NEST-TEX technology platform

How the membrane works

One core material, adapted for many industries. Electrospinning turns a polymer solution into continuous nanofibres; NEST-TEX controls the process to build a fine, porous fibre network instead of a solid film.

NEST-TEX membrane

Electrospun nanofibres about 45 nm in diameter form pores smaller than 50 nm. The standard membrane has a water column of 10 500 mm; porosity and water column can be set to your specification.

Beyond textileResearch & development

What the technology can enable next

Battery separators, air filtration and wound care show the broader potential of the NEST-TEX platform. They are development areas open to testing, research partnerships and future commercialisation, not products for sale today.

02 / Battery technologyR&D

Separator material for lithium-ion batteries

Li-ion cell · schematic Cathode Separator Anode Li⁺ ions pass through the pores

Inside a lithium-ion cell, the separator keeps anode and cathode apart while letting ions pass. The characteristics and structure of the NEST-TEX material create opportunities for further research, testing and development in this role.

This is a technology development area. NEST-TEX invites battery manufacturers, research institutions, engineering companies and development partners to discuss cooperation.

03 / Air filtrationR&D

Filtration materials for cleaner air

Air in Filtered air out Nanofibre filter medium · concept

NEST-TEX sees two areas for developing filtration materials from its membrane technology: professional and controlled environments such as hospitals and operating rooms, and everyday indoor air for people living in large cities with significant air pollution and particulate contamination.

  • Air purification systems
  • Indoor air filtration
  • Professional filtration systems
  • Urban environments
  • Specialised controlled environments

These are application and development opportunities; filtration performance and certifications for specific products are to be established with partners.

04 / Wound careFuture R&D

ArtSkin: breathable structures for wound care

Breathable covering · concept Skin Protection with controlled exchange

ArtSkin (from Artificial Skin) is the NEST-TEX technology line for wound and burn care, based on chitosan nanofibre fabrics. Its porous, breathable structure creates an opportunity to investigate coverings where protection and controlled exchange with the environment may be desirable.

  • Breathable coverings for wounds and burns
  • Patches
  • Advanced dressing structures
  • Development collaborations

Wound care is a future research and development application of the NEST-TEX platform. NEST-TEX does not offer medical products and makes no therapeutic claims.

About NEST-TEX

From advanced material to real-world products

A European material-technology company, beginning commercialisation through the textile industry.

NEST-TEX d.o.o. is a material-technology company from Ljubljana, Slovenia, co-founded by director Peter Emri and Acad. Prof. Dr. Igor Emri, the inventor of the technology. We develop electrospun, nano-structured membranes and bring them to market first through textiles.

Our approach is rooted in material science: understanding how polymer structure, fibre formation and mechanics interact, and using that knowledge to control the fibre network a membrane is made of.

We work as a lean core team with a network of research laboratories, experts and industrial partners. Our ambition is to build an interdisciplinary platform around one membrane technology: textiles today, and battery, filtration and wound-care applications through research and partnerships.

Material science first

Every application starts from the structure of the fibre network.

One platform, many industries

A single core technology, adapted for each application.

Clear about readiness

What we sell today is kept separate from what the technology may enable.

Built with partners

Laboratories, manufacturers and developers across all four fields.

4. NEST-TEX material (business customers)

5. Made-to-measure jackets

Fittings take place on working days by arrangement, at Cesta Dolomitskega odreda 10c, Ljubljana, or at an address agreed in advance. The measurements are taken by NEST-TEX. After measuring, we send a pro-forma invoice based on the chosen model, colour, extra pockets, materials and size; prices for consumers include VAT. Production starts once payment has been made as stated in the pro-forma invoice.

6. Covers and other custom products

Covers and tarpaulins are made to the dimensions you provide or that we measure. You are responsible for the accuracy of dimensions you provide. The indicative price is €50/m² excluding VAT and the quantity of a limited edition is agreed with each order; the binding price is stated in the quotation and the order is paid 100% in advance.

7. Delivery

We deliver worldwide. Delivery costs are paid by the customer and are stated in the offer or pro-forma invoice, together with the delivery method. Delivery dates vary; the estimated delivery date is confirmed in the offer or pro-forma invoice and is not a fixed deadline unless expressly agreed in writing. For deliveries outside the European Union, any customs duties and import charges are paid by the customer.

8. Right of withdrawal for consumers

Where a consumer concludes a distance or off-premises contract, the statutory 14-day right of withdrawal generally applies. It does not apply to goods made to the consumer’s specifications or clearly personalised, which includes made-to-measure jackets and custom covers.

9. Conformity and complaints

Consumers have the rights provided by Slovenian consumer protection legislation if a product does not conform to the contract. Please report any issue to info@nest-tex.com with a description and photos. Business customers must inspect deliveries on receipt and report visible defects in writing without delay, at the latest within 8 days of delivery.

11. Intellectual property

The website content, the NEST-TEX and ArtSkin names and the underlying technology, including pending patent applications, are protected. Buying material or products does not grant any right to reproduce the technology.

12. Force majeure

Neither party is liable for delays or failure to perform caused by circumstances beyond its reasonable control.

13. Personal data

We process personal data as described in our Privacy Policy.

14. Law and disputes

These terms are governed by the law of the Republic of Slovenia. We aim to settle complaints amicably. For business customers, the competent court in Ljubljana has jurisdiction.
