Product Description

43 years sinrylion Polyester yarn manufacturer

As one of the leading polyester filament yarn manufacturers, Sinrylion provides high-performance dope dyed black polyester filament yarn for global textile buyers. Our 75D/36F DTY dope dyed black yarn offers exceptional color consistency, superior tensile strength, and eco-friendly performance for high-end weaving and knitting applications.


75D/36F Dope Dyed Black Polyester Filament Yarn Core Specifications


Our dope dyed black polyester filament yarn is produced by adding black masterbatch directly into the 100% PET molten polymer before spinning. This dope-dyeing process guarantees deep black color penetration without needing secondary liquid dyeing, saving water while delivering high color fastness.


This AA Grade 75D/36F black polyester yarn features high density, soft hand-feel, and excellent wear resistance. It serves as an ideal raw material for woven patterns, circular knitting, narrow fabrics, ribbons, and industrial labels.

Customization Advantages of Dope Dyed Black Polyester Twisted Yarn


As an expert manufacturer of polyester twisted yarn, Sinrylion addresses diverse structural strength needs across textile processing. We operate around 200 specialized twisting machines to process our black filament yarn to exact technical client requirements.


We offer full customization for twist levels ranging from 80 T/M to 1000 T/M. Adding high twist enhances yarn cohesion, reduces filament breakage during high-speed weaving, and provides a textured surface for specialized fabric production.


  • Low Twist (80-300 T/M): Enhances yarn smoothness and softness for knitting fabrics and smooth linings.

  • Medium Twist (300-600 T/M): Provides balanced strength for general weaving, label manufacturing, and webbing.

  • High Twist (600-1000 T/M): Maximizes yarn toughness, snag resistance, and crisp fabric hand-feel for heavy-duty industrial textiles.
