Abstract

The book is destined for the people working with cotton, mostly in the spinning mill, but not only. It can be also very useful for cotton classers, ttaders and so on. In the introduction there are described shortly information about cotton growing and classification, evolution of cotton measurement methods on the example of length parameter and short information about cotton fiber properties, which should be measured for a complex quality assessment. The important parameters are: length, length uniformity, short fiber content, strength and strain, color and impurities like trash, dust, neps, seed coat neps, fineness and maturity. Then there are described modem systems for cotton fiber assessment, like High Volume Instrument (HVD, Advanced Fiber Information System (AFIS), FiberLab system, Quickspin measuring the basie properties and thermodetectors measuring the cotton stickiness. Such systems like HVI or FiberLab measure the cotton parameters by the bundle method; whereas AFIS measures the properties of single fibers and then on this basis the statistical analysis is performed. In chapters 2 - 6 there are information how the systems are built, what are the measurement principles, and what parameters describing the given property are applied. In chapter 7 the Author presents the results of comparative analysis conceming different fiber properties obtained by diff erent measurement methods, like length, short fiber content, fineness and maturity, cotton contamination strength and stickiness. In chapter 8 there are presented information about cotton color measurements; whereas in chapter 9 - the newest trends and directions of evolution in cotton quality evaluation. The last two chapters present how the values of particular cotton parameters can be used in the engineeręd way for blend composing, or to predict some properties of cotton yams, or to assess the correctness of the technological process. The book is a good source of information about equipment used actually in the cotton world industry.
