Study on Pile Fabrics

Part 2: Structures of Pile Fabrics

Abstract

Structures and characteristics of backing layers and pile layers of pile fabrics were studied. Results obtained are as follows.
(1) Assuming that the structures of the backing layer is 3-pick terry, the basic setting value for ground warps (E_GO) and wefts (E_SO) may be expressed by: E_GO=E_G(√<G>+√<P>)/48.6 E_SO=E_S(3√<W>+2√<P>)/121.5 where the basic setting value is the end density of the pile fabric woven by ground warps 1s, wefts 1s and the pile warps 1s. E_G is the warp density, E_S the weft density. G is the yarn count of ground warps, P the yarn count of pile warps, and W the yarn count of wefts.
(2) The pile inclination (θ) may be calculated by, θ=cos^-1(1/0.33 E_S+d_p/2)/(l_h+d_p/2) where E_S is the weft density, d_p the pile diameter and l_h the pile inclination length.
(3) Frictional and compressive properties of pile fabrics were not influenced by the fabric density of the backing layer.
