what is the crimp? 

fiber crimping prevents flattening and clumping of the fibers. two main types of crimp are Mechanical and Conjugate (chemical):

  • mechanical crimping - typically the lower cost crimping method resulting in a sawtooth pattern and created by heat and pressure

    • less costly but less durable as well ​

    • oddly, used in micro-denier fibers which are one the most expensive fibers but the use of mechanical crimp is due to the tiny size of the fiber

  • conjugate crimping - chemical crimping of the fiber using 2 different polymers resulting in a spiral shape 

    • the more costly and more durable crimp method​
