Hemp Fibers for Wastewater Treatment

2020
Sorption by low-cost lignocellulosic materials is the method receiving the utmost attention in searching for the best green approach in water pollution remediation. Among all the forms under which lignocellulosic materials are available for wastewater treatment purposes, a special position is occupied by lignocellulosic fibers such as hemp fibers.

Impact of a microwave treatment of hemp fibers on the hemp / cement interaction

2020
As the need to reduce grey energies is growing, materials such as hempcrete are in development. The thermal and acoustic insulation it offers, combined with the very low carbon footprint of hemp make it a first choice material. However, the great amount of hemp in hempcrete, combined with de weakness of the interface fibers/cement binder leads to poor ...

Modeling the tensile strength of hemp fibers and short-hemp-fiber reinforced composites

2015
Ecological and economical considerations foster replacement of man-made fibers by natural renewable fibers in various industrial applications. Proper description of the scale effect of fiber strength is important for theoretical estimation of the load-carrying capacity of their products.

OPTIMIZATION OF THE DELIGNIIFICATION PHASE OF HEMP FIBER

Herald of Technological University, 2023
Cellulose is used in almost all industries. The replacement of cotton cellulose, which is an imported product, with a domestic product is one of the most important problems. The use of industrial hemp and flax should be recognized as a priority direction of research in the search for alternative sources of raw materials. Flax and hemp straw contains in

Effect of gibberellin on the fibers of hemp

Economic Botany, 1961
The effect of gibberellin on the hemp plant is described. Gibberellin-treated plants show greater number of fibers as compared to controls. The individual fibers are larger in diameter, more lignified and up to ten times as long as the fibers from the untreated plants.

Flax and Hemp fiber-reinforced particleboard

Industrial Crops and Products, 2015
Abstract The objective of this study was to reinforce particleboard products with natural bast fibers which have high tensile strength and stiffness-to-weight ratios. Three-layered particleboards were manufactured from Wood, Hurd and Shive particle furnish and reinforced in the upper and lower face layers with aligned Flax and Hemp fiber mats ...

Thermal Stability of the Hemp Fibers and Fabrics

Advanced Materials Research, 2012
With the thermal gravity analysis and relative breaking strength test, both crystallization variability and the important temperature is determined in heating process of hemp fibers. Meanwhile, the critical time and temperature is got which have a effect on relative breaking strength of hemp fibres and the hemp fabric appearance.

Hemp Fibers: Old Fibers - New Applications

2014
Hemp (Cannabis sativa) was most likely the first plant cultivated by mankind for its textile use. Currently, the interest in hemp is focused on its use as a raw material for the production of environmentally friendly clothes, technical textiles and composite materials.

Hemp; A Minor American Fiber Crop

Economic Geography, 1946
ture has been precarious. Especially is this true of hemp, weak competitor of flax and cotton, of which the long soft fibers have long been used for twine, carpet thread, carpet yarn, sail cloth, homespuns, yacht cordage, and oakum. In the subsistence agriculture of much of early America, hemp was extensively cultivated to satisfy need for fibers ...
