The most developed nanotechnology application for textiles is in the area of finishes. It has opened immense possibilities in this area resulting in innovative new finishes as well as application techniques.

Nanofinishesare generally applied in nanoemulsion form, which enables a more through, even, and precise application on textiles surfaces. They are generally emulsified into either nanomicells,made into nanosols or wrapped in nanocapsules that can adhere to textile substrates easily and more evenly.

Majority of the yarns produced commercially today are plain yarns whose quality standards are judged on the basis of good uniformity %, higher strength, less imperfections, evenness of colour, texture etc. At some point,the fabric designers realized that a nice attractive effect can be produced in fabrics by playing with imperfections, colours, uniformity & other properties of the yarns.
