A measuring device for measuring the fineness and maturity of cotton fibers is provided. The measuring device includes a measuring chamber; a supply conduit; a flow regulator arranged along the supply conduit; a first pressure sensor upstream of the flow regulator; a second pressure sensor downstream of the flow regulator; an electronic proportional pressure regulator for regulating the air pressure in the supply conduit; and an electronic processing and control unit programmed to control the electronic proportional pressure regulator as a function of the detections of the first sensor and of the second sensor or of the second sensor alternatively and respectively to keep the difference between the air pressure upstream and downstream of the flow regulator or the air pressure entering the measuring chamber substantially constant and equal to a predeterminable value.

Disclosed are fibers which contain identification fibers. The identification fibers can contain a plurality of distinct features, or taggants, which vary among the fibers and/or along the length of the identification fibers, tow band, or yarn. The disclosed embodiments also relate to the method for making the fibers. Characterization of the fibers can include identifying distinct features, combinations of distinct features, and number of fibers with various combinations of distinct features and correlating the distinct features to supply chain information. The supply chain information can be used to track the fibers, fiber band, or yarn from manufacturing through intermediaries, conversion to final product, and/or the consumer.

Disclosed are fibers comprising one or more branded fibers which exhibit surface markings in a repeated pattern along the length of the branded fibers. The branded fibers can be incorporated into yarns or fiber bands to represent supply chain information of the yarns, fiber bands, and/or articles made from the yards or fiber bands. In a specific example, branded fibers can be incorporated into an acetate tow band The branded fibers can be recovered from a cigarette filter, the repeated pattern decoded, and supply chain information associated with the acetate tow used to make the cigarette filter, such as manufacturer, customer, ship to location, and even the acetate tow bale, can be obtained.

A preparation device prepares a sample of textile fibers, in particular cotton fibers, applicable to analysis and/or measuring apparatuses respectively for analyzing and/or measuring characteristics of the textile fibers forming the sample. The preparation device includes a comb body that can be coupled in a sliding manner along a rectilinear guide that faces a perforated plate against which to press a mass of textile fibers forming protuberances projecting from the holes of the perforated plate. The comb body is arranged to grip tufts of textile fibers from such protuberances. The preparation device also includes at least one brush that is mounted in a sliding manner along a rectilinear guide facing the perforated plate and that is arranged to brush the textile fibers forming the protuberances before the comb body grips the tufts.

Disclosed are fibers which contain identification fibers. The identification fibers can comprise one or more chemical markers, or taggants, which may vary among the fibers or be incorporated throughout all of the fibers. The disclosure also relates to the method for making and characterizing the fibers. Characterization of the fibers can include identifying chemical markers and correlating the chemical markers and a taggant chemical marker amounts of at least one of the chemical markers to manufacturer-specific taggants to determine supply chain information. The supply chain information can be used to track the fibers from manufacturing through intermediaries, conversion to final product, and/or the consumer.

Techniques involve a machine system for producing or treating synthetic threads, comprising a plurality of machine components, having actuators and/or sensors, that are associated with a plurality of control components. The control components are connected by a machine network to a central machine control station. In order to remedy process disruptions as quickly as possible and to ensure uniform product quality, the control components are coupled in parallel to a central analysis station by an analysis network.
