Description

[Detailed Description of the Invention] This invention relates to an apparatus for continuously mercerizing a long fabric while running it.

A mercerization process for a fabric in which a long fabric is impregnated with an aqueous solution of caustic soda while running, and the fabric is strained and washed with water to impart luster to the fabric and improve its dyeability and strength. As a device, a chain type is known. This chain-type mercerization processing device has a first padder, a first tension cylinder group, a second padder, a second tension cylinder group, a mercerizing tenter, and a washer arranged in this order, and the first padder applies a caustic soda aqueous solution to the fabric. After the fabric is impregnated and stretched in the warp direction using a first tension cylinder group, the fabric is again impregnated with the caustic soda aqueous solution using a second tension cylinder group, and stretched again in the warp direction using a second tension cylinder group. Thereafter, the fabric is stabilized by being stretched in the lateral direction with a mercerizing tenter and washed with a shower of washing water, and then thoroughly washed with a washer.

However, in addition to the mercerizing tenter, the chain-type mercerizing processing device described above requires two sets of tension cylinders and two groups of tension cylinders each consisting of 30 or more tension cylinders, which requires a large amount of equipment cost and a large space. It had the disadvantage of being necessary.

This invention eliminates the need for pads and tension cylinders, and enables mercerization while running the fabric with a pin tenter.

That is, in this invention, a plurality of widthwise long caustic soda liquid shower devices and a plurality of widthwise long wash water shower devices are arranged in order in the fabric running direction above the fabric running surface of the pin tenter. At the same time, a suction box for caustic soda liquid and a suction box for washing water, which are in contact with the lower surface of the fabric running surface and are slightly separated from each other in the width direction in correspondence with the above-mentioned caustic soda liquid showering device and washing water showering device, are provided on the respective advance sides. A fabric mercerization processing apparatus, characterized in that suction boxes are arranged in sequence, and an inlet mangle and an outlet mangle are provided in proximity to the fabric inlet and fabric outlet of the pin tenter, respectively, and the circumferential speed thereof is approximately equal to the fabric speed of the pin tenter. be.

In c, the height on the fabric supply side is lowered and the height on the fabric delivery side is increased, and the water receiving tanks 33a, 33b, 33c are
The cleaning water stored in the drain chamber 33d overflows and flows in the opposite direction to the running direction of the fabric F, and is drained from the drain chamber 33d. The washing water shower device 20a at the forefront and the bottom of the second water receiving tank 33b from the front are connected by a water pipe 34a, and a regulating valve 35a and a water pump 36a are interposed in the water pipe 34a, respectively. The shower device 20b for washing water and the third water tank 33

A regulating valve 35c is interposed in this water supply pipe 37.

In the above structure, the fabric F in a dry state is automatically corrected for its deviation by the cross guider 3, and in the spread state passes through the guide rollers 4, 4 and is transferred to the water tank 6.
The fabric F is immersed in water containing a penetrating agent, impregnated with water to improve the permeability of the caustic soda solution, strongly nipped at the inlet mangle 8, fed to the pin tenter 1 via guide rollers 9, The ears are locked by brush rollers 12 to pins of the pinch chain (not shown). Next, the fabric F is conveyed in a spread state by the pinch avenue, removed from the pinch avenue by the guide roller 13 on the opposite side, passes through the guide roller 15, the dancer roller 16, the guide roller 17, and the exit mangle 18, and is sent to the next process. sent to.

On the other hand, the caustic soda aqueous solution stored in the caustic soda liquid receiving tank 27 is sprayed onto the upper surface of the fabric F from the upper caustic soda shower devices 19a and 19b through the liquid supply pipe 28, and this caustic soda aqueous solution is conveyed together with the fabric F. During this period, it permeates into the fabric F and causes the suction boxes 21a and 21 for the caustic soda solution to
The suction pipe 23 passes through the fabric F due to the suction action of the suction box 21a, 21b.
It is circulated to the receiving tank 27 through the channels a and 23b. As a result, the fabric F is treated with the caustic soda aqueous solution, a strong shrinkage force is generated in the fabric F, tension is generated in the warp direction and the width direction at the same time, and mercerization is performed. After this is repeated according to the number of caustic soda liquid shower devices 19a, 19b, the washing water shower devices 20a, 20
Cleaning is repeated by the cleansing water spouted from b, 20c and the suction action of the cleansing water suction boxes 22a, 22b, 22c. The fresh wash water spouted from the wash water shower device 20c at the rear end is used for the final washing, and then is transferred to the water receiving tank 33c at the rear end by the action of the suction box 22c for wash water at the rear end. The washing water collected in this water receiving tank 33 is used for the second washing and then collected in the second water receiving tank 33b, and the washing water collected in this second water receiving tank 33b is After being used for one wash, it is collected in the first water receiving tank 33a and drained without being used for washing.

Therefore, the above pin tenter 1 is provided with an inlet mangle 8 and an outlet mangle 18 close to the inlet and the outlet, respectively, and these strongly nip the fabric F so that the circumferential speed is approximately equal to the speed of the fabric F in the pin tenter 1. Since the fabric F is conveyed while being rotated by the pin tenter 1 while being held by the pins of the pinch chain, a strong tension is generated in the fabric F and the fabric F is not bent. In addition, since the mercerization process is performed by holding the fabric F with a pinch chain, the holding portion of the fabric F is more evenly distributed than in a clip chain, and therefore the shrinkage force is more uniformly distributed compared to a clip chain. Mercerization processing can be performed evenly.

In the above embodiment, if the fabric F supplied from the previous process is in a wet state, there is no need to immerse the fabric F in water in the water tank 6, and the fabric F can be immediately supplied to the inlet mangle 8 from the upper guide roller 4. can. In addition, the caustic soda liquid shower device 19a, 1
9b and the suction boxes 21a, 21b, or the washing water shower devices 20a, 20b, 20c and the suction boxes 22a, 22b, 22c, each need only be two or more, and the number depends on the type of fabric F and the desired processing speed. It is set accordingly. Moreover, it goes without saying that warm water can be used as the washing water.

As explained above, this invention is a method in which the fabric is treated by applying an aqueous solution of caustic soda to the fabric on the pin tenters provided at the inlet mangle and the outlet mangle, and then washed with water. By preventing the fabric from being overfed when it is fastened to the pin chain, a strong tension is generated in the fabric not only in the width direction but also in the length direction.
Furthermore, the mercerizing process can be carried out smoothly without causing any distortion of the weave, and there is no need for padders or tension cylinders as in the past.
Equipment costs and space are significantly reduced.
