These three carpets were dyed in each of 2 colours, namely, pink and yellow golden.
In comparison, carpet P was much duller and less shiny than carpets R and S. The dilference in brightness between carpets R and S was small. Thus the addition of a small amount of a brighter component with practically nil delustrant R to yarn with high delnstrant content provides a degree of brightness similar to that obtained with yarn with a low total delustrant content S.
Samples of the above carpets in the white, undyed state were laid in a corridor carrying a large volume of traific. After a period of two months, difierences in the rate of soiling were apparent. The carpet made from yarn with low total delustrant content S showed a significant greater degree of soiling than the other two carpets P and R made from yarns with a total high delustrant content. The differences in soiling between carpets R and P were small, with P being marginally better than R.
What we claim is:
1. A yarn comprising not less than 70% of delust'red filaments containing not less than 0.7% by weight of a delustrant and not more than 30% of bright filaments COntaining les than 0.3% by weight of a delustrant.
2. A yarn according to claim 1 wherein the filaments are polyamide filaments.
