Recent experimental realisations in optics, fluids and nematic liquid crystals make it important to fully characterise these textures and to understand how their properties relate to the knot type. We characterise knotted nematics through an application of classical knot theory founded upon the Pontryagin-Thom construction for nematic textures and give explicit closed form constructions for knots possessing Milnor fibrations with general boundary conditions.
