Wet-laid non-woven fabric technology is a new technology that utilizes papermaking equipment and processes to produce non-woven fabric products or paper fabric composite materials. Widely used in developed countries such as Japan and the United States, it has formed the advantage of large-scale industrialization. This technology breaks through traditional textile principles and avoids complex processes such as carding, spinning, and weaving that require high labor intensity and low production efficiency. By utilizing wet forming technology in papermaking, fibers can form a network on the papermaking machine in one go, forming a product. Greatly reduces labor intensity and improves labor productivity. This process does not repeat the processing of fiber raw materials. Directly producing fiber products with short fibers can reduce energy consumption, manpower, material resources, and manufacturing costs.
Compared with other fiber product manufacturing methods, it has the following characteristics:
Beneficial for the transformation of small-scale papermaking production and the control of environmental pollution
The wet PLA corn fiber non-woven fabric technology can fully utilize existing papermaking equipment and can be converted into non-woven fabric products without significant technological transformation. This process does not produce dust and harmful gases, and the entire production process from feeding to product storage does not discharge waste liquid. Controlling environmental pollution and developing new products are practical technologies for small-scale papermaking.
Beneficial for protecting water resources
Wet-laid non-woven fabric production requires less water. Water is only used as a fiber transport medium in the system and will not be discharged, causing damage and waste to water resources. The small-scale papermaking production process is simple, with no water recovery facilities and direct discharge of production water. The application of this technology can alleviate the excessive development of water resources in small paper enterprises, which is beneficial for protecting water resources.
The source of raw materials is extensive
Wet non-woven fabric has strong adaptability to raw materials and can be designed reasonably according to product usage requirements. Fiber raw materials can be widely used. In addition to plant fibers, polyester, polypropylene, vinylon, adhesive fibers, and glass fibers can also be selected. These raw materials can be used alone or mixed in proportion to give the product special functions. There are many raw material manufacturers and a wide variety of raw materials in our country.
There are a wide variety of products and a wide range of application fields
PLA non-woven fabric is a brand new fiber product, basically composed of a fiber mesh (non woven mesh) structure. Due to its structural characteristics, it is significantly different from woven and knitted fabrics. As long as different fiber materials, processing methods, and post-treatment processes are selected, non-woven fabric products with different properties and wide applications can be produced. It is widely used in many fields.
1. Medical and health care: surgical gowns, hats, masks; Bed sheets and pillowcases; Bandages, ointments, etc.
2. Home decoration and clothing: clothing lining, dust-proof clothing, labor protection clothing, dust-proof masks, synthetic leather, shoe sole leather, vacuum cleaner filter bags, shopping bags, sofa bags, etc.
3. Industrial fabrics: speaker soundproofing felt, battery separator paper, glass fiber reinforced base cloth, filter material, electrical insulation cloth, cable cloth, tape cloth, etc.
4. Civil construction: geotextile, sound insulation material, thermal insulation material, waterproof material base cloth, oil felt base cloth.
5. Automotive industry: carburetor filters, air filters, insulation felt, shock-absorbing felt, molding materials, indoor decoration composite materials.
6. Agricultural horticulture: root protection cloth, seedling cultivation cloth, insect resistant cloth, frost resistant cloth, soil protection cloth.
7. Packaging materials: Composite cement bags, grain packaging bags, bagging materials, and other packaging substrates.
8. Other: map cloth, calendar cloth, oil painting cloth, cash binding tape, etc.
Has enormous market potential and significant economic benefits
Wet non-woven fabric has advantages such as fast network speed, short process flow, high labor productivity, and low cost. Its labor productivity is 10-20 times that of dry method, and the production cost is only 60-70% of dry method. Has strong market competitiveness and good economic benefits. At present, the production of wet nonwoven fabrics accounts for more than 30% of the total production of nonwoven fabrics and is still growing. Compared with developed countries, China has enormous market potential.
Beneficial for resource regeneration and white pollution control
For disposable products and packaging materials that are prone to white pollution, their biodegradability can be improved by adding additives, or their recycling performance can be improved by using functional materials, thereby reducing recycling costs. Beneficial for resource recycling and suppressing white pollution.
In short, the technology of wet-laid non-woven fabric is in the ascendant and has good development prospects. The development and production of wet non-woven fabrics comply with national industrial policies and sustainable development plans. It is beneficial for improving overall labor productivity, reducing production costs, and has important economic and social benefits in controlling environmental pollution and rational utilization of resources.
