A new source of natural fiber in Bangladesh

The horizon of diversified uses of natural fibers are in increasing trends due to their ecofriendly, biodegradable, re-cyclic and reusable characteristics properties. Recently different studies have been undertaken to find out new sources of nonconventional natural fiber.

Sansevieria Trifasciata is a long leafy wild plant, 70 species of them are available.

A proximate study on different physical and chemical properties along with composition and dyeability of fibers were performed with standard laboratory condition in Textile Engineering Department, Primeasia University (PAU).

The study was conducted by Md. Sabbir Hasan, Md. Ahsanul Kabir Oyon, Md. Torikul Islam of Textile Engineering Department, Primeasia University. And supervised by Prof. Dr. A.B.M Abdullah.

Before that fiber were extracted from the leaves by ChemiBiochemi-Mechanical accelerated retting process developed in dying lab PAU.

This proximate study and analytical results indicate the possibility of using this lignocellulosic fiber as textile fiber; woven, non-woven, knitted, blended, composite, pulp/paper, sources of alpha-cellulose, microcrystalline cellulose, nano-cellulose, cellulose derivatives and lignin-based commercial products.

Sansevieria Trifasciata plant is native to India, Indonesia and Africa. It is evergreen and perennial. Its leaves grow vertically from basal rosette. Leaves are stiff sword-shaped.

Matured leaves are deep green with light grey-green. Its leaves are thickened and fibers are laminated with green waxy membrane. Presently this plant is urbanized as a decorative garden plant for their air purification characteristic property and conversion of CO2 into O2 at night.

Indigenously it is called in different names as ‘Mother-in- law’s tongue’, ‘Saint George’s sword’, ‘Snake plant’ or ‘Bowstring hemp’ in our locality it is called ‘Bhaghachokor’ and it is widely found in different areas of Bangladesh.

2kg matured green plants were collected from garden of Fokir Bari, Dewna, Kapasia, Gazipur.
