Abstract

A laminated fabric comprising: the fabric includes first and second fabric layers, first and second adhesive layers adhered to the first and second fabric layers, respectively, and an intermediate adhesive layer positioned between and adhered to the first and second adhesive layers. These layers are typically fused together in a hot press to produce an undergarment accessory such as a bra shoulder strap of good, extremely thin quality that is not apparent through the outer garment.

Description

laminated fabric

technical field

The utility model relates to a fabric which can be used for clothes. More particularly, although not exclusively, the present invention relates to a multi-ply laminate shoulder strap for a brassiere.

Background technique

Garment straps, known as shoulder straps in brassieres, are made by sewing one or two layers of fabric material together along longitudinal seams. Such belts may be uncomfortable to the wearer's skin and may have unsightly protrusions visible through garments. Also, a skilled seamstress must be employed to achieve a neat seam.

Utility model content

It is an object of the present invention to overcome or substantially ameliorate at least one of the aforementioned disadvantages, and/or more generally to provide an improved laminated fabric for clothing accessories.

The utility model discloses a laminated fabric, comprising:

first and second fabric layers,

first and second adhesive layers bonded to the first and second fabric layers, respectively, and

An intermediate adhesive layer positioned between and bonded to the first and second adhesive layers.

Preferably, the first and second fabric layers are synthetic.

Preferably, the first and second adhesive layers comprise thermoplastic polyurethane.

Preferably, the first and second adhesive layers each comprise a single sided adhesive film having adhesive adjacent to the respective fabric layer.

Preferably, the intermediate adhesive layer comprises a double-sided adhesive film.

Preferably, the intermediate layer comprises thermoplastic polyurethane.

Preferably, the first and second adhesive layers each have a thickness of about 0.025 mm.

Preferably, the thickness of the intermediate adhesive layer is about 0.1 mm.

The laminated fabrics described above are typically fused together at about 160°C.

Typically about 80 seconds are used to fuse the laminated fabrics together.

The laminated fabric of the present invention facilitates the provision of garment accessories of good quality, such as bra straps with a very thin profile that is not apparent through outer garments.

Description of drawings

Preferred forms of the utility model will now be described by way of example with reference to the accompanying drawings, wherein:

Figure 1 is a schematic perspective view of a bra with a pair of shoulder straps - an embodiment of the application of the laminated fabric disclosed in the present invention;

Figure 2 is a schematic partially exploded cross-sectional elevational view of a laminated fabric; and

Figure 3 is a schematic partially exploded perspective view of a laminated fabric.

Detailed ways

In Figure 1 of the accompanying drawings, a brassiere 10 having a pair of shoulder straps 11 is schematically depicted. This figure shows only one example of the application of laminated fabrics to be described below. Other embodiments may include: shoulder straps for vests and swimwear, waist belts for underwear and swimwear, and possibly outerwear.

The laminated fabric as shown in Figures 2 and 3 comprises five layers.

Layers 12 and 16 are each typically a synthetic fabric material, but may alternatively comprise a fabric material of natural fibers, such as cotton or linen. The fabric layer can be a woven fabric or a nonwoven fabric.

Adjacent to each fabric layer 12 and 16 is an adhesive layer 13 and 15, respectively. These layers may generally be single-sided adhesive films comprising TPU (thermoplastic polyurethane), with the adhesive side of each film facing the respective fabric layer 12 and 16 . Layers 13 and 15 are typically each about 0.025 mm thick. This thickness can of course vary according to the particular application of the laminated fabric.

Located between the adhesive layers 13 and 15 is an intermediate adhesive layer 14 . This layer may generally also comprise a TPU material, however in this case the intermediate adhesive layer is a double-sided adhesive film capable of being bonded to the non-adhesive backside of the adhesive layers 13 and 15 . The thickness of the intermediate adhesive layer is generally about 0.1 mm. Furthermore, the thickness can vary depending on the particular application.

Laminated fabrics are generally formed by taking a piece of fabric material and placing a piece of single sided adhesive film on it - thus forming a double layer; cutting said double layer into two parts, one being the layers 12 and 13 of the laminated fabric , while the other part is turned over to form the layers 15 and 16 of the laminated fabric; these layers are cut to the required size and shape; the middle layer is cut to the same size and shape alone or together with the preceding layers.

The layers configured as depicted in FIGS. 2 and 3 are then placed in a heated press and pressed at about 160° C. for about 80 seconds so that the bonded sides of the adhesive layers 13 and 15 are aligned with the respective fabric layers 12 and 16. The inner sides are bonded, and the intermediate layer 14 is bonded to the inward facing surfaces of the adhesive layers 13 and 15, respectively.

The ultrasonic cutter can then be used to laminate the fabric to make straps or other garment accessories. Use scissors to trim any excess material, if necessary.

It should be understood that modifications and changes obvious to those skilled in the art should not be regarded as beyond the scope of the present invention. For example, additional single-sided adhesive layers may be placed between layers 13, 15 and fabric layers 12, 16, respectively.
