Method of Short Fibre Drafting

In this case, the rovings are not very cohesive or strong, therefore drafting must necessarily be very reduced (usually carried out at rates of between 20% and 50%) and supported by special fibre control devices. The shorter length of the raw material does not generally allow the fibres to be nipped by the pair of feeding cylinders or by the delivery cylinder, therefore resulting in a high percentage of floating fibres. Indeed, very short fibres do not fit the ideal pattern of behaviour within
