Abstract

Organic cotton is grown using methods and materials that have a low impact on the environment. Organic cotton is grown and processed without toxic chemicals that can be absorbed easily when in contact with the user\'s skin. This paper describes the dyeing behavior of organic cotton vs conventional cotton to find what will be the significance between them. The ring spun yarns of 40s combed organic (GOTS certified) and ordinary cotton were produced with similar parameters like beating point and settings. Knitted fabrics were produced with similar loop length and weight using organic and ordinary cotton yarn. Both the fabrics were processed in GOTS certified Processing unit using reactive dyes in soft flow machine in single dye bath. Processed fabrics were tested for colour fastness to washing, water, rubbing, perspiration and light. Colour difference and strength were also measured using Spectrophotometer (DATACOLOUR). Presence of metals were also analyzed in both the processed fabrics and reported here. Keywords: Organic cotton, dyeing, fabrics, textile.

Highlights

Around the world, more toxic insecticides are used on cotton than on any other crop
The farmers have only a chance to convert their production into a controlled organic cultivation of organic cotton is grown using methods and materials that have a low impact on the environment
With respect to insect control in particular, a thorough knowledge of non-chemical means of insect control is a pre-requisite for organic production

Summary

Introduction

More toxic insecticides are used on cotton than on any other crop. A sustainable alternative is the certified organic cultivation of the “white gold”. Organic cotton is grown and processed without toxic chemicals that can be absorbed when in contact with the user's skin. Pesticides, fertilisers and chemicals used to grow and process conventional cotton fabrics may go directly to the users blood stream, which affects the body's organs and tissues. The naturally soft organic cotton fabric is a lot more comfortable to use and is available at competitive prices.
