Water repellent treatment

To meet requirements related to function and care, the outermost fabric layer used in outdoor clothing generally has a water repellent treatment on the outside and a membrane on the inside. The Sympatex membrane ensures that functional clothing is waterproof. Water repellent treatments also ensure that the textile has durable water repellent properties. A DWR (durable water repellent) treatment is an extremely thin coating of the individual fibres of the fabric which renders possible that water simply forms beads and rolls off. This treatment prevents or delays the ingress of water into the fabric. As a result the garment does not absorb water, you do not start to feel clammy and the good breathability of the garment is retained.

DWR technologies and their performance can generally be divided into two groups:

  • Fluorocarbon-based DWR (PFC)
  • Fluorocarbon-free DWR

Fluorocarbon-based DWR

  • PFC-based
  • Properties: water; oil; dirt repellent
  • High performance for classic outdoor activities
  • Might contain or degrade into PFOA:
    hazardous to the environment and human beings

EXAMPLES OF POSSIBLE SOURCES OF PFC

  • Production of FC-based DWR
    • For example residues of n:2 FTOH caused by incomplete transformation in the production process
  • Fluoropolymer production
    • For example PFOA used as an additive in the PTFE production process
  • Volatile PFC
    • For example release of n:2 FTOH from DWR by enzymatic chain cleavage

Fluorocarbon-based DWR

  • PFC-based
  • Shorter fluorinated chain
  • No degradation into PFOA
  • Properties: water; oil; dirt repellent
  • High performance for classic outdoor activities
  • Environmentally friendlier alternative: less bioaccumulation in human body

Fluorocarbon-free DWR

  • PFC-free
  • Properties: highly water repellent; excellent wearer comfort
  • High performance for classic outdoor activities
  • No oil and dirt repellency
  • Ecological alternative

POLYGIENE® ODOR CONTROL TECHNOLOGY

HOW DOES IT WORK?

THE SUBSTANCE

Nano particle-free solution based on natural silver salt from recycled silver. Applied to the the inner side of the laminate.

The effect

The Sympatex membrane is bacteria proof. In addition Polygiene® neutralizes odor by preventing the growth of odor-causing bacteria in the inner Sympatex fabric.

The use

Applicable for 3-layer laminates and liners.

THE BENEFITS

  • Extended life of garment
  • Longer wearing period – less washing – less wear and tear
  • Lower environmental impact
  • Odor free effect guaranteed for the lifetime of the product
  • Longer life of fibres due to freedom from bacterial growth
  • bluesign® approved
  • Oeko-Tex® Standard 100 certified
  • Skin-friendly. No interference with the skin‘s natural bacterial flora
  • Does not affect recyclability or breathability of laminate
  • Fresh all-day confidence
