Air covered yarn, the outer fiber filament and spandex yarn are drawn through a certain type of nazzle in the same time, after high regular network of points in the yarn, the fabric feels soft and smoothAir covered yarn is manufactured by interlacing Spandex yarn with Nylon with the help of compressed air. The air is applied through a nozzle which regulates the flow. Spandex is then applied during a draw texturizing process of Polyester or Nylon to avoid the additional process of spandex application.

Longtai
Manufactured by Longtai, a trusted professional yarn supplier for global industrial production clients, the 4070D ACY Nylon Spandex Yarn 70D/24F is a top-tier air covered yarn (ACY) engineered for high-speed circular knitting, seamless garment manufacturing, and large-scale textile production. This air covered nylon spandex yarn integrates high-elasticity spandex core with premium 70D/24F nylon DTY filament through advanced compressed air interlacing technology, delivering an ultra-soft, smooth hand feel, consistent stretch, and exceptional production adaptability. Tailored for bulk purchasers and large-scale knitting factories, this product eliminates extra spandex processing steps, boosting your production efficiency while elevating the quality of your finished textiles.
Our circular knitting ACY yarn is produced with a one-step air interlacing process, integrating spandex and nylon filament in a single production line. This eliminates the need for additional spandex coating or sizing procedures in your manufacturing, cutting down processing time and labor costs for large-scale production.
The regular network points formed by compressed air ensure even distribution of spandex within the nylon filament, resulting in a fabric with exceptional softness, smoothness, and uniform stretch. This batch-to-batch consistency minimizes fabric defects and ensures a premium finish for high-end apparel products.
This 4070D nylon spandex ACY yarn is fully compatible with all mainstream circular knitting machines, looms, and seamless knitting equipment. We offer fully customizable color, packaging, and filament specification adjustments, with flexible order volumes to meet the needs of bulk industrial purchasers and long-term manufacturing partners.

Our air covered spandex nylon yarn is manufactured with state-of-the-art compressed air interlacing equipment. During production, nylon outer filament and spandex core yarn are simultaneously fed through a precision nozzle, where high-pressure compressed air forms regular, stable network points to interlock the two filaments tightly. This advanced process ensures uniform yarn thickness, stable elasticity, and a snag-free surface for high-speed knitting.
We enforce a full-process layer-by-layer quality control system to guarantee industrial-grade consistency:
Raw Material Qualification: All incoming nylon DTY and spandex raw materials are sourced from certified suppliers, with full testing for filament evenness, tensile strength, and elasticity stability.
Real-Time Production Monitoring: Our technical team conducts continuous checks on air pressure, nozzle precision, and yarn tension during production, ensuring every roll meets strict specification standards.
Finished Product Validation: Each batch undergoes comprehensive testing for network point stability, stretch recovery, and fabric forming performance, ensuring it adapts flawlessly to continuous industrial knitting operations.
This versatile ACY yarn is an ideal choice for industrial production in the following areas:
Circular Knitting Production: The core application, perfect for high-speed circular knitting machines to produce premium stretch fabrics for apparel.
Seamless Garment & Underwear Manufacturing: Delivers ultra-soft hand feel and consistent stretch for seamless underwear, shapewear, and intimate apparel.
Hosiery & Legging Production: Suitable for high-end pantyhose, leggings, and fashion hosiery that demand a smooth, non-marking fit.
Woven & Warp Knitting Fabrics: Compatible with various looms for producing stretch fabrics for sportswear, loungewear, and high-fashion apparel.
To ensure optimal performance of our 4070D ACY yarn in your industrial production:
Operation Tips: Adjust the air jet tension and feeding speed according to your knitting machine model, avoiding excessive overstretching of the yarn to maintain the stability of network points and consistent elasticity of the finished fabric. The yarn is compatible with all mainstream circular knitting and seamless knitting equipment.
Storage Requirements: Store in a closed, cool, dry environment, away from direct sunlight, high temperature, and humidity. Prevent dust and sharp objects from damaging the yarn rolls, and avoid heavy stacking to prevent filament deformation. Recommended storage conditions: temperature 15-28℃, relative humidity 35%-60%.
For standard in-stock specifications, bulk orders can be shipped within 5-7 working days. For custom color or specification orders, the lead time is 12-18 working days, adjusted based on order volume.
