How is the tightness of the fiber structure of Tr polyester rayon stretch fabric measured?

The tightness of the fiber structure of the fabric is a crucial performance parameter in the textile industry. It is directly related to the wear resistance, pilling resistance, and overall durability of the fabric. Especially for Tr polyester rayon stretch fabric, which is a composite fabric that combines polyester and rayon and adds stretch fiber, the tightness of the fiber structure is the key factor that determines its unique performance.

1. Definition of fiber structure tightness
Fiber structure tightness usually refers to the tightness of the arrangement between fibers and the density inside the fibers. In Tr fabric, this includes the tightness of the interweaving between polyester fibers, rayon fibers, and stretch fibers, as well as the molecular arrangement and stacking state of these fibers themselves.

2. Methods for measuring the tightness of fiber structure
Fiber density measurement: By measuring the number or mass of fibers per unit area or volume, the tightness of the fiber structure can be indirectly reflected. The higher the fiber density, the tighter the arrangement between fibers and the better the fabric performance.
Porosity analysis: Porosity refers to the proportion of voids or holes in the fabric. The lower the porosity, the tighter the arrangement between fibers and the denser the fabric.
Scanning electron microscope observation: Scanning electron microscope can be used to visually observe the microscopic morphology of the fiber surface, including the cross-sectional shape of the fiber, surface roughness and the interweaving state between fibers, so as to evaluate the compactness of the fiber structure.
Mechanical property test: Mechanical property tests such as tensile strength and tear strength can also indirectly reflect the compactness of the fiber structure. The tighter the fiber structure, the less likely the fabric is to deform or break when subjected to external force.

3. The influence of fiber structure compactness on the performance of Tr fabric
Fiber structure compactness has a significant impact on many properties of Tr fabric. The compact fiber structure can improve the wear resistance and pilling resistance of the fabric, making the fabric less prone to wear and pilling during long-term use. At the same time, the compact fiber structure can also enhance the elasticity and recovery of the fabric, so that the fabric can quickly return to its original state after being subjected to external force.

Combined with the above, it can be obtained that fiber structure compactness is one of the important indicators of the performance of Tr polyester rayon stretch fabric. Through scientific measurement methods and in-depth performance analysis, we can better understand and master the fiber structure characteristics of Tr fabric and its relationship with performance, and provide strong technical support for the production and application of fabrics.
