A method and apparatus for separating kenaf into fiber and core uses a modified stick machine conventionally used in the cotton industry for removing trash from unginned cotton. Lengths of kenaf are delivered onto the periphery of a saw cylinder so the toothed wheels snag the fiber and draw the kenaf
May 10, 2021 Once the kenaf stalks are harvested and the outer fiber is separated it goes through a refinement or combing process making the fiber finer and finer. It is an economic advantage to use presently available commercial harvesting equipment, if possible rather than investing in the development and production of kenaf specific equipment.
Jul 07, 2011 Kenaf bast were hermetically digested into single fiber using a 5 sodium hydroxide solution for one hour at four different temperatures 80 C, 110 C, 130 C, and 160 C. The hermetical digestion process used in this study produced fibers with high cellulose content 84.292.3 due to the removal of lignin and hemicelluloses.
Nov 16, 2020 5. Textile industry applications Kenaf Fiber is the thinnest and longest are used in the textile industry. Kenaf spin yarns have metric count from 12,000 to 25,000.Fibres spun from kenaf are extremely long. It is fond useful applications in making knit and woven textiles. Kenaf fiber can be blended very well with cotton and other fiber.
Current methods of processing Kenaf, Crotalaria and other related herbaceous fiber producing plants employ the use of a hollow revolving screened cylinder inside an enclosure for separation. This method leaves an unacceptably high percentage sometimes as much as 20 of the short woody innercore fibers in the processed product.
kenaf fibers in nonwoven fabrics may enhance biodegradabilty besides imparting greater acoustical insulation and light weighting the car. The nonwovens with kenaf fibers are 20 lighter than those from glass fibers the fiber density of kenaf is 1.4 gcm3 vs. 2.55 gcm3 for glass. The market for moldable automotive nonwovens is large.

Oct 01, 2006 The physical and chemical characteristics of fibers after biological, chemical, and enzymatic retting were studied for kenaf cultivated in Jeju, Korea. Retting removes non-fibrous materials leaving separated fibers. Quantitative chemical analyses of kenaf fibers after retting were conducted using gas chromatographymass spectrometry GC MS.
Jul 12, 2018 Brief introduction of hemp decorticator. Our hemp cutter machine is to use to extract the fiber of hemp, jute, kenaf, ramie, etc. With two big wheels, the machine is easy to move. The cleaning rate can reach 96 without any damage to the fiber itself. Hemp decorticator is suitable for processing plant fibers of hemp, jute, kenaf and red ramie in agriculture.
The late Walt Kammann of Yuma, Arizona grew about 100 acres 40 ha of kenaf in 1978 and some of this fiber was used by International Paper IP in cooperation with what is now Andritz Sprout-Bauer, Inc. to conduct the first commercial machine trial with kenaf-based newsprint.
1. Develop natural fiber preparation process and lab- scale apparatus. Deliver a prototype apparatus applicable to kenaf, flax, hemp. Focus on advanced methods of fiber preparation. 2. Design a scalable natural fiber preform manufacture process and produce a lab-scale prototype apparatus. Capability to produce multi-fiber preforms.
Sep 12, 2014 Contd- Upon harvest, the whole kenaf plant is processed in a mechanical fiber separator, similar to a cotton gin. The separation of the two fibers allows for independent processing and provides raw materials for a growing number of products including paper, particle board, animal bedding and bioremediation aids. 7.
the composite as fiber in the matrix-fiber composite. Kenaf has a bast fiber which contains 75 cellulose and 15 lignin and offers the advantages of being biodegradable and environmentally safe. Malaysian kenaf is composed of two distinct fibers, bast and core, with a makeup of about 35 and 65, respectively. Each fiber has its own usage ...
The kenaf plant has two fiber types the outer bark or bast portion 40 of the plant and the inner woody core material 60 2. There are many advantages of using kenaf fiber. Because a technology of separating kenaf core and bark has been developed, there is a possibility of using the entire kenaf plant or its separated parts.
In this research, single fiber cell separation method was studied and optimized. More than 200 fiber cell dimensional sizes of kenaf and apocynum were analyzed. Furthermore, the diameter changes of kenaf fiber cell before and after different degumming treatments were also explored. Results showed that the average length and diameter of kenaf ...
The kenaf fiber and the cotton fiber in the 5050 ratio was blended and was carded in a miniature carding machine and kenaf cotton webs were formed at first stage. The kenaf cotton webs produced were again carded to form the carded sliver Figure 4. Open end spinning Figure 5 Miniature open end spinning machine. Figure 6 Kenaf cotton ...
Fiber Separation Currently, the fiber is mechanically separated into bast and core portions. The bast fiber is then condensed into high-density bales. The high-density is necessary to get the full weight in a truck and to ship kenaf economically. The core fiber is being used in a number of other products such as oil absorbents. Transportation
For kenaf to become a successful alternative crop in Misissippi, yield per acre must be increased and products made from kenaf must be marketable. Studies will be performed to develop methods for maximizing yields which include new and better varieties. harvesting methods will be improved and techniques for separation of kneaf bast and core fibers will be improved.
