JPS5939544B2 - Sizing machine glue penetration promotion and fluffing device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention promotes the penetration of glue into the warp yarns in the sizing section of a sizing machine, suppresses excessive sizing, and improves the fluffiness of the warp yarns, which is required as the speed of looms increases. This invention relates to a sizing machine's glue penetration promotion and fluff-covering device for the purpose of smoothing.

In the sizing section of a conventional general sizing machine, the warp threads enter the sizing liquid in a dry state, pass through a dipping roller and a sizing roller, and then enter the drying process.

If this method alone is used, the fluff of the warp yarns will be in a disordered state, and this fluff condition will not change even after gluing, and the warp yarns will interfere with each other, and in an air jet loom, this will become a serious obstacle, especially blocking the passage of the weft yarns.

Furthermore, since the warp threads remain dry, they are slightly hydrophobic and it is difficult for the size liquid to rapidly penetrate into the core of the warp threads, and it is more hydrophilic when they are slightly moistened than when they are dry. For example, a properly damp towel absorbs water much better than a dry towel.

However, the hydrophilic effect changes depending on the amount of water contained, and excessive water content will conversely impede penetration of the size liquid, resulting in poor sizing and permanent retention, such as moisture entering the size liquid.

The present invention aims to overcome these conventional deficiencies and provide a device capable of achieving the objects stated at the outset.

Next, embodiments of the present invention will be explained with reference to the drawings.

1 is a warp thread, 2 is a glue tank for storing the size liquid 3, 4 is a dipping roller, 5 is a glue roller, and 6 is a glue squeezing roller that is in contact with the upper part of the glue roller 5, and these combine to form the glued part A. Configure.

7 and 8 indicate opposing lower and upper rollers for warp delivery.

The above is already known.

Reference numeral 9 denotes a hot water tank provided on the side of the warp feed roller 7 of the glue tank 3, in which hot water 10 automatically adjusted to an appropriate temperature according to the quality of the warp yarns 1 is stored.

Reference numeral 11 denotes a lower humidifying fluff roller, which is partially exposed above the hot water surface and comes into contact with the humidifying fluff upper roller 12.

This upper roller 12 has a core roller 12a covered with a fiber aggregate 12b.

Reference numeral 13 denotes a transmission for the drive shaft of the humidifying fluffing lower roller 11, which adjusts the rotation of the abutting lower roller 11 to be slightly slower than the warp feeding speed.

In the present invention, in the above structure, the warp yarns 1 were conventionally sent directly to the sizing section A by the lower and upper sending rollers 1 and 8, but a hot water tank 9 is provided in front of the warp yarns 1 to keep the temperature at an appropriate temperature according to the yarn quality of the warp yarns 1. By storing hot water 10 that maintains a constant temperature, the lower humidifying fluff roller 11 that is immersed in this is heated and rotates at an appropriate temperature, so that the hot water adhering to the surface of the roller is transferred to the surface of the opposing humidifying fluff upper roller 12. will be supplied with hot water.

The outer periphery of the core roller 12a of the upper roller 12 is covered with a fiber aggregate 12b, and this outer coating layer does not allow moisture into the outer coating layer even if the water supply due to the rotation of the lower roller 11 is interrupted when the machine is stopped. Since it is desirable that the warp yarns 1 have sufficient water content to retain water and have enough flexibility to allow the warp yarns to sink properly, the constant warp yarns 1 are sent out and form fiber aggregates when passing between the humidifying fluffing rollers 11 and 12. 42b can be absorbed over a wide surface area, and since the rotational speed of the lower roller 11 is slightly slower than the warp speed, the upper roller 12 and the warp 1 rotate in contact with this. The fuzz of the warp threads, which are squeezed and progress in a state where they are sunken into the fiber aggregate 12b (see Fig. 3), changes from the irregular jumbled state shown in Fig. 2 1a to the state shown in Fig. 1b. The warp yarns 1 are fluffed in the yarn direction, treated at an appropriate temperature, and sent in this state to the sizing section A. The warp yarns 1, which are given an appropriate humidity, allow the sizing liquid 3 to penetrate well and make the core sizing effective. can.

In the above, the humidifying fluff roller 12 may be heated with steam, electricity, etc. to maintain an appropriate temperature.

Considering that fiber aggregates originally have heat insulating properties, heat conduction to the roller surface should be hindered, but in the present invention, moisture supplied from the lower roller 11 penetrates into the tissue of the outer covering layer. There is no problem with heat conduction.

Furthermore, when the warp yarns are made of cotton, for example, they contain fat, and raising the temperature can dissolve the fats and oils, and depending on the quality of the yarns, can also serve to dissolve and wash the helium content.

The amount of water given to the roller 12 depends on the surface roughness of the humidifying fluff lower roller 11, the pressing force of the upper roller 12 that rotates against the roller 11 and squeezes back the water, the water level condition of the hot water 10, or It is adjusted by the contact angle between the upper roller 12 and the warp threads 1, and the appropriate temperature and temperature conditions for the warp threads may be set depending on the actual state of processing.

In this embodiment, the outer covering layer of the humidifying fluffing upper roller 12 is the fiber aggregate 12b, but it is not necessarily limited to this, and it is also possible to use a member similar to this. The fiber aggregate showed good results experimentally, and on the other hand, when covering the sponge, good results were initially obtained, but it turned into a linear film in a short period of time and lost surface flexibility, making it unsuitable from a durability point of view. It was recognized that

As described in detail above, the humidified fluffed lower roller, which is partially immersed in a hot water tank in front of the pasting section, is warmed to an appropriate temperature and rotated slightly slower than the warp speed, and the outer periphery of the roller is rotated slightly slower than the warp speed. A humidified fluffed upper roller covered with a material with appropriate moisture content and flexibility is placed in contact with the upper roller, and the warp threads are sent out in contact with this upper roller, so that the warp threads sink into the outer covering layer of the contact roller. Since the appropriate amount of moisture is applied, the penetration of the size liquid into the glued area is good, and at the same time, the glue can be glued while the fabric is fluffed up, achieving good results that cannot be achieved with existing glue processing.
