PFAS-free waterproof breathable systems represent one of the most important shifts in performance textiles. But with that shift comes a critical and often overlooked reality:

The way we clean these materials has not kept pace with how they now fail.

A New Failure Mode: Contamination, Not Construction

Historically, PFAS chemistries provided more than water repellency.
They also delivered resistance to oils and complex contamination.

With their removal, performance systems are now exposed to a different set of challenges driven by real use:

• sustained sweat during climbing, ski touring, and running
• sebum (body oils) from continuous contact with skin
• sunscreen-we all need it! under high UV conditions and altitude
• biological contamination, including blood from abrasion or impact- the sudden dismount

These are not lifestyle, household stains that common detergents and even most ‘performance’ laundry care target.

The cleaning care needed is specific to address challenging high-load contamination specific to performance athletes, first responders and clinical care garments.

How Contamination Degrades Performance

These types of contaminants are not passive.

They are chemically active:

• Lipids (oils) adhere strongly to hydrophobic surfaces
• Proteins bond and denature within fibre structures
• Mixed residues form conditioning layers that disrupt DWR treatments causing wet out and that clammy feel in wear.

Over time, this leads to:

• degradation of DWR performance
• reduced moisture vapour transport- less breathable
• early onset wet-out and clamminess
• stress on tapes, coatings, and laminations- oils and residue make it difficult for repairs to bond, organic materials oxidize, causing laminations and barriers to fail.
• persistent odour – bacteria colonization

The system doesn’t fail all at once — it degrades progressively due to residual contamination and bacteria that colonizes within the textile weave, odour becomes persistent, garments no longer perform and are retired prematurely.

Why Traditional Cleaning Falls Short

Most detergents are optimized for:

• intermittent household use
• household and lifestyle contaminants (food, dirt, lipstick coffee)- Not the same as technical performance wear and tear.
• heat-driven and aggressive surfactant cleaning These systems rely on:
• hot water temperature to help melt and break down oils
• harsh chemicals, antimicrobials and biocides to mitigate odour persistence and bacterial colonization

In performance textiles, this approach creates conflict:

• heat can stress fibres, laminates, and coatings
• surfactant-driven cleaning does not fully break down protein + lipid systems (sunscreen, sweat, blood, body oils)
• residual contamination remains and re-binds allowing bacteria to colonize and become persistent and potentially mutate.

The result is incomplete cleaning and continued accumulation.

Why Temperature Matters:

Traditional detergents depend on temperature for effectiveness.

• oils require heat to become mobile
• surfactant efficiency increases with temperature

However:

• textile systems degrade under repeated heat exposure
• adhesives and laminates are sensitive
• yarn structure and membrane function are impacted

The Shift: From Temperature-Driven to Precision Cleaning

Biozyme Advantage cleaning care targets contamination at the molecular level without relying on heat

This is where enzymes become foundational, not optional.

Why enzymes are the right choice for technical care — and why they must be curated

Enzymes are not general cleaners.
They are specific biochemical tools:

Proteases break down protein-based contamination

• sweat
• blood
• organic residues

Lipases break down lipids

• sebum
• sunscreen
• skin-derived oils

Biozyme uses these and additional carefully selected enzymes to disrupt bacteria bio films and mitigate persistent odour and degradation.

These enzymes do not break down or weaken waterproof breathable barriers or laminations

What they do is – convert contamination into water-soluble fragments that can be effectively removed during rinsing

• enzymes break contamination down within the textile structure, rather than just lifting surface stains
• they operate effectively at lower temperatures (20–30°C)- no thermal stress, studies show that effective cool water cleaning results in less micro plastic shedding.Ocean Wise Study

Why “Any Enzyme” Is Not Enough

This is where most systems fail.

Effective enzyme cleaning requires:

1. Targeted Selection

Different enzymes are required for different contamination types.
A general blend is rarely sufficient for performance gear. The formulation needs to be designed for performance textiles, cooler temperatures and work in conjunction with the specific enzyme blend.

Enzymes must remain active in:

• the detergent formulation
• the wash environment
• the temperature range used

3. Formulation Alignment

They must be compatible with:

• surfactants
• water chemistry
• textile structure

If not: The system defaults back to heat + chemistry — and fouling/contamination accumulation with performance failure continues.

Why Cool Water Is Essential

When cleaning is aligned with enzyme performance:

• washing at 20–30°C preserves enzyme activity
• reduces thermal stress on fabric
• protects laminates, coatings, and adhesives
• limits fibre degradation and micro-structural damage

System-Level Benefits

When contamination is managed properly:

• moisture vapour transport is preserved
• DWR performance is maintained longer
• wet-out is delayed
• textiles retain comfort and thermal regulation
• lifespan of garments is extended

At the same time:

• energy use is reduced (less heating required)
• wash intensity can be lowered
• overall lifecycle impact is improved

A System Problem, Not a Single Step

The key shift is this: Performance retention is not just a materials issue — it is a care system issue.

Materials, contamination, and cleaning form a connected system:

• how the garment is used
• how contamination accumulates
• how it is removed

Bottom Line

PFAS-free waterproof breathable systems demand a new approach.

Not:

• hotter washes
• stronger chemistry
