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 A square nonwoven grid composite nonwoven was produced.

[0098] ① Glass fiber is used as the upper warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 136Tex). The weft yarn 30 of continuous fiber, through the rotation of the large rotary disc 23 of the rotary weft laying machine, the weft yarn is drawn out from the weft yarn head 22 without interruption, and the weft yarn 30 is inserted into the rotating rotary screw through the yarn guide eye 24 and the yarn guide rod 25 1, the weft yarn is evenly wound on the two rotating screws 1; the rotating screw 1 rotates evenly, and the arranged weft yarn moves 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., a large rotating disk 23 is installed on the central shaft 21, and the rotating large Turning disk 23 rotates around centr...

Embodiment 2

[0108] Example 2 A diamond-shaped nonwoven mesh composite nonwoven fabric was produced.

[0109] ① Glass fiber is used as the upper warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 68Tex). The weft yarn of continuous fiber (also can be referred to as oblique rib, because it is not 90 ° angle with warp yarn) 30, by the rotation of large rotating disk 23, weft yarn is drawn out continuously from weft yarn end 22, through guide eyelet 24, The yarn guide rod 25 allows the weft yarn 30 to be embedded in the screw groove of the rotating rotary screw 1, so that the weft yarn is evenly diamond-shaped and wound on the left and right rotary screw 1; the rotary screw 1 rotates evenly, and the arranged weft yarns move forward in translation 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., a large rotating d...

Embodiment 3

[0119] Example 3 Production of Square Nonwoven Mesh Composite Nonwoven Fabric

[0120] ① Glass fiber is used as the upper warp yarn (alkali-free 68Tex) and weft yarn (alkali-free 68Tex). The weft yarn 30 of continuous fiber, through the rotation of the large rotary disc 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 rotary screw through 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 two rotating screws 1; the rotating screw 1 rotates evenly, and the arranged weft yarn moves 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., a large rotating disk 23 is installed on the central shaft 21, and the rotating l...

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.
