Cotton bags are usually made of pure cotton as raw material, it is a kind of woven fabric that USES cotton yarn as raw material. Due to different organizational specifications and post-processing methods. Different varieties are derived. Cotton is wearing soft and comfortable, warm, moisture absorption, permeability is strong, easy to dyeing and finishing characteristics, due to the natural characteristics of it, is enjoyed by people already, become a indispensable basic things in life.

Currently, cotton bags are very popular internationally and cotton is the natural cotton. It has the characteristics of small, convenient, durable and pollution-free environment. The greatest benefit is the ability to reuse. Thus, the pollution of the environment is greatly reduced. It is environmentally friendly on raw materials. It can be degraded and has no pollution to the environment. It is also much stronger than non-woven fabrics, with fine print and fine print, which is better than non-woven bags.

Here are some of the advantages of cotton bags
1、hygroscopicity: cotton fiber has good hygroscopicity, under normal circumstances, around the fiber to absorb the moisture in the atmosphere, the moisture content of 8-10%, so it has contact with a person's skin, make the person feels soft and not stiff. If the moisture of cotton cloth is increased, the surrounding temperature is high, the water component of the fiber will evaporate completely, so that the fabric can keep the water balance, making people feel comfortable.
2、moisturizing: due to the cotton fiber is a poor conductor of heat and electricity, heat conduction coefficient is extremely low, and because of the cotton fiber porous, high elasticity, between fiber can accumulate a large amount of air, air is a poor conductor of heat and electricity, so the cotton fiber textiles have good moisturizing effect, pure cotton fabric dress makes people feel warm.
3、heat resistance: pure cotton fabrics can good heat resistance, the temperature of 0 degrees Celsius below 110 ℃, will only cause fabric on evaporation, water will not damage fiber, so pure cotton fabric, at room temperature in use, such as washing and dyeing of textiles have no effect, thus to improve the cotton fabric washing durability performance.
4、alkali resistant: cotton fiber of alkali resistance is bigger, cotton fiber in alkaline solution, the fiber damage occur, the performance is conducive to taking the pollution after washing, disinfection impurities, also can be carried out on the pure cotton textiles dyeing, printing and all kinds of processing technology, to produce more new cotton varieties.
