When processing fabrics there are a number of chemical treatments you can apply to them to improve their properties. Pre-dyed polyester and polypropylene fabrics have these treatments applied with a surface binder, but polyamide fabrics during the dyeing and finishing process can actually get these treatments pressure injected in to the yarn itself for longevity.Any of the treatments below used on our fabrics will be shown in the technical section of the product listings.HYDROPHILICA Greek term meaning 'water loving'. These treatments help to transport moisture through a fabric and increase the level of spread. This speeds up the wicking rate and provides a high surface area for evaporation to occur on the outer fabric layer. Hydrophilics used in Sub Zero fabrics do not alter the handle of the material.HYDROPHOBICA Greek term meaning 'water hating'. These treatments actively repel moisture and are used usually on the outside of a fabric as a water repellent i.e. waterproof.ANTI-MICROBIALThere are a wide range of different treatments that fall in to this category but they all protect fabric and garments against both harmful and odour-causing bacteria. This enables clothing to be washed at cooler temperatures and also increases the uses between washes.ANTI-MOSQUITOThese are basically insecticidal treatments that can be applied to fabrics. The most common and widely used chemical is Permethirn, a synthetic pyrethroid based on the chrysanthemum flower.ANTI-STATICThe build up of static electricity in synthetic fabrics can be a major problem for industrial and military applications. An anti-static application helps to increase the conductivity of the fabric, greatly reducing/eliminating static build-up.TEFLONTEFLON is trademark for Polytetrafluoroethylene (PTFE). You will probably know it as a non-stick coating applied to frying pans but it has a multitude of uses. As a fabric treatment, it repels water and dirt, as well as providing a soft handle.
