Kenaf (Hibiscus Cannabinus L.) is an annual herbaceous bast fiber crop, also known as kenaf, hibiscus, and bell hemp. Kenaf fibers have the characteristics of strong tensile strength, corrosion resistance, moisture absorption, and fast water dispersion, so they are widely used in many fields. It can not only be used to weave sacks, sackcloth, carpets, ropes, etc., but also an important raw material for the papermaking industry. In addition, kenaf bones can be made into fiberboard, and kenaf leaves are good feed for livestock.
Uses of kenaf after drying
Dried kenaf fibers have better stability and processing performance, and their uses are more extensive. Specifically, dried kenaf fibers can be used in the following aspects:
Textile industry: Dried kenaf fibers are softer and easier to weave, and can be used to make higher quality sacks, sackcloth, carpets, coarse canvas, curtains, wall cloths and other textiles.
Papermaking industry: Kenaf fibers are excellent raw materials for papermaking. Dried fibers are easier to make pulp for the production of various high-end books, picture albums, greeting cards, packaging boxes, handbags and other products.
Composite materials: Dried kenaf fibers can also be combined with other materials to make composite materials with special properties, such as fiberboard.
Agriculture and animal husbandry: The kenaf leaves can still be used as livestock feed after drying, and the kenaf stalks can also be used to make activated carbon, firecrackers, etc.
How to dry?
Preliminary cleaning of the kenaf after picking or harvesting to remove impurities and bad parts. Load the pretreated kenaf into the dryer evenly, taking care to avoid excessive accumulation to avoid affecting the drying effect. Start the dryer and heat and dry the kenaf through the hot air circulation system. The drying temperature and time should be adjusted according to the humidity of the kenaf and the required degree of drying. Generally speaking, the drying temperature should not be too high to avoid damaging the fiber quality, and the drying time should be long enough to ensure that the kenaf is completely dried. After drying, the kenaf is removed from the dryer and cooled. The cooled kenaf can be packaged, stored or further processed as needed.
