Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woven cloth processing apparatus and a processing method for applying antibacterial processing, antiallergic processing, etc. to a surface of a woven cloth such as a cloth wound in a roll.

[0002]

2. Description of the Related Art Conventionally, the method of subjecting a woven cloth to antibacterial treatment has been to immerse the cloth in an antibacterial agent tank in the state before dyeing or softening and squeeze and dry. The fiber or cloth thus treated with antibacterial treatment is then finished into clothes or the like, further treated with a softening agent, and then subjected to a predetermined finish before being shipped.

[0003]

In the case of the above-mentioned conventional technique, the woven cloth is once dipped in the antibacterial agent tank, squeezed and dried, so that the processing apparatus becomes large in size, and it takes a considerable time to dry the cloth, resulting in a high efficiency. It was not good. Also, in order to shorten the drying time, the drying temperature must be raised,
In addition to requiring a large amount of energy, the heat for drying may change the fibers and the antibacterial agent. Further, in the case of a woven fabric having long naps, when it is dipped in a chemical solution and then dried, fine long fibers adhere to each other or the fibers become hard.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides a woven cloth processing apparatus and a processing method capable of easily and surely processing a woven cloth with a desired chemical. The purpose is to do.

A pipe 26 connected to a steam generation boiler (not shown) is connected to the injection nozzle 24. Further, exhaust ducts 23 and 25 are provided above the belts 10 of the first and second steam injection devices 14 and 18, respectively.

A chemical spraying device 16 is disposed between the first and second vapor injection devices 14 and 18, and spraying nozzles 28 and 29 are provided on the front surface side and the back surface side of the belt 10, respectively. The spraying nozzles 28 and 29 are provided so as to be able to spray the medicine over the entire width of the belt 10 by a swing mechanism (not shown). The drug spray nozzles 28 and 29 are provided with a drug tank 3 that stores a drug under pressure via a pipe 30.
Connected to 2.

A suction device 20 connected to a pump or the like (not shown) is arranged adjacent to the second steam injection device 18 in the traveling direction of the belt 10. Suction unit 33 of the suction device 20
Are provided almost all over the width of the belt 10 and are provided so as to be suckable over the entire width of the belt 10.

A drying device 21 is arranged adjacent to the suction device 20. The drying device 21 has a heater unit 36 and a blower 38, a drying chamber 37 is provided so as to surround the belt 10, and hot air is circulated. The temperature of the hot air is optimally in the range of 110 ° C to 140 ° C and about 130 ° C.

A woven fabric feeding section 11 is provided at the base end of the belt conveyor 12, and a woven fabric winding device 22 is provided at the terminal end.
Is installed. In the woven cloth feeding section 11, the woven cloth 40 is pulled out from the cloth winding roll 42 together with the belt 10 and sent out. The feeding speed is set so that the moving speeds of the woven fabric 40 and the belt 10 become equal.
Similarly, in the woven fabric winding device 22, the dried woven fabric 40
Is wound around the winding roll 43 while applying a predetermined tension.

The operation and operation of the woven fabric processing apparatus of this embodiment will be described below. First, the belt conveyor 12 is operated to put the end portion of the woven fabric 40 on the belt 10 of the woven fabric feeding section 11. Then, the woven fabric 40 is placed at a predetermined position on the belt 10.
Woven fabric 40 together with the belt 10 by fixing the ends of the
The leading end of the sheet is sent to the end of the belt conveyor 12. Then, the end portion of the woven cloth 40 is wound around the winding roll 43 so that it can be continuously wound. As a result, thereafter, the antibacterial treatment or the like can be performed while continuously sending out the woven fabric 40.

In the antibacterial treatment of this embodiment, the woven fabric 40 on the belt 10 and the belt 10 together with the first steam injection device 1
4, and steam is injected from above and below. At this time, since the belt 10 is in the shape of a net, steam is sufficiently jetted to the back surface side of the woven cloth 40. The steam is a high temperature steam of about 100 ° C to 140 ° C.

Further, as the belt 10 moves, the woven cloth 40 is sent to the drug spraying device 16 and the drug is sprayed from above and below. The drug sprayed here is, for example, urethane resin fine particles (microcapsules) impregnated with mugwort extract or hinokitiol having antibacterial and antiatopic properties,
It is a mixture with a binder in a solvent.

The sprayed chemicals are soaked into the woven cloth 40 easily because sufficient steam is jetted to the woven cloth 40 and moderate moisture and high temperature steam are present in the woven cloth 40. After this, the woven fabric 40 is further sent to the second steam injection device 18,
The sprayed drug is more evenly distributed in the woven cloth 40. Then, the woven cloth 40 is sent to the suction device 20, and the excess medicine, vapor, and water are suctioned and removed.

Thereafter, the woven cloth 40 together with the belt 10 is
The water and solvent components are sent to the drying chamber 37 of the drying device 21 to evaporate, and as shown in FIG.
And the binder component 45 adheres to the fiber 46 and remains. In this way, the fine drug particles 44 firmly adhered to the fibers of the woven fabric 40 are surely left on the fibers 46 together with the binder component 45, as shown in FIG. 3, even when the washing test according to JIS is repeated 20 times. There is something. Here, FIG. 2 and FIG.
Is a sketch of an electron micrograph in which the fibers of the woven fabric 40 are magnified 2350 times.

According to the woven fabric treating apparatus and the treating method of this embodiment, the chemicals can be evenly and reliably sprayed on the woven fabric, and the desired antibacterial effect and the like can be achieved. In particular, since the woven cloth 40 is not soaked in the liquid, the woven cloth 40 is easily dried, and furthermore, the mist of the chemical is surely soaked into the fibers of the woven cloth 40 by the steam, and the chemical spraying effect is also high. Further, since the woven cloth is not soaked in the chemical solution, the woven cloth with long naps is in a good finished state and does not become hard.

In the woven fabric processing apparatus of the present invention, the steam injection apparatus may be arranged on only one side, and the drying method of the drying apparatus may be drying by blowing air or natural drying.
In addition to the belt of the belt conveyor,
The woven cloth may be sequentially transferred by a transfer means other than the belt. In addition to the antibacterial agent, other softening agents, UV-cutting agents, surface treatment agents such as silk fine particles, and the like can be arbitrarily selected as the agents to be sprayed.

[0021]

According to the woven fabric treating apparatus and the treating method of the present invention, the desired chemical is surely dispersed on the fibers of the woven cloth, and the chemical is surely soaked into the inside of the woven cloth. Moreover, since the woven cloth is not soaked in the liquid, the drying time is short, the drying energy is small, and the finished state is good. Further, the desired treatment of the woven fabric can be performed very efficiently by simply placing the woven fabric on the conveying member, and the woven fabric of a small lot can be easily treated.
