Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a process for producing a polyester-acetate pulsar interaced yarn,

The present invention relates to a process for producing a polyester-acetate pulverulent interlaboratory work and a product thereof.

Since the 1980s, the appearance of new synthetic fibers has resulted in the qualitative growth of synthetic fibers. Recently, however, as consumers' demands have diversified, individualized, and advanced, there has been a need to develop materials capable of expressing high sensitivity and functionality, such as aesthetics and comfort The domestic textile industry has been pointed out as a major problem in the deterioration of the management conditions due to the increase in raw material costs and labor costs, and the deterioration of competitiveness due to the pursuit of quality of foreign late companies and low price offensive. In addition, the flammable industry is in a state of losing its competitiveness mainly due to the fact that its own technology development capability is insufficient, and the development and investment of differentiating material yarns for the competitiveness and profitability in the textile field, As well.

In addition, research has been actively carried out to achieve a variety of functionalities and fashionability that can not be expressed by a single material by combining heterogeneous materials. However, it has been developed to such a degree that there is no limit to the technique of material differentiation. However, · The technology of compounding is limited in terms of productivity and economics, and its development has reached a mere level.

In response to the demands of the times, human's emotions tend to be more natural, while the preference of natural color, which is represented by various colors together with solid tone, leads to the continuation of melange effect processors and fabrics Consumer demand. However, until now, melange tone materials have been produced in a great number of times, but the process of mixing different materials in the manufacturing process has a limitation, so that only a regular color combination can not be achieved.

In order to manifest a natural melange effect which is not regular, a irregular interlace yarns manufacturing device is used to produce a random melange according to the difference in dyeing of various materials such as cellulose fiber / synthetic fiber / CDP ) Was developed to utilize the developed yarns to develop the random rain melange effect. The Random rain melange effect was maximized by using the developed yarns. It is a trend to develop differentiated fabrics that develop various structures and express various functionalities and feel through salt processing.

Thus, in Korean Patent No. 10-0483591, the fibers in the two groups are entangled with each other in the air entraining unit after the S / Z simultaneous smoke is applied to the fibers in the opposite direction to each other, and the air injected into the air entrainer is regularly or irregularly The present invention provides a method for simultaneous manufacturing of an isoflavone composite pullover fabric, which is characterized in that air is entangled while interrupting the production of pulp of the same kind of synthetic fibers having similar physical properties, And it is not possible to propose a condition for the manufacturing of the waste mixed complexes.

Therefore, according to the present invention, there is a difference in physical properties by overcoming the problems of the prior art in the prior art, and it is possible to use a polyester filament and acetate filament, which show a large difference in dyeing, It is a technical problem to provide a construction work of a molten iron which can obtain a fabric having a variety of appearance including a soft lane melange effect because it can express a jade tea with a color.

Therefore, according to the present invention, the polyester yarn is supplied to the first feed roller, passed through a heater to be thermally treated, fed to the S / Z combustor to perform a false operation, and the acetate yarn is bypassed to the S / Z combustor And then supplied to the second feed roller. Then, polyester yarn and acetate yarn are supplied to an air entangling machine having a nozzle diameter of 1.2 to 1.8 mm and an air pressure of 0.5 to 2.0 kg / cm < 2 & A method for producing a polyester-acetate pulverulent interlaboratory work is provided, characterized in that air entanglement is effected while regularly supplying and blocking the jet.

Hereinafter, the present invention will be described in more detail.

The raw material fiber used in the production method of the polyester-acetate pulverulent interlabial work of the present invention is a filament, and the polyester has a tensile strength of 3.0 to 5.0 gf / d and an elongation of 20 to 50%, and an acetate yarn has a strength of 1.0 to 2.0 gf / d, and 20-30% of the elongation, and it is a heterogeneous filament showing a large difference in dyeing. Therefore, polyester yarn among the above-mentioned different kinds of fibers is supplied to the S / Z combustor and is combusted, and the acetate yarn bypasses the S / Z combustor to manufacture a composite construction. In air entraining, air entraining is regularly supplied and blocked, The air pressure and the supply and cut-off ratios are important in this case.

First, the above-mentioned raw material fibers are compounded as many as necessary, and the polyester yarn in the two yarns of polyester yarn and acetate yarn is fed to the S / Z stirrer before the air entangling step so that the yarn inside the S / Torsion can be applied by two adjacent belts. Acetate does not become flammable due to cellulose fiber, so it must be bypassed and compounded.

1, the polyester yarn 1 is supplied to the first feed roller 3, passed through the heater 4, heat-treated, fed to the S / Z combustor 5 to perform a false-twist operation, The yarn 2 is bypassed without supplying to the S / Z combustor 5 and fed to the second feed roller 6, and then the polyester yarn and the acetate yarn are fed together to the air collator 7, Thereby causing air entanglement. The polyester yarn has an overfeed rate of 0.98 to 1.8, an angle of 80 to 120 deg. Between the inner disc and the belt, a VR of 1.1 to 1.60 as a ratio between the belt and yarn, and a heater temperature of 160 to 210 deg. It is good for expressing the effect. The over feed rate of acetate is preferably about 0.99 to 1.1.

When the twisted polyester fiber is discharged from the S / Z combustor, the inside of each fiber becomes flammable and coarse, and becomes unleaded. However, since there is no kite in the acetate fiber, So that the residual torque of the motor is canceled. In particular, polyester yarns and acetate yarns have characteristics of an isosurface composite yarn due to their fiber properties, and they have a complex character of polyester easy care, a refreshing feeling of acetate, a deep coloring property and excellent human affinity.

Then, the mixed fibers of the two groups of fibers discharged from the S / Z combustor are simultaneously supplied to the air entraining unit to produce interlocking work. At this time, in the entangling process, As the yarn rotates and revolves, the raw material fibers are entangled with each other, and they can be manufactured as a yarn having shape stability by having a certain shape and strength of yarn due to such action.

In the conventional method for producing an entangled yarn, heterogeneous fiber bundles are entangled individually and the entangled yarn is doubled by an additional twist yarn process. However, in the present invention, You can interject. The reason why the heterogeneous fiber bundles are not entangled together in the conventional entangling process is that there is a difference in the properties of the individual fibers, so that it is difficult for the processing conditions to proceed to the integral process. If the same conditions are satisfied, And the like. However, in the present invention, the combination of the S / Z misalignment mechanism and the bypassing step enables the twisting and collapsing without changing the physical properties between the different kinds of fibers.

In the air entraining mechanism of the present invention, the air injected by the nozzles is repeatedly interrupted by automatic control to cause air entrainment while regularly supplying and shutting off air injections. When the air is cut off, the fibers do not become entangled and do not collapse, resulting in bulky yarns. When the air is supplied, the fibers are tangled due to the airflow, A collusion history can be obtained. As the air interruption time increases, the length of the bulky portion increases and the length of the bulky portion decreases as the air interruption time becomes shorter.

In the present invention, in consideration of the physical properties of the polyester and the acetate fiber, the supply time of the air spray is 0.05 to 2.0 seconds, and the blocking time is irregularly supplied and blocked at intervals of 0.025 to 0.10 seconds, Melange effect can be expressed. Particularly, when the air shutoff time is extremely short and less than 0.025 second, even if the air is shut off, the bulky smoke may not be produced because the air pressure remaining in the valve continues to be interrupted, so that the shutoff time should be appropriately adjusted as described above .

The air entraining mechanism of the present invention preferably has a nozzle diameter of 1.2 to 1.8 mm and an air pressure of 1.0 to 2.0 kg / cm 2. When the air pressure is less than 1.0 kg / cm 2, there is a problem that the melange effect due to non- / Cm < 2 >, there may be a problem of cost increase due to excessive air supply and deterioration of properties due to infiltration of the yarn.

By repeating the supply and shutoff operation of the air, it is possible to manufacture a high-collision-type bridge construction in which the interlocking portion and the comparative locking portion are alternately formed. By controlling the supply time and the interruption time of the air injection, Is adjusted.

In the case of dying a fabric applied with interlocking construction obtained by intertwining heterogeneous fibers as described above, the entangled portions to which air is supplied are homogeneously mixed, and the dyed portion and the un-dyed portion are homogeneously mixed, The polyester part is separated into a dark state and the acetate part is un-dyed. When the woven fabric is woven with an interlocking construction as shown in FIG. 2, a plurality of colors It is mixed and divided into a hypochromic part and a hyperchromic part depending on the staining color. Depending on the length of the entangled part and the material appearing on the surface, a melange tone material having various colors may appear. Particularly, unlike the entanglement of the same kind of fibers, the unusual phenomenon can exhibit a difference in shade in the same color, so that a fabric having various appearance including light rain melange effect can be obtained.

The spacing between the interlocking portion and the comparative locking portion may be regularly formed to form a uniform pattern by the dyeing difference at the time of weaving. In addition, if the false twist is additionally performed after the jamming, the degree of flammability of the overlap portion and the comparative jamming portion changes, and the rain melange effect due to the dyeing effect can be further improved.

Therefore, according to the present invention, by using polyester and acetate filaments, which are different from each other in dyeing, it is possible to have a certain shape and strength and to have shape stability and to have a pulsating property according to the degree of flammability It is possible to provide a construction work for the McDonalds interchange, and it is possible to present a jade car with the same color, so that it is possible to provide the construction of the McDonalds interchange which can obtain the fabric having various appearance including the lane melange effect.
