The effect of physical factors on the process of physical-mechanical degumming of flax fibers

Abstract: This paper presents results of studies on a new physical-mechanical method of degumming of flax fibers in order to determine optimal parameters of the process for obtaining high-quality fiber.The study was carried out on an experimental device where lengthwise and crosswise flow of the liquid through a straw batch was applied and where the following process parameters were controlled: temperature, flow velocity, and time of the process. The pH was maintained at a stable neutral level. The degumming process was… Show more

“…n Hemicellulose content in % was determined according to the Polish Standard BN-77/7529-02. The percentage of hemicellulose content was determine by dissolving hemicellulose contained in fiber with 1% sodium hydroxide, draining, drying and calculation of hemicellulose content based on weight loss [26].…”

“…It is known that each extraction process, such as decortication, water retting, dew retting as well as enzymatic, chemical, physical or any other treatment of fibre affects, to varying degrees, the degumming of fibre from the woody part, which is caused by the reduction in pectins, lignin, hemicellulose, waxes and fats in the fibre itself, leading to the removal of impurities and the division of fibre slivers into smaller thinner complexes. Therefore fibre parameters such as: length, linear mass, tenacity, homogeneity and efficiency depend on the extraction technique [12]. The results of chemical analyses of the fibre composition after each stage of the processing are presented in Figures 8-12.…”
