Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heat treatment device for heat setting a fabric.

[0002]

[Prior Art]

 Conventionally, as an interior material for automobiles, a wrinkled polyvinyl chloride sheet and a polyurethane sponge are integrally laminated. In recent years, however, the trend toward lighter weight, lower cost, and fiberization has been increasing, and tricot raised products obtained by raising the surface of a knitted fabric have been favored. As a method for producing this tricot napped product, a method is known in which the knitted fabric is french napped to produce naps, heat treated, and then dyed and shuffled.

However, when the French raising is performed, a partial yarn breakage may occur in the filament yarn constituting the knitted fabric, and when the raised faces come into contact with each other due to loading of the knitted fabric into the carrier or the like. However, a part of the broken filament yarn enters the other loop, and a yarn entangled state (so-called fastener phenomenon) occurs. When heat setting is performed in this yarn entangled state, there is a problem that the filament yarn cut due to thermal contraction pushes other loops, resulting in a defect in the recess.

In order to prevent this drawback, raising hair after dyeing has been studied, but there is a problem that a step of applying a raising agent is necessary and the number of times raising hair is increased, so that work efficiency is not improved. At present, however, it is general to repair the above-mentioned concave defects by manual work in the final inspection process, and such work is inefficient, and it has been desired to solve the problem.

[0005]

[Problems to be solved by the device]

 The inventors of the present invention have conducted earnest research on a device that can prevent the filament yarn cut by the French raised hair from being entangled with other loops, and as a result, have found a heat treatment device for a fabric that solves the problems of the existing method. Heading The present invention has been completed.

An object of the present invention is to provide a heat treatment apparatus for a fabric, which can prevent the filament yarn cut by the French raised fibers from being entangled with other loops before the heat treatment.

[0007]

[Means for Solving the Problems]

 For the above-mentioned purpose, the cloth is transferred in the chamber while being spread by the tenter, and in the heat treatment apparatus for the cloth in which hot air is blown to the cloth, the cloth is brought into contact with the cloth in front of the entrance of the tenter. In addition, a heat treatment device for the fabric is provided, which is provided with a brushing roll that positively rotates in the opposite direction to the running of the fabric.

[0008]

[Action]

 Since the present invention is configured as described above, the brushing roll provided in front of the tenter inlet can be used to loosen the yarn entangled state in which a part of the filament yarn cut by the French raised hair enters the other loop. The filament yarn cut by the heat shrinkage of the subsequent heat treatment does not press other loops and the recess defect does not occur.

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments.

FIG. 1 is a side view showing a schematic configuration of a heat treatment apparatus for fabrics, which is an inlet apparatus (I), a spreading section (T), a heat treatment chamber (N), and an outlet (not shown). And a device.

The inlet device (I) has a cloth carrier (5) on which a cloth (4) made by raising a knitted cloth is distributed and placed, and a cloth (4) taken out from the cloth carrier (5). The guide rolls (6), (7), and (8) that guide the (T), the swivel tension (9) that adjusts the tension of the fabric (4), and the running path of the fabric (4) do not shift. The brushing in which pig hair is planted on the surface which contacts the cross guider (10) and the cloth (4) which is the core of the present invention and which is positively rotated by a motor (not shown) in the direction opposite to the running direction of the cloth (4). It consists of rolls (3) (see Figure 2).

Further, the spreading section (T) includes a plurality of guide rolls (11), (12), (13) for guiding the cloth (4) and a first overfeed roll for giving an overfeed to the cloth (4). (14) and the second overfeed roll (15), and the tenter (1) which grips both ears of the cloth (4), spreads it in the width direction, and transfers it.

The heat treatment chamber (N) is composed of a branch duct (16) for blowing out hot air sent from a hot air circulation device (not shown) and a chamber (2) for preventing hot air from escaping.

Next, the operating conditions of the fabric heat treatment apparatus configured as described above will be described.

First, the cloth (4) placed on the cloth carrier (5) is adjusted with the swivel tension through the guide rolls (6), (7), (8), and the brushing roll is used. In (3), the yarn is entangled and fed to the spreading section (T). The fabric (4) supplied to the spreading section (T) is fed with the overfeed amount via the guide rolls (11), (12) and (13) to the first overfeed roll (14) and the second overfeed. It is supplied to the tenter (1) while being adjusted by the roll (15). The cloth (4) supplied to the tenter (1) is subjected to heat treatment by being blown with hot air in the chamber (2) while being expanded, and sent out to the outlet device.

Next, specific examples will be described.

Example 1 Polyethylene terephthalate 75d / 36f semi-dal filament was used as a front yarn and a back yarn, and a herringbone tricot fabric was knitted by a 28-gauge tricot knitting machine. However, the combination of the design of the front yarn and the back yarn was in order, and the number of courses was 65 threads / inch.

The front side of the obtained knitted fabric was napped four times by a nap cloth raising machine having a pile roller No. 32 / counter roller No. 34 woven cloth.

Next, using the heat treatment machine shown in FIG. 1, after brushing with a brushing roll, heat setting was performed at 185 ° C. for 60 seconds. After that, the heat-set knitted fabric was dyed with a high-pressure jet dyeing machine at 130 ° C. for 60 minutes using a disperse dye, and then dried at 170 ° C. for 60 seconds using a heat treatment machine shown in FIG. Then, the dyed knitted fabric was shuffled by a shearing machine and resin-finished to obtain a tricot raised fabric of Example 1.

Comparative Example 1 The same herringbone tricot material as in Example 1 was used, and the same treatment as in Example 1 was carried out except that the brushing roll in the process of Example 1 was not used. I got the goods.

The product according to Example 1 did not have a recess defect due to yarn entanglement, and the product according to Comparative Example 1 had a recess defect due to yarn entanglement.

Although pig hair is used for the brushing roll in the embodiments, it goes without saying that a palm, a piano wire, a stainless wire, a nylon thread, a cloth-like etiquette brush, or the like may be used. Although the peripheral speed of the brushing roll is not particularly limited, it is preferably higher than the transfer speed of the cloth.

[0023]

[Effect of the Invention] As described in detail above, according to the present invention, the filament brush cut by the French raised hair is prevented from being entangled with other loops by the brushing roll at the entrance of the tenter. The filament yarn is heat-set without being entangled with other loops, so that a defective recess does not occur and productivity and quality are improved.
