TOP 5 Air Covered Spandex Yarn Manufactures

TOP 5 Air Covered Spandex Yarn Manufacturers( In No Particular Order )

When a textile factory needs stretch yarn for socks, seamless garments, sportswear, denim, or knitted fabrics, Air Covered Yarn (ACY) is one of the yarn structures worth comparing. Unlike mechanically covered yarn, ACY uses compressed air to interlace the spandex filament with nylon or polyester filament. The yarn structure is formed through air interlacing, which gives the yarn a different surface and processing behavior from SCY and DCY.

For B2B buyers, choosing an ACY supplier is not only about the yarn specification. Production capacity, available denier combinations, covering material, color, package, MOQ, sample service, OEM capability, and batch consistency all affect whether the yarn can run smoothly in commercial textile production.

This article looks at five companies involved in air covered spandex yarn manufacturing and supply, with the first one being Zhejiang Kangjiesi New Material Technology Co., Ltd., also known as KJS Yarn.

Zhejiang Kangjiesi New Material Technology Co., Ltd. 

For buyers looking for an air covered spandex yarn manufacturer in China, Zhejiang Kangjiesi New Material Technology Co., Ltd. (KJS Yarn) is a manufacturer worth considering. The company focuses on covered yarn and elastic yarn production, supplying yarn for socks, seamless garments, sportswear, denim, knitted fabrics, shoe uppers, and other stretch textile applications.

KJS supplies Air Covered Yarn in both nylon-spandex and polyester-spandex constructions. The yarn is produced by interlacing spandex with nylon or polyester filament through compressed air. This gives textile manufacturers different options when selecting yarn according to fabric construction, elasticity requirements, and knitting conditions.

Air Covered Spandex Yarn for Textile Production

KJS offers different ACY specifications, including Nylon Spandex ACY and Polyester Spandex ACY. Examples include 2070, 2075, 3075, 4075, 20150, and other combinations.

For B2B buyers, the advantage is being able to select the spandex denier and covering filament according to the final product. 20D air covered yarn can be used in lightweight stretch fabrics, socks, pantyhose, leggings, seamless garments, and sportswear, while heavier specifications can be selected for applications such as denim and other knitted fabrics.

Custom Air Covered Yarn for OEM Orders

KJS also provides custom air covered yarn for textile manufacturers. Buyers can discuss spandex denier, nylon or polyester covering material, yarn specification, color, package, and other production requirements.

For companies searching for an air covered yarn supplier, covered yarn manufacturer in China, or OEM air covered yarn factory, this type of customization is useful when standard specifications do not match an existing fabric or knitting process.

KJS also produces Single Covered Yarn, Double Covered Yarn, functional covered yarn, nylon yarn, and other elastic yarn products. Buyers sourcing several yarn structures can therefore discuss different requirements with the same China covered yarn supplier.

Air Covered Yarn for Hosiery and Sportswear

KJS lists socks, seamless garments, sportswear, underwear, swimwear, denim, and shoe upper fabrics among the application areas for its covered yarn products.

For a hosiery yarn supplier, the yarn structure, spandex denier, covering filament, and knitting conditions all need to match the final fabric. KJS can provide different ACY constructions for buyers developing stretch textile products and bulk production orders.

For B2B sourcing, buyers can send the required yarn specification, application, color, package, and expected quantity when requesting a quotation. This gives the air covered spandex yarn supplier a clearer basis for recommending or producing the required yarn.

Zhejiang Xingfa Chemical Fiber Group Co., Ltd.

Zhejiang Xingfa Chemical Fiber Group is another company that buyers can consider when comparing air covered spandex yarn suppliers in China.

The company works with synthetic fiber products and air covered yarn applications. Its product range includes yarn constructions combining spandex with synthetic filaments, giving textile manufacturers options for stretch fabric production.

For buyers comparing suppliers, Xingfa is more relevant when the project requires synthetic filament combinations and an established textile production supply chain in Zhejiang.

When contacting an air covered yarn supplier, buyers should confirm the available spandex denier, covering filament, yarn count, color, MOQ, package, and whether customized specifications can be produced for the intended knitting process.

Zhuji Jinzong Knitting Co., Ltd.

Zhuji Jinzong Knitting is based in Zhuji, Zhejiang, a major textile manufacturing area in China. The company supplies covered yarn products including single covered yarn, double covered yarn, and air covered yarn.

Its products are used in socks, swimwear, sportswear, lingerie, seamless underwear, medical bandages, and stretch fabrics.

For buyers looking for an air covered yarn manufacturer in China, Zhuji's location is also relevant because the city has a strong hosiery and textile manufacturing supply chain. This can make communication around knitting applications and yarn specifications more direct.

Before placing an OEM order, buyers should confirm whether the required ACY specification is part of the standard range or needs custom production.

INVIYA™ Spandex

INVIYA™ is a spandex brand associated with Indorama India. Its spandex materials are used in textile applications that require stretch and recovery, including yarn and fabric production.

For an air covered spandex yarn supplier, the distinction between finished ACY and spandex raw material is important. Companies such as INVIYA are more relevant when a buyer is evaluating the spandex component used in the covered-yarn production process.

Textile manufacturers developing their own ACY production or comparing spandex raw materials may consider factors such as denier, elongation, recovery, heat resistance, and processing compatibility.

Hyosung

Hyosung is another major spandex producer known across the textile supply chain. Its spandex products are used in apparel, hosiery, sportswear, underwear, and other stretch textile applications.

For buyers searching for air covered spandex yarn manufacturers, Hyosung should be viewed differently from a dedicated ACY factory. The company is primarily relevant as a spandex material supplier rather than a finished air covered yarn manufacturer.

This difference is worth keeping in mind when comparing suppliers. A finished ACY factory can provide the complete spandex-plus-covering-filament yarn, while a spandex producer mainly supplies the elastic core material used by yarn manufacturers.

How to Choose an Air Covered Spandex Yarn Manufacturer

A good supplier comparison starts with the yarn specification.

1. Check the spandex denier

The spandex denier affects the stretch level and yarn construction. Common specifications include 20D, 40D, and heavier counts for different textile products.

2. Check the covering filament

Nylon and polyester do not behave the same way in textile production. The covering material should be selected according to fabric construction, surface requirements, dyeing process, and final application.

3. Compare ACY with SCY and DCY

Air Covered Yarn, Single Covered Yarn, and Double Covered Yarn use different covering structures. The selection should be based on knitting conditions, stretch requirement, fabric construction, and production cost.

4. Ask about OEM and custom production

For B2B buyers, a supplier that can adjust denier, filament combination, color, packaging, and other specifications can be more useful for long-term production projects.

5. Confirm bulk supply

Always ask about MOQ, monthly capacity, lead time, sample availability, packaging, shipping port, and repeat-order capability before confirming a large purchase.
