On the fibre or yarn sliding around a cylinder, the relation of the initial tension to the final tension is given by the following equation (i. e. belting equation): where T is the final tension of fibre or yarn, T₀ is the initial tension of fibre or yarn, θ is the lapping angle of fibre or yarn against the cylinder, ρ is the radius of the cylinder, N is the frictional index, a is the constant. From the above equation, one method for calculating the approximate value of the frictional index is stated below.
1) The following equation is derived from the eqation (1): Let then a graph having gradient N and passing through the origin of the coordinate would be expected.
2) The method of the simplest calculation may be expressed by where x_i and y_i are the values based on the experimental data.
3) The value of dT/dT₀ can be obtained by the gradient of two consecutive points given in the experimental data. Then a method for estimating the value of T/T₀, is to obtain the mean value of T/T₀ for the two consecutive points.

It was previously reported by us^1)-4), that α-CH…X-Dye type hydrogen bonding plays an important role in the interaction between aminoanthraquinone type disperse dyes and ester type fibres.
In order to obtain an answer to “What is X in this bonding?”, the interaction between dyes and esters, amines and phenols are discussed in this paper, from the view point of the influence of dye-structure on (-ΔF) value.
1) In the interaction between dyes and esters, (-ΔF) values are not concerned with the number and the state of amino-group, and show constant values depending only on esters.
It means that anthraquinone makes an important contribution to the interaction, that X is anthraquinone itself and that α-CH…X-Dye type hydrogen bonding can be written over again to α-CH…A. Q. -S type hydrogen bonding. (A. Q.; anthraquinone, S; substituent)
2) In similar manner to esters, the interaction between dyes and amines can be interpreted only when X is anthraquinone itself.
3) In the interaction between dyes and phenols, (-ΔF) values depend on the dye-structures, and the dependence suggests that an important contribution can be ascribed to α-CH…X-Dye type hydrogen bonding.
In this case, a distinct answer on X can not be obtained, but it does not contradict α-CH…A. Q. -S tyde hydrogen bonding.
4) (-F) values of the interaction between anthraquinone and ester and phenol are nearly equal to those of dyes, and it means that X is anthraquinone itself.
5) From the results 1)_??_4), it is concluded that α-CH…A. Q. -S type hydrogen bonding makes a good part of contribution to disperse dyeing.
