1. The operation of passing the weft through the warp shed during weaving. 2. The rectification of the face and back of a carpet after manufacture including inserting missing tufts replacing faulty ones, and repairing broken yarns in the backing. Also known as 'mending'. 3. A process preferably carried out before the final stage of fabric finishing, which involves removing by hand any contamination (such as kemp, wrong fibre, coloured hair, etc.) which has not been removed by previous processing. This process is carried out particularly during the finishing of suitings, face-finished fabrics, and cream or off-white fabrics. 4. See scutching (cotton).
The final operation in the cotton system preparation line, in which the cotton flocks are opened mechanically, cleaned, and formed into a lap of specified mass per unit area, for feeding to a carding machine. Note: Scutching (picking) machines are being extensively replaced by the combination of opening and cleaning machine units followed by chute feeding.
