 4112, and is generally disposed at regions where support or enhanced support is required. For example, as shown in FIG. 41 and FIG. 42, the first zone 4102 is disposed along an edge of the article of clothing, or an edge of the side wing of the brassiere 100. The second zone 4112 can be disposed at any other parts of the article of clothing or any other parts of the side wing of the brassiere 100. In the exemplary embodiment as shown, the second zone 4112 is disposed further away from the edge than the first zone 4102. It will be appreciated that it is not necessary that the first zone is disposed along an edge; it can be disposed at any part of the article of clothing as desired.

FIG. 43 illustrates the

side wing

110a or 110b of the brassiere 100 of FIG. 1 in accordance with another embodiment. FIG. 44 illustrates a section view of the side wing taken along a section FF’ as shown in FIG. 43. In the exemplary embodiment as shown in FIG. 43 and FIG. 44, the silicone layer comprises two zones, namely a first zone 4302 and a second zone 4312. The first zone 4302 has a thickness that is greater than the thickness of the second zone 4312. In addition, in the exemplary embodiment as shown, the second zone 4312 comprises or is applied in a pattern with a plurality of openings, each opening defining a region of absence of silicone. The other regions of the pattern, i.e., regions other than the openings, are where silicone is present. The openings as shown in FIG. 43 and FIG. 44 are of diamond shape. However, any suitable shape may be utilized, such as circular, oval, rhombus or any other suitable shape. Also, any suitable pattern may be utilized that facilitates an adequate bonding between the inner layer and the outer layer or between the first fabric layer and the second fabric layer, and also provide desired air permeability and stretchability. The pattern may be a repeating pattern, or may be an irregular pattern.

In the embodiments as shown in FIG. 41 to FIG. 44, the first zone and/or the second zone can be of any suitable shape. For example, it can be of strip shape, wave shape, dot shape, mesh shape, or any other suitable shape.

In manufacturing, silicone layer may be applied in a pattern through, for example, screen printing technique. Silicone layer comprising two or more zones of different thicknesses may be applied using suitable mold. Alternatively, silicone layer comprising two or more zones of different thicknesses may be applied through repeating two or more times the following steps to produce the thicker zone or zones: placing template on the fabric layer, pouring silicone material into the cut-out of the template corresponding to the thicker zone or zones, scrapping the extra poured silicone material from the cut-out of the template and allowing the silicone material to cure; and followed by pressing the first fabric layer and the second fabric layer together to thereby form the silicone layer that is embedded with at least one of the inner surface of the first fabric layer and the inner surface of the second fabric layer and join the first fabric layer and the second fabric layer.

In general, typical thickness of the silicone layer according to the present disclosure is 0.1 to 1.5 mm. Where there are, for example, two zones of the silicone layer with different thicknesses, typical thickness of the first zone which has a greater thickness is 0.35 to 0.6 mm, while typical thickness of the second zone which has a smaller thickness is 0.15 to 0.35 mm.

Although some of the embodiments described in the foregoing are related to side wings or brassieres, it will be appreciated that the features and concepts described are applicable to any article of clothing, including but not limited to a brassiere, a sports bra, an undergarment, a sports pant, a sportswear, a casual dress, and a T-shirt.

The silicone layer as formed provides the one or more elastic portions in the various articles of clothing as described above. After curing, the silicone layer is resistant to high temperature and hence the assembly of outer and inner layers enclosing silicone (or elastic portion) could be subject to hot pressing or hot molding, for example to produce the there-dimensional cup shape. The shape of the cured silicone layer, and hence the part providing adhering and elastic recovery properties, is defined by the template, and can be adjusted to suit any required shape. The silicone layer is preferably planar, but may also be curved depending on the template. It may be appreciated that by appropriately choosing the composition making up the silicone material, the hardness and softness of the silicone layer (formed after curing) can be controlled and so it can also be applied so as to provide support in regions requiring support, such as the lower region below the two cup regions as illustrated in FIG. 30.

The embodiments and methods described in the foregoing focused on the use of a silicone layer being embedded with at least one of the inner surface of the first fabric layer and the inner surface of the second fabric layer, and thereby joining the first fabric layer and the second fabric layer. Apart from using silicone, the following may also be used: silicone rubber, natural rubber adhesive, polyamide resin adhesive, or 1-component-polyurethane adhesive.

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.
