Process characteristics of imported spunbond dry-laid non-woven fabrics

Imported spunbond dry-laid non-woven fabric is a kind of non-woven fabric.

Non-woven fabrics are also called non-woven fabrics. Non-woven fabrics are composed of directional or random fibers.

It is called cloth because it has the appearance and certain properties of cloth.

To put it simply: it is not intertwined and knitted together by yarns one by one, but the fibers are directly bonded together through physical or chemical methods. Therefore, when you get your clothes When the stick inside is weighed, you will find that you cannot pull out the threads one by one.

According to different production processes, non-woven fabrics can be divided into heat-sealed non-woven fabrics, wet-laid non-woven fabrics, stitch-bonded non-woven fabrics, melt-blown non-woven fabrics, dry-laid non-woven fabrics, needle-punched non-woven fabrics, and water-laid non-woven fabrics. Thorny non-woven fabrics and spunbond non-woven fabrics.

Among the non-woven fabric manufacturing methods, the spunbond method has achieved remarkable rapid development in the past 20 years due to its obvious advantages in manufacturing technology, product performance and production efficiency.

The production process of imported spunbond dry-laid non-woven fabrics is to extrude and stretch the polymer to form continuous filaments. The filaments are laid into a web, and the fiber web is then bonded by itself, thermally bonded, and chemically bonded. Combining or mechanical reinforcement methods can turn the fiber web into a non-woven fabric.

Non-woven fabrics produced using the spunbond process have 4 characteristics: 1. The fiber web is composed of continuous filaments; 2. Excellent tensile strength; 3. There are many process changes, and various methods can be used for reinforcement; 4 .The filament fineness changes in a wide range.
