Retroreflective yarn in action - for when you need to be seen.


Retro reflective technology can be obtained with the use of two types of raw materials:
  • glass beads
  • micro prisms

Our reflective yarns are manufactured with films having glass beads incorporated.

The role of the glass beads is to reflect the incoming light to its original light source. This means that the glass beads act as spherical lenses and return the incoming light to the light source when the reflective layer is set in its focus point.

The highest retro-reflective quality yarn available is made from 3M Scotchlite film. This yarn is available in many counts in both supported and unsupported forms.
  • RRC

  • Flash
    a very fine supported and unsupported retro-reflective yarn most suitable for weaving due to its relative high yield compared to other retro-reflecitve yarns. 

Programme of retroreflective flat yarn
3M Scotchlite types (No. 1 & No. 2) are not available any more due to production stop.

Suitable for knitting are the ones marked with "2x20". These are supplied on cones.
All the others (without the nylon support) are supplied on bobbins and are not suitable for knitting unless it is handknitting.

Yarn is not dyed and not suitable for dyeing.

Circular knitting, flat bed knitting or hosiery possible. However customer must be aware that these retro-reflective yarns are not easy to work. First of all they are heavy and secondly due to the glass beads they are quite abrasive (wear on needles)! Also finishing is not too easy: no dyeing - avoid alkali or acid treatments.
