Description
Field of the Invention
The present invention relates to waders, and more particularly to waders and the method for manufacturing them.
Background of the Invention
A conventional pair of waders are shown in FIG. 6, and an illustration will follow in the detailed description of the preferred embodiments. The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional fishing trousers.
Summary of the Invention
In accordance with one aspect of the present invention, there is provided a pair of waders comprising a gas permeable layer including a first side and a second side, a water-proof film fixedly mounted on the first side of the gas permeable layer, an outer cover fixedly mounted on the water-proof film, and a lining fixedly mounted on the second side of the gas permeable layer.
In accordance with another aspect of the present invention, there is provided a method for manufacturing a pair of waders and comprising the steps of: (a) providing a lining, a gas permeable layer including a first side and a second side, a water-proof film, and an outer cover; (b) forming a plurality of vent holes through the gas permeable layer; (c) mounting the water-proof film on the first side of the gas permeable layer; (d) mounting the outer cover on the water-proof film; (e) mounting the lining on the second side of the gas permeable layer to form a laminated layer including the lining, the gas permeable layer, the water-proof film and the outer cover; (f) cutting the laminated layer so as to form a plurality of peripheral cut edges; (g) adhering the peripheral cut-edges of the laminated layer to form a semi-product of a pair of waders; and (h) sewing up the peripheral cut-edges of the laminated layer to form a product of the pair of waders.
Further features of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

Detailed Description of the Preferred Embodiments
For a better understanding of features and benefits of the present invention, reference is now made to FIG. 6, illustrating a conventional pair of waders 50 in accordance with the prior art. The conventional waders 50 are water-proof and can be adapted to suit a fisherman, a yachtsman, etc, thereby preventing the wearer's trunk and legs from getting wet. However, the conventional waders 50 are impermeable to gas such that they cannot provide a ventilating effect to the wearer, thereby easily causing an uncomfortable sensation due to moisture accumulating therein. In addition, the conventional waders 50 are heavy, thereby causing an inconvenience to the wearer.
Referring to the remaining drawings, and initially to FIGS. 2-4, a pair of waders 1 according to the present invention comprises a gas permeable layer 20 including a first side and a second side, a water-proof film 30 fixedly mounted on the first side of the gas permeable layer 20, an outer cover 40 fixedly mounted on the water-proof film 30, and a lining 10 fixedly mounted on the second side of the gas permeable layer 20.
The gas permeable layer 20 is made of foamable material or synthetic rubber and defines a plurality of vent holes 21 therethrough. The water-proof film 30 is preferably made of polyurethane (P.U.). The outer cover 40 and the lining 10 are made of nylon cloth respectively.
In operation, a person can put on the waders 1 with the lining 10 directly contacting or her skin and with the outer cover 40 exposed to surroundings. In such a manner, the gas permeable layer 20 can be adapted to provide a ventilating effect to the wearer by means of the vent holes 21, thereby incurring a comfortable sensation.
In addition, the water-proof film 30 can be adapted to efficiently to prevent water from entering and wetting the lining 10 via the vent holes 21, thereby achieving a water-proof function.
Referring now to FIGS. 1-5, a method in accordance with the present invention can be adapted for manufacturing a pair of waders 1 and comprises the following steps.
First of all, the lining 10, the gas permeable layer 20 including the first side and a second side, the water-proof film 30, and the outer cover 40 are initially selected, wherein the gas permeable layer 20 is made of foamable material or synthetic rubber, the water-proof film 30 is made of polyurethane (P.U.), the outer cover 40 and the lining 10 are made of nylon cloth respectively.
Secondly, the plurality of vent holes 21 is defined through the gas permeable layer 20 by means of such as a punching machine. Then, the water-proof film 30 can be mounted on the first side of the gas permeable layer 20 by means of such as adhesion.
Preferably, the gas permeable layer 20 together with the water-proof film 30 can be conveyed to be heated and pressurized between a pair of heating rolls 60 as shown in FIG. 5 such that the water-proof film 30 can be tightly adhered on the first side of the gas permeable layer 20. The heating temperature for heating the gas permeable layer 20 together with the water-proof film 30 ranges between 110.degree. C. and 130.degree. C.
Then, the outer cover 40 can be mounted on the water-proof film 30 by means of such as adhesion, and the lining 10 can be mounted on the second side of the gas permeable layer 20 by means of such as adhesion, thereby forming a laminated layer including the lining 10, the gas permeable layer 20, the water-proof film 30 and the outer cover 40.
The laminated layer can then be cut according to the shape of the waders 1 so as to form a plurality of peripheral cut edges. The peripheral cut edges of the laminating layer can then be adhered together to form a semi-product of the waders 1.
Finally, the peripheral cut edges of the laminated layer can be sewed, thereby forming a product of the pair of waders 1 as shown in FIG. 4.
It should be clear to those skilled in the art that further embodiments may be made without departing from the scope and spirit of the present invention.
