What Are The Raw Materials For Non-Woven Fabrics?
The main fibers used in the production of non-woven fabrics are polypropylene (PP) and polyester (PET). In addition, there are nylon (PA), viscose fiber, acrylic fiber, ethylene fiber (HDPE), and chloroprene fiber (PVC). According to application requirements, non-woven fabrics are divided into two categories: disposable and durable.
According to the production process, it is divided into
1. Spunlaced non-woven fabric: The Spunlaced process involves spraying high-pressure micro water onto one or more layers of fiber mesh, causing the fibers to intertwine with each other, thereby strengthening the fiber mesh and providing a certain degree of strength.
2. Heat-bonded non-woven fabric: Heat-bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials to the fiber mesh, which is then heated, melted, and cooled to form a fabric.
3. Pulp air flow net forming non-woven fabric: Air flow net forming non-woven fabric can also be called dust-free paper or dry paper making non-woven fabric. It uses airflow mesh forming technology to loosen the wood pulp fiberboard into a single fiber state, and then uses airflow method to aggregate the fibers onto the mesh curtain, and the fiber mesh is reinforced into a cloth.
4. Wet non-woven fabric: Wet non-woven fabric is the process of loosening fiber raw materials placed in a water medium into single fibers, and mixing different fiber raw materials to create a fiber suspension slurry. The suspension slurry is transported to a mesh forming mechanism, and the fibers are formed into a mesh in the wet state and then reinforced into a fabric.
5. Spunbonded non-woven fabric: Spunbonded non-woven fabric is a continuous filament formed by the extrusion and stretching of polymers, which is laid into a web. The web is then self bonded, thermally bonded, chemically bonded, or mechanically reinforced to turn the web into non-woven fabric.
6. Melt blown non-woven fabric: The process of melt blown non-woven fabric includes polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh formation - reinforcement into fabric.
7. Needled non-woven fabric: Needled non-woven fabric is a type of dry process non-woven fabric, which uses the puncture effect of a needle to reinforce a fluffy fiber mesh into a fabric.
8. Stitching non-woven fabric: Stitching non-woven fabric is a type of dry process non-woven fabric, which uses warp knitted coil structure to reinforce fiber mesh, yarn layer, non-woven materials (such as plastic sheets, plastic thin metal foil, etc.) or their combination to make non-woven fabric.
9. Hydrophilic non-woven fabric: mainly used for the production of medical and health materials to achieve better hand feel and avoid scratching the skin. Like sanitary napkins and sanitary pads, they utilize the hydrophilic function of hydrophilic non-woven fabrics.
