Abstract

The objective of this research work was to investigate the effect of intermingling process parameters on melange fabric appearance. Results show that the polyester overfeed, nylon overfeed, air pressure, and production speed have significant correlation with melange fabric appearance. Polyester yarn tension and nylon yarn tensions do not show significant effect on melange fabric appearance. Melange appearance varies from stripe to uniform distribution when polyester and nylon overfeeds are increased independently as well as collectively. Therefore, it can be concluded that polyester and nylon overfeed can be used to achieve specific melange appearance as per the customer samples. Optimum air pressure and production speed to be determined during sample development stage since those two parameters are directly link to the production cost; and should be maintained as a constant and controlled during production, since any variation of those two parameters will change appearance of the melange fabrics.

Highlights

Introduction and literature reviewMelange is a coloured effect achieved by cross dyeing yarn or fabric made from more than one type of fibres or filaments
It is expected that the colour intensity increases when the Nylon overfeed is increased while polyester overfeed keeping constant
Dyed area percentage decreases when the Polyester overfeed is increased while keeping nylon overfeed constant

Summary

Introduction

Introduction and literature reviewMelange is a coloured effect achieved by cross dyeing yarn or fabric made from more than one type of fibres or filaments. The process involves dyeing yarn or fabric using different dyes chosen for their affinity to the fibres so that each fibre type will only absorb certain dyes. This produces a fabric that has subtle variations in colour an appearance known as melange effect. The demand for melange fabrics keep growing because its special effect adds value to the garment’s aesthetic appearance This trend has been growing across many applications, such as office wear, casual wear, active wear, outerwear, fleece and woven to light weight garments, making it flexible fashion solution for wide range of apparel products. It adds value to the fabric, which gives the garment a higher perceived
