Knop yarn

A yarn that contains prominent bunches of one or more of its component threads, arranged at regular or irregular intervals along its length.
Note 1: The yam is usually made by using two pairs of rollers, capable of being operated independently, as follows:
(i) foundation threads-intermittent delivery;
(ii) knopping threads-continuous delivery. The knopping thread(s) join(s) the foundation threads below the knopping bar and is (are) gathered into a bunch or knop by the insertion of twist.
Note 2: The knop yarn may be bound with a thread in the direction opposite to the initial stage to secure the knops and/or to produce an additional spiral between the knops.(Sub Category of Fancy Yarn)

Kusters Dyeing Range

Continuous dye range for carpets.
