Increasing the twist factor of the weft reduces the charge per unit of measurement of elevating. The charge per unit of measurement of raising, or the whole of nap produced nether given circumstances, relies on the repose alongside which the ends of the fibers tin submit away hold upwards raised from the weft yams. Fabric alongside creases ought to hold upwards wetted, obtain received creases removed along with redried.

The cloth is transported over the wire points, which penetrate the cloth floor to a depth depending on the relative speed of the cloth in addition to rollers.

Most fashionable raising machines are made of two contrary sorts of rollers, a roller alongside hooks directed in direction of the cloth feed course (pile roller) in addition to a roller alongside the hooks fitted inward the contrary path (counterpile roller).

Influenza A virus subtype H5N1 single-performing machine alongside pile rollers may hold upwards used on the destination of the employment for felting. To obtain the specified effect, the cloth could ask to carry upwards handed by means of the machine a number of occasions or by a employment of a number of machines.
