Conversely, if the tension is kept low to avoid the above risks, at least for the first pass, the yarn will experience instability, vibration and slow wave oscillation due to the tension being too small, resulting in suboptimal performance of the process

Embodiment Construction

[0050] refer to figure 1 , according to the present invention, a kind of device for eliminating hairiness of yarn 11, its whole is marked by reference number 10, is provided with a singeing machine 12 in it, and this singeing machine 12 comprises a generator device 13 for generating energy source 14, It defines a treatment area 15 into which the yarn 11 is transferred and subjected to a dehairing treatment.

[0051] Energy source 14 may be, for example, a flame produced by a gas burner. However, other energy sources may be used instead, such as an energy source capable of producing an electric arc or other sources of energy suitable for the combustion treatment of the yarn, in accordance with the teachings of the present invention.

[0052] Hereinafter, we will mainly describe flames as the above-mentioned non-limiting means.

[0053] Such as figure 1 A kind of embodiment mode shown, yarn 11 is unclamped from reel 16, is controlled by the first sensor of probe 18, and hairi...

Abstract

The method to eliminate fluff from a yarn (11) comprises a first step in which the yarn (11) is made to transit in a processing zone (15) of a singeing machine (12) in which a source of high intensity energy (14) is positioned in order to carry out a first pass of removing the fluff. The method comprises a second step in which the yarn (1 1), exiting from said processing zone (15), is picked up again and diverted in order to be made to transit substantially continuously at least a second time inside the processing zone (15), in proximity to the source of energy (14), in order to carry out a second pass of removing the fluff. The second pass occurs in a direction concordant with the first pass. A control and adjustment is provided of the tension of the yarn (11) in at least one point of the diversion, guide and return path, between the first pass (F1) and the second pass (F2).

Description

technical field [0001] The present invention relates to a device, a method and obtained yarns for dehairing yarns, especially those yarns mainly composed of short fibers including vegetable, animal, man-made or synthetic fibres. Background technique [0002] The known singeing process is to transfer the yarn with unacceptable hairiness to a processing area or a processing chamber and close to an energy source that can provide enough energy to burn off the main body of the yarn. Hairiness formed by protruding fiber ends. [0003] Known singeing techniques are usually managed by adjusting the transfer speed of the yarn close to the energy source, since this is the most easily controllable parameter of equipment design. [0004] There is an inverse proportional relationship between the yarn processing speed and hairiness, the increase of the initial hairiness will bring about a corresponding reduction in the working speed, which has a significant impact on the production effic...
