DETAILED DESCRIPTION

(11) The present disclosure describes water-tight sealing sleeves suitable for use in the neck, wrist, ankle, and/or other openings of waterproof garments, as well as waterproof garments including such sealing sleeves.

(12) Examples of waterproof garments including the sealing sleeves 30, 40 are shown in FIGS. 1 and 2. FIG. 1 shows a waterproof smock intended for sailing. FIG. 2 shows a waterproof dry suit commonly used for sailing as well as many other aquatic activities. The waterproof garments are generally made from a waterproof textile 1 joined at seams 2 by a waterproof hot-melt adhesive seam tape or other method known in the art. The waterproof garments feature a neck sealing sleeve 30 joined to a neck opening 3 to provide a water-tight seal around the wearer's neck, and wrist sealing sleeves 40 joined to wrist openings 4 to form water-tight seals around the wearer's wrists.

(13) The waterproof textile 1 generally has limited stretch. The neck opening 3 is generally sized to be larger than the wearer's head, allowing the head to fit through the neck opening 3. The wrist opening 4 is generally sized to be larger than the wearer's hand, allowing the hand to fit through the wrist opening 3. The neck sealing sleeve 30 and the wrist sealing sleeves 40 are each provided in a tubular shape. The neck sealing sleeve 30 and wrist sealing sleeves 40 have respective first openings 31, 41 (see FIGS. 3-6A and 8-9) sized to fit tightly around the wearer's neck and wrist, respectively, to form water-tight seals. The sealing sleeves 30, 40 are provided to be stretchable around the respective first openings 31, 41 so that the sealing sleeves 30, 40 can be pulled over the wearer's head and hands, respectively, when donning and doffing.

(14) FIG. 3 shows an embodiment in which a wrist sealing sleeve 40 is constructed from a flexible tube that includes a substantially waterproof textile composite 43 with a first opening 41 configured to fit tightly around the wearer's wrist and a second opening 42 which is configured to be joined by a seam around wrist opening 4 of a waterproof garment. The first opening 41 is configured to fit tightly around the wearer's wrist to provide a substantially water-tight seal between the skin and the textile composite 43. The textile composite 43 is stretchable at least around the circumference of the first opening 41 to allow the wrist sealing sleeve 40 to be stretched over the wearer's hand when donning and doffing the waterproof garment.

(15) In some embodiments, the textile composite 43 is stretchable to allow at least 100% elongation around the wrist opening 4 before tensile failure. In some embodiments, the textile composite 43 is stretchable to allow an elongation greater than 300% around the wrist opening 4 before tensile failure. In some embodiments, the textile composite 43 is also stretchable along the length of the wrist sealing sleeve 40, between the first opening 41 and second opening 42, to allow improved movement of the wearers body. In some embodiments, the stretchability of the textile composite 43 along the length of the wrist sealing sleeve 40 is limited to 200% before tensile failure to allow for easier donning and doffing of the wrist sealing sleeve 40. In some embodiments, the stretchability of the textile composite 43 along the length of the wrist sealing sleeve 40 is limited to less than 100% before tensile failure to allow for easier donning and doffing of the wrist sealing sleeve 40. The reduced stretchability along the length relative to the circumference of the openings 41, 42 allows the tight-fitting wrist sealing sleeve 40 to be more easily pulled over the wearer's hand without overstretching the wrist sealing sleeve 40.

(16) The respective circumferences of the second opening 42 and the wrist opening 4 of the waterproof garment are configured to allow the hand to pass through the wrist opening 4 when donning and doffing the waterproof garment. If the textile 1 of the waterproof garment has minimal stretch, then the circumference of the wrist opening 4 should be larger than the largest circumference of the wearer's hand.

(17) In some embodiments, the substantially waterproof textile composite 43 includes a stretchable woven, knitted, or non-woven textile with at least one waterproof coating layer 48 applied to one or both sides of the textile. The textile composite 43 provides significantly improved resistance to tearing compared to the rubber sealing sleeves commonly used in the art. In the embodiment shown in FIG. 3, for example, the textile composite 43 includes a stretchable textile 47 combined with a waterproof coating layer 48, whereby the waterproof coating layer 48 is positioned on the inside face of the textile composite 43 so that it directly contacts the wearer's body. In some embodiments, the waterproof coating layer 48 has an outer surface that is smooth to provide a good water-tight seal between the textile composite 43 and the skin.

(18) In some embodiments, the stretchable textile 47 is a stretchable knitted, woven, or non-woven textile that includes synthetic yarns (e.g., nylon, polyester, polypropylene, and/or stretchable elastane yarns) and/or natural yarns. In some embodiments, the stretchable textile 47 is configured to provide at least 100% elongation around the circumference of the first opening 41 of the wrist sealing sleeve 40 before tensile failure. In some embodiments, the stretchable textile 47 is configured to allow an elongation greater than 300% around the first opening 41 of the wrist sealing sleeve 40 before tensile failure. In some embodiments, the stretchable textile 47 is configured to provide stretchability along the length of the wrist sealing sleeve 40 between the first opening 41 and the second opening 42 to allow improved movement of the wearer's body. In some embodiments, stretchability of the stretchable textile 47 is configured to limit elongation along the length of the wrist sealing sleeve 40 to around 200% before tensile failure to allow for easier donning and doffing of the wrist sealing sleeve 40. In some embodiments, stretchability of the stretchable textile 47 is configured to limit elongation along the length of the wrist sealing sleeve 40 to less than 100% before tensile failure to allow for easier donning and doffing of the wrist sealing sleeve 40.

(19) In some embodiments, the substantially waterproof coating layer 48 is made of a substantially water impermeable polyurethane film lamination that provides adequate stretch modulus and recovery to fit tightly around the wearer's body to provide a water-tight seal. The polyurethane film can be made of materials such as polyether-polyurethane, polyester-polyurethane, polycarbonate-polyurethane, and composites thereof. In some embodiments, the coating layer 48 includes a polyurethane coating or composite coating and film lamination. In some embodiments, the polyurethane coating or film lamination is moisture vapor permeable to allow moisture built up within the waterproof garment from perspiration to escape through the textile composite 43. In some embodiments, the polyurethane film has a thickness of between 0.01 mm and 0.1 mm. In some embodiments, the polyurethane film has a thickness of between 0.1 mm and 0.5 mm, and includes a foamed polyurethane that allows greater elongation of the textile composite 43.

(20) In some embodiments, the waterproof coating layer 48 is selected from a polyurethane material that can bond to a hot-melt waterproof seam sealing tape or adhesive film commonly used in the art to form a water-tight seal between the second opening 42 of the wrist sealing sleeve 40 and the wrist opening 4 of the waterproof garment 1. The ability to bond with hot-melt seam sealing tapes allows for easy mass production of the waterproof garments using conventional sealing techniques known in the art. It also allows for ease of replacement or repair of damaged sealing sleeves by the application of hot-melt adhesive seam tape or patches.

(21) In the embodiment shown in FIG. 3, the tubular shape of the sealing sleeve 40 is formed by joining two panels of the waterproof textile composite 43 at seams 44, 45. The seams 44, 45 are constructed to be substantially water-tight. In some embodiments, the seams 44, 45 are constructed by sewing and seam taping using a substantially waterproof hot-melt seam sealing tape 46. In some embodiments, the seams 44, 45 are ultrasonically welded and then reinforced with the seam sealing tape 46 to produce flat seam thereby allowing improved sealing around the first opening 41 of the wrist sealing sleeve 40. The seam sealing tape 46 is applied to the substantially waterproof coating layer 48 of the textile composite 43 to provide a good waterproof seal. In the embodiment of FIG. 3, the seam sealing tape 46 is applied to both sides of the textile composite 43 to provide additional reinforcement to the seam. In other embodiments, the wrist sealing sleeve 40 is formed from at least one flat panel of the textile composite 43 that is joined by at least one seam thereby forming the tube. In other embodiments, the tubular shape of the wrist sealing sleeve 40 is formed by constructing the textile composite 43 into a tubular shape and coating or laminating the waterproof coating layer 48 onto the textile composite 43 thereby eliminating the need for additional seams to create the desired shape.

(22) In some embodiments, the wrist sealing sleeve 40 can be trimmed by the user around the circumference of the first opening 41 to thereby increase the circumference of the first opening 41 to allow for a looser fit around the body.

(23) Referring to FIG. 4, a water-tight wrist sealing sleeve 40 is provided featuring an elastomeric reinforcement material 51 that is combined with the textile composite 43 around the first opening 41 of the wrist sealing sleeve 40. In some embodiments, the elastomeric reinforcement material 51 is configured to have a similar or higher elastic modulus than the waterproof textile composite 43 to provide improved stretch recovery after repeated donning and doffing. In some embodiments, the elastomeric reinforcement material 51 is configured to have a higher stretch modulus than the textile composite 43 to provide a firmer fit around the body, thereby improving the water-tight seal. In some embodiments, the elastomeric reinforcement material 51 is configured in two or more bands to improve comfort to the wearer. The elastomeric reinforcement material 51 is applied to the waterproof coating layer 48 and/or textile layer 47 of the textile composite 43. In some embodiments, the reinforcement material 51 is applied to the textile side 47 of the textile composite 43 to prevent fraying of the textile composite 43 around the edge of the first opening of the seal. In some embodiments in which the sealing sleeve is configured to be trimmed by the user, the reinforcement material is also configured to reinforce the cut area to prevent tearing or fraying from the cut edge.

(24) In some embodiments, the elastomeric reinforcement material 51 includes a knitted or woven textile, polymeric film or coating or fabric and film composite applied the to the textile composite 43 by laminating, bonding, printing, stitching, gluing or other process. In some embodiments, the reinforcement is an elastomeric polyurethane film with a thickness between 40 m and 300 m comprising a hot-melt adhesive on one side that is used to bond the film to the textile composite 43.

(25) In some embodiments, a second elastomeric reinforcement material 52 is combined with the textile composite 43 around the second opening 42 of the sealing sleeve 40 where the seam is joined to garment textile 1. The second reinforcement material 52 is provided for embodiments where the waterproof textile composite 43 is stretchable along the length of the sealing sleeve between the first opening 41 and second opening 42. The second reinforcement material 52 is configured to have a higher elastic modulus and/or lower elongation than the waterproof textile composite 43 to reduce the stretch in the area where the stretchable sealing sleeve 40 is joined to the waterproof garment textile 1 thereby providing a gradual reduction in stretch between the sealing sleeve and the non-stretch textile reducing stress at the seam and increasing the durability of the sealing sleeve attachment.

(26) FIG. 7 shows a cross-section detail view of the seam joining garment textile 1 at opening 4 to seal waterproof textile composite 43 at the second opening 42. The waterproof textile composite 43 features the second elastomeric reinforcement material 52 applied to textile layer 47. The waterproof textile composite 43 is joined to garment textile 1 by stitching 60, and the seam is made waterproof by the application of a substantially waterproof seam sealing tape 61 that bonds to garment textile 1 and the waterproof coating layer 48 of the waterproof textile composite 43. The second elastomeric reinforcement material 52 reduces the stretch of the textile composite 43 at the join to textile 1 thereby reducing the stress of the textile composite 43 at the join when the sealing sleeve is stretched.

(27) The second elastomeric reinforcement material 52 includes a knitted or woven textile, polymeric film or coating or fabric and film composite applied the to the textile composite 43 by laminating, bonding, printing, stitching, gluing or other process. In some embodiments, the reinforcement is an elastomeric polyurethane film with a thickness between 40 m and 300 m comprising a hot-melt adhesive on one side that is used to bond the film to the textile composite 43.

(28) Referring to FIGS. 4 and 6, sealing sleeve 40 with first opening 41 and second opening 42 is constructed from waterproof textile composite 43 that includes inner waterproof coating layer 48 and outer textile layer 47. The textile composite 43 is joined at seams 45 and sealed with seam sealing tape 46. Elastomeric reinforcement material 51 is provided around first opening 41, a second elastomeric reinforcement material 52 is provided around second opening 42.

(29) Another embodiment is shown in FIG. 6A whereby elastomeric reinforcement material 51 is provided around first opening 41 on the inside of the sealing sleeve 40. The elastomeric reinforcement material is positioned on the inside of the sealing sleeve to provide a tighter fit against the skin. Additional reinforcement material 51 can be provided on the outside of the sealing sleeve around the first opening 41 to provide increased modulus to provide an even further fit and/or to prevent fraying of the stretchable textile 47. The reinforcement material 51 on the outside of the sealing sleeve can also be disposed on the sealing sleeve in rings parallel to the first opening 41 that can be used as a guide for the user to trim the sealing sleeve to a required size.

(30) In the embodiment of FIG. 9, an additional elastomeric reinforcement material 53 is applied to the sealing sleeve 40 in the form of stripes along the length of the sealing sleeve 40 that reduces stretch along the length of the sealing sleeve 40 whilst maintaining adequate elongation around the opening circumference of the seam to allow for easier donning and doffing of the sealing sleeve 40. In some embodiments, the stripes of the additional elastomeric reinforcement material 53 can form a predetermined regular or irregular pattern.

(31) FIG. 8 shows another embodiment whereby a water-tight neck sealing sleeve 30 is provided constructed from a flexible tube that includes a substantially waterproof textile composite 43 with a first opening 31 configured to fit tightly around the wearer's neck and a second opening 32 which is configured to be joined by a seam around neck opening 3 of a waterproof garment. The first opening 31 is configured to fit tightly around the wearer's neck to provide a substantially water-tight seal between the skin and textile composite 43, the textile composite 43 is stretchable at least around the circumference of the first opening to allow the sealing sleeve to be stretched over the wearer's head when donning and doffing the waterproof garment. The neck sealing sleeve 30 and any ankle sealing sleeves can be configured in a same or similar manner to the wrist sealing sleeves 40, but can be sized differently so as to form water-tight seals at the neck and ankles, respectively.
