“…4, lower), which are related to the pectin molecules, since approximately 70% of carboxyl groups of galacturonic acid units in pectin are esterified with a methoxyl group [21]. Depending on the treatment time, the relative intensities of this peak increased from 0.34 to 0.53 (Table 4), which indicate that etching of the fiber surface by air-plasma can expose the pectin molecules (and probably the other polymer constituents, i.e.…”

Abstract:In this research, a diffuse coplanar surface barrier discharge (DCSBD) type plasma reactor was used for the surface modification of raw linen fabric. Changes in physical properties and chemical composition of the fiber surface as well as color of the fabric were measured as a function of time of the atmospheric air plasma treatment. Furthermore, ageing of the effects created on the fiber surface by plasma treatment was also characterized in a period of 0-14 days elapsed after the plasma treatment. Significant differences were found between the properties of the raw and plasma treated linen fabrics, including increase of wettability, wickability, surface energy and O/C ratio, and decrease of water contact angle and deterioration of the waxy outer layer of the fibers. Most of the parameters depended on the time of plasma treatment (0-180 s). O/C ratio increased steadily with the increase of duration of the plasma treatment, which was explained by destruction of the waxy surface layer, creation of polar groups and exposure of cellulosic components. Most of the properties tested were found to be stable during two weeks of storage after the plasma treatment, indicating that the surface 'topography' created by plasma remained almost unaltered and the recovery of the etched waxy coverage of the fiber did not occur.

“…Experimental work showed that polygalacturonase enzyme alone was sufficient to ret flax fibres, without any added benefit from cellulases, hemicellulases or other plant-cell-wall-degrading enzymes generally present in fungal supernatants (Akin et al, 2004a;Evans et al, 2002;Zhang et al, 2000;Akin et al, 2002b). If availability and cost were not issues, the use of pure pectinases for retting would maintain fibre strength.…”

The program COST Action 847 Textile Quality and Biotechnology (2000-2005) has given an excellent chance to review the possibilities of the research, aiming at development of the industrial application of enzymes for bast fibrous plant degumming and primary processing. The recent advancements in enzymatic processing of bast fibrous plants (flax, hemp, jute, ramie and alike plants) and related textiles are given. The performance of enzymes in degumming, modification of bast fibres, roving, yarn, related fabrics as well as enzymatic bonding of lignocellulosic composites is provided.
