BLACK MASTERBATCH - PET/ PBT MASTERBATCH

BLACK MASTERBATCH – PET/ PBT MASTERBATCH

For Cotton Type Fiber & Polyester Filament Yarn (FDY, DTY, POY)

Product Overview

Our Polyester-Based Black Masterbatch is specifically engineered for high-performance fiber and filament applications, including cotton-type polyester fibers, FDY, DTY, and POY yarns.

The formulation is based on PET resin with a liquid solvent black pigment, ensuring deep jet-black coloration, excellent dispersion, and thermal stability during melt spinning and fiber extrusion processes.

Composition & Technical Structure

Application Fields

  • Cotton-Type Polyester Fiber (staple fiber for spinning)
  • Filament Yarn Production – FDY, DTY, and POY processes
  • Textured Yarns and Microfibers
  • High-speed spinning applications

Physical & Performance Data

 

Key Features & Benefits

  • Deep Jet Black tone with superior gloss and opacity
  • Perfect pigment dispersion due to liquid solvent-based pigment system
  • No filter clogging or pigment agglomeration during melt spinning
  • Excellent thermal and light stability
  • High color consistency even at high-speed spinning (up to 6000 m/min)
  • No migration or blooming on final products
  • Compatible with all polyester spinning systems (FDY, DTY, POY, and staple fibers)

Processing Guidelines

  1. Drying: Dry masterbatch at 120°C for 4 hours before use.
  2. Dosage: Add 0.8–2% depending on desired shade and opacity.
  3. Mixing: Mix uniformly with virgin PET chips before feeding into extruder.
  4. Processing Temperature: 270–295°C for best melt flow and color uniformity.

Packaging & Storage

  • Supplied in 25 kg multilayer bags with inner PE liner.
  • Store in a dry, cool place (below 40°C) away from direct sunlight.
  • Reseal bags tightly after use to avoid moisture absorption.

Technical Highlights

  • Compatible with melt spinning, microfiber production, and textured yarn processes.
  • Solvent pigment technology ensures improved gloss, black depth, and dispersibility compared to traditional carbon black systems.
  • Custom shades and formulations are available upon request (e.g., matte black, super jet black).
