Manufacturing Process & Rigorous Quality Control
We exclusively source spandex and nylon fibers from long-term, vetted suppliers with verified quality management systems. Every batch of incoming raw materials undergoes comprehensive inspection for fiber strength, elasticity uniformity, and chemical compliance, ensuring only qualified materials enter our production line.
Our 7070 SCY yarn is manufactured using advanced, high-precision twisting equipment, where the spandex core is evenly wrapped with nylon filament under strictly controlled tension. We monitor twist per inch (TPI) and wrapping tightness in real time throughout production, guaranteeing consistent twist uniformity and elastic performance for every cone of yarn.
For custom color orders, we use high-quality, eco-friendly dyes with industry-leading color fastness. Our dyeing process is tightly controlled to ensure color consistency across bulk orders, with color difference held to Delta E ≤ 1.5, fully meeting the strict requirements of international garment and textile brands.
Every production batch undergoes exhaustive testing before delivery, including tensile strength, elastic recovery rate, twist uniformity, yarn evenness, color fastness, and compliance verification. We retain full samples from each batch for complete traceability, ensuring any quality concern can be tracked and resolved promptly.
Qualified yarn is packaged with export-grade moisture-proof materials to prevent damage during international shipping. We also offer fully customized packaging solutions, including cone weight, carton dimensions, and labeling, to align perfectly with your warehousing and production management needs.
Our 7070 SCY yarn is specially engineered for high-volume ribbon knitting production. Its consistent twist uniformity and stable elasticity ensure smooth feeding in high-speed ribbon knitting machines, minimizing yarn breakage and needle damage. Finished elastic ribbons deliver excellent shape retention, even stretch, and a soft hand feel, ideal for garment elastic bands, underwear ribbons, gift wrapping ribbons, and industrial elastic webbing.
This 70/70 SCY yarn is perfectly suited for manufacturing all types of elastic trims, lace, and textile accessories for garments and home textiles. Its high-tenacity nylon wrapping provides exceptional abrasion resistance, while the spandex core delivers long-lasting elastic recovery, ensuring trims maintain their elasticity after repeated washes and long-term daily use.
Widely used in seamless garments, underwear, hosiery, sportswear, and swimwear, our spandex covered nylon yarn strikes an optimal balance of stretch, softness, and durability. It works seamlessly with most circular knitting and seamless knitting machines, helping manufacturers produce comfortable, form-fitting apparel with consistent, reliable quality across every production run.
Store the yarn in a cool, dry environment, away from direct sunlight and high humidity. Proper storage conditions preserve the yarn’s elasticity, fiber strength, and overall quality over extended shelf life, preventing performance degradation before production.
Handle the yarn with care to avoid damage or excessive friction, which can cause fiber breakage or weakening. Use proper handling equipment during transport and warehousing to maintain the integrity of each cone.
Our spandex covered nylon yarn is compatible with nearly all standard industrial knitting and weaving machines. Maintain proper tension settings during operation to achieve optimal production results, minimize breakage, and ensure consistent elasticity in finished goods.
The yarn is suitable for both manual and machine knitting applications. For ribbon knitting and other elastic fabric production, calibrate yarn tension correctly during setup to achieve your desired elasticity and finished product specifications.
SCY (Single Covered Yarn) uses a twisting process to wrap filament around the spandex core, delivering higher twist uniformity and tensile strength for high-speed ribbon knitting. ACY (Air Covered Yarn) uses air jet intermingling, offering a softer hand feel for different apparel applications.
