Product Details
1. Overview of PET Fiber Cotton Wick Stick
1.1 General introduction
PET fiber cotton wick is a porous liquid absorption rod made of composite thermoplastic fiber, with stable liquid storage and uniform volatilization performance. It matches water-based and oil-based essence, medicinal liquid and mosquito repellent liquid, widely used in aromatherapy diffusers, liquid mosquito repellent heaters, e-cigarette oil storage core and medical liquid volatilization equipment.
1.2 Chemical Composition & Microstructure
Two mainstream composite fiber formulas for selection:
- PA+PET type: 71% high-temperature resistant PA fiber + 29% low-temperature PET fiber
- PET+PET type: 71% high-temperature resistant PET fiber + 29% low-temperature PET fiber
Interlaced porous fiber structure, uniform tiny gaps inside for stable capillary liquid absorption, low expansion rate after long-term liquid soaking.
2. Manufacturing Process
2.1 Fiber Batching & Blending
High-temperature and low-temperature fiber raw materials are proportioned strictly according to formula, fully mixed to realize uniform fiber distribution.
Step A: High-speed fiber blending to avoid component agglomeration.
Step B: Extrusion molding into cylindrical cotton wick blanks.
Step C: Constant-temperature hot setting to fix internal porous structure.
Step D: Cooling shaping to maintain stable liquid absorption channels.
2.2 Precision Cutting & Finishing
Step A: Continuous cotton wick blanks cut into customized fixed lengths.
Step B: End surface trimming to remove loose burr fibers and prevent fiber falling off.
Secondary low-temperature shaping treatment to eliminate residual forming stress, avoid shrinkage during long-time heating volatilization.
2.3 Finished Sorting & Packaging
Screen cotton sticks with uneven density or loose fibers; sort products by diameter and length specifications. Qualified finished cotton wicks are packed for aromatherapy, mosquito liquid and electronic atomization manufacturers.
3. Core Performance Profile (Defining Feature)
3.1 Liquid Absorption & Volatilization Performance
- Ultra-light density range 0.04–0.7 g/cm³, porous structure with strong capillary absorption capacity for oil and water liquid.
- Low expansivity only 3%, no swelling deformation after long-time soaking in essential oil and liquid medicine.
- Consistent yarn diameter 15–20μm, stable uniform volatilization speed without sudden increase or decrease of fragrance output.
3.2 High Temperature & Chemical Compatibility
- Melt temperature reaches 250℃, stable structure under continuous heating of aromatherapy and mosquito liquid heaters, no melting collapse.
- Inert to most plant essential oils, alcohol-based medicinal liquid and oil-based mosquito repellent liquid, no chemical precipitation to block pores.
- No fiber decomposition or peculiar smell under long-term heating volatilization, pure volatile liquid without impurity pollution.
3.3 Physical & Structural Performance
- Fixed yarn gram weight 400D, uniform fiber tightness of each batch cotton stick, consistent liquid storage capacity of single piece.
- Soft interwoven fiber structure, no hard sharp edges, will not scratch internal equipment of diffuser heaters.
- Cylindrical uniform shape, matched with standard bottle inner diameter, no liquid leakage during liquid absorption and volatilization.
4. Key Limitations
- Not suitable for long-time contact with strong corrosive acid and alkali liquid, fiber structure will be damaged.
- Long-term use under temperature over 250℃ will lead to fiber melting and failure of liquid absorption function.
- Overly thick or ultra-thin customized diameter will slightly affect the uniformity of liquid volatilization.
5. Main Industrial Applications
5.1 Aromatherapy & Home Fragrance
Water-based & oil-based aromatherapy diffuser liquid volatilization cotton wick, household fragrance humidifier absorption stick.
5.2 Liquid Mosquito Repellent
Electric liquid mosquito repellent heater built-in volatilization cotton core, indoor mosquito liquid absorption stick.
5.3 Electronic Atomization Equipment
E-cigarette oil storage integrated cotton, portable atomizer liquid absorption core accessories.
5.4 Medical & Health Care
Low-concentration medicinal liquid heating volatilization absorption stick, aromatherapy medical atomization cotton wick.
6. Material Positioning
PET composite fiber cotton wick fills the demand gap between non-woven absorption strips and ceramic absorption cores. It balances low cost, stable liquid absorption and high temperature resistance, supporting both water-based and oil-based liquid media. Compared with single cotton fiber sticks, it has better heat resistance and smaller expansion deformation; compared with porous ceramic wick, it has lighter weight and lower unit cost, being the mainstream liquid volatilization absorption core material for household fragrance, mosquito repellent and small atomization equipment.
