The site is now protected under the Sonoma County Agricultural Preservation and Open Space District, and volunteers tend the site throughout the year by clearing brush and weeds and otherwise maintaining habitat for the plant. The company has been consistently innovating, tailoring, and perfecting the creation of premier hemp products from the bast and hurd (wood) and expanding the use-cases for the full hemp plant - sustainable use cases that benefit producers and manufacturers in construction, as well as textile (woven, and non-woven) industries. Hemp and flax are the most well-known bast fibers, followed perhaps by ramie, a nettle-like plant native to eastern Asia used for coarse fabrics and rope. Hemp fibers can be between approximately 0.91 m (3 ft) and 4.6 m (15 ft) long, running the length of the plant. About Us People behind Bast & Faser „Bast und Faser GmbH“ aspires the research and development of machines to extract fiber material from renewable resources. Hemp Hurd Fiber. BastCore’s connection to our broader fiber system will create opportunity for larger retailers looking to make inventive blends of hemp and Climate Beneficial Wool. The traditional procedure for the production of fibers from hemp is field retting, a natural process which results in fibers of variable quality due to differences in weather conditions. Natural Bast Fibers are strong, cellulosic fibers obtained from the phloem or outer bark of jute, kenaf, flax and hemp plants. In drafting, the fibres become straightened by passing the sliver through a series of rollers with increasing rotational speed in the forward direction. Micronized core wood. They are classified in the genus Asclepias, which sits in the same family as dogbane. While the long bast fibers have been used to make paper almost for 2 millennia, the woody core fibers have rarely been so used. seed leaves). They are a family of fibers that allow for the entire plant to be used. Improved microorganisms or enzymes could augment or replace traditional water retting. Bast fibers give the plants strength. Seed sources and varieties. With permission and guidance from indigenous land tenders, we harvested dogbane for the Bast Fiber Exhibit from a patch in Sonoma County that has been continuously tended for thousands of years and is within the traditional and ancestral territory of Southern Pomo and Coast Miwok peoples. Hemp is already used as a raw material for papermaking and other industrial productions. Bast fibers are flexible and are soft fibers that run lengthwise along the stems with a woody cellulosic core in the middle. Bast fibers give the plant its strength and durability. Bast Fibers are annually renewable fiber crops with many environment-friendly features. Skip to … What are Bast Fibers? Bast fibers form the outer layer.

In addition to working with hemp and flax last year (read more in our 2019 blogs), we collaborated with local farmers and indigenous land tenders to harvest and process three native bast fiber plants—dogbane, nettle, and milkweed—into fiber suitable for spinning into yarn. The fibers we processed were finer than those of hemp and similar to those of flax. While the bast fibers were quite short—seldom reaching more than one inch long—they were extremely fine, similar to those of dogbane. Well-crafted hemp textiles are durable, breathability and have strong thermal qualities, as well as being mildew-resistant and hypoallergenic. 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. 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. (Photos by Paige Green, left and right, and Nicholas Wenner, center). In addition to fiber and food, nettle offers a green dye from the leaves and a yellow dye from the roots. It supports the conductive cells of the phloem and provides strength to the stem. They are annually renewable crops, growing in 90 to 100 days. 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. A Missed Opportunity to Learn from Failure, Tips For Looking After Organic Cotton Clothes. Other specimens of narrowleaf milkweed or other species of milkweed might provide longer fibers, and the plants may serve as a source of fine bast fibers that would be suitable for spinning in short staple cotton systems, particularly in blends with cotton. Many of the material handling issues that we have helped clients with have featured unique commodities. Increased delivering speed from the drafting rollers decreases the number of twists per length. The fibers carry nutrients and support plant structure while the plant is growing, but also are naturally absorbent yet strong when wet, a desired characteristic in many non-woven products. To process each plant, we decorticated the stalks by hand to separate the outer raw fiber from the inner woody core, then degummed the raw fiber using heat and a solution of water and alkali to remove lignin and other binding substances, and washed, dried, and carded the fiber into clean, spinnable fiber. 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. In a rare silver lining to recent fires in the region, the patch burned in 2017 as part of the Tubbs Fire, and those tending the patch now report vigorous and healthy growth, partly due to the reduction of invasive Himalayan blackberry and Harding grass. It is commonly called bast, which refers to the fibers which grow on the outside of the plant’s stalk. The pith is empty space in dry stems. Europeans gave the Latin name Apocynum cannabinum to the plant because of the similarity between its fiber and that of hemp (Cannabis sativa). 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]. When Some recent oilseed cultivars are grown Researchers have also found bast fibers—likely nettle—at sites in the Czech Republic from around 32,000 years ago. The twisting forces the fibers to take a helical structure and results in inherent sliding friction between the fibers and in axial strength in the yarn. It belongs to the eudicotyledons like hardwoods, numerous bushes, and herbs since it has two cotyledons (i.e. Cordage is an age old use for hemp fiber. Nettle (Urtica dioica) grows perennially in moist soils throughout North America. Hemp fiber is one of the dominant classes of bast natural fibers, commonly procured from the hemp plant with the species of Cannabis. Historically, so many different applications have been found for hemp’s stalk. At the industrial scale, the hackling is performed using metal-pinned brushes and rotating rollers to pull the fibres forward. Smaller, lower cost systems are also available. Hemp paper is useful for specialty applications such as currency and cigarette papers where strength is needed. Hemp Stalk Bast. Selecting monoecious strains overcomes the problem of differential maturation times and quality of male (staminate) and female (pistillate) plants (males mature 1–3 weeks earlier). Similar to flax, dogbane stalks have relatively few and relatively small leaf nodes, which supports the production of long, continuous fibers. Hemp bast fibers are a valuable source from which cellulose nanocrystals (CNCs) can be extracted. Publisher - a knowledge-base repository of textile articles. While milkweed floss is too smooth to spin easily and does not form strong yarns on its own, the fiber is hollow and has been used commercially as a fill and insulation material for decades. Hemp, cannabis plant cultivated for its useful bast fiber and nutritious edible seeds. „Bast und Faser GmbH“ aspires the research and development of machines to extract fiber material from renewable resources.

As crops, the plants can play a valuable role in crop rotations and provide high yields of both food and fiber with relatively minimal inputs. Members include farmers, processors, manufacturers, researchers, entrepreneurs and marketers We are working to fill the critical need for sustainable alternatives to man-made fibres. Bast fibers have been highly regarded for beautiful, durable textiles throughout history and into the modern era. Dogbane grows throughout much of North America. Alongside milkweed, it was the finest of the fibers we processed, and dogbane fibers were similar in length to those of nettle. The ring distributes the yarn onto a rotating bobbin. Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the "inner bark", sometimes called "skin") or bast surrounding the stem of certain dicotyledonous plants. We have helped clients find solutions to convey a variety challenging products . 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] . Dogbane fiber shows a good combination of fineness and length. Later the fibers may be cut to shorter lengths. The 60,000-square-foot BastCore plant at 715 Shady St. takes in hemp stalks from a nearby farm to process into fiber, chips and other materials for use across different industries. earlier than the females, to produce superior fiber. Fire was used historically as a tending strategy by indigenous people to clear brush and promote the growth of dogbane, but recent fire regulations and nearby developments have made it difficult to maintain this practice. Another strategy has been to select stems that are hollow at the internodes, with limited wood, since this maximizes production of fiber in relation to supporting woody tissues. 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). Along with bamboo, hemp is one of the fastest growing plants on Earth. Hemp fibers can be between approximately 3 – 15 feet long, running the length of the plant. Well drained, nitrogen rich and non-acidic soil are essential for hemp … As a vigorous, perennial source of fine fiber and habitat, dogbane has much promise as a component in regional fiber systems.

During this process fungi and yeasts colonize the hemp and produce polysaccharide-degrading enzymes, which macerate and disrupt We aim to develop the correct fiber for each customer and deliver it on a consistent and timely basis from reliable, secure sources, thus expanding the global bio fiber … In fact, many landscapers and home gardeners struggle with dogbane taking over the areas they tend, and in some agricultural contexts the plant is considered a weed and competes well enough to create significant yield losses in fields of soy, corn, and other crops. How can I not be aware of how out of balance the systems that sustain us are? The stalk of the plant may produce around 1500 – 2000 lbs of textile-grade fiber per acre, compared to about 600-1200 lbs per acre for cotton, the flowering head can be used to produce CBD, and the remaining woody core can be turned into products such as building materials and bio-fuels. 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). Bast refers to the phloem, or tissue that grows along the stems or trunks of plants. At industrial scale, the stretching part of this process is called drafting. The extracted fibres are in the form of large fibre bundles useful in non-woven fibre mats, which are made by air-drying and needle punching with uncontrolled and thereby random fiber orientation. Mcore. Georgia-Pacific, a privately held subsidiary of Koch Industries, produced such brands as Brawny paper towels and Quilted Northern toilet paper. We use 100% whole hemp stalks, which is commonly called bast. Bast refers to the phloem, or tissue that grows along the stems or trunks of plants. Hemp has been widely cultivated as a source of bast fibers. gracilis), hoary nettle can grow very tall, commonly reaching above 8 feet. Bast fibers can be obtained either from cultivated herbs, such as flax, hemp, and ramie, or wild plants, such as linden, wisteria, and mulberry. Hemp is an annual plant and can grow on a wide spectrum of soils. The middle row is ½” bast fiber and ¼” bast fiber. Composite grade bast fiber. The primary hemp fiber is attached to the core fiber by Pectin – a glue-like soluble gelatinous carbohydrate. All three plants have value as perennial crops that grow well in local climates. In addition to working with hemp and flax last year (read more in our 2019 blogs), we collaborated with local farmers and indigenous land tenders to harvest and process three native bast fiber plants—dogbane, nettle, and milkweed—into fiber suitable for spinning into yarn. These fibers require relatively little processing compared to hemp, and fibers fine enough for many purposes can be obtained directly from dried stalks without retting or degumming. The floss was used at an industrial scale during World War II as a fill for life jackets and it is currently processed and used on a small scale for winter jacket insulation. The Hemp Fiber Classifier has revolutionized hemp fiber processing. We paired specimens of each plant with samples of raw fiber, degummed fiber, hurd, seeds, and other products, such as edible leaves from nettle and flower buds from hemp. The bast fibers can be used to make textiles that are 100% hemp, but they are commonly blended with other fibers, such as flax, cotton or silk, as well as virgin and recycled polyester, to make woven fabrics for apparel and furnishings. The preserve hosts a day of cordage making and stewardship each winter, and you can read about a recent event here.

Typical architecture of categories of cultivated Cannabis sativa. Hemp belongs to the Angiosperm phylum since it has vessel elements in the woody core (xylem) like hardwood. It was also one of the first plants to be spun into usable fiber 50,000 years ago. Two kinds of fibers are derived from the hemp plant’s stalk. In lab-scale, the fibres are isolated with hand The windrows are baled at 12% moisture content and the bales are transported for processing to remove and separate the bast and hurd fibers. The degree of branching and height are determined both by the density of the plants and their genetic background. All Rights Reserved. Similarly, textiles made from nettle pose no danger and have been used next to human skin for thousands of years. The inner two fibers of the plant are woodier and typically have industrial applications, such as mulch, animal bedding, and litter. Textile School incorporates knowledge associated to textiles right from fibers to its end usage including textile processes, trade-offs, know-how and textile standards.
