Disposable masks are not new to us, but many non-woven fabrics may not be understood; in fact, many disposable masks are made of non-woven fabrics, but this does not mean that all non-woven fabrics Can be used as raw materials for processing masks. Let’s follow the disposable mask manufacturers to understand the simple classification of non-woven fabrics.
- Spunlace non-woven fabric. Spray high-pressure fine water on one or more layers of fiber mesh to make the fibers entangle with each other, so that the fiber mesh is strengthened and has a certain strength.
- Thermally bonded non-woven fabric. Refers to the fiber or powdered hot melt adhesive reinforcement material added to the fiber web, and then heated, melted, cooled and strengthened into a cloth.
- Pulp air-laid non-woven fabric. It can also be called clean paper and dry paper non-woven fabric. It uses the air-laid technology to open the wood pulp fiber board into a single fiber state, and then uses the air-laid method to bond the fibers to the screen and strengthen the fiber web into a cloth.
- Wet non-woven fabric. The fiber raw materials placed in the aqueous medium are opened into single fibers, and at the same time, different fiber raw materials are mixed to make a fiber suspension slurry, which is sent to the mesh weaving mechanism, the fibers are woven in a wet state, and then reinforced into cloth.
- Spunbond nonwoven fabric. After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a mesh, and the mesh is converted into a nonwoven fabric by self-bonding, thermal bonding, chemical bonding, or mechanical reinforcement methods.
- Needle punched non-woven fabric is a dry non-woven fabric. Needle-punched non-woven fabrics use the puncture effect of the needle to reinforce the fluffy web into a cloth.
As a common production of protective equipment, remind everyone to avoid using the disposable masks all the time, and to do proper treatment after use to avoid others from continuing to use.
