Description

Polyester sizing formula refers to the process of applying a sizing agent to polyester fibers or fabrics to improve their handling, weaving, and overall performance during textile production. Sizing is especially important for polyester because it is a synthetic fiber with a smooth surface, which can make it more challenging to handle during weaving or other textile processes.

key points about polyester sizing formula

  1. Sizing agent selection: The choice of sizing agent depends on various factors such as the specific application, desired fabric properties, and machinery used. Common sizing agents for polyester include modified starches, synthetic polymers, or a combination of both. These sizing agents provide lubrication and adhesive properties to the polyester fibers, making them easier to handle during weaving or subsequent processing steps.
  2. Sizing process: The sizing process involves applying the sizing agent to the polyester fibers or fabrics. This can be done through various methods, such as immersion, padding, or spraying. The fibers are typically passed through a sizing bath or solution containing the sizing agent, ensuring uniform coverage. Excess sizing solution is usually removed by squeezing or drying to achieve the desired level of sizing.
  3. Sizing film formation: The sizing agent forms a thin film or coating around the polyester fibers, providing lubrication and protection during weaving. This film helps reduce friction between the fibers, prevents fiber breakage, improves yarn strength, and enhances the fabric’s overall performance.
  4. Impact on fabric properties: Polyester sizing can affect various fabric properties, including yarn strength, abrasion resistance, and dimensional stability. Proper sizing can help control yarn slippage, improve the fabric’s appearance, and reduce the occurrence of yarn breakage during weaving.
  5. Drying and curing: After the sizing agent is applied, the polyester fibers or fabrics are typically dried or cured to remove excess moisture and allow the sizing film to adhere properly. Drying can be done through natural air drying or using heated drying methods, depending on the sizing agent used and the specific requirements of the process.
  6. Sizing removal: In some cases, the sizing agent needs to be removed from the polyester fabric after weaving or prior to dyeing or finishing. This can be achieved through processes like desizing or scouring, which involve the use of appropriate chemicals and washing techniques to dissolve or remove the sizing film.
