Built for structures that are open or seen from both faces.\u003c\/p\u003e\n\u003cp\u003eFilm core is the reason this one stays thin. Where the earlier double-side build uses a textile backing for abrasion resistance, this one keeps a film core so the yarn stays fine enough for knitting and braiding without stiffening the structure it is worked into. Different job, different carry layer.\u003c\/p\u003e\n\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCode:\u003c\/strong\u003e RS-F-YR-02\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReflective face:\u003c\/strong\u003e Double side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore:\u003c\/strong\u003e PET film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaytime colour:\u003c\/strong\u003e Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReflective coefficient:\u003c\/strong\u003e \u0026gt;250 cd\/(lx·m²)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth:\u003c\/strong\u003e ≥0.5 mm, made to order\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Woven, braided or knit into fabric or trim\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhere double side changes what is possible\u003c\/h2\u003e\n\u003cp\u003eOn an open knit the strand is visible from both faces, and a single-side yarn loses its reflective face wherever the twist turns inward — the result is a reflective line that appears and disappears down the garment. A double-side build keeps it continuous, which is what makes reflective knits and braided cord workable at all rather than a pattern of bright and dead sections.\u003c\/p\u003e\n\n\u003ch2\u003eTypical use\u003c\/h2\u003e\n\u003cp\u003eOpen knits, braided cord, visible trim and structures where both faces of the yarn are exposed.\u003c\/p\u003e\n\u003cp\u003eIt is also used in knitting where the yarn passes through the machine repeatedly and a stiff build would not feed cleanly.\u003c\/p\u003e\n\n\u003ch2\u003eWhat to confirm before ordering\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructure:\u003c\/strong\u003e open knit, braid or two-face trim — that is what justifies the double side.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinished diameter:\u003c\/strong\u003e made to order from ≥0.5 mm; give the yarn or cord size.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasion:\u003c\/strong\u003e a film core is thinner but less forgiving than a textile-backed build — state if the yarn rubs against hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoefficient:\u003c\/strong\u003e stated at \u0026gt;250 cd\/(lx·m²); confirm against your target.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDaytime colour:\u003c\/strong\u003e grey as standard.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompliance note\u003c\/h2\u003e\n\u003cp\u003eA narrow-format element like this is a design component, not a retroreflective material in its own right. Reflectance is measured on a flat surface, and a yarn presents a curved and interrupted face, so it is not specified against the 330 cd\/(lx·m²) floor on its own.\u003c\/p\u003e\n\u003cp\u003eIt is normally used alongside a compliant panel rather than instead of one.
