A Geometrical Analysis of Moire Finising

Abstract

A study of the unit moire has shown that the manufacturing methods of the unit moire can be classified into two classes. Various moire patterns obtainable are:
(1) Using no-wave rules
mT=nS or m=0 and n=0 Horizontal straight strips
S=T Vertical straight strips
m=0 or n=0 Slanting strips
(2) Using wave rules
S=T and m=0 Symmetrical vertical straight strips
S=T and m_??_0 Unsymmetrical vertical straight strips
S_??_T and m=0 Symmetrical curve strips
S_??_T and m_??_0 Unsymmetrical curve strips
where S is the inverse number of counts of weft in fabric A, and T is the inverse number of counts of weft in fabric B, m is the tangent of inclination of weft in fabric A, n is the tangent of the angle of inclination of weft in fabric B.
