What is Spunbond Fabric
Spunbond fabric is a polyester nonwoven fabric produced by spunbonded method.
At present, the most common nonwoven fabric on the market is made of spunbond nonwoven fabric by spunbond method
The importance of spun bonded fabric
Non-woven fabric is called spinning, its importance can not be ignored. It is made of polyethylene, polypropylene, polyurethane and other materials made of non-woven cloth, it has many advantages, such as its fabric is very light, has excellent flexibility and elasticity, water resistance is also very good, so as to prevent water penetration, can also prevent the air pollutants into, so as to ensure that the covered objects clean health.
Nonwovens have various uses in China:
One is for the automotive industry. It can be used to make car seats to improve the comfort of the car, and its water resistance can also prevent the car interior from becoming damp.
Second is for home decoration. It can be used to make furniture such as sofas, tables, chairs, etc., to improve the quality of furniture, and it can also resist dust and pollutants to keep the home environment clean and hygienic.
Third is for the medical industry. It can be used to make medical supplies such as pillows, mattresses, etc., to improve the comfort of patients, and its anti-bacterial properties can also prevent the spread of viruses and infections.
In short, the importance of nonwovens in China cannot be ignored. It can be used in the automotive industry, home decoration and medical industry to improve the product quality of each industry and improve people's quality of life. Nonwovens are an important foundation for China's future development and also a booster for China's development.
Spunbond Fabrics Vs Non-woven Fabrics
- Spunbond fabric, usually refers to polyester spunbond fabric or polypropylene spunbond fabric. The composition of nonwoven fabric covers a broader range, such as polyester, polypropylene, acrylic, etc
- Due to the characteristics of high density and high temperature resistance, spunbond fabric can be distinguished from non-woven fabric by high temperature test.
Spunbond process
Spunbonded process is a combination of synthetic fiber spinning technology and nonwovens netting and consolidation technology. The following is a look at the production process of spunbond nonwovens:
- The dried polymer is fused and pressurized by a screw extruder
- The filament with a certain fineness is ejected from the spinneret assembly
- Next, use air cooling to form a fiber net on the mesh curtain
- The fiber net is reinforced so that the fibers are bonded into a spunbond nonwoven fabric with certain mechanical properties
Spunbonded nonwovens can be used to increase the mechanical properties of the whole material and improve the service life of the material, which has a great application prospect in the market.
Due to the special production technology of spunbond nonwoven fabric, it has the following characteristics:
- With high temperature resistance characteristics, and different raw materials have different degrees of high temperature resistance, such as polypropylene can be used in 150℃ environment, polyester can be used in 260℃ environment
- Good air permeability and water extraction
- Anti-aging, corrosion resistance, good stability
- Sound insulation, moth-proof, non-toxic
The application of spunbond nonwoven fabric
- Agricultural field: spunbond nonwoven fabric is often used as agricultural harvest cloth in the agricultural field, such as plant protection cloth, seedling raising cloth, irrigation and heat preservation cloth, etc
- Medical and health field: This kind of fabric is often used as medical and health cloth, and is made into masks, surgical gowns, disinfectant bags, protective clothing and so on
- industrial field: industry, spunbond nonwoven fabric is often used as filtration material, insulation material, coating cloth, cement packaging bag, etc
- Application: flower packaging cloth, hotel daily necessities, furniture lining, wall cloth tablecloth, bed sheets, etc
