Cotton bag is a very common type of jewelry packaging bag, which has the advantages of good quality and low price. Today we analyze the material characteristics of cotton bags and understand the characteristics of cotton jewelry bags.
1. Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, the fiber can absorb moisture into the surrounding atmosphere. Its moisture content is 8-10%, so it contacts human skin and makes people feel soft. Not stiff. If the humidity of the cotton bag increases and the surrounding temperature is high, all the water content in the fiber will evaporate and disperse, so that the fabric maintains a water balance and makes people feel comfortable.
2. Moisturizing property: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can be stored between the fibers. conductor.
3. Heat resistance: Pure cotton fabrics have good heat resistance. When the temperature is below 110 ° C, it will only cause the water on the fabric to evaporate and will not damage the fibers. No effect, which improves the washing and wearing resistance of cotton fabrics.
Cotton bags have many characteristics and are very suitable for storing some high-demand items, so cotton bags are used in jewelry packaging bags a lot.
