by Origin and Cultivation of Abaca
The abaca plant, also known as Manila hemp, belongs to the genus Musa and species Musa textilis. It is native to the Philippines and Indonesia. Abaca is primarily cultivated in the Philippines, where it grows abundantly along river valleys and in marshy lowlands. The plant thrives well in tropical climates and requires a rainfall of at least 100 inches annually for good growth. Abaca prefers well-drained, loose soils rich in organic matter for optimum yields. It takes 15-24 months for an abaca plant to reach flowering stage and around 4-5 years to attain full maturity. Commercial harvesting is done by manually cutting the flower stalks once the plants mature. After harvesting, the leaves are removed and stalks are retted to extract the fibers.
Physical and Chemical Properties of Abaca Fiber
Abaca Fiber is renowned for its tenacity, strength and durability. It is the hardest and strongest natural fiber after ramie. On an average, Manila hemp is composed of 71-75% cellulose, 21-23% hemicellulose and 1-2% lignin. It has high wet strength, good flexural properties and low moisture absorption capacity of only 12%. Manila hemp is resistant to damage from seawater, acids, alkalis and microorganisms. However, it is prone to damage from sunlight. Chemically, Manila hemp consists mostly of polymers of glucose known as cellulose. This molecular structure and composition gives abaca its excellent mechanical properties and durability.
Uses of Abaca Fiber
Due to its remarkable strength, resilience and flexibility, Manila hemp finds a variety of industrial applications. Some major uses of abaca include:
– Cordage and Twines: Abaca is a premier fiber for making ropes, twines, wrappings and other cordage products used in shipping, fishing and rigging industries. Manila ropes produced from abaca exhibit superior durability and knot strength.
– Paper Products: Abaca pulp allows production of high-quality writing, printing and specialty papers. It enhances paper strength, opacity, folding endurance and printability.
– Composites: Fiber reinforced abaca composites exhibit high specific strength and are used in construction, automotive and aerospace industries for making lightweight structural products.
– Textiles: Abaca fabric is breathable and has a texture similar to linen. It is used for making durable shirts, uniforms, tents and home furnishing fabrics.
– Specialty Products: Manila hemp finds applications in cigarette filters, banknotes, braided insulation sleeves, mechanical gears, gaskets and mattress stuffing due to its mechanical resilience.
Advantages over Other Natural Fibers
Abaca offers several advantages compared to other natural fibers:
– Strength: It has exceptionally high tensile strength, often double that of cotton or flax fibers. Breaking strength of abaca can exceed steel and aluminum on weight basis.
– Durability: Abaca ropes last 3-4 times longer than man-made fibers under continuous wear and stress. The fiber resists damage for several years outdoors.
– Low Stretch: Abaca has very low elasticity of only 2-4% compared to 20-30% for cotton or flax. This makes it suitable for applications requiring dimensional stability.
– Buoyancy: Being relatively water resistant, objects made from abaca float easily and retain their shape when wet.
– Biodegradability: Unlike synthetic polymers, abaca is environment-friendly and biodegrades over time without harming soil or water bodies.
Processing and Manufacturing of Abaca Products
Raw abaca stalks go through various processing stages before final products. The main steps involved are:
– Retting: Soaking harvested stalks in slow-moving water to separate fibers from lignocellulosic particles via microbial degradation.
– Decortication and Scraching: Mechanically removing outer bark/rind using knives or hackles to extract soft inner fibers.
– Drying: Sun drying or using dryers to reduce moisture content below 12% for storage and spinning.
– Sorting and Grading: Separating fibers based on length, quality and strength specifications.
– Baling and Packaging: Compressing sorted fibers into uniform bales for shipping and storage.
– Spinning: Twisting fibers into yarns using machines or manual spinning wheels.
– Weaving, Knitting and Braiding: Converting yarns into fabrics, cords and structural shapes.
– Dyeing and Finishing: Imparting color and surface properties like water resistance.
Thus, Manila hemp is processed through integrated refining techniques before conversion into commercial products and applications. Proper harvesting, retting and manufacturing procedures help realize the full potential of this amazingly strong natural material.
