Sett Systems

SETT SYSTEMS

The number of warp threads per inch or other unit of measurement is termed the " sett." There are at least 14 different sett systems and each is denoted by the locality in which it is used. Bradford System - Number of beers of 40 threads in 36-in. Thus 72 sett Bradford = 72 X 40 : 36 = 80 ends per inch. Leeds - Number of porters of 38 threads in 9-in. Thus 12 porter sett = 12 X 38 : 9 = 5.06 threads per inch. Huddersfield - Dents per inch X ends per dent, thus 16's reed 3's means that there are 16 dents per inch with 3 threads per dent = 48 threads per inch. Dewsbury - Number of beers of 38 threads in 90-in. Bolton - Number of beers of 40 threads each in 24¹/₄-in. Manchester - Number of splits of two threads each in 36-in. Stockport - Number of dents of two threads in 2-in. The Stockport sett is the most convenient as the reed count or sett indicates directly the number of threads per inch in the reed without calculation providing the reeding is uniformly two ends per dent. Blackburn - Number of beers of 40 threads in 45-in. Glasgow - Number of dents two threads per dent in 37-in. Scotch Tweed - Number of porters of 40 threads in 37-in. Linen (Ireland) - Number of dents of two threads each in 40-in. These are given as 12⁰⁰, 14⁰⁰, etc. Sett 12⁰⁰ for example has 1,200 X 2 : 40 = 60 threads per inch. Silk - Number of dents in 36-in., thus 1,200/4 silk sett = 1,200 X 4 - 36 = 133 ends per inch.
