【Background technique】

The texturing process of textile silk is to use heating and stretching to make the textile silk have a certain degree of elasticity. This kind of tow is more commonly used in the field of socks and other clothing. In the texturing process, the heating part is a relatively important link. , and the temperature control and humidity control in the heating process are also very critical.

If the method of electric heating is only used, the humidity will not be enough. This state of "dry" heating and "dry" stretching will eventually lead to the problem of poor elasticity of the textile yarn and easy to break, and if it is an electric heating method, the temperature needs to be strictly controlled. If it exceeds 150°, it will have a great impact The properties of textile yarn, if the temperature is too low, the effect of stretching and elastication will not be achieved; and if it is simply heated by steam, it will lead to excessive humidity, excessive elasticity after stretching and retraction, and excessive elasticity.

Heating device 2:

As shown in Figures 5 to 7, in this embodiment, the heating device 2 includes a hollow wire tube 21, through which the chemical fiber filament 40 or precursor passes through the wire tube 21 for heating, and the inside of the wire tube 21 can pass through One chemical fiber filament 40 can also pass through multiple chemical filaments at the same time. In this embodiment, it is preferred to pass through multiple chemical filaments in a wire feeding tube 21, and the heating device 2 includes feeding tube 21 An electric heater 22 for heating, the heating device 2 also includes a steam pipeline 23, the chemical fiber yarn 40 is located between the steam pipeline 23 and the inner wall of the wire feeding pipe 21, and the steam pipeline 23 runs along the chemical fiber yarn 40 Steam outlets 231 are arranged at intervals in the filament direction, and steam is passed into the steam pipe 23 and discharged from the steam outlet 231 to heat the chemical fiber filaments 40 .

The heating device 2 in this embodiment includes two methods of electric heating and steam heating, wherein the electric heater 22 heats the wire feeding tube 21 itself, and the steam heating mainly uses the steam in the steam pipe 23 to give the chemical fiber 40 Heating, which has the advantages of rapid heating of electric heating, and also solves the problem of insufficient humidity of electric heating, and also solves the problem of excessive humidity when steam heating alone, allowing the humidity to reach a more suitable range. Therefore, the elasticity of the chemical fiber filament 40 is moderate.

In addition, in this embodiment, electric heating and steam heating are structurally optimized. First, the electric heater 22 directly heats the wire feeding pipe 21, while the chemical fiber filament 40 is directly arranged in the wire feeding pipe 21, that is, the electric heater The heat generated by 22 heating is basically directly transferred to the chemical fiber filament 40, there is no barrier in the middle except steam, and the heat loss is relatively small;

For steam heating, since steam is directly passed into the steam pipe 23 and directly discharged from the steam outlet 231 to heat the chemical fiber filament 40, there is no barrier in the middle, that is, the steam is discharged to the chemical fiber filament 40 from the steam pipe 23. In the middle, the heat loss is also small, and the steam pipe 23 itself is inside the wire pipe 21, and the wire pipe itself has a thermal insulation effect, so the steam basically does not lose heat in the steam pipe 23;

At the same time, the shape of the wire passing plate 24 in this embodiment is circular, which just matches the inner wall of the wire tube 21. Therefore, the steam pipe 23 and the wire-passing plate 24 are arranged as a whole, which is equivalent to the effect that the wire-passing plate 24 has played a role in positioning the steam pipe 23.

In this embodiment, the shape of the steam outlet 231 is also preferably set. Since a plurality of chemical fiber filaments 40 are passed through in a wire feeding tube 21 in this embodiment, a strip-shaped slit is provided on the steam pipe 23 to form the The steam outlet 231 forms a fan-shaped injection area when the steam is ejected from the slit, and the plurality of chemical fiber filaments 40 are located in the fan-shaped injection area.

There are thread passing holes 241 on the two thread passing plates 24, and the chemical fiber filament 40 will not jump up and down excessively in the thread passing holes 241, thereby playing a stabilizing effect.

In order to further improve the stabilizing effect, a partition 25 is arranged inside the stable cavity 201, and the partition 25 divides the stable cavity 201 into an upper cavity 202 and a lower cavity 203, and the chemical fiber filament 40 passes through the upper cavity Cavity 202, one side of the lower cavity 203 is used to feed steam, and the other side communicates with the steam pipe 23, the side where the steam is fed is provided with a steam inlet 2031, the upper cavity 202 and the lower cavity 203 are separated from each other, and the upper cavity The cavity 202 will not be affected by the steam flow, and the lower cavity 203 is preferably a closed space, one side of which is fed with steam, and the steam enters the steam pipe 23 after being temporarily stored in the lower cavity 203, and an airtight lower space is set. The effect of the cavity 203 is to make the lower cavity 203 a space for stabilizing the pressure, so that the steam can be continuously and stably input into the steam pipeline 23 without interruption.

For the electric heater 22, there can be multiple implementations. For example, the electric heater 22 can be a separate heating wire 221, and the heating wire 221 is directly distributed on the outer wall of the wire feeding tube 21 at intervals in the circumferential direction or wound around it. On the outer wall of the wire pipe 21, the wire pipe 21 is directly heated; or, the electric heater 22 is an electric heating tube, and of course a corresponding heating wire 221 is also arranged on the electric heating tube, and the electric heating tube is inserted Installed in the wire feeding tube 21, the steam pipe 23 is built in the electric heating tube, the latter is used in this embodiment, and the advantage of using the latter is that the electric heating tube is also detachable, which is more convenient for maintenance and cleaning .
