About the origin of sleeping bags
Early humans used animal fur to make warm clothing and sleeping mats. People, including the Eskimos living near the Arctic, still use it today. In the early 19th century, mountaineers and mountaineers began to test different sleeping bag systems. , early sleeping bags were filled with camel hair with excellent thermal insulation properties. Later, hollow rubber air cushions were invented and used for expeditions to the Earth's poles in the 1820s. In 1861, Francis Fox Tuckett tested the first Alpine sleeping bag prototype. In the mid-1860s, the envelope-type sleeping blanket design began to be perfected, and the part close to the ground had a hollow rubber coating as a thermal insulation layer on the ground.
Down was widely used in mattress fillings in the early 19th century because of its good thermal insulation properties. In the Victorian era of England, women even filled the inner layers of their skirts with down to keep out the cold. However, the processing and use technology of down did not change in the 19th century. It only began to develop in the middle period. The first recorded down sleeping bag was used by the British ALFRED MUMMERY expedition team in 1892. It was developed from the sleeping bag prototype of the Alpine Mountaineering Club and manufactured by the British Furniture Company. However, this was not the real meaning of production. Commercial sleeping bags. In 1890, the ajungilak company began to commercially produce sleeping bags. During this period, sleeping bags were made of stuffing. Until the 1820s, sleeping bags were special products, but due to the growing demand market, more companies began to design and production of sleeping bags. Based on the rise of exploration activities and mountaineering, the design and production of sleeping bags began to be continuously developed and improved in the 1830s. At this time, the mummy-style sleeping bag that could tightly wrap the body was born. British mountaineers also succeeded with this sleeping bag After the industrial revolution, due to the development of manufacturing and chemical industries, synthetic fibers began to be mass-produced. Due to their excellent thermal insulation properties, synthetic fibers began to be widely used in the production of sleeping bags.
