Materials for advanced textiles: Nanocomposite biocomponent and antimicrobial fiber

Hilos
Nowadays, a number of social, technological and health challenges are pushing the 
industry and academy to develop solutions to improve the life´s quality of human beings.
 
For this reason, the Research Centerfor Applied Chemistry (CIQA) has developed patented nanotechnology based on polymers and nanoparticles to help a wide range of industries, including technical textiles with application in the healthcare sector.

Hospital acquired infections are a current problem throughout the whole world. It is estimated that 5 to 10% of patients hospitalized in North America and Europe show hospital acquired infections, while in Latin America, Asia and Sub-Saharan Africa this number rises to 40%. According to the World Health Organization, every year more than 1.4 million people in the world acquire infections in hospitals.

Hospital acquired infections extend the patient's stay in the hospital, enhancing the possibility of a long-term disability, while generate a greater resistance of the bacteria to the medications, increasing the medical costs for the patient, the family and the health sector, and also cause unexpected deaths.

In the interest of provide a solution to minimize nosocomial infections, CIQA developed high-performance nano concentrates used to produce bicomponent fibers to be used I the manufacturing of advanced textiles. Thus, providing a technological option to manufacturers of hospital clothing and blankets.

How does it work?
An antimicrobial particle, which has the property of inhibiting the spread of fungi and bacteria, is incorporated into a polymer through melt extrusion. During this process, in its liquid state, the mixture goes through a process in which the materials are more efficiently dispersed, getting as a result pellets of optimized nanoconcentrates.

These pellets are introduced with another polymer in a melt spinning machine that will form bicomponent fibers. The research team has such control of the process, that is able to determine where to place the nanoconcentrated inside each fiber to use efficiently thematerials and to reduce the costs. These fibers will be subsequently used for yarn manufacturing or for non-woven fabric production.

This type of antimicrobial fabric has a huge advantage against fabrics already on the market, because most of them lose their antimicrobial features in each wash because they are surface coated. With the manufacturing process developed at the CIQA, the material can be placed within the fiber, which extends its effectiveness during the lifetime of the garment. Besides, no toxic additives are added.

The processes to get a nanoconcentrate optimized to be used in the manufacture of antimicrobial textile fibers were developed and patented by a researchers team in the Research Center for Applied Chemistry, located in northwest of Mexico in the city of Saltillo, Coahuila. The working team have 3 patents granted and more than 30 patent applications.
