Modal fibers are known for their softness, excellent moisture-wicking properties, and sustainability as they are made from beech tree pulp. Polynosic fibers have a silk-like smoothness, high luster, and good drape, making them suitable for high-end apparel. Both fibers are breathable, offer good color retention, and are relatively easy to care for.

What is Calvin Klein signature fabric?

Calvin Klein is known for using high-quality fabrics such as cotton, Modal, and Spandex in their collections. However, one of the most iconic signature fabrics associated with Calvin Klein is their use of stretch denim in their jeans, known for its comfortable fit and durability.


Will a shirt shrink if its made of 50 percent Modal and 50 percent cotton?

Its a natural product and just like cotton it draws up a great deal. I would be very careful. Cotton by itself will draw up and Modal is made of cellulose from beech trees which is very porous and needs certain care.


What is modal vibration and spectral vibration?

An individual mode is a particular frequency and phase (direction) of vibration. Spectral vibration is were you take a particular vibration time-wave form and view its individual frequency components using a process called fast fourier transform (FFT). Individual frequency components can be assessed using software packages such as System1, VibroNurse, Prism4, Machine Analyst to assess machinery/structural conditions.


How do you deterrmine a natural frequency?

To determine the natural frequency of a system, you typically need to know the system's mass, stiffness, and damping characteristics. These parameters are used to formulate the system's differential equation of motion, which can then be solved to find the natural frequency. Alternatively, experimental modal analysis techniques such as impact testing or frequency response testing can also be used to determine the natural frequency of a system.


What are the fabrics in a t-shirt?

T-shirts are typically made from cotton, polyester, or a blend of both fabrics. These fabrics are chosen for their breathability, comfort, and ability to retain their shape after washing. Occasionally, t-shirts may also be made from fabrics like rayon, modal, or spandex for added stretch and softness.
