Detailed Professional Description

The 75D/72F Raw White (RW) SIM (Slightly Intermingled) polyester yarn represents the pinnacle of micro-filament engineering combined with process stability. With 72 filaments in a 75 denier bundle, it features a dpf (denier per filament) of approximately 1.04. The SIM configuration introduces subtle mechanical nodes that provide essential filament cohesion for high-speed textile machinery without compromising the ultra-soft, silk-like hand feel that micro-denier yarns are known for. This yarn is a versatile base for high-density, premium fabrics in its Raw White state.

Application Fields

  • Warp Knitting: Ideal for high-speed tricot machines where micro-filaments require cohesion to prevent breakage.

  • Premium Linings: Used in luxury garment linings that demand both strength and a silky touch.

  • High-Density Weaving: Applied in "paper-touch" fabrics and ultra-light windbreakers.

  • Functional Base Layers: Used in thermal or moisture-wicking undergarments requiring high surface area.

Color & Dyeing Methods

This yarn is optimized for piece dyeing. The Raw White base is produced from high-purity virgin chips, ensuring excellent dye levelness. The micro-filament structure allows for faster dye exhaustion, which can reduce energy consumption during the dyeing cycle in commercial textile mills.
