Pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) in the presence of tetramethylammonium hydroxide (TMAH) was applied to kenaf (Hibiscus cannabinus) fibers in order to clarify the chemical composition of in situ lignin. The core and bast samples obtained from the middle position of variety Chinpi-3 were pyrolyzed at 500 °C for 4 s with TMAH. The core pyrogram revealed peaks retaining th...

This paper focuses on the effect of okra bast fillers biodegradation poly(vinyl alcohol) composites. Fibers were obtained from plant stems via biological degumming and subjected to different chemical treatments such as scouring, alkalizing, maleic anhydride treatment, vinyl acetate grafting. The fibers ground PVA-okra filler composites produced at 20 wt% fiber load solution casting method. test...

Bast fiber plants require a post-harvest process to yield useable natural cellulosic fibers, denoted as retting or degumming. It encompasses the degradation of cell wall’s non-cellulosic gummy substances (NCGs), facilitating fibers separations, setting fiber’s quality, and determining downstream usages. Due inconvenience traditional practices, bacterial inoculum enzyme applications for gained a...

This paper presents Bast, an object-oriented library of reliable distributed protocols. We show how Bast can be used to build fault-tolerant distributed applications , and how new protocols can be added to it. We discuss some distributed protocol design issues and the way these issues are circumvented in Bast. We brieey describe our Smalltalk and Java implementations of Bast, together with some...

Fiber extracted from castor plant is a bast fiber like hemp, jute, flax and kenaf. Based on the chemical constitutes; physical properties of these eco-friendly fibers agro waste are used in making different materials union fabrics reinforcement materials. In present study, was dyed with Eclipta prostrata extract evaluated for colorfastness color strength properties. The pre, simultaneous post-m...

This paper focuses on preparation of poly(vinyl alcohol) (PVA)-based composites reinforced with okra bast fibers at different percentages 5, 10, 20% via solution casting method. Fibers obtained from sections plants were biologically degummed and scoured Na2CO3. Selected bleached, treated maleic anhydride or grafted vinyl acetate. Mechanical, physical biodegradational properties the investigated...

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...
