Linen Most Useful: Perspectives on Structure, Chemistry, and Enzymes for Retting Flax
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 ret...
متن کاملRetting of Flax by Aspergillus niger.
In this study, retting was carried out by Aspergillus niger. The pH, galacturonic acid (GA), and total reducing sugar were determined; the end point was identified by the classic empirical processes and by the maximal GA content of the retting water. The process gave clear and resistent fibers, and the retting time was similar to that of current industrial processes with bacterial enzymes. Cont...
متن کاملBacteria responsible for the retting of Brazilian flax.
Twenty-two species of bacteria were isolated from Linum usitatissimum stored for retting. Achromobacter parvulus, Clostridium beijerinckii, C. saprogenes, C. saccharoacetoperbutylicum, C. perenne, and Pseudomonas aeruginosa and its achromogenic variety are retting agents. The last species mentioned performs the retting in only 72 hr. This is the first time A. parvulus has been shown to be a ret...
متن کاملOptimization 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...
متن کاملTitle : Producing Fiber Flax Using Modern Machinery and Field Retting
approv Steven J. Knapp Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in Oregon around 1957 before newly developed technology and fiber cultivars were available. The purpose of this research was to explore the use of modern methods and new cultivars. Field studies were conducted to evaluate cultivars and optimum cultural practices that would produce the highest yi...
