Abstract: A wetsuit having an outer and/or inner surface is manufactured from an improved non-absorbent and quick drying fabric. The improved non-absorbent and quick drying fabric is made of 100% non-absorbent fiber, selected from polyester, having a fineness ranging from 30 denier to 75 denier, and pre-processed with water repellent before being knitted, then knitted by a single circular knitting machine under a setting of 18˜44 gauge per inch. The result is an improved fine, thin, non-absorbent, and quick drying fabric, which prevents the penetration of water molecules. The improved non-absorbent and quick drying fabric is laminated with a rubber sponge material to form an improved non-absorbent and quick drying wetsuit material.

Abstract: A life vest manufactured from an improved fabric, having a thickness ranging from 1.4 mm to 3.0 mm, and high elasticity provided by knitting with a double circular knitting machine under the setting of 20-28 gauges per inch. The improved thickness and high elasticity fabric is made of non-elastic yarns, selected from polyester, polyamide, or polypropylene, and from elastic yarns, of polyurethane. The combination of woven elastic and non-elastic yarns provides an intricate yet highly comfortable fabric which is soft and “furry” to the touch.

Abstract: An aquatic garment-heating device employs a conductive rubber-heating device, which obviates the troublesome wiring of the prior art heating devices. It also employs a wireless switch control, which provides a number of advantages. By using a wireless switch, the on/off mechanism for activating or deactivating the heater, may be worn on a diver's wrist where it can be readily located when needed without requiring wires hanging in inconvenient places. Moreover, because the wireless switch may be located in plain view, rather than hidden in a pocket for example, it may be implemented with meaningful visual devices to convey useful information about the status of the heater. For example, in the preferred embodiment, an observable light provides various different colors to indicate whether the heater is in a low, medium or high temperature condition. Finally, the present invention uses especially thin profile batteries and heating elements to preclude any discomfort for the user.

Abstract: A wetsuit fabric is knitted from fine denier, high count polyester yarn and fine denier, high elongation elastic yarn using a circular knitting machine under a high gauge setting, dyed and finished to form a high density wetsuit fabric. This fabric is laminated with a rubber sponge material to form an improved high elasticity polyester wetsuit fabric which is especially Velcro-hook resistant.

Abstract: An improved finishing method in the manufacture of wetsuits, can be used in the borders of collars, sleeves, and legs of a wetsuit. The inventive method includes the steps of melding fabric and rubber sponge using pressure and heat to make the fabric and rubber combine completely as one layer. The cutting of the border is neater without being covered with other material. The new method makes the wetsuit more elastic and the wetsuit wearer feels more comfortable.

Abstract: A wetsuit comprised of two layers of laminated rubber sponge material which may or may not be fabric coated. A stuffing material of variable thickness is located in selected areas between the two rubber sponges referred to herein as Air Chambers. The two layers of laminated rubber sponges are glued together along their adjacent surfaces except in selected areas where their common borders of the sponges are left unglued and form a watertight construction, i.e., the “Air Chamber”. The stuffing material is a light material with a density of 0.02˜0.05 mg/cm3 and typically formed of multi-layered fiber structure and the like. The Air Chamber can be located at any part of the wetsuit to provide the person who wears the wetsuit the function of heat retaining/thermal insulation and impact protection.

In an additional embodiment, the stuffing material is secured within another thin plastic enclosure within the air chamber. This enclosure may be provided as a single pocket or as a plurality of contiguous pockets.

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.

Abstract: An insulating member comprising a first nylon layer sandwiched between a first and second layer of neoprene. The member further comprises a second nylon layer attached to the second neoprene layer, such that the second neoprene layer is sandwiched between the first and second nylon layers. The method of binding the insulating member comprises threading a stitch from one side of the insulated member to penetrate the second nylon layer of a first insulated member and binding first neoprene layer of a second insulating member by threading the stitch through the first neoprene and nylon layer of the second member, wherein each stitch does not penetrate the second neoprene layer of each member.
