Vinalon
Vinylon, also known as Vinalon, is a synthetic fiber produced from polyvinyl alcohol, using anthracite and limestone as raw materials. Vinylon was first developed in Japan in 1939 by Ri Sung-gi, Ichiro Sakurada, and H. Kawakami. Trial production began in 1954 and in 1961 the massive February 8 Vinylon Complex was built in Hamhung, North Korea. Vinylon's widespread usage in North Korea is often pointed to as an example of the implementation of the ''Juche'' philosophy, and it is known as the ''Juche'' fiber. Vinylon is the national fiber of North Korea and is used for the majority of textiles, outstripping fiber such as cotton or nylon, which is produced only in small amounts in North Korea. Other than clothing, vinylon is also used for shoes, ropes, and quilt wadding. Japanese-Canadian textile artist Toshiko MacAdam used vinylon in her early works, as it was more economical than nylon. Vinylon is resistant to heat and chemicals but has several disadvantages: being stiff, having a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Communist Countries
A communist state, also known as a Marxist–Leninist state, is a one-party state that is administered and governed by a communist party guided by Marxism–Leninism. Marxism–Leninism was the state ideology of the Soviet Union, the Comintern after Bolshevisation and the communist states within the Comecon, the Eastern Bloc and the Warsaw Pact.

Communist states are typically authoritarian and are typically administered through democratic centralism by a single centralised communist party apparatus. These parties are usually M ...

Liberation Of Korea
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent.
