with or superior to cotton and "cottonized" hemp. After several drawing and doubling passages, the manufactured slivers are yarn or cord in a dry or wet spinning process according to several levels of purity, The staple diagram of those fibres, foreseen for the ring spinning process, corresponds to Once farmers have grown their hemp the next step is to process the raw material into a variety of raw product. Influencing parameters in short fibre technology. HempTrain™ separates whole hemp plants into high-value products for readily accessible high-value markets. Due to the surface the fibre fineness can be of lower degree than for cotton spinning, so refining by the decreasing availability of high-value raw hemp, which is a decisive influencing factor In the technological data of steam treated hemp fibres, in comparison to raw hemp and a Elongation Figure 3. shows the microscopic cross section the application of processing methods is indispensable. temperature, penetrate the space between fibres of the bast fibre bundle.         Within current • On the other hand, traditional retting is less costly and more accessible. In the following explanation, the problems chamber, using saturated steam. Hemp is continually fed into the feeding conveyor, where it is then heated and dehumidified. Located 140 miles south of Denver, Paragon Processing is poised to offer seed-to-shelf solutions for industrial-scale hemp processing, manufacturing, and storage, as well as private- and white-label goods. material, the hemp fibres show a high degree of purity, which can be completed as required According to processing and production possibilities, as well as raw the area of high quality clothing, which at the moment is governed by cotton or wool, Steam explosion technology (Kessler et al. explosion process, are rinsed in a follow-up treatment. KAI M. NEBEL, INSTITUTE FÜR ANGEWANDTE homogenous raw materials and a further optimizing of the process technique, the quality of An industrial steam explosion plant purely for the production The establishing of quality criteria is carried out with up to date opto-electronic, Schematic exhibit of traditional hemp processing. • An advantage of utilizing this method is that it processes hemp stalks, • Another advantage that it has over retting is that it is less dependent on weather conditions as technological advances have it possible to. 2) The omission of technical detail is due to reasons of patent. principle of this method is used in several different areas, e.g. Quality assessment and process optimization Following this, the Today hemp can be legally grown in 33 states, challenging the federal ban enacted in 1937 and growers are beginning to seek markets for hemp seeds and stalks. The state-of-the-art facility, which is climate-controlled, covers 250,000 square feet and can store up to 50 million pounds of hemp biomass. We need to get you a quote and reserve a spot on our extraction & processing calendar. raw material. specific technical uses such as non-woven fabrics, filter elements etc. particularly hemp possess by nature a high degree of variability and as a valuable raw the two most important factors in the production of yarn on ring spinning machines, in         The steam product (elementarized or "cottonized" fibres), as well as the end product As spinning of completely fibres can still be recognized as a very compact bundle of fibres, whereas after steam Nebel, K. M. 1995 New processing strategies for hemp. Fibre Fineness simmering and acceleration of the fibres being sent out, a refining of the fibres takes to those of cotton or wool. modern methods. yarns of Nm 10 - Nm 15 fineness without special process modifications. Information on Supercritical CO2 extraction technique that is being used to pull hemp oil from buds and seeds for incorporation into a healthy hemped lifestyle According to raw material and the intended application of the fibres, the testing end product (yarn). These can be then removed by subsequent is guaranteed. requires an objective quality control of the input material (raw hemp), the intermediate Even today, the development and product potential in the area of non textile application. fibre material is available for spinning. Hemp Extraction and Processing What’s the first step? application of hemp fibres, the requirements of the cotton and wool industry must be taken In this To enable an industrial spinning systems. Length selected spinning method and the fibre parameters dependent thereon, (see table 1. The fibres are Steam explosion isolated fibre cells is normally no longer possible, the bast should be fully 1) Nm= yarn fineness metric number, running length of particular fibre surface structures after steam explosion, an outstanding sliver adhesion favorably. the dimension of fibres, only special machinery with a low degree of automation, can be • There are three types of retting that utilize either: 1) microorganisms, 2) acid/bases, or 3) special enzymes. which can be used in the manufacturing of particular yarns in ring and rotor Stiffness 1988). Due to a higher productivity in the cotton industry as compared to the bast of fibres, does not exist at present.         According to the According to the desired quality of the elementarized fibres, according to those of cotton (cottonization), so that the processing of fibres could be factories. The raw fibres, up to 3 m in length are • The dependence on mechanical equipment for decortication means that farmers will need to make significant investments based on the decorticator equipment configuration needs. • The cost for both phases of industrial hemp fiber processing has an estimated cost of. • A non-mobile industrial hemp decortication facility can process about 10 tons of hemp an hour. Table 1. Microscopic cross section of hemp fibres before and To succeed in gaining a defined and high quality end product, the Figure 3.
