Promoting natural fiber from bark of Hibiscus tiliaceus as rope to reduce marine pollution from microplastic fiber yield from synthetic rope
AI summary Read the abstract
Researchers characterized natural fiber rope made from the bark of Hibiscus tiliaceus as a potential sustainable alternative to synthetic ropes used in marine applications. They found that the natural fiber ropes had competitive mechanical properties and offer the advantage of biodegradability, potentially reducing synthetic fiber pollution in marine environments. The study supports development of marine-grade natural fiber products.
Synthetic ropes are popular for application in marine boat as docking, anchor, tow, and sailing. The advantages of synthetic ropes are waterproof, strong and durable, can be designed for sinks or floats and able to stretches. Synthetic ropes are stronger, more resistant to rotting than ropes created from natural fibers. Synthetic ropes also possess certain disadvantages of slipperiness, and can be damaged more easily by UV light. Synthetic ropes is recognizes as a source of microplastic fiber pollutant in marine area. In this work a bark of Hibiscus tiliaceus three is introduced as candidate source of natural fiber for rope to reduce number of microplastic fiber pollutant from synthetic rope. The bark was taken from a trunk with diameter around 20 cm. The bark was immersed in water for 7 days and subsequently was soaked in 5% NaOH solution for 2 hours. Fiber obtained then was dried. It was prepared 7 valid single fiber samples. The average of tensile strength of single fiber obtained by using this method is found around 44.604 MPa. The average of Modulus elasticity E is found 365.864 MPa. The failure strain is found 11.6 %.

Degradation of synthetic and wood-based cellulose fabrics in the marine environment: Comparative assessment of field, aquarium, and bioreactor experiments.
AI summary Read the abstract
This study examined how quickly synthetic and wood-based cellulose textile fabrics degrade in the marine environment and how many microfibers they release. Researchers found that wood-based cellulose fabrics broke down much faster than synthetic fibers like polyester, shedding fewer persistent microfibers. The findings support a shift toward natural cellulose textiles as a more ocean-safe alternative.
