Resumen:
Una empresa alemana especializada en fibras especiales de viscosa busca socios que distribuyan materiales porosos, preferiblemente partículas, para producir fibras de viscosa celulósica con mejores propiedades mecánicas y químicas para su aplicación en tejidos funcionales para ropa, tejidos técnicos non woven, productos de higiene y papeles especiales. Los materiales celulósicos se basan en materias primas renovables y son totalmente biodegradables. Las propiedades intrínsecas de los materiales celulósicos son el buen control de humedad y la alta capacidad de absorción de agua, alrededor del 80%. En comparación con la fibra sintética, las fibras celulósicas tienen un alto peso específico de alrededor de 1,5 g/cm³. La empresa está interesada en establecer acuerdos de cooperación técnica.

Partners sought for the development of high-performance cellulosic fibre materials
Summary:
A German company specialised in viscose specialty fibres is looking for partners who distribute suitable porous materials, preferably particles, to produce cellulosic viscose fibres with superior mechanical and chemical properties for applications in functional apparel textiles, technical nonwovens, hygiene products and specialty papers. Technical cooperation agreements are sought.
Description:
The German company is a leading specialty manufacturer of viscose fibres and provides customers worldwide. It has a strong focus on innovative products and novel technologies, where viscose fibres can play an important role.

Cellulosic materials are based on renewable raw materials and are completely biodegradable. Due to their structural properties, they are very versatile and are therefore applied in numerous applications ranging from fashion, hygiene and medical products to nonwoven fabrics. Intrinsic properties of cellulosic materials are a good moisture management and a high water absorption capacity of about 80%.

Compared to synthetic fibre materials, cellulosic fibres have a high specific weight of about 1,5 g/cm³ (grams per cubic centimetre). There are additional textile, technical and hygiene applications for cellulosic fibres with a lower specific weight of about 1,1 g/cm³. Currently, the company is seeking partners to jointly develop cellulosic viscose fibres with a lower specific weight. The fibres should retain the physical and chemical properties needed to process them into textile and nonwoven structures.

An approach towards an improvement of the cellulosic viscose fibres could be the production of composite materials by incorporating porous, at best biodegradable particles into the cellulose matrix during the production process.

Technical cooperation agreements are sought to produce composite viscose fibre materials with superior mechanical and chemical properties and to test their market potential.



Technical Specification or Expertise Sought:
Technical requirements regarding the composite material to be developed:

i) Particle diameters of D50 = 2 µm, D90 = 5 µm und D100 = 10 µm are required (e.g. D50 is the diameter at which 50% of the sample´s mass is comprised of particles with a diameter less than this value).

ii) An additive content of < 10 weight % should reduce the density of the fibre materials from 1,5 g/cm³ (pristine cellulose) to about 1,1 g/cm³.

iii) Ideally, the sought porous materials are bio-based and/or biodegradable.

iv) Chemical resistance of the particles in an aqueous medium at a pH of 14 over several minutes. The dispersed particles must not agglomerate or decompose.

Partner sought

Type and Role of Partner Sought:
In particular, cooperation partners are sought who distribute suitable porous materials, preferably particles, and who are willing to jointly produce marketable composite materials. Test batches can be produced in the facilities of the German company. The potential partner should possess expert skills in particle technologies. A knowledge in fibre technologies is a plus.

Technical cooperation agreements are sought to produce composite viscose fibre materials with superior mechanical and chemical properties and to test their market potential.
