Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a solution for fabrics using highly twisted yarns, which aims to untwist the highly twisted yarns and generate fine wrinkles throughout the fabric in knitted and woven fabrics using highly twisted yarns. The present invention relates to a twisting processing method and an apparatus thereof.

600~ per meter for twisted yarn for weaving and knitting fabrics
The fabric has 2,500 twists, and by untwisting, that is, untwisting the woven or knitted yarn using this twisted yarn, it is possible to make the fabric have a fresh texture.

Traditionally, this type of fabric is processed by wrapping it around a frame (creape-like processing), and then tightening the edges of the fabric to prevent it from unraveling. A number of unit bodies made of
Furthermore, this drum is rotated within the sealed batch, and by rotating the drum, the moist heat temperature within the batch is increased over time while applying an impact to the winding unit of the fabric. The temperature is 1
When the temperature reaches nearly 00°C, the temperature inside the batch is lowered to about 40°C, during which it is slowly cooled, and then the batch is opened, and the fabric is taken out from the drum and wrung to obtain a fabric. Met.

In such a conventional wringing method, workability is poor because it requires a step of winding a predetermined length of fabric around a frame.

b. Because the threads were tied after the fabric was wound around the frame, the flow of the grains or the grains were poor.

Since the processing of C0 fabric is done in a discontinuous manner, mass production has been lacking.

d. Since the batch must be opened every time the fabric is replaced within the batch, the moist heat within the batch completely escapes, resulting in wasted thermal energy.

e. It is not possible to keep the moist heat temperature within the batch constant each time the fabric is replaced within the batch, so each fabric is unevenly distributed.

There were drawbacks such as.

In order to eliminate such drawbacks, the present inventor first transferred the fabric to be processed continuously, and during this transfer, the fabric was subjected to a moist heat temperature of 70°C to 100°C in stages. The authors have proposed a method of applying an impact to the fabric during the action of moist heat to untwist the fabric's weaving and knitting yarns to create wrinkles. As a result, by sequentially performing temporary untwisting at normal pressure and temperature, followed by secondary untwisting using dust at high pressure and internal temperature, the occurrence of mottled wrinkles and rough wrinkles can be prevented, and uniform and high quality grains can be achieved over the entire surface of the fabric. We discovered that it is possible to cause

In other words, primary untwisting at normal pressure and internal temperature means that the temperature of the sprayed liquid applied to the processed fabric is adjusted from around 70°C to 100°C while the processed fabric is transferred in a meandering manner without tension by upper and lower net conveyors that are separated from each other. The force of hitting the fabric with the jet pressure of the liquid while raising it step by step until it gets close,
It is to apply massaging force.

In addition, secondary untwisting is a process similar to the above-mentioned untwisting using a high-temperature jetted liquid of 100°C to 150°C. It has the advantage of being able to produce fine, high-quality graining uniformly and continuously over the entire surface of the fabric.

The present invention will be explained in detail below based on embodiments shown in the drawings.

1 is a normal pressure moist heat treatment chamber;
Inside is a nozzle that injects a fluid, for example, a liquid or a mixed fluid of liquid and gas, at high pressure into the gap a formed by the two vertically spaced endless net conveyors 2 and 2'. These nozzles 3 are arranged in a vertical staggered manner in the transport direction of the net conveyor 2°21.

Reference numerals 40 and 4□ are liquid receiving tanks arranged at the inner bottom of the moist heat treatment chamber 1, and inside these liquid receiving tanks 4□ and 42, steam blowing pipes 6 for heating the liquids 5□ and 5□ and the liquids are installed. A temperature regulator 7 is provided to adjust the temperature, and for example, the liquid temperature in the liquid receiving tank 4□ is set to about 70°C, and the liquid temperature in the liquid receiving tank 42 is set to about 85°C.
It has been adjusted so that

The liquid in the liquid receiving tank 41 is pumped by a pump (not shown) to each nozzle 3 located above the liquid receiving tank 4, and the liquid in the liquid receiving tank 42 is transferred to the liquid receiving tank 42, which is located above the liquid receiving tank 42. The water is ejected from each nozzle 3 under strong pressure.

Further, a fabric inlet 10 and a fabric outlet 11 are provided.
An inlet-side seal mechanism 12 and an outlet-side seal mechanism 1 are provided in each of the
3 is provided.

These sealing mechanisms are provided to allow the fabric to be introduced and taken out while maintaining the high-pressure moist heat inside the high-pressure moist heat treatment chamber 8. The seal rubber roll 120 has a liquid sealing tank 122 and a throttle bar 123 provided on the inlet 10 side of the seal rubber roll.

The other outlet-side sealing mechanism 13 has a pair of sealing rubber rolls 131 pressed against each other, and an annealing tank 13□ provided on the outlet port 11 side of the sealing rubber rolls.

Net conveyors 140 and 142 are vertically spaced apart inside the high-pressure moist heat treatment chamber 8, and a gap a is formed between the net conveyors 14 and 14□.

And a nozzle 15 that injects heated liquid toward each gap a along each of the net conveyors 141 and 142.
are arranged in a staggered manner.

Reference numeral 16 denotes a liquid tray provided under the lower net conveyor 142, and the liquid, for example 120

Further, the liquid temperature in the liquid sealing tank 122 is heated to around 100°C, and the water temperature in the slow cooling tank 13□ is adjusted to about 50°C.

There, the fabric 9 was transferred to the net conveyor 2 in the normal pressure moist heat treatment chamber 1.
, 21, and is transferred as the net conveyors 2, 2' rotate.

The fabric being sandwiched between the upper and lower net conveyors 2 and 2' is first sprayed with a liquid at about 70°C from the nozzle 3, so that the fabric is transported at the 70°C liquid temperature. While expanding, the jetting force acts on the tapping force and the kneading force, and the untwisting of the fabric knitting yarn begins.

Next, a liquid heated to about 85°C is sprayed onto the fabric from a nozzle, so that it is further swollen and
Untwisting over the entire surface of the fabric gradually progresses due to the beating force and kneading force caused by the jet force.

The fabric that has been primarily untwisted in the normal pressure moist heat treatment chamber 1 is immediately supplied to the high pressure moist heat treatment chamber 8, and in this high pressure moist heat treatment chamber 8, upper and lower net conveyors 14□, 14□
A high-temperature heated liquid of about 130°C is blown from the nozzle 15 onto the fabric transferred without tension between the two, and the swelling and untwisting of the fabric further progresses, resulting in a cloth with the desired wrinkle. be.

The fabric that has been completely untwisted in this way is placed in slow cooling tank 1.
After passing through 3□ and being led out from the high pressure moist heat treatment chamber 8, it is cleaned by a cleaning device 19 and transferred to the next process.

As described above, the present invention is equipped with a normal pressure wet heat treatment chamber and a high pressure wet heat treatment chamber, and first, in the normal pressure wet heat treatment chamber, a heated liquid is heated to a temperature of approximately 70° C. to 100° C. Then, in a high-pressure moist heat treatment chamber, the dough is expanded with a liquid heated to 130'C, and then a beating force and a kneading force are applied. Therefore, the untwisting of the fabric gradually progresses, and there is an effect that the untwisting scallops are uniformly generated over the entire surface of the fabric.

Further, according to the present invention, since the treatment temperature is varied from about 70° C. to 130° C., the quality is good and there is also the effect of producing noticeable grains.
