What are the advantages of wet-laid composite spunlace nonwoven production technology?
- 2024-11-01
The wet-laid composite spunlace nonwoven production line combines the advantages of dry-laid web forming and wet-laid web forming. It uses viscose and wood pulp fibers as the main raw materials. The products are mainly used for wiping cloth (composite products) and wet toilet paper (flushable products). Its cost is relatively low, and the products can be naturally degraded after use. So, what are the advantages of using wet-laid spunlace technology?
High speed and high yield
Wet-laid composite spunlace nonwoven fabric is a processing method with a relatively high production speed among nonwoven fabrics. Both the speed of the wet-laid production line and the speed of the dry-laid combing production line are relatively high, which is suitable for large-scale production of large-scale products.
Suitable for a variety of fiber raw materials
The raw materials used for wet-laid composite spunlace nonwoven fabrics can not only be wood pulp fibers for papermaking, but also various types and specifications of textile staple fibers, and can also be a mixture of different types of fibers.
Great quality
Because the wet-laid fibers are evenly dispersed, randomly arranged, three-dimensionally distributed, and isotropic in water, the structure of wet-laid nonwoven fabric products is fluffier and softer than traditional paper, and the strength and uniformity of the lower layer of dry-laid nonwoven fabric are high. Using it as the bottom layer can effectively reduce the leakage of wet-laid fibers, and the composite product has a high production rate, good hygroscopicity, high strength, and wide adaptability.
Diversified product types
Due to the wide range of fiber raw materials used, the equipment can adapt to the production of various nonwoven fabrics. In addition, with the application of various finishing equipment, the equipment not only It is suitable for the production of bulk products, and has a wide variety of products and a wide range of applications.
Low raw material cost
The wood pulp fibers used in large quantities as raw materials for wet composite spunlace nonwovens are cheap, the production line speed is high, and the processing cost of the finished fabric is relatively low, so the product is highly competitive in terms of price. Three commonly used fibers The raw materials are softwood pulp, polyester staple fiber and viscose staple fiber.
green production
Wet-laid composite nonwovens entangle fibers through a spunlace process to achieve web reinforcement without the use of chemicals. The fibers used in the wet-laid composite production line are mainly natural fibers and biodegradable. The composite production process has improved The utilization rate of fiber reduces the usage of medium water in the process.
The wetlaid composite spunlace nonwoven production line is an integrated innovation that combines spunlace nonwovens and wet papermaking technology. The end product can have good water absorption and skin-friendliness, and the use of wood pulp fibers can also reduce costs. Biodegradable raw materials such as chopped viscose and wood pulp fibers reduce environmental pollution.
The production process of the Soonercleaning wet-laid composite spunlace equipment set has developed a new type of high-end nonwoven production line with good performance, convenient process adjustment and high cost performance. It is predicted that the promotion of this technology can meet the needs of the high-end nonwoven market in the next ten years, and can provide strong support for the equipment upgrading and technological progress of nonwoven manufacturers at home and abroad.
