DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a warp sizing machine,
The present invention relates to a method for drying a warp to which a size liquid is attached by a heating cylinder.

[0002]

2. Description of the Related Art In a warp sizing machine for spun yarns, as shown in FIG. 29
And then dried.

[0003] The heating cylinders 23 to 29 have the same dimensions, the diameter of a pipe for supplying steam for heating to the cylinder, and the like, and the same drying ability.

[0004] The angles θ _{1 to} θ _{7 at} which the warp yarns y are wound around the heating cylinders 23 to 29 are as large as possible from the viewpoint of effective use of the heating cylinder, and are about two hundred and several tens degrees. The warp winding angle θ _{1 of the} heating cylinder 23 around which the warp y is wound first and the warp winding angle θ ₇ of the heating cylinder 29 at which the warp y is wound last depend on the arrangement positions of the front guide roller 30 and the rear guide roller 31. Above, slightly smaller than that of the middle heating cylinders 24-28, but more than two hundred degrees.

[0005] The amount of water evaporated from the warp y in the drying section 22 is large, and is usually larger than the weight of the warp y itself.

[0006]

However, in the warp sizing machine as described above, the first heating cylinder in which the warp to which the sizing liquid is attached first winds the largest amount of moisture evaporating from the warp, Most drop in temperature. In the second heating cylinder, in which the warp is wound next to the first heating cylinder,
The amount of water evaporated from the warp is the second largest, and the amount of decrease in the surface temperature is the second largest.

Accordingly, the size liquid of the warp wound around the first heating cylinder becomes dry and increases in tackiness, adheres to the surface of the first heating cylinder to form a film, and then the film is dried. Peel off and adhere to warp.

[0008] The size residue of the film adhered and transferred to the warp is
It is caught and accumulated on the front comb of the winding section, causing large-scale thread breakage.

[0009] In the second heating cylinder, as in the first heating cylinder, there is a case where the size residue of the film is generated and adheres to the warp.

Therefore, in the first heating cylinder or the first heating cylinder and the second heating cylinder, the running speed of the warp, that is, the operating speed of the warp sizing machine, is used to prevent the size liquid from drying out and to prevent the generation of size residue. Can not be fast, 5
0 to 80 m / min.

That is, the warp sizing machine as described above cannot increase the operation speed and cannot increase the work efficiency.

In the first heating cylinder or the first heating cylinder and the second heating cylinder, in order to prevent the generation of size residue, it is conceivable to make the drying capacity of the heating cylinder stronger than the other heating cylinders. However, the equipment cost becomes very expensive and not practical.

An object of the present invention is to solve the above-mentioned conventional problems.

[0014]

SUMMARY OF THE INVENTION The present invention relates to a warp sizing machine for sequentially winding and drying a plurality of heating cylinders on a warp to which a sizing liquid is attached, and a warp winding of a first heating cylinder on which a warp is wound first. The drying method is characterized in that the angle is smaller than the warp winding angle of the second heating cylinder by which the warp winds next to the first heating cylinder by at least 20 degrees, and is set to 60 to 180 degrees.

The warp winding angle of the first heating cylinder around which the warp is wound first is smaller than the warp winding angle of the second heating cylinder at which the warp winds next to the first heating cylinder by at least 20 degrees. The drying method is characterized in that the warp winding angle of the cylinder is smaller than the warp winding angle of the third heating cylinder by which the warp winds next to the second heating cylinder by 20 degrees or more.

[0016]

In the drying method of the present invention, the first heating cylinder or the first heating cylinder and the second heating cylinder are provided with:
Since the warp winding angle is smaller than in the conventional case, the amount of water evaporating from the warp is small and the decrease in surface temperature is small.

[0017]

According to the drying method of the present invention, the first heating cylinder or the first heating cylinder and the second heating cylinder have a smaller surface temperature drop than the conventional case, so that the size liquid is It is difficult to generate glue residue.

Therefore, the warp sizing machine can be operated at a high speed, and the working efficiency can be increased.

In the first heating cylinder, or in the first heating cylinder and the second heating cylinder, it is easier to reduce the warp winding angle than to increase the drying capacity and does not require expensive equipment costs.
