Spun yarn for socks, knitting, and weaving from Longtai
Longtai supplies polyester staple‑spun yarns and sock yarn made in Datang Town, Zhuji, Zhejiang, China. The range supports socks, scarves, and apparel. We provide OEM/ODM customization and 24‑hour online support. Production is aligned to knitting efficiency and consistent performance from development to bulk.
What it is and why it matters
Spun yarn is formed by twisting staple fibers into a cohesive thread. Compared with filament, it feels softer and more natural, covers well, and dyes evenly. These traits suit socks and everyday knitwear where breathability, durability, and steady machine behavior are important. For comfort‑focused fabrics, polyester staple‑spun options offer a practical balance.
Why choose Longtai
Based in Zhejiang, we pair steady quality with flexible production, fast color response, and on‑time delivery. The digital showroom shows real manufacturing scenes for transparency. We support swift sampling and technical guidance, aligning schedules and specifications with your program.
Polyester spun yarn options
This range is engineered for stable knitting and weaving. Options include raw white for dyeing and ready‑to‑use black and yellow for faster throughput. We tailor count, twist, and ply to match sock lines and knitting gauges for balanced strength and hand feel.
Color availability and consistency
Choose raw white, black, and yellow, or request custom shades to meet brand or mill requirements. Controlled dyeing and batch management help minimize lot‑to‑lot variation, supporting smoother production and fewer reworks.
Count, twist, and ply matching
We support fine to medium counts with S/Z twist and single or plied constructions. Our team advises on count and twist selection to optimize knitting efficiency, fabric uniformity, and comfort.
Supported count systems
We work with common systems such as Ne, Nm, and tex. Requirements can be translated into your preferred standard so purchasing, QC, and production stay aligned.
Applications
Polyester staple‑spun yarn from Longtai is optimized for socks, hosiery, scarves, sweaters, and general knitting and weaving. Abrasion resistance and stable runnability support high‑speed circular knitting and sock machines, helping reduce downtime and promoting an even appearance.
Socks and hosiery
For rib, terry, and seamless socks, the yarn forms dependable stitches and a comfortable touch, pairing well with elastic components for cuff recovery. Consistent cone build and winding help reduce end breaks and support steady machine utilization.
Scarves and apparel
For scarves, sweaters, and everyday apparel, polyester options balance softness, wrinkle resistance, and color fastness. Solid shades and heather looks can be achieved through blending and twist control within your process.

FAQs
What counts work best for socks?
Medium counts commonly used in sock knitting balance strength and comfort. Share your machine gauge and target properties, and we will recommend a suitable count and twist.
How does it differ from filament yarn in performance?
Staple‑spun yarn delivers a softer, more matte hand feel with good coverage. Filament is smoother and shinier. For socks and casual wear, staple‑spun is often preferred for comfort and absorption.
Can you support custom colors and special finishes?
Yes. We can develop custom colors and discuss finishes aligned with your process, supported by batch control and sample approval.
