  • Publication number: 20200146417
    Abstract: There is disclosed a hair fastener. The hair fastener is in the form of a loop for securing a log of hair within the loop. The hair fastener has an inner elastic core and an outer fabric enveloping the inner elastic core, wherein the elastic core is made of a band with a width of 2 to 6 mm and a thickness of 1 to 3 mm, and made of thermoplastic elastomer (TPE). The hair fastener is adapted to assume a first, default, configuration in which an opening defined and surrounded by the loop has a first area and a second, fully expanded, configuration in which the opening defined and surrounded by the loop has a second area. Due to the physical configuration and material characteristics of the band, the band is elongateable up to 8.5 to 10 times of its original length thus enabling the first area of the loop to expand to the second area by a factor 72.3 to 100.
