Benefits of technology
"The invention is a new sealant that uses polyurethane and chloroprene to create a strong connection between two materials. This sealant is better than traditional stitching methods because it doesn't cause leaks or reduce the elasticity of the materials. It also has a high elasticity and can be adjusted for aesthetic purposes. Overall, this new sealant solves the problems of traditional stitching and creates a better connection between materials."
Problems solved by technology
The new sealant obviates the defects caused by stitching methods, namely penetrating sponge or fabric which causes leaks.
The normal used stitching method typically reduces the elasticity of the stitched sponges, even if the sponges are high elasticity or laminated with high elasticity fabric.

Embodiment Construction
[0022] Referring to the accompanying drawings including FIGS. 1 through 10, it will be seen that in FIG. 1 two wetsuit panels including one panel (1) made of a fabric laminated rubber sponge (5) and one panel (2) made of a non-laminated rubber sponge (5), are shown being aligned in adjacent relation. In FIG. 2 a process of gluing (4) is employed along the adjacent adjoining panel edges by applying a layer of glue (3). In FIG. 3, the two panels (1) and (2) are joined. FIG. 4 shows conventional stitching usually applied to the glued seam at the joinder of the two panels as is typical in the prior art.
[0023]FIG. 5 shows the applied new sealant (7, 8) instead of the conventional stitching to panels (1) and (2) along their adjoined seam. FIG. 6 shows the same use of the new sealant where identical non-laminated panels are joined.
[0024]FIGS. 7 and 8 illustrate two alternate processes for applying the inventive sealant to joined panels. In FIG. 7, a tank of liquid sealant feeds an applic...

Abstract
A wetsuit comprised of one-side laminated or the so-called skin panels of rubber sponges, sealed with a new sealant instead of normal stitching. The sealant can be solid or liquid depending on the material that will be sealed such as two cut panels sealed completely and without stitching. The new sealant structure, on opposing faces, enhances seam strength of the one-sided laminated wetsuit and can obviate blind-stitch and flat-stitch (or cover-stitch) on all seams assembled whether it's a one-sided or two-sided stitch. The normal blind-stitch or flat-stitch generates the needle holes that make the wetsuit end-users cold when the wetsuit is wet. The sewing thread also reduces both the flexibility and stretch of the wetsuit. The removal of stitches and the new sealant application make the wetsuit more watertight and flexible and improve aesthetics. The new sealant can be used on laminated rubber sponge wetsuit materials as well.
Description
CROSS-RELATED APPLICATIONS [0001] This application claims priority from Provisional Patent Application Ser. No. 60 / 691,463 filed Jun. 17, 2005.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to the field of wetsuits used for diving, surfing and the like and more specifically to an improved wetsuit comprised of one-sided laminated or the so-called skin panels or rubber sponges, sealed with a sealant instead of the normal stitching. The sealant can be solid or liquid depending on the material that will be sealed, such as two cut panels sealed completely and without stitching. [0004] 2. Background Art [0005] The conventional methods are at least one-sided stitches on the one-sided laminated or the so-called skin panels of the rubber sponges or they are non-stitch but it's limited to both-side laminated cut panels. Wetsuit end-users are not satisfied with the conventional wetsuits since penetrated needle holes bring in cold wat...
