What's the difference between cotton and polyester

Usually for work polo shirts or staff uniform shirt. We know there are two materials: Cotton and polyeter. Now let's get their difference: 

1. Different States after combustion

When cotton burns, the flame is smooth. Take a small amount of fibers to ignite and observe the ash left behind. If it is loose, the cotton will break up in one twist. On the contrary, if it melts first, then it forms aggregated solid bonded together, it is polyester

2. Different absorption effects

Cotton hydrophilic, polyester hydrophobic. Cotton absorbs water much better than polyester.

3. Different gloss

By looking at the gloss to feel, if the reflection is very bright, it is basically polyester.

Function of Cotton Material

1. Hygroscopicity

Cotton fiber has good hygroscopicity. Under normal conditions, it can absorb water into the surrounding atmosphere. Its moisture content is 8-10%, so it touches human skin and makes people feel soft but not stiff. If the humidity of cotton cloth increases and the surrounding temperature is higher, the water content in the fiber will evaporate and dissipate, which will keep the fabric in a state of water balance and make people feel comfortable.

2. Warmth retention of pure cotton fabrics

Because cotton fiber is a bad conductor of heat and electricity, its thermal conductivity is very low, and because cotton fiber itself has the advantages of porous, high elasticity, a large amount of air can be stored between fibers, and air is a bad conductor of heat and electricity, so pure cotton fiber textiles have good warmth retention, wearing pure cotton clothing makes people feel warm.

Function of Polyester

1. Polyester fabrics have high strength and resilience, so they are durable, wrinkle-resistant and ironing-free.

2. Polyester fabrics have poor hygroscopicity, suffocating feeling in summer, static electricity in winter and affecting comfort. However, after washing, it is easy to dry, and the wet strength almost does not decrease. It does not deform and has good washability and wearability.

3. Polyester is the best heat-resistant fabric in synthetic fabrics. It has thermoplasticity and can be made into pleated skirts with long pleats.

4. The light resistance of polyester fabric is better than that of natural fiber fabric except acrylic fiber. Especially in the back of the glass, the sun resistance is very good, almost equal to that of acrylic fibers.

5. Polyester fabrics have good chemical resistance. Acids and alkalis do not destroy it to a great extent, and they are not afraid of moulds and moths.
