The latest policy on environmental protection promotes environmentally safe alternatives to plastic bags. Non woven fabric and their products are a step in this direction. Non woven fabric products can be recycled. Therefore, using non woven fabric products not only saves wood, non-woven products will also attract your environmentally conscious customers.

Reasons for using non woven fabric

1. Durable and stylish

2. The more capacious

3. Can be recycled

4. Reusable

5. More convenient to use and carry

6. Wash

7. Available in a wide range of sizes and finish options

Non woven fabric provide specific functions such as absorption, liquid rejection, elasticity, extensibility, softness, strength, flame retardant redundancy, washing capacity, buffering, filtration, etc. When combined with other materials, they provide products with different properties and, when used alone, can be applied to the manufacturing of clothing components, furniture, health care, engineering, industry and consumer goods.

The characteristics of non woven fabric

1. Durability, disposable. Insulation, nonconductive. Softness, rigidity. Fineness, expansibility, isotropy.

2. Softness: Composed of fine fibers (2-3D), light-point hot-melt bonding molding. The finished product has moderate softness and comfort.

3. Water diversion and air permeability: The polychip is non-absorbent, with zero moisture content, and the finished product has good water displacement. It is composed of 100% fibers with good porosity and air permeability, and easy to keep the cloth dry and easy to wash.

4. Non-toxic and non-irritating: the product is made from food grade raw materials conforming to FDA. It does not contain other chemical ingredients, has stable performance, is non-toxic, odorless and does not irritate skin.

5. In terms of environmental protection, the raw material of most non woven fabric is polypropylene, while the raw material of plastic bags is polyethylene. Although the two substances have similar names, their chemical structures are far from each other.

The chemical molecular structure of polyethylene has strong stability and is difficult to be degraded, so it takes 300 years for plastic bags to be decomposed. Polypropylene, on the other hand, is chemically weak, its molecular chains easily break down and can be degraded, leaving it in a non-toxic form for the next environmental cycle: a non-woven shopping bag can be completely broken down within 90 days.

Moreover, non-woven shopping bags can be reused for more than 10 times, and the pollution degree of waste bags is only 10% of that of plastic bags.

Classification and application of non woven fabric

According to application requirements: non woven fabric can be divided into disposable and durable types.

According to the production process, it can be divided into:

1. Spunlaced non woven fabric: Spunlaced technology is to spray high pressure and micro water into one or more layers of fiber network, so that the fibers are entangled with each other, so that the fiber network can be strengthened and has a certain strength.

2. Thermal bonding non-woven: Thermal bonding non-woven refers to adding fiber or powder thermal bonding reinforcement materials into the fiber net, which is then strengthened into cloth by heating, melting and cooling.

3, pulp into net non-woven cloth: air into net non-woven cloth can also be called dust-free paper, dry paper non-woven. It is the use of airflow into the network technology will be the wood pulp fibreboard loose into a single fiber state, and then use the airflow method to make the fiber agglutination in the net curtain, the fiber net reinforcement into cloth.

4. Wet non-woven cloth: Wet non-woven cloth is made by loosening the fiber raw materials in the water medium into a single fiber, and mixing different fiber raw materials to make the fiber suspension pulp, which is transported to the net-forming mechanism, and the fiber is formed into a net in the wet state and then strengthened into cloth.

5. Spunbonded non woven fabric: Spunbonded non woven fabric is made of continuous filament after the polymer has been extruded and stretched, the filament is laid into a net, and the fiber net is then bonded by itself, thermal bonding, chemical bonding or mechanical reinforcement to make the fiber net into non woven fabric.

6. Melt spray non-woven cloth: the process of melt spray non-woven cloth: polymer feeding -- melt extrusion -- fiber formation -- fiber cooling -- mesh forming -- reinforcement into cloth.

7. Needling non-woven cloth: Needling non-woven cloth is a kind of dry non-woven cloth. Needling non-woven cloth takes advantage of the puncture effect of needling needles to strengthen the fluffy fiber net into cloth.

8. Stitched non woven fabric: Non woven fabric is a kind of dry non woven fabric. Stitched fabric is made by reinforcing the fiber net, yarn layer, non-textile material (such as plastic sheet, plastic thin metal foil, etc.) or their combination by using warp knitting coil structure.

9. Hydrophilic non woven fabric: mainly used in the production of medical and sanitary materials to achieve better hand feeling and avoid skin scratch. Like sanitary napkin, sanitary gasket is the use of hydrophilic non woven fabric hydrophilic function.

Applications of non woven fabric:

1. Geosynthetics

Geosynthetics is a kind of high - tech, high - value industrial textile material. Non-woven geotextiles mainly include: spunbonded geotextiles, staple fiber needled geotextiles, hot-melt bonded geotextiles, geogrids and grids, geofilm, composite geotextiles. Geotextile has the functions of reinforcement, isolation, filtration, drainage and seepage prevention in geotechnical buildings.

2. Non woven filter materials

Filtering materials have become an essential and important product in modern society. As a new type of filter material, nonwoven filter material is gradually replacing the traditional textile filter material due to its unique three-dimensional network structure, uniform distribution of pores, good filtration performance, low cost and variety of advantages. It has become the leading product of the filter medium with a very fast development speed.

3. Non woven fabric for medical and health purposes

non woven for medical use is a product with development potential. It gives full play to the advantages of fiber as a health care material, and it is the product of a new industrial discipline formed by the integration and crossover of various disciplines. Including operating clothes, protective clothing, disinfectant cloth, face mask, diaper, civil dishcloth, wiping cloth, wet towel, magic towel, soft towel roll, beauty products, sanitary towel, sanitary pad, and disposable sanitary cloth, etc.

4. Agricultural non woven

Agricultural non woven has long service life, good effect and low investment, and popularization of agricultural non woven is conducive to promoting agricultural modernization. Agricultural USES mainly for cover pad, heat insulation, heat preservation, wind barrier, fruit protection, disease and insect prevention, seedling, seeding, covering and so on.

5. Non-woven clothing

The non woven fusible interlining used for clothing is characterized by light weight, softness, low cost, wide variation range of thickness, strong adaptability, nondirectional arrangement of fibers and large flexibility, which is easy to be compatible with various fabrics. Including lining, adhesive lining, flocculation, set cotton, all kinds of synthetic leather bottom cloth.

6. Household decoration, household articles and packaging materials

It mainly refers to non woven fabric used in sofa and bed linings, curtains and curtains, tablecloths, household appliances cover cloth, suit jacket, car interior decoration, car protective cover, wiping cloth, equipment materials, commodity packing cloth, etc.
