Polyester DTY Yarn 150D/48F 100%-Virgin Seamless Knitting

150D/48F Polyester DTY Yarn Overview

Longtai manufactures 150D/48F 100% virgin polyester draw textured yarn (DTY) designed for seamless knitting and weaving operations. This yarn is produced using precision texturing technology, resulting in consistent tensile strength and controlled elasticity. The yarn creates fabrics with a soft hand feel and resistance to pilling, suitable for various textile production processes. It is compatible with high-speed circular knitting machines and weaving equipment, supporting continuous production runs.

Core Technical Specifications of 150D/48F Polyester DTY Yarn

Performance Advantages of 150D/48F Polyester DTY Yarn

Controlled Elasticity and Dimensional Stability

This polyester DTY yarn exhibits 6-8% elastic recovery, which prevents excessive stretching and bagging in finished garments. The controlled stretch provides sufficient flexibility for activewear while maintaining fabric shape through repeated use and washing. It also delivers superior loop stability in circular knitting machines, reducing fabric defects during production.

Color Retention Properties

Dope-dyed variants of this yarn achieve Grade 4-5 colorfastness according to ISO 105-C06 testing standards. This level of color retention reduces fading from washing and UV exposure, extending the usable life of outdoor textiles and apparel. Using dope-dyed yarn can also reduce dyeing costs by approximately 40% for commercial operations.

Production Efficiency

The yarn has a breakage rate of less than 2% at weaving speeds of 30 meters per minute, reducing machine downtime and material waste. The uniform oil content of 0.4±0.1% minimizes residue buildup on textile machinery, decreasing maintenance requirements. Consistent yarn evenness (CV% <1.2) ensures uniform fabric appearance across production runs.

Finished Fabric Characteristics

Fabrics produced from this yarn achieve an anti-pilling rating of ≥4.5 when tested according to ASTM D4970 standards. The yarn also provides moisture-wicking properties, making it suitable for performance apparel applications.

Applications of 150D/48F Polyester DTY Yarn

Performance Apparel

This yarn is used in the production of yoga wear, running shirts, and seamless underwear. Its stretch recovery properties maintain garment fit through 50+ wash cycles, while the anti-pilling surface preserves fabric appearance.

Home Textiles

The yarn is suitable for woven curtain sheers and anti-pill fleece blankets. The UV-resistant color properties of dope-dyed variants make them appropriate for use in sunlit rooms.

Technical Textiles

It is utilized in medical compression fabrics and automotive interior liners. OEKO-TEX certified options are available for applications requiring compliance with textile safety standards.

Frequently Asked Questions About 150D/48F Polyester DTY Yarn

What is the difference between DTY, FDY, and POY yarn?

DTY (Draw Textured Yarn) has higher bulkiness and elasticity compared to FDY (Fully Drawn Yarn) and POY (Partially Oriented Yarn). This makes DTY more suitable for applications requiring stretch and softness.

Can this yarn be used for both knitting and weaving?

Yes, the 150D/48F specification is compatible with both circular knitting machines and weaving equipment, providing versatility for textile manufacturers.

What certifications are available for this product?

Standard certifications include SGS and OEKO-TEX. GRS (Global Recycled Standard) certification can be provided upon request for specific orders.
