Production process of spunbond nonwoven fabric
The production process of spunbond nonwoven fabric, in short, is to melt the polymer and directly spin it into a web through the melt to manufacture nonwoven fabric. This technique is also affectionately referred to as “S” fabric due to its initial letter “S”. Correspondingly, the production system of spunbond nonwoven fabric is referred to as the “S” system or “SB” system. The production line using the spunbond process is called the spunbond nonwoven fabric production line. In order to further improve the efficiency and product quality of the production line, multiple spunbond spinning systems may be configured on one production line, thereby forming different types of spunbond nonwoven fabric production lines such as SS or SSS.
Definition and terminology of spunbond method
The spunbond method produces non-woven fabrics by melt spinning into a web, which is called “S” fabric. The production line can be equipped with multiple spinning systems.
Overview of Production Process
Next, let’s take a detailed look at the basic production process of spunbonded nonwoven fabrics: first, the raw materials and accessories need to be prepared, and after the steps of conveying, measuring and mixing, extrusion and melting, they are then filtered and measured by the melt before entering the spinning stage. After spinning is completed, cooling, stretching, mesh laying and other operations are required to finally form the fabric. Subsequently, after post-processing, online monitoring, slitting, winding and other processes, the final product is obtained. The production of non-woven fabrics requires processes such as preparing raw materials, melting, filtering, spinning, cooling, and finally finishing to obtain finished products.
The diversity and application of non-woven fabrics
Non woven fabrics have broken the shackles of traditional textiles, becoming a clear stream in the textile industry with their simple process flow, efficient production speed, huge output, low cost, wide range of uses, and diverse raw material sources. Its application fields are extensive, covering multiple aspects such as medical and health care, home decoration, clothing lining, industrial filtration, agricultural protection, etc.
Medical and Home Applications
Specifically, non-woven fabrics play an important role in the field of healthcare, such as the manufacturing of surgical gowns, protective clothing, masks, and other medical supplies; Meanwhile, it is also widely used in home decoration, such as wall coverings, tablecloths, etc.
Industrial and agricultural applications
In the industrial field, non-woven fabrics are used as filter materials, insulation materials, etc; In addition, agricultural fabrics such as crop protection fabrics and irrigation fabrics are also important application directions for non-woven fabrics.
Applications in other fields
Not only that, non-woven fabrics have also demonstrated their unique application value in other fields such as space cotton and insulation materials.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
