Hemp as a source of textile fiber

Long fibers are very valuable in textile industry. Their differential processing will lead us to obtain threads and tissues with a wide range of qualities, from very resistant ones for rigging, sailing, sacks, nets, burlap, espadrilles,… even thinner threads and tissues with great resistance and breathability properties, which make them ideal either for working clothes, […]

Hemp as a source of textile fiber

Las fibras largas tienen un gran valor en la industria téxtil. El procesado diferencial de las mismas llevará a conseguir hilos o tejidos con un amplio rango de calidades, desde muy resistentes para cordajes, velas de navegación, sacos, mallas, estopa, alpargatas,…hasta hilos y telas más finos y con grandes propiedades de resistencia y transpirabilidad, que […]

Different types of fibers in hemp stem

Hemp stems have two types of fibers: Some long fibers that are rich in cellulose and pectin, present in the stem bark and other woody short fibers that are found in the stem core, which are richer in lignin and xylans, which are commonly known as hurds Short and long fibers from the hemp stem […]

Different types of fibers in hemp stem

El tallo del cáñamo posee dos tipos de fibras: Fibras largas ricas en celulosa y pectinas presentes en la corteza. Fibras leñosas cortas en el interior del tallo, más ricas en lignina y xilanos, y que comúnmente se denominan cañamiza. Fibras cortas y largas del tallo de cáñamo. Según la aplicación industrial, será más conveniente […]

Industrial applications of the hemp stem

The hemp stem contributes with applications for most of the industrial areas, with an added benefit that it is a sustainable raw material. Even in the technically demanding area of high technology, everyday there are innovative new applications for the micro or nano crystals of cellulose that could be extracted from hemp. The method for […]

Industrial applications of the hemp stem

El tallo del cáñamo brinda aplicaciones para prácticamente todos los sectores industriales, con el beneficio añadido de tratarse de una materia prima sostenible. Incluso en el exigente sector de la alta tecnología, cada día se hallan nuevas aplicaciones para los micro o nano cristales de celulosa que pueden extraerse del tallo del cáñamo. El método […]

Protein profile of hempseeds

Hempseeds have naturally a high content of proteins, which transform them into a very interesting vegetal protein source. But apart from it, their protein composition is very complete. Proteins are formed, at a molecular level, by different aminoacids, which are the basic units needed for their synthesis. In an analogical way, if proteins were a […]

Protein profile of hempseeds

La semilla de cáñamo per se posee un alto contenido en proteínas, lo que la convierte en una fuente de proteína vegetal muy interesante. Pero además, la composición proteica de las mismas es muy completa. Las proteínas están formadas a nivel molecular por diferentes aminoácidos, que son las unidades básicas necesarias para su síntesis. De […]

Lipid profile of hempseeds

The oil fraction of hempseeds is highlighted for its enormous proportion of non-saturated fatty acids (90%) and its high level of essential fatty acids, with a very optimum balance between them (figure 1) (Leonard et al. 2019; Farinon et al. 2020). The only fatty acids that are considered essential for human beings are the 𝛼-Linoleic […]

Lipid profile of hempseeds

La fracción oleosa de la semilla destaca por su enorme proporción de ácidos grasos insaturados (90%) y su alto contenido en ácidos grasos esenciales, con un balance muy óptimo entre ellos (figura 1) (Leonard et al. 2019; Farinon et al. 2020). Los únicos ácidos grasos que se consideran esenciales para los humanos son el Ácido […]
