Coatings: Biopolymers from Bacteria Protect Technical Textiles
Textiles for technical applications often derive their special function via the application of coatings. This way, textiles become, for example, wind and waterproof or more resistant to abrasion. Usually, petroleum-based substances such as polyacrylates or polyurethanes are used. However, these consume exhaustible resources, and the materials can end up in the environment if handled improperly. …
Conductive Textiles
Development of Electrically Conductive Polyester Yarn by Surface Modification for Smart and Technical Textiles Until textiles take their place in our lives, it involves many complex and long processes such as fiber and fabric production, finishing processes, sales and marketing (Figure 1). Textile structures, which were first developed to meet the dressing needs of people, …
Coatings & treatments for PPE and protective apparel
Coatings and treatments at the fiber level are primarily utilized as a process aid. These ingredients can be used to heat stabilize the fiber while it is spun and stretched. They can also make the fibers easier to convert into the final fabric, and they can even be washed away during the process. Meanwhile, coatings, …
Student Spotlight: Reusable textiles for liquid and virus repellency
Anthony John Galante is pursuing a Ph.D. in Industrial Engineering at the University of Pittsburgh, where he is conducting research on microbe repellent surfaces at the Lab for Advanced Materials in Pittsburgh (LAMP). His research focuses on the application of surfaces with different functionalities such as self-cleaning, stain-resistance, bacteria-repellency and virus repellency. Galante’s interest in …
New biocide for coating fibers to create antimicrobial textiles
A Finnish company has developed an antimicrobial technology designed to eradicate highly resistant and dangerous pathogens, including the top five on the World Health Organization’s list of dangerous bacteria.
The new Nolla technology is also applicable for fiber coating, explained Jyri Nieminen, chief executive officer of Nolla Antimicrobial.
The technology is based on ionic silver, which is the most potent antimicrobial form of silver. An intelligent polymer carrier is used to preserve and deliver the silver ions.
