TOP 5 Covered Elastic Yarn Manufacturers in China( In No Particular Order )
When textile manufacturers need elastic yarn for socks, underwear, leggings, sportswear, gloves, shoe uppers, or elastic tapes, covered elastic yarn is one of the common yarn structures used in production. It combines a spandex core with nylon or polyester filament, giving the yarn stretch while the outer filament provides the surface needed for knitting or weaving.
China has a large covered yarn manufacturing base, especially in Zhejiang and other textile production areas. For overseas buyers, the important part is finding a covered elastic yarn manufacturer that can provide the required yarn structure, material combination, specifications, packaging, and bulk supply.
Here are five Chinese manufacturers worth considering when sourcing covered elastic yarn suppliers in China.
Zhejiang Kangjiesi New Material Technology Co., Ltd.
For buyers searching for a covered elastic yarn manufacturer in China, Zhejiang Kangjiesi New Material Technology Co., Ltd. is one company to consider. KJS Yarn focuses on covered yarn and customized elastic yarn production, supplying textile manufacturers and distributors for different stretch-fabric applications.
Its product range includes Single Covered Yarn, Double Covered Yarn, Air Covered Yarn, Rubber Yarn, Nylon Yarn, and Spun Yarn. The covered elastic yarn can use a spandex core with nylon or polyester filament, with different yarn counts and material combinations available for specific production requirements.
For a China covered elastic yarn supplier, this range is useful because buyers do not always need the same covering structure. SCY uses one covering layer, while DCY uses two layers. The choice can be made according to the required stretch, yarn structure, fabric construction, and knitting process.
KJS also supports custom covered elastic yarn production. Buyers can discuss denier, covering material, twist direction, color, cone size, labeling, and packaging according to their production requirements. OEM orders and bulk supply are also available.
The company's covered yarn products are used in socks, seamless garments, underwear, sportswear, elastic fabrics, gloves, shoe uppers, and elastic tapes. This makes KJS suitable for textile factories that need different covered yarn specifications for several product lines.
Zhejiang Huafeng Spandex Co., Ltd.
Zhejiang Huafeng Spandex is a Chinese spandex manufacturer based in Zhejiang. Its business focuses on spandex fiber products used in textile production, including applications that require elasticity and recovery.
For buyers comparing elastic yarn suppliers in China, Huafeng is more closely connected with the spandex material side of the supply chain. Its products can be relevant to apparel, hosiery, medical textiles, and other stretch applications.
When sourcing covered elastic yarn, buyers should distinguish between a spandex producer and a finished covered yarn factory. The latter handles the covering process and supplies the finished yarn directly to knitting or weaving factories.
Jiangsu Haixin Fiber Co., Ltd.
Jiangsu Haixin Fiber is another company that can be considered when researching covered yarn manufacturers in China. The company is involved in elastic fiber and yarn production for textile applications.
For B2B buyers, Jiangsu-based suppliers can be useful when the project requires elastic materials for apparel and knitted fabrics. Before placing an order, buyers should confirm the exact covered yarn structure, available denier combinations, covering material, MOQ, and production lead time.
For long-term supply, it is also worth checking whether the supplier can provide samples before bulk production and maintain the same specification for repeat orders.
Zhejiang Hailide New Material Co., Ltd.
Zhejiang Hailide is a textile material manufacturer with products covering industrial and textile applications. Its business includes polyester and other synthetic fiber materials used across different textile sectors.
It is relevant to buyers researching China elastic yarn manufacturers because polyester-based textile materials are commonly used in stretch fabric production. Buyers looking for covered yarn should confirm whether the required finished yarn construction is available directly or needs to be produced through a customized order.
For OEM textile projects, material selection, yarn count, color, packaging, and final fabric application should be discussed before quotation.
Zhejiang Jiaren New Materials Co., Ltd.
Zhejiang Jiaren New Materials is another Chinese textile-material company worth including in a broader supplier search. The company works with functional and recycled textile materials and serves different textile production applications.
For buyers comparing covered elastic yarn suppliers in China, companies with different synthetic-fiber capabilities can be useful when a project involves specific material requirements. However, buyers should check the actual covered yarn product range rather than assuming every fiber manufacturer supplies finished SCY or DCY.
This is especially important for OEM purchasing, where the required yarn structure may be different from the supplier's standard product catalog.
What Should Buyers Check When Sourcing Covered Elastic Yarn?
The first thing to confirm is the yarn structure. Single Covered Yarn and Double Covered Yarn are not interchangeable in every textile process. The number of covering layers changes the yarn construction and can affect how it behaves during knitting.
The second point is the covering material. Nylon and polyester are common choices, but the selection depends on the final fabric and processing requirements.
The third point is the spandex specification. Denier, stretch requirement, yarn count, and covering filament need to be considered together rather than selected separately.
For B2B orders, buyers should also ask about custom elastic yarn, MOQ, sample availability, cone packaging, production capacity, lead time, and repeat-order supply.
Types of Covered Elastic Yarn
1. Single Covered Yarn (SCY)
SCY uses one covering filament around the spandex core. It offers a relatively simple yarn structure and is commonly selected for socks, knitted fabrics, underwear, and other stretch textile products.
2. Double Covered Yarn (DCY)
DCY uses two covering filaments around the spandex core, with the covering layers generally arranged in opposite twist directions. This construction provides a different yarn structure for applications requiring controlled stretch and covering performance.
3. Air Covered Yarn (ACY)
ACY combines spandex with nylon or polyester filament through air interlacing. It is used for hosiery, sportswear, seamless garments, and other applications where the yarn needs to pass through continuous knitting processes.
Nylon vs. Polyester Covered Elastic Yarn
1. Nylon Covered Elastic Yarn
Nylon is commonly used when the finished textile requires a softer surface and flexible hand feel. It is frequently selected for socks, hosiery, underwear, seamless garments, and other close-fitting textile products.
2. Polyester Covered Elastic Yarn
Polyester-covered yarn is suitable for textile products using polyester-based constructions. It can be found in sportswear, knitted fabrics, denim, and other stretch fabric applications.
3. Processing Considerations
Nylon and polyester can behave differently during dyeing, knitting, and finishing. Buyers should consider the existing textile process, machine conditions, and fabric construction when selecting the covering filament.
4. Application-Based Selection
The choice is not simply between nylon and polyester. Textile manufacturers should consider the required elasticity, surface characteristics, fabric composition, color requirements, and final product before selecting the yarn material.
Covered Elastic Yarn Applications
1. Hosiery
Covered elastic yarn is widely used in socks, tights, pantyhose, and other hosiery products. The yarn provides the stretch needed for fabric construction and fitting.
2. Sportswear & Activewear
Sportswear manufacturers use covered elastic yarn in leggings, athletic garments, stretch fabrics, and other products requiring elastic textile construction.
3. Seamless & Underwear
SCY, DCY, and other covered yarn structures can be used for seamless garments, underwear, swimwear, and close-fitting apparel where controlled stretch is required.
4. Other Textile Products
Additional applications include shoe uppers, gloves, elastic tapes, knitted fabrics, and stretch accessories. The required yarn structure and specification can vary according to the production machine and final fabric design.
