• Crimp and bulk

    Chapter 2 - Cotton value addition - The impact of cotton fibre properties on textile 

    Fibre crimp (waviness or undulation), which is largely determined genetically, can be expressed in terms of crimp frequency and amplitude, as well as in terms of decrimping force and crimp extension (crimp per cent). Cotton fibres vary in crimp and bulk, but there is little evidence that the variations in crimp generally encountered have a significant effect on cotton processing performance and yarn quality. A high recovery from compression is regarded as a prerequisite for good carding.
