What is Bonded Polyester Thread 69#? (H3)

Bonded Polyester Thread 69#, commonly referred to as “69# Polyester,” is a high-performance sewing thread made from continuous filament polyester fibers. Its name, “69#,” indicates its thickness or weight, with a higher number representing a thicker thread. The bonding process enhances its durability, making it less likely to fray, shed lint, or break during sewing operations. This thread is widely recognized for its outstanding performance in a variety of applications due to its unique attributes.

Top 4 Characteristics of Bonded Polyester Thread 69#

  1. High Strength and Tenacity: Bonded Polyester Thread 69# is known for its exceptional strength and tenacity.
