            Introduction to textile fibers

            Objectives: At the end of this lesson you shall be able to
            •  explain textile fibers
            •  list characteristics of textile fibers
            •  brief classification of fibers
            •  explain the identification of textile fibers by using different methods.

            •  Flexibility: Fibers need to be pliable and able to bend   •  Density: Mass per unit volume.
               without breaking.                                  •  Flammability: How easily a fiber ignites and burns.
                                              Classification of textile fibers (Fig 1)


























            Textile fibers are broadly classified into two main     •  Seed/fruit fibers:  Cotton, Kapok, Coir (from
            categories:                                                coconut).
            1  Natural fibers: These fibers are derived directly from   •  Bast/stem fibers: Flax (for linen), Jute, Hemp,
               natural sources.                                        Ramie.
               •  Plant-based  (Cellulosic)  fibers:  Composed      •  Leaf fibers: Sisal, Abaca (Manila hemp).
