چکیده

Water retting is a traditional retting method that enables the low-cost production of bast fibers. This study investigated the retting of flax straws by distilled water for three different durations at room temperature in laboratory condition. The retting quality was evaluated in terms of the weight loss and degumming rate together with the fiber properties, which included color, linear density, and tensile properties. The degumming rate was defined as the percentage change in pectin content of phloem regions from the raw flax to water-retted flax. It was found that the dissolution of pectin and other contaminating materials during the beginning retting stage must have played an important role in pectin (content) and weight loss besides pectin degradation, and water retting gradually improved both the apparel properties, such as whiteness and fineness, and the mechanical properties of the fibers. Given the results, a water retting duration of six days should be sufficient to provide sound retting efficiency and reasonable fiber properties.

Comparative Evaluation of Physical and Structural Properties of Water Retted and Non-retted Flax Fibers

Flax stems of Modran variety were subjected to water retting under laboratory conditions and its physical properties were compared with non-retted fibers. Physical properties including percentage of impurities, weighted average length, linear density, tenacity and elongation were analyzed and the results were compared. The analysis of retted and non-retted flax fibers showed that retting is the...

Influence of Pectinolytic Enzymes on Retting Effectiveness and Resultant Fiber Properties

Enzymes have the potential to provide an improved method to ret flax for textile fibers. Retting is the separation or loosening of fiber bundles from the cuticularized epidermis and the woody core cells. New commercial pectinase products were evaluated both with and without ethylenediaminetetraacetic acid (EDTA) for retting efficiency. The Fried Test identified the most efficient enzymes and be...

Optimization for enzyme-retting of flax with pectate lyase

Flax (Linum usitatissimum L.) is an important commercial crop that supplies both linseed and bast fibers for multiple applications. Retting, which is a microbial process, separates industrially useful bast fibers from non-fiber stem tissues. While several methods (i.e., waterand dew-retting) are used to ret flax, more recently enzymes have been evaluated to replace methods used currently. Alkal...

Pilot plant for processing flax fiber

A flax fiber pilot plant is needed to process small samples of flax straw into fibers to facilitate research on retting and fiber properties. Our objective was to develop and test a modular design for a flax processing pilot plant based on a commercial line that was capable of cleaning fiber and seed flax straw from unretted, dew-retted, and enzyme-retted samples. The USDA Flax Fiber Pilot Plan...
