- Sun hemp cultivation involves planting, growth, and fiber extraction processes.
- Once the plant reaches maturity, the stems are harvested and processed for fiber extraction.
- The fibers undergo cleaning, carding, and spinning processes.
3. Applications:
- Sun hemp fibers are primarily used in rope making, twine, and cordage applications.
- They are also utilized in the production of fishing nets, upholstery, and geotextiles.
4. Sustainability and Challenges:
- Sun hemp is a sustainable crop as it enriches the soil with nitrogen and requires minimal pesticides.
- Challenges include limited awareness and market demand for sun hemp fibers.
V. Cannabis Fiber:
1. Definition and Characteristics:
- Cannabis fibers, commonly known as hemp fibers, are derived from the Cannabis sativa plant.
- They are known for their strength, durability, and antimicrobial properties.
- Hemp fibers can be beige, brown, or gray in color.
2. Production and Processing:
- Hemp cultivation involves planting, harvesting, and retting processes.
- Retting is performed to separate the outer bark from the fiber-rich core.
- The fibers are then cleaned, carded, and spun.
3. Applications:
- Hemp fibers have diverse applications, including apparel, accessories, and home textiles.
- They are also used in the production of paper, composites, and insulation materials.
- Hemp's sustainability and versatility make it an attractive choice for eco-conscious consumers.
