“…Chelator level alone did not affect strength. Fibers from this study were blended with cotton (50 : 50), spun as yarn in a miniature spinning system, and the yarn properties determined [ 118 ]. Results indicated that enzyme treatments affected yarn properties, with the highest enzyme level producing finer fibers, easier yarn construction, and better quality yarns.…”

The components of flax (Linum usitatissimum) stems are described and illustrated, with reference to the anatomy and chemical makeup and to applications in processing and products. Bast fiber, which is a major economic product of flax along with linseed and linseed oil, is described with particular reference to its application in textiles, composites, and specialty papers. A short history of retting methods, which is the separation of bast fiber from nonfiber components, is presented with emphasis on water retting, field retting (dew retting), and experimental methods. Past research on enzyme retting, particularly by the use of pectinases as a potential replacement for the current commercial practice of field retting, is reviewed. The importance and mechanism of Ca2+ chelators with pectinases in retting are described. Protocols are provided for retting of both fiber-type and linseed-type flax stems with different types of pectinases. Current and future applications are listed for use of a wide array of enzymes to improve processed fibers and blended yarns. Finally, potential lipid and aromatic coproducts derived from the dust and shive waste streams of fiber processing are indicated.

IntroductionIn the textile industry, flax fibrous materials are processed in the form of complex fibers fragmented through-thickness, since elementary flax fiber has a smooth spindle-shaped surface and, unlike wool or cotton, has no adhesion ability. The processes of preparation of flax fiber at the stage of spinning are aimed at ensuring uniform crushing of bast bundles into groups of fibers having optimal thickness and length. It represents a difficult technological task that can be solved through multi-stage and long-term actions. For this purpose, mechanical methods of splitting and stretching of fibrous semi-finished products (combing) are used in addition to partial chemical cleavage of cellulose companions, first during preparation of roving for spinning and then during woven fabrics bleaching and finishing cycles.One of the promising innovative directions in the production of fibrous materials is using enzymatic catalysis not only for selective action on certain types of polymer cellulose companions, but also for implementation of methods of textile semi-finished products nano-structural modification.The original approaches are based on the fact that actions of nano-sized catalytic protein molecules are spatially limited within certain structural areas of the fibrous matrix. This principle forms the basis for technologies of cotton bioscouring [1,2], with impact on the surface layer of the primary cell wall of the fiber, and wool processing [3,4] through selective splitting of proteins of epicuticle by special form of enzymes (keratinases) enriched in sulfur-containing amino acid (cysteine). Linen production has the widest opportunities for the implementation of biochemical methods of nanoengineering. It can be explained by the peculiarities in the morphology of flax fiber materials. Flax fiber is a multicomponent polymer system with multilayer organization and, due to this fact, is a perfect object for the implementation of techniques of spatially localized modification through rational biocatalysed splitting of binders in the structure of flax complexes.Major efforts have been carried out to improve and optimize of the enzymatic retting of flax which is a raw for textile industry. These efforts have been documented in numerous papers [5][6][7][8] and in the book The Biology and Processing of Flax [9]. Enzymatic scouring of linen fabric with use biopreparations for example Bioprep, Flaxzyme from Novozymes (North America) [10,11] and other analogs [12,13] is insufficiently described. New approaches to the development of a biochemical pretreatment process, leading to an improvement of the finishing technology through its unification, are formulated in Russia. for example Abstract:The bundles using layers that are generally referred to as «middle lamella» [16,17]. Moreover, in biology of plants, binding substances in plant tissues are traditionally divided into grades depending on massiveness of their deposits [17,18]. Figure 1a shows that middle lamella (1) is a thin layer cementing together adjacent plan...

“…However, flax fiber has some characteristics unfavorable to spinning, such as more nep and high rigidity, which could lead to the more hairiness, low strength, and bad evenness of flax ring-yarn [4,5]. The physical properties of flax fiber are given in Tab.…”

Limited studies exist related to the siro-spun spinning of flax ( Linum usitatissimum L.) and cotton (Gossypium hirsutum) blends. The purpose of this study was to determine the influence of various siro-spun processing parameters, including twist factor, space between two rovings and specification of traveler, on yarn qualities, such as yarn hairiness, tenacity and evenness. Results show that both specification of traveler and space between two rovings significantly influenced yarn hairiness and evenness, and heavier traveler and greater space led to decreased hairiness, but bad evenness. Twist factor influenced yarn evenness highly significantly, and smaller twist factor led to worse yarn evenness. Results also indicate the optimum levels of siro-spun process parameters as follows: twist factor αm = 150, space between two rovings 8 mm, traveler Fo 5/0. In relation to the general ring-spinning yarn, the siro-spun spinning yarns had decreased hairiness, little increased tenacity and similar evenness.
