Experimental results of the Slub memory composite processing yarn as shown in Table 4 show that the optimum state is achieved at a heater temperature of 120 ° C., a core yarn speed increase of 20%, and an effect yarn speed increase of 35%.

As a result, in the case of the change in cutting strength and elongation due to the increase of the overfeed rate of the effect yarn, the strength and elongation decrease with the increase of the overfeed rate. It is easy to form and is formed too large, and it reduces the stability of composite machining and reduces cutting strength.

Therefore, in the case of 10% overfeed rate of the core yarn, the overfeed rate of 20% of the effect yarn did not significantly affect the strength and elongation.In the case of 20% of the core feed yarn, the overfeed rate of the effect yarn was 35%. It can be seen that does not significantly affect the strength and elongation at.

That is, it is preferable that the overfeed rate of the effect yarn is larger than the overfeed rate of the core yarn.

In conclusion, in the present invention, the yarn speed fed to the feed roller is discharged at 300m / min under optimum conditions, and the core yarn flowing into the air nozzle is increased by 10% to 20% of the yarn yarn, and introduced into the air nozzle. Increase the speed of the effect yarn to 20% to 35% of the yarn speed, but the overfeed rate of the effect yarn is 75% to 100% greater than the overfeed rate of the core yarn, and the air nozzle pressure is 10kg / cm ² . Pulverized yarn and effect yarn are discharged and heat processing of composite processing is performed by heating the temperature of 120 ℃.

If the size of the firing speed is greater than or less than 300 m / min, the heat treatment effect is lowered by the heater. If the pressure of the air nozzle is less than 10 kg / cm ² , the filament of the effect yarn and the core yarn is reduced, and the pressure of the air nozzle is reduced. Larger than 10 kg / cm ² will cause damage to the filament of the effect yarn and core yarn.

Therefore, considering the post-processing workability under the above conditions, it can be said to be the optimal condition because it is possible to produce a machining effect, quality uniformity, thermal stability, and natural touch.

On the other hand the present invention provides a wrinkle recovery fabric that is woven by using the composite workpiece in any one or more of the weft and warp.

In other words, the composite yarn may be used as a weft yarn, and the known memory yarn may be inclined, the composite yarn may be inclined, the known memory yarn may be used as weft yarn, or the composite yarn may be inclined with the weft yarn.

For example, in the present embodiment, the composite fabrics manufactured by various methods were used as weft yarns, and the fabrics were woven with various known memory yarns as inclined yarns to measure the fastness, wrinkle recovery, stretchability, and feel of the fabrics.

(Fastness and rate of dimensional change)

As a result of measuring the fastness and dimensional change rate of the composite processing, it can be seen that washing, friction, and consistency are almost the 3rd to 4th grade or higher as shown in Table 5, which is higher in terms of the fastness compared to the fabrics fabricated with conventional memory yarns. There is no problem.

In addition, in the dimensional change rate, it can be seen that it is within the quality performance indicator range of ± 3% at the level of 0% to 1%.
