The second section is probably one that only a space enthusiast would instantly recognise, the being a Beta cloth patch. Beta cloth was developed as a result of the Apollo 1 tragedy that claimed the lives of three astronauts in a fire, that happened whilst the spacecraft was on the launchpad. The investigation that was carried out after the fire concluded that the spacecraft interiors, and all of the items that were worn by the astronauts were in need of fireproofing. The resultant material to come from this for clothing and spacesuits was Beta cloth. It was created by NASA personnel in collaboration with two industry companies, Owens-Corning & DuPont. Beta cloth consists of fine woven silica fibre, similar to fiberglass. The resulting fabric does not burn, and melts only at temperatures exceeding 650 °C (1,200 °F). To reduce its tendency to crease or tear when manipulated, and to increase durability, the fibres are coated with Teflon. This was then used extensively in the construction of the Apollo program spacesuits, garments the were worn in the spacecraft, bags, pouches and insignia and emblems. When you see an image of an Apollo astronaut on the way to or from, or on the moon every name tag and mission patch will have been a made from Beta cloth. As mentioned above there was also a commercial and souvenir aspect to the production of these type of patch. Some were printed for the astronauts to fly on the mission and given to key space program employees, family and friends. Others were printed for sheer commercial gain; these are the type that are reasonably readily available on the market. They were printed on rolls of Beta cloth and cut into approximately 9”- 225mm squares. Some had lines, solid or dotted, printed in a grid to guide the cutting process, which can be seen at the edge.
