1. Classification by Intermingling / Texturing Type (Most Common)
DTY (Draw Textured Yarn): The standard low-elastic yarn, offering moderate bulkiness and low elongation properties.
DTY + Network (Intermingled Yarn): Characterized by network points along the yarn that provide excellent cohesion, preventing fraying during weaving. Commonly categorized as:
NIM (Normal Intermingled): Light intermingling with fewer nodes.
SIM (Semi-Intermingled): Medium intermingling.
HIM (High Intermingled): Heavy intermingling with frequent nodes, often used as a substitute for twisting.
2. Classification by Cross-Sectional Shape
Round DTY: The most common type, featuring a smooth surface.
Trilobal DTY: Trilobal cross-section providing a bright luster and slightly firmer hand feel. Often used for reflective or decorative webbing.
Cationic DTY (CD Yarn): Partially modified for cationic dyeing. Allows for two-tone color effects (bi-color dyeing).
3. Classification by Function / Finish (Relevant to UV Resistance)
Regular DTY: Standard yarn without UV protection.
UV-Stabilized DTY: Formulated with UV stabilizer masterbatch; the preferred choice for outdoor webbing to prevent degradation and fading.
Flame Retardant (FR) DTY: Engineered to resist ignition.
Anti-Static DTY: Treated to reduce static build-up.
Recycled DTY (rPET DTY): Made from recycled polyester, commonly used in products requiring GRS (Global Recycled Standard) certification.
4. Classification by Luster
Semi-Dull DTY: The most versatile option; widely used for general outdoor webbing.
Full-Dull DTY: Non-reflective (matte finish), offering a premium, “sun-protective” aesthetic.
Bright DTY: High-gloss finish, typically used for decorative webbing on bags and apparel.
5. Classification by Linear Density (Denier)
Common Specs: 75D/72F, 100D/96F, 150D/144F, 300D/576F, etc.
