Rubber Peyton Scow

History 1820- Threads and fabrics 1839-Vulcanizing rubber was developed by Charles Goodyear 1876- British smuggled out rubber-tree seeds from Amazonia Bred to be resistant and sent to Asia plantations in Malaysia, Ceylon and Singapore. 1920s- Henry Ford planted 70 million rubber tree seedlings 1940s- Synthetic

What is it? Latex Synthetic Brazilian rubber-tree (Hevea Brasiliensis) Dandilions 200 plants Synthetic Emulsion styrene-butadiene rubber (E-SBR) Neoprene

neoprene Polychloroprene Acetylene and hydrochloric acid Protective glove, apparel, wetsuits, technical hoses and belts, seals and membranes, and coating for wires. Resists acid, alkali, alcohol, oil and solvents

Elastomers Natural or synthetic Stretch repeatedly at least twice length Immediately return back to normal length Rubber is the oldest

How is it made? V cut in tree Filtered Washed Reacted with acid to make the particles coagulate Pressed into sheets Dried Mastication- machines break up raw rubber using mechanical rollers and presses to make it softer, easier to work, and more sticky. Chemicals added Calendering- Shaped by roller Extrusion- Squeezed through holes to make hollow tubes Vulcanized- sulfur is added and heated to 280°F

How is it made? Coated Dried Rolled Weaved Treated Expands 2 or 3 times Take out guild threads by carbonizing Cut https://www.youtube.com/watch?v=6TIXDbxtzMY

Build Round or rectangular cross section Excellent elongation Excellent recovery Low strength Low dye acceptance Sensitive to aging sunlight, body oil, perspiration, heat, chlorine bleach, and solvents Resists alkalis

Characteristics Non air-wicking Strength Flexibility Low noise and vibration Heat and pressure resistance Impermeable Flame resistant

Challenges Grommets are used to vent unbreathable membranes Hard to create buttonholes Zipper, Velcro, and snap closures Pinholes and tailor tacks will create permanent holes. Cannot be pressed Facings and hems must be under-stitched, glued, or heat welded
