Natural Dyeing of 3 Different Grades of Silk Yarns Using Musa acuminate and Analysing of Dyed Silk Yarn by Colourfastness, Spectrophotometer & FTIR

Abstract

The natural dyeing of silk yarn and an investigation of its characteristics are the main topics of this work. Natural yarns are renewable, sustainable, biodegradable, and biorefinery, making them environmentally benign. One of the earliest natural animal protein fibres, silk thread is derived from the cocoons of silkworms and is widely used in textiles. Silk strands, which are used to make fabrics, are known for their tensile strength and glossy qualities. This test's objective is to ascertain the chosen silk yarns' quality, strength, durability, air flow, and covalent chemical bonding throughout the yarn stage. The classified silk yarns are then put through spectrophotometer and FTIR analysis tests to determine their colourfastness.
