The microfiber ultrafine silk – MicronSilk: the natural future of intelligent comfort

The technical characteristics of ultrafine silk concerning its volume, diameter, and fiber thickness are well known. Silk is in all respects a natural microfiber capable of generating an ultrafine yarn, an ultrafine fabric, and an ultrafine padding thanks to its regular and cohesive structure of thermoregulating silk

The study of the molecular structures of silk and the knowledge of production techniques have allowed Cosetex to select specific ultrafine silk productions capable of consistently achieving absolute fineness levels, increasingly thinner and lighter fibers, and more cohesive and soft structures.
This natural silk microfiber represents a balance between science and comfort, combining the properties of traditional silk with the precision of technical materials microfiber ultrafine silk.
Tested by the laboratory CELLS of the Politecnico di Milano, Department of Electronics, Information and Bioengineering, the filaments of our ultrafine silk fibers have consistently demonstrated characteristics in line with the most technical microfibers, while avoiding the major disadvantages of synthetic textile microfibers:

• Ultrafine mulberry silk fibers with fiber diagrams ranging from 8 to 11 microns
• Ultrafine wild tussah silk fibers with fiber diagrams ranging from 6 to 12 microns
• Stability within cohesive combed ultrafine silk noil

These characteristics make MicronSilk, ultrafine silk microfiber a high-performance natural silk, ideal for intelligent textiles and sustainable comfort of thermoregulating silk.

The tangible results are those of a fiber that is a new example of material precision, where every micrometric reduction in fineness increases the active surface of the silk:

• Lightness and sheen: Microsilk offers an extremely smooth and reflective surface, with unique light refractions.
• Softness and suppleness: the microfibers adapt to the body’s morphology with unparalleled smoothness on the skin.
• Intelligent thermoregulation: warmth in winter, coolness in summer, a constant adaptive thermoregulator that balances temperature and breathability.
• Balanced micro-breathability: MicronSilk fabric balances air, water vapor, and humidity levels by regulating perspiration.
• Moisture control: the increased density of microfibers absorbs and releases vapor in a balanced manner, eliminating the sensation of dampness and regulating temperature.
• Absence of friction: the perfectly smooth external surface of numerous microfibers minimizes mechanical stress on skin and hair.
• Naturally hypoallergenic and antibacterial: amorphous zones within the individual fibrils and the inherent qualities of silk prevent the accumulation of mites and allergens without the use of chemical treatments.

MicronSilk is true technological microfibre ultrafine silk, a natural thermoregulating micro-silk that looks to tradition while projecting into the future, ideal for high-end garments, high-performance padding and fillings, ultra-soft fabrics, innovative yarns, and high-performance technical apparel
