Wet-laid non-woven fabric technology is a new technology that uses paper-making equipment and processes to produce non-woven fabric products or paper composite materials. This technology breaks through the traditional textile principles, avoids the complicated processes of carding, spinning, knitting and other high labor intensity and low production efficiency. It makes reasonable use of the papermaking wet web technology, so that the fiber has a good application prospect in the production process. It is formed once on the paper machine to form the product. Greatly reduce labor intensity and increase labor productivity. There is no repeated processing of fiber raw materials in this technology. Fiber products are directly made of short fibers, which can reduce energy consumption, save manpower and material resources, and reduce manufacturing costs.
Compared with other manufacturing methods of fiber products, it has the following characteristics:
1. It is conducive to the conversion of small-scale papermaking and the control of environmental pollution.
Wet-laid non-woven fabric technology can make full use of existing papermaking equipment and can be transformed into non-woven products without major technical transformation. The process does not produce dust and harmful gases, and does not discharge waste liquid from the feeding to the storage. Controlling environmental pollution and developing new products is a practical technology for small papermaking.
2. Conducive to the protection of water resources.
Wet non-woven fabrics use less water. Water can only be recycled in the system as a transport medium for fibers. No discharge to the outside, no damage and waste of water resources. The small-scale papermaking production process is simple, and there is no water recycling facility. The production water is directly discharged. The popularization and application of this technology can alleviate the over-exploitation of small papermaking water resources and help protect water resources.
3. Extensive sources of raw materials.
Wet-laid non-woven fabrics have strong adaptability to raw materials due to the technical characteristics of weaving nets. Reasonable design can be made according to the final use requirements of the product, and fiber raw materials can be widely selected. In addition to plant fibers, polyester, polypropylene, vinylon, viscose and glass fibers can also be used as raw materials. These raw materials can be used alone or mixed in proportions, which have a special effect on the product. There are many raw material manufacturers in China, and their sources are extensive.
4. There are many types of products and a wide range of applications.
Wet-laid non-woven fabric is a new type of fiber product, which is different from woven fabrics and knitted fabrics due to its structural characteristics. They basically consist of fiber networks (not yarn networks). As long as you choose different fiber raw materials, different processing methods and different finishing techniques, you can produce non-woven products with a wide range of properties and uses. It has been widely used in many fields.
Medical and health care: surgical gowns, caps, masks; bed sheets and pillowcases for patients; bandages, plasters, etc.
Home decoration and clothing: clothing lining, dust-proof clothing, labor protective clothing, dust-proof mask, artificial leather, shoe insole leather, vacuum cleaner filter bag, shopping bag, sofa bag, etc.
Industrial cloth: sound insulation felt for loudspeaker, battery diaphragm paper, fiberglass reinforced bottom cloth, filter material, electrical insulation cloth, cable cloth, tape cloth, etc.
