Impurities

Images from a range of available jute ropes

Dark bark – hard, wiry, woody short filaments from the cane inner wall. May run for several centimetres.

Cutting – hard, sharp cane chip from harvesting

Speck – made by insects, bacteria, disease, etc. May be less than 1mm long to over a centimetre. More problematic with distribution and size.

Coarse filament – dried, brittle filament from close to the inner cane wall.

Root – a serious low strength imperfection. Dark brown or ruddy root matter grown in moist conditions. May extend over tens of centimetres.

Waste – foreign bodies, often picked up in transport, or from the factory floor.

Habijabi tangle – fibre matted at carding and spun into the yarn.

Not shown:

Break – a full break in a yarn, generally caused by breakage/loss of an impurity, especially if yarn/rope twist dynamics are excessive.

Dust – loose content twisted into the yarn, strand, and/or rope, either picked up from the factory floor, and/or process machinery, and/or environment.
