THE STANDARD FROM FIBER TO FABRIC 4 (20) USTER ® PRODUCTS
THE STANDARD FROM FIBER TO FABRIC 1 Introduction After the harvest, a producer wants the optimum yield possible and the spinner wants the highest quality fiber available. The ginner is asked to make both happen. Cotton ginning is an important step in the cotton production sequence. The purpose of the ginning operation is separating the cotton seed from the lint and removing sticks and coarse trash from the input material. Input materials coming from a variety of growing areas are processed together and the process acts as a first blending of massive quantities of fibers [1]. The true art of ginning is knowing when and how to use a technical advantage. Because not all cottons are the same, the ginning process requires constant monitoring based on incoming harvest qualities, fiber characteristics, picking methods and growing conditions. The USTER ® INTELLIGIN-M monitors and/or controls the ginning process through a system of online sampling stations located throughout the gin from the module feeder to the bale press. Information on fiber moisture, trash and color are fed into a main console where software analyzes fiber value for optimum dryer temperature and lint cleaning practices. Optional bypass valves automatically reroute cotton only through necessary equipment preserving fiber quality and reducing processing costs. From an easyto-use console, the ginner has a complete picture of all variables and can manually adjust the process or set perimeters to allow the process to run automatically. The USTER ® INTELLIGIN-M provides total quality control of the ginning process. 2 The total quality control of the ginning process 2.1 What is the function of a cotton gin The principal function of the cotton gin is to separate lint from seed. The gin must also be equipped to remove foreign matter, moisture, and other contaminants that significantly reduce the value of the ginned lint. Gins (Fig. 1) must produce a quality of lint that brings the owner of the cotton maximum value while meeting the demands of the spinner and consumer. Cotton seed is an important by-product of cotton manufacture and most of the seed is crushed for oil or used for animal feed. According to the yarn producer, cotton seed represents hazard and excessive seed-coat fragments make the spinning process more difficult. USTER ® PRODUCTS 5 (20)
