Benefits of technology

The present invention relates to garments or garment panels with a functional layer, an inner textile layer, and a discontinuous adhesive layer that affixes the inner textile layer to the functional layer. The inner textile layer comprises a plurality of dissimilar textile pieces that can be abutted or have at least portions of contact with each other. The garment or garment panel can also have an outer textile layer affixed to the second side of the functional layer. The invention provides a method of making a garment construct by affixing an inner textile layer to a functional layer and then adding an outer textile layer to create an outer shell or bond shell material. The garment constructs are assembled via seams to form a finished garment. The technical effects of the invention include creating garments or garment panels with a unique pattern and texture, improved comfort, and enhanced durability.

Problems solved by technology

However, air gaps between the outer layer and the waterproof lining reduce water vapor permeability and heat transmission.
Thus, the lining side of these garments contains a large number of seam sealing tapes which are unattractive, create friction upon contact with the body and can become detached upon rubbing against the body.

example 1

[0057]A seamless garment or garment panel having a liner layer with a plurality of dissimilar textiles with varying moisture vapor permeability was formed in the following manner:

[0058]A two-layer textile laminate was formed comprising a composite barrier membrane as the functional layer laminated to a textile layer. In this exemplary embodiment, the composite barrier membrane was a composite of microporous polytetrafluoroethylene (PTFE) membrane coated with a polyurethane, prepared according to U.S. Pat. No. 4,194,041 using a water vapor permeable, nonporous polyurethane coating on the ePTFE. This membrane was laminated on one side, using a plurality of dots of moisture curable polyurethane adhesive, to a polyester woven textile layer approximately 0.4 mm thick and having a weight of approximately 100 grams per square meter. The other side of the membrane was coated with a discontinuous thermoplastic polyurethane adhesive 10 using a plurality of dots. A first panel having rough dim...

example 2

[0063]A seamless garment or garment panel having a liner layer with a plurality of dissimilar textiles with varying moisture vapor permeability, a functional layer 7 comprising a composite membrane barrier, and a sealing region was formed in a manner substantially as described in Example 1, with the following exceptions:

[0064]The second panel was formed with approximate dimensions of 0.289 m by 0.283 m.

[0065]The third panel was formed with approximate dimensions of 0.289 m by 0.283 m.

[0066]The fourth panel consisting of two discrete textile regions was disposed on the thermoplastic adhesive 10 side of the first textile laminate panel such that the edges of the first and fourth panel were not coincident. Specifically, the edges of the fourth panel were 17 mm from the edges of the first panel, leaving an exposed region of the composite barrier membrane of the first panel 17 mm wide around the perimeter of the bonded panel, referred to herein as the sealing region. Each textile region ...

example 3

[0067]A waterproof seam was formed between two garment constructs having liner layers with a plurality of dissimilar textiles of varying moisture vapor permeability in the following manner:

[0068]Two seamless garment constructs, each having a plurality of dissimilar textiles of varying moisture vapor permeability and a functional layer 7 comprising a composite membrane barrier were formed by the method described in Example 2.

[0069]The textile laminate panels were then joined at one of their respective sealing regions by sewing in a straight line, 6 mm from the panel edge, using a Juki sewing machine (Model No. DLN-415-5, Juki Corporation, Tokyo, Japan), set to 5.1 stitches per cm, followed by trimming of 4 mm off the seam allowance to ensure that the edge of the resultant 2 mm seam allowance was at least 4 mm from the edge of the textile laminate panels in either of the non-sealing regions.

[0070]A 22 mm width seam tape (GORE SEAM® seam tape obtained from W.L. Gore and Associates, Elk...

Abstract

Garment constructs and garments prepared therefrom having a functional layer and an inner layer of a plurality of textiles, at least two of which are dissimilar textiles, adhered to the functional layer are provided.

Description

FIELD OF THE INVENTION[0001]This invention relates to garment constructs and garments prepared therefrom having a functional layer and an inner layer formed of a plurality of textiles, at least two of which are dissimilar textiles, adhered to the functional layer. In some embodiments, the garment constructs or garments prepared therefrom have an outer layer adhered to the side of the functional layer opposite to the inner layer.BACKGROUND OF THE INVENTION[0002]Garments have been described having an outer protective layer ordinarily permeable to liquid water and a waterproof breathable layer affixed inside the outer layer. Optionally, these constructs are provided with an adjacent, but not affixed, inner liner textile.[0003]Garments have also been constructed using a waterproof lining, generally formed from pattern pieces cut out of sheets and then joined together at seams, typically by sewing. This lining is generally loosely disposed against the inner side of the outer layer. Howev...
