Oil Flax for Long Fiber Production

Machinery and Equipment for Rural Area, 2021
The paper presents the results of studies on the possibility of producing long flax fiber in scutching-and-breaking machines from flax straw obtained from modern varieties of oil flax in the form of whole stems of autumn and spring harvesting. The inexpediency of obtaining scutched flax from this type of raw material has been determined.

On the Mechanical and Thermal Behavior of PLA, PBAT, and PHBV‐Based Ternary Blends and the Effect of Short Flax Fibers as Reinforcing Agents

Polymer Composites, EarlyView.
Preparation and testing of biodegradable polymer ternary blends and composites with short flax fibres. ABSTRACT Bioplastics offer environmental benefits but they are costly and exhibit lower mechanical and thermal performance compared to fossil‐based counterparts. Poly(butylene adipate‐co‐terephthalate) (PBAT) exhibits high ductility but relatively low
