Problems solved by technology

[0002] In the current production of non-woven grid composite non-woven fabrics, the weft laying device lays all the weft yarns evenly on the chain hooks. Since the weft laying device of this structure operates back and forth, its running speed has a certain limit. When the speed When it is too fast, the inertia of returning to stop is particularly large during reciprocating operation, which will easily cause equipment vibration, friction, rapid damage, and production accidents, so the improvement of its production efficiency is limited.
In addition, the existing non-woven mesh cloth (including the rotary weft laying method) is sizing at the same time after the warp and weft yarns are formed into a net, so it is easy to appear that the warp and weft yarns are glued due to the surface of the glue-like adhesive. The effect of tension makes the warp and weft yarns arranged unevenly, which affects the appearance of the final product and reduces the physical properties of the product

Embodiment 1

[0097] Example 1 produces a square nonwoven mesh composite nonwoven fabric.

[0098] ① Use glass fiber as warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 136Tex). The continuous fiber weft yarn 30 is continuously drawn out from the weft yarn head 22 by the rotation of the large rotating disk 23 of the rotary weft laying machine, and the weft yarn 30 is inserted into the rotating rotating screw by the yarn guide eye 24 and the yarn guide rod 25 In the spiral groove of 1, the weft yarn is evenly wound on the two rotating screws 1; the rotating screw 1 rotates evenly, and the arranged weft yarns move forward at a uniform speed.

[0099] The structure of the rotary weft laying machine includes a central shaft 21, a large rotating disk 23, a screw rotating head 36, a rotating screw 1, a yarn guide rod 25, a yarn guide eye 24, etc. The central shaft 21 is equipped with a large rotating disk 23, which rotates The turntable 23 rotates around the central axis 21, a plurality of we...

Embodiment 2

[0108] Example 2 produces a diamond-shaped nonwoven mesh composite nonwoven fabric.

[0109] ① Use glass fiber as warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 68Tex). Continuous fiber weft yarns (also called diagonal ribs, because they do not form a 90° angle with the warp yarns) 30, through the rotation of the large rotating disk 23, the weft yarns are drawn out from the weft yarn head 22 without interruption, and the warp guide eyes 24, The guide rod 25 allows the weft yarn 30 to be inserted into the spiral groove of the rotating rotating screw 1 so that the weft yarn is wound on the left and right rotating screws 1 in a uniform diamond shape; the rotating screw 1 rotates evenly, and the arranged weft yarns move forward at a uniform speed.

[0110] The structure of the rotary weft laying machine includes a central shaft 21, a large rotating disk 23, a screw rotating head 36, a rotating screw 1, a yarn guide rod 25, a yarn guide eye 24, etc. The central shaft 21 is equ...

Embodiment 3

[0119] Example 3 Production of square nonwoven mesh composite nonwoven fabric

[0120] ① Use glass fiber as warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 68Tex). Continuous fiber weft yarn 30, through the rotation of the large rotating disk 23 of the rotary weft laying machine, the weft yarn 30 is drawn out from the weft yarn head 22 without interruption, and the weft yarn is inserted into the rotating rotating screw by the yarn guide eye 24 and the yarn guide rod 25 In the screw groove of 1, the weft yarn is evenly wound on the left and right rotating screws 1; the rotating screw 1 rotates evenly, and the arranged weft yarns move forward at a uniform speed.

[0121] The structure of the rotary weft laying machine includes a central shaft 21, a large rotating disk 23, a screw rotating head 36, a rotating screw 1, a yarn guide rod 25, a yarn guide eye 24, etc. The central shaft 21 is equipped with a large rotating disk 23, which rotates The turntable 23 rotates around th...

Abstract

The invention discloses a method for making a non-woven mesh composite non-woven fabric with a rotary weft laying method. In the method, continuous fibers, a non-woven fabric material and a colloidal bonding agent are taken as original auxiliary materials, and a brand-new rotary weft laying-sizing way is adopted, so that weaving of square and rhombus non-woven mesh composite non-woven fabric is realized. By adopting the method, the conventional weaving concept and compounding process are changed in a disruptive way, and the mechanical structural characteristics of a material are changed, so that the comprehensive performance and production efficiency of a product are greatly increased, and the material cost of a relevant strong fabric is greatly lowered.

Description

Technical field [0001] The invention belongs to the fields of textiles, non-woven materials and composite materials. Background technique [0002] In the current production of non-woven mesh composite non-woven fabrics, the weft spreader lays all the weft yarns evenly on the chain hooks. Since the weft spreader of this structure is a back and forth operation mode, its back and forth running speed is limited. When it is too fast, the stopping inertia during reciprocating operation is particularly large, which is likely to cause equipment jitter, rubbing, rapid damage, and production accidents. Therefore, improving its production efficiency is limited. In addition, the existing non-woven mesh fabrics (including the rotary weft laying method) are sizing at the same time after the warp and weft yarns are formed into a net. Therefore, the warp and weft yarns are prone to be glued, due to the surface of the gluey adhesive. The effect of tension causes uneven arrangement of warp and we...
