Description

Technical Field

[0001] The invention relates to the technical field of mesh fabrics, and more specifically to a method for preparing a high-elastic composite mesh fabric. Background Art

[0002] Textile fabrics are related to all aspects of people's lives. With the improvement of living standards, people have higher and higher demands for various functions of fabrics. Traditional fabrics only have a single function. Therefore, with the continuous research and improvement of fabrics, composite fabrics with multiple functions are designed. Such composite fabrics can be used not only for clothing, but also for industry. For example, the prior art publication number is CN210190771U, which is a high-strength wear-resistant composite fabric. The prior art includes a wear-resistant layer, a mesh layer and an adhesive layer. The outer side of the wear-resistant layer is fixedly connected with a protrusion, and the outer surface of the protrusion is fixedly connected with an anti-slip point. The corresponding state of the first through hole on its outer surface and the second through hole on the surface of the connecting mesh layer fully improves the air permeability of the overall fabric, and the elastic fiber cloth material of the connecting mesh layer effectively expands the deformation strength of the composite fabric. At the same time, the setting of the buffer layer that can absorb sweat gives the user a better use experience.

[0003] At present, when composite mesh fabrics are produced, warp knitting machines, composite machines and other equipment are generally used to first make the fabric materials, and then the composite machines are used to composite the multiple layers of fabrics together. For example, a method for preparing a breathable composite fabric is disclosed in the prior art publication number CN118596679A.

[0004] However, the above-mentioned prior art still has the following problems when used: when processing the composite mesh fabric, it is necessary to arrange and place multiple layers of fabric in advance and then composite it. However, since the fabric is soft, it takes a lot of time to arrange it, and the fabric is easy to shift during the composite process, which will cause the stitching of the composite mesh fabric to shift, affecting the firmness and aesthetics of the composite mesh fabric, and traditional composite mesh fabric does not have good antibacterial effect, warmth retention effect and anti-ultraviolet effect, which is easy to cause mold inside the fabric, thereby shortening the service life of the composite mesh fabric. Based on this, the present invention provides a preparation method of a high-elastic composite mesh fabric. Summary of the invention

[0050] The base fabric layer 2, two mesh fabric layers 13, two mesh fabric layers 24 and two wear-resistant layers 5 are sewn together through a reinforcement line 6 to form a fabric body 1, and the mesh fabric layer 13 and the base fabric layer 2 are compounded together through a plurality of protrusions 18 and a plurality of composite grooves 17, the mesh fabric layer 24 and the mesh fabric layer 3, and the wear-resistant layer 5 and the mesh fabric layer 24 are compounded together through a plurality of protrusions 210 and a plurality of composite grooves 29, and hot melt adhesive is filled between the protrusion 18 and the composite groove 17, and between the protrusion 210 and the composite groove 29, so as to improve the composite firmness between the layers of structure, thereby improving the overall strength, elasticity and tensile resistance of the fabric body 1.

[0051] In this embodiment, if Figure 8 As shown, the mesh cloth 21 is made of a plurality of transverse woven wires 211 and a plurality of longitudinal woven wires 212 woven by a warp knitting machine, and a plurality of through holes 213 are formed between the transverse woven wires 211 and the longitudinal woven wires 212, and the transverse woven wires 211 and the longitudinal woven wires 212 are both spandex fibers; the base fabric layer 2 is a mesh cloth 21 formed by weaving a plurality of transverse woven wires 211 and a plurality of longitudinal woven wires 212 by a warp knitting machine, and the transverse woven wires 211 and the longitudinal woven wires 212 are spandex fibers, which have high elasticity, can be quickly deformed when stretched, and quickly return to their original shape, are not easily deformed, and therefore can be reused.

[0055] The preparation method of the above-mentioned high-elastic composite mesh fabric comprises the following specific steps:

[0056] Step 1: first use a two-for-one twisting machine to make a plurality of spandex fibers into a transverse braided yarn 211 and a longitudinal braided yarn 212, use a warp knitting machine to weave the plurality of transverse braided yarns 211 and the plurality of longitudinal braided yarns 212 into a mesh cloth 21, weave a fiber yarn 1 311 and a fiber yarn 2 312 into a hollow mesh cloth 1 31, weave a fiber yarn 3 411 and a fiber yarn 4 412 into a hollow mesh cloth 2 41, weave a braided yarn 1 511 and a braided yarn 2 512 into a wear-resistant mesh cloth 51, and use a two-for-one twisting machine to twist a first winding yarn 61 and a second winding yarn 62 into a reinforcement line 6;

[0057] Step 2: Use a hot press to heat press a composite groove 7 on the surface of the mesh cloth 21, heat press a composite groove 9 on the surface of the hollow mesh cloth 31 and the hollow mesh cloth 41, and use a sewing machine to sew a protrusion 8 on the surface of the hollow mesh cloth 31, and sew a protrusion 10 on the surface of the hollow mesh cloth 41 and the wear-resistant mesh cloth 51;

[0058] Step 3: Use a spray gun to apply some hot melt adhesive in the composite groove 1 7 and the composite groove 2 9, and then composite the base fabric layer 2, the two mesh fabric layers 1 3, the two mesh fabric layers 2 4 and the two wear-resistant layers 5 together;

[0059] Step 4: Use a reinforcing thread 6 to sew the base fabric layer 2, the two mesh fabric layers 1 3, the two mesh fabric layers 2 4 and the two wear-resistant layers 5 together using a sewing machine to obtain a high-elastic composite mesh fabric.

[0060] Among them, Figure 1-4 As shown, the structure of the hot press in the preparation method is as follows: the hot press comprises a processing table 13, a hot pressing assembly 14 is fixedly provided on the top of the processing table 13, the hot pressing assembly 14 comprises two hot pressing rollers 141 distributed up and down, a plurality of hot pressing blocks 142 for hot pressing to form protrusions 1 8 and protrusions 2 10 are fixedly provided on the outer wall surfaces of the two hot pressing rollers 141, one of the hot pressing rollers 141 is movably connected to a mounting plate 1 143 at both ends, and the other hot pressing roller 141 is movably connected to a mounting plate 2 144 at both ends, and the mounting plate 2 144 is fixed to the top of the processing table 13.

After processing the mesh cloth 21, the staff first removes the pad 17, Then, two electric push rods 146 are used to drive the installation plate 143 to separate from the installation plate 2 144, and then the staff installs the pad 17 between the two slide grooves 18, and uses the pad 17 to cover the hot pressing roller 141 between the two installation plates 2 144, and then the hollow mesh cloth 1 31 and the hollow mesh cloth 41 can be transported to process the composite groove 2 9.
