Problems solved by technology

[0006]However, the above process also has defects. First, it does not use any means to control the amount of glue (binder) applied, which may lead to excessive glue application The situation that affects the performance of non-woven fabric products; secondly, in the production process of double-layer non-woven fabrics, the side of the single-layer non-woven fabric with the PE film must face a layer of new flat and wrinkle-free film ( PE film) or the conduction belt, after the double-layer latitude-free cloth is dried and shaped, the double-layer latitude-free cloth must be peeled off from the new flat and wrinkle-free film (PE film) or the conduction tape, such a process The process limits the composite direction of single-layer non-weft fabric and fiber, and can only produce double-layer non-weft fabric products with the composite form of fiber-fiber-PE film, which cannot meet the requirements of double-layer non-weft fabric products with the composite form of fiber-PE film-fiber.

Embodiment 1

[0059] Embodiment 1: Production line of double-layer non-weft fabric

[0060] A production line for double-layer non-woven fabrics, such as figure 1 As shown, it includes creel 1, transitional creel 2, splitting creel 3, warping system 4, front tractor 5, tension roller 6, spreading system 7, gluing system 9, unwinding film system 8, drying Sizing system, rear tractor 14, trimming device 15, cloth storage frame 16 and winder 17.

[0061] In this production line, the tow 001 is released through the creel 1, the transition creel 2 and the split creel 3, and then enters the gluing system after passing through the warping system 4, the front tractor 5, the tension roller 6 and the spreading system 7 in sequence. 9. In the gluing system 9, the tow 001 is immersed in the glue solution to form a dipping sheet 004 (that is, the tow after gluing). The unwinding film system 8 releases the transverse sheet coil 007 (in the production of single-layer non-weft fabric, the unwinding film...

Embodiment 2

[0072] Embodiment 2: the production technology of ultra-high molecular weight polyethylene fiber double-layer non-weft cloth

[0073] Present embodiment adopts the production line in embodiment 1, comprises the steps:

[0074] 1. Production of single-layer non-weft fabric:

[0075] (1a) Warp the ultra-high molecular weight polyethylene fiber tow in an ultrasonic water tank, and send it to the gluing system after spreading;

[0076] (1b) In the gluing system, two spreader rollers are used to flatten the tow on a horizontal plane and immerse in the glue solution; the solid content of the glue solution is 15%.

[0077] (1c) The dipped thin sheet formed after the tow is glued is compounded with the PE film on the composite roll. In the compounding process, pressure is applied to the PE film by the pressure roller, so that the PE film squeezes the tow on the compound roll, extruding (1d) After compounding, the composite sheet is formed and enters the drying and shaping roller that ...

Embodiment 3

[0091] Embodiment 3: the production technology of aramid fiber double-layer non-weft cloth

[0092] In this embodiment, the tow is aramid fiber, and when the transverse sheet coil is combined with the tow, one side of the fiber layer in the transverse sheet coil faces the tow. The pressure of the pressure roller in step 1c is adjusted to 0.05-0.1MPa, and the pressure of the pressure roller in step 3c is adjusted to 0.1-0.2MPa.

[0093] The rest of the steps and conditions in the process are the same as those in Example 2, and the aramid fiber double-layer non-weft fabric is obtained.

[0094] The yarn content of the aramid fiber double-layer non-weft fabric prepared in this embodiment is more than 90%, and the glue content is 4%-6%.

Abstract

The invention belongs to the technical field of non-woven cloth production, and particularly relates to a production process and a production line of double-layer non-woven cloth. Aiming at the defects in the prior art, the production process of the double-layer non-woven cloth provided by the invention comprises the following steps: (1) producing single-layer non-woven cloth; (2) making single-layer non-woven cloth into a transverse sheet coiled material; (3) enabling the tows to be subjected to beaming, filament spreading and gluing and then compounded with the transverse sheet coiled material on a compounding roller, and in the compounding process, applying pressure to the transverse sheet coiled material through a pressing roller, so that the transverse sheet coiled material extrudes the tows on the compounding roller; and (4) after the tows and the transverse sheet coiled material are compounded, performing drying shaping, edge cutting and rolling to obtain the double-layer non-woven cloth. The invention also provides a production line for the process. According to the technical scheme, the double-layer non-woven cloth with low glue content and high yarn content can be prepared, and the performance of downstream products of the non-woven cloth can be improved.

Description

technical field [0001] The invention belongs to the technical field of weft-free fabric production, and in particular relates to the production of weft-free fabric with high-performance fibers such as ultra-high molecular weight polyethylene fibers and aramid fibers as base materials. It specifically relates to a production process and production line of a double-layer non-weft cloth. Background technique [0002] High-performance fiber "UD" non-weft fabric is based on high-performance fiber, such as ultra-high molecular weight polyethylene fiber and aramid fiber. combined, and then formed by orthogonal composite lamination. It has excellent properties such as soft hand feeling, low density, abrasion resistance, impact resistance, and strong cutting toughness. It is the bulletproof material with the highest strength and the lightest specific gravity in the world today. [0003] In the prior art, the production process of the weft-free fabric is to spread the tow evenly in...
