Embodiment Construction

[0052] Embodiments of the invention are described with the aid of a heat exchanger, which is used as a cooler in the texturing process of synthetic yarns, wherein the yarn to be treated passes through it at very high speeds, e.g. at running speeds above 2000 m / min cooler. It requires a high cooling effect, such as cooling the yarn from about 200°C to about 50°C in a short period of time. Water in direct contact with the yarn is used as coolant. The sealing device 2 is filled with air. Of course, other heat exchange media or sealants can also be used for the heat exchanger used in the corresponding process and for the corresponding purpose. The heat exchanger described with the aid of an exemplary embodiment for processing synthetic yarns can also be used without problems for processing textile panels or films.

[0053] figure 1 The heat exchanger shown as a cooler has a base body 6 and a cover plate 60 . The heat exchanger is detachable, that is, the yarn running on the b...

Abstract

The invention relates to a method and device for continuously treating synthetic fibers in a heat exchange chamber, in which the fiber to be treated comes into direct contact with the heat exchange medium. A sealing device, which is subjected to the action of a sealing medium, is provided at the fiber exit opening and at the fiber entry opening with a supply line for the sealing medium, which is arranged in the proximity of the fiber exit opening or the fiber entry opening. The sealing medium is kept away from the fiber passing through the heat exchange chamber. This is achieved by removing the sealing medium before the heat exchange chamber or also by removing a cooling medium together with the sealing medium. In addition, the heat exchanger is provided in a separable manner so that the fiber can be inserted by removing one part.

Description

technical field [0001] The invention relates to a method and a device for the continuous treatment of synthetic yarns in a heat exchange chamber, wherein the yarn to be treated is in direct contact with the heat exchange medium, the heat exchange chamber having a yarn inlet and a yarn outlet, between the yarn inlet and Sealing devices filled with sealing medium are arranged on the yarn outlet respectively, and the sealing device has a sealing medium input channel close to the output yarn or the input yarn. Background technique [0002] EP0624208B1 discloses such a device. The heat exchanger is first used as a heating device and then as a cooling device. In each case, the primary heated fluid and the primary cooled fluid are in direct contact with the yarn. For this purpose, its fluid is located in a heat exchange chamber through which its fluid flows. The heat exchange chamber is substantially tubular and has small holes at its ends through which the yarns pass and are dr...
