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.
Abstract:
A method for fabricating wetsuit garment including wetsuits, boots and gloves for water sports uses, comprising preparation of at least a substantially elastic joining member made of hot melt adhesive, and joining at least two interconnected panels of rubber foam or sponge by the substantially elastic joining member to cover and seal the seam between the two interconnected panels for firmly bonding the two interconnected panels for making a strong, elastic and flexible wetsuit garment.

Abstract:
A flexible apparel with non-stitch seams and a fabrication method thereof is provided. The non-stitch seams between foamed rubber sheets are sealed by coating a liquid sealant solution containing a thermoplastic polyurethane and a plasticizer.
Abstract:
A zipperless neck entry wetsuit provided in this invention comprises a torso portion and limb portions which are connected to and in communication with the torso portion respectively. The torso portion comprises an outer collar and a neck portion. The outer collar surrounds a neck opening defined as the only entryway for a wearer when the outer collar is stretched to expand the neck opening. Also, the periphery of the neck opening is zipperless. The neck portion is arranged in the neck opening and attached to an inner surface of the torso portion for being worn on the wearer's neck and being folded to cover and seal the neck opening.
Abstract:
A method of fabricating wetsuits and boots or gloves, made from rubber sponge material especially used for water sports, adheres each piece of the composition of the wetsuit or boots/gloves to be free from the problems of leaking or breaking caused by sewing or stitching. The method makes the finished garment not only strong and flexible, but also watertight so that the garment wearer feels dry and comfortable. The new method comprises the step of making an adhesion to form a cover, with the width of 1-25 mm and thickness of 0.3-1 mm, on the glued seams of the garment outer and/or inner surface in order to make each piece of the garment adhered completely with no sewing or stitching. The new method includes the additional step of putting the adhered panels of the garment into an oven at a temperature of 80-130° C., and for a time of 5-60 minutes, to make the adhesion vulcanized and cross-linked. That step forms a soft and firm cover of the seams and makes the finished products equivalent in strength to sewing or stitching but avoids the defects of leaking, breaking or discomfort caused by needle holes, thread breaking or unraveling from sewing or stitching.
