LIBERAL LARK coats, tailor-made exclusively from natural materials (wool, cotton, silk, cashmere) of the highest quality, you can choose either without a membrane or with two types of membranes. The membrane is applied from the underside of the natural fabric. The upper side of the natural fabric is always treated with a special invisible oleophobic and hydrophobic transparent layer.
The nanofiber membrane
Unique structure of Nanomembrane
Thanks to a unique nanofibrous structure with the fibre diameter of less than 150 nm, on 1 cm2 the Nanomembrane nanofibrous membrane has 25% more pores than microporous membranes. This helps the Nanomembrane achieve unique attributes that no other membranes in the world can match.
Excellent permeability, breathability and durability
It is no secret that the Nanomembrane nanofibrous membrane is very similar to human skin, thanks to which Nanomembrane can flaunt with extremely high vapour permeability, i.e. the ability to remove body moisture from human skin to the external environment. Vapor permeability of the two layer laminate with nanofibrous membrane is from Ret 0,89. Moreover, the Nanomembrane nanofibrous membrane is 100% wind resistant and it boasts extreme hydrostatic resistance.
It does not release water, chemicals, nor viruses or bacteria
Not only is the Nanomembrane nanofibrous membrane highly hydrophobic with adequately high water column, but it is also highly oleophobic. The surface of the Nanomembrane nanofibrous membrane is coated with a thin layer of nanoparticles creating the so called “lotus effect”, which prevents the unique pores from soiling and subsequent deterioration of the excellent properties of the Nanomembrane nanofibrous membrane. Moreover, the same technology is used for the upper knitted and woven fabrics to which the Nanomembrane nanofibrous membrane is laminated, making it impossible for impurities as well as other materials to adhere to the surface of the fabric.
The non-porous membrane
The non-porous or hydrophilic membrane is made of very flexible PU. Moreover, unlike other non-porous membranes, it excels thanks to low basis weight. Thanks to this, we have achieved a high level of vapour permeability. Moreover, this membrane is typical of high level of wash resistance.
Upper oleophobic and hydrophobic resistance
Moreover, all natural fabrics have a hydrophobic finish using so called DWR treatment: Fluorocarbon type C6 and Fluorocarbon free so called hydrocarbon – PFC-free. Both finish types offer high level of hydrophobicity with similar extremely long service life. The fluorocarbon type C6 has an oleophobic finish a the PFC-free offer maximum possible level of environment protection.

How to care for fabrics
COTTON & MEMBRANE
- Fine washing at 30°C
- Spin-drying up to 800 rpm
- Laundry detergent intended for membrane clothing
- Do not use fabric softeners
- Iron the product after every washing. This will activate the nanoparticles repelling water, oil and other impurities
- You can use a clothes dryer instead of ironing
- It is recommended to wash two layer laminates separately
- Can be dry cleaned
WOOL, SILK & MEMBRANE
- Dry cleaning only
- Iron the product after every dry cleaning. This will activate the nanoparticles repelling water, oil and other impurities
