What is the difference between blank yarn and polyester yarn?

In terms of raw materials, sewing thread and Polyester Dope-dyed Yarn are all fibers made of polyester. The polyester yarn you are referring to is only polyester yarn used in conventional textiles. Sewing thread is a special polyester yarn, which is different from conventional polyester yarn in strength, shrinkage rate and elongation at break. Generally higher strength, less elongation, and lower boiling water shrinkage.

1. Nylon thread, also known as nylon thread, is made of continuous filament nylon fibers twisted together. It is smooth and soft, with an elongation rate of 20%---35%. It has good elasticity and high wear resistance. It is widely used in Sewing industrial products.

2. Polyester thread is also made of polyester raw material with high strength and low elongation. Polyester raw material is the most resistant to friction and dry cleaning among all materials. Its low elongation and low expansion rate ensure excellent seamability. Polyester sewing thread is mainly used for clothing and knitwear.
