Causes of growing mold in fabrics

Mold can grow both indoors and outdoors

Sometimes you may notice mold on your walls and tiles and don’t bother to pay attention to it. However, this matter shouldn’t be neglected. Like walls, mold can grow on your fabrics and affect your wellbeing. Surprisingly, mold can trigger allergic reactions and weaken the body’s immune system.

Two main factors behind mold growth are dampness and improper ventilation. Sometimes, you may prefer to store clothes in closet without drying them properly. As a result, mold attracts those wet clothes quickly in just 24 to 48 hours.

That’s why always try to air dry clothes properly. Or, throw them in dryers. But, most importantly, never leave your items in the washer for too long. As a rule of thumb, remove garments from washer as soon as the cycle finishes.

Humid weather is another reason behind mold growth. Therefore, always keep the humidity level of your house below 50%. Mold can grow massively in an above 50% humid environment.

Mold is a fungus that thrives on mainly moist organic materials. You may find them both inside and outside of your house. Their most common nesting places are leaks in pipes, roofs, windows. They may grow rapidly on wood, paper, cardboard, fabrics, upholstery, carpets, and wallpapers.

As mold develops in various conditions, you may observe them in different colors: white, green, orange, purple, and black. However, you might notice mostly white and sometimes greenish-black mold on fabrics.

Fabrics like cotton and linen are their favorite place to grow. So, always take special care of those items. Also, take quick remedial actions whenever you notice molds, as they may create holes in your clothes.
