Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a gluing method, and more particularly to a gluing method using a simultaneous sizing method.

(Prior Art and its Problems) Generally, when sizing is performed, the warp sheet is passed through a sizing liquid tank.

By the way, there are two types of sizing machines: a single-size box type with one PII liquid 412 and a multi-size box type with a plurality of sizing liquid tanks. In the case of the single size box type, the yarn sheet is passed through the size liquid in the size liquid tank as it is, so the yarn density is high, and the yarn pitch is small so that the size liquid does not come into contact with the entire surface of the yarn. adhesion and penetration may be insufficient.

On the other hand, the multi-size box type has a larger thread pitch and does not have the problems of the single-size box type described above, but the number of size boxes increases and the overall structure of the sizing machine inevitably becomes larger.

In addition, since the distance from each size tank to the drying chamber is different, the degree of dryness of the yarn is different, resulting in a decrease in yarn quality. Since there are subtle differences in load, etc., unevenness in the amount of R and tension occurs, which has the disadvantage of deteriorating the quality of the fabric.

(Means for Solving the Problems) The present invention provides a sizing method that allows a sizing liquid to adhere to and permeate the entire surface of the yarn even in a single-size box type that is structurally smaller. The purpose is to

In order to achieve this object, the present invention attempts to pass a warp sheet through a size liquid tank in a state where the warp sheet is divided into a plurality of layers.

That is, the basic structure of the present invention is, for example, as shown in FIG. 1, the warp sheet is divided into two upper and lower layers on the upstream side of the size liquid 4!11 in the direction of travel of the warp sheet,
The divided warp sheets S1 and S2 are guided to immersion rolls 31 and 33 in the size tank 1 by guide rolls GR1 and Ga4, respectively.

(Function) According to what is shown in FIG. 1, the vertically divided warp sheets S1 and S2 are separated from each other, and the immersion roll 3 is gradually reduced in relative distance therebetween.
I am guided by 1. That is, both sheets S1 and S2 are immersed in size liquid while being separated from each other.
1. S2 is sent between the sizing rolls 51, 53 and squeezing rolls 71, 73 via a common immersion roll 31, 32, so two warp sheets 31
, S2 becomes one warp sheet after passing through the first immersion roll 31. That is, the first immersion roll 3
On the supernatant side of No. 1, each warp forming the warp sheet is uniformly exposed to the size liquid over the entire surface. In addition, when dividing the warp sheet into two upper and lower layers, it is preferable to divide the warp yarns alternately in the width direction of the warp sheet, so that there are no adjacent yarns in the sheet width direction, This ensures that the entire surface of the warp threads is immersed in the size solution.

(Example) In the above explanation, each of the warp sheets S1 and S2 divided into two layers passes through the common immersion rolls 31 and 33 from the guide rolls GRI and Ga4. The state in which both warp sheets are separated is up to the first immersion roll 31, and depending on the yarn type, this may be too short for the size liquid to adhere to the entire surface of the yarn.

Therefore, as shown in FIG. The sheets are separated, and the entire yarn is directly immersed in the size solution for a long period of time.

Further, as shown in FIG. 3, two immersion rolls 311 and 331 are arranged vertically apart, and the upper warp sheet S1 is passed through the upper immersion roll 311, and the lower warp sheet S2 is passed through the upper warp sheet S1. are passed through the lower immersion roll 331 to the common sizing roll 51.
．． 53 and squeezing rolls 71 and 73.

Furthermore, if the immersion distance of each warp sheet S1, S2 into the size liquid is still short, as shown in FIG. Immersion 3 roll corresponding to S2 is 2
The upper warp sheets si are separated from each other by the upper immersion rolls 312 and 333, which are spaced apart from each other.
If the lower warp sheet S2 is sent between the common sizing rolls 51.53 and squeezing rolls 71.73 via the lower immersion rolls 313 and 334, the immersion sheet S2 passing through first sion roll 312, 313 and the next passing immersion roll 3
33 and 334 can be passed through the paste solution for a longer time by the distance between the rows.

In the above description, the warp sheet is separated into two layers, but the present invention is not limited to this. It goes without saying that it may be better to separate them more than J.

(Effects of the Invention) According to the present invention, the warp sheet sent into the size liquid tank is fed into the size liquid in multiple layers by, for example, alternately distributing each warp in the sheet width direction up and down. , the entire surface of the threads constituting each warp sheet can be exposed to the size liquid,
The paste can be applied uniformly over the entire area to each prefecture,
High quality sizing yarn can be obtained.
