Study of Natural Dyes and Pineapple Leaf Fibres Growing Locations within Plant Stems on Dyeing Intensity.

Abstract

The physical properties of fibres produced from pineapple leaves can vary due to the differences in growing locations within a stem and are influenced by leaf growth age. Pineapple leaf fibres require quality increase, particularly in dyeing. The utilizing of natural dyes ingredients from suji (Dracaena angustifolia) leaves extract, turmeric (Curcuma domestica val) and sappan (Caesalpinia sappan [L.]) wood have friendly impact on the environment. Various types of natural dyes and leaf fibres growing location within the stems of pineapple plants and the color intensity are carefully examined in this study. The diversity of natural dyes used in dyeing influenced the fibres color intensity of pineapple leaves. Pinneaple leaf fibers growing loccation within pineapple stems impacted fibre color lightness intensity, the axis a∗ and b∗ colors. The utilization of pineapple leaf fibers from the base of plant stem is more suitable to be used as textile raw material due to its higher lightness level.
