The process of weight reduction of the textile product (C) using the continuous weight loss machining apparatus of the present invention thus constructed will be described.

The textile product (C) to be processed in the present invention is applicable to yarns or fabrics made of polyester fibers, but also to man-made fibers such as nylon and acrylic fibers other than polyester fibers.

The fiber product C to be subjected to the weight reduction process is passed through the guide rollers 22 and passes through the upper roller 24 and the lower roller 25 located on the immersion tank 21 in a zigzag manner, So that a predetermined amount of the aqueous alkaline solution 23 remains in the fiber product through the pressing rubber roller 26. [

The fiber product C is conveyed to the inlet 33 of the primary heat accumulating chamber 30-1 constituting the heat treatment section 30 via the guide roller 22 and is conveyed to the fiber product C is supplied into the primary metathesis chamber 30-1 maintained at 100 to 125 ° C through the mouthpiece 34 and then passed through the preheating heater 37 and the upper and lower guide rollers 35 and 36 in a zigzag manner And is conveyed to the moving guide roller 42 at the inlet of the connecting pipe 32 connected to the secondary shear chamber 30-2.

The textile product C after the weight reduction process is taken out to the outside through the outlet 44 formed at one side of the secondary steam chamber 30-2. At this time, the water seal device 50 is provided at the outlet 44, And is drawn out to the outside in a completely blocked state with air.

The water tub 50 is filled with the water 50 at the lower end of the outlet 44 and the draw pipe 51 formed at the outlet 44 is located in the water so that the fiber product C drawn to the take- Is conveyed to the water detail 60 via the underwater guide roller 54. The water content is discharged from the secondary shear chamber 30-2 through the water seal device 50 to the water detail 60 So that the weight reduction processing is performed without heat loss inside the secondary shear chamber 30-2.

Particularly, in the case of the conventional weight reduction machining apparatus, the structure is such that after exiting from the outlet of the first metathesis chamber, it flows into the second metathesis chamber again, and then is transferred to the second metathesis chamber through the outlet of the second metathesis chamber. Is exposed to the outside, heat loss is generated at the entrance portion, and the internal temperature is lowered, so that the weight reduction processing, that is, the hydrolysis reaction time is shortened so much.

However, in the present invention, all the remaining portions except the inlet 33 of the first metathesis chamber 30-1 are shielded from the outside, so that little heat loss occurs. Therefore, the second metathesis chamber 30 -2), the reaction time is prolonged and the weight loss effect is increased.

Therefore, when the same weight loss is demanded using the same fiber product (C), conventionally, the concentration and the amount of the aqueous alkaline solution are increased and more heat energy is required for the temperature control, but this problem can be solved in the present invention .

The upper heater 38 and the spray nozzle 39 are installed on the ceiling of the primary metathesis chamber 30-1 and the secondary metathesis chamber 30-2 during the weight reduction process so that the saturated vapor of the positive pressure reduced by the pressure reducing valve The saturated steam is injected continuously through the injection nozzle 39 and the saturated steam is again heated by the upper heater 38. Since the heated steam is lowered to heat the fiber product C, The preheated fiber product (C) is kept at the desired temperature continuously by the heating of the steam to increase the weight loss effect.

The tension guide roller 36 'provided on the lower guide roller 36 maintains a proper tension while lifting and lowering in accordance with the tension of the fiber product C by the tension adjusting means of the displacement detector 40, (C) is softly maintained and the generation of wrinkles due to the exertion force can be suppressed.

The exhaust pipe 454 formed at the lower end of the primary metathesis chamber 30-1 and the secondary metathesis chamber 30-2 is driven by the optimum driving of the exhaust fan 46 driven in conjunction with the temperature sensor 47 provided therein It is possible to prevent heat loss due to excessive exhaustion so that the optimum temperature condition is always satisfied, thereby enabling effective weight reduction.

An auxiliary immersion tank 48 filled with an aqueous alkaline solution may be provided on the lower guide roller 36 of the primary metathesis chamber 30-1 so as to replenish the aqueous alkaline solution, It is possible.

8, the outlet 44 'is formed on the side of the secondary steam room 30-1, as shown in FIG. 8, in the water sealer 50 installed in the outlet 44 of the secondary steam room 30-2. And the fiber product C drawn out by constituting the water seal device 50 on the outlet 44 'is passed through the underwater guide roller 54' located in the water of the water tray 52 ' And the outlet 44 'may be completely blocked by outside air by the separator 56 to prevent heat loss.

The condensation preventing heater 41 formed at the lower end of the inlet 33 of the primary steam chamber 30-1 functions to sufficiently heat the inlet 33 to prevent condensation from occurring at the inlet.

The fiber product after the weight reduction process in the heat treatment section 40 passes through the washing tub 61, the drum washer 62 and the washing tub 61 constituted by the water details 60 to sufficiently wash away the aqueous alkaline solution, And then loaded neatly through the loading section 70.

As described above, the present invention minimizes the heat loss in the heat-treating chamber in the heat treatment unit and allows the treatment time to be prolonged, as well as being able to be treated with a storage power, It is possible to reduce heat energy, solvent, water and the like, and also to increase the merchantability of the textile product subjected to weight reduction.
