50D–600D Product System Advantages

For label makers, webbing manufacturers, knitting mills, and industrial textile producers, yarn specifications directly affect appearance, strength, texture, and production efficiency.

Sinrylion has built a complete product system covering 50D to 600D, meeting diverse application needs from fine woven labels to heavy-duty industrial textiles. Over years of development, the company now offers more than 1000 different yarn specifications and colors, providing strong flexibility for customers.

Main product range includes:

    

• Polyester Yarn
• Polyester Twisted Yarn
• Recycled Polyester Yarn
• Label Yarn
• Nylon Twisted Yarn
• PA6 Monofilament Yarn
• TPU Monofilament Yarn
• TPEE Monofilament Yarn

Among them, the 50D/800TPM white polyester twisted yarn is widely used in woven label applications, delivering excellent weaving stability and clear pattern definition.

In terms of appearance, the product range includes: Semi Dull, Full Dull, Bright, and Trilobal Bright finishes.

Twist levels can be customized from 80TPM to 1000TPM, allowing flexible adaptation to different fabric structures and performance requirements.

High-twist yarn improves abrasion resistance and structural stability, while lower twist yarn provides softer hand feel and better coverage.
