Bonded onto PET base yarn, high‑refractive‑index glass micro‑beads deliver high retro‑reflective brightness and excellent nighttime visibility for shoe uppers. Soft yarn texture brings superior knittability and compatibility with fly‑knit circular knitting machines for 3D integrated upper weaving. Firmly adhered glass micro‑beads grant great washing and rubbing resistance so beads hardly fall off during shoemaking processing and end‑user wear. Satisfactory tensile strength prevents breakage under high‑speed knitting and minimizes production‑line downtime caused by yarn breakage. Stable physical properties and low shrinkage keep consistent reflective performance after knitting and post‑treatment. 

High‑visibility silver is the main stock option, and custom‑color reflective yarn is available for bulk orders. Large‑size industrial cones cut frequent spool‑changing work and boost continuous productivity in fly‑knit workshops. Optimized surface friction generates little flying lint to fit high‑speed textile equipment. As special functional knitting yarn for shoemaking fly‑knit workshops, it realizes integrated upper knitting for fly‑knit sneakers, running shoes and safety protective shoes, and creates decorative reflective stitching on shoe tongues, collars and straps. It also supports knitting for safety warning fabrics, sportswear and warning ribbons, weaving of reflective decorative fabrics and fashion accessories, as well as functional shoe sample development and prototype verification in sample‑making workshops.

Choose proper yarn denier according to fly‑knit fabric density: higher denier delivers striking reflective effect while lower denier offers subtle decoration. Adjust knitting‑machine tension reasonably; excessive tension will trigger glass‑bead shedding and yarn fracture. Prevent sharp‑edge friction during threading to safeguard the reflective bead surface. Avoid long‑term heavy mechanical scrubbing on finished fabrics to prolong reflective service life, and store unused cones sealed away from dust contamination. 

Eco‑friendly adhesive bonding is applied for glass‑bead coating with low‑VOC output to meet footwear environmental standards. Export cartons use recycled corrugated cardboard with water‑based ink printing, and single‑cone PE bags are recyclable. Reliable yarn quality reduces fly‑knit‑factory downtime and raw‑material waste from yarn breakage. Batch traceability is available and material test reports can be provided for overseas audits, alongside standardized operator labor protection to fulfill fair‑trade commitments. 

Optimized for direct use on fly‑knit circular machines, its retro‑reflective effect originates from surface high‑refractive‑index glass micro‑beads. Special bonding resists bead loss under normal washing and wearing; stocked deniers cover 150D, 200D, 300D, custom colors are offered for mass orders, and it is widely applied for night‑visibility decorative weaving on running‑shoe, safety‑shoe and fly‑knit‑casual‑shoe uppers.
