“…Water retting may require large amount of clean water and therefore is expensive but results in high quality fibres (Mwaikambo, 2006). Water retting was the valuable method of choice for many years because of high-quality fiber (Akin et al, 2001;Xu, 2010). In the mid-1990s water retting was mostly closed in western countries because of the contamination and consumption of the freshwater (Akin et al, 2001).…”

Even small additions of hemp fibres to fabrics result in sig nificantly higher surface resistance and increased heat sorption. The two major retting methods (dew retting and water retting) are used to extract fibbers for industrial uses. Both methods produce fibres of different quality. The results of research, carried out at the Lithuanian Institute of Agriculture, Upytė Experimental Station in 2006-2007, showed that dew retted and water retted hemp fibres differed in appearance. Hemp variety as a factor showed higher impact on physical fibre parameters: fibre content in dew retted and water retted hemp straw, dew retted hemp straw output from hemp stalks, the strength of fibre obtained from dew retted and water retted hemp. Seed rate as a factor did not show any significant influence on physical fibre parameters, and only some trends of higher parameters at higher seed rates could be observed. Statistical evaluation indicated that the year as a factor affected the majority of physical parameters tested. Statistical data processing also showed that the fibre extraction method as a factor had a significant influence on the fibre content in hemp straw in 2006, on the straw output from hemp stalks in 2007, on the fibre content in hemp stalks and hemp fibre flexibility in both years of investigation, on the hemp fibre strength in 2006.

“…Fucose, glucose, xylose, galactose, mannose, rhamnose, arabinose, and galacturonic acid, as well as glucuronic acid used as standard for chromatography were provided by SigmaAldrich. Viscozyme® is commercially available (Novozymes) and described in enzymeretting formulation (Akin, 2001). This multi-enzyme complex contains a wide range of carbohydrases (cellulase and hemicellulase).…”

“…As a consequence, the availability of natural fibers with the required quality for textile and composite industries is an important issue to fulfill the demand. Chemical retting (dilute solution of NaOH, Amel et al 2013) and enzymatic retting (using pectinase, Akin et al 2001;Dodd and Akin 2005) have been reported to produce fibers at the lab scale. Ultrasonic processing eventually coupled to chemical methods also appears as a promising way (Renouard et al 2014).…”

The characterization of fibers extracted from leaflet, the empty fruit bunches, leaf sheath, and spath of palm tree was performed. The fibers were extracted using three different procedures through chemical and /or enzymatic methods. The raw fibers studied have xylose contents between 13-22% and glucose content between 30% and 45%. The microfibrillar angle (MFA) values are in the order: bunch > spath > leaf sheath >> leaflet. Spath and leaf sheath, which naturally occur in a woven form present poor mechanical strength but could be readily used to produce cheap composites. Leaflet fibers extracted from date palm tree exhibiting a low MFA (16°), a high cellulose content, and cellulose crystallinity present the highest ultimate tensile strengths (≈ 1250 N.mm -2 ).

“…Therefore, they have been receiving more attention for the past two decades as reinforcements for polymer matrix composites [1]. However, the natural fibers present the disadvantages of quality inconsistence due to local climate, growth conditions, and nature of retting process (dew retting, enzyme treatment, etc) [2,3]. In addition, in order to improve the adhesion between the nature fiber and matrix, various chemical pretreatments (alkali, acetic anhydride, silane, etc.)…”

An improved Single Fiber Tensile Test (SFTT) for the natural fibers was depicted. Natural fibers have irregular shape, and are not uniform along the fiber length and also from one fiber to another. Applying the conventional method, which determine the fiber cross‐section by measuring the fiber diameter using optical microscopy, will result in inaccurate properties of the natural fibers with large standard deviation (SD). In the proposed new SFTT method, an accurate cross‐section area could be obtained from the Scanning Electron Microscope observation of a flat and clear fractured end surface of carefully selected tensile‐tested fibers and calculated using imaging analysis. Applying this new approach, tensile strength of different types of flax fiber, including bast fiber, enzyme‐retted and water‐retted fiber provided SD of less than 11%, while those of these fibers determined by the conventional approach had SD of over 24%.
