PU coating is a technology widely used in fabric processing. It can change the characteristics of the original fabric and give the fabric better performance and function. Compared with ordinary fabric, PU coating has the following differences.
First of all, PU coating can improve the waterproof performance of the fabric. For some outdoor sports clothing, raincoats, tents and other products that need to resist rain moisture, PU coating can form a waterproof film on the surface of the fabric, effectively resist rain penetration, and keep the surface dry.
Secondly, PU coating can improve the breathability of the fabric. Although waterproof is one of the main characteristics of PU coating, it does not completely close the fabric, making the fabric lack of breathability. On the contrary, PU coating can adjust the breathability of the fabric by means of micro-pores to maintain the comfort of the human body.
Third, PU coating can increase the wear resistance and durability of the fabric. Because PU coating itself has good wear resistance and durability, its application to the fabric can effectively increase the service life of the fabric. Especially for some parts that are easy to wear, such as the knees and elbows of the overalls, PU coating can play a protective role and reduce wear.
Fourth, PU coating can increase the antibacterial performance of the fabric. PU coating has certain antibacterial properties, which can prevent bacteria from growing and propagating on the fabric and reduce the breeding of taste. This is especially important for some clothing that needs to be worn for a long time, such as nurses' uniforms, overalls, etc.
Fifth, PU coating can improve the wind resistance of the fabric. In the cold season, the wind resistance of the fabric is particularly important for people in the field. PU film can form a layer of wind film on the fabric, effectively resist the cold wind attack, increase the thermal effect.
Sixth, PU coating can improve the anti-ultraviolet performance of the fabric. With the increase of ultraviolet light, the awareness of skin protection is becoming stronger and stronger. PU coating can form a layer of anti-ultraviolet film on the fabric, effectively reduce the penetration of ultraviolet light, protect the health of the skin.
In addition to the above differences, PU coating also has some other advantages. For example, PU coating can increase the softness and elasticity of the fabric, making the clothing more comfortable. In addition, PU coating can improve the crease resistance of the fabric and reduce creasing and wrinkling.
In short, PU coating is a technology that can change the characteristics of the original fabric, which can improve the water resistance, air permeability, wear resistance, bacterial resistance, wind resistance and UV protection of the fabric. Compared with ordinary fabrics, PU coating has more functions and better performance, making the fabric more suitable for different applications.
