6、 a yarn, a thickened place having tapering ends and a diameter several times that of the adjacent normal yarn. NOTE - This defect is often caused by the presence in the yarn of fragments of undrafted roving or slubbing that have not been cleared durfng winding. 2.6 soiled yarn: An individual yarn, i

NOTE - This defect is caused by a weft yarn breaking, running out, or being prematurely released during insertion. 3.2 duite coupee; duite rompue: Fil de trame qui nest present que dans une par-tie de la largeur du tissu. NOTE -
10、Ce defaut est cause par la rupture dun fil de trame, flottant ou ayant et6 ldcha prematurement pendant Iinsettion. 3.3 chopped weft: Weft that has been partially severed. 3.3 trame couphe: Trame qui a 6t6 pattiellement rompue.

11、 NOTE - Ce defeut est souvent cause par la rupture par le peigne lors du tissage de la duite. 3.4 coarse pick; coarse weft; thick pick: A weft yarn of substantially greater thickness than that of the adjacent weft yarns. 3.4 duite epaisse: grosse duite; grosse trame: Fil de trame plus Bpais que les

NOT
15、E - This defect is often caused by poor tension control of weft yarns during winding, unwinding or insertion. NOTE - Ce defeut est souvent cause par un manque de controle de tension du fil pendant le bobinage ou pendant Iinsertion de la trame. 3.9 mispick: Weft yarn which does not conform to the in- tended weaving pattern. NOTE - This defect is caused by an incorrect sequence of weft inser- tion. 3.9 erreur de tramage: Fil de trame qui nest pas conforme au motif tisse prevu. NOTE - Ce defaut est cause pat une anomalie dans le suivi de Iinser- tion des fils de trame. 4
