Description

Mesh preparation system

Technical Field

The utility model relates to a mesh preparation technical field especially relates to a mesh preparation system.

Background

The mesh product is widely applied in production and life, but the traditional manufacturing method generally has the advantages of low production speed and low efficiency due to the fact that the mesh product is divided into warps and wefts during manufacturing, is of a single-layer structure, is small in engaging force between the warps and the wefts, is easy to loose and is wasted in materials. For example, a mesh fabric is used as a fabric with mesh holes, and is widely used for summer clothing and also for articles such as curtains and mosquito nets, but the production speed is slow and the efficiency is low regardless of woven mesh fabrics or knitted mesh fabrics.

Secondly, taking the grid cloth in the construction industry as an example, the products are as follows: the product can be widely applied to wall reinforcing materials, cement product reinforcing materials, stone back-pasting nets, reinforced plastic framework materials, grinding wheel base cloth, building seam-embedding belts, pavement geogrids and the like. The traditional manufacturing method has the defects of low production speed and efficiency, small engaging force between warp and weft threads, easy slippage and the like.

Secondly, taking 3D spacer fabric as an example, commonly known as extra-thick sandwich mesh cloth, the three-dimensional space-saving fabric is very suitable for mattresses, cushions and the like, has a double-layer mesh design, and intermediate monofilaments are vertically arranged at an angle of X-90 degrees, breaks through the traditional loose fiber 0-degree support, has air permeability, moisture permeability and elasticity, is in a multilayer structure, is thick, but has complex production process, limited bearing capacity and high cost and efficiency.

Finally, taking the waterproof and breathable film as an example, the waterproof and breathable material is widely used in the fields of industry and life, the technology is introduced from Europe and America, and although the technology is developed for many years, the manufacturing technology of domestic products is still quite laggard and the air permeability is low. The traditional waterproof breathable material mainly comprises three layers: the upper layer and the lower layer are PP spun-bonded non-woven fabrics, and the middle layer is a PE high-molecular breathable film. The upper and lower layers of spun-bonded non-woven fabrics mainly have the functions of enhancing tensile force and resisting hydrostatic pressure, and protect the middle layer (PE high molecular breathable film), and the middle layer PE high molecular breathable film is mainly used for true ventilation. The production process mainly comprises three types: 1. and (4) casting and compounding. The process is that plastic particles are hot-melted and then compounded by depending on the viscosity of the plastic. The process is simple but hardly breathable. 2. Spraying glue or scraping glue for compounding (hot melt glue compounding). The process is firstly applied to sanitary towels, diapers and protective clothing, and at present, domestic manufacturers almost use the process for production. But the air permeability is lower, because the micropore of middle PE polymer ventilated membrane is blocked up by a large amount of hot melt adhesive, in addition, the fatal shortcoming is exactly that the temperature resistance is very low, because this glue is a pressure sensitive adhesive (non-setting adhesive) in fact, as long as there is certain temperature, the non-woven fabrics will come unstuck the layering. 3. And (6) hot-pressing and compounding. The product is a product which can really reach the European Union standard in China at present and is the latest technology in China. But the disordered hot pressing of the compound on the front surface and the back surface can also seriously block the micropores of the middle breathable film, thereby greatly influencing the breathable performance and having higher manufacturing cost.

In terms of manufacturing process, the technical requirements of the waterproof breathable material are much higher than that of a common waterproof material; the production process of the waterproof breathable film mainly comprises three steps: 1. and (4) casting and compounding. The process is that plastic particles are hot-melted and then compounded by depending on the viscosity of the plastic. The disadvantage is that it is hardly permeable to air. 2. Spraying glue or scraping glue for compounding (hot melt glue compounding). The process is firstly applied to sanitary towels, diapers and protective clothing, and at present, domestic manufacturers almost use the process for production.

The speed of the PE high-molecular breathable film falling on the upper part of the net formed by the first blanking assembly on the crawler is the same as the running speed of the crawler. In order to ensure that the silk threads contained in the upper and lower nets of the PE high-molecular breathable film can be aligned, the distance between the central axis of the first discharging pipe at the leftmost end contained in the second discharging assembly and the central axis of the first discharging pipe at the rightmost end contained in the first discharging assembly is integral multiple of the distance between the central axes of two adjacent first discharging pipes.
