Abstract

Device (1) for treating a yarn, comprising a main body (2) axially crossed by a treatment chamber (3) inside which the yarn (F) slides; at least a first side channel (4) in fluid communication with the treatment chamber (3) for the introduction of at least one substance for treating the yarn (F) and at least a second side channel (5) in fluid communication with said chamber (3) for the introduction of compressed air. The device (1) can be inserted within a system (11) for treating the yarn (F). The system (11) comprises at least one conduit (6) for supplying the device with the substance to be used for the treatment, a conduit (13) for introducing compressed air into the device (1) and a discharge conduit (12) for exiting the air and any fibre possibly detached from the yarn (F). The method of treating the yarn provides for the application within the device (1) and under a controlled vacuum condition of one or more substances onto a yarn through a continuous treatment able to controllably apply such substances on the yarn by subsequently introducing the same yarn directly into a heat-stabilization apparatus located outside the device (1) and having the function of fixing the substances on the same yarn.
