Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes a heated gas or fluid to introduce thermally conductive multifilament yarn into a crimping chamber.

The present invention relates to the texturing of thermoplastic multifilaments in which the threads are folded together in a crimping chamber to form a packing of crimped threads. The crimping chamber is usually formed with a vent so that the gas, i.e. the yarn entering the crimping chamber, is forced towards the filling area and then exits to the outside through the vent. It is now possible to do so. The filling body is pushed through the crimping chamber by the continuous formation of the yarn of the filling body, and thus the crimped yarn is pulled out from part a of the filling body on the side opposite to the supply side. It turns out. While the thread is being pulled out while the filling layer is in the crimping chamber, or before the round yarn is crimped and being pulled out from the crimping chamber, the filling body is pushed and protrudes from the crimping chamber immediately in front of the crimping chamber. Occurs during a period of time.

A ninth method of controlling the length of the charging rod has been used. ? In the case of IJ, the degree of supply and delivery of the thread to the filling body or the degree of withdrawal of the thread from the filling body may be changed depending on the length of the 14 bodies. State of the art also provides for the temperature of the gas, R#-, which advances the yarn through the device ft to be varied according to the length of the light field or the speed of the packing moving through the crimping chamber.

Preferably, an expansion chamber is provided between the yarn supply channel and the crimp chamber. This allows a pressurized region or gas filling the yarn to rapidly expand laterally as the yarn advances.

As a result, - the yarn is made bulkier by increasing its cross-section; When this bulked round thread Fi is pushed through the discharge passage connecting the expansion chamber to the crimping chamber, it is tightened again. smaller than the cross-sectional area.

A device made and recommended by this method is disclosed in British Patent Publication No. 1.344.
．． It is disclosed in the specification of No. 484.

As a result of the yarn being opened by the expanding scum or fluid and being pressed against the edge of the inlet of the restricted passage between the expansion chamber and the crimping chamber, the yarn is at the bottom of said light J4#-. Since the yarn can be folded together, some of the plurality of single filaments constituting the yarn will be individually crimped to some extent before the yarn is crimped as a whole. The individual winding of a plurality of single filaments increases as the threads are forced around the walls of the nine expansion chambers that meet the outlet of the supply passage.

The textured processing device of the present invention has a British Special Publication No. 1!
Textured equipment of the type disclosed in No. 1,342.484 #11. That is, it is configured to include a yarn supply passage, a nine expansion chamber equipped with a discharge port, a yarn discharge passage and a crimping chamber, and the yarn supply passage is connected to the expansion chamber,
The pressurized gas or R-body expands laterally within the expansion chamber, i.e. radially perpendicular to the direction of yarn travel, increasing the yarn shear E1it-.

Then, the yarn enters the #ll base yarn discharge passage leading to the expansion chamber, and its cross section is reduced again until it reaches the crimp chamber.

A thermoplastic multifilament yarn texturing device is used in which the yarn is mutually folded vhK under pressure in a crimping chamber, and three or more 11iI11iiK lateral passages extending in the lateral direction are provided in the texturing device, and the crimping When the yarn enters the yarn discharge passage leading to the contraction chamber and the cross section of the yarn is reduced, a plurality of single filaments constituting the yarn are pressed into the transverse passage by expansion of the f-body, that is, the waste. This increases the crimp of the yarn. Providing two diametrically identical transverse passages is Ai1
It is disclosed in Figure 4 of the British Patent Publication No. 4 mentioned above.

In such a cedar shape, the expanded bundle of single filaments is only maintained in a relatively tight and narrow side cedar shape.

Increasing the number of lateral passages from 2 to 3 increases the crimp, and increasing the number of lateral passages from 2 to 3 increases the number of lateral passages, such as 5, for example, 6.
If the number is 7 or more, the crimp will be significantly increased.

A plurality of separation members are provided between adjacent lateral passages and separate the vicinity of the outlet of the yarn supply passage of the expansion chamber into individual lateral passages, such as wall-shaped or column-shaped separation members. is applied to multiple single filaments that make up the yarn.
, ~ It is preferable to have sharp corners with gs edges that can give a declino effect. When a plurality of single filaments are pressed against a directional marriage path, a plurality of single filaments are rubbed against one surface of a plurality of separation members or the Li2 number increases, thereby individually nipping the single filaments into a large number of single filaments. This causes a clicking sound, which helps to increase the overall size of the pongee.

An embodiment of the present invention flit will be described in detail with reference to the accompanying drawing rkU.

As shown in Figure 1, a filament yarn 2 is fed into a yarn feed channel 4 of a duplexing device, generally indicated at 6, by means not shown.

High pressure steam or gas is supplied from a source through a temperature control device (not shown) into the channel 8 and from the channel 8 to the yarn supply passage 4.

Upon leaving the yarn supply channel t', the yarn is opened into single filaments or groups of several single filaments by the rapid expansion of the steam in the JIl extension 10. A steam outlet 12 is provided that allows for both chambers 1oK#1I114. - The plurality of spun filaments in good condition are placed on the dome-shaped ceiling wall 1 of the expansion chamber 10.
4 a nine pieces, then gathered together and made into a thread again 9
．． The yarn is pushed through the yarn discharge passage 16 and into the crimp chamber IB.

Thread company N! They are mutually folded and crimped by the braid 18 to form four light bodies 2B made of round threads. A mating portion 22 that opens into a jacket 24 is provided below the mat 18 at 20 .

The upper part of the Textured D Loe device is not shown, but is substantially identical to the device shown in Figure 1 of the previously cited British Patent No. 1.342.484.

The upper part of the textured BrJ device is described in the British Patent Specification. The mounting position of the processing device is by no means unstable, and the entire device may be used upside down or placed in a horizontal position. In this case, an appropriate suppressing means - 1 is provided inside the device facing the exit of the device and engaged with the brake of the manning staff to prevent the light horizontal bar from protruding outside the device. You can prevent this from happening.

Features of the present invention The cedar-like shape of the Sakaki structure inside the room 1O. A yarn supply passage 4 is formed in the insert member 36, and the insert member 3612) Ja#i section is formed by a number of circumferentially spaced columns 32, and the columns 32 laterally This state in which the directional passage 34 is formed is #! This is best shown in FIGS. 2 and 3. Figures 2 and 3 are plan views of two embodiments of the push-in member 36. Note that the insertion member 36 of the embodiment shown in Fig. 2 is inserted into No. 1 #4.
0 cross-sectional views are shown.

When the yarn 2 reaches the end of the yarn supply passage 4, a rapid and controlled expansion of steam occurs which causes the single filaments of the yarn 2 to radially separate and then separate from the single filaments. It bulges outward through the transverse passageway 34. The plurality of columnar bodies 32 are provided with sharp corners, and as the plurality of single filaments bulge, they are rubbed against one or several of the corners of the plurality of columnar bodies 32. . A considerable portion of the plurality of single filaments will then be individually edge-ringed.

In addition, the plurality of single filaments are brought into contact with the ceiling wall 14 of the expansion chamber and are also compressed by the yarn discharge passage 2.
By engaging and rubbing against the edge S of the entrance to 6, its crimp will be increased.

In the device of the present invention, a relatively large number of radial lateral passages (such as those shown in FIGS. 3
(8 pieces of it in the figure) are provided. This causes the steam to expand outwards, so that the yarn is opened into groups of many single filaments.

This results in fewer single filaments within a group of single filaments. A considerable portion of the single filament is then rubbed one by one.

As a friend, the degree of crimp in textured yarn as a metal bar will be greatly improved.
