摘要:
A process for conditioning a yarn package (1) enclosed within a conditioning chamber (21) by introducing low temperature steam at approximately 140 degrees F for two seconds, thereby setting the twist of the yarn after spinning and winding.
摘要:
An oxidation intensifier device for a continuous dyeing system for dyeing a warp thread, the device arranged for being mounted in the oxidation assembly of the dyeing system and comprises two blowing assemblies having a substantially identical shape and opposed one another, each blowing assembly is provided with at least one respective fan and, downstream of such a fan, with a respective plurality of convergent conduits arranged along development directions that are parallel and transversal to the feeding direction of the warp thread, the convergent conduits of a first blowing assembly converge in a opposite direction with respect to the convergence direction of the convergent conduits of the opposite blowing assembly, each convergent conduit is configured to face parallel to a single lap of the warp thread moving inside the dyeing system and is provided with a plurality of longitudinal slots oriented along the same development direction of the respective convergent conduit, where each fan is hydraulically connected to the plurality of convergent conduits of the respective blowing assembly and is configured to convey air towards the plurality of longitudinal slots, so that a plurality of opposite air laminar flows is generated, which generate a plurality of turbulences adapted to facilitate the oxidation process of the dyed warp thread on both its surfaces.
摘要:
Die Erfindung betrifft ein Verfahren zur kontinuierlichen Bearbeitung eines fadenförmigen Gutes mit mehreren Verfahrensschritten sowie eine Vorrichtung zur Durchführung des Verfahrens. Erfindungsgemäß sind eine Liefereinrichtung (10), eine Behandlungs- (35) und Ablagevorrichtung (36), eine Transportvorrichtung (14), eine Thermofixiereinrichtung (32) sowie eine Längenausgleichseinrichtung (37) in einem gemeinsamen abgeschlossenen System (5) angeordnet und das abgeschlossene System (5) unterscheidet sich in seinem Inneren durch mindestens eine erste physikalische Eigenschaft von der Umgebung und innerhalb des Systems (5) sind für die verschiedenen Verfahrensschritte gegeneinander abgeschirmte Untersysteme (31, 32, 33, 35, 36, 37) vorhanden, an die Versorgungseinrichtungen (25, 26, 27) angeschlossen sind, die als zweite physikalische Eigenschaft zumindest teilweise unterschiedliche Temperaturen in den Untersystemen (31, 32, 33, 35, 36, 37) erzeugen.
摘要:
The invention concerns a method for producing non-wovens during which a cellulose carbamate solution is spun by means of extrusion through a nozzle block having a number of openings into a precipitation bath to form a number of endless threads and, afterwards, is mingled by subjecting it to a flow of a gaseous medium and/or fluid. The invention also concerns a non-woven of the aforementioned type and the use thereof.
摘要:
The invention is directed to a process for depositing additives into a yarn having multi-filaments comprising steps of; separating the multi-filaments of the yarn into individual filaments while winding the yarn; injecting the additive onto the individual filaments; and promoting the individual filaments of the yarn to close up one against the other whereby the additive are entrapped within the multi-filaments. The invention also concerns an apparatus for depositing microcapsules into a multi-filaments of a yarn and the multifilament yarn produced.
摘要:
A plant for the production of staple or tow material is described, comprising a dyeing station (2), a centrifuge station (3) and a drying station (44). Said plant further comprises a loading station (1) comprising means (18-25) able to pour the material into a basket (5), to press the material into the basket (5) and to operate a lid (8) separably associable with the basket (5), and a discharge station (4), located downstream of said dyeing station (2) and of said centrifuge station (3), comprising means (36, 41-43) able to disengage the lid (8) from the basket (5) and to remove the material from the basket (5).
