Textiles have always been one of the essential materials for people and have a great variety of uses such as in clothing, agriculture, medical, automotive and aerospace applications. The sort of properties needed for any type of fabric basically depend on the structure of the fibre surface. Of many geometric attributes that can be used to describe the surface appearance of a fibre, yarn, or fabric sample, one of the more common is lustre. Mohair and wool fibre surface structure have been studied using optical microscopy and Atomic Force Microscopy (AFM). Optical microscopy was also used to take fibre diameter measurements. Another technique, goniophotometry, was used to make quantitative lustre measurements of mohair and wool fibres. The surface structure of mohair has got a faint pattern of scales where the scales are generally unpronounced or flat and relatively long. Wool has got a scaly surface structure where the scales overlap leading to interlocking of fibres. The scale configuration on the surface of mohair and wool fibres also differs. A qualitative connection between fibre lustre and the fibre surface structure was found. Because of its smooth surface relative to that of wool, mohair reflects a greater amount of incident light specularly whereas wool reflects most of the incident light diffusely. In general, mohair fibres have a higher lustre than wool due to its less prominent cuticle structure found on its surface. Furthermore, mohair fibres with the smallest diameters give an even higher lustre.

The research question addressed in this study is "what outerwear fabric types are preferred by consumer segments in each of the major climatic zones in Australia?" objectives are to:1. examine consumer preference for fabric in each of the five major climatic zones in Australia, using fabric attribute levels as the choice criteria, in order to provide information to Stormboy on fabric attributes most preferred by consumers, and the market segments in each zone, based on these fabric attribute preferences; and2. determine any significant differences in fabric preference between the climatic zones so as to indicate to Stormboy whether climate should be taken into consideration in the marketing of wool based fabric.This information on preference for fabric type, will enable Stormboy design wool based fabrics that match the fabric attribute requirement of consumers. The information on market segments will not only provide the fabric attribute requirements but also the possible size of the market.This study will develop a method to monitor consumer trends in fabric preference so that Stormboy can make informed decisions about their design and choice of wool based fabric.This study provides the required consumer information to Stormboy. It illustrates a method of research which can be used in decisions making by producers of products or services where there is heterogeneity in buyers' preferences, for:the development of new products or services;the renewal of a product or service;the positioning of a product or service; andthe ongoing monitoring of consumer preferences and retail compatibility with consumer preferences.As Green and Kreiger (1985) conclude, once preference and segments have been identified companies can react to (or possibly produce to) preference heterogeneity by modifications of their current product/service attributes (including price), distribution, and ++ / advertising/promotion. Companies are motivated to do so if the net payoff from modifying their offerings exceeds what the payoff would be without such modification. Companies may modify its product/marketing mix to include product line addition/deletion decisions as well as the repositioning of current offerings.The study begins by reviewing relevant literature on the function of clothing and fabric type, the position of wool in the apparel market, the effect of climate on choice, the key concepts of consumer behaviour and segmentation as a means of positioning products. The design of the research is summarised in Chapter 3, and the findings from a survey of consumers in five Australian centres are presented in Chapter 4. Chapter 5 discusses the implications of these findings and recommendations made to StormBoy. Conclusions relating to the study design, limitations and future research are addressed in Chapter 6.
