It is likely to prove a valuable exercise to create a ‘private collection’ of interesting yarns, and the effect they have on fabric appearances. Clearly, the majority of textile testing and analysis falls outside the Introduction to fancy yarn structures 31 scope of this work, and it is not necessary knowledge for the development of a familiarity with fancy yarns. However, some analysis which is possible without much equipment or expense remains worthwhile as a means of gaining empirical knowledge of yarn structures and properties.
The first ‘scenario’ is therefore xf(target country) for each target country or group of countries. These results, R, which can be described as the ‘extrapolated production figures’, can then be listed and discussed with suitable respondents who can comment on the likely accuracy of the figures and suggest changes to be made to them. 3 offers a reminder of the derivation of R. 3 a possible result of applying this technique to some of the available figures for 2001, using the United Kingdom as the reference country.
