Textile manufacturing processes can produce harmful environmental impacts, particularly the generation of significant textile waste.Thus, in this study, researcher examined the potential of the needle felting technique as a method for reusing textile wastes.Needle felting is a unique textile technique that involves the interlocking of fibres using a barbed needle.This process can be used to transform fabric wastes into new fabrics without the need for spinning or weaving.Furthermore, natural dyes derived from plants such as Parkia speciosa pods can provide an eco-friendly alternative to synthetic dyes, thus reducing the environmental impacts of textile production.Accordingly, exploring the use of cotton wastes from a cotton-weaving factory in Thailand to develop a sustainable material for clothes through the application of needle felting and natural dyeing using Parkia speciosa pods.Moreover, the colour, weight, thickness, texture and colourfastness of needle-felted bitter-bean-pod-dyed cotton wastes were evaluated before and after the needle-felting process.The fabrics' colour strength (K/S values) and weight (grams per square meter) were also assessed to determine the correlation between fabric weight and colour strength.Additionally, colourfastness to dry cleaning, washing, rubbing, light and perspiration was evaluated.Results showed that needle felting is a feasible technique for transforming textile waste into new, durable fabrics.The research further revealed that cotton wastes can be successfully dyed using natural colours, offering a sustainable alternative for prospective textile applications in the future.
