Hemp fibers can be approximately 3 to 15 feet (1 to 5 meters) in length. ... which are the fibers that grow on the outside of the plant’s stalk. As a by-product, hemp straw and its fibers are mainly used for the production of paper or geo-textiles, the reinforcement in composite materials as well as building material. Hemp is traditionally known as a fiber plant and most historical cultivation of the plant in the United States from the 17th to mid-20th centuries was with fiber use in mind. 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. Seed sources and varieties. Hemp fabric is a type of textile that is made using fibers from the stalks of the Cannabis sativa plant. Bast fibers are the fibrous part of the plant just below the bark. In our country we do not have large fields to enable retting processes. The fiber is the most valuable part of the hemp plant. At the moment we offer compressed hemp fiber packed in two ways: Small bales (11 kg) tied with a string. I am planning to use hemp bast fibers to reinforce bioplastics like PLA. 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. Hemp bast fiber must be separated from the woody core by mechanical means (decortication) or by the process of "retting" (rotting). Bast fiber is one of the strongest and most durable of all natural textile fibers, and will outlast others by many years. Fibers from hemp are blended with a range of products and solutions including concrete and fiberglass. Use Cases. Hemp is an annual plant which at maturity develops a rigid, woody stem ranging in height from 1.2 – 5 m, (3.9 – 16.4 ft), and having a diameter from 4 to 20 mm, (0.16 – 0.79 in), (Hayward, 1948; Berger, 1969). Being able to produce soft, cotton-like textiles of hemp and flax is therefore the greatest challenge of the “green textile” trend. Bast Fibre Technologies Inc.

Hemp fiber is one of the dominant classes of bast natural fibers, commonly procured from the hemp plant with the species of Cannabis. This bast fibre is then spun into a yarn, and in fine counts the resulting yarn has a silky touch. Only niche production exists in linen, flax and hemp fibers. Hemp bast fiber is a low-cost graphene-like nanomaterial. If you have a hemp shirt or a hemp product, the made fiber is the hemp fiber. Image: Wikimedia Commons Why Hemp? 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. Bast fibers give the plant its strength and durability. We use 100% whole hemp stalks, which is commonly called bast. Flax and hemp are the most commonly available bast fibers prepared for spinning. Decortication & Processing. Bast fibers are flexible and are soft fibers that run lengthwise along the stems with a woody cellulosic core in the middle. It is the first 100% mechanized process that can separate up to 60,000 lbs per hour (AKA 30 tons per hour) of hemp at a fraction of the cost of hemp decorticators. 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. 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 is strong, holds its shape, and stretches less than any other natural fiber. It is commonly called bast fiber, which refers to the fibers that grow on the outside of the plant’s stalk. Until now, many hemp processors have avoided the hemp fiber market due to the high cost of hemp decortication equipment. Our HempTrain™ advanced hemp processing technology, is capable of producing clean, long, structurally intact bast fiber. Ultrasonic Hemp Fiber Processing. The highest bast fiber content after decortication (BCD) was recorded in Ivory and the lowest in Fédora 17, … The primary hemp fibers can be used for composites, reinforcements, and … 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. The bast portion is typically 14%. This is hemp’s famous bast fiber. With the growing market for hemp seeds and phyto-cannabinoids comes an increasing production of hemp straw. Bast fibers were grown in Europe, North America and Asia in larger quantities until the nineteenth century. Bast fibers have been highly regarded for beautiful, durable textiles throughout history and into the modern era. These are long (bast) fibers and the short (core fibers). The long, strong […] Hemp is also one of the bast fibers known to ancient Asians, long before the birth of Christ. Natural retting is considered to be impractical for modern industrial purposes, but this low technology will always be appropriate somewhere, and never completely obsolete. Hemp decortication is the process of separating the hemp plant into bast fiber and hurd fiber. The primary hemp fiber is attached to the core fiber by Pectin – a glue-like soluble gelatinous carbohydrate. 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. Hemp Bast Fiber . Hemp fibers can be between approximately 3 – 15 feet long, running the length of the plant. Bast can be extracted from the inner barks of some trees, vines, and plants, such as hemp, nettle, and flax. The bottom row is hemp fiber fines resulting from the separation. Bast fiber is the plant fiber collected from the inner bark or “skin” that surrounds the stem of certain plants. We can load up to 300 kg on 1 euro pallet (0.8m x 1.2m x 2.4m tall). Hemp crops are high-yield crops that produce more fibers than cotton or flax, per acre. The fiber is around the outside of the plant and comprises one-third of the weight. They’re used for making hempcrete, clothing, textiles, bedding materials, absorbents, particle board, ceiling panels, compost, and other industrial products. Natural Bast Fibers are strong, cellulosic fibers obtained from the phloem or outer bark of jute, kenaf, flax and hemp plants. Dependent upon the processing used to remove the fiber from the stem, the hemp may be creamy white, brown, gray, black or green. U.S. domestically grown, processed, and manufactured: Hemp bast - nano fiber. Hemp Stalk Bast. Hemp bast ribbons before degumming and delignification. Smaller, lower cost systems are also available. 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. ... Hemp bast ribbons - decorticated Hemp fiber degummed and delignified Microcellulose fibers Hemp is a strong, durable, though harsh bast or phloem fiber, having a core which is characteristic of hardwood fiber. They are annually renewable crops, growing in 90 to 100 days. Bast fiber content (%), separated from the shives with the lab-scaled hemp stem decorticator, was significantly different between groups (p < 0.001). The fibers are traditionally separated from the other plant material through a process called retting. Many of the material handling issues that we have helped clients with have featured unique commodities. 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. Hemp, cannabis plant cultivated for its useful bast fiber and nutritious edible seeds. The common features of natural fibers along with inherent mechanical, thermal, and acoustic properties of hemp fibers make them beneficial for reinforcements in polymer composite materials [35,59,60] . 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. Hemp fiber has may applications, including industrial uses. Compressed Bast fibre bale .75m x .75m x 1.2m weight 230 kg Activated carbons, templated carbons, carbon nanofibers, carbon nanotubes, and graphene have all been intensively studied as materials for supercapacitor electrodes. Hemp production for fiber and/or grain can be highly mechanized with labor demands per acre similar to that of other agronomic crops, except for weed control and harvest operations which require relatively more time for hemp. Hemp fibers are used for textiles, paper, building materials, and other industrial products. Bast Fibre Tech produces 100% plant-based, intact natural fibres with the technical and performance requirements for a wide variety of nonwoven applications. Bast Fiber a multitude of uses.

Home / Bast Fibers / Hemp Fiber (raw) Hemp Fiber (raw) Fibers are raw (not combed), yellow to gray in color, and 30-150 centimeters long. Once a hemp crop has matured and been harvested, hemp primary fibers are separated from the hemp stalk through the "retting" process. 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. Raw Hemp Fiber is one of the most valuable parts of the hemp plant. When harvested correctly, the fiber is actually stronger than steel. 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. It is commonly called bast, which refers to the fibers that grow on the outside of the woody interior of the plant’s stalk, and under the outer most part (the bark).
