Geek Bar: Four criteria for selecting high-quality cotton core materials
The primary basis for creating a good cotton core electronic atomization product is the scientific selection of cotton fiber materials. In this regard， Geek Bar Research Institute has carried out long-term and in-depth basic scientific research. The study found that not all cotton fiber materials can be used for the production of electronic atomizer cotton cores. Excellent cotton fibers must meet the following conditions:
1. Large fiber cavity
Mature and normal cotton fibers have irregular waist-shaped cross-sections with a middle cavity. Cotton fibers with a larger middle cavity have good oil retention and can store more atomized liquid， locking the liquid firmly in the cotton core， effectively reducing the chance of leakage.
2. Dense side grooves on the fiber side
Cotton fibers have natural twists， and the irregular spiral twists that continuously change the direction along the length of the fiber form side grooves. Cotton fibers with dense side grooves have good capillary climbing rate and good oil conductivity. They can continuously guide the atomized liquid to the vicinity of the heating wire， so that the effective ingredients are evenly and efficiently transferred to avoid dry burning.
3. High temperature resistance
Due to differences in variety， origin， composition and process， cotton fibers show different temperature resistance. High-quality cotton fibers can maintain their properties under high temperature conditions， which can effectively overcome pain points such as core burning and severe taste attenuation， greatly improve the stability of taste， and extend the service life of the product.
4. Fiber purity
Fiber cleanliness is another important factor in selecting cotton fibers. Pure cotton fibers can avoid local burning caused by uneven heating due to inconsistent material properties， making the taste more restored and the experience consistent； the source of the material is safe and controllable， and no harmful substances will be introduced， let alone the risk of powder loss.
Geek Bar Research Institute has conducted long-term high-precision testing and user experience tracking on the capillary wicking and oil holding， oil conduction performance， and temperature resistance of various types of fiber materials， and established a database of oil conduction materials in 6 categories， including cotton， linen， cellulose， organic， inorganic， and synthetic， so as to achieve targeted material selection， break the industrys blind selection practice， and lay a solid foundation for a good user experience.
As a veteran who has been deeply involved in the atomization industry for 12 years， we have always insisted on innovation-driven development and that science and technology are the primary productive forces. We have the responsibility to assume the obligation to use science to legislate for cotton cores， directly addressing market pain points and allowing people to experience cotton core electronic atomization products that are pure in taste， healthy and safe.
