Abstract

PURPOSE:To prevent the mutual sticking of warps in sizing treatment, without lowering the overall efficiency by sizing warps delivered from a creel to form a beam warp and forming a single weaving beam by drying warps delivered from plural beam warps. CONSTITUTION:A warp delivered from a creel 1 is passed through a sizing machine 2 to form a beam warp B1 and the warps delivered from plural beam warps are dried to form a single weaving beam B3.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application in Industry A) This invention relates to an improvement in a sizing drying method in a warp preparation step.

(Prior Art) In the conventional warp yarn preparation process, warp yarn sizing and drying were generally performed in pairs. For example, warp yarns pulled out from a creel are glued and dried to form one rough winding beam, and warps are pulled out from several rough winding beams prepared in this way to form one loom beam.

There is also a method in which one rough winding beam is formed from the warp threads pulled out from the creel, the warp threads pulled out from this rough winding beam are glued and dried, and one loom beam is formed from several rough winding beams thus prepared. There is also a method in which one rough winding beam is formed from the warp threads pulled out from a creel, and the warp threads pulled out from several rough winding beams prepared in this way are glued and dried to form one loom beam.

By the way, when performing sizing, if the warp density is high, adjacent warp threads will stick to each other, resulting in a loss of quality, so a lower warp density is more advantageous. On the other hand, when performing drying, the higher the speed, the larger the capacity of the dryer is required, so the lower the speed, the more advantageous it is.

Furthermore, since the warping process forms one rough-wound beam from the warp drawn out from the creel, and the beaming process forms one loom beam from a plurality of rough-wound beams, it is inevitable that The warving process is
Compared to the beaming process, the warp density is lower and the process is faster.
In addition, the beaming process has a lower warp density and is operated at a lower speed than the warping process.

Now, in the case of conventional methods 1 and 2, since the sizing and drying is done in a warping process with a small warp density, there is no problem in terms of adhesion during sizing, and it is possible to reduce the drying speed. However, since there is a limit to increasing the capacity of the dryer, the gluing speed is regulated by the drying speed, which has the disadvantage that the overall efficiency is hindered. In the case of the third method, there is no problem in terms of the capacity of the dryer because the sizing is dried in a slow beaming process, but
Since sizing is performed with a high warp density, the problem of mutual adhesion arises.

In this way, when pasting and drying were performed in pairs within one process, it was not possible to improve both the overall efficiency and quality.

(Summary of the Invention) An object of the present invention is to avoid mutual adhesion of warp yarns during sizing without impeding overall efficiency and without increasing the size of the dryer.

Therefore, in the present invention, warps from a creel are glued to form a rough winding beam in the weaving process, and warps from a plurality of rough winding beams are dried to form one loom beam in the beaming process. This is a summary.

(Embodiment) What is shown in FIG. 1 is the first embodiment of this invention,
The warp threads pulled out from the creel 1 are passed through a sizing machine 2 to form a sizing beam B2. Next, the warp yarns are drawn out from several glued beams 82 prepared in this way and passed through the dryer 3 to form one loom beam B3.

A second embodiment of the invention is shown in FIG.
First, a rough winding beam B1 is formed by the warp drawn out from the creel 1. Next, the warp threads pulled out from this roughly wound beam B1 are passed through a sizing machine 2 to form a sizing beam B2. Finally, the warp yarns are pulled out from several glued beams B2 prepared in this way and passed through a dryer 3 to form a loom beam B3.

When carrying out this invention, it is necessary to use a glue that hardens quickly after gluing, such as a quick-drying glue for roller-type simple partial gluing, or conversely, a glue that hardens slowly or a special glue with low adhesive properties. It is preferable to use

As is clear from the above, according to the present invention, drying is performed in the low-speed beaming process in combination with sizing in the warping process where the warp yarn density is small, so the possibility of warp yarns adhering to each other is reduced. Quality can be improved. Moreover, the capacity of the dryer does not have to be increased and the overall efficiency is not hindered. Further, since a certain amount of water evaporates due to natural drying during the waiting period after forming the glued beam and before proceeding to the next beaming process, the drying capacity in the beaming process can be reduced accordingly. In addition, even if gluing is performed at high speed, the next beaming process cannot be started unless several gluing beams remain, so it is easy to maintain a balance between the two even if drying is performed at low speed.
