Abstract: A device measuring the fineness and/or maturity of cotton fibers contains a measuring chamber accommodating a cotton fiber sample and a tubular plunger. The measuring chamber extends between a first end closed by a wall having one or more vent holes and a second end opposed to the first end and hermetically closed. The plunger penetrates within the measuring chamber through the second end to run at least two strokes of predetermined lengths and has an inner channel extending between a tail portion and a perforated head portion placing the inner channel in fluid communication with the measuring chamber. The device further contains a reservoir placed upstream of the inner channel and in fluid communication with the inner channel; a pump filling the reservoir with air from an environment; and a flow regulator placed downstream of the reservoir and upstream of the inner channel.

Abstract: A method for measuring the moisture content, the length and at least one dynamometric characteristic of textile fibers, includes pressing a layer of textile fibers between a pair of plates parallel to one another, withdrawing a line of textile fibers from said layer thus pressed and making the textile fibers of said line substantially coplanar and parallel to one another, bringing said line of textile fibers to a measuring area at which at least to perform one measuring step, moving the textile fibers away from the measuring area after having performed the at least one measuring step and measuring the moisture content of the textile fibers by means of microwave sensors.

Abstract: A measuring device for measuring stickiness, imperfections and impurities in textile fibers, such a device includes a housing inside which a pair of rollers are placed, arranged side by side to one another and rotating in opposite senses and between which a web of cotton fibers is made to pass. The rollers are heated, the sticky fractions of the web that adhere to the rollers after the passage of the web between them are detected, and the sticky fractions adhering to the rollers are removed, wherein the heating is controlled by a processing and control unit as a function of the temperature of the rollers detected by a temperature sensor associated with them.

Abstract: The present invention relates to a method for measuring the moisture content, the length and at least one dynamometric characteristic of textile fibers, in particular, cotton fibers, comprising the steps of: pressing a layer of textile fibers between a pair of plates parallel to one another, withdrawing a line of textile fibers from said layer thus pressed and making the textile fibers of said line substantially coplanar and parallel to one another, bringing said line of textile fibers to a measuring area at which at least to perform one measuring step selected from measuring the length and at least one dynamometric characteristic of the textile fibers forming the line, moving the textile fibers of the line of textile fibers away from the measuring area after having performed the at least one measuring step and measuring the moisture content of the textile fibers forming the layer and/or forming the line of textile fibers, by means of microwave sensors for measuring moisture, wherein said step f) of measuring

Abstract: The present, invention refer(c) to. a measuring device (200) for measuring stickiness, imperfections and imparities in textile fibers, in particular cotton fibers, such a device comprising a housing inside which. a pair of rollers (203a, 203b) are placed, arranged side by side to one another and rotating in opposite senses and between which a web of cotton fibers is made to pass, heating means for heating the rollers (203a, 203b) , detection means (205a, 205b) for detecting the IS sticky fractions of the web that adhere to the rollers after the passage of the web between them, removal means (206a, 205b) for removing from the rollers (203a, 203b) the sticky fractions adhering thereto, wherein the operation of the heating means is controlled by a processing and control unit as a function of the temperature of the rollers detected by temperature sensor means (207a, 207b) associated with them.
