Non -woven cloth breaks through the traditional textile principle, and has the characteristics of short process, fast production speed, high yield, low cost, wide use, and many sources of raw materials. Burning, non -toxic, non -irritating, rich color and other characteristics.

Non -woven fabric production fiber is mainly pallin (PP) and polyester (PET). In addition, there are nylon (PA), adhesive fiber, acrylic, ethalus (HDPE), chlorine (PVC).

According to the application requirements: non -woven fabrics are divided into two categories: disposable application type and durable type.

According to the production process: divided into:

1. Water spurs non -woven fabric: The water test process is to spray high -pressure micro -fine water flow to a layer or multi -layer fiber network, so that the fiber is wrapped in each other, so that the fiber net can be reinforced and has a certain strength.

2. Thermal non -woven fabric: Thermal adhesion non -woven fabric refers to adding fiber or powdery hot melt adhesive material to the fiber net, and the fiber net is reinforced by heating melt and cooling reinforcement.

3. Non -woven meal airflow: airflow net non -woven fabric can also be called dust -free paper and dry paper non -woven fabric. It uses airflow mesh technology to pine wood pulp fiber plates into a single fiber state, and then use the airflow method to condense the fiber on the mesh curtain, and the fiber net is reinforced into cloth.

4. Wet wet woven fabric: The wet non -woven fabric is a fiber raw material placed in the water agglutination into a single fiber, and at the same time mix different fiber raw materials, make fibrous floating slurry, and transport the suspended slurry to the network institution. Fiber is reinforced into a cloth in a wet state.

5. Spinning non -woven fabric: The spinning non -woven fabric is squeezed out and stretched to form continuous long silk. The long silk is laid into a net. The adhesive or mechanical reinforcement method makes the fiber net become non -woven.

6. Follow-spray non-woven fabric: The process of melting spray non-woven fabric: The polymer is fed --- melting extruded --- fiber formation --- fiber cooling --- net-reinforced cloth.

7, acupuncture non -woven fabric: acupuncture non -woven fabric is a type of dry method non -woven fabric. Acupuncture non -woven fabrics use the puncture effect of thorns to strengthen the fluffy fiber mesh into cloth.

8. Sliming non -woven fabrics: sewing non -woven fabrics are a type of dry and woven fabric. The sewing method is to use the coil structure to the fiber mesh, yarn layer, non -textile material (such as plastic sheet, plastic thin thin plastic, thin plastic thin, thin plastic thin, thin plastic thin, thin plastic thin, thin plastic thin Metal foil, etc.) or their combinations are reinforced to make non -woven fabrics.

9, hydrophilic non -woven fabric: It is mainly used for the production of medical and sanitary materials to obtain better feel and not scratching the skin. Sanitary napkins and sanitary pads are hydrophilic functions using hydrophilic non -woven fabrics.
