Bast fibers have been highly regarded for beautiful, durable textiles throughout history and into the modern era. The highest bast fiber content after decortication (BCD) was recorded in Ivory and the lowest in Fédora 17, … We can load up to 300 kg on 1 euro pallet (0.8m x 1.2m x 2.4m tall). Hemp fibers can be between approximately 3 – 15 feet long, running the length of the plant. Hemp fibers are used for textiles, paper, building materials, and other industrial products. Bast fiber is one of the strongest and most durable of all natural textile fibers, and will outlast others by many years. The bast portion is typically 14%. At the moment we offer compressed hemp fiber packed in two ways: Small bales (11 kg) tied with a string. Hemp is also one of the bast fibers known to ancient Asians, long before the birth of Christ. Hemp bast fiber is a low-cost graphene-like nanomaterial. This plant has been recognized as a source of extraordinarily tensile and durable textile fibers for millennia, but the psychoactive qualities of Cannabis sativa have recently made it harder for farmers to produce this immensely beneficial crop. Bast fibers are the fibrous part of the plant just below the bark. Hemp, cannabis plant cultivated for its useful bast fiber and nutritious edible seeds. Hemp fiber is one of the most strong, valuable, and resourceful parts of the hemp plant, growing from 3 ft to as tall as 15 ft. Hemp fiber manufacturers take bast fibers from the hemp stalk for its longevity, strength, and permeable traits and then cut them into shorter pieces. Bast fibers give the plant its strength and durability. The natural processing of Litrax bamboo allows the fibre to remain strong to produce an extremely high quality product, and the process results in a very durable textile. Hemp is a strong, durable, though harsh bast or phloem fiber, having a core which is characteristic of hardwood fiber. Hemp Stalk Bast. Decortication, one of the many steps involved in processing hemp, is the separation of hemp’s outer layer (bast fiber) from the inner core (hurd).Conventional decortication often uses the same hammer mill or hammer mill-like mechanisms (rollers, scutchers, gins, etc) that have been used for over a hundred years; using a beating action to break down hurd and fiber. Hemp bast fiber must be separated from the woody core by mechanical means (decortication) or by the process of "retting" (rotting). Bast fibers are plant-based natural fibers, which are cellulosic fibers found in the phloem of the stalk of bast fiber crops like industrial hemp.. Hemp is annual crop with a growth cycle of as little as 90-100 days. Our HempTrain™ advanced hemp processing technology, is capable of producing clean, long, structurally intact bast fiber. The bottom row is hemp fiber fines resulting from the separation. The fiber can be called bast and it is gathered from the fibers that grow on the outside stalk of the plant. Once a hemp crop has matured and been harvested, hemp primary fibers are separated from the hemp stalk through the "retting" process. HempTrain™ efficiently separates bast fiber from hurd in a processing technique that does not damage the fiber strings (bundles), keeping the fiber long, structurally intact retaining high tensile strength. Natural Bast Fibers are strong, cellulosic fibers obtained from the phloem or outer bark of jute, kenaf, flax and hemp plants. Hemp fiber possesses properties similar to other bast fibers (flax, kenaf, jute and ramie) and excels in fiber length, strength, durability, absorbency, antimildew and antimicrobial properties.

Hurds, or shives, are short woody hemp fibers typically found inside the stalk. The primary hemp fiber is attached to the core fiber by Pectin – a glue-like soluble gelatinous carbohydrate. Bast fibers were grown in Europe, North America and Asia in larger quantities until the nineteenth century. Most bast fibers come from flax, industrial hemp, kenaf or jute. Two kinds of fibers are derived from the hemp plant’s stalk. The variety of cannabis cultivated for hemp fiber and hemp seeds has only small amounts of psychoactive THC relative to cannabis grown for the production of marijuana or hashish. These are long (bast) fibers and the short (core fibers). Use Cases. Bast fiber content (%), separated from the shives with the lab-scaled hemp stem decorticator, was significantly different between groups (p < 0.001). The fiber is around the outside of the plant and comprises one-third of the weight. If you have a hemp shirt or a hemp product, the made fiber is the hemp fiber. Dependent upon the processing used to remove the fiber from the stem, the hemp may be creamy white, brown, gray, black or green.
