Image Processing as a Tool to Develop High Quality Cotton Fabrics to Get Bigger Profits

M. Lauber, B. Wulfhorst


The assessment of Cotton fabrics is not only based on the description of the feel of the fabric and its elasticity, it is also based to a large extent on the subjective characterisation of the visual appearance of the fabric. Digital image processing can be used for carrying out an objective evaluation of specific features or alterations to features.

Particular significance is attached to the connection between the yarn structure and the visual appearance of the fabric. Two aspects are particularly significant: Digital image processing can be used for ascertaining the specific structural differences between fabrics made from different Cotton fibres. This objective quantification of alterations in features represents the basis for further developing the structure of yarns with the final article in mind. Digital image processing can be used for displaying what effects or possible impact modifications in the fibres may have on the intimate blending of the individual components in the yarn. These studies may contribute towards highlighting difficulties in terms of different dyeing behaviour or in terms of other properties, which are dependent on the homogeneity of the intimate blending.

Aided by digital image processing, the analysis of the visual appearance of the fabric clearly proves that the appearance of the fabric can be changed and it can be designed with the desired article in mind by virtue of the choice of fibre fineness combinations. Digital image processing serves as a tool for describing this varying fabric appearance purposively and, thus, for objectively assisting in the development of the article.
