It is not surprising that the various regions developed their own systems of textile measurement and textile vocabulary. In a world in which the pace of life was relatively slow, regional variations in systems of units were tolerable, but to-day communications are rapid, and commerce and technology need a uniform system of measurement that is universally accepted and understood. Errors of conversion are automatically eliminated, but, of course, during the transitional stage, there will be misunderstandings and arithmetical errors when old units are converted into new, even when prepared conversion tables are used. For textile calculations, it may be found that the usual sets of conversion tables do not include quantities peculiar to the textile industry. For these quantities, a conversion system has to be devised by using first principles and then published as a table or graph or left just as a conversion factor. Most of the calculations made by a textile technologist consist of a series of relatively simple steps, mainly arithmetical and at times using elementary aspects of trigonometry, geometry Algebra. The calculation is generally straightforward; it is the local thinking required that often presents most difficulty. It is usually worth spending a few minutes in considering various approaches to a problem before setting down the first line of calculation. An engineer or research scientist may employ more complex mathematics, a thorough training in pure and applied mathematics being required. The objective of any experiment or measurement should be to produce an answer that is as accurate as the instruments available and the skill of operator will allow. For many calculations, the person doing the necessary numerical work has a rough idea of the order of magnitude he should obtain. Scientific sampling, design of experiments, the analysis, presentation and interpretation of data through statistical techniques-all these created the concept of specification, production and inspection as a dynamic cycle. Inspection now is the source of data which, analyzed and interpreted through statistical methods, is continuously feed back to production people for corrective and preventive action. Inspection, that is, the act of screening out defectives before they reached the customer.
