Abstract

A cuff, collar seal for a dry/waterproof diving suit consisting of a base layer of dipped natural rubber and an outer layer of dipped synthetic rubber. Preferably the synthetic rubber is polychloroprene and provides protection to the natural rubber layer against ultra violet, ozone and oils thereby extending the life of the seal. The seal takes the form of a tubular cuff or collar with a narrower opening to fit sealing around the body eg. neck, arm, leg and a wider opening at the opposite end that is fitted to the edge of the suit's body, sleeve or leg opening. The seal may be used on other garments such as survival suits, oil rig abandonment suits, chemical resistance suits and helicopter transport suits.

Description

DESCRIPTION
Dual Polymer Seals This invention relates to seals around garment openings. The invention is particularly but not exclusively concerned with rubber components used in waterproof garments such as dry suits, which are used in diving and other watersports.
By way of backgound, dry suits are conventionally made up from panels of strong woven fabric which has been rendered impermeable by treatment with nylon, neoprene, polyurethane or other suitable elastomer. The shaped impermeable fabric panels are joined edge-to-edge by stitching to make up the dry suit. The stitched seams are then sealed by laying hot-melt tapes along them and applying heat to melt the tape. The impermeable fabric stretches only slightly and is therefore incapable of forming seals around the wearer's ankles, hands and neck or waist. So soft rubber "seals" are provided on the suit at these positions.
The conventional "seal" takes the form or a tubular cuff or collar of natural rubber, with a narrower opening to fit sealingly around the body (neck, arm or leg) and a wider opening at the opposite end around which it is joined sealingly to the edge of the suit's body, sleeve or leg opening.
The natural rubber latex seals are exposed to sunlight and UV during use and this causes degradation and deterioration of the latex.
Our invention is to apply an additional layer of synthetic latex, such as polychloroprene to the base layer of natural rubber latex.
The base layer of natural rubber latex provides softness, flexibility and tear strength.
The upper layer of synthetic rubber latex protects the lower layer, and gives much greater resistance to UV, ozone and oils.
The conventional natural rubber latex seal has a normal life of one or two seasons. The addition of the synthetic layer to form the dual polymer seal will greatly extend the life of the seal.
The preferred embodiment of the invention will now be described with reference to the accompanying drawings: We use a chemical coagulant such as is already routinely used for forming natural rubber articles by dipping. Latices of the natural rubber and synthetic rubber are provided, each adapted (in a manner which may be well-known in itself to be coagulated by a certain type of coagulant, e.g. a heavy metal salt such as calcium nitrate. As conventional, the coagulant is applied to a former e.g. by dipping the former into a solution of coagulant. The coagulantcarrying former is dipped into the natural rubber latex where the coagulant"breaks through" (i.e. coagulates) the latex, according to wellunderstood practice, to form a rubber layer on the former. The former with the fresh rubber layer is then removed from the natural rubber latex and dipped into the synthetic rubber latex where residual coagulant which has permeated the rubber layer coagulates a thin layer of synthetic onto the rubber surface. The respective layer thicknesses are controllable by adjusting the dipping time.
Figure 1 is a side view of rubber cuff seal for a dry suit.
Figure 2 is an oblique view of the Fig 1 cuff seal.
With reference to Figures 1 and 2, a cuff seal is a natural rubber tube conventionally made by dipping a correspondingly-shaped former (not shown in drawings) into natural rubber latex. The seal has a small-diameter end which is to fit around the wearer's wrist, and a large-diameter end of the same size as the end of the suit sleeve to which it is to be fitted. These cuff seals are in themselves conventional. Similar seals may be required in other clothing such as survival suits, oil rig abandonment suits, helicopter transport suits and chemical resistance suits.
Accordingly to our new proposals a layer of synthetic rubber is applied to the surface of the natural rubber seal.
