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.

Highlights

Almost all regions of Indonesia are pineapple-producing regions (Ananas comosus [L.]) because they are supported by tropical climatic conditions
The results showed that natural dyes type had an effect on the color intensity values of L*, a* and b* in pineapple leaf fibres
The highest average L value of pineapple leaf fibres was 59.73 (S), while the lowest was 41.40 (C). This finding explained that the pineapple leaf fibres which was colored by suji leaf extract had higher brightness compare to the other two natural dyes

Summary

Introduction

Almost all regions of Indonesia are pineapple-producing regions (Ananas comosus [L.]) because they are supported by tropical climatic conditions. Indonesia is the third largest pineapple producer after Philippines and Thailand with a contribution of around 23% in Southeast Asian region [1]. Farmers in Indonesia utilize agricultural waste in the form of leaves from pineapple production to be used as fertilizer and animal feed, while fibre parts which has a high enough value in terms of its function and economic value can be taken from pineapple leaves [2]. Cellulose content in pineapple leaf fibres is quite high compared to other natural fibre sources which reach 85% and only lower than hemp cellulose content by 91%. Pineapple leaf fibres is white in color, smooth and glossy as silk [5]
