A Review on Recent developments of contaminants detection methodology systems

Textile Technology

Cotton is one of the most widely used and comfortable fibre for textile and apparel. Among the different parameters that determine the quality of cotton, cotton contamination is one key factor that also determines its price. Contamination is "the presence of extraneous and undesirable substance in yarn which leads to impure the quality of final textile product". According to recent survey by ITMF, Indian cottons are amongst the most contaminated cottons in the world due to the lack of availability of systematic instruments to judge the level of contamination. Contaminations present in the fabric not only deteriorate the quality and appearance of fabric, but also affect on the profits of the organization. This chapter includes what cotton contamination is and constitutes, the origins and kinds of cotton contaminants, effects of contaminants on cotton processing, and the different methods used to detect cotton contaminants. Cotton contamination is that the presence of an impurity, or another undesirable component that spoils, corrupts, infects, makes unfit, or makes inferior a product. Therefore, detecting and eliminating cotton contaminations as timely as possible before processing or within the process is essential. The different techniques of detecting contaminants are discussed in detail. The methods used for detecting cotton contaminations are generally classified as manual, gravimetric, electro-optical, and machine vision methods.
