Non-woven fabric products are colorful, bright and bright, fashion and environmental protection, widely used, beautiful and generous, patterns and styles are diverse, and light, environmental protection, recycling and reuse, is internationally recognized as the environmental protection products to protect the earth's ecology.


Suitable for agricultural film, footwear, leather, mattresses, lash, decoration, chemical industry, printing, automotive, building materials, furniture and other industries, and clothing lining cloth, medical disposable gown, mask, cap, sheet, hotel disposable tablecloth, hairdressing, sauna and even today's fashion gift bag, boutique bags, shopping bags, advertising bags, etc.

Environment-friendly products are widely used and economical.

Because it looks like a pearl, it is also called a pearl canvas.


Nonwoven fabrics are made of chemical fibers and plant fibers in the condition of water or air as a suspension medium in wet or dry paper making machine, although it is cloth without textile, so it is called non-woven fabric.

Non-woven fabric is a new generation of environmental protection materials, with strong, breathable and waterproof, environmental protection, flexible, non-toxic and tasteless, and cheap.

It is a new generation of environmental protection materials, with water repellant, breathable, flexible, non-combustion, non-toxic and non-irritating, colorful and other characteristics.

If the material is placed outdoors through natural decomposition, its longest life is only 90 days, placed indoors in 8 years of decomposition, combustion is non-toxic, harmless, thus does not pollute the environment, so environmental protection comes from this.

classification

Non-woven fabric production with the main fiber is polypropylene (PP), polyester (PET).

In addition, there are nylon (PA), viscose fiber, acrylic, vinyl (HDPE), PVC.

According to the application requirements, non-woven fabric is divided into disposable application and durable two categories.


According to the production process, it is divided into:

1 spunlaced non-woven fabric: spunlaced process is to spray high pressure fine water to a layer or multiple fiber network, so that the fiber intertwined together, so that the fiber network can be strengthened and have a certain strength.


2. Thermal non-woven fabric: thermal bonding non-woven fabric refers to the fiber net in the fiber or powder hot melt bonding reinforcement material, fiber net and then after heating, melting and cooling reinforcement into cloth.


3 pulp air flow into net non-woven cloth: air flow into net non-woven cloth can also be called dust-free paper, dry papermaking non-woven cloth.

It is to use air flow into the net technology will wood pulp fiberboard open loose into a single fiber state, and then use air flow method to make fiber agglutination in the net curtain, fiber net reinforcement into cloth.


4 wet non-woven fabric: wet non-woven fabric is placed in the water medium of fiber raw materials open loose into single fiber, at the same time make different fiber raw materials mixed, made of fiber suspension slurry, suspension slurry transported to the net mechanism, the fiber in the wet state into a net and then strengthened into cloth.


5 spunbonded non-woven fabric: spunbonded non-woven fabric is in the polymer has been extruded, stretched and formed a continuous filament, filament laid into a net, the net after its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that the net into non-woven fabric.


6. Melt-blown non-woven, melt-blown non-woven process: polymer feeding - melt extrusion - fiber formation - cooling - into a network - reinforcement into cloth.


7. Needling non-woven fabric: Needling non-woven fabric is a kind of dry non-woven fabric. Needling non-woven fabric is to use the puncture effect of needles to reinforce the fluffy fiber net into cloth.


8. Stitched non-woven fabric: Stitched non-woven fabric is a kind of dry non-woven fabric. Stitched knitting method is to use the warp knitting coil structure to reinforce the fiber net, yarn layer, non-textile materials (such as plastic sheet, plastic thin metal foil, etc.) or their combination to make non-woven fabric.


9. Hydrophilic non-woven fabric: mainly used in the production of medical and health materials, in order to get a better feel and do not scratch the skin.

Like sanitary napkin, sanitary gasket is the use of hydrophilic nonwoven hydrophilic function.
