The leaves of jute are ovate or narrowly lanceolate, with an acuminate apex, a rounded base, and finely serrated margins. The flowers are arranged in axillary cymes, with yellow, obovate petals. The capsule is globose, with an apex that is hornless but has longitudinal ridges and tuberculate protrusions. The flowering period is from July to September, and the fruiting period is from September to November. The plant gets its name from the golden, silky luster of its fibers.

Soybean fiber is produced using soybean meal (a byproduct of oil extraction) or food-grade soy protein powder as raw materials. Through biotechnological engineering, globulin is extracted from these materials, followed by the addition of functional additives. The globulin is then subjected to grafting, copolymerization, and blending processes with high polymers such as nitrile groups and hydroxyl groups to form a protein spinning solution with a specific concentration. Finally, soybean fiber is manufactured through a wet spinning process.
