Self-Locking Recycled Core Thread
Recycled Staple Spun Polyester Fiber & Recycled Polyester Filament
This is an eco-friendly core-spun sewing thread, manufactured with recycled raw materials derived from PET bottle flakes, designed to strengthen the fastening durability of garment buttons. With a unique self-locking structure, the thread forms a firm lock after heat activation by steam or conventional ironing, significantly boosting structural stability and button holding power.While maintaining premium performance, it drastically cuts energy consumption and carbon emissions in production, aligning with sustainable development initiatives.
Performance Advantages
Exceptional button pull-out strength enhances buttonhole resistance to tensile force, reduces button detachment incidents, and greatly lowers apparel after-sales repair and return rates.
Prominent abrasion resistance and anti-pilling properties effectively secure loose thread ends, prolong the lifespan of sewn goods, and elevate consumer satisfaction and brand image.
High surface smoothness prevents skipped stitches and thread nesting, reducing machine downtime, shortening single-garment sewing time, and decreasing after-sales return and rework expenses.
The recycled variant matches the performance of virgin thread, with reduced production energy consumption and carbon emissions, in line with the trend of sustainable and eco-friendly fashion.
