Abstract
Installation for the continuous treatment of at least one textile yarn comprising means for continuously winding at least one yarn picked up on a reel, a deposit head for depositing this yarn on a conveyor belt, at least one thermal treatment enclosure area through which the yarn passes resting freely on the conveyor belt and means for taking up the yarn on the conveyor belt for rewinding it, wherein the thermal treatment enclosure area comprises a yarn drying apparatus using micro-wave or high frequency treatment, and forced ventilation means across the yarn and the conveyor belt.
Claims10
An installation for the continuous treatment of at least one textile yarn, comprising means for continuously moving at least one yarn taken off of a reel, a deposit head for depositing this yarn on a gas permeable conveyor belt, at least one thermotreatment enclosure traversed by the yarn resting freely on the conveyor belt, and an apparatus for taking up the yarn on the conveyor belt for rewinding it, said thermotreatment enclosure comprising an apparatus for drying the yarn by micro-wave treatment or high-frequencies provided with means for forced ventilation across the deposit of yarn and the conveyor belt, wherein said thermotreatment enclosure comprises a fixation zone provided with a tubular sheath which surrounds the conveyor belt and the yarn deposited thereon, this sheath having a double wall made up of a material permeable to the high frequencies or micro-waves utilized and enclosed in this double wall is a circuit of heating fluid, and a drying zone situated downstream of the fixation zone, and wherein the fixation zone and the drying zone are equipped with high-frequency or microwave generators.
A continuous drying process of textile yarns resting freely on a gas permeable conveyor belt, which comprises circulating said conveyor supporting the yarns across a washing or dyeing container maintained substantially at atmospheric pressure, exposing the yarns to microwaves or high frequencies causing a heating of the water contained in the yarns, while performing forced ventilation across the yarns and the conveyor belt, and wherein, in an initial zone of the path of the conveyor belt in the enclosure for heating the yarns, one suppresses the forced ventilation and one maintains an elevated humidity level around the yarns by means of a micro-wave or high frequencies permeable heated sheath, surrounding the conveyor and the yarns supported by it.
