Tercüme - Türkçe-İngilizce - gost

The subject of this passage, "iplik" can mean "thread", "yarn", or "filament", but since they seem to have used the French word for filament, written as "flaman" in Turkish, I assume that what they are talking about is a type of yarn or thread. The word "becomes" is not there, but it would logically follow the part that has been excerpted to complete the sentence (there is not verb, so the sentence is not complete).
