Revestimiento hidrofóbico para un tejido natural y compostable sin efectos en la compostabilidad


Demanda Tecnológica
Una empresa suiza ha lanzado su primera línea de ropa compostable (camisetas, pantalones y camisas). Las directrices para diseñar y fabricar ropa compostable son muy estrictas. Como consecuencia, el desarrollo de productos y el proceso de producción deja pocas o ninguna alternativa a determinadas características, como la impermeabilidad. La empresa busca socios que dispongan de tecnologías o know-how sobre revestimientos impermeables respetando sus criterios. El objetivo es establecer acuerdos de cooperación técnica, comercial y en materia de investigación.


Hydrophobic coating onto a natural and compostable fabric, without effects on compostability
A Swiss company has launched its first compostable clothing line. In order to achieve compostability for a piece of clothing, the guidelines for design and production are very strict. As a consequence of this the product development and production process leaves little to no alternatives for features like water repellency. The company is looking for partners who have the know-how for this kind of coating respecting their criteria. Commercial, technical or research agreements could be possible.
A Swiss company recently launched its first compostable clothing line with t-shirts, pants and shirts. In order to achieve compostability for a piece of clothing, the guidelines for design and production had and have to be very strict. This consequence during the whole product development and production process leaves little to no alternatives for certain features, such as water repellency.
They are now looking for know-how or technologies to achieve water repellency by means of a hydrophobic coating. The technology or know-how to apply should not compromise on the compostability of the clothes.
The existing clothing line has following characteristics:

Grown in Europe
The fabric is made from bast and modal fibres grown in Europe. Producing these native fibres protects the soil and requires much less water than cotton which is easier to process.

Other fibres fitting the same criteria (low footprint, European, biodegradable) would be possible.

Short transport routes
Compared to common textiles, the path from fibre to product is a short trip. The various production steps for the fabric take place at a distance of maximum 2´500 kilometers (1´600 miles) from Zurich.

Not toxic
While flax and hemp cultivation requires almost no pesticides, they also use as few chemicals as possible when further processing bast fibres. The company avoids bleaching altogether. This means that the fabric may also be recommended for babies and infants without any restrictions. This is the conclusion reached by Oeko-Tex® Standard 100 (product class I), an independent control and certification system.

Factory proof
Fabrics and garments have to be long-lasting and sturdy. The Swiss company uses it as workwear in the factory and also at the bar after work. The employees subjected all fabrics and products to strict testing, also taking style into account.

For the compost
The fabric satisfies the toughest factory requirements and yet is 100 % biodegradable in compost within just a few months.

Background of the company
The company is design driven and a pioneer in its area. Several products of their other product line are exposed in well-known museum collections. Products can be purchased world-wide.

The company is looking for partners or research partners who have either the know-how to achieve water-repellent properties of clothes or are willing to develop it together with the company respectively with the fabric producing company.
Every effect a solution has on the water resistance of a fabric is interesting for the Swiss company.
The company believes that the solution could come from the textile sector but more likely from other industries like e.g. the furniture industry.

Following cooperation types might be considered:

- Commercial agreement with technical assistance: with a partner that offers the suitable solution
- Technical cooperation agreement: with a partner who has a solution which has to be adapted to the requirements of the Swiss company
- Research cooperation agreement: with a research partner to develop the solution as no existing solution is available
Technical Specification or Expertise Sought:
Beside the characteristics of the existing clothing line the following criteria has to be fulfilled:

- The end result has to dissolve completely in an ordinary compost within a few months. = Cradle to Cradle approach
- If possible, the solution should be vegan
- The solution has to be applicable on natural fabric made of flax, hemp and modal
- It should be possible that the coating can be applied in Europe

Regarding the water repellency
- Breathability of the fabric: optional
- The solution might be applied during the finishing process of the fabric or might be renewed during some time of use

Partner sought

Type and Role of Partner Sought:
The specific area of activity of the partner:
For all the three cooperation types the sought partner should be active in the coating of textiles or in the water repellence of materials and meet the above mentioned criteria (in research stage or further developed).

The tasks to be performed by the partner sought:
Commercial agreement: Provide the suitable solution.

Technical cooperation agreement: Adapt an existing solution to the required specifications of the Swiss company.

Research cooperation agreement: Develop the suitable solution together with the Swiss company.
