Kendo Cotton – What is it in Vaping?

Definition

Kendo Cotton is a premium, medical-gradeorganic cottonwicking material engineered specifically for rebuildable atomisers (RDAs, RTAs, and RDTAs). Harvested from pesticide-free cotton fields and purified through a multi-stage sterilisation process, Kendo Cotton offers exceptional e-liquid absorption and heat resistance. Its long, parallel fibres create capillary channels that deliver juice efficiently to your coil, eliminating dry hits while preserving flavour clarity. Unlike standard cotton balls, Kendo Cotton arrives pre-flattened in sheets, making it ideal for both cloud-chasing and flavour-focused vaping kits across Australia.

Technical Details

Each sheet of Kendo Cotton measures approximately 8 cm x 5 cm x 2 mm, weighing 0.8 g. The fibre density of 0.13 g/cm³ strikes the perfect balance between juice retention and saturation speed. Heat-resistant up to 280°C, it withstands high-wattage builds using Wire“>Kanthal wire or nickel coils without degradation. Two variants exist: Kendo Gold (ultra-white, faster wicking) and Kendo Vape Cotton (natural beige, longer lifespan). The cotton’s knurled surface texture increases surface area by 15%, enhancing flavour molecule capture. pH-neutral and free from bleach or chlorine, it maintains e-liquid integrity even with acidic fruit blends popular in Australia.

Usage & Tips

For optimal performance, tear Kendo Cotton along the grain, roll gently, and thread through your coil with minimal tension—aim for slight resistance when pulling back. Prime thoroughly with 3-5 drops of e-liquid before first fire. Common issues include break-in flavour (metallic taste for first 5 puffs) and over-stuffing (reduced airflow). If experiencing spitback, try Scottish-rolling the wick ends. Always wash hands before handling to prevent contamination. Store unused sheets in the resealable pouch away from direct sunlight—humidity above 60% may cause premature darkening, though this doesn’t affect performance.

History & Context

Originating from Japanese medical suppliers in 2015, Kendo Cotton revolutionised the rebuildable atomiser scene by addressing silica wick health concerns. Its adoption by Australian vape stores coincided with the rise of sub-ohmkits, quickly becoming the preferred wicking choice for drippers and Kayfun users seeking superior flavour. Today, it remains a staple in DIY coil-building communities nationwide.
