Spinnerets are the heart of fiber production, responsible for forming thousands of precision micro-holes that determine the final fiber thickness, strength, and quality.
But when polymer residues, carbon deposits, or high-viscosity materials accumulate inside these micron-sized holes, production quality can drop dramatically.
This is where the Spinneret Cleaning Furnace becomes essential β especially for nonwoven, meltblown, and polymer fiber manufacturers.
In 2025, leading factories worldwide are upgrading to vacuum pyrolysis-based spinneret cleaning systems to ensure maximum uptime and perfect fiber uniformity.
This comprehensive guide explains why this technology is now the global standard.
π What Is a Spinneret Cleaning Furnace?
A spinneret cleaning furnace is a specialized thermal cleaning system designed to restore spinnerets, filter packs, and precision fibre-producing components to like-new condition.
It uses a controlled, three-stage vacuum cleaning process:
β Melting
Softens and drains polymer residues at ~320Β°C.
β Pyrolysis (Vacuum Decomposition)
Breaks down remaining polymer at β0.085 MPa with zero oxygen damage.
β Controlled Oxidation
Removes carbon and micro-residue, leaving holes completely clean.
This process ensures spinnerets remain free from:
- PP, PET, PA polymer buildup
- Carbonized residue
- Burnt material
- Micron-level blockage
π§ Why Spinnerets Must Be Cleaned With a Vacuum Pyrolysis Furnace (Not Chemicals or Torches)
Nonwoven and meltblown spinnerets have extremely delicate holes, often 0.10β0.30 mm, meaning even the smallest deformation destroys fiber quality.
Hereβs why traditional cleaning methods fail:
β Torch or flame cleaning
Burns carbon, enlarges holes, ruins geometry.
β Chemical cleaning
Can corrode stainless steel and requires hazardous waste disposal.
β Ultrasonic baths
Cannot remove deep-blocked polymer inside long micro-holes.
β Manual scraping
Impossible for micron-sized spinneret holes.
A vacuum spinneret cleaning furnace is the only system that:
β protects hole shape
β cleans all micro-holes evenly
β avoids oxidation
β ensures consistent fiber diameter and GSM
β is fully automatic and operator-safe
β Key Benefits of a Vacuum Spinneret Cleaning Furnace
1οΈβ£ Protects Micro-Hole Precision
The vacuum environment prevents oxidation, guaranteeing the spinneretβs tiny holes remain unchanged.
2οΈβ£ Completely Removes Polymer Residue
Even stubborn PET, PA, PP residues are fully decomposed.
3οΈβ£ Extends Spinneret Lifespan
Factories report 2Γβ3Γ longer service life with vacuum cleaning.
4οΈβ£ Improves Fiber Quality & Stability
Cleaner holes = better melt flow β consistent GSM β fewer defects.
5οΈβ£ Increases Production Uptime
Cleaning cycle is fully automatic β reduces downtime by up to 80%.
6οΈβ£ Safe, Clean, and Eco-Friendly
Optional water scrubber ensures no smell, no smoke, no emissions.
π Who Needs a Spinneret Cleaning Furnace?
This system is essential for:
β Nonwoven (Spunbond / Meltblown) Production Lines
Maintains high-quality meltblown fabric, SMS fabrics, medical-grade materials.
β Chemical Fiber Factories
Improves nylon, polyester, polypropylene fiber consistency.
β Filtration and Polymer Extrusion
Restores spinneret and die precision for clean melt flow.
β Maintenance Service Centers
Provides standardized cleaning services for multiple plants.
π¬ How the Furnace Works (Simple Explanation)
πΈ Phase 1 β Melting
Heat gradually melts most polymer deposits β drains into a collector tray.
πΈ Phase 2 β Vacuum Pyrolysis
Under β0.085 MPa vacuum, polymer decomposes into vapors β scrubbed by a water system.
πΈ Phase 3 β Controlled Oxidation
Remaining carbon residue turns into ash β leaves spinneret bright and clean.
The result?
360Β° clean, residue-free micro-holes.
π Global Market Demand for Spinneret Cleaning Furnaces (Based on Industry Analysis)
Demand is highest in:
β India
Large nonwoven and meltblown manufacturing growth after COVID.
β Turkey
Strong textile and filtration industry.
β Vietnam
Rapid factory expansion for PP spunbond and PET fiber production.
β China
Still the worldβs largest nonwoven supplier.
β Middle East
Growing interest due to polymer industries in UAE and Saudi Arabia.
