Is the sweatshirt front air dried or back air dried? What is the sweatshirt for

It is recommended to air dry the back of sweatshirts to reduce fabric damage and extend their lifespan. Sweatshirt is a type of sports accessory clothing that accelerates sweating through special materials, mainly used for short-term exercise to lose weight or for quick dehydration and weight control before competition. Sweat jackets usually use waterproof breathable membranes and polyester fiber composite fabrics. Drying the back can prevent the outer waterproof coating from being directly exposed to sunlight and oxidation, while reducing the elasticity decrease of the inner moisture absorbing fibers caused by direct ultraviolet radiation. Exposure to direct sunlight on the front side in high temperature environments may cause the adhesive strip at the joint to crack, while hanging on the back side can allow moisture to evaporate evenly from the inner layer, avoiding local overheating and deformation. Some styles with reflective strips need to be air dried on the back to prevent the pattern from fading. professional athletes often use sports grade sweatshirts with silver ion coatings, and the back side can be air dried to protect the antibacterial layer from damage. Although daily fitness products have lower requirements for air drying, long-term frontal exposure can still accelerate fiber aging. After cleaning, avoid using a dryer. When hanging, completely flip out the lining to ensure that the thickened areas such as armpits and waist are fully ventilated.

After using sweatshirts, sweat stains should be cleaned in a timely manner, and it is best to choose neutral detergent for hand washing. When storing, keep them dry to avoid mold growth. Moderate hydration is necessary during exercise, and a single wearing should not exceed 90 minutes. Patients with cardiovascular diseases and pregnant women should avoid using it. A properly maintained sweatshirt can maintain an effective service life of about 200 hours. It is recommended to check the sealing and breathability of the clothing every quarter.
