Modification and Characterization of Hemp and Sisal Fibers

Journal of Natural Fibers, 2014
This work is to investigate the effectiveness of the surface treatment technique of fiber impregnation in polymer solution in improving compatibility of natural fibers with matrix. Hemp and sisal fibers were treated through polymer coating in comparison to acetylation, alkalization/acetylation, and silanization.

Antimicrobial TEMPO-oxidized hemp fibers with incorporated silver particles [PDF]

Journal of the Serbian Chemical Society, 2012
In this paper, the preparation of the antimicrobial silver loaded hemp fibers were carried out by selective TEMPO-mediated oxidation, i.e. oxidation with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1 ...

Effect of Nanometric Particles of Bentonite on the Mechanical Properties of a Thermoset Polymeric Matrix Reinforced with Hemp Fibers. [PDF]

Polymers (Basel), 2023
The influence of the addition of bentonite nanoparticles on the tensile and flexural strength of a thermosetting polymer matrix composite material reinforced with hemp fibers was de-terminated. All composites were manufactured with 5% of bentonite in the

HEMP FIBERS AGAIN IN SERBIA: OLD FIBERS – NEW APPLICATIONS [PDF]

, 2022
U ovom radu su sumirane istorijske činjenice o gajenju i upotrebi konoplje u Srbiji i svetu, sa posebnim osvrtom na istraživanja i nove primene sa renesansom konoplje krajem 20. veka. Konoplja (Canabis Sativa L) je jedna od najstarijih gajenih biljaka, i predstavlja obnovljiv i održiv izvor vlakana, uglavnom za tekstilnu industriju.

Hemp as a raw material for fiber and paper production [PDF]

Hemijska Industrija, 2004
The goal of this study was to prove the feasibility of fiber and paper production from hemp. Experimental tests of the properties of paper obtained from hemp woody core fibers were performed. Fibers from hemp woody core were isolated by a chemical-thermo-

Replacement of Polymer Fibers with Hemp Fibers in Concrete

IOP Conference Series: Materials Science and Engineering, 2020
Abstract In our experiment, we tried to replace polymer fibers with hemp fibers and verify whether the properties and advantages of polymer fibers in concrete will be retained even with this interchange. Polymer fibers are added to the mixer to produce fresh concrete or mortar, and we did the same in our case.

Structural and Mechanical Properties of Hemp Fibers: Effect of Progressive Removal of Hemicellulose and Lignin

Journal of Natural Fibers, 2022
Hemicellulose and lignin were progressively removed from hemp fiber by hydrolysis. SEM, FTIR, XRD analysis and tensile properties evaluation on technical fibers were carried out to understand the structural and mechanical properties of hemp fibers ...

Bridging Disciplines: Applications of Forensic Science and Industrial Hemp

Frontiers in Microbiology, 2022
Forensic laboratories are required to have analytical tools to confidently differentiate illegal substances such as marijuana from legal products (i.e., industrial hemp). The Achilles heel of industrial hemp is its association with marijuana.
