OPTIMIZATION OF THE DELIGNIIFICATION PHASE OF HEMP FIBER
Herald of Technological University, 2023Cellulose 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

Thermal Stability of the Hemp Fibers and Fabrics
Advanced Materials Research, 2012With 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; A Minor American Fiber Crop
Economic Geography, 1946ture 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 ...
