Electrospinning. Advantages & Applications

Electrospinning is an excellent candidate process for producing nonwoven mats for wound dressings, tissue engineering and drug delivery, since the resulting electrospun materials possess a high surface-to-volume ratio, an interconnected three-dimensional porous network, the small diameter filaments or the easily changing fibers’ size, among other properties.

Textile fibers have been used throughout the history of mankind for different purposes. When at the beginning animal fibers and later on with on-going technology improvement also plant-based fibers (e.g. cotton, flax, hemp) and even mineral fibers (mineral wool) were used widely, with the rise of chemical industry, man-made fibers (made of natural or synthetic polymers) became more and more important. Electrospinning is one of many processes to produce fibers but is enabling POLYBIOSKIN’s bio-based nano-fiber production with advanced properties at a new level.

Extrusion Process and Calendering

Biodegradable polymers’ use in applications like packaging and skin contact items, often used in sanitary and personal care products is currently increasing. 

  • Poly(lactic acid) (PLA) is the most used renewable and biodegradable polymer, due to its high tensile strength, good heat stability during processing, excellent biocompatibility and excellent gloss and transparency.

Most plastics, more precisely: Thermoplastic materials can be shaped into a wide variety of products, such as molded parts, extruded sections, films and sheets as well as fibers for textiles. To shape a thermoplastic polymer, it must be heated so that it softens to the consistency of a liquid (this form is called polymer melt).

The following presentation will give an overview on important industrial processes, needed for products made of plastics. This is the basis for all POLYBIOSKIN products.

Mechanical Tests for Polymers

Knowledge of the properties of materials is essential for several purposes:

Design, specification, quality control, failure analysis and for understanding the structure and behaviour of new materials.

Mechanical properties express the ability of a material to resist actions caused by external forces tending to deform it.

Testing indicates qualitatively and quantitatively how the polymer will behave under certain real-life conditions.

Skin Compatibility

Biocompatibility is defined in terms of BioMaterial Performance or success at a specific task and has to be uniquely defined for each application following toxic, microbiologic, mechanical and cell-biomaterial interaction factors.

Skin compatibility means biocompatibility in general:

When using modified bio-based products, it is important to understand how the human skin works and how (bio)materials in skin care products can support it.
