Textile desizing
Plasma breaks down or modifies sizing layers before washing. The aim is a shorter wet route, reduced chemical demand and reproducible absorbency without compromising fabric strength.

OUR SCOPE
Technology, equipment and process know-how in one system.
A successful plasma installation is more than a generator and an electrode. EPCOTEC develops the surface reaction together with web handling, atmosphere, exhaust, cleaning, spray application, thermal treatment, automation and the surrounding production process.
01
Process development & trials
Define the required surface function, select the plasma regime and establish a measurable treatment window.
02
Atmospheric plasma systems
Continuous treatment of roll goods and three-dimensional components without a vacuum chamber.
03
Low-pressure plasma systems
Uniform activation, cleaning and functionalization under precisely controlled gas and pressure conditions.
04
ROTOPLASMA line integration
Synchronize plasma exposure with web handling, spray application, drying, exhaust and line controls.
05
Desizing & surface activation
Remove or weaken size, increase wettability and prepare fibers for washing, dyeing, coating or bonding.
06
Industrial commissioning
Translate validated pilot parameters into electrodes, generators, safety systems and production recipes.
FROM LAB TO LINE
Plasma that fits the production line.
Development begins with the material and the required surface function. Laboratory trials identify whether activation, cleaning or functionalization is technically effective. The representative pilot then connects treatment intensity with exposure time, working width, speed, temperature, atmosphere and downstream operations.
Only after performance and repeatability are documented do we define the industrial configuration. This protects the project from scaling an isolated laboratory effect that cannot survive real web tension, contamination, production variation or continuous operation.
APPLICATION FIELDS
One surface technology, engineered around six different production outcomes.
02
Adhesion improvement
Controlled activation raises surface energy so coatings, laminates, printing inks and adhesive systems can wet and anchor more reliably on textile and polymer surfaces.
03
Hydrophilic & hydrophobic finishing
Plasma activation and low-add-on spray finishing can reduce liquor pickup and drying load. Process chemistry can be selected for wetting, moisture management or water-repellent behavior.
04
Dyeing & printing preparation
Surface activation improves wetting and chemical accessibility before dyeing or printing. EPCOTEC coordinates plasma dose, spray application, steaming, washing and drying as one route.
05
Technical textiles
Atmospheric and low-pressure systems support activation and functionalization of woven, knitted, nonwoven and composite structures for demanding technical applications.
06
Filtration & composite surfaces
Plasma can prepare filter media, membranes and reinforcement textiles for coating, bonding and functional layers while preserving the bulk properties of the substrate.
THE EPCOTEC PROJECT PRINCIPLE
Pilot first. Validate the complete process. Then scale up with measured evidence.
EPCOTEC does not treat the pilot as a small demonstration machine. It is the technical evidence base for the industrial plasma line. The pilot must reproduce the decisive physics and interfaces of production: electric field, electrode geometry, treatment gap, gas or air flow, surface dose, substrate speed, web tension, moisture, temperature, exhaust and downstream processing.
Every project therefore starts with a defined product target and ends with a documented industrial design basis. Samples, operating data and quality results are correlated before investment in the full working width and production capacity.
Define the surface target
We translate the required outcome—wettability, adhesion, desizing efficiency, coating pickup, durability or filtration performance—into measurable acceptance criteria.
Characterize the material
Fiber chemistry, construction, finish, contamination, moisture, thermal limits and line speed determine which plasma mechanism and handling concept are realistic.
Build the representative pilot
Electrode geometry, generator power, gas or atmosphere, treatment gap, exposure time, tension, exhaust and downstream steps are combined in a purpose-built pilot.
Validate the process window
A structured test matrix establishes quality, repeatability, operating limits, energy demand, safety requirements and the response to normal production variation.
Scale to the production line
Validated dose and transfer relationships become the basis for working width, number of treatment zones, electrical power, speed range, controls and interfaces.
Commission and optimize
EPCOTEC supports installation, recipe transfer, operator training, acceptance trials and ramp-up until the agreed product and process criteria are demonstrated.
What must be proven before scale-up
Surface performanceContact angle, wettability, adhesion, desizing result, coating pickup or customer-specific functional test.
Process stabilityRepeatability across material lots, start-up, steady running, production disturbances, cleaning and shutdown.
Industrial transferTreatment dose, line speed, working width, number of zones, power density, ventilation and thermal limits.
Safety & environmentHigh-voltage protection, ozone and exhaust management, interlocks, operator access and emissions concept.
EconomicsEnergy, gas, water, chemicals, drying demand, maintenance, consumables and realistic production cost.
