The blend ratio of terylene and cotton in TC Camo Fabric plays a significant role. Polyester is naturally more resistant to mildew compared to cotton. Polyester fibers are hydrophobic, which means they repel water. Since mildew needs moisture to grow, the polyester in the TC blend helps create an environment that's less friendly to mildew.
On the other hand, cotton is hydrophilic. It absorbs and retains moisture, providing a perfect breeding ground for mildew. So, if the TC fabric has a higher percentage of cotton, it might be more prone to mildew growth. For example, a TC fabric with a 65/35 blend (65% polyester and 35% cotton) will generally be more mildew - resistant than a 35/65 blend.
Finishing Treatments
Many TC Camo Fabrics go through finishing treatments to enhance their properties. Some of these treatments can improve mildew resistance. Anti - mildew finishes are commonly applied to the fabric during the manufacturing process. These finishes work by either creating a physical barrier on the fabric surface or by releasing chemicals that inhibit the growth of mildew.
There are different types of anti - mildew finishes. Some are based on silver ions, which have antibacterial and antifungal properties. Others use organic compounds that are toxic to mildew but safe for humans. These finishes can significantly increase the fabric's ability to resist mildew, even in high - humidity conditions.
Storage and Usage Conditions
Even if a TC Camo Fabric has good inherent mildew resistance or has been treated with anti - mildew finishes, how it's stored and used can still affect its susceptibility to mildew.
If the fabric is stored in a damp, dark place, like a basement with poor ventilation, mildew is more likely to grow. Similarly, if the fabric gets wet during use and isn't dried properly, mildew can start to form. For example, if you're using TC Camo Fabric for outdoor gear like tents or backpacks, and they get soaked in the rain but are then packed away wet, you're asking for trouble.
On the flip side, if the fabric is stored in a dry, well - ventilated area and is allowed to dry thoroughly after getting wet, the chances of mildew growth are much lower.
