This article reviews the methods of degumming lignocellulosic plants. The following degumming methods are used: biological, chemical, mechanical and physical - retting in warm and cold water retting, dew retting, chemical treatment by acid and base, use of electromagnetic pulses and most promising - osmotic degumming with ultrasound. The paper presents the newest methods of degumming, especially the method of osmotic degumming combined with ultrasound. This new method, developed by Institute of Natural Fibres and Medicinal Plants, is a typical pro-ecological method, because degumming water after cleaning has to be recycled. The retting water has no odour and biochemical oxygen demand and chemical oxygen demand parameters are not high. For better cost-efficiency the osmotic degumming method can be applied also for degumming green decorticated fibres. © Taylor & Francis Group, LLC. Source

The chapter presents the inventory, achievements, and future prospects in the area of natural fibers production, processing and application, with special emphasis on the fibrous plants. Various parts of lignocellulosic plants like seeds, leaf, straw, bast, woody core have potential as the sources of valuable textile fibers, and are also suitable for use in automotive and aerospace industries, building materials, and biopolymers. Production of natural fibers does not damage the ecosystem. Plants, which are the source of natural fibers recycle the carbon dioxide. Fibrous plants remediate soil polluted by heavy metals. Nowadays the position of natural fibers in the world fiber market and the level of production is stable, thanks to the growing area of their application, not only in textiles (woven, knitting, non-woven, technical textiles), but in more eco-friendly composites, for production of agro-fine-chemicals, medicines and cosmetics as well as for nourishment. High biomass of some of fibrous plants can be used as a source of pulp and energy (solid fuel) and for the production of bio-ethanol and n-buthanol. Also GM modification brings new possibilities towards higher productivity, better quality and greater area of application of natural raw material. © 2010 American Chemical Society. Source

In this article the review of the methods of lignocellulosic plants degumming is presented. Generally, for the degumming, the following methods are used: biological, chemical, mechanical and physical - retting in warm and cold water retting, dew retting, chemical treatment by acid and base, use of electromagnetic pulses and most promising - osmotic degumming with ultrasound. The paper presents the newest methods of degumming, especially the method of osmotic degumming combined with ultrasound.

The fibrous plants can grow from Northern to Southern Arctic Circle. Different parts of these lignocellulosic plants are valuable sources of lignocellulosic fibres used in textiles and ecofriendly composites, sources of human food, nutrients, animal feed, agro-fine-chemicals for cosmetics and other area of application. That they are completely sustainable, renewable, and biodegradable and they recycle the carbon dioxide (CO2). Fibrous plants were well known to mankind more than 7 000 BC. Some of these bast fibrous plants like flax and hemp could be explored for reclaiming the soil polluted by heavy metals. The total production of all natural fibres is expected at the level 35-40 million tons/year. Special treatment and functionalization of these fibres provides new promising features and expected new properties of these fibres. Natural fibres can be processed for production of woven goods, knitting, nonwoven, technical and 3D textiles, also as the reinforcement of more friendly composites. These whole plants and woody parts (shives) and fibres can be used for production of special pulp and paper and seeds some for obtaining the agro-fine-chemicals. Natural fibres and derived products have very important properties like: excellent air permeability, high hygroscopicity, high heat absorption, no release of substances harmful for health, they not cause allergy effect, as well as safer behaviour in flame and fire combustion versus man-made fibres. The new emerging method of genetic modification (GM) of these fibrous plants provides promising performance e.g. higher level of cellulose, possibility of creating polyhydroxy-alcanate (PHA) natural polyester "in statu nascendi". Such GM modified plants are resistant to special herbicides, better resistant to drought also with controlled level of lignin and pectin. In 21st century the coexistence and competition between man-made and natural fibres is stabilized, especially in area of quality, sustainability and economy of their production. © (2013) Trans Tech Publications, Switzerland.

Flax is a very important fibrous bast plant, both for valuable textile fibres and composites applications and for bioactive compounds used in folk medicine, nutraceuticals and functional food. Flax seeds are rich in valuable fatty acids, amino-acids, phytoestrogens, cyclolinopeptides, lecithin, waxes, lignin, pectin, mucilage, etc. ω-3 and ω-6 polyunsaturated fatty acids (PUFA) are effective preventing cardiovascular and heart diseases. Flax-seeds lignans, class of phytoestrogens with beneficial impact in treating hormone dependent diseases, have been investigated for anticancer, antibacterial and antioxidant properties.Flax-seeds mucilage is recommended for treating gastrointestinal, throat and skin diseases due to its protective, laxative and emollient properties. © 2014 Copyright © Taylor & Francis Group, LLC.
