Textile Term: Vibroscope

A vibroscope is an instrument that measures the linear density of individual textile fibers, which is important in determining the quality and performance of textile products. This method is useful for both natural and synthetic fibers, but it is particularly effective for man-made fibers like polyester and nylon.

The vibroscope method involves measuring the natural frequency of vibration of a fiber that is clamped at one end and free to vibrate at the other end. The frequency of vibration is related to the tension, length, and mass per unit length of the fiber, and can be used to calculate the linear density of the fiber.

However, the frequency of vibration can be influenced by several factors, so adjustments must be made to obtain accurate results. For example, the elasticity and stiffness of the fiber, as well as the shape and dimensions of the clamping mechanism, can affect the actual frequency of vibration.

To obtain reliable results, the fibers being tested must be straight and parallel, without any kinks or curls. This can be achieved by carefully preparing the fiber samples, such as by combing or stretching the fibers.

The vibroscope method is an important tool for ensuring the quality of textile products by accurately measuring the linear density of individual fibers.
