Abstract

Chemical treatment of cellulosic fabrics to alter the fibers properties without changing their fibrous form is a common practice nowadays in the textile industry. In this paper cotton (woven and knitted) fabrics are selected and reacted with sodium hydroxide, morpholine, and cellulase enzyme. The fabrics are then dyed by some selected dyes such as annatto, onion, pomegranate, indigo, myrobalan, bar berry (natural dyes); and reactive and sulphur dyes (synthetic) respectively and subsequently finished. These fabrics are then analyzed for mechanical and surface properties from KES-F, and assessed by SEM and FTIR.

Highlights

Today cotton is the most used textile fiber in the world [1]
Primary hand value (PHV) of dyed and finished cotton fabrics: The parameters evaluated from KES-F of dyed and finished cotton fabrics for the primary hand value of woven and knitted fabrics are given in Table 1a and 1b respectively
The primary hand value is maximum for the sodium hydroxide treated [2] fabrics followed by morpholine treated [3], enzyme treated [4] and untreated [UT, 1] dyed [F1] and finished [F2] woven and knitted cotton fabrics (Table 1a and 1b)

Summary

Introduction

Today cotton is the most used textile fiber in the world [1]. World textile fiber consumption in the end of 20th century was approximately 45 million tons. Of this total, cotton represented approximately 20 million tons [2]. Cotton is a natural product [4] and nonallergic since it doesn’t irritate sensitive skin or cause allergies. Cotton has a high absorbency [5] rate and holds up to 27 times its own weight in water. Cotton swells in a high humidity environment, in water and in concentrated solutions of certain acids, salts and bases [6]. Chemical treatment of cotton cellulose to alter physical properties of the fibers without changing their fibrous form is a common practice in the textile industry [7]
