Is the Heat Dissipation Black Technology of Polyethylene Cooling Fiber Really Cooler Than Cotton?

As summer temperatures rise, the demand for breathable, cooling fabrics grows. While cotton has long been a staple for warm-weather clothing, polyethylene (PE) cooling fiber is emerging as a superior alternative—thanks to its advanced heat dissipation technology.

But does it really outperform cotton? Let’s examine the science, performance, and real-world benefits of PE cooling fiber compared to traditional textiles.

How Polyethylene Cooling Fiber Works?

PE cooling fiber achieves its ultra-cooling effect through two groundbreaking technologies:

1.The infrared rays (7-14um) ofthe Cooling PE fabric cmitted from human skin are neartytransparent and the transmittance is ove95%.Conventional textile materials such as cotton andpolyeste have a projection rate ofonly 1-396. That is, the Cooling PE fiber ilse is cool.

2.The heat transfer coefficient of Cooling PE/red fiberis the highes among the existing textilefiber, up to 0.42w/km, conventionz polyester and cotton at 0.07-0.08, and nylon at 0.22-0.28.Hic thermal conductivity indicates strong heat transfer and hee dissipation., cool down quickly.Due to these two unique performances of cooling PF/Red Fiher, th textile fabric/clothingdeveloped on the basis of this fiber can achie continuous and cxccllent cool feeling function.when worn on th human body whether lt is in the office orindoors, or walkin outdoors,ohthe one hand, there is no hindrance to the emission d infrared rays on the skin, and on the otherhand. it quickly guide away the heat ofthe skin. So it is an excellent choice for summer/hc days.

PE Cooling Fiber vs. Cotton: Performance Comparison

Why PE Fiber Feels Cooler in Real-World Use

·Indoors (Office/Home):

Unlike cotton, PE doesn’t trap body heat, keeping you cool without AC.

·Outdoors (Walking/Running):

Blocks solar heat while allowing skin heat to escape.

Wicks sweat faster, preventing sticky discomfort.

Additional Benefits of PE Cooling Fiber

✔ UPF 50+ Sun Protection – Blocks harmful UV rays better than cotton.

✔ Lightweight & Soft – More comfortable than traditional synthetics.

✔ Quick-Drying – Doesn’t retain moisture like cotton.

✔ Odor-Resistant – Reduces bacterial growth compared to damp cotton.

If you want scientifically proven cooling performance, PE cooling fiber is the best choice for summer wear, athletic gear, and outdoor clothing.
