Vinalon is a synthetic fibre, produced from polyvinyl alcohol using anthracite and limestone as raw materials. Vinalon was first developed by the Korean scientist Dr. Lee Seung-ki at the Takatsuki chemical research institute in 1939. The fibre was largely ignored until Dr. Lee Seung-ki defected to North Korea in 1950. Trial production began in 1954. North Korea, officially the Democratic Peoples Republic of Korea (DPRK; Korean: Chosŏn Minjujuŭi Inmin Konghwaguk; Hangul: 조선민주주의인민공화국; Hanja: 朝鮮民主主義人民共和國), is a country in eastern Asia, covering the northern half of the peninsula of Korea. ... ...

Under the slogan of resolving the clothing problem through vinalon, North Korea constructed a vinalon plant in Hamhung, South Hamgyong Province, in 1961. Its original annual capacity of 20,000 tons has been expanded to 50,000 tons. Thanks to an all-out support from the government, it took only about a year to complete the construction of the plant, giving rise to the terminology of "vinalon speed," a new concept meaning the prompt completion of projects. 1961 (MCMLXI) was a common year starting on Sunday (link will take you to calendar). ...

The factory complex also produces other chemicals. Some defectors from North Korea have claimed that Dr. Lee Seung-ki was involved in chemical weapons research and that the complex was used to produce them. Early detection of chemical agents Sociopolitical climate of chemical warfare While the study of chemicals and their military uses was widespread in China, the use of toxic materials has historically been viewed with mixed emotions and some disdain in the West (especially when the enemy were doing it). ...

Vinalon, also known as Juche fibre, has become the national fibre of North Korea and is used for the majority of textiles, outstripping fibre such as cotton or Nylon, which are only produced in small amounts in North Korea. Other than clothing, Vinalon is also used for military uniforms, canvas shoes, ropes and quilt wadding. However, Vinalon is most widely used for turning out military uniforms, quilt wadding and ropes. For use in ordinary clothes, vinalon is blended with cotton, nylon or wool. Needless to say, vinalon wadding is heavier than natural cotton. The Juche Idea (pronounced // in Korean, approximately joo-cheh) is the basic governing idea of North Korea, and colloquially the political system based on that principle. ... Cotton From Wikipedia, the free encyclopedia. ... Nylon represents a family of synthetic polymers, a thermoplastic material, invented in 1935 by Wallace Carothers at DuPont. ...

Vinalon is resistant to heat and chemicals but has numerous disadvantages: it is stiff, uncomfortable, shiny, prone to shrinking and difficult to dye. It is not produced outside of North Korea.

Riding the current flow of inter-Korean economic cooperation, vinalon is being considered in the South as a possible "pollution-free future-oriented new material."
