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. As part of our ongoing Bast Fiber Research effort, Fibershed engaged mechanical engineer Nicholas Wenner to connect with bast fiber growers, researchers, processors, and artisans to better understand the state of soil-to-soil systems for these unique plants. Hurds, or shives, are short woody hemp fibers typically found inside the stalk. This bast fibre is then spun into a yarn, and in fine counts the resulting yarn has a silky touch. Hemp bast ribbons before degumming and delignification. The long, strong […] Compressed Bast fibre bale .75m x .75m x 1.2m weight 230 kg Being able to produce soft, cotton-like textiles of hemp and flax is therefore the greatest challenge of the “green textile” trend. Bast fiber is the plant fiber collected from the inner bark or “skin” that surrounds the stem of certain plants. 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. These are long (bast) fibers and the short (core fibers). The middle row is ½” bast fiber and ¼” bast fiber. This is hemp’s famous bast fiber. Natural retting is considered to be impractical for modern industrial purposes, but this low technology will always be appropriate somewhere, and never completely obsolete. Raw Hemp Fiber is one of the most valuable parts of the hemp plant. Hemp fibers are used for textiles, paper, building materials, and other industrial products. Dependent upon the processing used to remove the fiber from the stem, the hemp may be creamy white, brown, gray, black or green. Bast fibers were grown in Europe, North America and Asia in larger quantities until the nineteenth century. So I would like to know whether we can skip the retting process and go directly to the mechanical decortication process and if so whether it is possible to obtain quality hemp bast fibers by skipping the retting process. Bast fibers have been highly regarded for beautiful, durable textiles throughout history and into the modern era. Hemp Bast Fiber . 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. The Hemp Fiber Classifier has revolutionized hemp fiber processing. Bast Fibre Tech produces 100% plant-based, intact natural fibres with the technical and performance requirements for a wide variety of nonwoven applications. ... Hemp bast ribbons - decorticated Hemp fiber degummed and delignified Microcellulose fibers Bast fiber content (%), separated from the shives with the lab-scaled hemp stem decorticator, was significantly different between groups (p < 0.001). ... which are the fibers that grow on the outside of the plant’s stalk. Hemp bast fiber is a low-cost graphene-like nanomaterial. I am planning to use hemp bast fibers to reinforce bioplastics like PLA. It is commonly called bast fiber, which refers to the fibers that grow on the outside of the plant’s stalk. The fiber can be called bast and it is gathered from the fibers that grow on the outside stalk of the plant. The Bast (Fiber) When you slice a hemp stalk in half, you’ll see, nestled in a snug hollow tube, a long, string-like band running the length inside. Home / Bast Fibers / Hemp Fiber (raw) Hemp Fiber (raw) Fibers are raw (not combed), yellow to gray in color, and 30-150 centimeters long. Decortication & Processing. Processing Solutions. Hemp Stalk Bast. They’re used for making hempcrete, clothing, textiles, bedding materials, absorbents, particle board, ceiling panels, compost, and other industrial products. The primary hemp fibers can be used for composites, reinforcements, and … Hemp is strong, holds its shape, and stretches less than any other natural fiber. Bast fibers give the plant its strength and durability. Until now, many hemp processors have avoided the hemp fiber market due to the high cost of hemp decortication equipment. Hemp decortication is the process of separating the hemp plant into bast fiber and hurd fiber. 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. In our country we do not have large fields to enable retting processes. The fiber is around the outside of the plant and comprises one-third of the weight. The specifications of growing bast fibers are representative for agriculture of rough, climate-resistant plants … Bast can be extracted from the inner barks of some trees, vines, and plants, such as hemp, nettle, and flax. We are working to fill the critical need for sustainable alternatives to man-made fibres. Two kinds of fibers are derived from the hemp plant’s stalk. 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. We use 100% whole hemp stalks, which is commonly called bast. 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.
