Rainbow Mask 🌈 with the new Antibacterial Poplin

The masks for children and not so children can be fun and original. And that is why we have created this tutorial to make the most colorful and happy mask. In Katia, we have incorporated in these last days to our tissue catalog a new antibacterial poplin with biocide and waterproof treatment to make reusable “homemade” masks. In white and 7 solid colors. Combining these colors we have made this beautiful mask inspired by the rainbow that has accompanied us so much these days.

New Antibacterial Poplin


New Antibacterial Poplin Tecnosani White is an antibacterial 100% organic cotton fabric with the GOTS certification. It is suitable for sewing reusable face masks thanks to the biocide treatment which neutralizes bacteria and the waterproof finish that repels the penetration of saliva droplets. In addition to it being certified, this white antibacterial poplin meets the new UNE-0065 standard and is equivalent to the FFTP-2 standard. Follow our step by step videos showing how to make children’s and adult water-resistant face masks with a TNT filter, medical hats, gloves, and gowns.

Washing Recommendations:

  • Wash using a neutral detergent.

  • After washing, dry iron (without steam) at a temperature of 120º/140º for 10 to 15 seconds.
