Abstract:
A process for flexibly making a wetsuit or the like is disclosed by integrally forming a functional surface layer on a rubber foam substrate sheet, thereby rendering the function of the surface layer for the wetsuit or the like.
Abstract:
A water sports garment with stitchless seams and a fabrication method thereof is provided. The stitchless seams between waterproof sheets are joined and sealed by coating a liquid sealant solution.
Abstract:
A surface-treated water sports garment with the outer rubber glue layer and a surface treating method thereof is provided. The rubber glue layer can closely join a rubber sponge layer to provide water-repellence and wear-resistance to the surface-treated water sports garment.
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 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:
A pyrolysis process is incorporated with a pyrolysis furnace in the process. The pyrolysis furnace comprises an upper screw and a lower screw juxtaposed to the upper screw to smoothen the thermal cracking process, with each blade helically formed on the screw shaft being notched in the periphery of the screw blade to form a plurality of bifurcated fins on the blade, such that besides the conveying of feedstock in the screw as driven by the blade, the bifurcated fins may serve as agitating elements, thereby simultaneously conveying the feedstock and agitating the feedstock for increasing the production efficiency of the pyrolysis.
Abstract:
Disclosed herein is a novel method of preparing shoe sole. The method of preparing shoe sole includes irradiating an uncured rubber sheet by laser beam to pattern and vulcanize a portion of the uncured rubber, tailoring the partially patterned vulcanized rubber into a shoe shape, and afterward fully vulcanizing the partially patterned vulcanized rubber sheet to form a shoe sole. An additional step of assembling the upper panel of shoe sole on the partially vulcanized rubber sheet is also performed.
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. Appropriate cutting and sewing processes are employed to finish the formation of a wetsuit and the improved non-absorbent and quick drying wetsuit is lighter and dries quicker when the wearer leaves the water since less water is absorbed by the wetsuit fabric as compared to a conventional wetsuit.
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.
