Application of Polyester Fiber in Non-woven Fabrics
Polyester, scientifically known as polyethylene terephthalate (PET). It is a thermoplastic polymer widely utilized in various applications. It is a pivotal material in the production of non-woven fabrics through the spun-bond method. In China, the output accounts for about 6% of the total output of spun-bond non-woven fabrics. 1. Molecular Structure of PET PET molecules […]
Understanding the Differences Between DTY, FDY, and POY
When it comes to synthetic fibers like polyester, there are three main types to know about DTY, FDY, and POY. 1. DTY DTY for Draw Textured Yarn. It is made by intertwining single fibers through a process involving compressed air. It results in long strands with periodic network points. These fibers often have some elasticity […]
Understanding Flame Retardancy: Oxygen Index vs. UL94 Ratings
The Oxygen Index (OI) refers to the minimum concentration of oxygen needed for a material to sustain flame combustion in a mixture of oxygen and nitrogen gases under specific conditions. It is expressed as a percentage of oxygen volume. 1. What is the Oxygen Index (LOI)? The Oxygen Index indicates the oxygen concentration required for […]
A Simple Guide to Weft Yarn Sizing for Color Woven Fabrics
The article introduces a new method for treating weft yarn in color-woven fabrics. It involves three steps: dyeing the yarn, applying a liquid sizing agent, and drying it. Let’s break it down: Step 1: Dyeing the Yarn First, we dye the yarn in the usual way. Then, we add a softening agent and dye the […]
