Colloidal silica is used as a vital ingredient in many various chemical for formulations. One of the most well known areas is formulations for the textile industry.
Used alone or in combination with other ingredients, colloidal silica can provide frictionizing benefits by protecting the weave structure and improving improve seam slippage. There are also improvements to the dry hand and the control of fabric sheen.
Colloidal silica gives special finishing effects to blends and to fabrics made of cotton, wool, synthetic fibers and filaments. Textile finishers achieve outstanding results in dyeing and finishing using colloidal silica solutions.
