What is the raw material of nonwoven fabric?

The fibers used for nonwoven production are mainly polypropylene (PP) and polyester (PET). In addition, there are polyamide (PA), viscose fiber, acrylic, ethylene (HDPE), chlorine (PVC). According to the application requirements, nonwoven fabrics are divided into two main categories: disposable application type and durable type.

Based on the production process is divided into:

PET polyester nonwoven fabrics

1. Hydroentanglement nonwoven fabrics: hydroentanglement process is a high-pressure micro-fine water jet to one or more layers of fiber mesh, the fibers are entangled with each other, so that the fiber mesh can be reinforced with a certain strength.

2. Thermally bonded nonwoven fabrics: thermally bonded nonwoven fabrics is the fiber network in the addition of fiber or powder hot melt bonding reinforcement materials, fiber network and then heated and melted and cooled to reinforce the cloth.

3. Pulp airflow into the net nonwoven fabric: airflow into the net nonwoven fabric can also be called as dustless paper, dry paper nonwoven fabric. It is the use of airflow into the network technology will be wood pulp fiber board open into a single fiber state, and then use the airflow method to make the fiber coagulation in the net curtain, the fiber network and then reinforced into the cloth.

4. Wet nonwoven fabric: wet nonwoven fabric is placed in the water medium fiber raw materials into a single fiber open, while making different fiber raw materials mixed, made of fiber suspension pulp, suspension pulp transported to the netting mechanism, the fiber in the wet state into the net and then reinforced into cloth.

5. Spunbond nonwoven fabrics: spunbond nonwoven fabrics are in the polymer has been extruded, stretched to form continuous filaments, filaments laid into a network, fiber network and then after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement methods, so that the fiber network into a nonwoven fabric.

6. Meltblown nonwoven fabrics: meltblown nonwoven fabrics process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- into the network --- reinforcement of cloth.

7. Needle-punched nonwoven fabrics: needle-punched nonwoven fabrics is a kind of dry nonwoven fabrics, needle-punched nonwoven fabrics is the use of felting needles puncture, the fluffy fiber mesh reinforcement into cloth.

8. Sewn Nonwoven Fabric: Sewn Nonwoven Fabric is a kind of dry nonwoven fabric, sewing method is the use of warp knitting coil structure on the fiber mesh, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or a combination of them for reinforcement, in order to make nonwoven fabric.

9. Hydrophilic nonwoven fabrics: mainly used in the production of medical and hygiene materials, in order to achieve a better feel and not scratch the skin. Like sanitary napkins, sanitary pads is the use of hydrophilic nonwoven hydrophilic function.
