Technology to Dye Cotton Fabric and Yarns with Lac Dye

Description and salient Technical features

Lac dye is recovered from the lac processing waste water. This natural dye can be easily obtained in 100 tonnes or more quantities annually. Though there is a good demand for natural dyes now a days due to their eco-friendly nature, demand for this dye was poor as it could dye only wool and silk but not cotton and other cellulosics.

Synthesis of Monodisperse Nano Zinc Oxide Particles by a Novel Chemical Route

Description and salient Technical features

A novel chemical process was developed at CIRCOT for the preparation of zinc oxide nanoparticles by using zinc nitrate and sodium hydroxide precursors. Soluble starch is used as stabilizing agent. The concentration of soluble starch is a major factor that decides the size of the nanoparticles. These nanoparticles can be applied on to cotton fabrics to impart antibacterial and UV-protection functions.

Particle Board from Cotton Stalk

Description and salient Technical features

Cotton plant stalk is a renewable agrowatse material, available to the extent of about 30 million tonnes annually in our country. At present it is not being used for any commercial purposes, except as fuel by the rural masses, while the bulk of the stalk is disposed off by burning in the field itself. Technology was developed for preparation of particle boards from cotton stalks.
