Regarding the question of obtaining natural textile fibers from pine needles
(2023-03-31) Herasymchuk, Oleksandr; Tkachuk, Oksana
The article considers the possibility of obtaining natural textile fibers from pine needles as an environmentally friendly plant raw material. The economic and environmental potential of pine needle processing technology for producing fibrous material is substantiated. The main stages of the technological process are identified, including raw material collection, separation of clean pine needles, extraction of natural textile fibers and further processing for finished products. A pneumatic-thermal method for separating clean pine needles is proposed, and a schematic diagram of the installation for its implementation is developed. Based on a multifactorial experiment, a technological regime for extracting textile fiber from pine needles using a sodium hydroxide solution is determined.
