The role of sheep breed and mohair style and character in the OFDA curvature vs staple crimp/wave frequency relationship. (Reprinted from the 10th International Wool Textile Conference, Germany, November 2000)

Wool crimp and mohair waviness affect fibre quality, processing behaviour a nd product properties and it is important that these properties be measured . The OFDA and other systems, such as the Sirolan Laserscan, allow fibre cr imp land associated fibre parameters, such as wool bulk, etc.) to be estima ted in a practical manner. However, it is not yet known how certain factors , such as sheep breed or mohair style and character, affect the OFDA curvat ure vs staple crimp/mohair wave frequency relationship. This has been studi ed and reported on in this paper. A fairly good relationship was found to exist between the OFDA curvature an d staple crimp/wave frequency for both wool and mohair. It is concluded tha t the OFDA curvature can be used as a measure of wool staple crimp and moha ir wave frequency without the need to take either sheep breed or mohair sty le and character into consideration.
