Why are nonwoven materials diverse?
The bag made of non-woven material is a typical non-woven environmental protection bag, which is widely used in the market. Some people say that non-woven fabric is a kind of magic material. Why do they say so? What is the basis for that? The reason why it is praised by people is that it is closely related to the diversity of non-woven materials.
There are many kinds of non-woven fabrics, mainly Spunlaced non-woven fabrics, wet non-woven fabrics, sewing non-woven fabrics and so on. Let's have a specific understanding.
Spunlaced non-woven fabric, spunlaced process is to spray high-pressure micro water into one or more layers of fiber network, so that the fibers are entangled with each other, so that the fiber mesh can be reinforced and has certain strength.
Thermal bonded non-woven fabric refers to adding fibrous or powdery hot-melt bonding reinforcement materials into the fiber mesh, and then heating, melting and cooling to form a cloth.
Wet process non-woven fabric, this kind of non-woven fabric is to open the fiber raw materials in the water medium into single fiber, and mix different fiber raw materials to make fiber suspension slurry. The suspension slurry is transported to the meshing mechanism, and the fiber is netted in the wet state and then reinforced into cloth.
Spunbonded non-woven fabric, spunbonded non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filament. The filament is laid into a net, and the fiber mesh is then self bonded, thermally bonded, chemically bonded or mechanically reinforced to make the web into a non-woven fabric.
Needle punched non-woven fabric, needle punched non-woven fabric is a kind of dry non-woven fabric. Needle punched non-woven fabric uses the puncture effect of needle to reinforce the fluffy fiber mesh into cloth.
Sewing non-woven fabric, sewing method is to use the warp knitting coil structure to strengthen the fiber mesh, yarn layer, non-woven materials or their combination to make non-woven fabric.
Different environmental protection bag products are basically made of these different non-woven materials. Through different colors, styles and material configuration, the shapes of environmental protection bag products are tens of thousands, which are deeply loved by consumers.
