Continuous Web Processing Oven for Resin Application in Textile Industry
Executive Summary
Epcon delivered a custom-engineered continuous web-processing line for textile fabric in which resin is applied and cured using a dedicated oven, paired with a high-efficiency airborne emission control system. The integrated setup ensures safe and compliant handling of solvent- and resin-based VOC emissions, while providing uniform resin curing, stable continuous throughput, and energy-efficient operation through optimized thermal and exhaust management. This project underscores Epcon’s capability to supply turnkey web-processing ovens with built-in air pollution control for textile and other continuous-web processing industries.
Project Overview
A textile-industry customer processing continuous fabric webs required a tailored process line to apply resin coatings (resin impregnation, adhesive/back-coating, or similar) to moving fabric web and then cure the resin uniformly along the web. Given the solvent or resin-based chemistry, the exhaust air would contain volatile organic compounds (VOCs) — needing reliable treatment. Epcon was contracted to design, fabricate, and commission a continuous web-processing oven + integrated VOC-control (oxidizer) system, ensuring both effective resin curing and compliant emissions abatement.
The Challenge
The project involved several serious technical and regulatory challenges:
- Resin application to continuous textile web often generates VOC-laden exhaust (from solvents or uncured resin constituents) when heated — necessitating effective emission control to meet air-quality and environmental standards.
- The curing oven had to provide uniform, repeatable heat and controlled thermal profiles over continuous web material — avoiding overheating, hotspots or uneven curing that could degrade fabric or resin properties.
- The system needed to support continuous throughput (running fabric web nonstop), meaning the exhaust-treatment unit must handle large, continuous airflow with fluctuating VOC loads.
- Energy efficiency was critical: continuous web curing and VOC destruction can consume large amounts of energy, so minimizing fuel/energy costs through heat recovery or efficient oxidizer design was desired.
- The solution had to be robust, industrial-grade, and capable of seamless integration into existing or planned production lines — including ducting, exhaust handling, and controls — with minimal maintenance and reliable performance.
Engineering Requirements
To meet the customer’s production, environmental, and economic goals, the system design needed to deliver:
- A continuous web-processing oven engineered for textile fabric with resin application — able to maintain uniform heating, stable airflow, and consistent resin cure along the moving web.
- A thermal oxidizer or equivalent VOC-abatement unit sized for continuous high-flow exhaust air and capable of treating solvent-/resin-based VOC emissions from the curing process.
- Reliable VOC destruction efficiency, sufficient for regulatory compliance (e.g., 99%+ VOC reduction where applicable) — to meet emission standards for textile/resin operations.
- Exhaust-air handling and ducting designed for high continuous airflow, safe transport of VOC-laden air, and stable operation under variable conditions (web speed, VOC load, ambient conditions).
- Optionally, heat recovery mechanisms where feasible (e.g., reclaim heat from oxidizer exhaust or oven exhaust) to preheat combustion/oxidation air or support process heating — reducing net energy consumption.
- Industrial-grade build quality plus automation and control systems to maintain constant process parameters, monitor emissions control performance, and ensure safe, stable operation even over long runs.
The Solution
Epcon designed and delivered a custom Continuous Web-Processing Oven + Integrated VOC-Control System for resin-applied textile processing, featuring:
- A conveyorized/roller-based continuous oven sized for web fabric, with carefully engineered airflow and heating distribution to deliver uniform resin curing across the full web width and length.
- A thermal oxidizer (or equivalent VOC abatement unit) integrated into the exhaust system to treat all VOC-laden air generated during the resin-curing process, ensuring emissions are destroyed prior to discharge. Thermal oxidizers (especially regenerative designs) are widely accepted in web-processing and coating industries due to their high destruction efficiency and heat-recovery potential.
- Exhaust ducting and ventilation engineered to handle large continuous airflow, safely transport solvent- or resin-laden exhaust to the oxidizer, and maintain stable combustion/oxidation conditions despite fluctuations in VOC concentration or web speed.
- (Where process permits) Heat-recovery provisions, enabling captured heat from oxidizer exhaust or oven flue to be recycled — for preheating combustion air or supplying part of the oven’s thermal demand — thereby reducing overall energy consumption and operating costs.
- Industrial-grade materials, controls, and automation to support continuous production conditions, solvent-rich exhaust streams, and long-term reliable operation.
- Full turnkey delivery: design, fabrication, controls integration, installation support, and commissioning — delivering a ready-to-run continuous resin-application and curing line with emissions control.

The Results
After installation and commissioning, the system delivered key benefits:
- Effective VOC abatement and emissions compliance — the oxidizer treats resin-curing exhaust air, ensuring regulatory compliance even during continuous web operations.
- Uniform, high-quality resin cure across continuous fabric web, with consistent material properties and minimized defects thanks to controlled oven conditions and stable thermal profile.
- Reliable continuous production throughput, supporting constant web feed rates without interruptions while maintaining emissions control and curing quality.
- Improved energy efficiency and reduced fuel/energy costs, particularly when heat-recovery is utilized to reuse exhaust heat and reduce net thermal demand.
- Simplified operations via turnkey delivery, reducing customer burden: the system is delivered fully engineered, installed, and ready to operate — minimizing risk and downtime.
- Enhanced sustainability and environmental performance, combining high-efficiency thermal processing with effective VOC destruction and optional energy reuse.
