Problems solved by technology

[0003] ①Traditional woven fabrics adopt single-weft weaving, and only one weft yarn can be introduced in each weaving cycle, so the weaving production efficiency is very low
In each weaving cycle, the binding thread can only be looped once, so the weaving efficiency of the binding thread is relatively low, and the material cost is high
[0006] ④ Traditional nonwovens (non-woven fabrics) have no straight continuous fibers in the material, and the strength of the fabric depends on the entanglement between fibers (such as needle-punched non-woven fabrics and spunlace non-woven fabrics, etc.) and between short fibers. The strength of the fabric produced by the bonding force of the adhesive is relatively low
In the case of low total grammage, the strength is very low and cannot be applied in large quantities
Increasing the strength by increasing the thickness and total weight will greatly increase the manufacturing cost and raw material cost of the product

Embodiment 1

[0027] ①Using glass fiber as warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 136Tex), use a weft laying device to draw the weft yarn from the weft yarn creel, and hang it in parallel on the chain hook of the weft laying device without interruption. The weft yarns of the non-woven mesh are arranged in parallel, and the forward speed of the chain hook and the composite drum are carried out at a relative speed difference, and the speed difference ratio is 3 times.

[0028] ② At the same time, the warp yarns are drawn out from the warp yarn creel, perpendicular to the weft yarns, and arranged neatly; the arrangement density of the warp yarns is 4 yarns / cm, and the warp yarns are introduced into the composite point of the composite drum in one layer, and the speed of its extraction is basically synchronized with the composite drum , the line speed is 8M / min.

[0029] ③The method of spraying glue is used for sizing, so that the acrylic hydrosol is evenly distributed on the ...

[0035] ①Using carbon fiber as the warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 136Tex), the weft yarn is drawn out from the weft yarn creel by using a weft laying device, and is hung in a parallel arrangement on the chain hook of the weft laying device without interruption to realize non-toxic The weft yarns of the weaving grid are arranged in parallel, and the forward speed of the chain hook and the compound drum are carried out with a relative proportional speed difference, and the speed difference ratio is 2 times.

[0036] ② At the same time, the warp yarns are drawn out from the warp yarn creel, perpendicular to the weft yarns, and arranged neatly; the arrangement density of the warp yarns is 3 yarns / cm; the warp yarns are introduced into the composite point of the composite drum in two layers, and the speed of its introduction is basically synchronized with the composite drum , the line speed is 18M / min.

[0037] ③ Sizing is carried out by dipping, so that th...

Embodiment 3

[0043] ① Use polyester fiber as warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 136Tex), use a weft laying device to draw the weft yarn from the weft yarn creel, and hang it in parallel on the chain hook of the weft laying device without interruption. To realize the parallel arrangement of the weft yarns of the non-woven mesh, the forward speed of the chain hook and the composite drum are carried out at a relative speed difference, and the speed difference ratio is 2 times.

[0044] ② At the same time, the warp yarns are drawn out from the warp yarn creel, and arranged vertically to the weft yarns; Synchronously, its line speed is 10M / min.

[0045] ③The method of spraying glue is used for sizing, so that the wood glue is evenly distributed on the warp and weft yarns.

[0046]④The gel-like adhesive on the warp and weft yarns is still in a wet state, and is composited with the non-woven material on the composite drum, and the non-woven material is composited in two lay...

Abstract

The invention discloses a method for producing nonwoven griddling reinforced compound non-woven fabrics. The method is characterized in that the invention adopts a new technical proposal that a continuous fiber, a non-woven fabric material and gelatineous adhesive agent are taken as raw materials, by adopting a mode of continuous filament multi-head weft-covering, the grid is formed and the glue is applied on the production line, then the grid is compounded with the nonwoven fabrics and the obtained product is then dried and finalized, thus producing a new strengthening nonwoven grid reinforced compound nonwoven fabrics. The technology provided by the invention totally changes the traditional weaving concept and compounding technology, changes the structural characteristics of mechanics of the materials, thus drastically improves the overall property and the production efficiency of the product and greatly reduces the material cost of the relevant strengthening fabrics.

Description

technical field [0001] The invention belongs to the fields of textile, nonwoven materials and composite materials. Background technique [0002] The following problems and shortcomings exist in traditional fabrics: [0003] ①Traditional woven fabrics adopt single-weft weaving, and only one weft yarn can be introduced in each weaving cycle, so the weaving production efficiency is very low. Increasing the output and efficiency by increasing the speed of the loom will encounter problems such as high noise, high production costs, and high technical requirements for operators. [0004] ②The warp and weft yarns of traditional woven fabrics are interwoven or twisted, and each yarn is wavy and bent and staggered. When the fabric material is stressed, its strength cannot be fully exerted. The strong utilization rate of its material is low. [0005] ③The warp and weft yarns in traditional warp knitted fabrics are fixed by binding threads. Each weaving cycle can only realize one-t...
